Description

A kind of rear door of switch cabinet novel trans locking device
Technical field
The utility model relates to a kind of switch cubicle accessory, is specifically related to a kind of switch cubicle backlocking device.
Background technology
Switch cubicle is a kind of equipment for power transmission and distribution, and therefore, the requirement of its fail safe aspect is higher.Under normal circumstances, when switch cubicle power-off inspecting state, back door is normally opened, but simultaneously, the situation that back door is opened, switch cubicle also can carry out power transmission, and this is a drawback.
At present, what the back door backlocking device in power distribution cabinet equipment had is not also equipped with, and some is equipped with easy locking device, as door latch apparatus after the locking of electromagnetic type back door, the locking of plain type back door, 90 ° of rotation reversibles etc.Electromagnetic lock mode, belong to on-mechanical linkage mode, unreliable, the impact of external environmental factor on it is larger, the high-intensity magnetic field of controller switching equipment easily disturbs electromagnetic lock, can cause misoperation, in the improper dead electricity situation of secondary power supply, chainly to be failure to actuate, operation or maintenance difficult can be caused, chain unreliable.Door latch apparatus after employing Simple rotary formula, reversible cannot be realized chain, namely shutting back door, main switch is when shifting service position onto, back door can be realized be lockable, but when opening back door, when entering service mode, the chain function preventing from driving into and operate main switch cannot be realized, there is huge potential safety hazard, chain unreliable.Door latch apparatus after 90 ° of rotation reversibles, structure is simple, and action is reversible, but there is the defects such as cabinet distortion, the dislocation of main shaft lock dog, causes chain inefficacy, the adverse consequencess such as mechanism's clamping stagnation, finally causes chain failure, poor stability, jeopardize human life.Therefore, unreasonable, irreversible, invalid backdoor interlocking device, can reduce reliability and the fail safe of switchgear, threatens personal safety.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, provides a kind of structure simple, easy to operate, greatly can improve the rear door of switch cabinet novel trans locking device of switch cubicle fail safe.
Technical scheme: in order to solve the problems of the technologies described above, a kind of rear door of switch cabinet novel trans locking device described in the utility model, it comprises the macro-axis fixed block be located on cabinet door, described macro-axis fixed block is provided with earthed switch operation macro-axis, earthed switch operation macro-axis on the right side of described macro-axis fixed block is provided with macro-axis auxiliary member, connecting pin is provided with in described macro-axis fixed block bottom, described connecting pin is provided with swinging mounting, described swinging mounting is fixed on cabinet door by rotating fixed support, catch bar is provided with in described swinging mounting bottom, described catch bar is fixed on cabinet door by catch bar support, that section of catch bar in described catch bar support is provided with spring stop piece, back-moving spring is provided with between described spring stop piece and catch bar support rear portion, link slot is provided with in described macro-axis auxiliary member bottom, described connecting pin mates with link slot and is connected, described connecting pin is provided with joint pin, lower joint pin is provided with in described catch bar rear end, joint pin groove and lower joint pin groove is respectively equipped with at the upper and lower two ends of described swinging mounting, be provided with at described swinging mounting and rotation fixed support junction and be rotationally connected post.
Described earthed switch operation macro-axis, connecting pin and catch bar be arranged in parallel between two.
Described macro-axis auxiliary member and earthed switch operate macro-axis and are fixedly connected with.
The utility model is when back door is shut, and before catch bar is pushed to, drive swinging mounting, swinging mounting drives connecting pin toward retrude again, makes connecting pin be in disconnected position, and earthed switch operation macro-axis just can carry out sub-switching operation.
The utility model is enforceable shuts ability power transmission by back door, replace original not closing the door just can the serious loophole of power transmission, solve open back door still can the problem of power transmission, enhance " five prevent " function, improve fail safe greatly in technology, in the use procedure of electric cabinet, further perfect safety work, solves root problem, product is used safer, reliably, more humane.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure is simple, easy to operate, use safety, easy to maintenance, macro-axis is operated operation associated by connecting pin and earthed switch, making only has a back door connection shuts ability power transmission, substantially increases the security performance of switch cubicle, without potential safety hazard, this product result of use is good, realistic instructions for use.
