2018-07-18 Why is the output terminal of UPS connected with isolation transformer The output terminal of UPS is connected with isolation transformer, which can produce isolation grounding point and voltage transformation. The advantages of isolation transformer applied in ups are as follows: 1. It can reduce the zero to ground voltage and optimize the ups terminal power supply network. The isolation transformer installed in the inverter output of UPS can isolate the electrical connection between input and output, thus effectively reducing the zero to ground voltage at the output end. 2. It can filter out -
2018-07-18 Principle and function of transformer The transformer is an important device to convert electric current and voltage into another kind of electrical equipment. It can be wound according to the principle of different applications -
2018-07-18 Pressurizer function With the rapid development of China's economic construction, the social demand for power resources is growing, and the demand for power system is also higher and higher. While meeting the demand and growth of power consumption, maintaining the stability and reliability of power supply has become an important issue for the power industry. The electrical components in our life are almost everywhere, such as the large-scale lighting of shops and buildings, the household appliances in the family, the office in the office, etc -
2018-07-18 Introduction of high power voltage regulator Overview (dbw.sbw single and three-phase fully automatic compensated power regulators SBW, DBW series single and three-phase full-automatic compensation power regulators are voltage regulators introduced and absorbed by our company from Western Europe, and designed to stabilize AC voltage according to China's national conditions. When the external power supply network voltage fluctuation or load change causes voltage fluctuation, the voltage regulator (regulated power supply) can automatically maintain the output voltage of -
2018-07-18 Overview of three phase dry type transformer Three phase transformer product description three phase transformer is a new generation of energy-saving power transformer developed and produced by our factory on the basis of international similar products and China's national conditions. It conforms to international and national standards such as iec439 and gb5226. The winding adopts the method of whole train winding without tire. The transformer is vacuum impregnated to make the insulation grade of transformer reach grade F and the product performance reaches the first at home and abroad Go to the level. Three phase transformer is widely used in AC -
2018-07-18 Applicable range of transformer Lighting transformer is suitable for 50-60Hz AC circuit. It is widely used in electronic industry or industrial and mining enterprises, machine tools and mechanical equipment in general circuit control power supply, safety lighting and indicator light power supply. Transformer -- technical specifications the primary winding is wound separately. When the secondary winding has only one winding, it bears all the rated capacity of the transformer. Secondary, such as control, lighting and indicator lights
