The utility model is to provide a kind of novel subway disconnecting switch ground connection whole link device.Belong to power equipment grounding technology field.It includes M16x90 bolt assembly, copper sheet, self-locking nut, split pin, copper rod that the subway disconnecting switch, which is grounded whole link device,；Copper rod self-locking nut and split pin are fixed on two copper sheets staggered relatively, and the M16x90 bolt assembly is fixed on two copper sheets on the connecting terminal of upper net side of disconnecting switch, composition ground connection whole link device.The beneficial effects of the utility model are: solving subway disconnecting switch in daily maintenance, upkeep operation, there is no the problem of position hanging earthing conductor in subway disconnecting switch；Simple, easy to use, ground connection the is reliable feature of structure is mainly used for ground connection of the subway disconnecting switch in maintenance, maintenance.
Description
Technical field
The utility model belongs to power equipment grounding technology field, is tieing up more particularly to one kind for subway disconnecting switch
The device of hanging earthing conductor when shield or maintenance.
Background technique
Daily after metro operation, which terminates train, goes back to field, the service personnel of each profession will execute the maintenance plan of equipment
Or troubleshooting is carried out, to guarantee the normal operation of each system equipment of subway.Contact net equipment power failure hanging ground-wire operation is inspection
The secured premise for repairing construction operation is the most important thing.
The installation of subway disconnecting switch is often all mounted on the tunnel inner wall of underground or on the pillar on ground, subway
The installation site minimum allowable distance of disconnecting switch operates ground 3m, highest installation site distance operation ground 6.5m.Work as service personnel
Have a power failure in contact net equipment, needs to tend not to fast and accurately when positioned at height aerial subway disconnecting switch hanging earthing conductor
The position of hanging earthing conductor is found, ground connection operates the time that is very inconvenient and being delayed upkeep operation.
Summary of the invention
The purpose of this utility model be in view of the above-mentioned deficiencies place and a kind of subway disconnecting switch is provided and is safeguarding or is examining
The device of hanging earthing conductor when repairing.
The technical solution of the utility model is: a kind of subway disconnecting switch ground connection whole link device, including a pair of of L-type copper sheet,
The both ends of the pair of L-type copper sheet of copper rod are respectively equipped with screw hole, and short side corresponding end screw hole is symmetrically fixed on through bolt assembly
On the connecting terminal of the upper net side of disconnecting switch, copper rod is stated in insertion in long side corresponding end screw hole, and the copper rod both ends have
It screw thread and is fixed in the interior outside at L-type copper sheet both ends through self-locking nut and split pin.
The copper sheet, copper rod are red copper material.
The diameter of the copper rod is φ 12mm.
The model M16x90 of the bolt assembly.
The utility model effect is that whole link device, effective solution contact net power failure are grounded using the subway disconnecting switch
When, service personnel needs in hanging earthing conductor in subway disconnecting switch, has accurate mounting on subway disconnecting switch connecting terminal
The position of ground wire, service personnel can accurately, easily hang up properly ground line, save the time for upkeep operation, improve upkeep operation
Efficiency.The utility model has the characteristics that simple in structure, time saving and energy saving, ground connection are reliable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model is grounded whole link device；
Fig. 2 is subway disconnecting switch structural schematic diagram of the utility model with ground connection whole link device.
In figure:
The 1- disconnecting switch online sub- 2-M16x90 bolt assembly of side terminal
3-L type copper sheet 4- self-locking nut
5- split pin 6- copper rod
Specific embodiment
The subway disconnecting switch ground connection whole link device structure of the utility model is illustrated with reference to the accompanying drawing.
As shown in Figure 1, a kind of subway disconnecting switch ground connection whole link device be by M16x90 bolt assembly 2, L-type copper sheet 3,
Self-locking nut 4, split pin 5, copper rod 6 form.Wherein four self-locking nuts 4 of copper rod 6 are fixed on two L-type copper staggered relatively
On plate 3, is fixed with two split pins 5 at 6 both ends of copper rod, falling off for copper rod 6 can be effectively prevent.
As shown in Fig. 2, two M16x90 bolt assemblies 2 of ground connection link component shown in FIG. 1 are fixed on disconnecting switch
Upper net side connecting terminal 1 on, be connected to connecing for the upper net side of disconnecting switch by two corresponding L-type copper sheets 3 and copper rod 6
Subway disconnecting switch is formed in line terminals 1 is grounded whole link device.The electricity folder that connects at the top of grounding rod is connected directly between copper when use
It is simple and convenient on stick 6, greatly improve site operation efficiency.
