Silicon molybdenum rod glass electric melting furnace transformer equipment
The silicon-molybdenum rod (glass electric melting) furnace transformer is designed by our company for the silicon-molybdenum rod electric furnace (glass electric melting furnace).
The silicon-molybdenum rod (glass electrofusion) furnace transformer is used for the power supply of the silicon-molybdenum rod (glass electrofusion) furnace.
3. Structural characteristics
The resistance of the silicon molybdenum rod electric heating body increases sharply with the temperature increase. When the heating is started, the electric heating body has a small resistance and the required voltage is low, which is about l / 4 — 1 of the working voltage / 3, according to the working voltage of the silicon molybdenum rod electric heating body and the positive characteristics of its resistance and temperature, the output voltage of the transformer uses a multi-tap method to meet the working voltage required by the heating body at different temperatures, thereby improving the power grid Power factor.
The insulation of the transformer is divided into two categories: inner insulation and outer insulation, and the inner insulation is divided into two types of main insulation and longitudinal insulation. There are three kinds of voltages that transformers withstand during operation: long-term working voltage, internal overvoltage, and external overvoltage. The insulation effect of these three voltages on the transformer should be checked with the test voltage, but there are too many internal overvoltage varieties, and it cannot be checked one by one on the transformer. The overvoltage multiple of the operating overvoltage is high, so only the operating overvoltage is used to replace the internal overvoltage.
