Description

A portable combined ground wire device

technical field

The utility model belongs to the field of electric power safety, and relates to a safety maintenance auxiliary tool, in particular to a portable combined ground wire device.

Background technique

In electric power engineering, between the 10kV bus tie switch and the isolating handcart or between the mains and the isolating handcart in each station, in accordance with the safety regulations, the switch and the isolating handcart should be installed with grounding wires during switch maintenance. However, since the lower port of the switch and the lower port of the isolated handcart are connected by busbars, the current busbars are mostly in the form of double rows, and there is no grounding point on the busbars.

The size of the general ground wire is fixed, and it is necessary to select the corresponding size ground wire according to the height of each row of busbars. It is difficult to seal and hang the existing common ground wires for multi-row busbars, and it is necessary for the electric maintenance staff to carry a large number of different sizes during each maintenance. The ground wire is inconvenient to carry and the workload is heavy, wasting time, prone to mistakes, affecting work efficiency and accuracy of safety maintenance work, and may also cause danger.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a combined grounding wire device that is easy to carry, easy to operate, fast and efficient.

The utility model solves the problems of the technologies described above by adopting the following technical solutions:

A portable combined ground wire device includes a metal frame and a ground wire part, the metal frame is composed of two parallel upper top boards and lower bottom boards, and the upper top board and the lower bottom board are connected by a vertical board; the ground wire The line part is composed of a metal sheet, an adjusting bolt and a movable jaw; the adjusting bolt is vertically mounted on the upper top plate through a coaxially arranged nut, and the upper end of the adjusting bolt is coaxially fixed to the metal sheet by a rivet The lower end of the adjusting bolt is coaxially threaded with the movable jaw, and the movable jaw is between the upper top plate and the lower bottom plate.

Moreover, a sliding groove for radially sliding the ground wire component on the upper top plate is provided radially on the top plate of the frame.

Also, multiple sets of ground wire parts may be provided on the metal frame.

Advantage and beneficial effect of the present utility model are:

1. The metal frame of the utility model has a simple structure and is strong and stable. When in use, the upper top plate and the lower bottom plate are firmly engaged between the bus bars, which facilitates the insertion of the ground wire, and maintains the stability of the ground wire during the process, improving maintenance safety sex.

2. The grounding wire part of the utility model adjusts the position of the grounding wire head and the busbar interface by screwing the movable jaw that is threadedly connected with the lower end of the bolt. A general standard grounding wire can be installed according to the position of the upper interface of the busbar, and can be clamped freely. Clamp two-row and three-row busbars to solve the problem that multi-row busbars are difficult to seal and hang. It is convenient and quick, and the operation is simple and controllable.

3. There are sliding grooves on the top plate of the metal frame of the utility model in the radial direction, and the distance between the ground wire parts can be adjusted according to the different radial distances of the busbars, so as to complete the connection of the ground wires according to the needs, which is suitable for different sizes of busbars .

4. The utility model has reasonable design and simple operation. It can realize the sealing and hanging of multiple busbars with ordinary standard ground wires. It not only solves the problem that there is no grounding point on the busbar and it is difficult to seal and hang. , no need to carry a large number of ground wires of different sizes, reduce costs, be convenient and fast, save time, improve work efficiency, ensure maintenance safety, and are suitable for vigorous promotion and use in the power industry.

detailed description

The utility model is described in further detail below through specific examples, the following examples are only descriptive, not limiting, and cannot limit the protection scope of the utility model with this.

A portable combined ground wire device includes a metal frame 1 and ground wire components. As shown in Fig. 1, Fig. 2 and Fig. 3, the metal frame is composed of two parallel upper top boards and lower bottom boards, and the upper top board and the lower bottom board are connected by a vertical plate; the grounding wire part is made of metal sheet 2, adjusting bolt 5 and movable jaw 6; the adjusting bolt is vertically mounted on the upper surface of the upper top plate through the coaxially arranged nut 4, and the upper end of the adjusting bolt is fixed coaxially on the upper surface through the rivet 3. Metal sheet, the lower end of the adjusting bolt is coaxially threaded with the movable jaw, and the bottom end of the movable jaw is between the upper top plate and the lower bottom plate. As shown in FIG. 4 , a slide groove 7 is radially opened on the upper top plate of the frame, and the ground wire component can slide radially on the upper top plate. The ground wire components can be provided in multiple groups according to actual needs. In this embodiment, as shown in FIG. 1 , three groups of ground wire components are provided on the metal frame.

The working principle of the utility model: when in use, place the lower bottom plate of the metal frame of the portable combined grounding wire device on the vertical frame at the lower end of the busbar, and at this time the upper top plate of the metal frame of the grounding wire device is just stuck on the upper edge of the beam of the busbar . After the grounding wire device is installed, insert the ground wire from the two parallel plates of the metal frame, and adjust the movable jaw with the insulating operating rod according to the size of the ground wire interface to complete the sealing and hanging of the busbar. For multiple sets of busbars, set it as required Corresponding number of ground wire components.
