Transformer action are the following: the primary circuit of high voltage and high current becomes standard position of the secondary circuit, generally rated secondary voltage of 100V, rated secondary current is 5A, so that test site instrumentation and protection equipment standardization , as well as insulation level can be low voltage secondary equipment design, thus light structure, and cheaper prices. All secondary equipment available low voltage, low current control cables, wiring within the screen simply a single, easy to install. At the same transformer, easy to focus on bamboo processing, it can be remotely controlled and measured. Secondary circuit is not a limit circuit. Can be Y-shaped, △ shaped or V-shaped connection, thus wiring flexibility. Meanwhile, the secondary equipment maintenance, as well as adjust the test replacement, without interrupting the operation of a system, only suitably changed secondary wiring can be realized. The secondary equipment and staff and the high-voltage part isolated and transformer secondary side are grounded, thus ensuring equipment and personal safety. The primary winding is adjustable, multi-winding current transformer secondary. This current transformer turns ratio range is characterized by multiple, and can be changed more common in high-voltage current transformer. Its primary winding is divided into two sections, each opening through the transformer core transformer secondary winding with taps into two different accuracy classes separate windings. The primary winding of the transformer and means connecting piece outside connections transformer factory outlets, by changing the position of the connection piece, so that the formation of the primary winding in series or parallel wiring, thus changing the number of turns of the primary winding to obtain a different ratio. Tapped secondary winding itself is divided into two different ratios and different level of accuracy of the winding, the primary winding is connected with the change sheet position, winding turns changed accordingly, it also changed the ratio of zero sequence current transformer device, thus forming a multi-range ratio. Different ratios and different accuracy classes with a secondary independent winding taps can be applied separately to power measurement, indicating instruments, transmitters, relay, etc., in order to meet their different requirements. _ Huayi power outlet transformer (certified) _ Taiyuan Huayi transformer provided by the Xi'an Electric Power Equipment Factory.
