Contact with strong on-off function

A contact and capability technology, applied in electrical switches, contact materials, high-voltage air circuit breakers, etc., can solve the problems of cut-off value, voltage shock resistance, and breaking times. The electrical indicators are not ideal, shorten the life of the vacuum interrupter, and affect the Contact life and other issues, to achieve the effect of improving welding resistance and breaking capacity, reducing current density and prolonging service life

Problems solved by technology

[0002] At present, there are still some deficiencies in the contacts of the vacuum interrupter. The disadvantages are: due to the defects in structure and chemical composition, under high-voltage working conditions, there is a disadvantage of too fast welding, because the contacts stick together, It is easy to cause a short circuit. These shortcomings not only affect the life of the contacts, but also shorten the life of the vacuum interrupter at the same time. Because of its large amount, it will cause large economic losses.
In addition, it is not ideal in terms of electrical indicators such as cut-off value, voltage shock resistance, and number of breaking times.

Embodiment Construction

[0018] Below in conjunction with accompanying drawing and embodiment the present invention is further described, wherein:

[0019] in the attached figure 1 In the first embodiment shown, the The round hole of the font series is uniform Glyph series round holes.

[0020] It can be seen from the accompanying drawing that the diameters of the series of circular holes are equal in size, and the overall layout of the circular holes is uniformly distributed. glyph. Of course, it can be appropriately and reasonably changed according to design requirements.

[0021] in the attached figure 2 In the second embodiment shown, the The round hole of the font series is a gradient Glyph series round holes.

[0022] As can be seen from the accompanying drawing, the diameters of the series of circular holes are not equal. Although they are evenly distributed, the diameters of the holes gradually become larger from the inside to the outside. Of course, it can also be appropriately...

Abstract

The invention is a kind of new contact-head with strong disconnecting ability. The features are: there are a series of circular orifices which include 'windmill' pattern on the contact-head. The chemical components of the said contact-head include Cr, Cu, ferromagnetic elements, P, S. the said circle orifices are even and gradual-changing Tai Ji pattern 'windmill'. The said ferromagnetic elements are Fe or Co or Ni. The invention can increase disconnecting ability and enlarge useful life of the contact-head because of the circle orifices on the contact-head and their scientific compositions. It can also increase working efficiency and reduce production cost.

Description

technical field [0001] The invention relates to a component in an electronic device, especially a contact of a vacuum interrupter, more specifically, the invention is a new contact with strong breaking capacity, listed in the International Patent Classification Among them, the present invention is classified into the H01 category. Background technique [0002] At present, there are still some deficiencies in the contacts of the vacuum interrupter. The disadvantages are: due to the defects in structure and chemical composition, under high-voltage working conditions, there is a disadvantage of too fast welding, because the contacts stick together, It is easy to cause a short circuit. These shortcomings not only affect the life of the contacts, but also shorten the life of the vacuum interrupter at the same time. Because of its large amount, it will cause large economic losses. In addition, it is not ideal in terms of electrical indicators such as cut-off value, voltage shock ...
