Description

A current shunt for power pipe female joint

technical field

The utility model relates to the field of power pipe females, in particular to a current shunt for electric power pipe female joints.

Background technique

The pipe mother is mainly used in the conductor connection between the power grid transmission wire and the substation transformer in my country's electric power construction projects, the jumper in the transmission line, the connecting conductor in the power equipment, and the overcurrent conductor in the high-current DC ice-melting device. One of the key equipment (materials) in the power transmission and transformation system plays a vital role in the safe and reliable operation of the power transmission and transformation system and power equipment.

In actual operation, there is a heating defect in the outer joint of the tube mother. Due to the particularity of the pipe nut itself, the conventional treatment method for such defects is to retighten the outer joint bolts of the pipe nut with electricity or to deal with power failure. The specific operation steps are that the operator enters the electric field according to the live working standard, and re-tightens the outer joint bolts of the pipe nut. Adopting the scheme of re-tightening the external joint of the tube female can only solve the heating defect of the external joint of the tube female caused by the loosening of the external connector of the tube female, if it is not for the heating caused by this reason, it cannot be solved. Therefore, this method has limitations and cannot eliminate the heating defect of the external joint from the root cause. If power failure is used to deal with it, the reliability of power supply will be affected, and a large amount of power load will be lost.

Utility model content

In order to solve the above-mentioned defects and deficiencies in the prior art, the utility model provides a current shunt for a power pipe female joint, which can work live, and has a simple structure and is easy to operate.

In order to solve the above-mentioned technical problems, the utility model provides a current shunt for a power pipe female joint, which is characterized in that it includes a pair of wire clamps and several wires connecting the two wire clamps, and the wire clamps are composed of two wire clamps. It is composed of parts, and when the two parts are spliced together, a cavity is formed inside.

As a preferred technical solution:

The wire clip is integrally formed with the wire.

The two parts of the clamp are fixed by bolts.

The bolts are embedded.

The outer contour of the wire clip is a smooth transition type.

The wire clamp is made of aluminum alloy, and the wire is made of aluminum.

Beneficial technical effect achieved by the utility model:

The heating part of the pipe female joint often has a large resistance value, and the reliability of power supply cannot be guaranteed. However, the device is connected in parallel to the heating part of the pipe female joint. , thereby reducing the current value flowing through the body of the pipe female joint, the calorific value is reduced, and the heating defect of the pipe female joint is resolved. When the utility model is used to deal with the heating defect of the pipe female joint, live work can be carried out, so that the reliability of power supply is guaranteed. The utility model has the advantages of simple structure and convenient operation, and only needs to connect the utility model in parallel at both ends of the pipe female joints to be processed.

Detailed ways

In order for examiners to better understand the technical features, technical content and technical effects of the utility model, the accompanying drawings of the utility model are now described in more detail in conjunction with the embodiments. However, the drawings shown are only for better explaining the technical solution of the utility model, not the real scale and optimal configuration of the utility model. Therefore, the examiner is requested not to limit the scope and configuration of the drawings. The protection scope of the utility model claims.

Below in conjunction with accompanying drawing and embodiment the utility model patent is further described.

As shown in Figures 1-3, the utility model provides a current shunt for a power pipe female joint, which includes a pair of wire clips 1 and a wire 2 connecting the two wire clips 1. The wire 2 can be multiple The wire clamp 1 is composed of two parts, and when the two parts are spliced together, a cavity 12 is formed inside. The heating part of the pipe female joint often has a large resistance value, and the reliability of power supply cannot be guaranteed. However, the device is connected in parallel to the heating part of the pipe female joint. , thereby reducing the current value flowing through the body of the pipe female joint, the calorific value is reduced, and the heating defect of the pipe female joint is resolved. When the utility model is used to deal with the heating defect of the pipe female joint, live work can be carried out, so that the reliability of power supply is guaranteed. The utility model has the advantages of simple structure and convenient operation, and only needs to connect the utility model in parallel at both ends of the pipe female joints to be processed.

In order to more conveniently realize the purpose of eliminating the defect of the pipe female joint, the clamp 1 and the wire 2 are integrally formed, which effectively reduces the contact resistance, thereby reducing the loss of current.

Described wire clamp 1 is made up of two parts, and when two parts are spliced, a cavity 12 is formed inside it, and the shape of cavity 12 matches the shape of the outer wall of the described tube mother body. With such a design, during installation, only the two parts of the clamp 1 need to be sleeved on the two ends of the pipe female joint. In order to avoid the generation of corona, the two parts of the wire clip 1 are spliced to form a smooth transition profile. In addition, the embedded structure of the bolt 11 can also play this role.

In order to ensure the stretchability and flexibility of the wire, the wire 2 is made of aluminum, and the wire clamp 1 is made of aluminum alloy.

To sum up, the utility model is connected in parallel at both ends of the pipe female joint by means of bridging to deal with the problem of heating of the pipe female joint. The structure is simple and the operation is convenient. In addition, the cable clip 1 of the present utility model adopts a split design and is fixed with bolts 11, which is convenient for installation and maintenance. In addition, the outer contour design of the cable clip 1 adopts smooth and embedded bolts 11, which effectively prevents the generation of corona .

The utility model has been disclosed above with preferred embodiments, but it is not intended to limit the utility model, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation schemes all fall within the protection scope of the utility model.
