The invention provides a power distribution cabinet for a transformer station and an integrated transformer station, and relates to the technical field of transformers. The power distribution cabinet is of a double-layer structure, cold air generated by an air conditioner of the power distribution cabinet circulates in an interlayer of a cabinet body of the power distribution cabinet, and vent holes are formed in the surface of a diversion trench; vent holes of different positions and different numbers can be formed according to the installation layout of elements easy to heat, targeted heat dissipation is carried out on the heating elements and the positions easy to heat, meanwhile, the double-layer structure can effectively isolate external temperature, noise generated when an electrical device works can be reduced. The relatively closed structure can effectively isolate external moisture and winged insects, the hexagonal stud can adjust the distance between the clamping block and the heavy base according to the height of a supporting position, and meanwhile, the clamping block and the hexagonal stud are connected in a ball and shaft connection mode, so that when a slope is formed on the mounting bottom surface, the connection mode of ball and shaft connection can adapt to a slope type contact surface, so that the bearing base can be stably placed during installation.
Description
technical field [0001] The invention relates to the technical field of transformers, in particular to a power distribution cabinet for a substation and an integrated substation. Background technique [0002] Rural power grids have the characteristics of large seasonal load fluctuations and low average loads, which are prone to problems such as excessive reactive power of the grid and excessive ratio of transformer no-load loss to transmission capacity. [0003] According to the Chinese patent No. "CN207530412U", a 10KV integrated pole-mounted substation includes a bracket, a transformer and a JP cabinet. The transformer and the JP cabinet are arranged horizontally on the bracket. The JP cabinet is a power distribution cabinet. The outlet end, the high voltage outlet end, and the low voltage outlet end are connected with busbars. The busbars are mainly connected together by multi-section lines. The body of the JP cabinet is equipped with a jack for the busbar to insert, and t...
