Abstract
The utility model discloses a distribution system for a middle voltage ring network combined type transformer station. With the development of the urbanization, low voltage can no longer satisfy the basic needs of the urban residents, so that the medium voltage of 20KV-40KV is more and more applied in the urban power grid. However, because the voltage is too high, people could die by accidentally touching the medium voltage looped network cabinet; and the looped network cabinet could leak electricity by contacting with water when rainy days comes. A distribution system for a medium voltage looped network combined type transformer station comprises a looped network cabinet possessing a housing (1) which is connected to a moistureproof socket seat (2); the moistureproof socket seat (2) is connected to a protective rail which is telescopic; and the controllable rail is connected to an insulation material layer (11). The distribution system for the medium voltage looped network combined type transformer station is applicable to the medium voltage lopped network combined type transformer station.
