  • High impedance resistor device applied in high voltage environment
    Patent number: 9324482
    Abstract: A high impedance resistor device is applied in high voltage environment. The high impedance resistor device includes a voltage-endurance column, a first end, a second end, and a plurality of high impedance resistors. The first end and second end are configured at two ends of the voltage-endurance column. The plurality of high impedance resistors are connected to each other in series from the first end to the second end, and surrounded by the voltage-endurance column. The neighbored high impedance resistors are separated by an interval so as to avoid ash and water vapor accumulated at the connecting portion, and maintains the stability high impedance. The connecting portion between the two high impedance resistors is separated by a distance with the voltage-endurance column. And the connecting portion is configured a pellet connector to avoid point discharge phenomena.
