The invention discloses an energy-saving high-voltage frequency converter cooling system which comprises a water supply system, a filter, a high-voltage frequency converter chamber, a cooling tower water supplementing pool and a water storage tank. A plurality of high-voltage frequency converters are arranged in the high-voltage frequency converter chamber, and a surface air cooler is arranged onthe outer side of the high-voltage frequency converter chamber. Exhaust fans are arranged in the tops of the high-voltage frequency converters, exhaust outlets are formed in the tops of the high-voltage frequency converters and connected with an air inlet section of the surface air cooler through a hot air pipe, and a cold air pipe extending into the high-voltage frequency converter chamber is connected to an air outlet section of the surface air cooler. The water supply system is connected with a water inlet pipe of the surface air cooler through a water supply pipeline, and a filter is arranged on the pipeline between the water supply system and the surface air cooler. A water outlet pipe of the surface air cooler is connected with the cooling tower water supplementing pool through a water outlet main pipe, and the water storage tank is connected with the water outlet main pipe through a water storage branch pipe. The transformation cost is low, and the power consumption cost of an enterprise can be saved.
Description
technical field [0001] The invention relates to the technical field of high-voltage frequency converters, in particular to an energy-saving high-voltage frequency converter cooling system. Background technique [0002] In recent years, with the development of power technology and the improvement of frequency conversion speed regulation technology, some new high-voltage frequency converters have been developed with excellent performance, which can realize PWM inverter and even PWM rectification, which have replaced the adjustment methods of baffles and valves. . Its stable and safe operation performance, simple and convenient operation mode, and perfect functions will make the frequency conversion finally achieve the purpose of high-efficiency operation. With the continuous maturity of high-voltage frequency conversion technology, high-voltage frequency converters have been widely used in various fields. [0003] In order to ensure the normal operation of the equipment in t...
