Quick hot-line by-pass jumper overlapping operation method for 10kV insulated power distribution line

Abstract

The invention provides a quick hot-line by-pass jumper overlapping operation method for a 10kV insulated power distribution line. The operation method is cooperatively implemented by a work leader, an on-post ground potential operation electrician and two ground operation electricians. A ground potential operation method is adopted and mainly comprises the operation steps of applying for stopping using re-closing equipment, taking insulation isolation measures, making a preparation for overlapping, stripping off a middle phase conductor insulating layer, overlapping a middle phase joint, overlapping two side phase joints, removing insulation isolation measures, restoring the re-closing equipment of the line and the like. The quick hot-line by-pass jumper overlapping operation method for the 10kV insulated power distribution line has the advantages that the operation method is convenient, quick, time-saving and labor-saving, the working efficiency can be greatly improved, the limitations and the defects of the traditional direction operation methods by using an aerial lift device with an insulating arm and insulating sleeves are overcome, the reliability of power supply guarantee is improved and the range of hot-line operation items of a power distribution network is widened.

Description

technical field [0001] The invention relates to the technical field of live operation of 10kV overhead power distribution insulated lines, in particular to an operation method for rapidly live-lapping drain wires of 10kV power distribution insulated lines by adopting a ground potential operation method. Background technique [0002] At present, the method of lapping and dismantling the insulated wire branch and drain wire for the 10kV overhead power distribution insulated line is usually carried out by using an insulated bucket truck to lift the operator to a suitable working position. The operator is on the insulated bucket truck Use insulated gloves to work directly inside, and carry out lapping or removal of branch drain wires of insulated wires. However, with the widespread setting of green belts on both sides of urban roads and the restrictions on the passage of vehicles on the platform of residential quarters, high-voltage user entry poles, and country roads in the sub...

AI Technical Summary

Problems solved by technology

However, with the widespread setting of green belts on both sides of urban roads and the restrictions on the passage of vehicles on the platform of residential quarters, high-voltage user entry poles, and country roads in the suburbs, the rush repair of line equipment in such areas is limited due to the entry of insulating bucket trucks. Therefore, it cannot fully meet the needs of emergency repair operations; in addition, due to the increasingly scarce line channel resources in urban areas, the structure of overhead distribution lines is becoming increasingly complex and compact, such as high and low voltage poles or multi-circuit erection on the same pole. , making the gap between the lines smaller and smaller. If the direct operation method of insulating bucket arm truck with insulating gloves is used, the operator needs to directly contact the wires. The smaller and smaller turning space between the complex line structures on the overhead line will give Operators pose a greater safety risk

However, with the increasing insulation rate of distribution lines, there are more and more operations to dismantle insulated wires and connect drain wires. It is difficult to meet the requirements of production and life by relying only on the current direct operation method of insulated bucket trucks and insulated gloves. Therefore, a new method of lapping and removing the insulated wire branch connection and drain wire is sought for a new 10kV overhead power distribution insulated line, which can be used when the direct operation method of the commonly used insulated arm truck and insulated gloves is inconvenient. It is very necessary to quickly connect and remove the insulated wire branch connection and drain wire to effectively ensure the power supply
