A transformer is a kind of electrical equipment that stops; as its name implies, a transformer is used to transform voltage, and it is one of the main equipment in power plants and substations. The function of the transformer is multi-faceted, which can not only increase the voltage and send the electric energy to the power-consuming area, but also reduce the voltage to the operating voltage at all levels to meet the demand for electricity. In short, both step-up and step-down must be completed by the transformer. In the process of transmitting electrical energy in the power system, two losses of voltage and power will inevitably occur. When the same power is transported, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage. Using a transformer to increase the voltage reduces transmission losses. Therefore, the transformer plays a very important role in the whole process of electric energy production, transmission and distribution.
Imported machine tools generally use transformers. The development of machine tool transformers in China has experienced more than 10 years of development. Now the technology has matured, and after many years, it has further absorbed similar foreign products.
Imported machine tools use different voltages and frequencies due to different countries of import. Domestic industrial electricity is 380V, 50Hz AC, foreign countries have 440V and 110V, and the frequency is 50Hz and 60Hz. Importing countries use transformers to transform into different voltages and frequencies.
Take the JBK6 machine tool control transformer series as an example:
JBK6 series machine tool control transformers are imported from Germany in the mid-1990s, the latest Satons transformer series, and the foreign advanced terminal structure is selected, the terminal and the skeleton are combined together, the vacuum dipping process is adopted, and the insulating material is imported from abroad. The insulation performance is more stable , concise and clear, especially the one-time molding of the bottom plate, the installation size is more accurate, and the use of high-quality anti-corrosion alloy materials, with short-circuit and thermal protection devices, greatly improves the reliability of grounding performance, and comprehensively improves product quality.
