Title:

BUSHINGS, SYSTEM FOR TEMPERATURE MEASUREMENT AND METHOD FOR INSTALLING MEASURING ASSEMBLY IN BUSHING IN SWITCHGEAR

Document Type and Number:

WIPO Patent Application WO/2019/157619

Kind Code:

A1

Abstract:

A bushing(100) comprises a conductor(110) and an insulating layer(120) which wraps around the conductor(110). The bushing(100) further comprises a groove(130) arranged between the conductor(110) and the insulating layer(120), and the bushing(100) also comprises a measuring assembly(140) received in the groove(130) and surrounding the conductor(110), wherein the measuring assembly(140) includes at least one measuring apparatus. Each measuring apparatus comprises a temperature sensor configured to measure a temperature of the conductor(110) and a passive wireless communication module configured to transmit the measured temperature. The temperature of the bushing(100) can be measured accurately and effectively, thereby improving the reliability and safety of the bushing(100) as well as the electrical device such as switchgear.
