DETAILED DESCRIPTION

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 to Figure 2 As shown, the static contact seat for the isolating switch includes a first panel 100, a second panel 200 arranged parallel to each other, and an insulating plate 300 connecting the first panel 100 and the second panel 200. The first panel 100, the second panel 200 and the insulating plate 300 are integrally formed.

[0017] A plurality of first outlet holes 110 are arranged longitudinally on the first panel 100. The first outlet holes 110 are through holes, with a smaller aperture on the side facing the second panel 200 and a larger aperture facing the outside. Four holes are usually provided, which are used for connecting and installing the wiring between the static contacts of the disconnector. An extension portion 130 is formed upward on the top of the first panel 100. A plurality of third outlet holes 131 are arranged in an array on the extension portion 130. The third outlet holes 131 are through holes that are uniformly arranged in front and back. Nine holes are usually arranged in an array at equal distances on the extension portion 130, which are used to increase the number of outlet holes for wiring of the static contact holder, so as to increase the functionality of the static contact holder installed on the disconnector.

[0018] The second panel 200 is also provided with a plurality of second outlet holes 210 arranged in a longitudinal direction. The second outlet holes 210 are arranged in a mirror-symmetrical manner with the first outlet holes 110 , with a smaller hole diameter on the side facing the first panel 100 and a larger hole diameter facing the outside.

[0019] To further illustrate, first mounting holes 120 are provided at the four corners of the first panel 100 ; second mounting holes 220 are provided at the four corners of the second panel 200 . The first mounting holes 120 and the second mounting holes 220 are both used for fixing the static contact seat and its connecting structure.

[0020] To further explain, a plurality of heat dissipation holes 400 are evenly distributed around the first outlet hole 110 and the second outlet hole 210 , and the heat dissipation holes 400 are used to dissipate heat from the wiring circuit and the internal structure of the static contact seat when the static contact and the moving contact are in contact and operation.

[0021] The insulating plate 300 forms a limiting column 310 at the center of one side between the first panel 100 and the second panel 200, and the limiting column 310 facilitates the installation and positioning of the static contact. The insulating plate 300 is provided with a plurality of insulating sheets 320 at equal distances in the horizontal direction on the side facing away from the first panel 100 and the second panel 200, and a plurality of base mounting holes 330 are formed on one side of the insulating sheet 320 on the insulating plate 300. The base mounting holes 330 are blind holes, and the number is 4 in a rectangular shape, which are used to fix and install the insulating plate 300 and the entire static contact seat. Since the insulating plate 300, the insulating sheet 320 and the base mounting hole 330 are an integrated design, not only can the overall installation volume of the static contact seat be reduced while ensuring the insulation effect, but also the installation surface is large, and the installation is stable and not easy to loosen.

[0022] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0023] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
