Summary of the invention
The purpose of this utility model is to provide a kind of reactive power compensator secondary terminals case maintenance protective device; this device can remind service work personnel whether circuit breaker disconnects; prevent that staff from overhauling without cut-off breaker, avoid contact security incident to occur.
For achieving the above object, the utility model adopts following technical scheme:
Secondary terminals case maintenance protective device for a kind of reactive power compensator, comprise the lead-in circuit breaker of secondary terminals case, add in lead-in circuit breaker one side the electrical accessory that is equiped with a pair of auxiliary contact, described a pair of auxiliary contact comprise a normally opened contact and a normally-closed contact, and described normally opened contact and normally-closed contact are lead-in circuit breaker often opening in the time of off-state, normally-closed contact; Described normally opened contact two ends electrically connect with two outputs of lead-in circuit breaker respectively, and are serially connected with indicator light in normally opened contact loop, and the switching of described normally opened contact and normally-closed contact is by the folding condition control of lead-in circuit breaker.
Preferably, described normally opened contact and normally-closed contact have a common node.
Preferably, described normally-closed contact loop is in off state,
Preferably, described lead-in circuit breaker is in the time of closure state, and now described normally opened contact switches to normally-closed contact.
Preferably, described electrical accessory one side is provided with the toggle switch for switching its normally opened contact and normally-closed contact, described toggle switch inserts in lead-in circuit breaker and divides, closes mechanism with the main circuit of lead-in circuit breaker and mechanically link, to realize by the folding condition control normally opened contact of lead-in circuit breaker and the switching of normally-closed contact.
Preferably, described electrical accessory one side is provided with two reference columns, and described two reference columns insert respectively in two location holes of lead-in circuit breaker, to realize the location that is connected of electrical accessory and lead-in circuit breaker.
Preferably, described two reference columns distribute along oblique diagonal angle, to improve the connective stability of electrical accessory.
The beneficial effects of the utility model are: when lead-in circuit breaker is during in closure state, indicator light circuit is connected and is lit, and parallel capacitor device can transmission operation; During due to maintenance, lead-in circuit breaker need to be disconnected, when lead-in circuit breaker is during in off-state, indicator light extinguishes because circuit disconnects, service work personnel just can overhaul, therefore this device can remind service work personnel whether lead-in circuit breaker disconnects, prevent that staff from just overhauling and cause electric shock and other safety accidents because not disconnecting lead-in circuit breaker, the security incident of avoiding getting an electric shock occurs.
