Abstract

The utility model discloses a special tool for replacing insulators in electriferous state for a 110kV single tower double circuit. The tool comprises an epoxy tube, an insulation fastening hanger, a lead screw, an angle iron hanger with the end part provided with an operating ring, an ejector rod, and a handle with the end part provided with an operating ring, wherein the insulation fastening hanger is fixed at one end of the epoxy tube; the lead screw is inserted into another end of the epoxy tube and is in threaded connection with the epoxy tube; another end of the lead screw is fixedly connected with the angle iron hanger through a connecting piece; the upper end of the ejector rod is sheathed and fixed on the lead screw, and the lower end of the ejector rod is fixedly connected with the handle. The tool has the characteristics of being high in intensity, good in insulating property, light in weight, and convenient in carrying and operation.

Description

110kV common-tower double-return circuit charged for replacement insulator specific purpose tool
Technical field
The utility model relates to a kind of specific purpose tool of changing insulator.
Background technology
In order to reduce the circuit floor space and to reduce investment outlay, the 110kV circuit uses double loop vertical arrangement tower in a large number at present, but because of its reasons in structure, two-layer cross-arm spacing only is 3.5 meters, and live wire is positioned between two-layer cross-arm, when therefore carrying out live line working, the live line working electrician can not satisfy the safe distance requirement, and personnel are by means of insulated ladder, combinational gap was not enough when instruments such as insulated flexible ladder entered current potential, to lightning stroke flashover in the circuit, null value, wire clamp overheated and make an inspection tour in the equipment deficiency found and hidden danger can not timely charged solution, a large amount of work has only by interruption maintenance and just can finish.When equipotential changed that the 110kV circuit is two to return the tangent suspension tower insulators, there was potential safety hazard in same live line working, and the replacing that can only have a power failure is unfavorable for the reliability of powering causing unnecessary economic loss.
Summary of the invention
For solving the existing charged problem that can not change insulator, the utility model provides a kind of 110kV common-tower double-return circuit charged for replacement insulator specific purpose tool, and its technical scheme of taking is:
Angle bar hook, push rod and the end that this instrument comprises epoxy tube, the fastening hook that insulate, leading screw, end have the operation ring has the handle of operation ring, the fastening hook that insulate is fixed on an end of epoxy tube, leading screw inserts the other end of epoxy tube and is threaded with epoxy tube, the other end of leading screw is by the fixedly connected angle bar hook of connector, the upper end socket of push rod is fixed on the leading screw, the fixedly connected handle in the lower end of push rod.
This instrument has intensity height, good insulation preformance, in light weight, easy to carry, convenience operation, improved operating personnel's processing safety, satisfy the safety requirements of personnel, equipment, broken through the restriction of 110kV common-tower double-return line security distance, adopt the live line working mode, shorten the operating time, reduce the line outage chance, guarantee safe, the reliable power supply of circuit, significant to power grid security economical operation, raising power supply reliability and economic results in society.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Be described further below in conjunction with 1 pair of the utility model of accompanying drawing:
As shown in the figure, the end of angle bar hook 4 and handle 6 all has the operation ring, the fastening hook 2 that insulate is fixed on an end of epoxy tube 1, leading screw 3 inserts the other end of epoxy tube 1 and is threaded with epoxy tube 1, the other end of leading screw 3 is by connector 7 fixedly connected angle bar hooks 4, the upper end socket of push rod 5 is fixed on the leading screw 3, the fixedly connected handle 6 in the lower end of push rod 5.
Each combination of instrument is in aggregates before using on ground, the ground staff restricts instrument to transmitting the installation site with insulation, earth potential electrician A inserts in the operation ring of angle bar hook 4 with insulating bar termination operation hook, cooperates with the ground electrician instrument angle bar hook 4 is fixed on the insulator hanging point place angle bar.Earth potential electrician B moves to live wire front-end operations ring with the action bars fastening hook 2 that will insulate, A cooperates with B after the lead lifting, earth potential electrician A inserts the operation ring of handle 6 with the operation hook of action bars, by push rod 5 rotational lead screws 3, and then the degree of depth of the insertion of adjustment leading screw 3 in epoxy tube 1, increase the length of entire tool gradually, lead is strutted, carry out the replacing of insulator at last.A cooperated with B lead is returned to running status after replacing was finished, and removal tool falls to ground, tower under the personnel, and work is finished.
