Combined current and voltage transformers: Combined transformer combination of current and voltage transformers made more attached to the high-pressure metering box, cabinet, or for use as electrical energy metering device power protection devices. Combined current and voltage transformers are the two or three current transformer primary and secondary windings and iron core and a voltage transformer secondary winding and high voltage transformer core Dalian Which is better? Fixed on the high voltage transformer steel body frame, fitted with transformer oil immersion cabinets, one of the secondary windings are drawn Harbin high voltage transformer outlet Which is better? , Then in the box outside the high, the low-voltage insulator, forming an insulating closed whole. One side and the supply line is connected, the secondary protection devices and metering device or connection. Depending on the needs of current and voltage transformer combined into V / V wiring and Y / Y junction of two to three-phase energy metering when load balanced or unbalanced. The basic structure of the voltage transformer and the transformer is very similar, it also has two windings, a high voltage transformer called a winding Jilin Which is better? One called the secondary winding. Two windings are housed in or around the core. Between the two windings and the core and windings have insulation that has electrical isolation between the two windings and winding and core. Voltage transformer At run time, the primary winding N1 and the line coupling, and coupled to the secondary winding N2 meter or relay. Therefore, when measuring the voltage of the high voltage on the road, despite a high voltage, but the second is a low pressure, you can ensure the safety of operating personnel and instrumentation. Jilin high-voltage transformer Which is better? Huayi Electric Power (certified), high-voltage transformers supplied by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
