Practical novel isolating switch

Abstract

The invention relates to the field of low-voltage isolating switches, in particular to a practical novel isolating switch, which is characterized in that a handle is in driving connection with a translation shifting block, the translation shifting block is connected with a shifting rod, the upper ends of a damping energy accumulator and an air bag component are respectively hinged with two ends of the shifting rod, and the lower ends of the damping energy accumulator and the air bag component are respectively hinged with a mechanism shell; the airbag assembly is provided with an arc extinguishing exhaust pipe; a rotating shifting block and a moving contact assembly in the monopole assembly are connected and rotate synchronously, an arc extinguishing exhaust pipe is in butt joint with a tubular air channel, a rotating handle can drive a translation shifting block to translate and the rotating shifting block to rotate at the same time, the moving contact assembly is driven to rotate when the rotating handle is rotated, and therefore contact and separation of a static contact piece and the moving contact assembly are achieved. And the air bag assembly is driven to be compressed through translation of the translation shifting block, so that the air bag assembly blows air to the contact point of the static contact piece and the moving contact assembly through the tubular air channel, and the arc is led into the arc extinguish chamber. The disconnecting switch can blow electric arc to an arc extinguish chamber, and the blowing time can be controlled in a linkage mode through switch operation.

Description

technical field [0001] The invention relates to the field of low-voltage isolating switches, in particular to a practical new isolating switch. Background technique [0002] Low-voltage isolating switches are used in low-voltage switching circuits and are the most frequently used electrical appliances in our daily life. Low-voltage isolating switches and low-voltage isolating switches can also change the operation mode of circuits. [0003] At present, the common low-current isolating switches on the market, the arc generated during opening cannot be completely absorbed by the arc-extinguishing grid of the arc-extinguishing chamber, and the remaining arcs continue to burn between the contacts, and the switching performance cannot achieve the desired effect. With the extension of the use time, the service life of the switch is shortened. SUMMARY OF THE INVENTION [0004] In order to solve the above problems, the present invention proposes a practical new isolation switch, ...
