Jszwk-10kv Outdoor Anti-Resonance Voltage Transformer

Product Description

JSZWK-10 anti-vibration three-phase voltage transformer is mainly insulated by epoxy resin and special insulating  materials. It is equipped with a protective iron box and a porcelain sleeve,  which improves the moisture-proof performance and electrical insulation performance. This product is not afraid of  frequency division, high frequency, It will be burnt due to overvoltage,  and it can run in the case of single-phase grounding of the line for a long time without over-temperature concerns. At  the same time, the protection winding generates a voltage of 100V to drive the relay to work.
This type of voltage transformer is a new type of voltage transformer developed and developed after the three-phase  five-column voltage transformer to eliminate the public nuisance of ferromagnetic resonance and a large number of burnt  out of the transformer due to the grounding of the power system to different degrees.

Product features and scope of use

The high voltage is converted into a standard secondary voltage of 100V or lower according to a proportional  relationship, which is used for protection, metering and instrumentation devices. At the same time,  the use of voltage transformers can isolate high voltages from electrical workers. Although the voltage transformer is  also a device that works according to the principle of electromagnetic induction,  its electromagnetic structure relationship is exactly opposite to that of the current transformer. The secondary circuit  of the voltage transformer is a high-impedance circuit,  and the magnitude of the secondary current is determined by the impedance of the circuit. When the secondary load  impedance decreases, the secondary current increases,  so that the primary current automatically increases a component to satisfy the electromagnetic balance relationship  between the primary and secondary sides. It can be said that the voltage transformer is a special transformer with  limited structure and use form. Simply put, it is the “detection element”.
