An anti-seismic substation pillar equipment connection device with adjustable installation position

Abstract

The invention relates to a seismic substation support post equipment connecting device capable of adjusting an installation position. The seismic substation support post equipment connecting device is used for connecting electric equipment (1) and a support post (4), and comprises an upper metal plate (5), a lower metal plate (6) and at least four damping bolts (7), wherein the bottom ends of the damping bolts (7) are fixed to the lower metal plate (6); and the upper metal plate (5) passes through damping bolt mounting holes a (501) formed in the upper metal plate, and movably sleeves the damping bolts (7). When the seismic substation support post equipment connecting device is used, firstly, the lower metal plate (6) is connected to the top end of the support post (4); secondly, the upper metal plate (5) is connected with an electrical equipment (1) body; and finally the installation position of the electrical equipment (1) body is adjusted by adjusting the lengths of the damping bolts (7) between the upper metal plate (5) and the lower metal plate (6). Compared with the prior art, the installation accuracy of the equipment can be improved; seismic response of the equipment is reduced; and the expensive electrical equipment is protected.

Description

Technical field [0001] The invention belongs to the technical field of seismic resistance of substation equipment, and in particular relates to a seismic type substation support device connecting device with adjustable installation position. Background technique [0002] The substation is a key part of the power lifeline project. In the high-voltage substation, the structure of most equipment is porcelain or composite insulators or bushings on the upper part, and steel pillars or supporting frames at the lower part, such as circuit breakers and lightning arresters. , Capacitors, isolation switches, etc. High-voltage electrical equipment has a large mass and a high center of gravity, which is prone to damage under the action of a strong earthquake, which will lead to the paralysis or even complete collapse of the power system. The failure of the power system will cause serious disasters and huge economic losses, not only affecting the disaster relief work after the earthquake, th...

AI Technical Summary

Problems solved by technology

[0007] (1) There is no shock absorption effect in the vertical direction, and it may be damaged due to the impact of the main body of the electrical equipment 1 on the fulcrum under the action of a vertical earthquake;

[0008] (2) Since the yield strength of the lead material is very small, the long-term wind load will loosen the connection;

[0009] (3) The lead alloy damping and shock absorbing device 3 has no restoring force, and it can only perform one-way yield deformation under the action of an earthquake, so the connection tends to loosen under the action of an earthquake, and there are certain defects in use
