specific Embodiment 1

[0042]The voltage level of the gas-insulated metal-enclosed switchgear in this embodiment is 800 kV. The present invention mainly improves the busbar supporting device of the gas-insulated metal-enclosed switchgear, and the structure of the rest will not be described in detail.

[0043] Such as Figure 1 to Figure 4 As shown, the gas-insulated metal-enclosed switchgear includes a busbar barrel 1, and a busbar for power transmission is arranged inside the busbar barrel 1. The busbar barrel 1 is supported by a busbar support device. Insulated rolling parts, in this embodiment, roller 3 is selected as the insulating rolling parts.

[0044] The support frame 2 includes a base 21 and a bracket 22 arranged on the base 21. There are two brackets 22 and the two brackets 22 are spaced apart from each other. The left and right positions of the two brackets 22 are adjustable. By adjusting the left and right positions of the brackets 22, the positions where the two rollers 3 cooperate w...

specific Embodiment 2

[0056] Specific embodiment 2 of the gas-insulated metal-enclosed switchgear of the present invention. The difference between the gas-insulated metal-enclosed switchgear in this embodiment and the above-mentioned specific embodiments is only that in this embodiment, an external tool is applied to the bracket to make the bracket left and right. move.

[0057] In other embodiments, the left and right positions between the bracket and the base can be adjusted through a rack and pinion mechanism; in other embodiments, the height of the bus barrel can be adjusted only by adding backing plates between the bracket and the base.

[0058] In other embodiments, only one left and right position of the two brackets can be adjusted.

[0059] In other embodiments, two screw threads with opposite directions are provided at both ends of the screw rod, and the distance between the two brackets is adjusted by screwing the screw rod. In other embodiments, the two brackets can be guided and slida...

specific Embodiment 3

[0060] Specific embodiment 3 of the gas-insulated metal-enclosed switchgear of the present invention, the difference between the gas-insulated metal-enclosed switchgear in this embodiment and the above-mentioned specific embodiments is only that the dial in this embodiment is set on the bracket, and the rotating shaft of the roller is set Hands adapted to the dial.

Abstract

The invention relates to a gas-insulated metal-enclosed switchgear and a bus support device. The bus support device comprises a supporting frame and two insulating rolling pieces, the two insulating rolling pieces are arranged left and right in a spaced mode and rotationally arranged on the supporting frame, and the outer circumferential faces of the insulating rolling pieces are used for supporting a bus cylinder. A limiting piece is detachably and fixedly arranged on the supporting frame and used for being spaced from the bus cylinder and limiting the bus cylinder from being separated from the insulating rolling pieces. And the two insulating rolling pieces and the bus cylinder are arranged in a triangular shape, so that the stability is better. When the bus cylinder moves, the insulating rolling pieces rotate under the action of friction force of the insulating rolling pieces and the bus cylinder, the bus cylinder is not prone to clamping stagnation, resistance is small, the bus cylinder is not prone to clamping stagnation through rolling of the insulating rolling pieces, and large deflection of the bus cylinder can be prevented under the action of the limiting piece. The problem that a sliding block of an existing bus support device is prone to clamping stagnation, normal movement of a bus cylinder is affected, and then a bus cylinder weld joint is prone to cracking is solved.

Description

technical field [0001] The invention relates to a gas-insulated metal-enclosed switchgear and a bus bar supporting device. Background technique [0002] In the ultra-high voltage GIS substation, expansion joints are arranged between the busbar barrels to adapt to the thermal expansion and cold contraction of the busbar barrels. The busbar barrel is supported by the busbar support device. In order to adapt to the movement of the busbar barrel, the currently commonly used busbar support device is equipped with a relatively sliding slider. Normal movement can easily lead to cracking of the weld seam of the busbar barrel. Contents of the invention [0003] The purpose of the present invention is to provide a busbar support device, which is used to solve the problem that the slider of the current busbar support device is easily stuck and affects the normal movement of the busbar barrel, thereby easily leading to the cracking of the weld seam of the busbar barrel; in addition, ...
