Description
Technical field
The utility model relates to a kind of permanent magnetic actuator vacuum circuit breaker.
Background technology
It is strong that spring energy-storage machinery operating mechanism vacuum circuit-breaker has breaking capacity, and the life-span is long, and volume is little, in light weight, advantage such as electric arc does not expose, and is safe and reliable, be as the first-selected element of coal industry feeding switch, obtained extensive promotion and application, in the national economic development, bringing into play enormous function.But spring energy-storage machinery operating mechanism job failure rate is big.For many years traditional operating mechanism is updated, done a large amount of work, though failure rate descends to some extent, because the transmission principle of mechanism is not obtained great breakthrough, unfailing performance still can not make us pleasing oneself.Compare with spring energy-storage machinery operating mechanism vacuum circuit-breaker, permanent-magnet manipulating mechanism has adopted a kind of brand-new operation principle and structure, has the incomparable unique distinction of other technology, has fundamentally overcome the intrinsic drawback of other technology; Main motion parts has only one during work, need not transmission mechanisms such as loaded down with trivial details connecting rod, motor and take off, locker, the source of trouble is little, has suitable reliability.The vacuum circuit-breaker mechanism life-span of joining permanent-magnet manipulating mechanism is up to more than 100,000 times, and the life-span of spring energy-storage machinery operating mechanism vacuum circuit-breaker machinery has only 10,000 times.In current social reliability and life-span is the leading indicator that each producer and user pursue.Have These characteristics just because of permanent-magnet manipulating mechanism, many circuit breakers manufacturing commercial city is focused in the development of permanent-magnet manipulating mechanism both at home and abroad.
Summary of the invention
The purpose of this utility model provides a kind of permanent magnetic actuator vacuum circuit breaker, and it is few that it has a moving component, need not transmission mechanisms such as cumbersome connecting rod, motor and take off, the device of snap close, the source of trouble is little.
The utility model is achieved like this, it comprises that driver, permanent-magnet manipulating mechanism, hand close mechanism, hand sub-agencies, deciliter arm and actuating arm, insulator, lower conducting plate, go up conductive plate, vacuum tube.It is characterized in that permanent-magnet manipulating mechanism connects the actuating arm that main shaft diameter makes progress, deciliter arm that transmission main shaft directly makes progress, deciliter arm connects insulator and vacuum tube, conductive plate and lower conducting plate are equipped with in the vacuum tube two ends, permanent-magnet manipulating mechanism is made up of switching winding, closing coil, permanent magnet, moving magnetic core, to two ends bar is arranged all in moving core axis, lay permanent magnet on every side, permanent magnet is laid switching winding and closing coil up and down ...By the supply voltage in the working line, electric current driver is sent signal, send instruction through driver again, make branch, closing coil produce magnetic field.Under the effect of electromagnetic field, moving magnetic core moves up and down, and moving bar swings up and down the actuating arm, makes that a deciliter arm also swings up and down, thereby makes the vacuum tube opening and closing.The hand sub-agencies comprises that hand divides button, hand sub lever, hasp, hand divide snap close is housed on the camshaft, hand divides cam, anti-back gear, spring.Hand divides button to connect the hand sub lever, the hand sub lever connects hasp, snapping under the effect of spring tight hook lock buckles, when divide button by setting about, hasp and snap close are thrown off, and hand divides camshaft to rotate under spring action, drives the cam revolution, hand divides cam to promote the motion of actuating arm, thereby makes the vacuum circuit-breaker separating brake.Simultaneously, the spring on the hand sub-agencies has connected a hand again and has closed mechanism, and hand closes the principle of mechanism, the same with hand sub-agencies principle, rotate hand and close camshaft, close at hand under the effect of cam and spring, oppositely promote moving bar, make the actuating arm do counter motion, to reach the purpose that hand closes.So both kept coal industry that vacuum circuit-breaker is used the operation with traditional habit, and, can manually divide, close a floodgate to solve in outage or other to take place in emergency circumstances.
Entire mechanism is installed on the frame of a general frame or composite frame structure.
The utility model has the advantages that: (1) adopts permanent-magnet manipulating mechanism, and moving component has only one, need not transmission mechanism such as loaded down with trivial details connecting rod, motor and take off, the device of snap close, the source of trouble is little; (2) has higher reliability and have the controlled characteristic of electrical quantity; (3) vacuum circuit-breaker high life.
