Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] see Figure 1 to Figure 6 As shown, the conductive structure of the isolating switch composed of a special-shaped aluminum tube in the present invention includes: 2 upper conductive parts 11 and 2 lower conductive parts 15. The 2 upper conductive parts 11 are connected symmetrically through the middle rotating shaft pin 12 to form an X shape ; Then 2 pieces of lower conductive parts 15 are connected to the upper conductive parts 11 respectively through connecting shaft pins 13 . A pin shaft 17 is installed at one end of the lower conductive part 15 , and an end shaft 16 is installed at the other end, and the pin shaft 17 is connected to the corresponding shaft pin 13 through two side plates 18 . In order to ensure that the connection between the upper conductive part 11 and the lower conductive part 15 can flow reliably, four copper strips 14 are used...

Abstract

The invention provides an isolation switch conducting structure formed by special-shaped aluminium tubes. The isolation switch conducting structure comprises two upper portion conductive parts and two lower portion conductive parts. The upper portion conductive parts include conductive tubes and contact pads that are installed on the conductive tubes; the two conductive tubes are symmetrically connected together through a rotating shaft pin, wherein the rotating shaft pin is in the middle of the conductive tubes, so that an X shape is formed; and connection pins are installed at the low portions of the conductive tubes. Besides, the two lower portion conductive parts are symmetrically arranged at positions, wherein the positions are below and corresponded to the upper portion conductive parts; end portion shafts are fixed at inner side ends of the two lower portion conductive parts; and pins are installed at outboard ends. And the connection pins are connected with the corresponded pins through two side plates. According to the invention, the contact pads employ a fixed contact mode with arc plane contacting; and the contact pads have simple structures and can be installed conveniently as well as the contact areas of the contacts are large. A copper belt fixed electrical connection mode is employed during the conductive connection, so that a conductive contact area is increased, current distribution is uniform and heat is radiated fast and conductive reliability is improved. Moreover, the whole conducting structure can be assembled conveniently and fast.

Description

【Technical field】 [0001] The invention relates to the technical field of high-voltage isolating switches, in particular to a moving contact part of a single-column double-arm vertical telescopic high-voltage isolating switch. 【Background technique】 [0002] With the continuous growth of my country's power system capacity and the continuous expansion of high-voltage power grids, users have higher and higher performance requirements for power equipment. As the most widely used high-voltage electrical equipment in the power system, the high-voltage AC disconnector must have a large flow capacity, less maintenance and high reliability in order to adapt to the technological progress of the modern power grid and the requirements of the development of switchgear technology. Among them, the single-column double-arm vertical telescopic outdoor high-voltage isolating switch is widely used by users because of its small footprint and strong ice-breaking ability. However, the existing s...
