Abstract
The invention discloses a kind of off circuit tap changers with isolation board, including Switch main body, the Switch main body is disk-shaped structure or strip structure, static contact and the moving contact component with static contact phase configuration are provided on Switch main body, it is characterized by: being equipped with insulator spacer in the lower section of Switch main body, the insulator spacer is for the electrical body on disconnecting switch ontology.By the way that insulator spacer is arranged, can the insulation performance of electrical body over the ground on effective disconnecting switch ontology, avoid the generation of electrical body point discharge, on the one hand the safety and reliability of switch are improved, on the other hand, insulation performance improves, and is more conducive to the design of volume of transformer miniaturization.
Description
Technical field
The present invention relates to a kind of off circuit tap changers with isolation board.
Background technique
Existing distribution transformer off circuit tap changer mainly has disk-shaped structure and two kinds of strip structure, and the two is installed in
High-low pressure casing middle position between transformer box cover and body, since off circuit tap changer contact electrode shape is not advised
Then, iron core and its folder are ground electrode, and also there are many tip electrical bodies, in order to guarantee to switch insulation performance over the ground, often
Height dimension between case lid and iron core is needed to stay larger space, so that oil tank of transformer height is higher to make inside transformer fill
Oil mass is more, while making oil tank of transformer steel also more, leads to transformer manufacturing increased costs.In addition transformer size becomes
It after big, occupy installation space and also becomes larger, especially in case change, it is larger to occupy power distribution cabinet volume, so that overall cost rises.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of insulating properties in view of the deficiency of the prior art
Can be good, convenient for the off circuit tap changer with isolation board of volume of transformer miniaturization.
The technical scheme adopted by the invention is as follows: a kind of off circuit tap changer with isolation board, including Switch main body, institute
Stating Switch main body is disk-shaped structure or strip structure, and static contact and the dynamic touching with static contact phase configuration are provided on Switch main body
Head assembly, it is characterised in that: be equipped with insulator spacer in the lower section of Switch main body, the insulator spacer is used for disconnecting switch sheet
Electrical body on body.
According to the above technical scheme, the insulator spacer is isolation board, and the isolation board is parallel with the lower end of Switch main body
Setting, and set it is at regular intervals, on it be equipped with fixing terminal connect with Switch main body.
According to the above technical scheme, the upper end of the fixing terminal is equipped with connecting hole or elastic fastening hook structure, is used for and switch
Ontology is connected.
According to the above technical scheme, it when the Switch main body is disk-shaped structure, is along the circumferential direction set in the upper end of isolation board
There are multiple fixing terminals, is equipped with elastic fastening hook in the upper end of each fixing terminal, Switch main body is connected to by elastic fastening hook
In switch pedestal.
According to the above technical scheme, the isolation board is circular configuration, has a diameter larger than the outer diameter of Switch main body, and its edge
On the outside of the connecting terminal for covering static contact.
According to the above technical scheme, when the Switch main body is strip structure, the fixing terminal is vertically set on isolation
On plate, end is equipped with connecting hole on it, for being bolted with the insulating bar on Switch main body.
According to the above technical scheme, the isolation board is one or two layers and the above composite construction.
According to the above technical scheme, the isolation board is made of insulative type material.
It is obtained by the present invention to have the beneficial effect that the configuration of the present invention is simple, low manufacture cost, it is dielectrically separated from by setting
Part electrical body and body, the insulation performance of lifting switch over the ground can avoid electrical body tip from putting on effective disconnecting switch ontology
The generation of electricity, on the one hand improves the safety and reliability of switch, and on the other hand, insulation performance improves, and is more conducive to becoming
The design of depressor volume miniaturization.
