Title:
AUTOMATIC TRIPPING AND ANTI-FALLING ARRESTER AND A LIGHTNING PROTECTION AND FUSE INTEGRATED COMBINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/004244
Kind Code:
A1
Abstract:
An automatic tripping and anti-falling arrester and a lightning protection and fuse integrated combination device, wherein the arrester includes an insulator body (1), an arrester body (3) and an anti-falling member; the insulator body (1) is internally provided with a magnet adsorption surface (118); the arrester body (3) includes a disengagement unit (303) and a lightning conductor (302) arranged from top to bottom, wherein the disengagement unit (303) comprises a magnetically attracted trip module with a built-in magnet (313), the disengagement unit (303) is adsorbed on the magnet adsorption surface (118) when working; the aging of the lightning conductor (302) causes the thermal effect inside the magnetically attracted trip module, which makes the disengagement unit (303) separate from the adsorption surface of the magnet (313); the anti-falling member supports and prevents the arrester body (3) from falling when it falls from the working position. The solution uses the thermal effect generated by the magnetically attracted trip module of the disengagement unit (303) to heat the magnet (313) to make it lose the magnetic force after the aging of the lightning conductor (302), and realizes the automatic and reliable disengagement of the aging arrester and the fall prevention of the arrester after the disengagement, which ensures the safety of the power grid and facilitates the replacement of the arrester.
