Abstract
The invention discloses a grounding wire intermediate connector. The grounding wire intermediate connector comprises a metal panel, a concave upper insulation panel, a lower insulation panel of the same structure as the upper insulation panel, and a side insulation panel. The side insulation panel is an insulation panel whose shape is the same as the shape of the side of the metal panel. The side insulation panel comprises more than one grounding wire access hole arranged with equal spacing. The side wall of the metal panel is enclosed by the side insulation panel. Through opposite grooves of upper and lower insulation panels, the metal panel and the side insulation panel are sandwiched in the groove port, and are fixed by a fastener. According to the grounding wire intermediate connector provided by the invention, a grounding wire is divided into multiple ways which can be simultaneously used; when the grounding wire intermediate connector directly touches a grounding body, multi-point grounding of a grounding wire is prevented.
Description
Technical field
The present invention relates to a kind of power industry servicing unit, particularly relate to a kind of ground wire intermediate head.
Background technology
When carrying out transformer and being long when induced voltage and partial discharge test, need to use working earthing and protective ground two ground wires, because operating substation ground network is not in absolute zero current potential, in standing, the earth current of various operational outfit can produce larger interference to earth mat, especially in converting plant, for reducing the impact of earth mat on measurement of partial discharge further, require that two ground wires all have and only have a reliable earth point, direct ground connection or impedance earth cannot be there is in the middle of ground wire, there is layer of transparent insulated hull on the surface of ground wire, generally need to use multistage ground wire when carrying out this test, intermediate head is adopted to connect between section and section, so uniquely may occur that the place of direct ground connection or impedance earth has been exactly intermediate head part, because its metallic member of intermediate head used at present is naked state, just easily impedance earth is formed when intermediate head is placed on concrete floor or meadow, at this moment earth mat just becomes polynary interference to the interference of measurement of partial discharge.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, the ground wire intermediate head provided, this intermediate head can well avoid intermediate head to occur this situation of impedance earth.
For reaching the object of foregoing invention, the present invention is achieved through the following technical solutions:
A kind of ground wire intermediate head of the present invention, include a metal decking, the upper insulating panel of spill, with the mutually isostructural lower insulating panel of upper insulating panel and side insulation panel, described side insulation panel is the insulating panel with metal decking side same shape, described side insulation panel includes more than one the ground wire access aperture arranged at equal intervals, described side insulation panel encloses the sidewall of described metal decking, described upper insulating panel and lower insulating panel are with groove relative mode, by metal decking and the clamping of side insulation panel in groove port, and fix with securing member.
Described upper insulating panel and lower insulating panel all adopt equally spaced three threaded holes and screw and metal decking to fix.
Described metal decking sidewall is provided with the shrinkage pool identical with the corresponding bore in ground wire access aperture position as ground wire patchhole.
Described side insulation panel includes 6 ground wire access oral pores arranged at equal intervals.
Described metal decking is right cylinder or cube.
Ground wire intermediate head of the present invention, many grounding wire connectors are entered by metal decking and metal decking sidewall, realize a ground wire to be divided into multichannel and to use simultaneously, when grounding body is directly touched in this ground wire intermediate head, also can not cause the situation of ground wire multipoint earthing.
