Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a novel fixed circuit breaker for cubical switchboard, is including setting up handcart frame 3 on handcart bottom plate 1, and handcart bottom plate 1's upper end fixedly connected with circuit breaker 4 is equipped with fixed seat 5 of drawing forth on the circuit breaker 4, 1 lower extreme of handcart bottom plate is connected with movable pulley 2, all be equipped with contact 6 in the fixed seat 5 of drawing forth, be equipped with insulating detector 12 on handcart frame 3, be equipped with alarm 13 on handcart frame 3, be equipped with the controller on handcart frame 3, insulating detector 12 and alarm 13 all are connected with the controller electricity, and insulating detector 12 detects whether electric leakage of handcart after contact 6 of circuit breaker and the cubical switchboard static contact butt joint circular telegram, and alarm 13 sends the warning when insulating detector 12 detects handcart electric leakage and reminds operating personnel, improves the security performance of circuit breaker.

Further, the annular chamber has all been seted up in the fixed seat of drawing 5, and this annular chamber is interior all nested insulating cover 7 that has, the structure and the annular chamber looks adaptation of insulating cover 7, insulating cover 7 is nested the one end of annular chamber and is passed through insulating spring 8 and annular chamber end-to-end connection, the length of insulating cover 7 is greater than the length of annular chamber, and when the static contact butt joint of the contact 6 that impels handcart circuit breaker and fixed cubical switchboard, the mounting on the cubical switchboard promotes insulating cover 7 and contracts to the inboard, and the static contact of cubical switchboard and the contact 6 butt joint of circuit breaker 4 can be effectual seal the static contact of contact 6 and cubical switchboard, improves the security performance of circuit breaker, and insulating spring 8 promotes insulating cover 8 and pushes to outside cover contact 6 after pulling out the handcart.
