Abstract
The invention discloses a low-voltage vacuum contactor with a breaking spring and a working method. The process requirement is very high when a vacuum arc-extinguishing chamber of the contactor is manufactured, and the vacuum degree of the arc-extinguishing chamber easily declines if the process is poor; and if the quality of the contact material is low, a 'cut-off overvoltage' phenomenon occurs when current is broken, i.e., the arc-extinguishing capability of the vacuum arc-extinguishing chamber is very strong when current is broken. The low-voltage vacuum contactor with a breaking spring comprises an upper leading-out copper bar (1), the upper leading-out copper bar is connected with a glass shell (16) via an upper supporting rod, the glass shell is connected with a contact spring (6) via a lower supporting rod, the contact spring is connected with an insulator (5), the insulator is connected with a connecting rod (12) via a fixed rotating shaft (13), and the breaking spring (7) is arranged on the connecting rod. The low-voltage vacuum contactor is applied to coal mines, chemical industry, metallurgy, cement and the like.

Beneficial effects of the present invention:
1. contact material of the present invention is generally made with alloys such as copper, antimony, bismuths.The effect of arc-chutes inner shield is, when breaking current, condenses the metal vapors diffused out in contact gap, contributes to blow-out, it is also possible to prevent metal vapors from splashing to and reduce its dielectric strength on insulation crust.Moving contact is connected with shell lower end corrugated tube, and moving contact can move up and down and will not leak gas.
Vacuum contactor arc-rupturing capacity of the present invention is strong, good pressure-resistant performance, operation frequency compared with high, life-span length, without spray outside electric arc, volume is little, lightweight, maintenance cycle is longer, suitable in 660 volts and above circuit, as having explosion-proof, anticorrosion and fire protection requirement and the more severe place of environment for industries such as colliery, chemical industry, metallurgy, cement.High-pressure vacuum contactor is also used in electric arc furnace, high-tension motor even load to make on and off switch
3. the shell useable glass of vacuum interrupter of the present invention or ceramic insulating material are made, and internal vacuum is generally more than 10 handkerchiefs.Due to the little air in shell, clearance between open contacts can be made very small, and electric arc is relatively easy to and is off.
