How to use a DC high voltage generator
The DC high voltage generator is an instrument that supplies a high voltage DC source. The instrument must be reliably grounded before using the instrument. Workers who use DC high-voltage generators must have a “high-voltage test certificateâ€. To use the DC high voltage generator, the user must follow the provisions of Section 168 of the “Power Safety Regulations†and install two obvious breaking points before the working power supply enters the tester. When replacing the test sample and wiring, the two power supply disconnect points should be disconnected first. At the same time, at least three staff members must be on site to ensure the safety of the users. Before turning on the power on the instrument, be sure that the DC high voltage generator is connected to the 220V AC power supply. Check the wiring carefully and check the wiring of the high voltage discharge rod. In the process of buck-boosting of DC high-voltage generators, it is necessary to maintain a slow rise and fall, and smooth boosting is one of the main points of extending the service life of DC high-voltage generators. Also try to avoid over-the-counter use of the instrument. At the end of each test, the potentiometer is returned to the zero position, and then the power is cut off to discharge the test object. The discharge process is divided into two steps. For the discharge of the large capacitance sample, the ZS dedicated discharge resistance rod is used for the test sample. Discharge. 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. When the DC high voltage is 200kV and above, although the tester wears insulated shoes and is outside the safe distance, due to the influence of the electric field distribution of the high-voltage DC ion, several adjacent DCs have different DC potentials. . 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. The DC high voltage generator control box power supply is 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.
How to maintain 1. Change the hydraulic oil once a year and clean the fuel tank. The oil must be the recommended model;
2. Always check when the gas is hot (when the oil temperature is ≥ 45 degrees) whether the cooling device starts automatically. (The cooling water temperature must be below 30 degrees)
3. Clean the air filter while cleaning the fuel tank; Day 4. Always check the oil filter signal of the DC high voltage generator, the signal light is on (while the buzzer will sound), and the oil filter is cleaned immediately;
5. Fill the lubrication points of the mechanical transmission part of the equipment according to the regulations;
6. Always observe the liquid condition. When the liquid level is close to the lower limit, please promptly add the recommended hydraulic oil to the fuel tank.
7. Always check the dust-proof devices everywhere, and find that the damage or loose connections should be handled in time to prevent sand and dust from entering and damaging the equipment.
