High-voltage switcher Frequently Asked Questions and solutions
 
A, VS1 + indoor high voltage vacuum circuit breaker
 
1, fault phenomenon: withdrawable circuit breaker in the test location and the location can not be manual and electrical closing. Turn the power switch on if the long-term, it will burn closing coil.
Reason: Although the location of the cabinet light has been lit, but the circuit breaker mechanical interlock part of the not yet fully in place, then still in the interlock state.
   Solutions: Used roll into the roll out, the position of the handle should be shaking in the test head, this time should be able to hear the "despair" is heard, indicating that the mechanical parts are in place.
 
2, fault phenomenon: not manual or electric switch.
   Reasons: 1, latch circuit does not connect, circuit breaker in the latch state.
2, blocking the supply voltage is not within range, the coil can not be reliably blocking action.
   Solutions: 1, latch circuit connected to the power, to lift the latch.
2, check the power supply voltage lockout, to conform to requirements.
 
3, fault phenomenon: electric switch is not reliable.
Reason: duplication of circuit breakers and switchgear anti-jump circuit, mutual interference.
Solutions: cancel one of the anti-jumping circuit.
 
4, fault phenomenon: over-current trip does not operate.
Reasons: over-current trip circuit board power is applied.
Solutions: tripping circuit board connected by stream power.
 
5, fault phenomenon: not electric energy storage, not electric switch, not electric sub-gate.
Reasons: 1, the second power is applied
2, the second power supply voltage not within range.
3, connected with the cabinet air plug is not inserted tightly.
4, the circuit breaker within the second sub connector loose.
Solutions: 1, connected to the second power.
2, check the secondary power supply voltage, to conform to requirements.
3, insert air tight plug.
4, open the circuit breaker panel, check the connectors and plug tight.
 
Two, ZW8-12 Outdoor high voltage vacuum circuit breaker
 
1, fault phenomenon: the circuit breaker switch is not in place, inseparable.
Reason: closing spring tension is too small.
The solution: 1, can be electric or manual to energy storage in place, re-closing, closing should be able to put in place.
2, manual body, remove the hole with a thin even sheet waist, so that the pawl body reset, re-storage, closing in place.
3, for 10 points closing operation, should be normal, if not in place closing the phenomenon of the body to tighten the spring on the switch, you can increase the closing force.
 
2, fault phenomenon: circuit-breaker closing.
Reasons: 1, volume rocker and the axle is too small fastening.
2, the rocker arm and axle clearance is too small.
3, the isolation switch closing is not in place.
Solutions: 1, according to the CT23 manual adjustment.
2, the isolation switch closing place.
 
Three, ZW32-12 Outdoor high voltage vacuum circuit breaker
 
1, fault phenomenon: change change.
Reason: According to user requirements change.
Solutions: Press twice to change the wiring diagram instructions.
 
2 Failure: adjust the inrush current parameters.
Reason: According to user requirements change.
Solutions: Anti-surge controller by manual adjustment.
 
3, fault phenomenon: switch not closing.
Reasons: 1, agencies are not energy storage.
2, the switch signal is not access.
Solutions: Check wiring according to wiring diagram to ensure the normal power supply energy storage sub-closing.
 
Four, JN15-12 indoor HV earthing switch
 
1, fault phenomenon: earthing not close.
Reason: auxiliary contact barrier.
Solutions: Check the cabinet interlock, check whether the grounding blade into place.
 
2, fault phenomenon: the cabinet is no live show.
Reasons: 1, sensor damage.
2, the second cable is loose.
Solutions: 1, check the sensor is damaged.
2, check the second line connection is solid.
 
Five, ZN28-12 Indoor High Voltage Vacuum Circuit Breaker
 
1, failure phenomena: circuit breakers resist together.
Reason: Auxiliary switch off prematurely closing coil, closing coil failed to promote closing axle, resulting in combined circuit breaker or switch is not in place to resist.
Solutions: regulation and institutions should be linked pole auxiliary switch, auxiliary switch contacts make contact with reliable, on time.
 
2, fault phenomenon: circuit breaker refuse points.
Reason: failed to place the sub-gate axle.
Solutions: should adjust the angle of rotation axle sub-gate, so that in the sub-gate solenoid driven to fully rotate the sub-gate location.
 
Six, FZW32-12 outdoor high-voltage vacuum isolation load switch
 
1, fault phenomenon: switch closing is not in place.
Reason: too loose in the spring or jamming.
Solutions: adjusted in the spring.
 
2, fault phenomenon: the sub-gate switch is not in place.
Reasons: 1, sub-gate spring loose.
2, over the spring jam.
Solutions: 1, tighten the sub-gate spring.
2, adjusted in the spring.
 
Seven, ZW7-40.5 outdoor high voltage vacuum circuit breaker
 
1 Failure: the circuit breaker switch is not in place.
Reasons: 1, closing spring output power is not enough.
2, transmission parts catching.
Solutions: 1, tighten the closing spring.
2, check all transmission parts.
 
2 Failure: circuit breaker refuse points.
Reasons: 1, sub-gate coil.
2, the sub-gate spring loose.
3, transmission parts catching.
Solutions: 1, replace the sub-gate coil.
2, adjusting brake springs.
3, check all transmission parts.
 
Eight, FZN21-12 indoor high voltage vacuum load switch
 
1, fault phenomenon: not energy storage and closing.
Reasons: 1, grounding switch in the closing state.
2, electrical energy storage, full-wave bridge rectifier, auxiliary switch is damaged or loose wiring.
3, the fuse hit out.
Solutions: 1, open ground switch.
2, one by one check and replace damaged components.
3, replace the fuse.
 
2, fault phenomenon: closing is not in place.
Reasons: 1, sub-gate coil.
2, the sub-gate spring loose.
3, transmission parts catching.
Solutions: 1, replace the sub-gate coil.
