Field.
Background technique
Air switch also known as air-break circuit-breaker are one kind of breaker.As long as being that electric current is more than specified electricity in one kind circuit
The switch that stream will disconnect automatically.Air switch is very important a kind of electricity in low voltage power distribution network and electric drive system
Device, it integrates control and multi-protective function.In addition to it can complete contact and disjunction circuit, moreover it is possible to circuit or electrical equipment
Cause raw short circuit, heavy overload and under-voltage etc. to be protected, while can be used for infrequently starting motor.Tripping
Mode has dynamic heat, electromagnetism and compound 3 kinds of tripping.When general overload occurs for route, though overload current cannot make electromagnetic trip
Device movement, but thermal element can be made to generate certain heat, promote bimetal leaf is heated to be bent upwards, lever is pushed to make to have contact with and latch
It disengages, main contact disjunction is cut off the power.When short circuit or heavy overload electric current occur for route, short circuit current is more than instantaneous de-
Detain setting current value, magnetictrip generates sufficiently large suction, armature is attracted to and hit lever, make to have contact with rotate axle bed to
Upper rotation is disengaged with lock, is latched in three secondary main contact disjunctions under the action of reaction spring, is cut off the power.
