Abstract

Provided is a 500 k V rod clavate composite insulator anti-icing flashover big shield, comprising a lower fixed ring with the top connected to a lower part of an upper fixed ring; one side of the lower fixed ring is provided with a second notch; one side of the upper fixed ring close to the second notch is provided with a first notch. One edge of the second notch is hinged to one side of a fixed plate, and the other side of the fixed plate is hinged to a fixed block; the fixed block is provided with a third slot; an upper surface of the fixed ring on the third slot is in connection with a rotary buckle which is in cooperation with the third slot. According to the utility model, the fixed plate is hinged to the lower fixed ring; the 500 k V rod clavate composite insulator anti-icing flashover big shield can be installed without deformation of the shield and can be fixed to an insulator only by opening the fixed plate, thereby avoiding damaging the big shield in installation; in addition, the big shield requires no special installation technique of operation personnel, reduces installation time and substantially raises installation efficiency.

Description

The large full skirt of 500kV composite rod insulator anti-ice-flashing
Technical field
The utility model relates to the large full skirt of a kind of insulator anti-ice-flashing, specifically the large full skirt of a kind of 500kV composite rod insulator anti-ice-flashing.
Background technology
China is one of the most serious country of powerline ice-covering in the world.In recent decades, in succession there is the large area Harm Accident of nationwide, transmission line and shaft tower large area icing, power transformating and supplying facility is badly damaged, and wherein the flashover fault of insulator also occurs time and again, has a strong impact on the safe operation of transmission line.In order to reduce the generation of regional large area transmission line iceberg fault, in conjunction with sending out ice arcing fault, analyze the reason that causes that composite insulator ice dodges, prophylactico-therapeutic measures has been proposed.The large full skirt of traditional anti-ice-flashing is a side opening, one side opening that need to make full skirt deformation expand full skirt in the time that the large full skirt of anti-ice-flashing is installed is enclosed within on insulator the large full skirt of anti-ice-flashing, this way is easy to make full skirt to damage, cause unnecessary loss, and while installation, need operating personnel's skill, set-up time is longer, has greatly affected installation effectiveness.
Utility model content
The purpose of this utility model is to provide the large full skirt of a kind of 500kV composite rod insulator anti-ice-flashing, can address the above problem.
The utility model for achieving the above object, be achieved through the following technical solutions: the large full skirt of a kind of 500kV composite rod insulator anti-ice-flashing, comprise lower retainer ring, top connects the bottom of upper retainer ring, one side of lower retainer ring is offered the second breach, upper retainer ring is offered the first breach near a side of the second breach, one side of a hinged fixed head in limit of the second breach, the hinged fixed block of opposite side of fixed head, on fixed block, offer the 3rd saturating groove, lower retainer ring upper surface is positioned at the 3rd saturating groove place and connects turn buckle, and turn buckle coordinates with the 3rd saturating groove.
In order further to realize the purpose of this utility model, can also be by the following technical solutions: the inner side of fixed ring arranges the first cushion.Described fixed head arranges the second cushion towards upper retainer ring one side.Described fixed head is positioned at retainer ring one end and coordinates with the second breach, and fixed head is positioned at lower retainer ring one end and coordinates with the second breach.
The utility model has the advantage of: fixed head of the present utility model and lower retainer ring are hinged, in the time that 500kV composite rod insulator anti-ice-flashing large full skirt is installed without making full skirt deformation, only need open fixed head just can make the large full skirt of 500kV composite rod insulator anti-ice-flashing be fixed on insulator, avoided damaging full skirt in the time that the large full skirt of anti-ice-flashing is installed, and, skill without operating personnel is installed, has reduced the set-up time, greatly improved installation effectiveness.The large full skirt of 500kV composite rod insulator anti-ice-flashing is easy for installation, quick, carries out large area and changes the high problem of production cost causing moving insulator without considering.Can effectively prevent timely transmission line and Substation Insulator ice and dodge tripping operation, have important construction value for improving transmission line safe operation.Ensure the safe operation of transmission line and the reliability of transmission facility, reduced maintenance workload, strengthened the safe operation ability of electrical network, for ensureing that electric power netting safe running has very important meaning, power circuit safe operation has been effectively improved.The utility model also has advantages of compactness simple for structure, cheap for manufacturing cost and easy to use.
