Embodiment
Structure of the present utility model composition and connected mode is illustrated below in conjunction with accompanying drawing.
A kind of slip arc-control device of low-voltage circuit breaker, comprise the housing 1 of circuit breaker and the fixed contact 2 be arranged in housing and moving contact 3, described moving contact is rotatably connected in a rotating shaft 4 of enclosure interior setting, one end of moving contact is provided with the contact coordinated with fixed contact, and the other end is driven by the driving mechanism 6 that is connected with shift bar 5.Stirring moving contact 3 by driving mechanism makes it 4 rotate around the shaft, thus the contact controlling moving contact contacts with fixed contact or is separated.The part of described moving contact 3 between its contact with rotating shaft is connected with the housing at driving mechanism place by an extension spring 8; In the processes of moving contact 34 rotations around the shaft, when rotation is on same straight line to extension spring 8 two ends and rotating shaft, extension spring 8 is in maximum tension state, therefore, under the effect of extension spring, moving contact 3 can be crossed rapidly this intermediateness and completes with the closed of fixed contact or be separated.
Described fixed contact 2 is arranged in a chamber surrounded by dividing plate 7, dividing plate is provided with an opening 9 passed through for moving contact, the both sides of this opening are respectively equipped with a chute, be respectively provided with between insulation catch 10, a two insulation catch and connected by back-moving spring 11 in two chutes.By controlling split or the separation of two insulation catch, can fixed contact 2 be enclosed in chamber or make it to expose and contact with moving contact.The opposite face of two insulation catch is inclined-plane 12 near one end of driving mechanism, and two inclined-planes piece together a wedge-shaped slot.Described driving mechanism is provided with a voussoir 13, this voussoir can driving mechanism 6 stir moving contact make it near fixed contact time, to insert in wedge-shaped slot with driving mechanism motion thus separately two insulation catch 10; And driving mechanism stir moving contact make it away from fixed contact time, this voussoir can exit and make two catch splits under the action of the spring of insulating from wedge-shaped slot, the opening part of shutoff on dividing plate after the split of two insulation catch, keeps apart moving contact and fixed contact, thus realizes arc extinguishing.
The specific constructive form of described driving mechanism can adopt a runner, and this runner controls around a fixing central rotation by shift bar 5, while rotation, stir moving contact 3 by position outwardly.Such as, the driving lever 15 that protrudes from runner side is arranged at the position being used for stirring moving contact 3, a bar-shaped trough is set in the end of moving contact, and make this driving lever 15 be positioned at bar-shaped trough.When runner rotates, driving lever 15 can promote moving contact 3, make it 4 rotate around the shaft, thus the contact controlling moving contact contacts with fixed contact or is separated.Extension spring 8 can be connected on the housing at runner pivot position.Voussoir is then fixed on runner circumferentially, while runner rotates, drives voussoir insert or exit wedge-shaped slot.
Further, the slit that the direction along line between fixed contact and moving contact extends can also be set on the opposite face of two insulation catch, and the width of slit is less than the diameter producing electric arc between fixed contact and moving contact.When two insulation catch move between fixed contact and moving contact, force electric arc to enter slit, thus accelerate cooling and the extinguishing of electric arc.
