AI Technical Summary

⚠Technical Problem

Existing direct-acting PT disconnectors have poor stability in power systems and are prone to tip discharge.

⚗Method used

Design an disconnect switch including an operating rod, a conductive rod, and a transmission assembly. The conductive rod has pins at both ends and is equipped with elastic elements. The transmission assembly drives the conductive rod to move to achieve connection with a busbar or grounding bar. The elastic elements and point contact of the pins reduce the tip charge density.

🎯Benefits of technology

This improves the stability of the disconnecting switch, reduces the possibility of tip discharge, and ensures the overall safety of the switchgear.

Abstract

This utility model belongs to the field of power system technology and discloses a disconnecting switch and switchgear. The disconnecting switch is installed on the cabinet of the switchgear, which contains a busbar and a grounding bar. The disconnecting switch includes an operating rod, a conductive rod, and a transmission assembly. The operating rod slides through the cabinet, and the conductive rod slides on the inner cone of the voltage transformer. Pushing or pulling the operating rod moves the conductive rod, which in turn moves the conductive rod through the transmission assembly. This allows the conductive rod to connect with the busbar via a pin to achieve closing or with the grounding bar to achieve opening. By setting pins at both ends of the conductive rod and an elastic element between the conductive rod and the pins, the pins connect with the busbar or grounding bar under the action of the elastic element. This ensures a tight connection and also disperses the charge to reduce the charge density at the tip, thereby reducing the possibility of tip discharge and effectively improving the stability of the disconnecting switch in the power system.
