Abstract
The utility model discloses an iron core ground lead which comprises a plurality of insulators; porcelain sleeves are arranged outside the insulators; the lower end of each insulator is connected with a bottom plate, and the bottom plate is used for installing and fixing the insulator; the lead is characterized in that the upper end of the porcelain sleeve of each insulator is provided with a fixed seat, and the fixed seat is connected with a pressure plate through a bolt; and 'L'-shaped ground copper buses are sequentially clamped between the fixed seats and the pressure plates of the insulators, and the lower end of each 'L'-shaped ground copper bus is grounded. The ground lead has the advantages of simple and practical structure, higher design efficiency and quality, lower processing and manufacturing difficulty and higher assembly efficiency, and eliminates the phenomenon that the ground lead cannot be installed caused by error. The simple structure is characterized by simple processing and convenient installation. The iron core ground lead can be widely applied to the iron core ground lead structure of large-sized and medium-sized power transformers.
Description
Technical field:
The utility model is applicable to Large and Medium-sized Power Transformer iron core grounding lead-in wire, belongs to the transformer technology field.
Background technology:
Transformer core requires necessary ground connection, concerning big-and-middle-sized transformer, uses for the convenience of the user, usually iron core grounding is caused the transformer bottom.Ground lead has power cable, two kinds of structures of copper busbar, and is safe and reliable to operation for guaranteeing transformer, and increasing user priority is selected the copper busbar earthing mode for use, compares, and adopts copper busbar ground lead structure to want complicated.Usually, ground connection copper busbar in the iron core grounding lead-in wire of transformer requires very accurate, because this ground connection copper busbar need accurately cooperate with supporting insulator and base plate thereof, and the copper busbar of ground lead is formed by two to three usually, the copper busbar that wherein has needs the many places bending and fixing hole is set, and has increased design, manufacture difficulty virtually.Because copper busbar installation dimension and base plate location dimension are easy to overproof or mistake, cause copper busbar to install, need do over again and handle even make again.Thereby influence the installation progress of transformer, operating efficiency is reduced, the manufacturing cycle prolongs, and cost increases.Therefore, seek very necessity of a kind of simple and practical ground lead.
Summary of the invention:
The purpose of this utility model just provides a kind of simple iron core grounding lead-in wire, it comprises " L " type ground connection copper busbar, insulator and the base plate of insulator is installed, it has avoided the processing and the repeatedly bending of different angles of ground connection copper busbar fixing hole, improve effectively and make and efficiency of assembling, can be widely used in the iron core and the folder ground lead of power transformer.
The technical solution of the utility model is as follows:
A kind of iron core grounding lead-in wire, include several insulators, insulator has insulator outward, each insulator lower end is connected with base plate, described base plate is used for installing and fixing of insulator, it is characterized in that: described each porcelain insulator set upper side is equipped with holder, is connected with pressing plate by bolt on the described holder; There is " L " type ground connection copper busbar to be clipped in successively between the holder of each insulator and the pressing plate and fixing, the lower end ground connection of " L " type ground connection copper busbar.
Advantage of the present utility model is:
The utility model has overcome the problem that assembling cooperates existence of making, because the utility model has been taked above scheme, make ground lead simple and practical, design efficiency and quality improve, the processing and manufacturing difficulty reduces, efficiency of assembling improves, and has eliminated because the phenomenon that ground lead can't be installed that error causes.This simple structure has simple and easy, the easy for installation characteristics of processing.Can be widely used in Large and Medium-sized Power Transformer iron core grounding pin configuration.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is for being the structural representation of the utility model insulator.
Embodiment:
Referring to Fig. 1-2:
A kind of iron core grounding lead-in wire, include several insulators 2, has insulator 4 outside the insulator 2, each insulator 2 lower ends are connected with base plate 7 by bolt, described base plate 7 is used for the oil tank wall that is fixed on of insulator 2, each insulator 2 insulators 4 upper ends are equipped with holder 3, are connected with pressing plate 5 by bolt 6 on the described holder 3; There is " L " type ground connection copper busbar 1 to be clipped in successively between the holder 3 of each insulator 2 and the pressing plate 5 and fixing, the lower end ground connection of " L " type ground connection copper busbar 1.
" L " type ground connection copper busbar does not need perforate to install, and only needs to fix with the pressing plate of insulator; The base plate that is used to install insulator can make ground lead keep " L " shape according to the size of grounding sleeve and the structure of fuel tank.
