A High-Voltage Circuit Breaker Convenient for Wiring

Abstract

The invention relates to a high-voltage circuit breaker convenient for wiring. The high-voltage circuit breaker comprises an operating mechanism box, wiring terminals and an insulating cylinder; the insulating cylinder is installed at the upper end of the operating mechanism box; a current conductor connected with the operating mechanism box is arranged in the middle of the insulating cylinder; annular bulge structures are symmetrically arranged at the upper end and the lower end of the outer side surface of the insulating cylinder; the wiring terminals are installed at the middle part and theupper end of the side surface of the insulating cylinder; the wiring terminals communicate with the current conductor in the insulating cylinder; and each wiring terminal comprises a connecting block, a wiring board, an inserting block, an inserting connecting column, an inserting spring, an upper locking frame, a lower locking frame and a locking buckle. The problems that an existing cable is relatively complicated in operation step of connection with the terminals, low in wiring speed and easy to damage during connection, the joints of the terminals and the cable are easily loosened under the action of external power because the outer end of the cable is not protected after the wiring terminals are connected with the cable, and the like can be solved.

Description

technical field [0001] The invention relates to the field of power components, in particular to a high-voltage circuit breaker which is convenient for wiring. Background technique [0002] High-voltage circuit breakers, also known as high-voltage switches, play a control role in high-voltage circuits and are one of the important electrical components in high-voltage circuits; high-voltage circuit breakers have a fairly complete arc-extinguishing structure and sufficient current-breaking capacity. Under the action of its internal relay protection device, the high-voltage circuit breaker can quickly disconnect the circuit; the open or closed state of the high-voltage circuit breaker is controlled by its operating mechanism. [0003] When using a high-voltage circuit breaker, it is necessary to manually connect the terminal to the external cable. The existing problems in manually connecting the cable to the terminal are as follows: [0004] 1. When manually connecting the cabl...

Problems solved by technology

[0004] 1. When manually connecting the cable and the terminal, it is necessary to insert the cable into the terminal and wind it, and then use the bolt cover to reinforce and lock the terminal and the cable. This operation step is more complicated, the wiring speed is slow, and the cable It is easy to damage it due to multiple windings;

[0005] 2. After the terminal and the cable are connected, the outer end is not protected, so that the connection between the terminal and the cable is prone to loosening under the action of external power.
