Electric energy monitoring method

Abstract

The invention relates to an electric energy monitoring method. The method is as below: an area voltage sampling module is responsible for sampling voltages between a transformer and an ammeter; an ammeter voltage sampling module and an ammeter current sampling module are responsible for sampling voltages and currents between the ammeter and an indoor air switch; an indoor air switch voltage sampling module is responsible for sampling indoor wiring voltages; a processing module processes various data, operates through a button module, and controls a display module to perform information interaction with a server through a wireless transmission module; a data storage module stores data; and the server performs comprehensive processing on monitoring data, and performs data interaction with acentralized monitoring system and a mobile client. The method can timely reflect which section of "area-ammeter-indoor air switch" has a problem, and assist a power supply company to make different types of treatment decisions while monitoring the quality of electric energy in the area according to acquired data.

Description

technical field [0001] The invention relates to a method for monitoring electric energy, in particular to a method for monitoring low-voltage electric energy. Background technique [0002] Now power users are becoming more and more aware of rights protection, and even excessive rights protection. In recent years, as long as there is a power outage in many power users' homes, no matter what the reason is (the lines behind the household meter belong to the user's property and are not within the scope of the power company's handling responsibility), they will first complain to the power company, which will almost saturate the carrying capacity of the original work order. The staff of the power supply company brought a lot of pressure. The existing system of the power supply company cannot carry out the analysis of power outages to households in time, and there is a certain time delay. At this time, during this time period, some users complained, and the power supply company g...

Problems solved by technology

This phenomenon has caused a great waste of emergency repair resources for the power supply company

[0003] Due to lack of professional electricians in some temporary sites such as construction sites, small factories, small workshops, etc., when encountering a power outage, they do not know the problem and deal with it randomly, resulting in unsafe use of electricity and delaying production.

Due to the poor power conditions of the above users, the power quality may not be able to meet the power supply requirements of some instruments

Existing low-voltage household meters do not have the function of real-time online monitoring of power quality, and power quality testing instruments are mainly fixed at certain important nodes that require power quality monitoring, but cannot fully cover them, and are expensive, and temporary power consumption sites such as construction sites are also expensive. Difficult to assess their own power quality, let alone how to improve power quality

[0004] At present, there is no electric energy monitoring device on the market that can promptly respond to problems in which section of "the station area - electric meter - household air switch"
