Details HV2 type AC-DC high voltage measurement system: Performance and Applications: HV2 type AC-DC high voltage measuring system meets the requirements of GB311, measure DC average frequency ac rms, peak and peak / √2, the display of measured values It will also display waveform measurements. It is mainly used for power systems and electrical and electronic equipment manufacturing sector measure AC and DC high voltage. Main features:. HV2 type AC-DC high voltage measuring system using a specially designed high and low arm with oil paper foil capacitors, and the choice of the electrical strength greater than 50kV / 25mm 12 alkyl benzene oil, high pressure resistance temperature coefficient of capacitance element ≤50ppM, having high accuracy, good temperature characteristics. The instrument in the low pressure measurement arm without any adjustable device, does not exist due to vibration caused by the displacement of the adjustable point affect the precision, high reliability. The measuring section and a display section completely separate, safe and reliable. . Using a portable, easy to use. The display section with large-screen LCD display, can display measurement data and waveform. The measuring system is designed to meet the requirements of GB311. The main technical indicators: Voltage rating: 50kV, 100kV, 200kV, 300kV, 400kV partial pressure ratio: 1000: 1 Accuracy: single double DC 0.5 AC 1.0 1.0 1.5 Measurement frequency: 30 ~ 300Hz Input impedance: 150pF / 400MΩ Electric Strength : Overview of 1.2 times the rated voltage AC and DC high voltage measurement system (divider) is a dedicated site measurement instruments, either the average of the DC high voltage measurement, but also high voltage ac rms measurement, the entire device from the divider and composed of two parts measuring instruments. Other potential divider adopts balanced shield structure, its internal use of high-quality electronic components, and is mounted on an insulating tube filled with transformer oil, so that the entire device has a test is accurate, linear, stable performance, reasonable structure, easy to carry and operate Simple, intuitive display, etc., so it is the ideal instrument field measurements. Technical Specifications 1. Standard: DL / T 846.1-2004 2. Voltage rating: AC: 150kV DC: 150kV 3. Measurement accuracy: AC: 0.5 级 DC: 0.5 4. Working environment: Temperature: -5 ℃ -40 ℃ Humidity: ≤85% 5. Input Impedance: 800MΩ 6. Output Impedance: 0.8MΩ 7. High and low partial pressure ratio: 1500: 1 Description AC-DC high voltage measuring system (divider) in combination divider dividing by a two-cylinder, two-part must use reliable connection. 1. Open the aluminum box, remove the divider tube, equalizing the ball, dedicated digital gauges and special cable. 2. Will have a base of splitter cylinder safe place, turn fitted with the second quarter and were divider cylinder pressure ball (see Figure 1). 3. On the divider base "ground" is firmly connected to the ground terminal. 4. The measured voltage lead and voltage divider top equalizing ball securely connected. 5. The end of the special cable insertion hole divider output, and the other end into a hole measuring instruments voltage measurement, note inserted immediately after prison. 6. According to the required high voltage measurements, select the measurement instruments are throwing position. 7. High pressure loads and record the data. 8. Buck for some time, until the measuring instrument displays zero, the main test lines can be removed. Notes 1. AC-DC high voltage measuring system (divider) use without any debris around, so as not to affect the measurement accuracy. 2. Strictly keep operating distance, to ensure safe operation. 3. Check all parts reliable connection, especially solid ground connection. 4. After measurement until the meter measurements show zero before entering the site. 5. Prohibited use of excess pressure, and pay attention to surface cleaning, when not in use in a cool dry place.
