Voltage transformer is an important member of measuring transformer, whose main function is to convert high voltage into low voltage proportionally, providing suitable voltage signals for measuring instruments, relay protection devices, etc. Our voltage transformers use advanced electromagnetic induction principles and are made of high-quality iron cores and insulation materials. They have high conversion accuracy and good stability, and are key equipment to ensure accurate measurement and reliable operation of the power system.
Product Advantages and Features
1. High precision: Using special winding technology and high magnetic permeability iron core, the accuracy level can reach 0.2 level. Within the rated voltage range, the measurement error can be controlled within ± 0.2%, providing strong support for accurate measurement and reliable protection of the power system.
2. Good insulation performance: High performance insulation materials are selected, with an insulation level of up to 110kV, effectively preventing internal discharge and insulation breakdown, ensuring stable operation in high voltage environments, and safeguarding equipment and personnel safety.
3. Wide working range: It can adapt to a working temperature range of -40 ºC to+70 ºC, as well as different humidity environments, and can work stably under various complex natural conditions to ensure the continuous operation of the power system.
4. Strong anti resonance ability: By optimizing design and adopting special damping measures, ferromagnetic resonance is effectively suppressed, avoiding damage to voltage transformers and power system failures caused by resonance, and enhancing system stability.
5. Long life design: Key components have been specially treated to have good wear resistance and corrosion resistance. After more than 5000 opening and closing tests, the average fault free operation time exceeds 80000 hours, reducing maintenance costs.
Application Scenarios
1. Power plant: used to monitor the output voltage of the generator, ensure that the output voltage of the generator is stable within a reasonable range, ensure the normal operation of the power generation equipment, and provide guarantee for reliable power output.
2. Substation: In the substation, precise measurement of bus voltage and line voltage is carried out to provide accurate data basis for power dispatch and distribution, ensuring the safe and stable operation of the power grid.
3. Industrial enterprises: used within factories to monitor and control the power supply voltage of large equipment, promptly detect voltage abnormalities, avoid equipment damage due to overvoltage or undervoltage, and improve production efficiency.
