Abstract
A low-voltage tapping box cable grounding device belongs to the electric field. Aiming to solve the problem that the low-voltage tapping box in city network has narrow space and complicate power points, and meet requirements of Electrical Safety Rules, the utility model discloses a grounding device formed by four insulating flexible wires with electric clippers at the head ends, wherein one flexible wire is an electric wire and the rest three are three-phase connecting wires; the tail ends of the four insulating flexible wires are electrically connected with a busbar; and the electric clippers of the three-phase connecting wires are arc-shaped, and are in the colors of yellow, green, and red, respectively. By adopting the grounding device, wiring exposure is avoided, no potential safety hazard is left, the use is convenient, and the grounding time is shortened, that is the power cut time is shortened.
Description
Technical field
The utility model relates to a kind of low pressure distribution box cable grounding device, belongs to electric field.
Background technology
Because city net mesolow cable distribution box is more and more; when in the low pressure distribution box, working; because the space is narrow and small, is again cable line, sub-district power supply point more complicated; the safety regulations regulation will be beaten earth connection in the both sides, job site; conventional earth connection can't be installed, and the safety supervise and examine disapproves again with lead twines, therefore; in order to ensure staff's life security, people urgently wish to have manufactured experimently a kind of small-sized earthing device and protect.
Summary of the invention
At characteristics such as low-voltage cable distribution box version, mounting meanss, the utility model provides a kind of low pressure distribution box cable grounding device.
To achieve these goals, the technical solution of the utility model is that this device is made up of the insulated flexible cord of four charged folders of head end, wherein, one for connect wires, its excess-three root is the three-phase connecting line, described four tail ends that thoroughly do away with the edge flexible cord are electrically connected, and the electricity folder of three-phase connecting line is curved.
The beneficial effects of the utility model are: 1, esy to use, safe and reliable, rational in infrastructure, with low cost, 2, avoided the wiring exposure, do not stay potential safety hazard, 3, because the time shortening of installing earth connection, interruption duration just reduces, amount of power supply increases thereupon, has improved the economic benefit of power supply department preferably.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is an electricity folder binding nut schematic diagram of the present utility model.
In the accompanying drawing, 1. earth connection, 2-A, 2-B, 2-C. three-phase connecting line, 3. busbar, 4. nut 5. electricity folders.
Embodiment
With reference to accompanying drawing 1; the utility model is connected in busbar 3 by four electricity folders of insulation sealing sheath protection mutually by the transparent flexible conductor of the multiply that is attached thereto; distinguish three-phase connecting line 2-A, 2-B, 2-C for convenience; in the present embodiment, it is yellow, green, red that three colors that are connected 2-A, 2-B, 2-C are respectively.
Before the maintenance of low-voltage cable distribution box, for avoiding overhauling the safety that the unexpected incoming call in position jeopardizes the person and equipment, elder generation is connected the electricity folder of the earth connection of this device on the ground network of working site, electricity folder 5 with the three-phase connecting line is connected on respectively on the circuit breaker lower end three-phase wiring nut 4 of low-voltage cable distribution box then, because electricity folder 5 is curved screw 4 is encased, increase contact area.When removing earthing device, its order is just in time opposite.
In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation form, all drop on the protection range of the utility model requirement.
Claims (3)
1. low pressure distribution box cable grounding device, it is characterized in that this device is made up of the insulated flexible cord of four charged folders of head end, wherein, one for connect wires, its excess-three root is the three-phase connecting line, described four tail ends that thoroughly do away with the edge flexible cord are electrically connected, and the electricity folder of three-phase connecting line is curved.
