Spring operating mechanism special for 12kV, SF6 inflatable ring net cabinet integrated electrical unit.
With the function of energy storage and holding, electric module can be added to the manual operation mechanism to assemble the hand and electric integrated operation mechanism.
Rigid interlocking device, with switching cable room door panel interlocking device, a padlock to solve isolation, ground conversion, prevent misoperation of high reliability.
China F cabinetcircuit breaker operating mechanism has tripping interlock device for easy installation and maintenance.
Mechanical life: 6000 times
Operating voltage: AC/DC (24V/48V/ 110V/220V optional)
a. Close all cabinet doors and rear sealing panels, and lock them.
b.Insert the operating handle of the grounding switch into the hexagonal hole on the lower right side of the middle door, turn it counterclockwise about 90°, put the grounding switch in the opening position, take out the operating handle, and the interlocking plate at the operating hole will automatically spring back to cover the operation hole, and the rear door of the switchgear is locked.
c.Observe whether the instruments and signal indications on the upper cabinet door are normal. Under normal conditions, the power light of the microcomputer protection device is on, the handcart test position light, the China F Cabinet Circuit Breaker Operating Mechanism opening indicator light and the energy storage indicator light are on. If all the indicator lights are off, open the upper cabinet door and confirm the power switch of each busbar. Whether it is closed, if the indicator lights are still off after closing, you need to check the control circuit.
d.Insert the handle of China F Cabinet Circuit Breaker Operating Mechanism handcart into the socket of the handle and press it down firmly, turn the handle clockwise, the 6KV switchgear will rotate about 20 circles, and the handle is obviously blocked and accompanied by “click” Take off the crank handle when the sound is heard, the handcart is in the working position at this time, the secondary plug is locked, the main circuit of the China F Cabinet Circuit Breaker Operating Mechanism handcart is connected, check the relevant signals (at this time the light of the handcart working position is on, and at the same time the handcart test The position light is off), and at the same time, it should be noted that when the handcart is in the working position, the interlock plate at the operation hole of the floor knife is locked and cannot be pressed.
e.Operate the closing and opening switch of the instrument door to close the China F Cabinet Circuit Breaker Operating Mechanism and transmit power. At the same time, the red closing indicator light on the instrument door is on, and the green opening indicator light is off. Circuit Breaker Operating Mechanism Mechanical on-off position and other related signals, everything is normal, power transmission is successful (when operating the on-off switch, turn the operating handle clockwise to the closed position indicated on the panel, and the operating handle should automatically reset to pre-closed position).
f.If China F Cabinet Circuit Breaker Operating Mechanism automatically opens after closing or automatically opens during operation, it is necessary to judge the cause of the fault and eliminate it before re-powering according to the above procedure.
a.The equipment of F Cabinet Circuit Breaker Operating Mechanism manufacturer has a reliable interlocking device, which meets the requirements of the five defenses and effectively guarantees the safety of operators and equipment.
a. The door of the instrument room is equipped with a prompt button or switch to prevent the circuit breaker from being closed or opened by mistake.
b. China F Cabinet Circuit Breaker Operating Mechanism When the handcart is in the test position or working position, the circuit breaker can be closed and opened. After the circuit breaker is closed, the handcart cannot move, which prevents the handcart from being pushed by mistake with load.
c. China F Cabinet Circuit Breaker Operating Mechanism handcart can move from the test/overhaul position to the working position only when the grounding switch is in the opening position. Only when the handcart of the circuit breaker is in the test/inspection position, the grounding switch can be closed. In this way, the grounding switch can be prevented from being switched on by mistake, and the circuit breaker can be prevented from opening and closing when the grounding switch is in the closed position.
d. When the grounding switch is in the opening position, the lower door and the rear door of the switch cabinet cannot be opened, which prevents mistaken entry into the electrified interval.
e. When the handcart of the circuit breaker is in the test or working position and there is no control voltage, it can only be opened manually but not closed.
f. When the China F Cabinet Circuit Breaker Operating Mechanism handcart is in the working position, the secondary plug is locked and cannot be pulled out.
