Description

A kind of 500kV power transmission lines roadside phase conductor aerial lift device with insulated arm livewire work method
Technical field
The present invention relates to a kind of livewire work method of transmission line of electricity, a kind of 500kV transmission lines of electricity are concretely related to Side phase conductor aerial lift device with insulated arm livewire work method.
Background technology
Power industry maintenance repair, especially power transmission lines overhauling operation, operating personnel is typically necessary in wire or bar Work high above the ground is carried out on tower.The livewire work method of current 500kV circuits is based on idiostatic method, and operating personnel's climbing shaft tower is extremely At cross-arm near wire, equipotential operating point is entered by insulating ladder or hanging basket.If in carrying out operation, operation people in shelves Member needs to climb to operating point along wire.Because 500kV shaft towers are general all in more than 30m, circuit typical case's span is about 500m, larger Shaft tower size and line length bring very big difficulty into job position to operating personnel, operating efficiency is low, and risk is big.
It is presently available for the ascending tool mainly aerial lift device with insulated arm of high-altitude live-line maintenance operation.Livewire work is struggled against with insulation Arm car is to carry working bucket, insulation arm, the high-altitude operation vehicle of hydraulic control system, and falling from high altitude can be avoided into job position Danger, while reduce operating personnel labor intensity, improve operating efficiency, reduce operating risk.Aerial lift device with insulated arm exists It is widely used both at home and abroad, its insulating properties and mobility substantially increase the security and operating efficiency of operation.Insulation bucket arm Car is widely applied in China's 10kV power distribution live-wires, and there is no at this stage defeated in 500kV using aerial lift device with insulated arm The method that livewire work is carried out in electric line.
The content of the invention
Come it is an object of the invention to provide a kind of 500kV power transmission lines roadside phase conductor aerial lift device with insulated arm livewire work method For high-altitude live-line maintenance operation, the present invention is adopted the following technical scheme that:A kind of 500kV power transmission lines roadside phase conductor insulation bucket Arm car livewire work method, it is characterised in that comprise the following steps:
First it is grounded before SS1 aerial lift device with insulated arm operations, a full set of screening clothing of operating personnel's wearing climbs up working bucket, screening clothing Good electrical is carried out between working bucket with annealed copper wire to be connected;
Near human users' aerial lift device with insulated arm lift-off in SS2 buckets, manipulation working bucket to equipotential live line work position;
SS3 pause movements when 40 centimetres of working bucket distance of wire, operating personnel, which passes through electric potential transferring stick and completes current potential, to be turned Move;
Personnel carry out upkeep operation in SS4 operating personnels control working bucket contact live wire, bucket;
SS5 livewire work terminates, and operating personnel removes electric potential transferring stick and other all instruments, and operating personnel returns to ground Face.
Preferably, the aerial lift device with insulated arm is 500kV and above specification, and the working bucket is metal material It is made.
Preferably, the grounding rule of the aerial lift device with insulated arm described in the step SS1 is:Ground wire should be by minimum 4/0AWG's Soft copper cash is made, and ground distance is not more than 25cm, and grounding resistance is less than 25 ohm.
Preferably, the step SS2 also includes:When carrying out equipotential live line work, working bucket, live wire, operation should be kept Personnel three keeps good electrical connection to be in same current potential.
Preferably, the equipotential live line work position described in the step SS2 is the outside that operating personnel is located at wire, if Linear insulator operation nearby, then operating personnel head must be no more than edge on grading ring;The aerial lift device with insulated arm is mutually carried out on side Minimum safe distance is 3.4m over the ground during equipotential live line work, and alternate minimum safe distance is 5.0m.
The beneficial effect that the present invention is reached:(1)Equipotential electrician is directly entered 500kV circuits side by aerial lift device with insulated arm Job position in phase conductor shelves, without climbing shaft tower and being walked along wire, operation process is fool proof;(2)Use insulation bucket arm Car progress 500kV hot line maintenances are very efficient, compared to traditional work mode, terminate the activity duration more than 50%;(3) Labour needed for livewire work reduces operation is carried out using aerial lift device with insulated arm, operating personnel needed for this example is 3 people, is compared Traditional work method reduces the people of operating personnel 2.
