Intelligent media landscape-type buried energy-saving box transformer substation

Abstract

The invention discloses an intelligent media landscape-type buried energy-saving box transformer substation comprising a lamp box-type power distribution cabinet arranged on the ground and an underground transformer arranged inside an underground prefabricated pit. A transformer core is arranged inside the underground transformer. The lamp box-type power distribution cabinet and the underground transformer are connected via a high-voltage cable and a low-voltage cable. The lamp box-type power distribution cabinet is internally equipped with a fully-sealed self-locking separable connector. The surface of the underground transformer is equipped with an inner cone-type cable connector. The high-voltage cable and the low-voltage cable are connected into the lamp box-type power distribution cabinet via the fully-sealed self-locking separable connector, and the high-voltage cable and the low-voltage cable are connected to the underground transformer via the inner cone-type cable connector. The box transformer substation has effective dustproof, moisture-proof, waterproof and anti-mechanical external force functions, and can be effectively prevented from being accidentally damaged by small animals. The anti-corrosion and sealing capabilities of the underground transformer are ensured. The underground transformer can be immersed in water for a period of time. The entire level of protection is high.

Problems solved by technology

[0007] At present, the widely used buried transformers mostly use oil-immersed transformers, and the shell of the oil-immersed transformers is used to achieve the purpose of anti-leakage and waterproof. However, there are the following types of problems in actual operation: the high voltage of many buried transformers The connection method adopts the detachable connector (plug head) used in the ordinary European or American outdoor cable branch box to connect, and the sealing is not enough; the box body of most buried transformers has not been treated with special acid Long-term operation in an underground humid environment will corrode the box shell, which will lead to potential safety hazards in power operation; many buried transformers themselves do not have the function of underground operation, and can only rely on the foundation, foundation, and pit cover to be fully sealed. Waterproof and moisture-proof. Once the cover plate is damaged, water or moisture intrusion will cause hidden dangers in power operation; the operation of many buried transformers depends on the foundation, foundation, and built-in suction pumps in the corners of pits to drain water. If the situation is poured into the underground foundation, the excretion function will be lost, which will lead to potential safety hazards in the operation of the transformer; the high-voltage connection method of many buried transformers adopts the traditional silicone rubber soft connection method to be exposed in the pit, which cannot effectively prevent small animals and external mechanical forces damage, thereby increasing the safety hazard of power operation

However, as the requirements for the urban environment and image are getting higher and higher, the problems exposed by the traditional box-type substation as one of the urban infrastructures in the operation of some areas are becoming more and more obvious: it takes up a lot of space and crowds out the bustling areas. Narrow space; equipment above the ground is easy to be stolen and damaged; it is easy to become a small advertising carrier and a visual "pollution source" affecting the urban environment

Therefore, in urban construction, traditional box-type substations can no longer meet the needs of social development and urban environment construction, which urgently needs a new type of street lamp power distribution equipment
