single phase potential transformer voltage transforemer

Overview: Indoor dry type voltage transformer is an electrical device used in indoor environments to measure and monitor the voltage of circuits. Compared with traditional oil immersed transformers, dry type transformers adopt an oil-free insulation structure, which does not require maintenance and upkeep, making them safer and more reliable. Dry type voltage transformers typically use epoxy resin insulation material to protect the windings and insulation system, ensuring high electrical performance and weather resistance. They have smaller volume and weight, making them more convenient to install in indoor circuits and suitable for various occasions such as homes, commercial, and industrial buildings. The working principle of a dry type voltage transformer is to convert high voltage signals into lower measurable voltages for connection to electricity meters, measuring instruments, or monitoring equipment. These transformers usually have high accuracy and sensitivity, and can stably and accurately measure the voltage of the circuit. Dry type voltage transformers have high insulation strength and withstand voltage capability, which can maintain stable and reliable performance in different working environments. In addition, they also have low loss and noise characteristics, which can provide high-quality voltage measurement results. Overall, indoor dry type voltage transformers are safe, reliable, and easy to install and maintain electrical equipment, widely used in various power systems and circuits to ensure the safe operation of circuits and high-precision voltage measurement. Product Structural features : 1. High insulation strength: The epoxy resin used for casting has an insulation breakdown field strength of 18-22kV/mm, and has approximately the same lightning impulse strength as oil immersion transformers with the same voltage level. 2. Strong short-circuit resistance: Due to the material characteristics of the resin and the overall casting of the winding, it becomes a rigid body after heating and solidification, resulting in high mechanical strength. Through sudden short-circuit tests, it has been proven that cast type transformers are rarely damaged due to short circuits. 3. Outstanding disaster prevention performance: Epoxy resin is flame retardant, flame retardant, and can self extinguish without causing secondary disasters such as explosions. 4. Excellent environmental performance: Epoxy resin is an extremely stable material in chemistry, moisture-proof and dustproof. It can operate reliably even in harsh environments such as atmospheric pollution, and can even operate normally at 100% humidity. After shutdown, it can be put into operation again without the need for drying and preheating. Being able to operate under harsh environmental conditions is one of the outstanding advantages of epoxy casting dry transformation compared to immersion dry transformation. 5. Minimal maintenance workload: With a comprehensive temperature control and display system, the daily maintenance workload of epoxy casting dry transformer is currently very small, which can greatly reduce the burden on operating personnel and reduce operating costs. 6. Low operating losses and high operating efficiency 7. Low noise. 8. Small size, light weight, and convenient installation and debugging. 9. There is no need for a separate transformer room or hanging core maintenance, saving land area and corresponding civil engineering investment.
