◆ Anti-error device
The function of "Five Preventions" is to prevent the circuit breaker from being divided and closed by mistake; Prevent on-load misoperation and misoperation of isolating switch; Prevent the grounding switch from closing when it is charged; Prevent the grounding switch from being turned on when it is closed; Prevent from entering the charged interval by mistake.
This XGN2-12 type Box Type Fixed Metal Closed Switchgear adopts the compulsory mechanical locking mode, and the locking device is composed of main components such as support, disc, panel, locking plate, handle, connecting rod, etc., which has the characteristics of reliable performance, complete functions, simple structure and convenient operation, thus achieving the "five precautions" simply and effectively:
▶ The control switch (KW switch) with red and green flop is used in the circuit breaker scheme to prevent the circuit breaker from being divided and closed by mistake
▶ Only after the circuit breaker is really broken can the small handle be pulled out from the "working" position and turned to the "breaking and locking" position; Opening and closing isolating switch; Prevent 7-load disconnecting switch from opening and closing. The reversibility of locking and anti-locking has double anti-misoperation functions, that is, when the small handle is in the "breaking locking" position, only the upper and lower disconnectors can be turned on and off, but the circuit breaker cannot be turned on and off, thus avoiding the misoperation of the circuit breaker
▶ When the circuit breaker and the upper and lower disconnectors are in the closed state, and the small handle is in the "working" position, the front and rear cabinet doors cannot be opened, so as to prevent them from entering the live interval by mistake
▶ When the upper and lower disconnectors are not opened, the grounding switch cannot be closed, and the small handle cannot be turned from the "breaking and locking" position to the "maintenance" position, which can prevent the grounding wire from being hung with electricity
▶ If the earthing switch is not opened, the upper and lower disconnectors cannot be closed, which can prevent the earthing wire from closing the upper and lower disconnectors.
