摘要（英）：

The utility model relates to a sampling device for measuring the voltage of a high-voltage line. The sampling device comprises a high-voltage resistor used to be connected on the high-voltage line tobe tested, wherein, the two lead ends of the high-voltage resistor correspond to the high potential and the low potential of the high-voltage line to be tested respectively, the sampling device further comprises a Hall sensor used for detecting current flowing through the high-voltage resistor, the Hall sensor is sleeved on either the high-voltage resistor or a conducting wire connecting either ofthe lead ends of the high-voltage resistor and the high-voltage line to be tested, the output end of the Hall sensor is connected to the input end of a operation amplifier, and the output end of theoperation amplifier is used to be connected to a voltage measurement device. The utility model is used to solve the problems in the conventional sampling method, such as complex design, difficulty inisolation, high failure rate and low reliability.
