Abstract

A pipe bus assembly hardware used in equipment room in 500kV transformer substations or transformer substations of power plants is provided, which comprises a fixing wire clip, a sliding wire clip, a shrinking wire clip, a bracket, a screen ring, an active bracket and a pipe bus. The cavity at the two ends of pipe bus is installed with terminal damp wire clip of pipe bus, through which dampers are installed. The installed dampers overlap each other by one third after extending to the middle. A nylon sleeve is installed between the base of fixing wire clip and sliding wire clip and bracket. The base and bracket are connected with each other through conductor. The utility model can reduce the breathing vibration of pipe bus and resonance frequency of pipe bus itself so as to lower noise.

Description

The pipe bus connects combination hardware fitting

Technical field

The utility model is that the equipment room pipe bus in a kind of 500KV circuit transformer station or the transformer station of power plant connects combination hardware fitting.

Background technology

The pipe bus that equipment room in existing 500KV circuit transformer station or transformer station of power plant uses connects combination hardware fitting and comprises that fixing clamper, gliding fastener, flexing line clamp, carriage, shading ring, travel(l)ing rest and pipe bus connect and compose.Because the pipe bus is a long tube, and span is big, is prone to aeolian vibration, the base of employed fixing clamper, gliding fastener only is connected by bolt with bracing frame, has the gap between base and the bracing frame, easily produces loosening phenomenon during work, be prone to aeolian vibration behind the water conservancy diversion, produce noise.

Summary of the invention

The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of working stability is provided, and a kind of 500KV-250 equipment room pipe bus that reduces the aeolian vibration of pipe bus connects combination hardware fitting.

The utility model is achieved in that and comprises that fixing clamper, gliding fastener, flexing line clamp, carriage, shading ring, travel(l)ing rest and pipe bus connect and compose; Its particular point is pipe bus bar terminal damping wire clamp to be installed, by pipe bus bar terminal damping wire clamp installation damping wire in the cavity of pipe bus both ends.

Advantage of the present utility model is, in pipe bus end cavity damping wire is installed, the resonance frequency that can reduce to manage the aeolian vibration of bus and disturb pipe bus itself.Between the base of fixing clamper, gliding fastener and bracing frame, nylon jacket is installed, base is connected by lead with bracing frame, it is compact that base is connected with bracing frame, prevented the vibration of water conservancy diversion rear support stand, and the vibration of the pipe bus that causes because of aeolian vibration, reduce noise.
