There breaker before wiring board after board, plug-in, slide-in, the user if no special request, according to former board supplier, Front connection is a common wiring. 1, after the board Wiring: Wiring the biggest feature is the rear panel can be replaced or repaired Wuhan High Voltage Vacuum Circuit Breaker breaker, without re-wiring Hebi voltage vacuum circuit breaker, only the pre-power-off. 2, plug-in terminal: the mounting plate complete sets of equipment, install a circuit breaker mount, the mount 6 plugs, there are six outlet connecting plate breaker. 3, drawer type wiring: circuit breaker out of the drawer by clockwise or counterclockwise rotation of the rocker, in the main circuit and the secondary circuit are used in a circuit breaker plug-in structure, fixed omitted necessary isolator, so that a machine with two, improve the economy of use, at the same time to the operation and maintenance has brought great convenience, increased security and reliability. In particular seat drawer knife block Yichang touch the main circuit voltage vacuum circuit breaker, with NT-type knife fuse breaker common touch, so the state of emergency in the power supply can be plugged directly into the fuse. Breaker "rejecting" failure analysis to determine the method is as follows: 1. Check whether caused by low voltage power supply for the trip. 2. Check the trip circuit is intact, if the action is good and the circuit breaker tripped core rejecting, then a mechanical failure. 3, if the power supply is good, if the core action and weak, the core jam or malfunction caused by rejecting the coil may be faulty electrical and mechanical aspects simultaneously. 4, if the operating voltage is normal, after the operating core does not move, it is likely caused by an electrical fault, "rejecting." Common aspects of electrical and mechanical failures were: · There are electrical reasons: control circuit blown fuse or tripped circuit components such as control switches for each contact, breaker auxiliary contact actuator, anti-hop relay and relay tripping Loop and other bad; tripping circuit break or trip coil burned; relay setting value is incorrect; the DC voltage is too low, less than 80% of rated voltage. · Mechanical reasons are: lack of impact tripping core action, indicating that the core may jam or tripping core loss; contact welding or mechanical jam occurs, the transmission part of the fault (eg pin off, etc.).
