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 GIL fixed three-pillar insulator welding device. The fixed three-pillar insulator welding device of GIL includes a fixed seat for coaxially sleeved on the center conductor of GIL. The pressing ends of the parts are located on the same circumference, and the center of the circle is located on the axis of the fixing seat. The components are connected to the same power source to achieve synchronous expansion and contraction. The fixed three-pillar insulator welding device of the GIL can realize the synchronous expansion and contraction of the three pressing parts by operating the power source, and the operation is convenient; the pressing parts can simultaneously compress the connecting plates fixed on the three pillars during the synchronous stretching process, and then The coaxiality between the central conductor and the barrel 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...
