NBI-BQ Cable Variable Frequency Series Resonance Withstand Voltage Test Device
Product Advantages
1. Cables with voltage levels of 35kV and below are used in large quantities, resulting in heavy testing workloads. Therefore, this type of withstand voltage test device is compact, lightweight, and portable, giving rise to the portable cable withstand voltage test system.
2. This system requires that components movable by a single person on site weigh no more than 30kg, and components movable by two persons weigh no more than 60kg, making it suitable for on-site handling.
3. The power supply uses 220V single-phase or 380V single-phase power, facilitating on-site power access.
4. The reactor part adopts dry-type epoxy casting, which is aesthetically pleasing and reliable, suitable for various cable requirements.
5. For cable withstand voltage tests at 110kV and above, oil-immersed reactors are used. When the single component weight exceeds 100kg, our company's special small electric hoist can be optionally equipped.
Product Introduction
The NRI-BQ cable-specific variable frequency series resonance voltage boosting device adjusts the frequency of the power supply to achieve resonance between the reactor and the test capacitor, obtaining high voltage and large current on the test object. It is a new method and trend in high-voltage testing and has been widely applied both domestically and internationally.
The NRI-BQ series variable frequency resonance voltage boosting device uses a dedicated SPWM digital waveform generation chip with a frequency resolution of 16 bits, achieving a frequency fineness of 0.1Hz in the range of 20-300Hz. It adopts an orthogonal non-synchronous fixed carrier modulation method to ensure good output waveform across the entire frequency range. The power section uses advanced IPM modules to ensure instrument stability and safety under minimal weight.
The NRI-BQ series variable frequency resonance voltage boosting device consists of a frequency and voltage regulating power supply, an excitation transformer, a reactor, and a capacitive voltage divider.
