Compact substation
Photovoltaic power generation box type transformer (Chinese style)
Product Introduction
YB20G- port/port-port series special box type transformer for photovoltaic power generation (Chinese style) is a high/low voltage prefabricated substation integrating high voltage switchgear, oil-immersed step-up transformer, low voltage switchgear and corresponding auxiliary equipment. It is a special power distribution facility that the low voltage from the photovoltaic grid-connected inverter through the battery module is raised to 35kV through the oil-immersed step-up transformer, and then the power is output upwards through the 35kV line, and it is an ideal supporting equipment for the photovoltaic power generation system.
Product Model
Product Features
Adopt integrated top cover, with high protection level, compact structure and small floor space.
The high voltage is equipped with an independent high voltage cabinet, and the load switch fuse combination electric appliance or vacuum circuit breaker is used, so that the safety protection is guaranteed and the maintenance is convenient.The oil-immersed transformer is used, the oil is used as the insulation material, and the radiator is external, so that the heat dissipation effect is good. The transformer oil tank is equipped with a pressure gauge with a communication interface, and the low oil level signal, high temperature alarm signal and overtemperature trip signal are networked with the main station through a microcomputer device, so that telemetry, remote control and real-time monitoring of the substation can be realized.
The protection level is IP54, which is suitable for harsh environments such as strong sandstorm and extreme temperature.
It is convenient for repair and maintenance, and reduces the operation cost.
