Title:
NATURAL VENTILATION HIGH PROTECTION LEVEL MODULAR PREFABRICATED TRANSFORMER STATION
Document Type and Number:
WIPO Patent Application WO/2020/258759
Kind Code:
A1
Abstract:
A natural ventilation high protection level modular prefabricated transformer station, comprising a box body, a closed box chamber and a transformer chamber (3) with an open structure being arranged in the box body, the closed box chamber and the transformer chamber (3) being isolated from one another, the closed box chamber being divided by means of a partition plate into a high voltage chamber (6) with a high protection level and a low voltage chamber (13) with a high protection level, a high voltage switch device being arranged in the high voltage chamber (6), and a low voltage switch device and a remote control box (8) being arranged in the low voltage chamber (13), a power distribution terminal being arranged in the remote control box (8), a transformer (4) being arranged in the transformer chamber (3), and the transformer (4) being connected to a low voltage circuit breaker in the low voltage switch device via a low voltage bus bar (12); the problems of the low protection level of the housing of box-type transformer stations and the poor heat dissipation of the transformer chamber (3) are thereby solved, such that the capacity of the transformer (4) is fully utilised, increasing the rate of utilisation of the transformer (4) and expanding the scope of application of box-type transformer stations.
