Abstract
An oil-minimum power switch comprises a fixed contact, a moving contact, an outer shell, an arc extinguish chamber, an oil groove and a connecting rod transmission device connected with the moving contact. At least two sets of insulation baffles are arranged in the oil groove, transformer oil is injected in the arc extinguish chamber, wherein the volume of the transformer oil is from one tenth to one fourth that of the arc extinguish chamber, the portion between the outer shell and the arc extinguish chamber is filled with mixed gas of hydrogen and nitrogen, an open pore is formed in the outer wall of the arc extinguish chamber and provided with a cover, and the cover is connected with the connecting rod transmission device. The oil-minimum power switch is reasonable in structure, easy to use and very practical, the transformer oil and the mixed gas of the hydrogen and nitrogen are used for efficient arc extinguish, and damage to device material by the transformer oil is reduced.
Description
Technical field
The present invention relates to a kind of electric power switch apparatus.
Background technology
Electric power switch apparatus is the control assembly of power industry outbalance, is one and can makes open circuit, makes current interruptions or make its electronic component that flows to other circuit, generally comprises contact system, arc-control device and wrench device.Switch, when opening or cutting out, can make air ionization, produces electric arc, and to switch and around cause damage, so the validity of switch arc-control device is the critical component addressing this problem.Transformer oil has outstanding heat radiation and arc extinction performance, but also there is certain corrosion and combustibility, the existing switch that is provided with transformer oil arc-control device, transformer oil mass is larger, easily reveal and cause danger, there is very large potentially danger, in a lot of degree, affected the use of transformer oil.
Summary of the invention
The present invention is directed to above-mentioned deficiency, overcome the defect of prior art, a kind of few oily power switch of efficiently arc extinguishing is provided.
Technical scheme provided by the invention: a kind of few oily power switch, comprise fixed contact, moving contact, shell, arc control device, oil groove and the link gearing being connected with moving contact, wherein, at least two group insulation barriers are set in oil groove, in arc control device, inject the transformer oil of arc control device volume 1/10th to 1/4th, between shell and arc control device, be filled with the mist of hydrogen and nitrogen, on arc control device outer wall, be provided with perforate, perforate is provided with lid, and lid is connected with link gearing.
As preferably, the dimethicone that the cycloalkyl transformer foundation oil that transformer oil is 90% by weight ratio and weight ratio are 10% forms.
As preferably, in hydrogen and nitrogen mixture body, the volume ratio of hydrogen and nitrogen is 9:1-3:1.
Beneficial effect: a kind of few oily power switch provided by the invention, rational in infrastructure, be easy to use, utilize the efficient arc extinguishing of transformer oil and hydrogen-nitrogen mixture gas, the less infringement of transformer oil to device materials, very practical.
