Detailed Product Description: | Voltage transformer divided by the number of phases: the vast majority of the product is a single-phase voltage transformer because of the small capacity, the plot is not the body, both inside and outside the three-phase high-voltage bushing between the insulation requirements difficult to meet, so only 3-15kV products Sometimes the use of a three-phase structure. 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, rated current of 5A or 1A high voltage transformer, not allowed to open. Principle one side N1 or less is usually a turn a few turns Beijing 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 secondary series of instruments and relays the current coil impedance is small Langfang high voltage transformer, 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 synthetic and synthetic magnetic flux value potential I0N1 Hengshui high voltage transformer is not large, the secondary side induced electromotive force E2 value does not exceed 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, secondary impedance is large, almost in no-load state, U2 does not affect U1, and with the changes reflect a voltage U1. Beijing high-voltage transformers, high voltage transformers, power is supplied by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) in high voltage circuit breakers this area devoted boundless enthusiasm and passion, Huayi Electric Power has been customer-centric, for customers to create the concept of value, quality, service to win market, and sincerely hope to cooperate with the community to create success, create brilliant.
