Embodiment 1

[0024] (1) Take a metal tubular conductor, with a liquid injection port and an exhaust port at both ends of the conductor, and wrap a layer of tetrafluoroethylene film on the surface of the conductor;

[0025] (2) Put a heat-shrinkable sleeve on the outer wall of the conductor wrapped with tetrafluoroethylene film, and in vacuum state, pour insulation into the cavity between the heat-shrinkable sleeve and the conductor from the liquid injection port on the conductor paint until the resin is full;

[0026] The preparation method of the insulating coating is as follows: 20 parts by weight of epoxy resin, 10 parts of acrylic resin, 2 parts of glyceryl triacetate, 2 parts of epoxy-terminated nitrile rubber, and 1 part of dimethylformamide Put it into the reaction kettle and mix, the mixing time is 3h, the mixing temperature is 60°C, and the mixing speed is 200r / min. After mixing, add 0.8 parts of nano-silica, use ultrasonic dispersion, adjust the viscosity with organic solvent, an...

Abstract

The invention relates to the technical field of transmission equipment, in particular to an insulation tube bus generation method. The method comprises the steps of insulating material pouring, solidifying and shielded copper wire winding. The invention provides the bus production method capable of cutting off static electricity and shielding electromagnetism, thereby solving the problems of extrapower loss and economic loss.

Description

technical field [0001] The invention belongs to the technical field of power transmission equipment, and in particular relates to a production method of an insulating pipe busbar. technical background [0002] Tubular busbar is a high-voltage current transmission device with high efficiency. Compared with traditional rectangular busbar, tubular busbar has good skin effect, large carrying capacity per unit section, good heat dissipation conditions, large allowable stress, large span, and mechanical High strength, strong electrical insulation performance, high stability of the main insulating material, reasonable insulation process and other characteristics can effectively ensure the reliability of power supply of the transmission and transformation grid. With the rapid and steady growth of the national economy, social power consumption is rising linearly, which makes the main transformer capacity of the substation continue to increase, and the rated current of the low-voltage...
