Abstract
The invention relates to the field of manufacturing and design of high-voltage switches and discloses an arc extinguish chamber structure for lifting an arc voltage. The structure comprises a fixed piston and a pull rod moving in an inner hole of the piston; a relative position of an air current channel is designed to realize staged blocking and opening; and simultaneously the structure has an extended moving arc contact surface, so that the variation range of an arc length is enlarged. The structure can increase the amplitude and jump of the arc voltage and fulfills the aim of enhancing the breaking direct current, the volume and the sensitive small-current breaking capacity of a circuit breaker.
Description
Technical field
The present invention relates to high-voltage switch gear manufacturing and design field, particularly a kind of arc quenching chamber structure that improves arc voltage.
Background technology
At present, in the high-voltage switch gear, its discharge capacity of gas channel in most arc-extinguishing chamber of circuit breaker and stroke, the speed of motion are proportional, and arc voltage is the stable state variation tendency, and the arc voltage amplitude is lower, and step changes not obvious.
Summary of the invention
The object of the present invention is to provide a kind of arc voltage amplitude and transition that can improve circuit breaker in interrupting process, thereby improve the arc quenching chamber structure of circuit breaker breaking direct current, capacitive and perceptual little current breaking capacity.
For achieving the above object, the technical solution used in the present invention is: comprise the quiet arc contact and be arranged on the peripheral circumferential quiet main contact of this quiet arc contact, a side relative at the quiet arc contact is provided with the lower support seat, be fixed with the piston of cylinder and air vent hole on the lower support seat, on cylinder, be set with the moving main contact that can move along cylinder, be set with pull bar hollow-core construction and that offer pull bar circular hole and slotted hole that can move along piston in the piston, moving main contact links to each other by Connection Block with pull bar, front end at pull bar is equipped with moving arcing contact, and the outside that is positioned at moving arcing contact at the front end of Connection Block is equipped with spout.
Moving arcing contact endoporus of the present invention has the contact-making surface of lengthening.
The present invention adopts the obstruction and the opening of air-flow discharge-channel stage, but and the length of lengthening moved end contact-making surface during arc burning, the arc voltage amplitude and the transition that improve circuit breaker.Be applicable to each electric pressure, be specially adapted to the occasion of primary cut-out breaking direct current, interchange capacitive and perceptual little electric current, can improve the connecting-disconnecting function of electric current effectively.
The present invention takes fire for the previous period at electric arc, stop up gas channel, when arc control device have possessed certain blow-out condition, gas channel enters open state (being that air vent hole and the pull bar circular hole that the pull bar motion is opened on the piston connected), like this when arc voltage reaches certain amplitude, produce a tangible transition, guaranteed cut-offfing of little electric current.Along with the motion of arc control device moved end (is that pull bar drives moving arcing contact and the Connection Block that is connected with it, spout moves in the endoporus of piston, meanwhile, the moving main contact that links to each other with Connection Block moves in cylinder), realize that heavily again air-flow stops up, after the of short duration motion that continues through the moved end, arc length has possessed requirement, and amplitude is to certain value, gas channel begins opening once more, and (pull bar moves, the slotted hole of pull bar goes out piston channel), the unexpected release of air-flow not only makes the arc voltage amplitude rise to new height very soon, and produced tangible transition, guaranteed that the success of big electric current is cut-off.
But---the length (length of moving arcing contact) of the contact-making surface of moved end during the lengthening arc burning, the arc root excursion of electric arc is strengthened, promptly the excursion of arc length increases.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Wherein: 1 is quiet main contact; 2 is spout; 3 is Connection Block; 4 are moving main contact; 5 is cylinder; 6 is the lower support seat; 7 is piston; 8 is pull bar; 9 is moving arcing contact (and the contact-making surface that prolongs); 10 is the quiet arc contact; 11 is air vent hole; 12 is the pull bar circular hole; 13 is slotted hole.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are described in further detail.
Referring to Fig. 1, of the present inventionly comprise quiet arc contact 10 and be arranged on this quiet arc contact 10 peripheral circumferential quiet main contacts 1, quiet arc contact 10 and quiet main contact 1 are stiff end, be provided with lower support seat 6 in quiet arc contact 10 relative sides, be fixed with the piston 7 of cylinder 5 and air vent hole 11 on the lower support seat 6, on cylinder 5, be set with the moving main contact 4 that can move along cylinder 5, be set with the pull bar 8 hollow-core construction and that offer pull bar circular hole 12 and slotted hole 13 that can move along piston 7 in the piston 7, moving main contact 4 links to each other by Connection Block 3 with pull bar 8, at the front end of pull bar 8 moving arcing contact 9 that endoporus has the lengthening contact-making surface is installed, the outside that is positioned at moving arcing contact 9 at the front end of Connection Block 3 is equipped with spout 2.
Spout 2 of the present invention is fixed on the Connection Block 3 that is connected with moving main contact 4 upper ends, piston 7 is fixed on lower support seat 6 upper ends, moving arcing contact 9 is fixed on the upper end of pull bar 8, pull bar 8 is under the drive of operating mechanism, driving the moving arcing contact 9 and Connection Block 3, the spout 2 that are connected with it simultaneously moves in the endoporus of piston, meanwhile, the moving main contact 4 that links to each other with Connection Block 3 moves in cylinder 5.
As shown in Figure 1, take fire for the previous period at electric arc, stop up gas channel, when arc control device have possessed certain blow-out condition, along with the pull bar circular hole 12 on the pull bar 8 mobile pull bar 8 to the right begins to overlap with air vent hole 11 on the piston 7, gas channel is in open state, like this when arc voltage reaches certain amplitude, produce a tangible transition, guaranteed cut-offfing of little electric current.Motion along with pull bar 8, pull bar circular hole 12 misplaces fully with air vent hole 11, again realize again that air-flow stops up, after the process of short duration motion of pull bar 8, arc length has possessed requirement, and amplitude reaches certain value, slotted hole on the pull bar 8 moves to piston 7 outer beginnings and opens, and the unexpected release of air-flow not only makes the arc voltage amplitude rise to new height very soon, and produced tangible transition, guaranteed that the success of big electric current is cut-off.Burn electric arc on quiet arc contact 10 and moving arcing contact 9 because moving arcing contact 9 has the contact-making surface of lengthening, strengthens the arc root excursion of electric arc, and promptly the excursion of arc length increases.
