For making insulating sleeve have good insulation property, pliability is high and in use indeformable, and described top insulating sleeve and bottom insulation sheath material are fluid silicone rubber.
Top insulating sleeve opening, when assembling, is broken into two with one's hands and is sleeved on lightning arrester body top, being contained in sleeve pipe simultaneously, then backing plate being touched flange portion by top high-voltage cable joint-box by electric locomotive lightning arrester of the present utility model, with bolt, flange portion is fastening;
When bottom insulation sheath is installed, its opening is broken into two with one's hands, be sleeved on bottom lightning arrester body, and earth connection is arranged in hollow boss, then backing plate is touched flange portion, with bolt, flange portion is fastening.
Remarkable result of the present utility model is:
1. be arranged on the insulation protective jacket of lightning arrester body top and bottom; the electric connecting member at lightning arrester body top and the mechanical mounting portions of bottom are protected simultaneously; greatly can improve the creepage distance of lightning arrester and roof; protection high-tension cable connecting portion is not by environmental pollution, and antifog (dirt) that improve locomotive dodges performance.
2. the insulation protective jacket of this silastic material, has good hydrophobicity and insulation property, prevents sleet gathering on high-tension apparatus, long service life
3. the integrative-structure design of open type, makes dismounting overhaul convenient; The structural design of flange, makes it have good sealing.
4., owing to devising cyclic reinforcing rib in cylindrical sleeve and tubular casing outer surface, the structural strength of cylindrical sleeve and tubular casing is strengthened; Meanwhile, this cyclic reinforcing rib can be practical as full skirt, strengthens the creepage distance of cylindrical sleeve and tubular casing.
