Structure and Working Principle

1. Core structure (including component functions)

Core functions of structural components

Pole component (1) vacuum arc extinguishing chamber (6), upper/lower arc extinguishing chamber bracket (5/7), post insulator (3) 1. Vacuum arc extinguishing chamber: based on more than 40 years of mature vacuum switch technology, arc extinguishing is achieved; 2. Air insulation design, easy to clean insulation components; 3. Bear the external force and contact pressure of switch operation

Operating mechanism box (2) includes energy storage mechanism, release device, auxiliary switch, indicator, and actuator 1. It accommodates all operating mechanisms; 2. The configuration of secondary devices can be adjusted according to application scenarios to meet diverse needs

Transmission component operating rod (4), lever transmission switch action, connecting operating mechanism and pole assembly

2. Key operational mechanisms

Energy storage mechanism: The closing spring is an energy storage component that can store energy electrically or manually, and is locked after the energy storage is completed; When closing, unlock through the local “ON” button (mechanical) or remote control (electric). During the closing process, charge the opening/contact pressure spring, and automatically re store energy after discharge. It supports the OPEN-CLOSE-OPEN operation sequence.

Free release mechanism: in accordance with IEC 62271-100, if a closing command is issued and an opening command is received, the moving contact returns to the opening position and maintains it, avoiding continuous closing opening “pumping”.

Closing method:

Standard configuration: Remote electric closing, local mechanical unlocking closing spring (manual mechanical closing)

Optional configuration: Manual electric closing (electrically controlled closing circuit through button, compatible with switch equipment interlocking)

3. Types and functions of release devices

Release type, power supply method, core function

Closing the soleoid DC/AC unlocks the stored energy closing spring to achieve electrical closing

External power supply (DC/AC) for shunt release, connected to voltage transformer in special circumstances. 1. Automatic disconnection through protective relay; 2. Electrical manual disconnection

When the CT operated release has no external auxiliary power supply (such as no battery), it is triggered by a protective relay (such as overcurrent time protection). When the tripping current exceeds 90% of the rated normal current, the energy storage mechanism is unlocked and the circuit is opened

When the undervoltage release circuit breaker is closed, it is permanently connected to the secondary/auxiliary voltage. When the voltage is lower than the preset value, it is unlocked and opened through the energy storage mechanism; 2. Can be connected to a voltage transformer, which automatically opens when the voltage is too low; 3. Can be paired with energy storage components to achieve delayed disconnection\

Environmental conditions and technical parameters

1. Environmental conditions (compliant with IEC 60721-3-3)

Key limitations of environmental category level

The lower limit of low temperature in the 3K4 climate environment is -5 ℃, with no icing or wind blown precipitation

Biological Environment 3B1-

Mechanical environment 3M2-

Chemical active substance 3C2-

Mechanical active substance 3S2 requires cleaning of insulation components

2. Current carrying capacity and insulation strength

Current carrying capacity: The rated normal current is based on an ambient air temperature of 40 ℃ (open type switchgear), and can be increased when the temperature is below 40 ℃. The rated current levels include 1250A, 2000A, 2500A, 3150A, 4000A, 5000A, and 6300A (corresponding to characteristic curves 1-7).

Insulation strength:

Reference conditions: At an altitude of 1000m (above sea level), the rated lightning impulse withstand voltage and rated short-time power frequency withstand voltage are taken according to the “Technical Data” section.

High altitude correction: When the altitude is greater than 1000m, it needs to be adjusted according to the formula U ≥ U 0 × K a (U is the reference environmental withstand voltage, U 0 is the required withstand voltage of the installation site, K a is the altitude correction factor, which increases with altitude).

Example: When a lightning impulse withstand voltage of 75kV is required at an altitude of 2500m, the reference environment must be at least 90kV (90kV ≥ 75kV × 1.2).

Probe: Made of polycarbonate material (RAL 7001), the end sensing element is protected by a filter cap to prevent dust contamination.

2. Installation method and requirements

Key requirements for installation method and operation steps

Install flange (recommended) 1. Assemble the flange with the sensor; 2. Fix the flange to the air duct according to the required immersion length; 3. Insert the sensor and tighten it to adjust the immersion length as needed. The flange material is PA66 (black)

No installation flange 1. Use 4 mounting holes on the shell; 2. Directly screw the sensor onto the air duct using the maximum immersion length to ensure measurement representativeness

Special scenario (dew point offset) 1. Only fix the flange to the air duct wall; 2. Insert the sensor from the flange and clamp it tightly. It must be installed in the return air duct to avoid measurement deviation

Installation taboos:

Avoid probe impact: Sensing components are easily damaged by impact and should be handled gently during installation;

Distance between steam humidifiers: The minimum distance from the humidifier should be ≥ 3m (recommended ≤ 10m) to prevent sudden humidity changes from affecting accuracy;

Sealing protection: It is forbidden to remove the seal between the shell and the cover plate to prevent water vapor from entering and damaging the circuit.

