Abstract

The utility model belongs to the technology field of power-supply maintenance apparatuses and discloses a 10 kV multipurpose ground wire. The main technical characteristics of the ground wire are that the ground wire comprises a ground hook and an insulation rod flexibly connected with each other, wherein the ground hook and the insulation rod are connected in a screw-threaded manner or a spliced manner; and positioning holes respectively matched with the ground hook and the insulation rod are opened on the ground hook and the insulation rod. According to the 10 kV multipurpose ground wire provided by the utility model, a movable joint is arranged between the ground hook and the insulation rod flexibly connected with each other and the ground wire is usually used as conventional ground wires. When the ground wire is assembled on an overhead bus, the ground hook is disassembled from the insulation rod and an insulation pull rod is directly utilized to raise the ground hook to a ground position. Manufacturing is simple and the ground wire is convenient for high-position and low-position hanging. One ground wire has two functions. Substations are without adding special-purpose ground wires, so that cost is saved.

Description

10kV multipurpose earth connection
Technical field
The utility model belongs to power supply maintenance utensil technical field, relates in particular to a kind of 10kV multipurpose earth connection.
Background technology
At the outdoor 35kV 10kV of transformer station bus all on the shaft tower top, according to ground 4-5 rice.The 10kV bus will utilize insulating ladder to install earth connection at the 10kV bus when turning maintenance, and the easy like this operating personnel's of making mistake is touched charging equipment and caused human casualty accident.The operating personnel that have adopt insulated tension pole directly to choose the method that arrives earth point to earth connection.The insulating bar of this method earth connection in implementation process swings and causes easily mistake to bump charging equipment, and add own wt and make operating personnel not install steadily, accurately earth connection, also be to cause unsafe factor to operating personnel.
The utility model content
The technical problems to be solved in the utility model just provides a kind of 10kV multipurpose earth connection simple to operation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise grounding hook and insulating bar, described grounding hook and insulating bar are flexibly connected.
Its additional technical feature is: described grounding hook and insulating bar are threaded; Described grounding hook and insulating bar are pegged graft; Have the location hole that is complementary on described grounding hook and the insulating bar.
The 10kV multipurpose earth connection that the utility model provides, the dead joint that original grounding hook and insulating bar are connected as a single entity change the articulation that grounding hook and insulating bar are flexibly connected into.When the circuit of normal 10kV switch or switch turns maintenance installing earth connection, grounding hook and insulating bar are linked together, just use the same with common earth connection.When installing earth connection on the bus aloft, grounding hook is pulled down from insulating bar, then directly utilized insulated tension pole that grounding hook is chosen to earth point.So just do not had the swing of insulating bar, alleviated weight yet, made things convenient for operating personnel to install earth connection exceeding bus, improved operating personnel's fail safe.The 10kV multipurpose earth connection that the utility model provides is made simply, makes things convenient for eminence and lower to hang, and an earth connection is dual-purpose, and transformer station need not increase Special grounding wire, has saved expense.As required, grounding hook and insulating bar are threaded or grounding hook and insulating bar grafting, have the location hole that is complementary, better effects if on grounding hook and the insulating bar.
Description of drawings
Fig. 1 is the structural representation of the utility model 10kV multipurpose earth connection.
Embodiment
Be described further below in conjunction with the structure of accompanying drawing to the utility model 10kV multipurpose earth connection.
As shown in Figure 1, the utility model 10kV multipurpose earth connection comprises grounding hook 1 and insulating bar 2, and grounding hook 1 and insulating bar 2 are flexibly connected, and have the location hole 3,4 that is complementary on grounding hook 1 and the insulating bar 2.Grounding hook 1 and insulating bar 2 can adopt and be threaded, peg graft or other connected modes.
The 10kV multipurpose earth connection that the utility model provides, the dead joint that original grounding hook 1 and insulating bar 2 are connected as a single entity change the articulation that grounding hook 1 and insulating bar 2 are flexibly connected into.When the circuit of normal 10kV switch or switch turns maintenance installing earth connection, grounding hook 1 and insulating bar 2 are linked together, just use the same with common earth connection.When installing earth connection on the bus aloft, grounding hook 1 is pulled down from insulating bar 2, then directly utilized insulated tension pole that grounding hook 1 is chosen to earth point.So just do not had the swing of insulating bar 2, alleviated weight yet, made things convenient for operating personnel to install earth connection exceeding bus, improved operating personnel's fail safe.The 10kV multipurpose earth connection that the utility model provides is made simply, makes things convenient for eminence and lower to hang, and an earth connection is dual-purpose, and transformer station need not increase Special grounding wire, has saved expense.As required, grounding hook 1 and insulating bar 2 are threaded or grounding hook 1 and insulating bar 2 grafting, have the location hole 3,4 that is complementary, better effects if on grounding hook 1 and the insulating bar 2.
Protection range of the present utility model not only is confined to above-described embodiment, as long as structure is identical with the utility model 10kV multipurpose ground line configuration, just drops on the scope of the utility model protection.
