Protection structure of intelligent switch cabinet

Abstract

The invention discloses a protection structure of an intelligent switch cabinet, which includes a bearing assembly with accommodating space, the bearing assembly includes a cabinet body and a cabinet door, and one end of the cabinet door is arranged on the cabinet body through a hinge; and a protection device, It includes a venting unit and a blocking unit, the venting unit is arranged on the top of the cabinet body of the bearing assembly, and the blocking unit is arranged on the inner side of the cabinet door of the bearing assembly; the venting unit arranged on the cabinet body and the blocking unit installed on the inside of the cabinet door can be When the switchgear leaks, the high-temperature and high-pressure gas will be quickly discharged from the top of the cabinet, so as to avoid the explosion of the switchgear and damage to the adjacent switchgear. , which effectively improves the safety performance of the intelligent switchgear, and closes the cabinet door through the self-locking component, and can fasten the cabinet door to prevent it from blowing up when the air is deflated. It is convenient and reliable to use, and is easy to promote and use.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a protective structure of an intelligent switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. [0003] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operatin...

AI Technical Summary

Problems solved by technology

[0004] During the operation of the intelligent switchgear, due to various reasons (such as short circuit, insulation aging, human error, etc.), a circuit short circuit fault occurs. Under the short circuit current of tens of thousands of amperes, high temperature and high pressure gas is produced instantly, such as high temperature and high pressure gas If it cannot be released within a short period of time in the cabinet, it will cause the switch cabinet to burst, the adjacent switch cabinet will be damaged, and personal safety will be damaged. Easy to promote and use
