Description

Bar shaped clamping wire type insulator

Technical field

The utility model relates to a kind of bar shaped clamping wire type insulator that can be used in fixing cord rope and conductive strips.

Background technology

Insulator is a kind of special insulation control, can in overhead transmission line, play an important role.In one's early years, insulator is used for electric pole, slowly develops into and hangs over the insulator that high type high-tension bus-bar connects one end of tower, and its effect is mainly in order to increase creepage distance, conventionally by glass or pottery, is made.Insulator is smooth, can reduce the capacitive reactance effect between electric wire, to reduce the loss of electric current.The various dynamo-electric stress that insulator should not change and cause due to environment and electric loading condition, insulator just can not produce great effect like this, thus the use of infringement whole piece circuit reduces service life.

In one's early years, insulator is used for electric pole, slowly develops into and hangs over the plate-like insulator that high type high-tension bus-bar connects one end of tower, and it is mainly in order to increase creepage distance, conventionally by glass or pottery, is made.Insulator plays two basic roles in overhead transmission line, support wire and prevent electric current return ground, these two effects must be guaranteed.

In order to prevent that the filths such as floating dust from adhering at insulator surface, form path and be insulated sub-both end voltage and puncture, creepage.Therefore increasing along the distance of insulating surface electric discharge is leakage distance, i.e. creep distance.Creep distance=surface distance/system ceiling voltage.Different according to pollution level, the general employing in heavy pollution area creep distance is 31 millimeters/every kilovolt.

The Potential distribution that zero resistance insulator refers to the insulator two ends that are in operation approaches zero or null insulator.

The impact of null value or low resistance insulator: the insulation of line conductor depends on insulator string, due to manufacturing defect or extraneous effect, the insulation property of insulator can be constantly deteriorated, is called low value or zero resistance insulator when insulation resistance reduces or be zero.According to recent detection, the ratio of null value or low resistance insulator is unexpectedly up to 9% left and right, and this is another main cause that lightning outage rate is high.

Domestic existing Jin200Duo Jia line insulator manufacturing enterprise, wherein has approximately 40 left and right of certain production-scale enterprise.Existing more than 100 countries adopt toughened glass insulator in the world, and quantity has surpassed 200,000,000.Due to power grid construction, accelerate, compare porcelain insulator, the development of domestic glass insulator is more swift and violent, and supply falls short of demand in its market, is constantly attracting other enterprises this field of competitively entering into.

The insulator that is applied at present fence field mostly is traditional model, can only be fixed and installation process complexity wire.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of bar shaped clamping wire type insulator is provided, and can be used for the fixing of conductor strip and conductive cords.

1. the purpose of this utility model is achieved through the following technical solutions: bar shaped clamping wire type insulator, it comprises the clamp that pedestal and tow sides all can be fixing with base combination, clamp is connected by connecting line with pedestal, respectively there is the column fixed leg of a hollow at clamp two ends, the metallic channel that has at least one between the fixed leg of two, the front of clamp has a conductive strips holddown groove between the fixed leg of two, the back side of clamp.

The one side that described pedestal contacts with clamp is provided with inner concave arc surface, and the reverse side of clamp is provided with the outer convex globoidal matching with this inner concave arc surface.

Respectively there is a counter sink corresponding with fixed leg at described pedestal two ends.

The beneficial effects of the utility model are: good looking appearance, and simple installation, dependable performance, clamp tow sides can be fixed respectively at base combination, and the insulation that can adapt to wire rope and conductive strips is fixed.
