Purpose-made current guide plate and current guide method changing jumper current guide direction

Abstract

The invention discloses a purpose-made current guide plate and current guide method changing a jumper current guide direction. The purpose-made current guide plate is in associated use with a strain clamp current guide plate and a jumper current guide plate and includes an aluminum plate. The aluminum plate is provided with N connection holes, wherein N is a positive even number One half of the Nconnection holes are disposed on one end of the aluminum plate while the other half are disposed on the other end of the aluminum plate. The hole diameter and the hole distance of the connection holesare identical to the hole diameter and hole distance of connection holes of the strain clamp current guide plate and the jumper current guide plate. The current guiding method is characterized in that the strain clamp current guide plate is connected with the jumper current guide plate via the purpose-made current guide plate. The purpose-made current guide plate changing jumper current guide direction changes a current guide plate pre-offset value so as to made the value consistent with a design value generally, so that a condition that a jumper sub lead penetrates through or touches a leadvoltage sharing ring is avoided and circuit reliable and safe operation is ensured.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a special drainage plate and a drainage method for changing the drainage direction of a jumper wire. Background technique [0002] In the engineering practice of the construction of 500kV and above voltage transmission lines, due to the phase split of the conductors and the large cross-section and heavy load of the sub-conductors, it is often necessary to complete the crimping of the strain-resistant clamps, the lifting of the conductors and the completion of the metal insulator strings and jumpers. After the accessories such as wires are installed, the sub-conductors of the jumper need to pass through the conductor voltage-grading ring or touch the conductor voltage-grading ring or be very close to the conductor voltage-grading ring. Errors, construction crimping errors, etc. lead to a large difference between the pre-bias value of the strain clamp drainage plat...

Problems solved by technology

During normal operation, due to the influence of wind vibration, deicing and jumping and other operating conditions, there will be collision and friction between the jumper sub-conductor and the voltage equalizing ring. Long-term operation will damage the conductor voltage equalization ring and the jumper sub-conductor, which will affect the safety of the line. , Reliable operation brings hidden dangers