Parameter configuration and debugging

1. Jumper configuration (on PCB, under cover)

The jumper has 6 pins and 1 jumper cap, which is used to select temperature range, display unit, and activate testing functions. The specific configuration is as follows:

Configure the parameters corresponding to the jumper position of the configuration function

Temperature range selection left (1) -31 ° F~95 ° F (-35 ℃~35 ℃)

Right position (3) -40 ° F~158 ° F (-40 ℃~70 ℃)

Display unit selection (with LCD model) vertical right position Celsius (℃, factory default)

Vertical left Fahrenheit (℉)

Test function activation level signal output specific values (such as 0V/10V, 4mA/20mA) for troubleshooting

2. Debugging steps

Wiring inspection: Confirm that the power and signal lines are connected correctly (refer to the terminal definition in Figure 2-6, for example, QFM3171 needs to ensure that G1/I1 is powered on, even if only temperature output is used);

Range configuration: According to on-site requirements, set the temperature range and display unit through jumper wires;

Power on verification: Connect the power supply and check if the output signal (humidity 0-10V/4-20mA, temperature corresponding range signal) is normal. For models with LCD, it is necessary to confirm the alternating display of temperature and humidity (5-second interval).

Fault diagnosis and spare parts

1. Fault diagnosis (output characteristics when sensor failure occurs)

Fault type: Humidity signal output (U1/I1) Temperature signal output (U2/I2) Remarks

Temperature sensor fault rises to 10V (0-10V output) or corresponding 20mA (4-20mA output) drops to 0V (0-10V output) or corresponding 4mA (4-20mA output). The fault is immediately triggered

The humidity sensor malfunctions for 60 seconds and then rises to 10V/20mA to maintain normal output with a delay of 60 seconds, making it easier for the system to identify

2. Spare parts list (for replacement)

Warning: The red safety symbol does not provide protection and may cause death/serious injury. Contact with rotating parts and burns on high-temperature surfaces

CAUTION yellow safety symbol may cause minor injury if not protected. Foreign objects may splash during compressed air cleaning

NOTICE unsigned and unprotected may cause property damage, cable shielding errors, and loose bolts

2. Special hazard prevention and control

Electric shock hazard:

Risk: When live parts are exposed, the contact voltage can be fatal, and there may still be residual voltage of ≥ 60V at the terminals after power failure;

Prevention and control: Strictly follow the “5 safety rules” (power-off → anti misoperation → electricity inspection → grounding → protection of adjacent live parts), and match the PE wire cross-section with the phase wire (PE=S when S ≤ 25mm ², PE=0.5S when S>50mm ²).

Danger of rotating parts:

Risk: unprotected rotating components such as fans and couplings can easily cause entanglement injuries;

Prevention and control: It is necessary to install a protective cover. After stopping the machine, wait for the rotor to come to a complete stop (≥ 5 minutes) before removing the protective cover.

High temperature hazard:

Risk: The temperature of the winding/bearing during motor operation may exceed 100 ℃, and the temperature may further increase during anti condensation heating operation;

Prevention and control: Stick a “hot surface” label, cool for at least 30 minutes before maintenance, and interlock the anti condensation heating with the main motor (heating is turned off when the motor is running).

Maintenance and troubleshooting

1. Regular maintenance

Maintenance cycle: The cycle should be defined based on the corrosiveness of the medium and the concentration of environmental dust (such as once every 3 months for strong corrosion scenarios and once every 6 months for cleaning scenarios).

Core maintenance project:

Precautions for maintaining project steps

Sealing inspection 1. Clean the shell and seal; 2. Check for cracks/damage; 3. Lubrication or replacement of differential pressure equipment seals requires Siemens authorized personnel to operate

Anti static tools should be used in hazardous areas where the dust layer on the surface of the dust cleaning and removal equipment is greater than 5mm to avoid the accumulation of static electricity

Use a soft brush and an appropriate solvent to clean film deposits. Do not use sharp tools to avoid scratching the film

Parameter calibration: Regularly verify the range and zero point (e.g. every 6 months) using a standard pressure source and record calibration data

2. Fault handling

Fault indication method:

SDP panel: indicates faults through a combination of on/off/flashing of 2 LEDs (such as alternating flashing of dual lights=RAM fault);

BOP/AOP panel: displays Fxxx fault codes (such as F0001=ground fault) or Axxx alarm codes (such as A0002=over range alarm);

HART/PA/FF: View detailed fault information (such as sensor disconnection, EEPROM failure) through communication tools.

Common troubleshooting solutions:

Fault code, fault type, possible causes, and solutions

F0001 grounding fault 1. Motor power does not match equipment; 2. Cable grounding; 3. Equipment overload: 1. Check P0307 (motor power); 2. Check the insulation of the cable; 3. Reduce load

F0002 DC bus overvoltage 1. Input voltage exceeds the range; 2. The slope descent time is too short; 3. The regenerative energy of the load is high. 1. Check the power supply voltage (which should be between 10.5-45V DC); 2. Increase P1121 (slope descent time); 3. Install a braking unit

F0051 EEPROM fault EEPROM read/write failure 1. Perform factory reset (P0010=30+P0970=1); 2. Replace the electronic unit (if reset is ineffective)
