Abstract
The utility model relates to a circuit breaker with arc interrupting and quenching device, which comprises a housing, a terminal block, a switch assembly, an arc interruption cover, a static contact, a moving contact, and a L-shaped arc shield device, wherein the L-shaped arc shield device is composed of arc shields and rest plates that are arranged vertically. The arc shields can be rotated to the position between the static contact and the moving contact under the action of the moving contact, so as to interrupt arc rapidly to prevent the moving contact and the static contact from breakdown due to long-time electric arc, thereby reaching the purpose of protecting contacts.
Description
Technical field
The utility model relates to a kind of breaker structure, is meant a kind of circuit breaker with the current interruption arc-control device specifically.
Background technology
The existing circuit breaker structure generally is made up of housing, junction block, switch module, arc-extinguish chamber, fixed contact and moving contact; fixed contact is fixedly arranged on the housing; switch module is connected with moving contact and controls its opening and closing movement, is with earth leakage protective circuit breaker also to be provided with the earth leakage protective assembly.The existing circuit breaker arc extinguishing mainly relies on arc-extinguish chamber, the electric arc that produces when moving contact disconnects is entered in the arc-extinguish chamber by the run-on tab guiding, because when electric arc enters arc-extinguish chamber by the run-on tab guiding, some electric arc is in burning between moving contact and the fixed contact, and the state that is puncturing, though this moment, moving contact and fixed contact drew back a segment distance, but because electric arc is also in burning, make the state that is in conducting between moving contact and the fixed contact, reality is not blocked power supply, so after must waiting for that run-on tab is incorporated into all electric arc arc control device and extinguishes fully, power supply is blocked in the real disconnection fully of ability between moving contact and the fixed contact, particularly when circuit is short-circuited big electric current of generation, extremely strong to the damageability of moving contact and fixed contact.
The utility model content
The utility model provides a kind of circuit breaker that is provided with retaining arc plate, can block electric arc fast, avoids moving contact and fixed contact to be detained because of electric arc is long-time and punctures, and reaches the purpose of protection contact.
The utility model adopts following technical scheme:
A kind of circuit breaker with the current interruption arc-control device, comprise housing, junction block, switch module, arc-extinguish chamber, fixed contact, moving contact and " L " shape retaining arc device, described fixed contact is located on the housing, described switch module is connected with moving contact and controls its action, described " L " shape retaining arc device is articulated on the housing, should " L " shape retaining arc device constitute by mutual vertically disposed retaining arc plate and backup plate, its drive-connecting shaft is positioned at the joint portion of retaining arc plate and backup plate and vertical with the direction of motion of moving contact; Described moving contact and can drive retaining arc plate and turns between fixed contact and the moving contact between retaining arc plate and backup plate.
Fashionable when circuit breaker closing, an end of moving contact is close proximity to fixed contact, and the other end and described backup plate join, and described retaining arc plate is parallel to the direction of motion of moving contact.When opening circuit breaker, moving contact leaves fixed contact and promotes backup plate, and " L " shape retaining arc device is rotated, and retaining arc plate stretches between fixed contact and the moving contact, reaches the effect that cuts off electric arc.During the shutdown device, moving contact is towards fixed contact direction motion, and promotes retaining arc plate, and " L " shape retaining arc device is rotated, and retaining arc plate produces between fixed contact and moving contact, can not influence being connected of moving contact and fixed contact.
This " L " shape retaining arc device also is applicable to is with earth leakage protective circuit breaker, and wherein, earth leakage protective device is generally cooperatively interacted by electric leakage coil, zero sequence current mutual inductor and electric sub-member plate and this circuit breaker and forms a residual current circuit breaker.When electric leakage took place circuit, the electric leakage coil attracted iron core promotion screw-home movement that circuit breaker is disconnected.
Compare with prior art; the utility model is provided with " L " shape retaining arc device, can turn between fixed contact and the moving contact will keeping off the arc plate under the drive of moving contact, blocks electric arc fast; avoid moving contact and fixed contact to be detained and puncture, reach the purpose of protection contact because of electric arc is long-time.

Embodiment
Describe embodiment of the present utility model with reference to the accompanying drawings in detail.
The fuser belt earth leakage protective device of present embodiment as shown in Figure 1, mainly is made up of housing 1, junction block 3, switch module 2, earth leakage protective assembly 4, arc-extinguish chamber 8, fixed contact 5, moving contact 6 and " L " shape retaining arc device 7.Switch module 2 is made up of handle, handle couple axle, contact base and aluminum frame, and moving contact 6 is fixedly arranged on the contact base.Earth leakage protective assembly 4 is cooperatively interacted by electric leakage coil, zero sequence current mutual inductor and electric sub-member plate and this circuit breaker and forms a residual current circuit breaker.
" L " shape retaining arc device 7 longitudinally is articulated on the housing 1, constitutes (shown in Fig. 2-3) by orthogonal shelves arc plate 71 and backup plate 72.Fashionable when circuit breaker closing, as shown in Figure 4, backup plate 72 is positioned at the right side of moving contact 6, and shelves arc plate 71 is positioned at the inboard of moving contact 6.When opening circuit breaker, moving contact 6 moves right, and promotes backup plate 72, make 7 direction of arrow rotations as shown of " L " shape retaining arc device, retaining arc plate 71 by paper protrude outwardly to perpendicular to paper and place fixed contact 5 and moving contact 6 between, as shown in Figure 5, reach the effect that cuts off electric arc.
During the shutdown device, as shown in Figure 5, moving contact 6 is towards left movement, and promote retaining arc plate 71 and inwardly move by paper, make 7 direction of arrow rotations as shown in Figure 4 of " L " shape retaining arc device, retaining arc plate 71 produces between fixed contact 5 and moving contact 6, and backup plate 72 protrudes outwardly to state shown in Figure 4 by paper, is about to breaker closing.
Owing to adopt " L " shape retaining arc device, utilize the motion of the motion control retaining arc plate 71 of moving contact 6, promptly reach and block electric arc fast, the purpose of protection contact does not influence the folding of fixed contact 5 and moving contact 6 again, can be applicable in the various circuit breakers.
Above-mentioned is an embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all belongs to the behavior of invading the utility model protection range.
