Abstract

The invention discloses a sealed compact-type combined electrical apparatus, comprising a sealed breaker unit, a disconnector unit, a current transformer unit, an earthed switch unit and an operation mechanism. The breaker unit, the disconnector unit, the current transformer unit, the earthed switch unit and the operation mechanism are assembled on the same framework; the primary conductive part of the breaker unit is combined with the primary conductive movable end of the disconnector unit in a sealed insulation manner; the primary conductive static end of the disconnector unit is separately mounted on the framework; the movable end and static end of the disconnector unit form insulation intervals; one end of the current transformer unit is mounted on a sealed pole of the breaker unit and the other end of the current transformer unit is integrally combined with an earthed static contact. The sealed compact-type combined electrical apparatus has the advantages of clear and compact structure, reasonable operation, small mounting volume, favorable safety performance, high reliability and long repair period. Besides, the electrical performance of each unit can be coordinated and matched favorably within a limited framework space.

Description

Technical field [0001] The invention relates to the technical field of high-voltage electrical appliances, in particular to a solid-sealed compact high-voltage combined electrical appliance. Background technique [0002] Combined electrical appliances are devices that combine two or more high-voltage electrical appliances into a whole according to the main wiring requirements of the power system, while the electrical appliances still maintain the original specified performance. It has the characteristics of compact structure, small appearance and installation size, easy to use, and the performance of various electrical appliances can be better coordinated. [0003] Combination appliances popular in the market are divided into two types: open type and fully enclosed type according to the insulation structure. The open type is to connect and combine the components according to the electrical wiring requirements, and there is no special sealing and isolation between the components. ...
