Detailed Product Description: | Voltage transformer primary winding to run by the state points: voltage transformer primary winding grounded: neutral grounding end single-phase or three-phase voltage transformer primary winding voltage transformer primary winding; ungrounded primary winding voltage Transformers: single-phase voltage transformer primary winding two ground terminals are insulated; all parts Zhenjiang three-phase high-voltage transformer voltage transformer primary winding, including terminals on the ground are insulated, and the insulation level and rated insulation consistent level. Transformers including CT and PT, is a high current, high voltage into a low current, low voltage for each measurement to protect the coil supply electrical equipment to reflect the operating parameters and fault conditions of the electrical equipment. (1) CT is equivalent to a short circuit operation of the transformer secondary winding in series with the metering and protection of high voltage transformers Yancheng, rated current of 5A or 1A, allowed to open. Principle one side N1 or less is usually a turn a few turns Taizhou high voltage transformers, N2 bigger. I1 depends entirely on the primary current (load current) nothing to do with I2 and load changes. This is different from the transformer. Under normal circumstances, the impedance of the second series of instruments and relays the current through the coil is very small, close to the short-circuit state, which is another different point from the power transformer. When the current transformer is working properly, the secondary current of the magnetomotive force generated by the secondary of a magnetomotive force I1N1 I2N2 from demagnetization effect. Therefore, the synthesis of magnetic potential I0N1 and synthetic flux value is not large, the secondary induced emf E2 value does not exceed several tens of volts. (2) PT is equivalent to an open transformer running, secondary and measurement, voltage coils in parallel to protect the instrument, rated voltage of 100V, not allowed to short circuit. Principle N1 "N2, a large high-voltage transformer secondary resistance, almost in no-load state, U2 does not affect U1, and with the changes reflect a voltage U1. Yancheng high voltage power transformers _ Huayi (certified) _ Xi'an high-voltage transformers supplied by 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. Huayi power in leadership with the staff warmly welcome all inquiries negotiations to create electricity Huayi a better future. |
