Abstract

The utility model relates to a grounding device for maintenance of a box-type transformer. The grounding device comprises a box body, male head connectors and grounding wires. The three male head connectors are arranged on the box body, the connecting ends of the male head connectors are matched with cable female port joints of the box-type transformer, and the grounding wires are guided out of the other ends of the three male head connectors. The problem that when maintenance personnel carry out maintenance on the box-type transformer, critical damage easily occurs due to the fact that misoperations are carried out on a far-end electric three-phase cable or effective switching off is not carried out in the maintenance of the box-type transformer and cable female ports of the box-type transformer have high voltages is solved. The grounding device has the advantages of being simple in structure, low in manufacturing cost, easy and convenient for operation and high in safety factor. The cable female port joints of the box-type transformer end are inserted into the male head connectors and are directly grounded, the potential safety hazard that the cable female port joints have electricity is eliminated, and the potential safety hazard is eliminated completely.

Description

A kind of box type transformer inspection earthing device
Technical field
The utility model relates to earthing device, especially a kind of earthing device for three phase box like transformer maintenance.
Background technology
Box type transformer is when maintenance, need to be the disconnected lock of the charged threephase cable of far-end, female mouthful of joint of cable of box type transformer is now not charged, can manually take off, but can there is certain hidden danger, such as because of the charged threephase cable misoperation of far-end or the lock that effectively breaks, now the female mouth of the cable of box type transformer is with high-tension electricity, when operating personnel carry out box type transformer maintenance, easily produce mortal injury, therefore be necessary female mouthful of joint of the cable of box type transformer end to carry out grounding, and do not occur on the market at present similar earthing device.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly in maintenance, time can guarantees the complete uncharged box type transformer inspection earthing device of high-tension cable.
The technical solution adopted in the utility model is: a kind of box type transformer inspection earthing device, comprise casing, Male head connector, earth connection, described casing is provided with three Male head connectors, female mouthful of joint of the link of described Male head connector and the cable of box type transformer is suitable, and the other end of three Male head connectors is drawn earth connection.
Further, the arrangement mode of described Male head connector is for there being each other the mode side by side of certain intervals.
Further, the arrangement mode of described Male head connector is for there being each other the rounded projections arranged mode of certain intervals.
Further, the other end of described Male head connector is drawn earth connection and is pooled one.
Further, described casing adopts box cabinet.
Further, described casing adopts insulation box.
Further, described casing adopts screw thread to be fixedly connected with or to weld with Male head connector.
When work about electric power personnel carry out box type transformer to overhaul, the ground connection on box type transformer inspection earthing device, female mouthful of joint of the cable of box type transformer extracted from the Male head connector of box type transformer, insert on the Male head connector of box type transformer inspection earthing device, reach ground connection object.
Compared with prior art, the utlity model has simple in structure, low cost of manufacture, simple to operation, coefficient of safety is high, female mouthful of joint of cable of box type transformer end inserts the direct ground connection of Male head connector, eliminated female mouthful of charged potential safety hazard of joint of cable, can make potential safety hazard be reduced to zero.
