The DC high voltage generator is a device that provides high voltage DC power. Before using the equipment, ensure that the equipment is grounded. Employees who use DC high-voltage generators need experts with "high-voltage test certificates". To use the DC high-voltage generator, the user must comply with Article 168 of the "Electrical Safety Regulations" and install two obvious disconnect points before the working power enters the tester. When replacing the wiring with the test product, you must first clearly disconnect the two power disconnect points. At the same time, there must be at least three workers on site to ensure the safety of users.
Before turning on the power of the device, please make sure to connect the DC high voltage generator to the 220V AC power supply, carefully check the wiring, and ensure that the high voltage discharge rod is reliable. please. During the step-up/step-down process of the DC high-voltage generator, a slow rise and deceleration must be maintained. A stable step-up is one of the key points to extend the life of the DC high-voltage generator. In addition, please do not use the device beyond the range. After each test, return the potentiometer to zero, turn off the power, and then eject the test product. The discharge process is divided into two stages. For the discharge of the large capacitor sample, the ZS special discharge resistance rod should be used to discharge the sample. When discharging, the discharge rod should not be brought into contact with the test product immediately. The discharge rod should be gradually approached to the test product. When the air gap is at a certain distance, it will begin to discharge freely with a hissing sound. When there is no sound, the discharge rod can be used for discharge, and then directly connected to the ground wire. Discharge. When the DC high voltage is 200kV or higher, the tester wears insulated shoes and is not within a safe distance. However, due to the influence of the spatial electric field distribution of the high voltage DC ion, the DC potential of the nearby human body will be different. The inspector shall not shake or touch the ground contact object. A slight electric shock will occur. This phenomenon is more obvious in dry areas and winter, but due to its low energy, it usually does not harm the human body.
