Embodiment Construction

[0026] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] The specific embodiment of the fixed three-pillar insulator welding device of GIL provided by the present invention:

[0028] Such as Figure 4 with Figure 5 As shown, the fixed three-pillar insulator welding device of GIL includes a fixed seat 14 for coaxially sleeved on the central conductor 1. The fixed seat 14 is an annular seat, and a polytetrafluoroethylene ring 11 is installed on the inner wall of the central hole of the annular seat. , the polytetrafluoroethylene ring 11 has a low coefficient of friction, and when the fixing seat 14 is sheathed on the central conductor 1, it forms a cushion layer for preventing the central conductor 1 from being bumped and scratched.

[0029] The fixed three-pillar insulator welding device of GIL also includes three identical hydraulic cylinders 8 uniformly arranged along the outer circumference of the ...

Abstract

The invention relates to a device for welding a fixed three-post insulator of a GIL. The device comprises a fixing seat coaxially sleeving a central conductor of the GIL, wherein the fixing seat is provided with three jacking parts; when in use, the three jacking parts are capable of stretching and contracting along the radial direction of the central conductor; jacking ends of the three jacking parts are positioned on the same circumference; the circle center of the circumference is positioned on the axis of the fixing seat; the jacking parts are uniformly arranged along the circumference ofthe fixing seat to correspond to supporting posts of the fixed three-post insulator; and the three jacking parts are connected with the same power source to achieve synchronous stretching and contacting. According to the device, synchronous stretching and contracting of the three jacking parts can be achieved by operating the power source conveniently; and a connecting plate fixed on the three supporting posts can be synchronously pressed by the jacking parts in the synchronous stretching process, so that the coaxiality of the center conductor and a cylinder body is guaranteed.

Description

technical field [0001] The invention relates to a GIL fixed three-pillar insulator welding device. Background technique [0002] Gas-insulated metal-enclosed transmission lines (GIL) are used to transmit large-capacity UHV currents. They have the advantages of small footprint, little influence from the natural environment, effective electromagnetic shielding, safe and reliable operation, and long inspection and maintenance cycles. The distance transmission system provides an ideal choice and has been widely used in domestic and foreign power systems. [0003] The GIL pipeline line is composed of many busbar units. A fixed three-post insulator is usually arranged in the busbar unit, and the fixed three-post insulator mainly plays the role of insulation and mechanical support. Such as figure 1 with figure 2 As shown, the fixed three-post insulator 2 is fixed to the central conductor 1 in the bus barrel 6 by crimping, and the particulate trap 5 is loaded from one end of the...
