Guarantee that safety is used when electrical body generates electrostatic induction electric shock or false switching.General mounting means is, when hanging earthing conductor: first connecting
Earth clip is tied, is followed by connecing electric folder;Remove ground line when, it is necessary to electric folder is first disconnected by program, after tear earth clip open.(2) it installs: will connect
Eyes copper lug is fixed on grounding rod and connects electricity folder (connect electricity accompany fixed and movable) corresponding positions in ground annealed copper wire split-phase
It sets, ground line is closed into the simple eye copper lug in phase and is fixed on earth clip or ground needle, the ground line of complete set is constituted.(3)
Ground connection annealed copper wire has split-phase type and combined type, and grounding rod has flat and two-man act hook-type wire clamp.And the space of high-speed rail is limited, in order to
The integrated level for improving harness needs to facilitate inspection and installation to mostly boundling confluence is carried out with high-voltage grounding wire.
Summary of the invention
Aiming at the problem that mentioned above come out, the purpose of this utility model is to provide a kind of high-voltage lines to be grounded header box,
Unified installation of converging is carried out to high-voltage grounding wire by ground terminal platform, prevents the safety accident as caused by imperfect earth from sending out
It is raw.
The technical solution of the utility model is achieved in the following ways: a kind of high-voltage line is grounded header box, by cabinet,
Case lid, lower bracket, ground terminal platform assembly composition, cabinet are the metal shell constructions that single side opening is integrally formed using metal plate,
Wall box surrounding is provided with multiple threading holes, and case lid is fixed on above cabinet by hexagon socket head cap screw, and lower bracket passes through welding
Mode be fixed on the bottom of box, ground terminal platform assembly is mounted on box house, it is characterised in that: the lower bracket be bridge
Type sheet metal structural, there are four rectangular lightening hole, left and right sides installation sides to be provided with installation fixation hole for upper plane setting.
The ground terminal platform assembly is made of mounting base, partition, copper sheet, line card end, and partition is fixed on installation bottom
On plate, copper sheet is fixed in partition, and line card end is fixed on copper sheet.
The mounting base is three frame type structures made of insulating materials, when being mounted on box house, at hollow knot
Structure, convenient for heat dissipation.
The partition is that U-shaped structure is made in insulating materials, and two partitions are one group, and two groups of partitions are fixed on mounting base
Middle position forms interval between two groups of partitions.
The copper sheet is I-shaped structure part, and the three of copper sheet are respectively set there are two line card end mounting hole while upper per,
It in total can 12 high-voltage grounding wires of maximum connection.
The utility model can install high-voltage grounding wire using space to greatest extent using partition design, can be effective
Maloperation bring safety accident is avoided, connection is reliable and is easily installed, dismantles, and the scope of application is wider.
