The rear part of the rear baffle plate in the centrally-installed switchgear is provided with a fixed plate which is integrated with the centrally-installed switchgear. The fixed plate is provided with a hole which is corresponding to an electromagnet core shaft in the electromagnetic lock. The high-voltage electric sensor is connected with the digital-type electric display. The position sensor, the digital-type electric display and the electromagnetic lock are all in electrical connected with the controller. When the controller detects signals connected by the position sensor and the high-voltage electric sensor and locking needs to be carried out, the controller controls the electromagnet core shaft in the electromagnetic lock to pop out, and then the electromagnet core shaft in the electromagnetic lock is inserted into the hole of the fixed plate which enables the rear part of the baffle plate and the centrally-installed switchgear to be integrated together, thereby enabling the rear baffle plate not to move, and locking the rear baffle plate. If a locking condition is not met, the electromagnet core shaft is in a suck-back state, and the rear baffle plate can be randomly opened.
Description
Technical field
The utility model relates to a kind of distribution technique or power distribution equipment, especially a kind of middle-placed switch cabinet valve baffle plate anti-misoperation locking device with electromagnetic lock.
Background technology
At present, along with the update year by year of substation equipment, middle-placed switch cabinet has progressively replaced traditional cabinet type, it is high that middle-placed switch cabinet has automaticity, easy to operate, the equipment interlocking advantage such as safely, but by the middle-placed switch cabinet electric shock accidents in recent years occurring, also see that this cabinet type also exists certain potential safety hazard.
In the time that middle cabinet trolley is shaken out to cabinet completely, two backboards of rear side can fall automatically in cabinet, block the charged edge of a knife, and after backboard puts down, its opener is without auto-lock function, can people for moving mechanism, baffle plate is lifted, make charged position exposed.And the general just outlet that has a power failure has a power failure, inlet wire side bus is charged all the time, if now backboard people is for opening, touches the edge of a knife, and consequence is hardly imaginable.There is no at present the anti-misoperation locking device for valve baffle plate.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of middle-placed switch cabinet valve baffle plate anti-misoperation locking device with electromagnetic lock is provided, after this device can detect middle cabinet trolley and whether all shifts out cabinet, valve, whether exposed position is charged, by little truck position and charged situation, judge whether to exist potential safety hazard, if and there is potential safety hazard, locking valve baffle plate opener, prevents that artificial unlatching from causing electric shock accidents.
For achieving the above object, the utility model adopts following technical proposals:
A kind of middle-placed switch cabinet valve baffle plate anti-misoperation locking device with electromagnetic lock, comprise the position transducer, electrification in high voltage transducer, digital electrification display and the controller that are installed on middle-placed switch cabinet side plate inwall, and be installed on electromagnetic lock on middle-placed switch cabinet backboard, in middle-placed switch cabinet, backboard rear portion is provided with the fixed head being integrated with middle-placed switch cabinet, on fixed head, offer the hole corresponding with electromagnet mandrel in electromagnetic lock, electrification in high voltage transducer is connected with digital electrification display, and position transducer, digital electrification display and electromagnetic lock are all electrically connected with controller;
When controller detects the signal that position transducer and electrification in high voltage transducer collect, while needing locking, electromagnet mandrel in controller control electromagnetic lock ejects, the hole of the fixed head that insertion baffle plate rear portion and middle-placed switch cabinet are integrated, backboard cannot move, thus locking backboard, if do not meet barring condition, electromagnet mandrel is in sucking back state, and backboard is arbitrarily opened.
In the utility model,
Electromagnetic lock: be mainly to control valve baffle plate after two of locked middle-placed switch cabinets, dolly shaken out after cabinet, backboard cannot people for opening.
Controller: detect middle cabinet trolley position, judge that whether circuit is charged, output signal, the rotation of control step motor stops.
Position transducer: for detection of little truck position, extract dolly position signalling, transfer control.
Digital electrification display: whether charged for detection of circuit, and give controller transmission equipment electriferous state.
Electrification in high voltage transducer: charged for detection of circuit, and signal is transferred to digital electrification display.
Controller, position transducer, electrification in high voltage transducer, digital electrification display and electromagnetic lock in the utility model are existing equipment, on market, all can buy.And use existing controller just can judge processing to the signal gathering.The utility model does not propose any change or amendment to software section.
In the time of equipment interruption maintenance, whether chargedly detect inlet wire outlet by electrification in high voltage transducer, and pass to digital electrification display, then by signal transfer control.
Detect little truck position by position transducer, judge whether dolly leaves cabinet, and by signal transfer control.
Controller determines that reception signal shake out cabinet when dolly, and electrification display detects in the charged situation of casing circuit, sends control signal to electromagnetic lock, controls electromagnet mandrel and ejects, and locking backboard, can not open backboard.
This device only leaves cabinet at dolly, and in the charged situation of circuit, just meeting locking backboard, in other situations, electromagnet can not move.
This device need to be installed under equipment power down mode.
In sum, this device can detect the parameters of middle-placed switch cabinet in real time, can be good at solving the potential safety hazard of middle-placed switch cabinet backboard.
The beneficial effects of the utility model are, after the utility model can detect middle cabinet trolley and whether all shifts out cabinet, valve, whether exposed position is charged, by little truck position and charged situation, judge whether to exist potential safety hazard, if and there is potential safety hazard, locking valve baffle plate opener, prevents that artificial unlatching from causing electric shock accidents.
