Abstract
The utility model discloses an interlocking device, and particularly relates to a high-pressure cabinet middle door interlocking device wich comprises an electromagnetic lock mounted on a cabinet middle door faceplate. The electromagnetic lock comprises an operating plate and a lock body, a bolt hole is arranged in the lock body, a shifting button is fixed on the operating plate, and the end portion where the shifting button and the operating plate are fixedly connected extends to be provided with a lock bolt reciprocating in the bolt hole. By the high-pressure cabinet middle door interlocking device, a middle door is ensured not to be capable of being opened when a high-pressure vacuum circuit breaker is switched on at a working position, and a high-pressure centrally-disposed cabinet is enabled to be safer in use and maintenance.
Description
Technical field
The utility model discloses a kind of interlock, door interlock in especially a kind of high-voltage board.
Background technology
In power system five is anti-to be referred to: (1) prevents from dividing by mistake, closing line breaker; (2) prevent that on-load from dividing, closing isolating switch; (3) prevent from being with cable address (closing) grounding wire (earthing switch); (4) prevent from being with ground wire power transmission, namely prevent that line with ground (earthing switch) from closing line breaker (isolating switch); (5) prevent mistakenly entering charged chamber.One of important measures that have been embodied as electric power safety production of electric "five-proof" function.Along with the development of electrical network, the continuous renewal of technology, error-proof device is updated and is perfect.The design principles of error-proof device is: all high voltage electric equipments that likely causes maloperation, all should install error-proof device and corresponding anti-error electric blocking loop.Middle of the 10KV high-voltage intermediate switch cabinet on market now, no matter line breaker is in testing position or in operating position, the middle door of high voltage mid-placed cabinet all can be opened, be actually the charged interval that has entered line breaker, as do not have machinery and electric installation preventing mistakenly entering charged chamber, will certainly bring potential safety hazard, so door design has shortcoming in protection in current middle-placed switch cabinet.Now adopt anti-phase electromagnetic door lock can effectively prevent from entering the charged interval of line breaker under breaker closing state.
Utility model content
Technical problem to be solved in the utility model is the deficiency for above-mentioned background technology, and door interlock in high-voltage board is provided.
The utility model adopts following technical scheme for realizing above-mentioned utility model object:
Door interlock in high-voltage board, comprise and be arranged on the electromagnetic lock on door face board in cabinet, described electromagnetic lock comprises operation panel and lock body, in described lock body, has keyhole, on described operation panel, be fixed with toggle, the end that toggle is fixedly connected with operation panel is extended with reciprocating locking bolt in keyhole.
Further, described toggle is rotary toggle.
Further, on described operation panel, there is unlock hole.
Further, on described operation panel, have power knob and indicator lamp, described power knob, indicator lamp all with
Circuit board in operation panel connects.
The utility model adopts technique scheme, has following beneficial effect: in while having guaranteed that high-pressure vacuum breaker closes a floodgate in operating position, can not open, make high voltage mid-placed cabinet safer in operation and maintenance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of door interlock in high-voltage board.
Fig. 2 is electromagnetic lock guidance panel schematic diagram.
Number in the figure explanation: 1, door face board in cabinet, 2, operation panel, 3, lock body, 4, keyhole, 5, toggle, 6, locking bolt, 7, unlock hole, 8, power knob, 9, indicator lamp, 10, cabinet door lock.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme of utility model is elaborated:
Door interlock in high-voltage board as shown in Figure 1, comprise and be arranged on the electromagnetic lock on door face board 1 in cabinet, electromagnetic lock comprises operation panel 2 and lock body 3, in lock body 3, have keyhole 4, on operation panel 2, be fixed with toggle 5, the end that toggle 5 is fixedly connected with operation panel is extended with at the interior reciprocating locking bolt 6 of keyhole 4.On operation panel 2, there is unlock hole 7, power knob 8 and indicator lamp 9.Power knob 8, indicator lamp 9 are all connected with the circuit board in operation panel 2.Toggle 5 is rotary toggle.
Electromagnetic lock is when having electricity, and indicator lamp 9 is bright, presses power knob 8, and electromagnetic lock is not opened; During without electricity, press power knob 8, open electromagnetic lock, press at closing time power knob 8, the electromagnetic lock that closes, can unlocking operation while having electricity.Applying to high voltage mid-placed is exactly cashier's office in a shop first to shut door in high voltage mid-placed cabinet, with cabinet door key, tighten cabinet door lock 10, with crank, vacuum circuit breaker is shaken to operating position, the operating position that vacuum circuit breaker carries is closed, the secondary power supply switch of Electromalgnetic locking mechanism closes, the closure of the operating position constant open contact by vacuum circuit breaker, travels forward locking bolt 6, and middle door is not opened when vacuum circuit breaker closes a floodgate.Otherwise vacuum circuit breaker separating brake disconnects, and with crank, vacuum circuit breaker is shaken to testing position, presses power knob 8, stirs the toggle 5 on operation panel 2, locking bolt 6 is from keyhole 4 motion release backward, and middle door is opened.While rotating toggle 5 to unlock hole 7 position, can promote locking bolt 6 and pin door in cabinets.
In sum, high-voltage board interlock described in the utility model, while having guaranteed that high-pressure vacuum breaker closes a floodgate in operating position in door can not open, make high voltage mid-placed cabinet safer in operation and maintenance.Every replacement form that is equal to that meets the utility model aim all falls into protection domain of the present utility model.
