Temperature measurement system for loop connection structure of high-voltage switchgear

Abstract

The invention discloses a temperature measurement system for a loop connection structure of a high-voltage switchgear. The temperature measurement system comprises a conductive metal element, an insulating heat conduction element, a temperature measurement guide wire and a temperature display and acquisition device. The conductive metal element is used for transmitting the temperature of the connection structure to the insulating heat conduction element, one end of the insulating heat conduction element is connected to the conductive metal element, and the other end of the insulating heat conduction element is connected to the temperature display and acquisition device through the temperature measurement guide wire. In the temperature measurement system, the temperature of the connection structure can be transmitted to the temperature measurement guide wire through the conductive metal element and the insulating heat conduction element, and the temperature measurement guide wire converts a temperature signal into an electric signal and transmits the electric signal to the temperature display and acquisition device for displaying the temperature in real time, so that a worker can monitor the temperature in real time, corresponding processing can be carried out in time when abnormal heating conditions happen, and the safety of equipment operation is improved. In addition, the insulating heat conduction element does not need to be additionally connected with a power supply, so that passive transmission of the temperature can be realized.

Description

technical field [0001] The invention relates to the technical field of high-voltage equipment, in particular to a temperature measuring system for a circuit connection structure of a high-voltage switchgear. Background technique [0002] In order to ensure the safe operation of the power system, the thermal fault diagnosis of high voltage equipment is generally paid attention to. For the circuit connection structure of high-voltage equipment, such as high-voltage switches, the contact resistance of the contacts becomes larger, overload, etc. cause the temperature of the joints to be too high, and generate heat. Accidents, resulting in greater economic losses. However, in the prior art, the abnormal heating of the circuit connection structure of the high-voltage equipment cannot be detected in time during operation, which affects the safety and reliability of the power system operation. [0003] Therefore, how to detect abnormal heating in time is a technical problem that t...
