AI Technical Summary

Benefits of technology

This technology allows for precise monitoring of electrical connections between different parts within an electric circuit while ensuring they don't get damaged due to excessive heat or other conditions that could affect their performance. It also makes testing more efficient because each part only needs one test instead of multiple tests with separate devices.

Problems solved by technology

This patented technical solution described in the patents describes different ways to measure damage from heat on electrical components like cables during use without being limited by physical space availability. These techniques involve testing each component separately before installation but they can only determine whether any one part suffers more than others. Additionally, these solutions require periodic loops resistant tests which often result in false alarms. Overall, existing methods lack precision and efficiency in identifying damaged parts within an electricity network.

Embodiment

[0023] see figure 1 , is a schematic flow chart of the method for detecting the temperature of the gas-insulated switchgear bus joint of the present invention. The temperature detection method of the gas insulated switchgear bus joint of the present invention comprises the following steps:

[0024] S101 Determine the most sensitive point of temperature rise corresponding to the surface of the busbar of the gas insulated switchgear busbar and the busbar joint;

[0025] As one of the embodiments, the finite element numerical calculation method is used to determine the most sensitive point of temperature rise corresponding to the shell surface of the gas insulated switchgear busbar and the busbar joint.

[0026] Since the hottest points reflected on the surface of the shell by joints at different positions are different, the temperature field distribution of the busbar is calculated by the finite element numerical calculation method, and the most sensitive point of the GIS secti...

Abstract

The invention provides a temperature detection method for a busbar joint of gas insulation switch equipment. The temperature detection method comprises the steps of determining the distance between a contact and an insulation spacer and the temperature rise most-sensitive point, corresponding to the busbar joint, of the shell surface of a busbar of the gas insulation switch equipment; acquiring the load current, the environment temperature and the temperature of the temperature rise most-sensitive point of the equipment busbar and the distance between the contact and the insulation spacer; obtaining the functional relationship between the joint temperature of the equipment busbar, the load current, the environment temperature and the temperature of the temperature rise most-sensitive point of the equipment busbar and the distance between the contact and the insulation spacer; detecting the temperature of the three-phase busbar joint of the equipment. By means of the temperature detection method, on-line detection of the temperature of the busbar joint of the gas insulation switch equipment can be achieved, power failure detection of a GIS is not needed, the detection result is not influenced by external environment factors, modification of the equipment structure is not needed, the safety and the feasibility are high, busbar joints of different voltage classes in a transformer substation can be detected at the same time, and detection automation can be conveniently achieved.
