Problems solved by technology

In order to increase the opening speed, it is necessary to increase the stored energy of the opening spring, which will increase the output power of the operating mechanism and the mechanical strength of the whole machine, thereby greatly increasing the cost and reducing the technical and economic indicators.
At present, there is no switch product with a speed other than 0.

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention is further described by embodiment:

[0018] as attached figure 1 As shown in , the contact structure of this example includes a moving contact bridge (101), a static contact (201) and a striker (301).

[0019] One end of the moving contact bridge (101) connected to the grid line, the moving contact bridge (101) is provided with a first moving contact (102) and a second moving contact (103), and the end face of the second moving contact (102) is arc. The static contact (201) is opposite to the first movable contact (102), and is connected to the other end of the grid line. The plunger (301) is opposite to the second movable contact (103), and the end face of the plunger (301) is arc-shaped, and the mass of the plunger (301) is greater than the overall mass of the second movable contact (103).

[0020] as attached figure 2 As shown in , when the brake is opened, the plunger (301) hits the second m...

Abstract

The invention discloses a contact structure having non-0 rigid separation speed, belonging to the technical field of power electronics. The contact structure comprises a movable contact bridge; a first movable contact and a second movable contact are arranged on the movable contact bridge; the contact structure further comprises a static contact and a collision rod; the static contact is opposite to the first movable contact; and the collision rod is opposite to the second movable contact. When separating is carried out, the collision rod collides the second movable contact, so that the second movable contact has the speed and drives the movable contact bridge; and thus, the first movable contact and the static contact are rapidly separated at the non-0 rigid separation speed.

Description

technical field [0001] The invention relates to a contact structure whose rigid-point speed is not zero, and belongs to the technical field of power electronics. Background technique [0002] The contact structure is the basic structure of common switching devices. The opening time is an important parameter of the contact structure. Generally speaking, the shorter the opening time, the better. One is to quickly break the fault current; the other is to avoid arcing, or the contact is burned or even welded if the arcing time is too long . [0003] The opening time depends on the opening speed. Because the initial speed of the moving contact is 0 when the switch is in the closed state, the required speed for opening is usually defined as the average speed for a period of time (or a distance) immediately after opening. [0004] When the switching device is in the closed state, the moving contact and the static contact in the contact structure are relatively static. In the pr...
