Description

Detachable drop-out arrester

Technical Field

The utility model relates to the technical field of lightning arresters, in particular to a detachable drop-out lightning arrester.

Background

The detachable arrester is skillfully installed on a drop-out mechanism of the drop-out fuse after refitting the arrester, and can be conveniently detected, maintained and replaced by means of an insulating switching-off operating lever under the condition of no power failure, so that the smoothness of a circuit is ensured, the working intensity and time of electric power maintainers are greatly reduced, and the detachable arrester is particularly suitable for places which are not suitable for power failure such as post and telecommunication, airports, stations, hospitals, luxury business areas and the like. The second generation drop-out arrester has increased the disengager, when the arrester breaks down in the unusual emergence, utilizes the power frequency short-circuit current to let the disengager action, makes the automatic disconnection of disengager ground terminal, and the arrester component turns over.

A drop-out arrester as disclosed in application No. 201620706896.X, comprising: an insulator; the left end of the rain cap is connected with the upper end of the insulator, and a conductive member with a clamping groove is arranged in the rain cap; the left end of the falling device is connected with the insulator; the zinc oxide arrester main part, the upper end of zinc oxide arrester main part links to each other with the right-hand member of rain-proof cap, is equipped with fixed cover and thermal explosion type detacher on the lower extreme screw rod of zinc oxide arrester main part, and fixed cover links to each other with the right-hand member of falling the ware, and the internal thread of thermal explosion type detacher cooperatees with the lower extreme screw rod of zinc oxide arrester main part to be used for fixing fixed cover on the lower extreme screw rod of zinc oxide arrester main part. The falling device of the falling type lightning arrester is connected with the screw rod at the lower end of the zinc oxide lightning arrester main body through the fixing sleeve and the thermal explosion type detacher, does not apply pressure to the piezoresistor in the zinc oxide lightning arrester main body, and further ensures that the zinc oxide lightning arrester main body has a better lightning protection effect.

The existing drop-out arrester ensures that the zinc oxide arrester main body has a better lightning protection effect, but the existing drop-out arrester is installed by adopting the cooperation of parts such as screws, and the like, so that the disassembly is inconvenient and the time consumption is long. Therefore, we propose a detachable drop-out arrester.
