Abstract
The utility model discloses an isolating switch and circuit breaker interlocking signal device, belonging to power system electrical equipment, which comprises an isolating switch mechanism control box and a circuit breaker mechanism control box; wherein, a signal light is arranged on the auxiliary contact of the isolating switch; a switch is arranged on the two normal open auxiliary contacts of the circuit breaker; a normal open auxiliary contact of the circuit breaker is connected with a normal open auxiliary contact of the isolating switch. The utility model has the advantages of guarding against personal injury accidents caused by misoperation of operators, reliability and stability of power system running, low investment, being easy to implement, good performance, universality in the power system, and high popularization using value.
Description
Technical field:
The utility model belongs to the electric power system electric installation, is specifically related to a kind of isolating switch and circuit breaker interlocking signal device.
Background technology:
At present, when transformer station carried out between isolating switch and the circuit breaker grid switching operation, there was a deficiency in the connection institute device of use, when promptly normally moving, whether can't detect it effective, whether it effective if detect, after bus all must being had a power failure, and electric operating disconnecting link again, confirm whether electrical interlock plays a role, if electric operating is unusual, electrical interlock complete failure during mechanically actuated operation can't realize preventing the function of on-load disconnecting switch operation.
Summary of the invention:
The utility model aims to provide a kind of above-mentioned shortcoming that overcomes, and can obviously show the isolating switch and the circuit breaker interlocking signal device of circuit breaker released state.
The realization the technical solution of the utility model is: comprise isolating switch mechanism control cabinet and breaker mechanism control cabinet, it is characterized in that on the contact of isolating switch, signal lamp being installed, on two contacts of circuit breaker switch is installed, a contact of circuit breaker is connected with a contact of isolating switch.
When breaker closing, signal lamp is bright, can intuitively point out the staff significantly: danger! Circuit breaker is an operating state, forbids the on-load disconnecting switch operation!
The personal injury accident that the utility model can avoid the staff to take place because of misoperation guarantees the reliable and stable operation of electric power system, and small investment is easily implemented, and effect is remarkable, generally is suitable in electric power system, has application value.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, isolating switch mechanism control cabinet 2, signal lamp 3, switch
4, breaker mechanism control cabinet
Embodiment:
Embodiment: shown in Figure 1, at existing GW
4Connect signal lamp 2 (signal lamp 2 can be fixedly mounted on tangible place, helps the staff and sees) with lead on two auxiliary contacts of-110 type isolating switch mechanism control cabinets 1, at SW
2Often open for two of-110 type breaker mechanism control cabinets 4 and use lead connection switch 3 on the auxiliary contact, of often opening the auxiliary contact isolating switch corresponding with it of circuit breaker often opens the auxiliary contact connection.
Illustrate: each parts of present embodiment are standarized component commonly used, and general staff all can implement the Therefore, omited pictorial diagram by Fig. 1.
