Description
Technical Field
The invention relates to a bypass operation and insulation short rod bridging method combined overhauling method used in the field of electric power engineering.
Background
At present, the uninterrupted operation project is mainly based on an insulating bucket arm vehicle and an insulating glove operation method. The operation safety is mainly based on the insulation shielding measures of the operators on the electrified bodies and the grounding bodies and the maintenance of the safety distance of the electrified bodies, and the reasonable selection of the working positions of the operators is depended. The personal experience and feeling becomes the subject of security at this time. Along with the promotion of company to the reliability requirement, use the bypass operation in large quantities in the engineering project and guarantee the power supply reliability, just as present, bypass operation intensity is big, and the risk is high, is unfavorable for developing on a large scale.
The traditional bypass operation needs to overhaul line equipment in multiple gears, and in order to ensure that a user who does not need to overhaul the line avoids power failure, a bypass operation method is adopted. It is common to find suitable straight pole segments at both ends of the line to be serviced and to install bypass systems on the outside. The traditional bypass operation mode is greatly influenced by equipment and construction environment. If the two ends of the maintenance line are not provided with proper straight rods, the power failure range can be expanded, and users who do not need power failure originally are forced to accompany and stop. Or the two ends of the electric pole are required to be erected again, and then the sections are opened, so that the operation difficulty and risk are increased.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a bypass operation and insulation short rod bridging method combined overhauling method, which can effectively reduce the risk of electric power construction operation and improve the efficiency.
One technical scheme for achieving the above purpose is as follows: a bypass operation and insulation short rod bridging method combined overhauling method comprises the following steps:
step 1, two operators carry an insulating short rod to enter an insulating hopper;
step 2, lifting the insulating bucket to the side lower part of the operation position of the target live-wire operation line;
step 3, an operator clamps the two insulated wire tighteners on the side phase conductor at the operation position, and the middle of the conductor is pulled oppositely;
step 4, respectively tightening the insulating tighteners of the two side phases by an operator, then cutting off the lead, and installing insulating jackets at the two ends of the cut-off lead;
step 5, the lead is in a loose state, and the insulation wire tightener is taken down;
step 6, synchronously and slowly loosening and removing the insulating rope by two operators respectively, and loosening and removing the conducting wire to two ends;
step 7, removing the wire clamp after the wires are removed;
and 8, descending the insulating bucket, and returning the operating personnel to the ground.
Further, all the operations of the operators, which are in contact with the conducting wire, are operated through the insulating short rod.
Compared with an insulating glove operation method, the bypass operation combined insulating short rod bridging method maintenance method ensures personal safety of the operators without directly contacting live equipment, greatly improves operation flexibility by matching the insulating short rod operation method with an insulating bucket arm vehicle, greatly shortens operation time due to no need of extra shielding in the operation process and the use of new tools, and is more convenient and flexible in bypass operation by matching with the bypass operation tools in complex live projects.
Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific examples:
the invention relates to a bypass operation and insulation short rod bridging method combined overhauling method, which comprises the following steps:
step 1, two operators carry an insulating short rod to enter an insulating hopper;
step 2, lifting the insulating bucket to the side lower part of the operation position of the target live-wire operation line;
step 3, an operator clamps the two insulated wire tighteners on the side phase conductor at the operation position, and the middle of the conductor is pulled oppositely;
step 4, respectively tightening the insulating tighteners of the two side phases by an operator, then cutting off the lead, and installing insulating jackets at the two ends of the cut-off lead;
step 5, the lead is in a loose state, and the insulation wire tightener is taken down;
step 6, synchronously and slowly loosening and removing the insulating rope by two operators respectively, and loosening and removing the conducting wire to two ends;
step 7, removing the wire clamp after the wires are removed;
and 8, descending the insulating bucket, and returning the operating personnel to the ground.
The bypass operation of the invention combines the operation mode of the maintenance method of the insulating short rod bridging method, can complete the disconnection operation of the lead in any wire rod, is not limited by equipment and construction environment any more, greatly shortens the radius of bypass laying, and does not have the problem of accompanying and stopping of non-maintenance users. Therefore, the insulating short rod bridging tool is combined with bypass operation, and is a huge supplement and promotion to the traditional bypass operation.
All the operations of the operators, which are in contact with the conducting wires, are operated through the short insulating rods.
It will be appreciated by those skilled in the art that the foregoing embodiments are provided merely for illustrating the invention and are not to be construed as limiting the invention so long as it is within the true spirit and scope of the invention.
