Abstract

A 220KV mutual inductor overhauling workbench belongs to the technical field of design and manufacturing of a mutual inductor overhauling workbench. The bottom of a ladder is provided with a bottom feet fixing plate. An adjusting plate is provided with a fixed pin hole. The top of the ladder is provided with a workbench surface which is semi-circular. A support plate is arranged between a connecting plate and the ladder. The use of the overhauling workbench is as follows: a fixing groove is arranged on a mutual inductor equipment framework and is connected and fixed with the framework by a bolt; and then the workbench surface is abutted on a porcelain pillar, so that an operator can climb onto the workbench surface to conduct overhauling operation by virtue of the ladder. The 220KV mutual inductor overhauling workbench has simple structure, reasonable design, small volume, and convenient movement, not only solves the problem that the operator destroys the coating layer of the porcelain pillar when climbing the ladder, but also prevents loss of life and personal injury and power failure accidents caused by fracture of the porcelain pillar, thus being an extremely ideal current mutual inductor overhauling tool.

Description

220 kilovolts of instrument transformer service work platforms
Technical field
The utility model belongs to the design and the manufacturing technology field of instrument transformer service work platform.
Background technology
The framework of 220 kilovolts of existing domestic current transformers is very high, and in the needs maintenance, the staff must carry out ascend operation.Generally all be to adopt on the waist to fasten safety rope, the other end of will restricting ties up on the porcelain knob to be operated, perhaps by means of tool operations such as lift or ladders.But all scribble RTV coating on the instrument transformer porcelain knob, the direct climbing of staff can damage dope layer.Because have coating, the porcelain knob face is very sliding, and the staff operates and very requires great effort.In addition,, cause the porcelain knob fracture in recent years, cause the thing of electric substation's power failure and casualties that generation is also arranged owing to quality problems and other reasons of porcelain knob.So forbidding safety rope tied up on the porcelain knob, power department regulation works.Therefore say that present service work for current transformer exists many practical problems.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of 220 kilovolts of current transformer inspection platforms, to solve the problem that existing method of operation exists.
Structure of the present utility model is as shown in drawings: a footing fixed head is arranged in the bottom of ladder.Have holddown groove below the footing fixed head, an angle adjustment plate is arranged between footing fixed head and ladder.Have fixed pin holes on the adjustable plate.At the top of ladder one work top is arranged.Work top is semicircle.A plate is arranged at the bottom at work top, and work top connects with ladder mutually by connecting plate.One supporting bracket is arranged between connecting plate and ladder.Use of the present utility model is that holddown groove is installed on the instrument transformer equipment frame, connects holddown groove and framework fixing by bolt.To prevent that ladder from sliding.Again work top is abutted on the porcelain knob.Operating personnel can be by carrying out inspection operation on the ladder to work top.The utility model is simple in structure, and is reasonable in design, and volume is small and exquisite, is convenient to move.Adopt this product that 220 kilovolts of instrument transformers are carried out inspection operation, the personnel that both solved climb the problem of destroying the porcelain knob dope layer, have also prevented to be a kind of very good current transformer service kit because the porcelain knob fracture causes casualties and power outage.
