Problems solved by technology

In this case, due to various factors such as personnel, spare parts, and construction environment, it is often impossible to deal with the faulty equipment in time, or even if someone is sent to deal with it, it is often necessary to cut off the electricity for a long time without emergency measures. In one case, it is urgent to design emergency line jumpers that can be operated by operating personnel

Embodiment Construction

[0017] Such as figure 1 Shown, a kind of line spanning method, it comprises the following steps:

[0018] a. Select the crossing line and prepare the corresponding line crossing tool;

[0019] b. Take measures to electrify both the substituting line and the substituting line;

[0020] c. After checking that the phase color marks of the two lines are correct, do not select the cross-connection line of the corresponding color, install phase A, phase B, and phase C one by one, and connect the insulation rod to the cross-connection line. When installing, the opening of the clamp is facing downward. Tighten the straddle clips.

[0021] d. Check that the phase sequence on both sides of the installed cross-connection is correct, there is no residue, and the connection of the cross-connection clip is fastened without looseness.

[0022] The distance between A, B, and C is kept at 80 cm and there is no possibility of collision with each other;

[0023] e. Remove the safety measures...

Abstract

The invention discloses a new line bridging method and a special bridging line. The special bridging line comprises three bridging units and a special bridge insulating rod, wherein each bridging unit comprises two fixed line clamps which are connected with a line; the bridging line is arranged between the two fixed line clamps; and the special bridge insulating rod is movably connected with the lower ends of the fixed line clamps. The line bridging method and the special bridging line can meet the requirements of bridging of lines of 110KV or less. A device has light weight and high universality, can be conveniently and flexibly operated and is safe to bridge, does not have hidden trouble, and is easy and convenient to transport, assemble and store. Working personnel do not need to work high above the ground. The structure of the bridging device does not have influence on other running equipment and has a broad operating range.

Description

technical field [0001] The invention belongs to the technical field of electric power operation, and relates to a jumper connection method for power transmission and distribution lines up to and including 110KV and a special jumper wire. Background technique [0002] In the power operation link, users are often forced to cut off power due to failure or damage of primary equipment such as high-voltage circuit breakers, high-voltage isolation switches, and voltage transformers on the power supply side or load side of power equipment. In this case, due to various factors such as personnel, spare parts, and construction environment, it is often impossible to deal with the faulty equipment in time, or even if someone is sent to deal with it, it is often necessary to cut off the electricity for a long time without emergency measures. In one case, it is urgent to design an emergency circuit jumper that can be operated by operating personnel. Contents of the invention [0003] Th...
