The high and low voltage switchgear in the outdoor dedicated box substation of photovoltaic wind power station (also known as pre-installed substation or box transformer) is an indispensable part of the power system. The main function is to control, protect and distribute electricity to ensure the safe and efficient operation of photovoltaic wind power stations.
Product/performance characteristics
The role of high and low voltage switchgear in photovoltaic wind power stations:
Control function: The high and low voltage switchgear can control the electrical connection between different devices in the photovoltaic power generation system to achieve reasonable distribution and transmission of electric energy. In a wind power generation system, the high and low voltage cabinet can control and manage the electrical energy generated by the fan and deliver it to the power generation system.
Protection function: High and low voltage switchgear can protect the electrical equipment in the photovoltaic power generation system, such as inverters, transformers, AC cables and other equipment. These devices may be affected by various factors during operation, such as overcurrent, overvoltage, short circuit, etc. High and low voltage switchgear can cut off the fault circuit in time to protect the equipment from damage.
Distribution function: high and low voltage switchgear can distribute the power in the system. In the photovoltaic power generation system, the low-voltage switchgear is mainly used for the power system with a voltage of 380V and below, the medium-voltage switchgear is used for the system with a voltage in the range of 1kV to 35kV, and the high-voltage switchgear is used for the system with more than 35kV. According to the needs of the system, the power is distributed to various inverters, transformers and other equipment to meet the needs of users.
