Overheated alarm for electrical equipment heating

Abstract

The invention discloses an overheated alarm for electrical equipment heating, which comprises a fixed heat conducting bar with a connecting mechanism, wherein the fixed heat conducting bar is provided with two multilateral petaloid metal sheets; and the fixed heat conducting bar is connected to the electrical equipment through the connecting mechanism. In the invention, when the electrical arrangement temperature rises to a certain value, the fixed heat conducting bar connected with the electrical equipment thermally conducts the heat to the two metal sheets so that the two metal sheets deform from small to large, and an alarming pigment layer is shown outside because of the deformation, thereby being easily sawn.

Description

technical field [0001] The invention belongs to the technical field of equipment temperature alarm devices, in particular to an electrical equipment overheating alarm. Background technique [0002] In a wide range of power production and operation of electrical equipment, the heating phenomenon of electrical equipment is a ubiquitous physical phenomenon, especially in transmission lines, substations of various voltage levels, factories and various public service places where electricity is used. In the electrical equipment that uses electricity, the connection parts between various electrical appliances often occur due to factors such as the manufacturing process, construction and installation process of the electrical equipment, the size of the electrical load and the operating environment. Production and stable operation of equipment are major safety hazards. Every year due to electrical heating, equipment damage, interruption of power supply, and even fire accidents have ...

[0002] In the process of extensive power production and electrical equipment operation, the heating phenomenon of electrical equipment is a ubiquitous physical phenomenon, especially in transmission lines, substations of various voltage levels, factories and various public service places that use electricity. In the electrical equipment that uses electricity, the connecting parts between the various electrical appliances often generate heat due to factors such as the manufacturing process of the electrical equipment, the construction and installation process, the size of the electrical load, and the operating environment, and electrical heating is the key to electrical safety. The major safety hazards of production and stable operation of equipment. Every year, due to electrical heating, equipment damage, power interruption, and even fire accidents have caused huge losses to enterprises. How to prevent heating and find out the share of equipment early is a key issue in power production and industrial production. An important work, the commonly used prevention methods are: temperature test wax sheet method, this method is easy to fall off by itself, and when the ambient temperature is too high, it will melt by itself and cause false alarms. equipment pollution

Infrared laser temperature measurement method is expensive, not conducive to popularization and use, temperature measurement is not accurate, its own measurement has errors, the operation is technically strong, and there will be large errors if there is a slight jitter. It is relatively passive and needs to be measured on time, which is inconvenient to find problems in time.
