Problems solved by technology

In this technology, the shell is connected with a bellows to play the role of axial compensation. Such a structure can meet the connection requirements in general cases, but it cannot be adjusted when there is radial deformation on both sides of the busbar, resulting in system failure. problem appear

Abstract

The invention discloses a radial compensation bus bar used for a high-voltage switch in the technical field of high-voltage electrical appliances. The radial compensation bus bar used for the high-voltage switch comprises three groups of conductive components with the same structure, connecting pieces, and two basin-type insulators, two corrugated pipes and a shell connected with the connecting pieces, wherein a first basin-type insulator and a first corrugated pipe as well as a second basin-type insulator and a second corrugated pipe are respectively arranged at the two ends of the shell fixedly; the two ends of a first conductive component, a second conductive component and a third conductive component are respectively and fixedly connected with the first basin-type insulator and the second basin-type insulator positioned at the two ends of the shell; and the conductive components are arranged in the shell in a sealing way. The radial compensation bus bar used for the high-voltage switch meets the compensation for the axial and radial deformation in gas-insulated metal-enclosed switchgear (GIS), the adjustment of an installation error and the compensation for the deformation of expansion caused by heat and contraction caused by cold of the bus bar per se, has a large compensation amount for radial deformation, and can keep high performance of the electrical appliances.

Description

technical field [0001] The invention relates to a device in the technical field of high-voltage electrical appliances, in particular to a radial compensation bus for a high-voltage switch. Background technique [0002] As a component for collecting, distributing and transmitting electric energy, the busbar is an indispensable part of high-voltage electrical products, and most of the busbars used in high-voltage electrical appliances cannot bear the stress of radial deformation, but when the high-voltage electrical products are connected Or due to the settlement of the foundation and other reasons, there is an inevitable height difference, so the radial compensation bus comes into being. [0003] After searching the prior art, it is found that the Chinese Patent Document No. CN2610476 has recorded a "busbar structure of a power conversion isolating switch", which includes a load busbar (1), a backup power supply busbar (2), a main power supply busbar (4) ), moving contact (3...
