A detachable rotary operation handle of a circuit breaker

Abstract

The invention discloses a detachable rotating operating handle of a circuit breaker, comprising a base and a handle connected with the base, the base is fixed on the circuit breaker and connected with the rotating member of the circuit breaker, and the base is provided with a mechanism matching protrusion The mechanism mating convex piece is detachably connected with one end of the handle through threads, the handle is provided with threads of different diameters, the other end of the handle passes through the drawer cabinet outside the circuit breaker, and the drawer cabinet is provided with a narrow slot at the position corresponding to the handle , a handle placed outside the drawer cabinet, the top is provided with a switch, the switch is electrically connected with the LED light, the LED light is arranged on the handshake, and the handshake is arranged on the handle. Through the detachable connection of the handle and the mechanism with the protruding piece, the invention avoids exposing the handle to the outside for a long time, causing accidents, and at the same time, the detachable connection of the handle saves the floor space of the circuit breaker, and the base is fixed on the On the circuit breaker, the direction of the LED light is shining on the connection between the handle and the mechanism matching the convex part, which is convenient for installation.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a detachable rotary operating handle of a circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch. Combination with overheating and underheating relays, etc. Moreover, there is generally no need to change parts after breaking the fault current. At present, it has been widely used. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according ...

AI Technical Summary

Problems solved by technology

[0003] There is an operating handle on the circuit breaker, and the control handle is turned to control the circuit breaker in the opening or closing state. The current operating handle of the circuit breaker not only increases the floor space of the circuit breaker, but also reduces the volume of the drawer cabinet loaded with the circuit breaker. Increased, and the long-term handle is outside the cabinet, resulting in many unsafe factors, very dangerous
