What should you watch out for when using a DC high voltage generator?
- Clicks: 829 Release time: 2012/5/26
The high-frequency DC high-voltage generator adopts pulse width modulation (PWM) technology, IGBT, and advanced electronic circuits and components. It has output protection from grid fluctuations, and has zero, overcurrent, breakdown, overvoltage and other protection measures. Over-current, breakdown, and over-voltage protection circuits can operate quickly, effectively protecting equipment and personnel. The output is liquid crystal display, and the volume and weight are much lighter than the original KGF type, which is very suitable for field use.
Precautions for use:
1. The user must follow the provisions of Article 168 of the “Electric Safety Regulations†and install two obvious breaking points before the working power enters the tester. When replacing the test sample and wiring, the two power supply disconnect points should be disconnected first.
2. The staff who use the high-frequency DC high-voltage generator must have the professional staff of the “high-voltage test certificateâ€.
3. For the discharge of large capacitor samples, the ZGF dedicated discharge resistance rod is used to discharge the sample. When discharging, the discharge rod should not be in contact with the sample immediately. The discharge rod should be gradually approached to the sample. The air discharge should start to discharge freely at a certain distance. There is a humming sound. When there is no sound, it can be discharged by the discharge rod. After the Zui, it can be directly connected to the ground. Line discharge.
4. Please check whether the grounding wires of all test wiring, control box, voltage doubler and test sample are connected before the test. The grounding wire of the test circuit shall be grounded at one point according to the requirements of this instrument manual.
5. When the DC voltage is 200KV or above, although the tester wears insulated shoes and is in a safe distance area, due to the influence of the high-voltage DC ion space electric field distribution, several nearby standing human bodies will have different DC power. Bit. The testers should not shake hands or touch the grounding body by hand, otherwise there will be a slight electric shock. This phenomenon is more obvious in dry areas and winter, but due to the small energy, it will not cause harm to the human body.
6, ZGF series Philippine high-frequency DC high-voltage generator control box power supply AC AC220V ± 10%, 50Hz. If the power supply is isolated by 1/1 or spontaneous power is used in the field, the power supply must be artificially connected to the ground.
