Reinforcement system for substation outlets

Abstract

The invention relates to a transformer substation outgoing line strengthening system. The transformer substation outgoing line strengthening system comprises an outgoing line wire, a jumper wire, a down lead, a lightning arrester, a voltage transformer and a connecting wire, wherein the lightning arrester and the voltage transformer are positioned below the outgoing line wire; two ends of the connecting wire are respectively connected with the lightning arrester and the voltage transformer; two ends of the jumper wire are respectively connected with the outgoing line wire; one end of the down lead is connected with the jumper wire, and the other end of the down lead is connected to the connecting wire. Due to the fact that one end of the down lead is connected with the jumper wire and the other end of the down lead is connected to the connecting wire, compared with a traditional wire connecting manner, the length of the down lead is shortened, the lateral wind pressure of the down lead is reduced, the jumper wire and the down lead are connected together as a whole body, the weight in the air is increased, and the swing amplitude of the down lead in the wind is further reduced; and moreover, the down lead is not in direct contact with the lightning arrester, the lateral wind pressure is prevented from being concentrated onto an equipment terminal, the down lead cannot be cut by a T-shaped wire clamp in a strong wind blowing process, and strand breakage of the down lead is prevented.

Description

technical field [0001] The invention relates to the technical field of substation outlets, in particular to a substation outlet reinforcement system. Background technique [0002] At present, the outgoing wires of the substation are connected to the jumper wires in the series, and the outgoing wires are directly connected to the T-shaped clamps of the arrester terminals with down-conductors. It can work normally, but in the case of a strong typhoon, the down conductor swings repeatedly due to the strong wind, the length of the down conductor is long, and the end of the down conductor keeps bending under the strong wind, which may easily cause the down conductor to break Strands and spacers are twisted and broken, and most of the broken strands occur on the terminals of the arrester. The T-shaped clamp is installed on the terminal of the arrester. The edge of the clamp is sharp. Cutting the down conductor, resulting in broken strands of the down conductor. Contents of the ...
