Description

Transformer outgoing cable bundle with waterproof structure Technical Field The utility model relates to the technical field of transformer cables, in particular to a transformer outgoing cable bundle with a waterproof structure. Background In the power transmission system, a transformer is used as core equipment, and an outgoing cable bundle of the transformer bears the key task of efficiently and stably transmitting electric energy to each power utilization unit, however, the installation environment of the transformer is complex and various, the humid environment is a common and troublesome problem, the outgoing cable bundle is subjected to wind and rain for a long time outdoors, and the outgoing cable bundle is also extremely vulnerable to water vapor in some indoor environments close to a water source or with high humidity. The common cable sheath of traditional transformer is because the structure is complicated relatively, and the sealed degree of difficulty is great, is difficult to play transient barrier effect to steam, is difficult to resist long-term moist erosion, and the moisture in the humid environment combines together with corrosive gas or impurity in the air, can accelerate the ageing process of cable, shortens the life of cable bundle. Disclosure of utility model The utility model aims to provide a transformer outgoing cable bundle with a waterproof structure, which solves the problems that the prior art proposes that the common cable sheath of the traditional transformer is difficult to play a short-term blocking role on water vapor, long-term wet erosion is difficult to resist, and the combination of moisture in a wet environment and corrosive gas or impurities in the air can accelerate the aging process of a cable and shorten the service life of the cable bundle.
