Intelligent miniature circuit breaker with automatic switching-on function

Abstract

The invention relates to the technical field of circuit breakers, in particular to an intelligent miniature circuit breaker with an automatic switching-on function. The intelligent miniature circuit breaker comprises a main circuit breaker body and an insulating handle, wherein the front end of the main circuit breaker body is fixedly connected with a switching-on device, the bottom end of the switching-on device is fixedly connected with the insulating handle, the insulating handle is rotatably connected with the main circuit breaker body, the switching-on device comprises a protective shell, a first motor, a first storage battery, a square column, a threaded rod and a pull rope; the protective shell is fixedly connected to the front end of the main circuit breaker body; and the first motor is fixedly connected to the inner side of the top end of the protective shell. According to the invention, as the first motor, the first storage battery, the square column, the threaded rod and the pull rope are arranged, when the main circuit breaker body needs to be switched on, a worker controls the first motor through a control switch to drive the threaded rod to rotate on the inner side of the square column, and pulls the insulating handle through the square column, so automatic switching on of the main circuit breaker body is realized; and the operation of the intelligent miniature circuit breaker is simple, and the intelligent miniature circuit breaker can be conveniently used by workers.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to an intelligent miniature circuit breaker with automatic closing function. 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 are divided into For high-voltage circuit breakers and low-voltage circuit breakers, the division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. When they It can automatically cut off the circuit in the event of serious overload, short circuit and undervoltage faults. Its function is equivalent to the combination of fuse swi...

Problems solved by technology

[0003] Most of the circuit breakers currently on the market have simple structures and single functions. Since the circuit breakers are installed at high places for use, when it is necessary to close the circuit breaker, the user needs to use a ladder or a long tool to close the circuit breaker. It is convenient for users to use. At the same time, the circuit breaker needs to press the test button once a month. Since the circuit breaker is installed at a high place, it is not convenient for the staff to use. Therefore, to solve the above problems, an automatic closing function is proposed.
