Description: Intermediate frequency furnace voltage transformer sampling transformer 3000V2500V1500V1000V to 100V20V The working principle of the voltage transformer The working principle of the voltage transformer is the same as that of the general transformer. 1. Voltage transformer: A voltage transformer is a voltage conversion device. It converts high voltage to low voltage so that the change of high voltage magnitude can be reflected with low voltage magnitude. Therefore, voltage measurement can be performed directly with ordinary electrical instruments through the voltage transformer. 1. The voltage transformer, also known as the instrument transformer, is a voltage conversion device; 2. The capacity of the voltage transformer is very small, usually only tens to hundreds of volts; 3. The voltage on the primary side 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 load is mainly the instrument and the relay coil, which have a large impedance and pass very little current. If the secondary load is increased indefinitely, the secondary voltage will decrease, resulting in an increase in measurement errors; 5. Use a voltage transformer to indirectly measure the voltage, which can accurately reflect the value of the high-voltage side and ensure the measurement accuracy; 6. Regardless of the voltage mutual inductance No matter how high the primary voltage of the relay is, its secondary rated voltage is generally 100V, which makes the manufacturing of measuring instruments and relay voltage coils standardized. It also ensures the safety of instrument measurement and relay protection work, and also solves the difficulties of high-voltage measurement insulation and manufacturing process; 7. Voltage transformers are often used in power distribution instrument measurement and relay protection circuits. 1. Packing: 1PCS 2. Warranty period: 120 days
