Description

technical field [0001] The invention belongs to the technical field of electrical control, and in particular relates to an electrical control system of a rainwater pump in a rainwater pumping station. Background technique [0002] Rainwater pumping station undertakes the important task of flood drainage and waterlogging prevention. If it cannot be put into operation in a timely and reliable manner when the heavy rain falls, it will cause urban water accumulation in a short period of time, causing major economic losses, and even threatening the safety of people's lives and property. Due to the large instantaneous flow of rainwater in big cities, the role of large-scale rainwater pumping stations is becoming more and more important. High-power rainwater pumps are usually driven by high-voltage motors. According to the power supply voltage level, most high-voltage motors on the market use 3kV And above high voltage power supply. Due to the increasing scale of construction, the...
