Abstract

Provided are a power distribution room water logging alarming and automatic draining system and a control method thereof. The system comprises a first water pump motor, a second water pump motor, a first liquid level switch, a second liquid level switch, a third liquid level switch, a liquid level sensor, a motor controller assembly and an uninterrupted power supply (UPS). The control method includes the following steps: 1) arranging the first liquid level switch, the second liquid level switch, the third liquid level switch and the liquid level sensor and then starting a system; 2) utilizing a central processing unit to detect the state of the third liquid level switch first; 3) utilizing the central processing unit to detect the state of the second liquid level switch when the third liquid level switch transmits no signal to the central processing unit; 4) utilizing the central processing unit to detect the state of the first liquid level switch when the second liquid level switch transmits no signal to the central processing unit. The system is high in reliability, good in draining effect, low in energy consumption and good in water pump motor working stability.

Description

technical field [0001] The invention relates to a power distribution system of a power grid, in particular to a water accumulation alarm and automatic drainage system of a power distribution room and a control method thereof. Background technique [0002] The power distribution room is an important part of the power supply system. Monitoring and maintaining the equipment operating environment in the power distribution room is an important part of the management of the power distribution room. There are many electrical equipment and instruments installed in the power distribution room. It is very important to detect and deal with the water accumulation in the power distribution room in time. In rainy weather, power distribution rooms in low-lying areas are prone to flooding and tripping. In severe cases, power distribution equipment will be damaged, resulting in long-term power outages, which have a serious impact on people's lives and production. [0003] At present, there ...
