Abstract
The utility model discloses a transformer high-voltage bushing with the waterproof function. The transformer high-voltage bushing is mainly composed of a metal sheath (1) and a rubber washer (2). A transformer lead connecting rod (6) is sleeved with the metal sheath (1). The rubber washer (2) is located between the metal sheath (1) and the lead connecting rod. The lower portion of the metal sheath (1) is fixedly connected with a transformer through a bolt (3). According to the transformer high-voltage bushing, the metal sheath is arranged outside a transformer lead in a sleeved mode, the rubber washer is arranged for sealing the metal sheath and the lead, and water is prevented from entering the bushing. In order to further ensure the sealing performance of the bushing, a fastening ring is arranged outside the metal sheath, the metal sheath is fixed to the lead through the fastening ring, and water is prevented from flowing into the bushing along the lead; in order to prevent water from entering the transformer through an oil injection plug, a waterproof cover is particularly arranged, and therefore water is prevented from entering the transformer through the oil injection plug; due to the fact that an air sealing ring and a sealing washer are arranged, water is prevented from being leaked into the transformer from the bottom of the metal sheath, and the sealing performance of the bushing is improved.
Description
Technical field
The utility model relates to field of electrical equipment, specifically refers to a kind of transformer high-voltage bushing with water-proof function.
Background technology
Bushing is the vitals of transformer, the effect of bushing shell for transformer is that inner transformer high and low pressure is guided to fuel tank outside, not only as lead-in wire insulation against ground, and the effect of undertaking anchor leg, bushing shell for transformer is one of transformer current-carrying element, sleeve pipe transformer sleeve pipe end is poorly sealed just easily there is the phenomenon of leaking to the inside along lead-in wire connecting rod, leak or infiltration situation under, transformer coil easily burns out.Traditional transformer high-voltage bushing sealing is poor, and traditional cannula tip is directly connected with terminal block, make sleeve pipe there is the double action of sealing and conduction simultaneously, in use, there is a lot of hidden danger, moisture enters transformer inside along lead-in wire connecting rod, and near lead-in wire, winding burns out and just probably causes breakdown accident.
Utility model content
The purpose of this utility model is to provide a kind of transformer high-voltage bushing with water-proof function, can effectively avoid water to enter transformer along lead-in wire and cause transformer coil scaling loss, thereby the security incident of avoiding ensures Electrical Safety by optimal design.
The utility model is achieved through the following technical solutions: a kind of transformer high-voltage bushing with water-proof function, mainly formed by metallic sheath, rubber washer, described metallic sheath is sleeved on transformer lead connecting rod outside, described rubber washer is between metallic sheath and lead-in wire connecting rod, and described metallic sheath bottom fixes by bolt and transformer.
Further, for realizing better the utility model, be set with the tight loop of openings at one side in described metallic sheath upper outer wall, described tight loop opening one side is fixed by fastening bolt.
Further, for realizing better the utility model, be also provided with sealing gland circle in described metallic sheath lower inside.
Further, for realizing better the utility model, be provided with holder at described metallic sheath near transformer pouring plug cock one side, holder top is connected with bucker by pin, on transformer, be also provided with projection, described bucker is positioned at projection top away from holder one end.
Further, for realizing better the utility model, between described bolt and metallic sheath, be provided with seal washer.
The utility model compared with prior art, has following beneficial effect:
(1) the utility model is set with metallic sheath in transformer lead outside, and by rubber washer is set, metallic sheath and lead-in wire is sealed, and anti-sealing enters inside pipe casing downwards along lead-in wire connecting rod;
(2) the utility model, in order further to ensure the sealing of sleeve pipe, at metallic sheath arranged outside tight loop, is further fixed to metallic sheath lead-in wire by tight loop upper, avoids water to flow into sleeve pipe along lead-in wire;
(3) the utility model, for anti-sealing enters transformer by oil filler plug, is provided with waterproof cover on oil filler plug top especially, thereby avoids water to enter transformer by oil filler plug;
(4) the utility model is by metallic sheath bottom, sealing gland circle being set, and at bolt and metallic sheath junction, seal washer is set, and anti-sealing infiltrates transformer from metallic sheath bottom, thus the sealing property of raising sleeve pipe.
