Abstract
The utility model discloses a magnetic-quenching arc-extinguishing device with an automatic changeover switch having dual power supplies. The utility model comprises an arc-extinguishing chamber and a U-shaped iron plate, wherein two poles of the U-shaped iron plate are tightly attached to the outer side of the arc-extinguishing chamber. The utility model adds the U-shaped iron plate to the outer side of the arc-extinguishing chamber and uses magnetic-quenching principle in order to cause an electric arc to fast enter an arc-extinguishing grid sheet under the action of electromagnetic force, and thus favorable arc-extinguishing effect is obtained.
Description
Technical field
The utility model relates to a kind of arc-control device, specifically is used for the magnetic quenching device of double power supply automatic transfer switch.
Background technology
Double power supply automatic transfer switch is provided with two groups and moves, fixed contact is used for realizing automaticallying switch between two groups of power supplys, moving, fixed contact can produce electric arc when disjunction and closure, the arc-control device of double power supply automatic transfer switch of the prior art mainly is all to be provided with arc control device near two groups of contacts, as shown in Figure 1, arc control device 3 mainly are made up of arc extinguishing grid pieces, the fixed contact of stationary contact bar 1 end is positioned at arc control device 3, in order to strengthen arc quenching effect, between stationary contact bar 1 and arc control device 3, can also be provided with and lead arc plate 2, the arc-control device arc quenching effect of this structure is not fine, exists long shortcoming of quenching time.Yet the length of quenching time seems particularly important concerning double power supply automatic transfer switch, if the time that electric arc exists is oversize, not only damages contact, also might cause the short circuit between the power supply, causes bigger harm to circuit.
The utility model content
The technical problems to be solved in the utility model provides a kind of arc-control device that is used for double power supply automatic transfer switch, and its arc extinguishing ability is stronger.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of magnetic quenching device of double power supply automatic transfer switch, comprise arc control device, and also comprise the U-iron plate, the two poles of the earth of described U-iron plate are close to the outside of arc control device.
Also establish insulating barrier between the two poles of the earth of described U-iron plate and the outer wall of arc control device.
Also comprise be connected with arc control device lead the arc plate.
The utility model has increased the U-iron plate in the outside of arc control device, utilize the principle of magnetic blow-out, make the arc root that produces electric arc between the dynamic and static contact leave fixed contact as early as possible, under the effect of electromagnetic force, order about electric arc and enter arc control device fast, reach the purpose of rapid extinguish arcs, arc root because of electric arc leaves fixed contact as early as possible simultaneously, and the electrical endurance of switch is improved.
