Abstract

The utility model relates to an electrostatic high voltage liquid cable, an insulating layer is filled with special type liquid oil, the both ends are provided with transition joints, and the insulating layer is covered with a protective layer. The utility model has the advantages of flexibility, no breaking, light weight, low cost, convenient manufacture, convenient use, more than 150KV voltage and less than 1mA current, and the utility model can save a large amount of metallic materials. The utility model can be widely used in electrostatic devices such as electrostatic spraying paint, spraying powder, dust collection, etc.

Description

Electrostatic high voltage liquid cable

The utility model is a kind of high-pressure liquid cable that is used for static.

The electrostatic high-pressure cable that uses generally is to be made by multiply metal core outsourcing insulation at present, and what have also will add guard shield, and this high-tension cable plain conductor is more with material, the cost height, and hardness is big, and is crooked inconvenient during use, can rupture.

In view of the foregoing, task of the present utility model provides a kind of without plain conductor, low-cost, the liquid cable that uses in electrostatic high-pressure is carried.

The design of electrostatic high-pressure liquid cable is: be full of in tubular insulating barrier and contain the liquid fat that under high pressure can become the material of ion, have pair liquid fat to play the transition joint of sealing process, matcoveredn outside tubular insulating barrier at tubular insulating barrier two ends.Insulating barrier and protective layer are ambroin or electro-insulating rubber, and liquid fat can be the mixture of two or more liquid fat.Control can generate what of material of ion, can obtain the different resistivity of liquid fat.This cable uses in electrostatic apparatus, and its voltage is 100,000 so that more than 150,000 volts, and its electric current is in 1mA.

Use liquid fat to replace the liquid cable of multiply plain conductor, its weight saving, hardness are diminished, and save a large amount of raw material metals, its cost can reduce about half, this cable breaking phenomena can not occur simultaneously, and can be mixed with different conducting liquid greases according to different current requirements, to guarantee the constant current under constant voltage, realize its use in electrostatic apparatus such as electrostatic precipitation, electrostatic painting, electrostatic dusting.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a sectional structure chart of the present utility model.

Fig. 2 is the cross-sectional view of Fig. 1.

With reference to Fig. 1, Fig. 2, be full of the mixture of multiple liquid fat 1 in the tubular insulating barrier 2 of polyethylene from high pressure process, it contains metallic atom.The metal transfer joint 4 at tubular insulating barrier two ends and insulating barrier internal layer are for being threaded.The vandal-proof flame-proof polyvinyl chloride protective layer 3 of one deck in tubular insulating barrier 2 outsourcings.
