Abstract
The utility model relates to the technical field of inflatable cabinets, in particular to an inflatable cabinet switch arc-extinguishing grid which comprises an installation seat and a plurality of arc-extinguishing films; the arc-extinguishing films are arranged on the installation seat; each arc-extinguishing film is provided with two side arms; the distance L between the side walls of the arc-extinguishing film is open distance; and the open distance of the arc-extinguishing film on the installation seat which is far away from a contact joint is bigger than the open distance of the arc-extinguishing film which is close to the contact joint. The arc-extinguishing film with big open distance and the arc-extinguishing film with small open distance are reasonably matched when in use, so that when a switch contact is just separated, produced electric arcs are quite concentrated; at this time, the arc-extinguishing film with smaller open distance can well attract the electric arcs so as to achieve the arc-extinguishing effect; after the contact is separated for a distance, the electric arcs are gradually cracked and radiated and exceed the best arc-extinguishing scope of the arc-extinguishing grid with small open distance; and at this time, the arc-extinguishing film with big open distance is adopted, so that the arc-extinguishing effect is improved.
Description
Technical field
The utility model relates to inflation cabinet technical field, particularly a kind of inflation cabinet switch arc-chute.
Background technology
At present, various inflation cabinet on-load switches all are provided with arc control device usually and extinguish the electric arc that produces between the dynamic and static electric shock in the switching manipulation, to guarantee electric equipment operation safety, normally adopt arc quenching chamber structure in the prior art with arc-chute, existing arc-chute comprises mount pad and several arc quenching plates, opening of arc quenching plate apart from identical, but the arc quenching effect of this arc-chute still is not ideal enough.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of arc quenching effect more desirable inflation cabinet switch arc-chute.
The utility model solves its technical scheme: a kind of inflation cabinet switch arc-chute, comprise mount pad and several arc quenching plates, arc quenching plate is installed on the mount pad, have two side arms on the arc quenching plate, distance L between the side arm of arc quenching plate is for opening distance, the opening apart from greater than the distance of opening near the arc quenching plate of contact joint away from the arc quenching plate of contact joint on the mount pad.
The quantity of the arc quenching plate of large opening and the ratio of quantity of opening the arc quenching plate of distance for a short time are 0.5.
Opening of the arc quenching plate of large opening apart from being 50mm, quantity is 3, and the distance of opening of opening the arc quenching plate of distance for a short time is 30mm, and quantity is 6.
Effective effect of the present utility model is: the distance of opening of all arc quenching plates on the mount pad of design was identical all in the past, use through actual, find that arc quenching effect still is not ideal enough, now change the large opening arc quenching plate into and open apart from the reasonably combined use of arc quenching plate for a short time, when the contact of switch has just separated, the electric arc that produces is comparatively concentrated, the at this moment for a short time arc quenching plate of opening distance can well attract electric arc, reach the effect of arc extinguishing, separately behind the segment distance, electric arc divides gradually to be dispersed, and exceeds the best arc extinguishing scope of the arc-chute of opening distance for a short time to contact, at this moment adopt the arc quenching plate of large opening, arc quenching effect is improved.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is a structural representation of opening the arc quenching plate of distance for a short time;
Fig. 4 is the structural representation of the arc quenching plate of large opening;
Among the figure, 1. mount pad, 2. arc quenching plate, 3. side arm.
Embodiment
As shown in Figure 1, a kind of inflation cabinet switch arc-chute, comprise mount pad 1 and several arc quenching plates 2, arc quenching plate 2 is installed on the mount pad 1, have two side arms 3 on the arc quenching plate 2, distance L between the side arm 3 of arc quenching plate 2 is for opening distance, the opening apart from greater than the distance of opening near the arc quenching plate 2 of contact joint away from the arc quenching plate 2 of contact joint on the mount pad 1.
The quantity of the arc quenching plate 2 of large opening and the ratio of quantity of opening the arc quenching plate 2 of distance for a short time are 0.5.
Opening of the arc quenching plate 2 of large opening apart from being 50mm, quantity is 3, and the distance of opening of opening the arc quenching plate 2 of distance for a short time is 30mm, and quantity is 6.
