Each of the metal hooks is provided with two contact annealed copper sheets for clamping wires. Connection; when entering the equipotential, use the metal hook with the opening facing the rear end of the insulating handle to hook the wire, so that the metal hook and the wire are fully in contact to ensure safety and ensure the safety of the process of entering the equipotential. When withdrawing from the equipotential, the main wire is clamped by the metal hook with the opening of the potential transfer rod facing the front end of the insulating handle, and the equipotential can be withdrawn by pulling it backward. Avoid the wire being too close to the operator and eliminate potential safety hazards. This process is completed by the new bidirectional potential transfer rod. The process of entering and exiting the equipotential is safe and reliable, and the operation is convenient to ensure the safety of the operator.

Description

A Bidirectional Potential Transfer Rod

technical field

The utility model belongs to the technical field of maintenance of ultra-high voltage and extra-high voltage transmission lines, and relates to a bidirectional potential transfer rod.

Background technique

Live work has become an important means and method of power line detection, maintenance and transformation, and plays a very important role in the safe and reliable operation of the power system and the improvement of economic benefits. Entering the equipotential is an important work step in the live operation of the transmission line, which is directly related to the safety of the operator and the efficiency of the operation.

At present, there are many types of tools used in live work, and the structure is very different. Their performance is directly related to the safety of operators and equipment. Therefore, the management and use of insulating tools and safety protection equipment must comply with the "State Grid Corporation Electric Safety Work Regulations ( Line part) ", strictly abide by the regulations in the safety regulations, conduct regular tests, and find out the existing defects and hidden dangers in time.

Potential transfer rod is a metal tool used by equipotential operators when entering and exiting equipotentiality. It is used to reduce the impact of discharge arc on human body and avoid possible damage to shielding clothing caused by pulse current. The existing potential transfer rod structure only has a hook-shaped chuck facing one end of the insulating handle, and the equipotential operator uses the chuck to hook the wire when entering the equipotential; but when exiting the equipotential, the potential transfer rod needs to move forward in the direction of the wire It can only be removed by pushing a large stroke, which leads to the short distance between the equipotential operator and the charged body, which has great potential safety hazards and is extremely inconvenient to operate.

Utility model content

In order to solve the defects of the prior art, the purpose of the utility model is to provide a convenient, safe and reliable bidirectional potential transfer rod.

In order to achieve the above object, the utility model adopts the following scheme:

A bidirectional potential transfer rod, including an insulating handle, a hook-shaped chuck fixed on the front end of the insulating handle, the hook-shaped chuck is composed of two U-shaped metal hooks with opposite openings, one metal hook opens toward the rear end of the insulating handle, The opening of the other metal hook is towards the front end of the insulating handle. Two contact annealed copper sheets for clamping wires are arranged in each of the metal hooks, and the middle part of each contact annealed copper sheet is connected to the inner wall of the metal hook by a compression spring.

Further, the contact annealed copper sheet is semicircular, and the middle part of the annealed copper sheet is provided with a depression for accommodating wires.

Further, the two U-shaped metal hooks adopt an integral structure made of copper material.

Further, the insulating handle is covered with a rubber sleeve.

Further, the length of the insulating handle is 50cm.

Further, the insulating handle is provided with multiple strands of copper wires connected with metal hooks.

The utility model bidirectional potential transfer rod, the hook-shaped chuck is composed of two U-shaped metal hooks with opposite openings, one metal hook opens towards the rear end of the insulating handle, and the other metal hook opens towards the front end of the insulating handle, which is used when entering the equipotential The metal hook with the opening facing the back end of the insulating handle hooks the wire, so that the metal hook and the wire are fully in contact to ensure safety and the process of entering the equipotential; , the operator manually adjusts the connection method between the potential transfer rod and the main wire so that the metal hook with the opening facing the front end of the insulating handle clamps the main wire, and then the human body shielding suit is separated from the main wire, and only the potential transfer rod and the charged body are kept at the same potential . Pull the insulated handle backward to separate the potential transfer rod from the wire, avoid the wire being too close to the operator, eliminate potential safety hazards, and ensure the safety of the process of personnel exiting the equipotential. The whole process can be completed by using a new bidirectional potential transfer rod. The process of entering and exiting the equipotential is safe and reliable, and the operation is convenient to ensure the safety of operators.

Further, the contact soft copper sheet is semicircular and the middle part of the soft copper sheet is provided with a depression to accommodate the wire. When the metal hook hooks the wire, it is stuck in the two contact soft copper sheet depressions to ensure reliable contact between the copper sheet and the wire and ensure safety. .
