Embodiment Construction

[0013] Such as figure 2 As shown, the present invention is an anti-bird damage pressure equalizing ring, including a pressure equalizing ring body 1, and an umbrella group edge 2 is fixed around the pressure equalizing ring body 1, and the umbrella group edge 2 is a silicone rubber composite material. The umbrella group side 2 is also connected to the center of the pressure equalizing ring body through radial ribs 3 to play a supporting role; the umbrella group side 2 is two semicircular structures, which are respectively fixed to the two semicircular structures of the pressure equalizing ring body 1 .

[0014] The traditional anti-bird droppings pressure equalizing ring is an integral closed structure, which is installed on the required equipment through the hole in the center when in use, and then the bolt 4 can be fixed tightly. The present invention adds a circle of silicone rubber composite material umbrella skirt along the traditional anti-bird droppings pressure equal...

Abstract

The invention discloses a bird trouble prevention grading ring. The bird trouble prevention grading ring comprises a grading ring body, wherein an umbrella skirt edge is fixed on the periphery of the grading ring body, and the umbrella skirt edge is made of silicone rubber composite materials. The bird trouble prevention grading ring can increase the overall size, thereby achieving the purposes of increasing the protective area, improving the shielding area of bird droppings, and preventing bird troubles.

Description

technical field [0001] The invention relates to a voltage equalizing ring in power transmission line equipment, in particular to a novel anti-bird damage voltage equalizing ring suitable for composite insulators and spacers of power transmission lines. Background technique [0002] At present, the problem of bird tripping on transmission lines is becoming more and more prominent, and it involves a wide range of hazards. The faults caused by bird damage are more serious than imagined, and the direct loss of power system caused by bird damage reaches tens of millions of yuan every year. In the past, bird damage trips mainly occurred on 220kV and 110kV lines, but in recent years, bird damage accidents on 500kV lines have also occurred from time to time, causing serious damage and difficult prediction. The main manifestation of the tripping problem caused by bird damage is guano flashover. Guano flashover is a sudden event. There is no and impossible to have any symptoms befor...
