Solutions to common problems of DC high voltage generator

Q: the green light doesn't come on after the power switch is turned on What's the reason? Answer: there may be two reasons: 1 The power line is short circuited 2 The power fuse is blown Solution: replace the power cord or fuse Q: what is the reason why the red light is off, the green light is on, and the DC high voltage drops? Answer: the occurrence of the above situation in the use of DHGF is the relevant protection action At this time, the following steps should be followed: 1 Return the potentiometer to the zero position 2 Turn off the power switch and the panel indicator is not on 3 It is allowed to turn on the power switch again one minute later after the low-voltage capacitor in standby is fully discharged After the no-load test is carried out again and the situation is found out, the boosting test can be carried out again If you have other questions, you can also call for detailed consultation! Q: when discharging large capacitance test object, can discharge directly with discharge rod? Answer: when discharging the large capacitance test object, it is not allowed to contact the discharge rod with the test object immediately First, the discharge rod shall gradually contact the test object, and when it reaches a certain distance, the air shall be free discharged with a "hiss" sound When there is no sound, the discharge rod can be used for discharging, and the Zui can be directly grounded for discharging How to use current limiting resistor? Answer: in the cable test, one end of the current limiting resistor should be connected with the upper end of the double voltage cylinder, and then the other end of the current limiting resistor should be connected with the microammeter Note that the current limiting resistor can only be installed and used when carrying out capacitive load test (including cable test), and it is not necessary to use it when carrying out other tests! Q: the DC high-voltage generator burned out during the cable withstand voltage test What's the reason? Answer: there may be two reasons: on the one hand, the operation is not standardized, the voltage is not reduced and the machine is shut down directly, resulting in the current back flushing and burning, and the direct high-frequency generator; on the other hand, the current is too small and the voltage rise is too fast, resulting in the burning of the instrument Q: is there automatic protection for DHF? What if the instrument doesn't work properly? A: as DC high voltage test has certain danger, it is particularly emphasized to improve the automatic protection function of the product when developing technology Our products have over-voltage, over-current [industrial electrical network cnelc], back to zero, grounding protection, special disconnection protection and other protection functions In case of abnormal operation, the automatic protection device will start, stop the boosting process of DC high voltage generator, and reduce the voltage to zero Our products have strong automatic protection function, perfect and reliable protection mechanism, and each technical index is superior to the industry standard, so they are more safe and convenient to use Q: how can a 40kV integrated DC high voltage generator boost voltage without a double pressure cylinder? A: 40kV DC high voltage generator double pressure cylinder is built-in type, as long as the power line, cable and ground wire are connected! Can the DC high voltage generator be used for underground operation? Answer: as long as the working environment conditions can be used, the environmental conditions are: the temperature is - 10 ~ 40 ℃, relative humidity: not more than 85% (no condensation) when the room temperature is 25 ℃, altitude: below 1500 meters The 40kV all-in-one machine is specially designed for the convenience of operation and use under the mine Q: is the reading still accurate when the voltage is 1000V? A: one of the advantages of our DC high voltage generator is that its performance is stable When the voltage rises to 1000V, the readings of the voltmeter and ammeter on the control box will be stable, and there will be no digital instability and fluctuation This requirement has far exceeded the requirements of national standards! Q: does the size of the DC high voltage generator have an impact on the safety performance? Is the bigger the better? Answer: volume size is not the standard to measure the quality of the instrument We use Zui's new scientific research achievements to produce such small and portable instrument on the basis of ensuring the quality of the product, which not only ensures the safety of the product, but also facilitates the use of customers, and is highly praised by the majority of users Can DC high voltage generator be used as power supply? Answer: the working principle of DC high-voltage generator is to convert 220V AC into DC high-voltage, and then use DC high-voltage for field test Therefore, DC high voltage generator can also be called instantaneous high voltage power supply It should be noted that the continuous working time of this kind of high-voltage electricity Zui cannot exceed 30 minutes (national standard), which will cause great damage to the instrument.
