Sliding fitting for electric equipment

Abstract

The invention discloses a sliding fitting for electric equipment. The sliding fitting comprises a bracket for connecting a pipe bus and a connecting plate for connecting electric equipment; landing legs are arranged at the lower end of the bracket, a supporting shaft is arranged in each landing leg, and the supporting shaft penetrates a supporting plate; the supporting plate is fixed on the connecting plate, a sliding slot is formed in the supporting plate, and the supporting shaft penetrates in the sliding slot and capable of sliding along the sliding slot, wherein the sliding slot is a circular arc. The sliding fitting can well displace and slide under the seismic effect so as to balance the height difference caused by equipment deformation in a loop system, thereby reducing the bad influence on the electric equipment by the seismic effect; the structure system of the electric equipment is protected, the safety running of a power grid system is maintained, and the anti-seismic property of the electric equipment is improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment fittings, in particular to a sliding fitting for electrical equipment. Background technique [0002] In previous major earthquakes, the damage to the power system caused heavy losses to the national economy of our country. The survey found that the electrical equipment damaged in the Wenchuan earthquake, Yushu earthquake and Tangshan earthquake were mainly high-voltage equipment containing large porcelain bushings, including lightning arresters and circuit breakers. , isolating switch, voltage transformer and current transformer, etc. [0003] Substation pillar electrical equipment has the characteristics of "thin, high, soft, and heavy", and most of this type of equipment is composed of brittle ceramic materials. Insufficient and broken. At present, although some equipment uses composite materials with high failure stress, composite materials are more flexible than ceramic material...

AI Technical Summary

Problems solved by technology

[0007] 1. The length of the sliding groove of the existing sliding fittings is too small, and the top displacement response of the high-voltage electrical equipment under the action of the earthquake is relatively large, and it is easy to collide with the sliding groove during the sliding process, thereby increasing the seismic response of the electrical equipment. Adverse situation

[0008] 2. The sliding groove of the existing sliding fittings is a straight track, and the electrical equipment is bent and deformed after being subjected to an earthquake, and the height of the equipment will change. At this time, the sliding of the sliding fittings will be hindered
