Prefabricated substation is constructed mainly through two stages of factory prefabrication and field installation. It will be the conventional substation all electrical equipment, including: main transformer, multiple high voltage in and out switches, reactive compensation devices, insulated bus, substation integrated automation system, communications, remote, metering and DC power supply. In accordance with the principles of systematicness, safety, reliability, easy maintenance and integration, it is installed in a steel box with excellent performance, featuring heat insulation, fire prevention, theft prevention, moistureproof, small animals protection, five sides ventilation, fully enclosed, dismountable, convenient interval increase or decrease, etc.
The construction of prefabricated substation changes the electrical layout, design and construction mode of traditional substation. The former substation "construction" mode is upgraded to "manufacturing" mode through the production of prefabrication and mechanized installation at the construction site, which meets the requirements of "two-type and one-type" substation construction and conforms to the national development strategy. Has the extremely high feasibility, the necessity and the promotion value.
