Problems solved by technology
[0002] At present, substations are usually installed on the ground, carrying the functions of transforming voltage, receiving and distributing electric energy, controlling the flow of electric power and adjusting voltage in the power system. However, the way of outdoor installation needs to occupy the surface space, which affects the development of urban planning and also hinders the environment. beautiful
[0003] In addition, most of the current transformers have not been able to solve the sealing problem between themselves and the outside world, and cannot meet the requirements of waterproof and moisture-proof. The stability of power supply in harsh environments is poor, and they cannot resist floods, and are easily affected by the external environment. As a result, the internal components are aging and damaged, and the transformer needs to be inspected and maintained regularly

The invention discloses an all-insulated buried transformer. The all-insulated embedded transformer comprises a box with a built-in transformation component, and a metal shell I and a metal shell II are arranged on the outer wall of the box; a primary terminal connecting the transformation component with an inlet wire cable is arranged in the metal shell I, and a secondary terminal connecting the transformation component with an outlet wire cable is arranged in the metal shell II; insulating waterproof materials are poured in the metal shell I and the metal shell II, and the box, the metal shell I and the metal shell II are of an integrated seal welding structure. According to the all-insulated buried transformer, by means of the integrated seal welding structure of the transformer, the stability and safety of the transformer are guaranteed, maintenance-free of the transformer is achieved, the excellent waterproofness is achieved, normal working is still guaranteed even if the transformer is immersed in flood, a buried installation mode can be adopted, the earth surface space is not occupied, and the environment is attractive; original bolt fixing assembly work is avoided, and the labor intensity is reduced.
