CN202111347U - 10kV junction box grounding wire - Google Patents

Abstract

The utility model relates to a ground wire for a 10kV distribution box, which includes three cable elbows, one end of each cable elbow is respectively connected with a metal wire, and the three metal wires are fixed in the connecting wire clip and converged into one Metal wires, the ends of the metal wires are fixed with copper terminals, and the copper terminals are fixed on the grounding equipment through screws. The two ends of the operation section of the power failure line are grounded to achieve the purpose of the grounding wire, prevent the line from reverse power transmission, and ensure the safety of the operation. It can also narrow the scope of safety measures, reduce the number of groups of ground wires, and shorten the power outage time. The structure is simple and easy to use. Remove the 200A protective cap or elbow head in the distribution box, connect the ground terminal, and directly insert the ground wire of the 10kV distribution box to complete the installation of the ground wire.

Description

10kV junction box grounding wire

technical field

The utility model relates to the high-voltage electrical field, in particular to a grounding wire of a 10kV distribution box. the

Background technique

In the prior art, the ground wire cannot be hung on the junction box, which expands the scope of safety measures. the

Utility model content

The technical problem to be solved by this utility model is to provide a 10kV junction box grounding wire with high safety and capable of preventing reverse power transmission of equipment. the

In order to solve the problems existing in the prior art, the technical solution adopted by the utility model is: 

10kV distribution box grounding wire, including three cable elbows, one end of each cable elbow is respectively connected with a metal wire, the metal wire is fixed in the connection clamp and converged into a metal wire, the end of the metal wire is fixed and installed There are copper terminals, which are screwed to the grounding device.

The advantages and effects that the utility model has are:

1. The grounding wire of the 10kV distribution box of the utility model has high safety in use. Through its connection with the four-way busbar of the distribution box, it can ensure that both ends of the power failure line are grounded, so as to achieve the purpose of the grounding wire and prevent the reverse power transmission of the line. Ensure the safety of the work.

2. The grounding wire of the 10kV distribution box of the utility model can reduce the scope of safety measures, reduce the number of groups of grounding wires, and shorten the power failure time. the

3. The grounding wire of the 10kV junction box of the utility model has a simple structure and is easy to use. After removing the 200A protective cap or elbow head in the junction box and connecting the grounding terminal, insert the ground wire of the 10kV junction box directly to complete the installation of the grounding wire. the

Description of drawings

Figure 1 is a schematic diagram of the overall structure of the ground wire of the utility model 10kV junction box. the

In the figure: cable elbow 1; multi-strand annealed copper wire 2; connecting wire clamp 3; copper terminal 4; screw 5; round hole 6. the

Detailed ways

As shown in Fig. 1, the ground wire of the 10kV distribution box of the present invention includes three cable elbows 1, and the cable elbows 1 are used to connect with the four-way busbar of the distribution box. the

One end of each cable elbow 1 is respectively connected with a metal wire, and the metal wire is made of multiple strands of annealed copper wire 2 .
