Abstract

The utility model discloses a high-voltage creepage-prevention conductive pole. The high-voltage creepage-prevention conductive pole includes a conductive pole body; the external side of the conductive pole body is wrapped with a creepage-prevention mechanism; the creepage-prevention mechanism is composed of elastic protection bowls, a hard sheath, an elastic sheath and an outer wrapping protective film; the exterior of the conductive pole body is wrapped with the hard sheath; the external side of the hard sheath is wrapped with the elastic sheath; the external side of the elastic sheath is wrapped with the outer wrapping protective film; the elastic protection bowls are arranged at two ends of the conductive pole body; the tail ends of the elastic protection bowls are clamped between the hard sheath and the elastic sheath; a conductive paste player with uniform thickness is arranged between the hard sheath and the conductive pole body. With the high-voltage creepage-prevention conductive pole of the utility model adopted, the insulation performance of the conductive rod itself can be greatly improved, and at the same time, the generation of creepage phenomenon can be effectively eliminated, and therefore, the stability and security of the operation of the conductive rod can be greatly increased; and further, with a multilayer-insulator assembled type structure adopted, anti-natural corrosion and external shock-prevention performance of an insulation layer can be greatly increased, and therefore, the the service life of the conductive rod can be greatly prolonged, and power supply cost reduction can be facilitated.

Description

A kind of high pressure anti-tracking conducting rod

Technical field

This novel a kind of high pressure anti-tracking conducting rod, genus high-voltage transmission equipment technical field of relating to.

Background technology

In high voltage power transmission field, in the connection of high-tension electricity, quite a few is to realize by conducting rod, , as being connected between transformer coil and binding post etc., how the conducting rod using is at present made by conducting metal, then at its outer surface spraying one deck coatings, but due in high-voltage connection, very easily on insulator outer wall, there is creepage phenomenon, when having electric conductor apart from conducting rod close together, creepage phenomenon very easily causes conducting rod to external current conductor electric discharge phenomena, thereby cause sparking, connecting the faults such as electricity even opens circuit occurs, serious threat to conducting rod useful life with regard to power supply safety, simultaneously because traditional coatings is for being sprayed on conducting rod, therefore easily there is the inhomogeneous or drain spray phenomenon of spraying, coatings in spraying simultaneously, also very easily because of external force or spontaneous corrosion, come off, thereby cause conducting rod insulating capacity to decline, more aggravated sparking, connect the generation of the phenomenons such as electricity, also more can aggravate the aging of insulating barrier simultaneously, and the generation of the phenomenon such as corrosion, finally cause aggravating the loss of conducting rod, greatly reduce the Acceptable life of conducting rod, improved the operating cost of electric power system, serious threat power supply safety.

Summary of the invention

This novel object is just to overcome above-mentioned deficiency, and a kind of high pressure anti-tracking conducting rod is provided.

For achieving the above object, the present invention is achieved through the following technical solutions:

A kind of high pressure anti-tracking conducting rod, comprise conducting rod body, the another anti-tracking mechanism that is coated in described conducting rod body outside, described anti-tracking mechanism protects bowl by elasticity, hard sheath, flexible sheath and cover outward diaphragm form, described hard sheath is coated on conducting rod, and this is external, and hard jacket thickness is 1 millimeter-3 millimeters, described flexible sheath is coated on hard sheath outside, thickness is 3 millimeters-5 millimeters, and outer surface is corrugated or uniform hemispherical projections, the described outer diaphragm that covers is coated on flexible sheath outside, its thickness is 0.5 millimeter-2 millimeters, described elasticity is protected bowl and is positioned at conducting rod body two ends, and be connected with conducting rod body by screw, between the another folder of its end and hard sheath and flexible sheath, described elasticity is protected on bowl separately at least uniform 4 osculums, and inwall is not less than 3 centimetres apart from conducting rod body distance, the conductive paste layer of even thickness is separately set between described hard sheath and conducting rod body.

Hard sheath material is insulating ceramics or bakelite.

Elasticity is protected bowl and flexible sheath material is electro-insulating rubber.

Covering diaphragm is outward isolating shrinkable film or isolating shrinkable tube.

This novel employing multilevel insulator modular construction substitutes traditional spraying insulating barrier, on the one hand when greatly having improved the insulation property of conducting rod self, also effectively stopped freeing of creepage phenomenon, stability and the fail safe of conducting rod operation have been increased greatly, multilevel insulator modular construction has also increased the anti-spontaneous corrosion of insulating barrier and the ability of foreign impacts greatly simultaneously, also for conducting rod has improved better safety assurance, thereby greatly extended the useful life of conducting rod, contributed to reduce power supply cost.

Accompanying drawing explanation

Fig. 1 is this new structure schematic diagram.

Embodiment

As shown in Fig. 1, a kind of high pressure anti-tracking conducting rod, comprise conducting rod body 1, described conducting rod body 1 outside is separately coated anti-tracking mechanism, described anti-tracking mechanism protects bowl 2 by elasticity, hard sheath 3, flexible sheath 4 and cover diaphragm 5 outward and form, described hard sheath 3 is coated on outside conducting rod body 1, and hard sheath 3 thickness are 1 millimeter-3 millimeters, described flexible sheath 4 is coated on hard sheath 3 outsides, thickness is 3 millimeters-5 millimeters, and outer surface is corrugated or uniform hemispherical projections, the described outer diaphragm 5 that covers is coated on flexible sheath 4 outsides, its thickness is 0.5 millimeter-2 millimeters, described elasticity is protected bowl 2 and is positioned at conducting rod body 1 two ends, and be connected with conducting rod body 1 by screw 6, between the another folder of its end and hard sheath 3 and flexible sheath 4, described elasticity is protected another at least uniform 4 osculums 7 on bowl 2, and inwall is not less than 3 centimetres apart from conducting rod body 1 distance, the conductive paste layer 8 of even thickness is separately set between described hard sheath 3 and conducting rod body 1.

During use, first be assembled in order anti-tracking mechanism elasticity being protected to bowl, hard sheath, flexible sheath and cover diaphragm outward, so in conducting rod outside, evenly smear after one deck conductive paste, the anti-tracking mechanism assembling is enclosed within on conducting rod, then with screw, the elasticity at two ends is protected to bowl and be connected with conducting rod; When conducting rod damages or when anti-tracking mechanism damages, only need disassemble the screw that two ends elasticity protects on bowl can be by conducting rod and the replacing of anti-tracking organizational separation.
