3. Altitude: not exceeding 2500m;
4. No explosive hazardous medium around, and no gases or dust in the medium that can corrode metals and damage electrical insulation;
5. No significant impact vibration, and no place where rain or snow can intrude.
Structural Features:
1. This equipment consists of a control part (low voltage) and high-voltage rectification, discharge, and testing parts. Sufficient safety space is reserved between high and low voltage, and between high/low voltage and the enclosure.
2. To ensure the safety of equipment and personnel, a dedicated person must operate with a key before high voltage is started.
3. Each time fault detection or cable testing is performed, it is ensured that high voltage starts from zero and gradually increases. There are high and low voltage limit shapes. The voltage increase or decrease process is controlled by buttons, with smooth voltage change rate, safe and simple operation.
4. The DC withstand voltage test time can be automatically performed after the digital setting (or manually controlled), and the test time is accurate and reliable.
5. Leakage current can be measured at any time as needed during the withstand voltage test process.
6. The equipment has overcurrent and short-circuit protection, with start-up pre-alarm and overcurrent protection.
7. On the control panel, there are power switch, high voltage start, high voltage stop, voltage increase, voltage decrease switches or buttons, and a digital timer relay for withstand voltage test time, etc.
8. On the display panel, there are measuring meters for high voltage, leakage current, and low voltage total current, and indicator lights for power, high voltage, timing, and an observation window for ball gap discharge, etc.
9. A dedicated high-voltage discharge rod is provided for discharging after each fault detection or test to ensure safety. There is a grounding symbol at the bottom of the box.
