Abstract

The utility model discloses a pin-type insulator which consists of a porcelain insulator and a fixed screw rod which is fixed on the porcelain insulator. The upper end part of the porcelain insulator is provided with a wire channel. The top of the fixed screw rod is in a smooth spherical structure. A part, which is connected with the fixed screw rod, in the porcelain insulator is also in a spherical structure. The smooth spherical design can enable an electric field between the wire and the fixed screw rod to be distributed uniformly, thereby reducing the possibility of breakdown of the porcelain insulator, and avoiding breakdown caused by excessively strong local electric field. When the insulator is installed on a power transmission and distribution line, the insulator can greatly improves the supply reliability, reducing the times and duration of a power failure, and produces great economic benefits and social benefits.

Description

Pin insulator
Technical field
The utility model relates to transmission line technical equipment field, particularly relates to a kind of pin insulator.
Background technology
Pin insulator is a kind of force device conventional in electric power system, is usually used in high and low pressure transmission line, supports and fixing cord.In the time that high and low pressure transmission line sets up, conventionally be all to adopt aluminium wire that wire is banded on porcelain insulator, the screw rod of porcelain insulator is fixed on cross-arm, between wire and standing screw, there is very high voltage, because the top of original standing screw is all more flat cylinder cross section, under High Pressure, the edge and corner position of cylinder can produce very strong electric field, larger in the situation that, often there is the breakdown situation of insulator in thunderstorm weather or change in voltage.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of pin type insulator, and it has overcome between wire and standing screw, due to non-uniform electric, causes local location electric field strength excessive, easily punctures the problem of insulator.
The technical scheme that the utility model adopts is: it is made up of porcelain insulator and the standing screw that is fixed on porcelain insulator, porcelain insulator upper end offers metallic channel, the top of standing screw is smooth spherical structure, in porcelain insulator and standing screw junction, also be spherical structure, and both fit like a glove.
The beneficial effects of the utility model are: this smooth sphere design, and can make the electric field between wire and standing screw be uniformly distributed, reduce the breakdown possibility of porcelain insulator, avoid crossing because of internal field the punch-through causing by force; While being arranged on electric line, can greatly improve power supply reliability, reduce frequency of power cut and interruption duration, create huge economic benefit and social benefit.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below by drawings and Examples, the utility model is further described.
As shown in Figure 1, it is made up of porcelain insulator and the standing screw that is fixed on porcelain insulator, and porcelain insulator upper end offers metallic channel, the top of standing screw is smooth spherical structure, in porcelain insulator, with standing screw junction, be also sphere 4 structures, and both fit like a glove.
This pin insulator, by being bolted on cross-arm under standing screw 1, use aluminium wire that wire is banded in the groove 5 on porcelain insulator 3, although there is very high voltage between wire and standing screw, but because the top 2 of standing screw 1 is more smooth sphere, between wire in groove 5 and standing screw 1, have a more uniform electric field, be difficult to occur again the breakdown situation of insulator.

Claims (1)

1. a pin insulator, it is made up of porcelain insulator and the standing screw that is fixed on porcelain insulator, porcelain insulator upper end offers metallic channel, it is characterized in that: the top of standing screw is smooth spherical structure, in porcelain insulator and standing screw junction, also be spherical structure, and both fit like a glove.
