Guangzhou will realize full coverage of smart meters and low-voltage remote centralized reading by the end of this year

Abstract: from Scottish watt hour meters and German Siemens watt hour meters made in Britain 100 years ago, to the early domestic "Guangzhou" watt hour meters, and then to the smart watt hour meters with charge control function now... Citizens have a clearer understanding of the development history of Guangzhou watt hour meters during their visits

is the electricity meter at home running fast? "5.20" is the annual World measurement day. Guangzhou Power Supply Bureau of Southern Power Company held the second popular science activity of electric energy measurement knowledge with the theme of lighting the "meter" day, so as to popularize the knowledge of electric meters and measurement for citizens after long-term development

meters should be honed before taking up their posts

on the morning of May 20, Guangzhou Power Supply Bureau of Southern Power Company held the second popular science activity of electric energy measurement with the theme of lighting "meters" in the daytime. Experts from Guangzhou Municipal Bureau of quality supervision were invited to speak for themselves, take citizens into the measurement center of Guangzhou Power Supply Bureau, understand the detection and experimental process of meter measurement, and experience the "transparency, accuracy, fairness and fairness" of meter measurement

from the Scottish watt hour meter made in Britain 100 years ago and the German Siemens watt hour meter, to the early domestic "Guangzhou brand" watt hour meter, to the smart watt hour meter with charge control function now used... Citizens have a clearer understanding of the development history of Guangzhou watt hour meter during the visit

then, following the footsteps of measurement experts, came to the laboratory and watched the destructive test of the meter, including rain test box, high and low temperature alternating test box, sand dust test box, etc. Originally, every electric energy meter needs to be tempered from the manufacturer's production line to the user's meter box. They have to undergo many "production inspections" to ensure that there are no errors in the program. 4. When replacing parts and tools, the measurement is accurate. "Some electric meters need to be installed outdoors, and they face high temperature, exposure to the sun, heavy rain and other weather for a long time. Therefore, a certain proportion of" dead men "in each batch of electric meters have to be selected to accept the tests of water immersion, wrestling, impact, electromagnetic interference and so on." The relevant person in charge said that only by passing the tests at all levels can we complete the task of accurate measurement

"there are many thunderstorms in Guangdong, and sometimes lightning will directly hit the meter itself." In this regard, the relevant person in charge said that they need to test the feasibility of the meter in extreme environments, and at the same time apply electric tension testing machines such as peak overcurrent, lightning impulse voltage and magnetic field to the meter to detect precautions and gas interference sources to test their impact. "But because such experiments do great harm to the meter, only a certain proportion can be randomly selected for detection." After the "punishment", qualified meters will be issued with "certificate of conformity" and officially stationed in the measurement center of Guangzhou Power Supply Bureau

this year, the smart meter will fully cover the promotion and application of the smart meter jg149 ⑵ 003 "expanded polystyrene board thin plastered external wall external insulation system", which realizes the real-time monitoring of the power consumption of each household in the area covered by the system. It has significant advantages such as high measurement accuracy, intelligent fee calculation, automatic meter reading, fault alarm, power memory and balance alarm, When the customer's power consumption is abnormal, it can actively send a signal to the metering automation master station system to facilitate the power supply bureau to deal with it in time. At present, smart meters have been widely used in Beijing and Shanghai

more than 3 million automatic meter reading devices have been installed in Guangzhou, with a coverage rate of 66%. This year, smart meters will be replaced for 1.36 million users and low-voltage remote centralized reading construction will be carried out for 1.5 million users. By the end of this year, Guangzhou Power Supply Bureau will implement full coverage of smart meters and low-voltage remote centralized reading. By then, more than 5.4 million low-voltage users in Guangzhou will all use smart meters and realize remote meter reading. In addition, users who install automatic meter reading devices can monitor the power consumption at home in real time through the automation system of Guangzhou Power Supply Bureau
