Description
Technical field
The utility model relates to overvoltage protection device insulator arrangement, specifically a kind of fixed interval (FI) overvoltage protection device built-in insulation device.
Background technology
What similar thunder resisting equipment adopted in the past is while connecting outside fixed interval (FI), must use external insulator (support) to completely cut off body and discharging gap, so just cause in assembling and install and use in process, it is aging, out of service very soon easily to there is fracture and ultraviolet radiation in external insulator (support).
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of fixed interval (FI) overvoltage protection device built-in insulation device, not easy fracture.
The utility model is realized with following technical scheme: a kind of fixed interval (FI) overvoltage protection device built-in insulation device, comprise by top electrode, resistor disc, the lightning arrester plug that middle electrode and insulator connect and compose from top to bottom successively, the surrounding of lightning arrester plug is coated with composite sheath, on middle electrode, level is installed a ball discharge I, insulator is arranged on anti-slip support, on anti-slip support, be horizontally installed with the ball discharge II coaxial with ball discharge I, the built-in inserts in insulator top, described inserts is wide at the top and narrow at the bottom, inserts top is cylindric, bottom is multiaspect column, in the centre of multiaspect column, one section is provided with a ring annular groove, have a counterbore from the upper end of inserts, counterbore inwall is provided with internal thread, described insulator passes through screw flight close-coupled to anti-slip support.
The advantage of the utility model patent: abandoned original external insulator (support) structure, adopted built-in insulation structure, avoided the easy fracture of external insulator (support) in the past and ultraviolet radiation aging, situation out of service fast.
