Abstract

The invention provides a silicone rubber creepage extender shield and a mounting technique thereof. The silicone rubber creepage extender shield comprises a chassis, a base plate, a cover and a lug boss, wherein the middle part of the chassis is opening; a first channel is arranged on the surface of the chassis; a first connecting part and a second connecting part are arranged on the two sides of the first channel; the first connecting part and the second connecting part are coincided with each other, so that the chassis is closed; the base plate is internally connected with the opening of the chassis; a first notch is arranged on the base plate; the cover is covered on the chassis; a through hole is formed in the middle of the cover; a second channel is arranged on one side of the cover; a third connecting part and a fourth connecting part are arranged on the two sides of the second channel; the third connecting part and the fourth connecting part are coincided with each other, so that the cover is closed and is jointed with the chassis; the lug boss is covered on the cover along the peripheral direction of the through hole of the cover; a port is arranged in the middle of the lug boss; a second notch is arranged on the lug boss. The creepage extender has excellent material performance; a large-diameter flash creepage extender has a certain self-cleaning function and shows the performance better than that of an anti-fouling insulator; the creepage extender is especially suitable for a high voltage large-scale power substation which is difficult to cut off power or to clean under an electrified state.

Description

technical field [0001] The invention belongs to the field of electric power component manufacturing in electrical protection engineering, and in particular relates to a silicone rubber creepage-increasing skirt shield and an installation process thereof. Background technique [0002] The electric porcelain surface of power equipment is polluted by solid, liquid and gaseous conductive substances. When it encounters moisture such as fog, dew and drizzle, the conductance of the dirty layer will increase, the leakage current will increase, and partial discharge will be generated. Partial discharge on the surface of ceramic parts under voltage develops into arc flashover, which is called pollution flashover. Pollution flashover of equipment will seriously affect the safe operation of the power system. And when the equipment is polluted flashover, the success rate of reclosing is very low, often resulting in large-scale blackout accidents, which are called pollution flashover acc...
