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

Abstract

The invention provides a quick hot-line by-pass jumper removing operation method for a 10kV insulated power distribution line. The operation method is 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, making insulation isolation measures, removing one side phase by-pass jumper, taking insulation isolation measures at a removing position, removing the other side phase by-pass jumper, removing a middle phase by-pass jumper, detecting and fixing the removed by-pass jumpers, removing an insulating device, restoring the re-closing equipment of the line and the like. The quick hot-line by-pass jumper removing 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 work on 10kV overhead power distribution insulated lines, in particular to an operation method for rapidly live-dismantling drain wires of insulated lines during ground potential work. 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 suburbs, the rush repair of line equipment in s...

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 s...
