A 750kV shunt reactor high-voltage outlet structure

Abstract

A 750KV shunt reactor high-voltage outlet structure is disclosed, which includes an elevating seat, L-shaped fixed blocks are fixedly installed in positions close to the two sides at the bottom of theelevating seat, the L-shaped fixed blocks are provided with a plurality of fixed holes, a plurality of supporting blocks are connected with the middle part of the elevating seat, and a plurality of wire clips are fixedly installed on the surface of the elevating seat, the inside of the wire clip is provided with a threaded groove, the inside of the threaded groove is threadably connected with a threaded pin, the end of the threaded pin is provided with a cushion block, and the top of the elevating seat is connected with an insulating paper cylinder through a fastener. The invention disclosesa 750KV shunt reactor high-voltage outlet structure, which is provided with the insulated paper cylinder, an insulated voltage-sharing ball, the elevating seat, the L-shaped fixed blocks and the support blocks, can ensure the electrical strength of the 750kV outlet line, ensure that the outlet line structure and the sleeve are installed on the oil tank body, improve the seismic resistance of the 750kV shunt reactor, and bring better application prospects.

Description

technical field [0001] The invention relates to the field of reactor outlet structures, in particular to a high-voltage outlet structure of a 750KV shunt reactor. Background technique [0002] The high-voltage outgoing line of the 750 kV ultra-high voltage shunt reactor generally adopts an indirect outgoing line structure. The high-voltage outgoing line enters the outgoing line device composed of insulating parts, copper pipes, pressure equalizing rings, etc., and then connects with the bushing terminal board. The outlet device and bushing are installed in the "elephant trunk" rising seat independent of the fuel tank. Since the reactor body acts as a shock source, the vibration is extremely large, and the high-voltage "elephant trunk" rising seat is independent of the outside of the fuel tank, which has a great impact on the fuel tank. the shearing effect. Under the vibration of the reactor body at a frequency of 100Hz, the independent "elephant trunk" rising seat creates ...

AI Technical Summary

Problems solved by technology

Under the vibration of the reactor body at a frequency of 100Hz, the independent "elephant trunk" rising seat creates a great safety hazard; at the same time, because the weight of the main body and the rising seat is not much different, the two are only connected by the flange and the reinforced iron, which is shock-resistant The ability is poor, which has brought a certain impact on people's use process. Therefore, we propose a 750KV shunt reactor high-voltage outlet structure
