The adjustable link rod in a kind of top
Technical field
The present invention relates to technical field of electric power construction, particularly relate to the adjustable link rod in a kind of top.
Background technology
Along with social economy increases continuously and healthily, commercial power significantly increases, and all adopts the way of Voltage Power in delivery of electrical energy process for reducing electric energy loss.High voltage power transmission is a kind of mode by transmitting after the boost in voltage that exported by generator of generating station transformer.Why adopting transmission of electricity is in this way that the higher electric current of voltage is less because when same transmitted power, and such high voltage power transmission just can reduce electric current when transmitting electricity thus the thermal losses reduced because electric current produces and the material cost reducing long distance power transmission.High-tension electricity easily damages personnel and other life entity, and for protecting the life security of operating personnel, people use link rod to operate ultra-high-tension power transmission line.Link rod is also known as brake pull-rod, insulating rod, insulated tension pole.It is for closing or pulling open high voltage isolator, mounting or dismounting Portable ground wire, and uses when carrying out measuring and testing.10kV link rod also known as 10kV insulating bar, by working head, insulating bar and lever three part form, be insulating tool charging equipment operated for the short time.As closed or pulling open the aspects such as high voltage isolator, fuse switch, mounting or dismounting Portable ground wire.When adopting traditional 10KV link rod to falling type switch, vacuum switch operation, due to the operating space of the restriction such as weather effect and the order wire of erection around, dense branch or building staff, often cause the falling of cartridge fuse, vacuum switch decylization, unhook phenomenon, not only waste the operating time, compromise electric equipment, and increase the economic cost of distribution network line operation maintenance.
Traditional 10kV link rod caput is fixed, and caput operation part is smooth and be that cause can not the key of smooth operation without blocking mechanism, and the bad weather such as strong wind, thunderstorm is the main cause causing fault multiple, has very large impact to switch successful operation rate.
