Abstract
The utility model discloses a kind of fixed interval (FI) overvoltage protection device dedicated built-in insulating part, relate to a kind of voltage protector dedicated built-in insulating part.This invention has an insulator and is built in the inserts at insulator top, and inserts is wide at the top and narrow at the bottom, and inserts top is cylindric, bottom is multiaspect column, be provided with a ring annular groove one section, the centre of multiaspect column, have a counterbore from the upper end of inserts, counterbore inwall is provided with internal thread.Advantage: by screw flight close-coupled on the support of overvoltage protection device, avoids in the past built-in insulator strength inadequate, easily ruptures and connect not in place, situations such as destroying bottom insulation of leaking after leakage test.
Description
Technical field
The utility model relates to a kind of overvoltage protection device dedicated built-in insulating part, specifically single-minded kind of fixed interval (FI) overvoltage protection device dedicated built-in insulating part.
Background technology
At present, the mode of the outside connecting insulator of the many employings of a lot of overvoltage protection device is protected, and also has some overvoltage protection devices to adopt the insulator of built-in inserts in addition.Above-mentioned two kinds of modes are in assembling and install and use in process, and because built-in insulator strength is inadequate, easily rupture and connect not in place, leaking after leakage test affects bottom insulation.
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 dedicated built-in insulating part, and intensity is high, is not easy to tear.
The utility model schematically as follows technical scheme realize: a kind of fixed interval (FI) overvoltage protection device dedicated built-in insulating part; comprise an insulator and the inserts being built in insulator top; described inserts is wide at the top and narrow at the bottom; inserts top is cylindric; bottom is multiaspect column; be provided with a ring annular groove one section, the centre of multiaspect column, have a counterbore in the upper end of inserts, counterbore inwall is provided with internal thread.
The beneficial effects of the utility model are: the utility model passes through screw flight close-coupled on the support of overvoltage protection device; avoid in the past built-in insulator strength inadequate; easy fracture and connect not in place, situations such as destroying bottom insulation of leaking after leakage test.

Embodiment
As Figure 1-3, a kind of fixed interval (FI) overvoltage protection device dedicated built-in insulating part has an insulator 1 and built-in
In the inserts 2 at insulator 1 top, described inserts 2 is wide at the top and narrow at the bottom, and inserts top is cylindric, and bottom is multiaspect column, is provided with a ring annular groove one section, the centre of multiaspect column, has a counterbore 4 from the upper end of inserts, and counterbore 4 inwall is provided with internal thread 3.During work, by the insulator of built-in hexagonal insert by the support of screw flight close-coupled overvoltage protection device.
Described multiaspect column is four sides column, five columns, six columns, octahedral columns or cylindric.
In order to realize good seal performance, be provided with the circular deep gouge 6 of a circle in described inserts 2 upper surface.
Be connected with the one of overvoltage protection device miscellaneous part to realize insulator, a deep-slotted chip breaker 5 is set on the top of insulator 1.
Described inserts 2 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 be little, impact good, machine high, the good insulation preformance of commandment intensity and make simple advantage, and by its insulator thermal endurance made, mechanical property and good weatherability, especially it can form high strength key with the even oily metal surface of unclean surface, after being connected with composite sheath, effectively can prevent the infiltration of rainwater.
Inserts 2 is installed into insulator by integral die one-shot forming.
Participate in test insulator (material): porcelain insulator, band full skirt, not with full skirt, epoxy resin, epoxy glass fiber silk winding pipe and built-in inserts insulator (the utility model) every data as above show.
Claims (4)
