Description
Technical field
The present invention relates to change insulator chain aid technical field, be specifically related to a kind of for the insulation of 500kV strain insulator
Manned dolly on substring.
Background technology
In hot line maintenance, livewire work personnel enter highfield according to job task and are operated, i.e. people
Body contacts with electrical body, constitutes isoelectric level body.Enter at present the method for highfield mainly have insulated flexible ladder method, insulated ladder method,
Insulation hard ladder method, hanging basket method and enter method along insulator chain.Insulated flexible ladder method is to hang on wire or ground wire by ladder head, operation
Personnel climb position, operating point along rope ladder.Insulated ladder method is mainly used in 110kV and 220kV hot line maintenance, ladder
Head hangs on wire, and ladder tail is fixed on tower body, and operating personnel is sitting in ladder and slowly moves to live end from earth terminal.Insulation
Hard ladder method is similar with insulated flexible ladder method, when line conductor distance to the ground ratio is relatively low, accomplishes fluently earth anchor on ground, assembles vertical ladder, and
Tying up stay cord, operating personnel climbs to position, operating point along hard ladder.Hanging basket method is to tie up on cross-arm with an insulating cord, equipotential live line work
Personnel are sitting in hanging basket, and Ground Operation personnel draw insulation ropes, isoelectric level personnel are sent in highfield.Enter along insulator chain
Method refers to that equipotential live line work personnel enter wire process along strain insulator string from cross-arm, and human body trick is entered by across two short three modes
OK, must not random short circuit insulator, in order to avoid causing good insulation sub-pieces number and combinational gap inadequate.
The method that highfield is entered in existing livewire work is the most, but all having some limitations property.Insulated flexible ladder method is suitable for
In the lead wire and earth wire livewire work of differing heights, but higher to operating personnel's competency profiling, and operating personnel has to pass through specialty
Climbing training, and process of climbing also is a test the biggest to the muscle power of operating personnel.Insulated ladder method is applicable to 110kV
With 220kV hot line maintenance, in super extra-high voltage electrified operation, wire is distant with tower body, should not use, and
Insulator is not easy to carry.Insulation hard ladder method is applicable under the operating mode that wire distance to the ground is smaller, and carries inconvenience.Hang
Basket method is mainly used in tangent tower, needs the several operating personnel in ground to coordinate and equipotential live line work people personnel is sent in highfield.Edge
Insulator chain enters method and is mainly used in entering in highfield along strain insulator.Along with the height of electric pressure, UHV transmission
Line tension insulator reaches 80 multi-discs, then to enter highfield along insulator chain in the way of two short three, the most time-consuming, and
It it is a test the biggest to operating personnel's physical ability.For above not enough, the present invention designs a kind of human body and enters electric field with sitting posture
Dolly, facilitate equipotential live line work personnel to enter highfield along strain insulator string.
Summary of the invention
