Electric current be up to kilo-ampere, therefore ground electrode circuit must use heat-resisting wire as carrier.The maximum of ground electrode circuit simultaneously
Working voltage is no more than 10kV, similar with distribution line.Examined during the tower head gap design of direct current grounding pole circuit by 35kV systems
Consider, tower body structure designs according to 220kV circuits.Because ground electrode circuit uses heavy in section double bundle conductor, conductor load weight, because
This strain insulator uses double structure, 5 insulators of often allying the communists.The minimum safe when carrying out livewire work on ground electrode circuit
Distance is 0.65 meter, when operating personnel's operation at the strain insulator near conductor wire end, operating personnel and recently powered
Only 1 meter or so of body, it is contemplated that 0.3 meter of physical activity scope, operating personnel and the clearance distance of ground potential component meet most reluctantly
Small safe distance, but gap very little.In order to ensure the safety of operating personnel, it is necessary to using insulated shielding cover to linear insulator
Insulation masking is carried out, and coordinates spacing fence limitation physical activity scope, operating personnel or instrument short circuit insulator is avoided or connects
Touch grounding body.
The content of the invention
The present invention is primarily directed to above mentioned problem, there is provided a kind of realize needs to carry out the difference of strain insulator according to maintenance
The insulation masking at position, while coordinate being reliably connected and enough coincidences between combined type magnetic position assurance difference mask
The earthing pole strain insulator mask of length.
The purpose of the present invention is mainly what is be achieved by following proposal：A kind of earthing pole strain insulator mask,
Including end mask, middle part mask and attachment means, described end mask includes section and covered in the end of U-typed
