This product adopts an indoor epoxy resin fully vacuum casting structure. Its surface creepage specific distance is greater than 25. mm/kV.
When the JSZJK-10Q voltage transformer is used in the system, each unit consists of four castings. The metering part consists of three voltage castings sleeved on the three-phase core columns, and the anti-resonance part is installed on another rectangular iron core. During normal operation, the neutral point voltage to the ground is zero volts, and the secondary output voltage of the anti-resonance part is zero volts. Once a phase-to-ground short circuit occurs, a voltage of 100V will be generated on the secondary side (da-dn) of the anti-resonance part, which drives the relay to act and cuts off the power supply. This neutral point has adopted anti-resonance measures, so that the product does not need to add additional anti-resonance or damping grounding and other protection methods, and can operate safely on the power grid. It can also operate for a long time in the fault line with single-phase grounding.
