Description

Fixed interval (FI) overvoltage protection device built-in insulation device
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.

Embodiment
As shown in Fig. 1-6, a kind of fixed interval (FI) overvoltage protection device built-in insulation device, comprise by top electrode 2, resistor disc 4, the overvoltage protection device plug that middle electrode 5 and insulator 6 connect and compose from top to bottom successively, the surrounding of overvoltage protection device plug is coated with composite sheath 3, on middle electrode 5, level is installed a ball discharge I 7, insulator 6 is arranged on anti-slip support 9, on anti-slip support 9, be horizontally installed with the ball discharge II 8 coaxial with ball discharge I 7, the built-in inserts 10 in insulator top, described inserts 10 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 12 from the upper end of inserts, counterbore inwall is provided with internal thread 11, described insulator passes through screw flight close-coupled to anti-slip support.Distance between ball discharge I 7 and ball discharge II 8 is 35~50mm.
Described multiaspect column is four sides column, five columns, six columns, octahedral column or cylindrical.
In order to realize the sealing property of product after compression molding, be provided with the circular deep gouge 14 of a circle in the upper surface of described inserts 10.Insulator is designed to cylindric, is placed in overvoltage protection device bottom, completely cut off the inner current limiting element of overvoltage protection device and discharging gap, outside has composite sheath protection again.
For the one that realizes insulator and overvoltage protection device is connected, at the downward position, top of insulator 6, a deep-slotted chip breaker 13 is set.
Described inserts 10 adopts H59-62 brass or ferrous material to make, and process industrial art performance is good, intensity is high.
Described insulator adopts import glass fiber material to make, there is light weight, volume is little, impact good, machine commandment intensity is high, good insulation preformance and make simple advantage, and by insulator thermal endurance, mechanical property and the good weatherability of its making, especially it can form high strength key with the even oily metal surface of unclean surface, after being connected with composite sheath, can effectively prevent the infiltration of rainwater.
Inserts 10 integral die one-shot formings are installed into insulator.
In development process, test multiple insulation (son) material in laboratory, and the model machine of its manufacture is carried out to assessment test, and whether checking property indices can reach designing requirement.Participate in test insulator (material): porcelain insulator, with full skirt, not with full skirt, epoxy resin, epoxy glass fiber silk winding pipe and the every data of built-in inserts insulator (the utility model) are as following table;
When work, insulator turns the lower end that is arranged on middle electrode around, and copper conductor 1 connects the top electrode 2 of overvoltage protection device, in other end access transmission and distribution network.Top electrode 2 other ends are contact resistance sheet 4, middle electrode 5 and insulator 6 successively.Wherein middle electrode 4 studs with ball discharge I 7, as one end of discharging gap.Overvoltage protection device is fixed on anti-slip support 9 by insulator 6, and anti-slip support 9 vertical planes are provided with installing hole, and ball discharge II 8 can be installed, coaxial with ball discharge I 7, forms discharging gap, discharges the lightning current that overvoltage produces.
