Type of 60kV Intelligent DC High Voltage Generator
Conventional High Voltage Generator
Utilizes transformers or voltage multiplier circuits to step up the input voltage to 60kV. Designed for steady-state output, it provides a continuous and stable high voltage ideal for applications requiring consistent electric fields.
AC High Voltage Generator
Produces alternating current at 60kV, typically at standard power frequencies (50/60 Hz) or variable frequencies. Ideal for simulating real-world AC stress conditions on electrical insulation.
Impulse High Voltage Generator
Designed to generate short-duration, high-magnitude voltage pulses that simulate lightning strikes or switching surges. Uses capacitor banks and spark gaps to produce standardized impulse waveforms (e.g., 1.2/50 μs).
Resonant Transformer High Voltage Generator
Employs an LC resonant circuit in conjunction with a high-voltage transformer to achieve 60kV output efficiently. Operates at the resonant frequency to minimize power loss and maximize voltage gain.
Applications of 60kV Intelligent DC High Voltage Generator
DC high-voltage generators can be used for various physical, chemical, and biological experiments in the laboratory, such as high-voltage electrical experiments, electrospinning, discharge experiments, etc.
DC high-voltage generators are widely used in the industrial field, mainly for electrostatic dust removal, heating of electric heating plates, electrode treatment of materials such as glass and rubber, electromagnetic isolation, electrolysis, and electrodeposition processes.
DC high-voltage generators can be used for medical diagnosis and treatment equipment, such as X-ray machines, CT scanners, nuclear medicine equipment, etc. They typically require high voltage to generate electron beams or accelerate ions for diagnosis and treatment of diseases.
DC high-voltage generators can be used for insulation tests, capacitor charging and discharging tests in power systems, as well as fault detection and positioning of transmission lines.
DC high-voltage generator is an important component of online particle accelerator. They are used to provide the required high voltage for particle accelerators to accelerate particles to high-energy states, for applications in basic physics research and nuclear technology.
Select a Safe Location: Place the generator in a dry, well-ventilated area away from moisture, flammable materials, and foot traffic. Avoid locations with high humidity or condensation to prevent electrical shorts or insulation breakdown.
Ground the Unit Properly: Connect the grounding terminal to a certified earth ground using a heavy-duty copper wire. Use a grounding rod driven into the earth if necessary. Proper grounding minimizes the risk of electric shock and stabilizes voltage output.
Connect Power Source
For DC models, connect to a compatible battery or regulated DC power supply. For AC models, plug into a grounded wall outlet matching the required voltage (typically 110V or 220V). Ensure all connections are tight and free of corrosion.
Set Voltage Control to Minimum
Before powering on, turn the voltage adjustment knob fully counterclockwise to the lowest setting. This prevents sudden high-voltage surges upon startup that could damage connected devices or the generator itself.
Verify Connections
Double-check all wiring, grounding, and input power connections. Confirm that no tools or conductive materials are near the output terminals
Maintenance
nsulation Resistance Testing
IConduct periodic insulation resistance and dielectric strength tests using megohmmeters or high-potential (hi-pot) testers to detect early signs of insulation degradation.
Visual Inspections
Check for physical damage, corrosion, loose connections, or overheating signs on terminals, cables, and housing. Pay special attention to bushings and connectors.
Component Cleaning
Dust, moisture, and contaminants can compromise electrical integrity. Use dry, lint-free cloths and approved cleaning agents to clean insulators and ventilation areas without damaging sensitive parts.
Thermal Imaging
Employ infrared thermography during operation to identify hotspots that may indicate internal faults or poor connections.
Environmental Monitoring
Ensure the operating environment remains within recommended temperature and humidity ranges to prevent condensation and thermal stress.
1.No Direct Contact: Never touch live terminals, connectors, or test points during operation. Even after shutdown, capacitors may retain dangerous charges—always discharge using proper grounding sticks.
2.Personal Protective Equipment (PPE): Wear high-voltage insulating gloves (Class 0 or higher), safety goggles, flame-resistant clothing, and dielectric footwear.
3.Clear Work Zone: Establish a controlled access area with warning signs and barriers. Maintain a minimum safe distance (typically 1–3 meters depending on configuration) from energized components.
04
Use Insulated Tools
Only employ tools rated for high-voltage work to prevent accidental conduction or arcing.
05
Proper Grounding
Ensure the generator frame and test setup are securely grounded using low-resistance cables to prevent floating potentials.
06
Monitoring Devices
Use voltage detectors, lockout/tagout (LOTO) systems, and interlocks to confirm de-energization before servicing.
07
Training
Only trained and authorized personnel should operate or maintain high-voltage equipment.
