Embodiment Construction

[0046] The specific implementations of the backup bus connection device and the bus system in the present invention will now be described in conjunction with the accompanying drawings.

[0047] Such as figure 1 and figure 2 As shown, it is an embodiment of the busbar system in the present invention: the busbar system includes three-phase separately arranged A-phase branch busbar 10, B-phase branch busbar 20 and C-phase branch busbar 30, and also includes the three-phase branch busbar. Each corresponds to the spare bus 50 that acts as a substitute. When a branch bus of a certain phase in the bus system cannot work due to a fault, the operator can make the corresponding spare bus 50 replace the faulty bus by operating the corresponding switch, so that the bus The system can still continue to work stably.

[0048] A-phase branch busbar 10, B-phase branch busbar 20 and C-phase branch busbar 30 all include a busbar barrel and a conductive rod 42 arranged in the busbar barrel. Th...

Abstract

The invention relates to the technical field of power systems, and provides a busbar system and a spare busbar connection device, which can solve the problem of high production cost of power station equipment in the prior art. The standby bus connection device includes a collection connection cylinder, which is formed by combining branch cylinders connected with branch buses of each phase; each branch cylinder is provided with a branch bus connection end for connecting the branch bus of the corresponding phase, And the connection end of the branch cylinder connected with the adjacent branch cylinder, one of the branch cylinders is provided with the spare bus connection end connected with the spare bus; the spare bus connection device also includes a conductive rod arranged in the collection connection cylinder, conductive The rod is used to conduct the connecting end of each branch busbar and the connecting end of the spare busbar; the connecting end of the spare busbar and the connecting end of the branch busbar are rigid connecting ends for the direct connection of the corresponding branch busbar and the busbar barrel of the spare busbar; two adjacent branch barrels The bodies are connected by flexible connecting ends formed by bellows.

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 ...
