Abstract
The utility model belongs to electric equipment field, relates to a kind of electric coding lock with self-checking function.Electric coding lock with self-checking function of the present utility model, comprise the locked loop being arranged in electric power loop, in the inner chamber of electric coding lock, be provided with a testing circuit, described testing circuit comprises switch and signal lamp, described switch and signal lamp are connected in electric power loop, and described switch is by the auxiliary contact of the operating mechanism control of circuit breaker.The utility model can show circuit breaker deciliter state, prevents misoperation.
Description
Technical field
The utility model belongs to electric equipment field, relates to a kind of electric coding lock with self-checking function.
Background technology
The electric coding lock that is applied in high voltage electric equipment anti-misoperation field is directly connected in the operation circuit of circuit breaker.Its general operation principle is: special key operates this electric coding lock under the condition of license, and the loop of electric coding lock inside comprises a pair of circuit-closing contacts, for being switched on or switched off the electric operation loop of circuit breaker.After the closing of contact of electric coding lock, circuit breaker just can carry out electronic splitting or integrating lock operation, and the splitting or integrating lock of circuit breaker is by the operating mechanism control of circuit breaker.
Before operation electric coding lock, operating personnel want clear and definite circuit breaker in which kind of state, then carry out subsequent operation.But existing electric coding lock can not be identified circuit breaker deciliter state, easily there is the situation of misoperation, threaten the safety of the person and equipment.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of electric coding lock with self-checking function that can show circuit breaker deciliter state is provided.
Electric coding lock with self-checking function of the present utility model, comprise the locked loop being arranged in electric power loop, in the inner chamber of electric coding lock, be provided with a testing circuit, described testing circuit comprises the switch and the signal lamp that are connected in electric power loop, and described switch is the auxiliary contact by circuit breaker operation mechanism control.
In described testing circuit, be also in series with the emitter that can control electric coding lock locked loop, the described electric coding lock with self-checking function comprises that is arranged on a signal receiving device in electric coding lock key, that can receive described infrared launcher signal.
On described testing circuit, be also in series with one and manually control the master switch that detects loop break-make.
The utility model has the advantage of: design separately again circuit kit in original electric coding lock inside, to show circuit breaker deciliter state, and be provided with the infrared launcher of controlling electric coding lock locked loop, stop misoperation.So just can avoid accident to occur.
Brief description of the drawings
Fig. 1 is the utility model electric coding lock operation circuit schematic diagram;
Fig. 2 is that the utility model electric coding lock detects circuit theory figure.
Embodiment
As shown in the figure, a kind of electric coding lock with self-checking function, in the inner chamber of electric coding lock 5, be provided with a testing circuit, described testing circuit comprises switch 1 and signal lamp 2, and described switch 1 and signal lamp 2 are connected in electric power loop, and described switch 1 is controlled by circuit breaker operation mechanism 6, when circuit breaker is during in closure state, circuit breaker operation mechanism 6 can drive switch 1 closure, and signal lamp 2 is bright, reminds operating personnel's circuit breaker in closure state.
Described testing circuit is also in series with the infrared launcher 3 that signal can be passed to electric coding lock key, the described electric coding lock with self-checking function comprises a signal receiving device 7 that can receive infrared launcher 3 signals, when circuit breaker is during in closure state, infrared launcher 3 sends signal, control the locked loop akinesia of electric coding lock, stop misoperation.
On described testing circuit, be also in series with a master switch 4 of manually controlling whole detection loop break-make.
Need to use self-checking function time, manual closing master switch 4, judges now that by whether signal lamp 2 is bright whether circuit breaker is in closure state, and then carries out subsequent operation.
