Product details
◆
This product is a capacitive equipotential shielding voltage divider high-voltage measuring device. Mainly used for measuring pulse high voltage, lightning high voltage, and power frequency high voltage. It is the preferred alternative to high-voltage AC/DC voltage dividers. It has the characteristics of easy operation, intuitive display, high accuracy, small size, and light weight, and is suitable as an ideal equipment for high-voltage measurement in power plants, substations, high-voltage electrical equipment manufacturing plants, and high-voltage testing laboratories.
This AC voltage divider is connected to the high voltage measuring end through an instrument line, which enables clear readings from a distance and is safe and convenient to use. This series of AC/DC voltage dividers has high input impedance and good linearity. Special shielding technology is used to reduce the impact of high voltage on the indication, thereby achieving high stability and linearity.
Using imported filling materials to make the structure smaller, lighter, more reliable, and reduce internal partial discharge. Small size, light weight, easy to carry, bringing great convenience to on-site inspection work.
Characteristics of AC/DC digital voltage divider (high-voltage meter)
1. High precision
The use of precision high-voltage thin film capacitors and precision high-voltage glass glaze resistors results in high input impedance, reduced test current, low power consumption, and improved measurement accuracy and stability of the instrument;
The signal processing part adopts high-performance OP for signal amplification, uses updated dual integral fraction AD sampling technology, four and a half bit LCD display, and has a higher resolution of 0.001kV. It is an upgraded product of high-voltage electrostatic voltmeter.
2. Good anti-interference performance
Adopting special shielding technology. The surface of the uniform pressure ball made of aluminum alloy material is smooth and shiny, effectively improving the electric field distribution around the uniform pressure ball, preventing tip discharge, and enhancing the anti-interference ability of measurement data. The low voltage display instrument adopts a fully metal enclosed structure shielding, and the high voltage divider and low voltage display meter are connected by high-quality coaxial cables to reduce the influence of high voltage on the indication, thereby achieving high stability and high linearity.
3. Safe and reliable
This instrument consists of a high voltage divider and a low voltage display instrument. The high voltage divider is filled with DuPont filling material from the United States and sealed with special technology. It has a smaller structure, lighter weight, and lower internal partial discharge, resulting in higher reliability. There is no oil leakage issue. The high voltage divider and low voltage instrument are connected by coaxial cables during operation, and the distance between the high and low voltage parts is relatively far, ensuring safe and reliable operation.
4. Easy to operate
Using a dip switch to switch between high and low voltage, AC and DC, convenient and fast. The four and a half digit LCD directly displays the measurement results, which is simple and intuitive. Bringing great convenience to on-site inspection work.
5. Convenient to carry
Adopting a portable structure, the whole machine uses an aluminum alloy packaging box as the chassis, which can be easily disassembled and assembled. Small size, light weight, easy to carry, and very convenient to use.
