Abstract
The invention discloses a cable sealing device for a buried transformer. The sealing device comprises a lead box, a limiting sleeve, a pressure screw and a sealing ring, wherein the lead box is arranged on the outer side of a transformer three-phase cable connecting seat; the lead box is provided with a transformer three-phase cable input hole; a transformer three-phase cable is connected to the transformer three-phase cable connecting seat in the lead box through the limiting sleeve; the limiting sleeve is arranged in the transformer three-phase cable input hole; the sealing ring is arranged between the limiting sleeve and the transformer three-phase cable; a silicone rubber particle layer is filled in the sealing ring; and the pressure screw for fixing the sealing ring and the transformer three-phase cable is arranged on the limiting sleeve. The sealing device has good sealing effect, prevents leakage at the sealing position of the three-phase cable and ensures safe and reliable running of the buried transformer.
Description
Technical field
The invention belongs to buried transformer and supply the distribution field, is a kind of waterproof assembling that is used for buried transformer turnover cable, specifically a kind of buried transformer cable sealing device.
Background technology
Along with urban land resource anxiety and land price constantly rise suddenly and sharply, some supplies distribution system employing that transformer is embedded under the melt pit and supplies distribution.This confession distribution system has been practiced thrift cost of investment undoubtedly, does not also influence the city appearance of the city simultaneously, thereby receives owner's welcome in the big city.But transformer moves in melt pit, and sixty-four dollar question is to want waterproof.Buried transformer turnover lead-in wire all is a threephase cable, and existing waterproof measure generally is perforate on the transformer outlet box, on threephase cable, overlaps sealing ring, compresses sealing then.Because cable is made up of three strands of single-phase cables, thereby the outer adapter ring of cable is very irregular, there is the seepage situation to take place after the sealing unavoidably, also can only deal with problems in short-term even if stamp glass cement, operation has brought potential safety hazard to transformer.
Summary of the invention
In order to overcome the problem that prior art exists, the purpose of this invention is to provide a kind of buried transformer cable sealing device, sealing device good sealing effect can not produce seepage in the threephase cable seals at, has guaranteed the safe and reliable operation of buried transformer.
The objective of the invention is to realize through following technical scheme:
A kind of buried transformer cable sealing device; It is characterized in that: the sealing device comprises pull box, stop collar, pressure screw and sealing ring; Pull box is arranged on the outside of transformer threephase cable Connection Block, on pull box, is provided with transformer threephase cable input hole; The transformer threephase cable is connected on the transformer threephase cable Connection Block in the pull box through stop collar; Stop collar is arranged on transformer threephase cable input hole place; Sealing ring is arranged between stop collar and the transformer threephase cable, in sealing ring, is filled with the silicone rubber particles layer; The pressure screw that is used for fixing sealing ring and transformer threephase cable position is arranged on the stop collar.
Sealing ring according to the invention is two-layer, and the internal diameter of sealing ring and transformer threephase cable are suitable; The external diameter of sealing ring and the internal diameter of stop collar are suitable; The silicone rubber particles layer is filled between the two-layer sealing ring.The diameter of silicone rubber particles layer can be for about 1mm.
The present invention is a kind of new threephase cable sealing device, and the elasticity through the short grained silicon rubber in the sealing ring is sealed irregular threephase cable fully.After this device used, none seepage of threephase cable seals at had guaranteed the safe and reliable operation of buried transformer.
