  • Detail

On january22,2016, the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China notified the national supervision and random inspection of the quality of 34 kinds of products in 2015. Among them, the National Bureau of quality supervision, inspection and quarantine sampled 117 batches of single-phase watt hour meter products from 117 enterprises in 19 heating provinces and cities, and the detection rate of qualified products was 91.5%

according to the report, in the fourth quarter of 2015, 117 batches of single-phase watt hour meter products produced by 117 enterprises in 19 provinces, autonomous regions and municipalities directly under the central government, including Beijing, Hebei, Shanxi, Liaoning, Heilongjiang, Shanghai, Jiangsu, Zhejiang, Anhui, Fujian, Shandong, Henan, Hubei, Hunan, Guangdong, Chongqing, Yunnan, Shaanxi and Ningxia, were spot checked

this spot check is based on gb/t17215 General requirements, tests and test conditions for AC measuring equipment Part 11: measuring equipment, gb/t17 but 215 Special requirements for AC measuring equipment Part 11: electromechanical active energy meters (class 0.5, 1 and 2), gb/t17215 Special requirements for AC measuring equipment Part 21: static watt hour meters (Level 1 and 2) that will be broken into fragments after the expiration of the shelf life, gb/t special requirements for multi rate watt hour meters, gb/t17215 Special requirements for multi function watt hour meters (gb/t18460 IC card prepaid power selling system Part 3: prepaid watt hour meter, dl/t multifunctional watt hour meter and other standards. For single-phase watt hour meter products, kisantwerk is also one of the few manufacturers in China that can produce high-quality U-tubes. This error (inspection items), constant, start, latency, clock accuracy, voltage impact, frequency impact, external magnetic induction intensity impact, power consumption, high-frequency electromagnetic field immunity 16 items such as immunity of electrical fast transient pulse group, immunity of electrostatic discharge, pulse voltage test, AC voltage, alternating damp heat, heat resistance and flame retardance were inspected

according to the spot check, Taiyuan hengyide Electronic Technology Co., Ltd., Taiyuan Woda Electrical Technology Co., Ltd., Harbin today Electronics Co., Ltd., Hangzhou Jingda Electronics Co., Ltd., people's Electric Appliance Group Instrument Co., Ltd., Zhejiang Taifeng Electric Meter Co., Ltd., Shandong Yuejia Electronics Co., Ltd., Guangzhou Phoenix Instrument Co., Ltd., Guangzhou Zhicheng electric measuring instrument Co., Ltd 10 batches of products from 10 enterprises including Weisi electric (Shenzhen) Co., Ltd. do not meet the provisions of the standard, involving high-frequency electromagnetic field immunity, electrical fast but transient pulse group immunity, and alternating damp heat projects
