Abstract

The invention relates to the technical field of electric power system application equipment, in particular to an isolation switch and an electric pole assembly. The isolation switch comprises a base and a knife switch; the base is connected with a first moving contact through a first insulator, connected with a second moving contact through a second insulator, and connected with a static contact through a third insulator; the first moving contact is connected with a first wiring terminal; the second moving contact is connected with a second wiring terminal; the static contact is connected witha third wiring terminal; and the first end of the knife switch is rotationally connected with the static contact, and the second end can be closed with or separated from the first moving contact andthe second moving contact separately. The electric pole assembly comprises the isolation switch. By virtue of the isolation switch and the electric pole assembly provided by the invention, the technical problems that hanging of a grounding wire of a distribution transformer takes relatively long time, and the overhauling efficiency of the distribution transformer is lowered in the prior art are solved.

Description

technical field

[0001] The invention relates to the technical field of power system application equipment, in particular to an isolating switch and a pole assembly. Background technique

[0002] Distribution transformer, referred to as "distribution transformer", refers to a static electrical device used in power distribution system to transform AC voltage and current according to the law of electromagnetic induction and transmit AC power. China's transformer products can generally be divided into UHV (750KV and above), ultra-high voltage (500KV) transformers, 220-110KV transformers, and 35KV and below transformers according to their voltage levels. Distribution transformers usually refer to power transformers operating in the distribution network with a voltage level of 10-35KV and a capacity of 6300KVA and below to directly supply power to end users.

[0003] According to statistics, it takes about 30 minutes to 40 minutes to change the distribution transformer from the o...
