The utility model discloses a rod-shaped insulator used for low-voltage lines, which comprises a rod-shaped insulator and two metal caps respectively sleeved on two ends of the insulator. The outer end of each metal cap axially extends outwards with a pair of Each pair of ear clips is provided with a pair of perforations, and the middle part of the insulator is provided with two-layer umbrella ribs with a distance of 25-29 mm. The diameters of the two-layer umbrella ribs are both 90-94 mm. The utility model has low manufacturing cost and sufficient creepage distance, and is suitable for large-scale application.
Description
Technical field
The utility model relates to a kind of insulator, relates in particular to a kind of rod insulator for low-voltage circuit.
Background technology
Insulator is mainly used in the defeated modified line of high and low pressure road, plays insulation and supporting function.At present, what extensively use on the defeated modified line of low pressure road is generally the rod insulator insulator, and it has lot of advantages, such as: size is little, lightweight, the life-span long, need not detect null value, self-cleaning is good etc.But existing rod insulator for the defeated modified line of low pressure road arranges the umbrella rib of the too much number of plies in order to increase creepage distance, makes its high cost, causes great waste after large-scale application.But, if make creepage distance inadequate, can cause again the security incidents such as line tripping, be unfavorable for the safe operation of low-voltage circuit.Therefore, the manufacturing cost of as far as possible dwindling insulator under the prerequisite that guarantees creepage distance is the problem that needs solution.
Summary of the invention
The purpose of this utility model is to provide a kind of two-layer umbrella rib, manufacturing cost is lower and have the rod insulator that is used for low-voltage circuit of enough creepage distances.
The technical scheme that realizes above-mentioned purpose is:
A kind of rod insulator for low-voltage circuit comprises the insulator of clavate and is socketed in respectively two metal caps at this insulator two ends that the outer end of each metal cap axially is outward extended with a pair of ear and climbs, and every pair of ear is climbed up and is provided with a pair of perforation,
The middle part of described insulator is provided with two layers of umbrella rib that spacing is 25 ~ 29mm, and the diameter of these two layers of umbrella ribs is 90 ~ 94mm.
The above-mentioned rod insulator that is used for low-voltage circuit, wherein, the spacing between described two layers of umbrella rib is 27mm; Described two layers of umbrella rib diameter separately is 92mm; The diameter of described insulator is 50 ~ 60mm.
The above-mentioned rod insulator that is used for low-voltage circuit wherein, bonds by cement glue between the inner surface of described metal cap and the end outer surface of described insulator, and is provided with pad between the crown position of this cement glue and described metal cap.
The above-mentioned rod insulator that is used for low-voltage circuit, wherein, the diameter of described insulator is 53mm.
The above-mentioned rod insulator that is used for low-voltage circuit, wherein, described insulator is ceramics insulator.
The above-mentioned rod insulator that is used for low-voltage circuit, wherein, described insulator is glass insulator.
The beneficial effects of the utility model are: the utility model arranges two-layer umbrella rib, and the diameter of this two-layer umbrella rib and the spacing between them have been stipulated, make insulator keep enough creepage distances on the basis of saving manufacturing cost, can save great amount of cost after large-scale application, have the real economy benefit.
Description of drawings
Fig. 1 is the structural representation of the rod insulator for low-voltage circuit of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, rod insulator for low-voltage circuit of the present utility model, comprise the insulator 1 of clavate and be socketed in respectively two metal caps 2 at insulator 1 two ends, the outer end of each metal cap 2 axially is outward extended with a pair of ear and climbs, every pair of ear is climbed up and is provided with a pair of perforation, every pair of perforation is used for straight pin 5 is installed, and makes the utility model be arranged on easily various occasions;
The diameter d of insulator 1 is 50 ~ 60mm, the middle part of insulator 1 is provided with two layers of umbrella rib that spacing I is 25 ~ 29mm, makes insulation air line distance L elongate and reach 80 ~ 90mm, and two layers of umbrella rib diameter D separately are 90 ~ 94mm, make creepage distance can reach 120mm, meet the requirement of low-voltage circuit; In the present embodiment, the spacing I between described two layers of umbrella rib is 27mm; Described two layers of umbrella rib diameter D separately is 92mm; Insulator 1 is ceramics insulator or glass insulator, and its diameter d is 53mm.
By cement glue 3 bonding, and be provided with pad 4 between the crown position of this cement glue 3 and metal cap 2 between the end outer surface of the inner surface of metal cap 2 and insulator 1, avoided insulation to produce the possibility of null value; In the present embodiment, cement glue 3 adopts high strength cement compo, and pad 4 is felt paper.
Above embodiment is only for illustration of the utility model, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that do not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
