Abstract

The invention relates to a household electric energy quality monitoring and control device. A shell body is arranged on a monitoring and control unit, a fixed part which is matched with a guide rail inside a PZ 30 distribution box is arranged on a base bottom of the shell body, so that the aim that the fixed part is conveniently arranged inside the PZ 30 distribution box is achieved. The household electric energy quality monitoring and control device is suitable for distribution box standard of existing household users, and users of the PZ 30 distribution box achieve combination of the distribution box and electric monitoring and control equipment just by low cost. Due to the fact that the monitoring and control unit is wholly arranged in the shell body, the shell body plays a role of protecting for the monitoring and control unit, and misoperation or display screen damaging can be effectively prevented.

Description

Technical field [0001] The invention relates to a monitoring device for household electricity, in particular to a household power quality monitoring device suitable for installation in a household PZ30 distribution box. Background technique [0002] With the rapid economic development and the continuous improvement of residents' living standards, various household appliances and digital electronic products have entered the family. Since the quality of power supply and reliability of power supply directly affect electrical equipment, such as voltage fluctuation range, frequency, current abnormality, etc., will directly affect the safety of electrical equipment, so the requirements for power supply quality and reliability of power supply are also increasing. Higher. Once the electrical equipment fails, if it cannot be discovered and dealt with in time, it may cause great economic losses and even endanger personal safety. In order to ensure the quality and reliability of household...
