Electric power high-voltage cabinet with overheating warning and repair assisting functions

Abstract

The invention discloses an electric power high-voltage cabinet with overheating warning and repair assisting functions, and belongs to the technical field of electric power high-voltage cabinets. Through the arrangement of a sound production warning ball, a self-adjusting driving warning ball and a heat absorption repair assisting ball, when an overheating phenomenon occurs in a cabinet body, a thermal soft fixing rod body can be heated to be softened, so that a driving and extruding elastic rope can rebound; so that the driving and extruding elastic rope is driven to upwards extrude the elastic air bag, the warning whistle makes a sound to warn, so that related workers can find the overheating phenomenon of the high-voltage switch cabinet in time, further deterioration of faults can be avoided, and loss caused by the overheating phenomenon is effectively reduced; and the heat absorption repair assisting ball can achieve a certain cooling effect on the cabinet body, temperature rise in the cabinet body is delayed, more reaction time is gained for related workers, maintenance of the high-voltage cabinet is facilitated, the sound warning ball, the self-adjusting alarm driving ball and the heat absorption repair assisting ball can be restored after maintenance is completed, functions can be triggered repeatedly, and practicability is improved.

Description

technical field [0001] The invention relates to the technical field of electric high-voltage cabinets, and more specifically, relates to an electric high-voltage cabinet with an overheating warning and maintenance assistance function. Background technique [0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. The high-voltage switchgear is an electrical product with a voltage level of 3.6kV ~ 550kV. The high-voltage switchgear should meet the relevant requirements of the "Standard for AC metal-enclosed switchgear". Components, various mechanisms, secondary terminals and wiring. [0003] The high-voltage switchgear has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. It is mainly applicable to various places such as power plants, substations, petrochemicals, metallurgical steel rolling, li...

AI Technical Summary

Problems solved by technology

[0004] During the operation of the high-voltage equipment in the high-voltage switchgear, it will generate heat due to electromagnetic action. During normal operation, its heating temperature is within the normal temperature range. , the temperature in the cabinet will be higher than the normal temperature, resulting in overheating, and with the development of the fault, the temperature in the cabinet will become higher and higher. Overheating faults may also quickly develop into serious faults, resulting in damage to the switchgear and even more serious vicious accidents
