6-35KV distribution power network in China, neutral point potential with no grounding, arc suppression coil grounding, high resistance grounding, grounding, resistance in low resistance grounding, grounding mode. YX-ZT transformer neutral point Baoding Yuxin Electrical Company Limited production of grounding resistance cabinet is suitable for resistance grounding mode. The series are widely used in electric power plant auxiliary system, system, industrial and mining enterprises distribution system, 6-35KV AC power supply substation transformer or generator neutral point, in order to realize the network neutral point grounding through resistance method.
Features two, the product
YX-ZT transformer neutral grounding resistor cabinet resistors used special non-metallic materials preparation and sintering resistance valve sheet or imported nickel chromium alloy belt, has the advantages of high resistivity, stable performance, high temperature resistance, flow ability. Has the advantages of small size, long working time, big range of resistance, but also can be equipped with a current transformer and action recorder, can monitor the neutral point unbalance current is normal, single phase to ground fault, can record the action times. And to the protection and monitoring system with analog output.
YX - ZT transformer neutral grounding resistor cabinet as standard products, with resistance or reactance parallel operation. As the network gradually expanded and grounding resistance decreases provides a convenient.
When the transformer winding is connected to the installation of Z triangle independent winding grounding transformer, YX-ZT transformer neutral grounding resistor cabinet and can be matched with the.
