Abstract

Disclosed is a method of insulating substation operation equipment characterized by comprising a first step of cutting off a heat shrink tubing and punching a hole at a position 5CM from a gap for installation of a fastener; a second step of removing a fitting on an insulating porcelain bottle of a busbar bridge, wrapping a copper busbar up with a side of an insulating sheath, aligning the position of the fastener, punching a hole in another side of the insulating sheath, and then sealing the insulating sheath with the fastener to achieve insulation of the copper busbar bridge; and a third step of fixing the copper busbar with the insulating porcelain bottle through the fitting. The method of insulating the substation operation equipment can prevent fatalities such as short circuits and the like caused by falling of branches, floating objects and the like onto a conductor due to unusual weather (i.e., severe weather such as high winds, thunderstorms, fog, hail, icing and the like), and prevent tripping accidents such as pollution flashover, condensation flashover, snow pack and the like; meanwhile, effectively prevents short circuits caused when small animals climb onto and cross exposed energized conductors; and effectively improves the insulation level of the substation operation equipment, thereby ensuring safe operation of a power grid.

Description

The apparatus insulated method of a kind of power transformation operation

Technical field:

The exposed conductors such as the present invention is applied to step-down station, the 10KV of transformer station bus, distribution transformer secondary bus bridge, used change secondary bus bridge, electric terminal, be flexible coupling are specifically related to the apparatus insulated method of a kind of power transformation operation.

Background technology:

The step-down station that is established in last century 80, the nineties, its high voltage electric equipment is open type equipment, the electric conductors such as transformer, arc suppression coil, used change, 10KV bus bridge are all exposed, and specifications and models are various, very easily because of toy, bad weather etc. line to line fault, single-phase earthing accident occur.

Summary of the invention:

In order effectively to prevent short circuit accident, ensure the safe operation of electric power system, the present invention proposes the apparatus insulated method of a kind of power transformation operation.

Technical scheme of the present invention is:

First step: heat-shrink tube is cut off, and clasp nail is installed in punching at 5CM place, distance slit;

Second step: remove the gold utensil on the bus bridge porcelain insulator, with insulating sleeve copper busbar is wrapped up, aim at the position of clasp nail, burrow at the insulating sleeve opposite side, then, with sealing insulating sheath, realize the insulation to the copper busbar bridge with clasp nail;

Third step: with gold utensil copper busbar and porcelain insulator are fixed at last.

In the described second step, run into the porcelain insulator place, insulating sleeve is torn open be cut into length for apart from 10cm place, porcelain insulator two ends, always be about 25cm, insulating sleeve is wrapped from the top down, lower-left side, lower right side are cut into arc line shaped, then seal with clasp nail.

In the described third step, in the copper busbar junction, with sealing with clasp nail behind the insulating sleeve system cover.

The present invention can prevent from dropping on the conductor, causing the serious accidents such as short circuit, prevent the trip accidents such as pollution flashover, condensation flashover, accumulated snow because special weather (strong wind, thunderstorm, dense fog, hail, freezing etc. bad weather) causes branch, drift etc. to take; Effectively take precautions against simultaneously toy and climbed up the short circuit accident that causes when exposed energized conductor is crossed over; Effective Raise the insulation level of power transformation operation equipment, guarantee the safe operation of electrical network.

Embodiment

Embodiment:
