Description

technical field [0001] The invention relates to a power monitoring device, in particular to a power quality monitoring device for industrial and mining enterprises. Background technique [0002] In industrial and mining enterprises, the production quality of products often depends on the power quality output by distribution transformers. For example, when the power supply voltage and frequency are unstable in the spinning mill, the yarn produced will be uneven in thickness. Due to the power quality problem of the electric heating equipment, the heated parts will not meet the heating requirements, and energy and raw materials will be wasted. The power output of the existing distribution transformers is mostly equipped with a watt-hour meter to record the power consumption, but it cannot monitor the power quality. With the popularization of smart watt-hour meters, the power quality output by the distribution transformer can However, smart watt-hour meters are mostly installed...

Problems solved by technology

For example, when the power supply voltage and frequency are unstable in the spinning mill, the yarn produced will be uneven in thickness. Due to the power quality problem of the electric heating equipment, the heated parts will not meet the heating requirements, and energy and raw materials will be wasted.

The power output of existing distribution transformers is mostly equipped with a watt-hour meter to record the power consumption, but it cannot monitor the power quality. With the popularization of smart watt-hour meters, the power quality output by the distribution transformer can It is monitored, but the smart watt-hour meter is mostly installed with the distribution transformer, which is not convenient for people to know the power quality output by the distribution transformer in real time; it cannot be adjusted according to the power quality to ensure the quality of the produced products
