Description
Technical field
The present invention relates to a kind of 10kV common-tower double-return line live-line work method, the charged upright iron tower operational method of particularly a kind of 10kV common-tower double-return circuit.
Background technology
Two distribution lines that return of wiring on the same tower are more and more in the application study in the city, compare with single back line, and it saves line channel more, and the iron tower height can be alleviated tree and line contradiction, Safe Vertical Distance when satisfying city overline bridge and overpass bridge and setting up.But it has also brought new problem, once a loop line road power failure operation needs double-circuit line to have a power failure simultaneously, thereby enlarges the power failure influence area.Therefore press for a kind ofly at the charged upright iron tower operational method of 10kV common-tower double-return circuit, realizing charging construction, not to be subjected to the restriction that has a power failure, reduction of erection time, quickening progress improve the method for power supply reliability greatly.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, and the restriction that provides a kind of and can realize charging construction, is not subjected to have a power failure, reduction of erection time, quickening progress improve the charged upright iron tower operational method of 10kV common-tower double-return circuit of power supply reliability greatly.
The objective of the invention is to be achieved by the following scheme:
The charged upright iron tower operational method of 10kV common-tower double-return circuit, its method is as follows, 1, the following joint and the middle joint of iron tower are installed, near the setting lead insulated cover, 2, save on the lifting iron tower, and will go up joint and fix with middle joint, 3, install two cross-arms in iron tower upper strata and insulator, and the insulation of carrying out cross-arm and insulator promotes the middle phase conductor of double-circuit line after covering and places on the insulator, and fixation will be restricted with insulating near the loop of iron tower inboard and will be temporarily fixed on cross-arm, install two cross-arms of lower floor and insulator again, and the insulation of carrying out cross-arm and insulator covers, and the more following layer conductor in the loop placed on the insulator fixingly, removes insulation and covers.
Because the distance between the double-circuit line of wiring on the same tower, the lead is short, in order to prevent that when the operation, lead rocks and causes phase fault, therefore need take insulation to cover near the lead the setting.For iron tower down joint and middle joint, because its top distance of wire distance surpasses the distance of " safety " regulation, so need not just cover and can assemble in advance lead.
Near the described setting wire insulation covers for adopting double insulation to cover.
Described double insulation covers for the mode that adopts wire insulation mask and insulated target to combine and carries out, and insulated target wraps in the outside of lead mask.
The wire insulation mask is the important insulating tool of isolated high-voltage trolley line, it has installs fast, convenient disassembly, advantage such as material is light, but there is potential discharge channel in wire insulation mask opening part, carries out double insulation so add the bag insulated target at the insulation mask.
Joint is slowly to be put down in the middle of the lead of double-circuit line by lead top on the described iron tower, to finish docking and fixing of joint and middle joint on the iron tower.
Described lead places the permanent order on the insulator fixing laterally by the iron tower inboard.
During operation, operating personnel and adjacent electrical body safe distance should keep 0.6m, should keep 0.4m with ground connector, will take the quarantine measures that insulate when not enough.
The lifting of iron tower adopts crane to carry out, and crane needs temporary grounding, and arm should keep 1.0m and above safe distance with electrical body all the time.
The personnel of high-rise working need put on the insulating protection apparatus, enter aerial lift device with insulated arm work.
When removing the insulation screening,, remove in proper order from high to low and cover by by as far as closely.
In sum, the invention has the advantages that:
Livewire work has not only improved power supply reliability but also has effectively reduced power off time, improves the economic benefit of power industry and other every profession and trade.The charged upright iron tower operational method of 10kV common-tower double-return circuit of the present invention, not only filled up domestic blank technically, and enterprise and society had a good economic benefit, 1, charged upright iron tower operation can increase distribution transforming, increase power supply capacity, the power supply area of common-tower double-return circuit is wide, raising along with the resident living level, power consumption is soaring year by year, each power office can only be by newly-increased distribution transforming to alleviate the situation of shortage of electric power, consider power supply reliability, the distribution transforming engineering can only be at the other upright iron tower of double-circuit line on the newly-increased bar in the past, and then receive on the double-circuit line iron tower by charged personnel T, this method takies unnecessary line channel, and it is big to implement difficulty, after promoting the charged upright tower of double-circuit line of wiring on the same tower, promptly can utilize original line channel project implementation simple, can avoid too much branch line to influence the city city appearance environment again, reduce maintenance cost.2, charged upright iron tower increases interconnection switch, the electrical network reliability is provided, along with urban development is more and more higher to the requirement of power supply reliability, increasing distribution network adopts structure structures such as () three segmentations, three contacts of multi-ring network formula, can increase block switch on the post by upright iron tower, interconnection switch is transformed traditional common ring web frame, improves the distribution reliability.3, charged upright iron tower T connects the service cable inlet wire, and the migration iron tower is widened a series of industries such as road surface and expanded engineerings can satisfy the large user under power-off condition not electricity consumption application, shortens industry and expands flow process.
