Description

ground wire device

technical field

The utility model relates to a grounding wire device, which belongs to the field of grounding wires for high-voltage equipment in electric power systems.

Background technique

After the integrated reform of power system operation and maintenance and the implementation of unattended substations, the traditional on-duty methods and operating procedures have also changed. Power outages, power inspections, grounding, hanging signs and installing barriers are technical measures to ensure safety. Among them Grounding is an important measure to ensure the personal safety of maintenance personnel. After the unattended mode, the grounding wires are centralized to the operation team station for unified management. Since the electrical equipment of each substation and the locking device to prevent electrical misuse are different, the grounding ends of the grounding wires are also different. The on-site equipment does not correspond, thereby delaying the operation time, and there are many types of grounding wires, causing inconvenience in management and use.

Utility model content

Based on the deficiencies of the prior art above, the purpose of this utility model is to provide a grounding wire device, which greatly saves the types and quantities of grounding wires, and meets the requirements of safety regulations that the grounding wires should be firmly crimped, and is convenient for management and use.

The ground wire device described in the utility model includes a small ground wire and a small ground wire grounding end matched with the small ground wire. The small ground wire grounding end is composed of a microcomputer locking head, a connecting wire and a connecting head. They are arranged at both ends of the connecting wire respectively, the connecting head is composed of a locking part and a connecting part, the locking part and the connecting wire are detachably connected, the connecting part is provided with a through hole, and the small ground wire is connected with another connecting head.

The two connectors are respectively fixed on the ends of the small ground wire and the ground end of the small ground wire through the locking part, and the connecting parts of the two connectors are connected by bolts, so that the small ground wire and the ground end of the small ground wire are connected, and the small ground wire The microcomputer locking head of the connection terminal can be in many different forms, and different types of small ground wire ground terminals are connected to the ground with the small ground wire through the connection head, which greatly reduces the types and quantities of the ground wires.

The microcomputer locking head includes oblong, polygonal and special-shaped structures. The microcomputer locking head uses a common structure on the market, and can be hung with a microcomputer lock to realize locking.

The locking part includes three routing channels, and locking holes are provided between adjacent routing channels. The three routing channels can pass through three wires and be locked through the locking holes. The crimping surface is large and the crimping surface is large. connection is better.

When in use, install the connectors on the small ground wire and the end of the small ground wire terminal respectively, the three-phase electric wires pass through the wiring channel, and press the locking part through the bolt and the locking hole. The connection parts of the two connectors are connected by bolts, so that the small ground wire is connected with the small ground wire terminal, and the other end of the small ground wire is connected with the equipment, and the other end of the small ground wire terminal is hung with a microcomputer lock to realize the grounding operation.

Compared with the prior art, the utility model has the beneficial effects of:

This grounding wire device greatly saves the type and quantity of grounding wires, and meets the requirements of safety regulations that the grounding wire should be firmly crimped, which is convenient for management and use; the microcomputer locking head can be set in various forms, which is easy to use; the connector is equipped with three routings The channel is locked through the locking hole, the crimping surface is large, and the crimping is better.
