AI Technical Summary

Technical Problem

Surge arresters used in distribution cabinets are susceptible to damage from wind and sand in outdoor environments, and existing installation structures cannot effectively protect them.

Method used

A rapid retraction and deployment mechanism for surge arresters in power distribution cabinets was designed, comprising a cylindrical shell, a screw, a slide, a column shell, a threaded column, and a servo motor. The servo motor drives the screw to move the slide and column shell, thereby achieving automatic storage and protection of the surge arrester. Combined with a column clamping device and a dehumidification device, the stability and protection effect of the surge arrester are improved.

Benefits of technology

It effectively prevents surge arresters from being damaged in windy, sandy, and rainy weather, ensures the stability and normal operation of surge arresters, avoids carriage jamming and ground wire moisture, and improves the service life and protection effect of surge arresters.

Abstract

This invention discloses a rapid deployment and retraction mechanism for surge arresters in power distribution cabinets, relating to the field of surge arrester installation technology. The invention includes a cylindrical shell with a top cover fixed to its top surface. A limiting hole is formed on the top surface of the top cover. A screw is rotatably mounted through the bottom end of the cylindrical shell, and its top end is rotatably connected to the top surface of the top cover. The screw's thread groove is a non-self-locking type. A guide rod is fixed to the bottom end of the cylindrical shell. A slide is slidably mounted on the outer wall of the screw, with its inner wall meshing with the inner wall of the screw's thread groove. The inner wall of the slide is slidably connected to the outer wall of the guide rod. A ground wire is fixed through the bottom surface of the slide, and a column shell is fixed to the top surface of the slide. This invention protects the surge arrester through the cylindrical shell and automatically retracts it from the shell during windy and rainy weather, thus preventing damage from wind and sand that could cause the surge arrester to fail.
