Product Description
The current transformer has epoxy resin cast fully enclosed structure. Applies to the rated voltage of 35kV and below. Rated frequency of 50Hz indoorpower line and its equipment current. Energy measurement and protection.Transformer is also known as the utility Transformer, is the current Transformer and voltage transformer collectively. Can turn high voltage into low voltage, large current into small current, used to measure or protect the system. Its main function is to convert high or large current into standard low voltage(100V) or standard small current(5A or 1A) in proportion so as to standardize and miniaturize measuring instruments, protective equipment and automatic control equipment. At the same time, the transformer can also be used to separate the high voltage system to ensure the safety of the person and equipment.
In power lines, the current difference from a few to a few thousand, voltage difference from several volts to several million volts. The current voltage in the line is high, so it is very dangerous to measure directly. To facilitate the conversion of the secondary instrument to a uniform current voltage, the Transformer is used to change current pressure and isolate electricity.
The instruments are mostly needle-type current voltmeters, so the secondary current of the current Transformer is mostly amped-grade(E. G. 5). With the development of the times, most of the power measurements have reached the digital, and the computer sampling signal is usually mA(0-5V, 4-20mA, etc.). The secondary current of the micro current Transformer is milliampere, which acts as a bridge between the large Transformer and the sample. The miniature current Transformer is called the "current Transformer for equipment". (`` Instrument Current Transformer "has a meaning that is used in laboratories for multicurrent than precise current Transformers, generally used to extend the meter range.
The current transformer primary winding and secondary winding. The ringcore and coil are encapsulated in epoxy resin cast insulator, pillar structure is fullyenclosed, with excellent insulation properties and moisture resistance. Can be wetor surface condensation and two filihy conditions under normal operation. lscharacterized by dynamic multiple secondary output capacity, accurate coeficientis higher than similar products. Insulation performance and stability.
