Talking about the Use of AC and DC High Voltage Dividers
The AC/DC high voltage divider is a special instrument for on-site measurement. It can not only measure the average value of DC high voltage, but also measure the effective value of AC high voltage. The whole equipment consists of a voltage divider and a measuring instrument.
The AC-DC high voltage divider adopts the balanced equipotential shield structure. Its internal uses high-quality electronic components and is installed in the insulating cylinder full of transformer oil, so that the entire device has the advantages of accurate test, good linearity, stable performance, reasonable structure, and easy It is an ideal instrument for on-site measurement because it is portable, simple to operate, and intuitive to display.
AC and DC high voltage divider use matters needing attention:
1. The device must not be surrounded by any foreign matter when used so as not to affect the measurement accuracy.
2. Strictly pay attention to maintain the operating distance and ensure safe operation.
3. Check the reliable connection of various parts, especially the solid ground connection.
4. After the measurement is completed, the meter will enter the site until the measurement shows zero.
5. It is forbidden to use overpressure and pay attention to the cleanliness of the surface. When not in use, it should be placed in a cool and dry place.
AC and DC high voltage divider instructions:
1. Open the aluminum alloy box and take out the pressure divider barrel, pressure equalizing ball, special digital measuring instrument and special cable.
2. Place the divider tube with the base securely and securely, and install the second section divider tube and pressure equalizing ball in turn.
3. Securely connect the ground wire to the “ground†terminal of the voltage divider base.
4. Connect the high voltage lead under test to the pressure equalizing ball at the top of the voltage divider.
5. Insert one end of the special cable into the output hole of the voltage divider, and the other end into the voltage measurement hole of the measuring instrument, pay attention to the tightness.
6. According to the high pressure to be measured, select the position where the measuring instrument was thrown.
7. Load high pressure and record data.
8. After depressurizing for a period of time, the main can remove the experimental line until the measuring instrument shows zero.
