A, schneider leakage protector
1. The lower the operating current of the leakage protection device, the better the sensitivity of the switch. However, in any power supply circuit and electrical equipment, the insulation resistance cannot be infinite, and there will always be some leakage current. In order to measure the leakage current of current, it is necessary to use complex test methods or special test equipment. If users use 3A watt-hour meters, the leakage current of each household is about 1ma under normal circumstances. In principle, when the leakage current of a single-phase circuit in the home exceeds 1/3000 of the supply current of the circuit, the circuit should be overhauled.
2. The manufacturer and product information on the packaging of qualified sockets is complete, and some unqualified sockets are poorly packaged, lacking basic manufacturer and product information, that is, the production date on the product packaging. Many inferior sockets are not marked with production date on the packaging, and often belong to unqualified sockets. In addition, the qualified socket shell panel has fine workmanship, the edges of the shell and the jack are burr-free, and the size of the jack is symmetrical and unified, while the poor quality socket shell has rough workmanship.
What brands of leakage protectors are there?
1. brands of leakage protectors-Schneider Schneider Electric (China) Co., Ltd., Schneider Schneider, the top ten brands of electrical equipment and electricians, 1920 started in France, with a glorious history of 170 years, a leading brand in the field of power distribution equipment and a famous manufacturer in the electrical field.
2. Zheng Tai Zhengtai Zhejiang Zheng Tai Electric Appliance Co., Ltd., one of the top ten electrical appliance brands, is the core holding company of listed company Zheng Tai Group, the leading provider of comprehensive solutions for low-voltage electrical appliances in China, and one of the manufacturers of low-voltage electrical appliances with large production and sales volume in China.
3. Delixi Delixi (Delixi Group's LED industry, high-tech enterprise, top 500 Chinese enterprises, famous enterprise in China electrical appliance industry, China Delixi Holding Group Co., Ltd.).
4. It is difficult to define which brand is good, because there are many brand leakage protection switches, and the materials of plastic parts are similar at home and abroad. The key is internal structure and patented technology. There are many foreign patented technologies and old brands. However, the domestic technology is becoming more and more mature and developing, and the cost performance is getting higher and higher. Regardless of the price, Siemens, Simon and other foreign old brands are all good. If the economy is relatively affluent, it can be considered. If the family situation is average, Zhengtai is a leader among domestic brands with high cost performance, and Delixi is also a good domestic brand.
Well, there are articles about the brands of leakage protectors and Schneider leakage protectors. Bian Xiao would like to introduce them here. If you want to buy a good leakage protector, you must know something before you buy it, so that you can buy a good leakage protector.
