Voltage measurement device for high-voltage direct-current electricity-transmission valve assembly, has lower round plate electrode connected with high-voltage arm resistor via insulating sleeve gasket

The device has a high-voltage arm resistor whose upper end is equipped with a high-voltage leading end and a lower end is provided with an insulating sleeve gasket. A lower round plate electrode is in insulating connection with the high-voltage arm resistor via the insulating sleeve gasket. A low-voltage arm comprises a shielding housing with a lower end cover and a circuit board. The circuit board is equipped with a packaged and parallely-connected low-voltage arm resistor and a low-voltage arm capacitor.
