**Product Introduction & Features:**
This equipment is primarily used for testing the insulation level of various insulating materials, structures, and electrical products. It also serves as a power supply for partial discharge testing on devices such as transformers, current transformers, and surge arresters. It is widely used in electrical manufacturing, power operation departments, research institutes, and universities.
The HZJF system (10kVA/100kV) consists of the following components:
1. Test Control Cabinet
2. Free Gas Transformer
3. Coupling Capacitor
4. Protective Resistor
5. Isolation Filter
6. Partial Discharge Detector
7. Additional Accessories
The Hezhong control unit and PD-free testing transformer are responsible for controlling and boosting the voltage to the required level. The partial discharge detector captures and displays the partial discharge levels. The isolation filter helps reduce interference from the power supply, while the coupling capacitor transmits the partial discharge signal to the detector.
Key features include:
- 320x240 LCD screen with high-speed thermal printer
- HV voltage, HV current, LV voltage, LV current measurement mode
- High-precision sensors and 14-digit AD acquisition chip
- Real-time display of HV voltage, HV current, LV voltage, LV current, time, and withstand test results
- Zero-return detection for safe start-up
- Insulation resistance detection function
- Advanced PD-free epoxy insulating sleeve with minimal partial discharge
- Low impedance voltage
- Automatic control technology with strong anti-interference capability
- Rapid electronic protection for high reliability
