AI Technical Summary
The current-sensitive resistors in existing voltage transformer neutral point inrush current suppression devices are easily damaged, and their resistance is greatly affected by ambient temperature, resulting in inconvenient replacement and unstable performance.
An electromagnetic voltage transformer neutral point inrush current suppression device was designed, which adopts a parallel structure of multiple current-sensitive resistors. The current-sensitive resistors can be replaced through a quick connection mechanism, and the ambient temperature can be adjusted through an adjustable side plate structure to reduce the impact of temperature changes on the resistance value of the current-sensitive resistors.
This enables rapid replacement of the current-sensitive resistor and adjustment of the ambient temperature, improving the maintenance efficiency of the device and the stability of the current-sensitive resistor, and reducing the impact of ambient temperature on the resistance value.
