The earth terminal of traditional portable short-circuit grounding wire is carried out by the way of three-phase is individually twisted and is pressed on earth conductor
There is problems with when actually used in ground connection, this traditional portable short-circuit grounding wire：
Lead because the earth terminal of traditional portable short-circuit grounding wire is installed in ground connection by the way of three-phase is individually twisted and pressed
On body, lead so existing and abutting against ground terminal by mistake in the non-dead short of three-phase ground line (i.e. a certain phase or biphase not short circuit), work
Cause is released, personnel disconnect ground terminal equivalent risk by mistake.After there are the problems referred to above, short-circuit grounding wire can not will pacify to the person of maintainer
Holotype ultimately results in the generation of personnel's electric shock injures and deaths event into protection.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of above-mentioned background technology, there is provided a kind of portable short-circuit grounding wire
And its installation method.
In order to realize object above, a kind of portable short-circuit grounding wire that this utility model is provided, including short-circuit grounding wire
Body, the earth terminal of the short-circuit grounding wire body includes A phase earth terminals, B phases earth terminal and C phase earth terminals again, also including
It is contour respectively in the four grounded stake being located on earth conductor, four ground studs to offer ground connection screw；The A connects
The end of ground terminal, the B phases earth terminal and the C phases earth terminal has been connected respectively A phase connection noses, B phase connection noses
Son and C phase connection noses, on the A phase connections nose, the B phase connections nose and the C phase connections nose spiral shell is offered
Stricture of vagina nostril, the aperture in the screw thread nostril is identical with the aperture of the ground connection screw；The A phase connections nose, the B phase connections
Nose and the C phase connections nose are inserted into respectively between corresponding two ground studs, described to be grounded screw and the spiral shell
The contour arrangement in stricture of vagina nostril, the two sides of the A phase connections nose, the two sides of the B phase connections nose and the C phase connections nose
The two sides of son are in close contact respectively with the corresponding side surface of corresponding two ground studs, described to be grounded screw and the screw thread
Clamping screw is closely interspersed with nostril, the screw head of the clamping screw is provided with the locking nut of cooperation, the locking
Nut press mounting on the lateral surface of a ground stud being in outermost two ground studs, the clamping screw
Head be fitted on the lateral surface of another ground stud being in outermost two ground studs, the locking
