Temperature measuring device for main bus of metal-enclosed switch

Abstract

The invention discloses a temperature measuring device for a main bus of a metal-enclosed switch, and relates to the technical field of temperature measurement of power equipment. The temperature measuring device comprises a sleeve, an insulating boot, a temperature measuring plug and a protective cap, wherein a first conductor penetrating through the two ends of the sleeve is arranged in the sleeve, and the two ends of the first conductor are fixedly connected with the main bus and the temperature measuring plug respectively; the sleeve and the temperature measuring plug are sleeved in the insulating boot, and the insulating boot is connected with the external part in a grounding manner so as to enable the insulating boot to form a grounding layer; the temperature measuring plug comprisesa second conductor and a shell, and the second conductor is connected with the first conductor; and an intelligent temperature measuring module for measuring the temperature of the second conductor is embedded in the temperature measuring plug, and the intelligent temperature measuring module is externally connected through a wireless signal. By implementing the technical scheme, the technical problem that the temperature of the main bus in the metal-enclosed switch box body is difficult to monitor in the prior art can be effectively solved, and the online accurate monitoring of the main busof the metal-enclosed switch can be effectively realized. The temperature measuring device has the characteristics of stable and reliable structural connection, convenient installation and operation and low maintenance cost, and has an excellent application prospect.

Description

technical field [0001] The invention relates to the technical field of temperature measurement of electric power equipment, and more specifically, relates to a main busbar temperature measurement device applied to a metal-enclosed switch. Background technique [0002] Metal-enclosed switchgear is a new generation of electrical products designed and developed successfully by introducing advanced technology and in accordance with domestic rural power and domain network transformation requirements. After strict type tests and long-term operation assessments, all technical performance indicators have reached IEC298 and GB3906 standard. The metal sealed switch has the outstanding characteristics of dustproof, anti-theft and explosion-proof, small size, stable performance, not easily affected by the external environment, and no pollution. It is mainly used in various occasions such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry and texti...

Problems solved by technology

[0004] However, according to the inventor of the present application, in the process of implementing the embodiment of the present invention, it was found that the temperature measurement of the main busbar of the metal-sealed switchgear has the following technical problems: since the main busbars of the metal-sealed switchgear are all sealed inside the metal box, the main busbar As a power channel for transmitting various power distribution needs, it carries high voltage and strong current during transmission operation, so the method of embedding a temperature sensor on the main bus cannot meet the requirements of wireless signal transmission and insulation safety distance
