Multifunctional control cabinet for rainwater pumping station

Abstract

The invention belongs to the technical field of water pump control, and particularly relates to a multifunctional control cabinet of a high-power water pump high-voltage motor in a rainwater pumping station. According to the multifunctional control cabinet for the rainwater pumping station, a multifunctional control cabinet panel is provided with a PLC display screen, a first tour-inspection instrument and a second tour-inspection instrument, and the PLC display screen is connected with the first tour-inspection instrument and the second tour-inspection instrument respectively. The first tour-inspection instrument is connected with a comprehensive fault signal lamp, a rainwater pump temperature alarm signal lamp, a water outlet valve switch signal lamp, a water inlet channel low-liquid-level alarm signal lamp, an outflow water pressure alarm signal lamp and the like which are arranged on the multifunctional control cabinet panel through a signal collection cable; the second tour-inspection instrument is connected with a rainwater pump temperature sensor, a water inlet tank liquid level meter and an outflow water channel liquid level meter respectively. The multifunctional control cabinet provides a reliable guarantee for running of a rainwater pump with a high-voltage power supply of 3 kV or above in the rainwater pumping station, and comprehensive control of the high-voltage motor of 3 kV or above can be completed; the working states of all on-site electrical devices are displayed, and normal running of the rainwater pump is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of water pump control, and in particular relates to a multifunctional control cabinet for a high-voltage motor of a high-power water 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 simple, reliable and timely manner when the heavy rain falls, it will cause urban water accumulation in a short time, cause major economic losses, and even threaten 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 increas...
