Consider, tower body structure is designed according to 220kV circuits.Since 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.
Utility model content
The utility model is primarily directed to the above problem, there is provided a kind of realize needs to carry out strain insulator according to maintenance
The insulation masking of different parts, while coordinate being reliably connected between combined type magnetic position assurance difference mask and enough
Overlap the earthing pole strain insulator mask of length.
The purpose of this utility model is mainly what is be achieved by following proposal：A kind of earthing pole strain insulator masking
Cover, including end mask and middle part mask, the end mask include the end mask master that section is in U-typed
Body, end mask hush panel, retainer ring and some end mask magnet, the end mask hush panel are arranged on end
Portion mask main body one end, is provided with strip gab groove, the end mask magnetic in the end mask hush panel
Iron is arranged on two side external surface of end mask main body, and the retainer ring is arranged in the mask main body of end, in described
Portion's mask includes middle part mask main body, holding ring and the middle part mask magnet that section is in U-typed, middle part masking
Cover body inner surface coordinates with the end mask body outer surface to be slidably connected, and the middle part mask magnet is set
At middle part, mask main body both sides inner surface is engaged with end mask magnet, and the holding ring is arranged on middle part mask
In main body, the end mask and middle part mask are flame-retardant insulating material.Middle part is hidden using holding ring during use
The release of cover main body is covered, after being pushed out to a distance, end mask magnet and middle part mask magnet attract each other and middle part hidden
The relative position for covering cover main body and end mask main body is positioned.
Preferably, it is additionally provided with limiting groove, the middle part on the end mask main body top upper surface
It is additionally provided with the lower surface of mask main body top and the matched limited block of the limiting groove.Limiting groove and limited block
Design can make middle part mask main body slide in a specified direction.
Preferably, it is additionally provided with roller on the limited block.Roller can make cunning of the limited block in limiting groove
Dynamic friction is changed into rolling friction.
Preferably, the connection on described connecting plate one end and middle part mask main body top is to be bolted.Bolt connects
Connect and be readily disassembled, basic without under the operating condition of vibrations, it is higher to be bolted sexual valence.
Preferably, the limiting groove section is in isosceles trapezoid.The design of isosceles trapezoid can hide middle part
Cover cover main body and not readily disengage from end mask main body.
Preferably, it is additionally provided with retainer ring in the end mask main body.During portion's mask main body on the move,
With retainer ring compressing to shaded thing can be reduced to fix end mask main body.
