The invention discloses a novel contact arc-extinguishing system of a moulded case circuit breaker, belonging to the field of low-voltage electrics. The upper part of the front wall of an arc-extinguishing chamber is provided with a front air outlet, and the rear wall of the arc-extinguishing chamber is not provided with an opening; the rear lower part inside the inner cavity of the arc-extinguishing chamber is provided with a rotating shaft; a moving contact is positioned between the rotating shaft and a grating sheet; the lower end of the moving contact is connected with the rotating shaft, and the moving contact can conduct rotary motion between the front wall and the rear wall of the arc-extinguishing chamber; the arc striking sheet of the moving contact extends into the inner cavity of the arc-extinguishing chamber from outside to inside from the lower part of the front wall of the arc-extinguishing chamber and extends upwards to a position close to the front air outlet along the front wall of the arc-extinguishing chamber. According to the invention, when the moving contact excludes a limit position, the upper end of the moving contact is close to the moving contact without contacting with the upper end of the arc striking sheet of the moving contact, therefore an arc root can shift to the arc striking sheet of the moving contact during the exclusion of the moving contact so as to fast enter the arc-extinguishing chamber; and the arc-extinguishing chamber is only provided with the front air outlet, so that arc extinction can be carried out by sufficiently utilizing air blast and the problem that a plasma gas is backwards jetted is solved, therefore the on-off property of a breaker is enhanced.
Description
Technical field
The present invention relates to a kind of breaker of plastic casing, be specifically related to the contact arc-extinguishing system of breaker of plastic casing, belong to the low-voltage electrical technical field.
Background technology
Breaker of plastic casing is comprised of dynamic/static contact; can produce electric arc between dynamic/static contact after the circuit breaker break-make; if to not protection of contact; electric arc arc root will rest on the contact; the contact attenuation that can under the erosion of electric arc, diminish; finally cause the circuit breaker phase of breaking, so when the design circuit breaker, all adopt various measures and protect as far as possible the contact.Wherein increasing arc striking piece and make it attract fast electric arc, is to reduce electric arc to one of method of contact erosion.
Existing breaker of plastic casing increases the fixed contact arc striking piece around its fixed contact can easily shift electric arc arc root; like this after dynamic/static contact is scolded out; electric arc arc root can be transferred on the fixed contact arc striking piece from fixed contact; form the successively current circuit of end of incoming cables, fixed contact arc striking piece, arc extinguishing grid pieces, moving contact, thereby protection fixed contact contact is not by arc erosion.But the moving contact arc striking piece is owing to the many reasons such as the structure electric arc of failing effectively to attract, cause the moving contact arc striking piece to be equivalent to an arc extinguishing grid pieces, only play the effect of subdividing the arc, electric arc still can ablate moving contact contact or moving contact arc angle affect circuit breaker and divide the temperature rise of having no progeny and the use of circuit breaker.
The arc control device of existing breaker of plastic casing generally all are comprised of arc extinguishing grid pieces and gas exhausted material, when gas exhausted material cut-offs at circuit breaker, can produce gas under the erosion of electric arc, cooling electric arc.In the process of gas front gas outlet motion towards arc control device, electric arc is blowed to grid sheet direction, but because an opening that provides moving contact to enter the arc control device motion is provided at the arc control device rear portion, in the process of gas blast arc-quenching, the gas of some can spray towards this rear aperture direction, cause the decline of whole arc control device blast pressure, weakened the air-blowing effect, be unfavorable for improving the arc extinction performance of circuit breaker.And when gas sprays towards the rear portion opening, the plasma gas that can be inconjunction with the containing metal particle of electrical arc erosion contact, the generation of grid sheet spreads to the arc control device rear together, make these particles stick to the release zone of whole circuit breaker, cause the phase insulation decreasing insulating, and then make circuit breaker easily by over-voltage breakdown.
Summary of the invention
For the problems referred to above, the invention provides a kind of novel contact arc-extinguishing system of breaker of plastic casing, when keeping the fixed contact arc striking piece, can effectively attract the electric arc on the moving contact; And the effect that can take full advantage of gas blast arc-quenching improves interrupting performance, solves that plasma gas sprays backward and the problem that causes the release region insulation to descend.
The technical solution used in the present invention is: comprise moving contact, fixed contact, some grid sheets in arc control device and the inner chamber thereof, the grid sheet is positioned at arc control device inner chamber top, and the place, antetheca top of arc control device has on front gas outlet, the rear wall and do not establish opening; The posterior portion is provided with rotating shaft in the arc control device inner chamber, is moving contact between rotating shaft and the grid sheet, and moving contact lower end connection rotating shaft and moving contact can rotate between arc control device antetheca and rear wall around the shaft; The moving contact arc striking piece stretches in the arc control device inner chamber and extends upwardly near place, front gas outlet along the antetheca of arc control device from arc control device antetheca bottom ecto-entad; Moving contact when scolding out extreme position, moving contact upper end near but do not contact moving contact arc striking piece upper end.
Further, fixed contact of the present invention rear wall along arc control device in the arc control device inner chamber extends upwardly to the At The Height consistent with grid sheet rear portion, the upper part of fixed contact is the fixed contact arc striking piece, the mid portion of fixed contact is fixedly connected with fixed contact, and the grid sheet is between moving contact arc striking piece upper end and fixed contact arc striking piece.
The invention has the beneficial effects as follows:
1, moving contact electric arc arc root when scolding out can be transferred to like a cork on the moving contact arc striking piece and then enter rapidly arc control device; electric arc on the fixed contact can be transferred on the fixed contact arc striking piece; can effectively protect like this contact contact not by the electric arc Eroded, guarantee the performance of circuit breaker.
2, whole arc control device only are provided with front gas outlet, not needing to arrange the rear portion provides movable contact cephalomotor opening, can take full advantage of like this gas blast arc-quenching and solve that plasma gas sprays backward and the problem that causes the release region insulation to descend, improve the break performance of circuit breaker.
What 3, the moving contact arc striking piece adopted is simple in structure, is convenient to processing and installs.
4, be an overall structure after contact and arc control device install among the present invention, like this can be so that whole circuit breaker of the last assembling of workman.
5, the present invention's easy realization simple in structure, easy for installation.
