Bus system and standby bus connecting device

Abstract

The invention relates to the technical field of electric power systems, provides a bus system and a standby bus connecting device, and can solve the problem of high production cost of power station equipment in the prior art. The standby bus connecting device comprises a collecting and connecting barrel body, wherein the collecting and connecting barrel body is formed by combining branch barrel bodies which are connected by branch buses of all the phases; branch bus connecting ends used for being connected with branch buses of the corresponding phase, and the branch barrel body connecting endsconnected with the adjacent branch barrel bodies are arranged on each branch barrel body; a standby bus connecting end connected with the standby bus is arranged on one of the branch barrel bodies; the standby bus connecting device further comprises a conducting rod arranged in the collecting and connecting barrel body, and the conducting rod is used for conducting the connecting end of each branch bus and the connecting end of the standby bus; the standby bus connecting end and the branch bus connecting end are both rigid connecting ends, and are used for direct connection of bus barrels ofthe corresponding branch buses and the standby buses; and the two adjacent branch barrel bodies are connected by a flexible connecting end formed by corrugated pipes.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a busbar system and a spare busbar connection device thereof. Background technique [0002] In the high-voltage power station transmission system, the three-phase main transformer and the three-phase main bus are respectively provided with a three-phase bus and a gas-insulated metal-enclosed switchgear. If one of the three-phase main transformers bulges, then The entire main transformer needs to be shut down until the fault is repaired before it can be put into operation again. The power outage time of the entire power station is long, and the operation reliability of the power station system is low. [0003] In order to solve the problem of long power outage time and low reliability of the power station, operators in the prior art will use an auxiliary busbar in the power station, such as the patent application document with the application publication number CN106712013A ...
