Embodiment Construction

[0021] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 and figure 2 As shown, a high-current switch contact suitable for high-voltage equipment includes a conductive contact body 1 and a base 2. The conductive contact body 1 surrounds and clamps the base 2 on three sides, and the conductive contact body 1 is fixed to the base 2 through a fixing device. The conductive contact 1 is in the shape of an axe.

[0023] The fixing device includes connecting bolts 3 and nuts 4. The connecting bolts 3 are connected in series with the tails on both sides of the conductive contact 1 and the base 2. The nuts 4 are locked on the connecting bolts 3, so that the connecting bolts 3 and the nuts 4 are tensioned from both sides. The conductive contact body 1 clamps the base 2 . Both ends of the connecting bolt ...

Abstract

The invention discloses a contact for a high-voltage equipment high-current switch. The contact includes a conductive contact and a base, the three sides of the conductive contact enclose and clamp the base, the conductive contact is fixed to the base via a fixing device, the conductive contact is formed by the laminated bending of a plurality of conductive strips, the front part and the tail parts at the two sides of the conductive contact are in a multi-conductive-strip hot-melting integrated structure, and the middle parts of the two sides of the conductive contact are in a multi-conductive-strip separated structure. The middle parts of the two sides of the conductive contact are in a multi-conductive-strip separated structure, the structure can maintain the characteristics of sheets to take the effect of flexible connection, so that the flexible adjustment and conductivity of the conductive contact can be guaranteed, due to the multi-sheet combination, the passage of high current cannot be influenced, the surface area is increased, and the heat dissipation is improved. The whole structure is simple and the stability is good, the contact is applied to an isolation switch to effectively reduce the temperature rising in the operation of the high-current isolation switch, so that the safety and reliability in the operation of the isolation switch can be improved.

Description

technical field [0001] The invention belongs to the field of high-voltage electric equipment, in particular to a high-current switch contact suitable for high-voltage equipment. Background technique [0002] Box-type fixed complete switchgear—XGN cabinet, as an important type of complete switchgear, is widely used in 10kV power system, and its operation reliability is directly related to the safety and stability of power system operation. The isolating switch is the main component in the XGN cabinet. It plays the role of conductive transmission of electric energy in the closed state, and undertakes the important function of safely isolating the main circuit in the maintenance state. The isolating switches used in XGN cabinets mainly include GN30 and GN22 types, among which GN30 isolating switches occupy the absolute number. [0003] In recent years, in the operation fault statistics of high-voltage switchgear, disconnector faults account for a large proportion. Quality pro...
