Induction melting furnace spare parts:MF voltage transformer

The working principle of a voltage transformer is the same as that of a general transformer, except that it differs in structure, material, capacity, error range, etc.

1. Voltage transformer: A voltage transformer is a voltage conversion device. It converts high voltage to low voltage so that the low voltage value reflects the change of the high voltage value. Therefore, it is possible to directly measure voltage with ordinary electrical instruments through the voltage transformer. 1. Voltage transformer, also known as instrument transformer, is a kind of voltage conversion device;
2. The capacity of voltage transformer is very small, usually only tens to hundreds of volt-amperes;
3. The primary voltage of the voltage transformer is the grid voltage, It is not affected by the secondary load, and its load is constant in most cases;
4. The secondary side load is mainly meters and relay coils, their impedance is very large, and the current passing through is very small. If the secondary load is increased indefinitely, the secondary voltage will decrease, causing measurement errors to increase;
5. Use a voltage transformer to measure voltage indirectly, which can accurately reflect the value of the high voltage side and ensure measurement accuracy;
6. Regardless of voltage mutual inductance How high the primary voltage of the device is, and its secondary rated voltage is generally 100V, so that the manufacturing of measuring instruments and relay voltage coils can be standardized. Moreover, it ensures the safety of instrument measurement and relay protection work, and also solves the difficulties of insulation and manufacturing process for high-voltage measurement;

7. Voltage transformers are often used in circuits such as transformer and distribution instrument measurement and relay protection.
