Efficient and safe tubular bus static contact

Abstract

The invention discloses an efficient and safe tubular bus static contact. The invention relates to power equipment, in particular to an efficient and safe tubular bus static contact. The invention provides an efficient and safe tubular bus static contact which is simple in structure and ensures safe transmission of current. When the efficient and safe tubular bus static contact in operation, a tubular bus is connected in two bus holding clamps, a copper pipe is connected in two copper pipe holding clamps, the bottoms of the bus holding clamps are provided with the symmetrically arranged sinking holes, upper counter bores are symmetrically formed in the tops of the copper pipe holding clamps, the two ends of a semicircular wire in the annular wire coil can be welded into the lower counter bores and the upper counter bores conveniently, the bus holding clamps, the annular wire coils and the copper pipe holding clamps form a whole, and current transmission can be effectively guaranteed (meanwhile, no contact resistance exists). Four aluminum alloy semicircular wires are arranged, so that the rigidity and the damping performance of the static contact of the tubular bus are ensured; andtherefore, the operation of the switch equipment can be efficiently and safely ensured, and the safe operation of power transmission and transformation is ensured. The efficient and safe tubular busstatic contact is convenient to machine and reliable to operate.

Description

technical field [0001] The invention relates to power equipment, in particular to a high-efficiency and safe static contact for pipe busbars. Background technique [0002] The static contact of the tube bus is the key component of the high-voltage power transmission and transformation switch. The high-voltage switch is turned on and off by it. Its service life determines the life of the high-voltage switch, and then determines the safe operation of the high-voltage power transmission and transformation network. [0003] When the static contact is working, it relies on its own rigidity to generate a pressing force on the moving contact. Therefore, in addition to requiring high electrical conductivity, the static contact parts also require high strength and rigidity. With the improvement of the voltage level of power transmission and transformation lines and the increase of transmission capacity, the traditional forming process of high-voltage switch contact parts can no longe...

AI Technical Summary

Problems solved by technology

With the increase of the voltage level of power transmission and transformation lines and the increase of transmission capacity, the traditional forming process of high-voltage switch contact parts can no longer meet the performance requirements of the high-voltage switch industry.

The original flexible damping adopts parallel groove method to connect the wires, the contact resistance is large, the power loss is also large, and the contact point is easy to generate heat due to poor contact, which reduces the service life and reliability
