Low-voltage circuit breaking structure based on power supply of large computer

Abstract

The invention discloses a low-voltage circuit breaking structure based on a power supply of a large computer. A baffle is arranged in a shell, a first butt strap is arranged in the baffle, the baffle is provided with a contact, a first spring and the baffle are fixed to the shell, the first butt strap is in contact with a second butt strap, a connection column is fixed to the second butt strap and is provided with a contact block, the contact block is provided with two metal pieces which are fixed to the shell, the contact block is provided with an armature, an over-current trip coil, a decompression trip coil and a shunt excitation coil are arranged in the shell, close to the armature and connected with the baffle, the over-current trip coil is connected with a heating resistance wire, and the heating resistance wire is arranged in a shell cavity. The low-voltage circuit breaking system is quick in response, and a protective structure is formed in the computer so that the low-voltage circuit breaking structure can meet the requirement for conversion frequency of internal components of the large computer, safety of the components is protected and the service life is prolonged.

Description

technical field [0001] The invention relates to a structure, in particular to a low-voltage circuit breaking structure based on large computer power supply. Background technique [0002] A switch is an electronic component that can open a circuit, interrupt the current flow, or allow it to flow to other circuits. Low-voltage circuit breakers are also called automatic air switches and automatic air circuit breakers. Its function is a combination of knife switch, fuse, thermal relay, and undervoltage relay. It is often used as a main power switch for low-voltage (below 550V) power distribution. It has the function of simultaneously protecting the motor from short circuit, overcurrent, undervoltage, and voltage loss. . There are many types of low-voltage circuit breakers, which can be divided into frame type and plastic shell type according to their structure; can be divided into manual, electric and hydraulic transmission operation according to operation; can be divided into...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the problem that the structure and performance of the existing low-voltage circuit breaker cannot keep up with the conversion frequency of the internal components of the large-scale computer, the response time is too slow, the components are easily burned out, and the service life is shortened. A low-voltage circuit breaker structure based on the power supply of large-scale computers. The low-voltage circuit breaker structure responds quickly. By forming a protective structure inside the computer, it can adapt to the conversion frequency of the internal components of the large-scale computer, protect the safety of the components, prolong the service life, and solve the problem of The structure and performance of the existing low-voltage circuit breakers cannot keep up with the conversion frequency of the internal components of the large computer, and the response time is too slow, which may easily cause the components to burn out and shorten the service life.
