With the development of the solar energy industry, solar photovoltaic power plants with large installedl capacity are also developing rapidly. People are interested in equipmentThe performance of control and protection appliances in large solar photovoltaic power plants has also put forward higher and higheri requirements. When a photovoltaic power plantWhen the power exceeds a certain level, a circuit breaker orl isolating switch is required, especially for the protection and isolation of the inverter Components pose new requirements. To this end, our company has developed a new generation of photovoltaic dedicated Dc circuit breakers based on the original photovoltaic DC circuit breakersCurrent circuit breaker.
Photovoltaic dedicated DC circuit breakers (hereinafter referred to as circuit breakers) are used in DC powerl grid circuits with a rated voltage of DC250VD-C1000VD and a rated workflow of 63A-630A. This circuit breaker has an overload long delay short circuit instantaneous protection function to distribute electrical energy and protect lines and power supplies from overload, short circuit, and other fault hazards
This circuit breaker meets the following standards:
