Q: The green light does not light after the power switch is turned on. What is the reason?
A: There may be two reasons:
1. The power line is shorted.
2. The power fuse is blown.
Solution: Replace the power cord or fuse.
Q: The straight high light is off during use, the green light is on, and the DC high voltage is falling. What is the reason?
A: The above situation occurs during the use of straight high hair, which is the relevant protection action. In this case, you should follow these steps:
1. Return the piezoelectric positioner to the zero position.
2. Turn off the power switch and the panel indicators are off.
3. After one minute, the standby low voltage capacitor is fully discharged before allowing the power switch to be turned on again. After the no-load test is repeated and the situation is ascertained, the test can be boosted again. If you have any other questions, you can call us for details!
Q: When discharging a large capacitor sample, can it be discharged directly with the discharge rod?
Answer: When discharging a large capacitor sample, the discharge rod should not be in contact with the sample immediately. The discharge rod should be gradually contacted with the sample. At a certain distance, the air will be freely discharged with a “click†sound. After the sound is not available, it can be discharged by the discharge rod, and the ground wire is discharged after the Zui.
Q: How is the current limiting resistor used?
Answer: When doing cable test, connect one end of the current limiting resistor to the upper end of the voltage doubler, and then connect the other end of the current limiting resistor to the microampere meter.
Note that the current limiting resistor can only be installed and used during the capacitive load test (including the cable test), and it is not necessary to use it for other tests!
Q: The DC high voltage generator burned out when doing the cable withstand voltage test. What is the reason?
A: There are two reasons for this:
On the one hand, it may be that the operation is not standardized, the voltage is lowered and the power is turned off directly, causing the current to be burned back and burned straight; on the other hand, it may be because the current is too small, and the boosting is too fast, causing the instrument to burn.
Q: Is there a automatic protection for straight high hair? What if the instrument is not working properly?
Answer: Because the DC high voltage test has certain risks, especially in the research and development of technology, the automatic protection function of the product is emphasized. Our products have various protection functions such as overvoltage and overcurrent [industrial electrical network-cnelc], zero return, grounding protection, and special disconnection protection. In the event of abnormal operation, the automatic protection device will start, stop the DC high voltage generator boosting process, and step down to the zero state. Our products have strong automatic protection function, perfect protection mechanism, and all technical indicators are superior to industry standards, making it safer and more convenient to use.
Q: How does the 40KV all-in-one DC high-voltage generator boost without a double-pressure cylinder?
Answer: The 40KV DC high voltage generator voltage doubler is built-in. Just connect the power cable, cable and ground wire.
Q: Can DC high voltage generators be used in mine operations?
A: As long as the working environment conditions can be used, the environmental conditions are: temperature is -10 ~ 40 ° C, relative humidity: room temperature is 25 ° C when not more than 85% (no condensation), altitude: 1500 meters. The 40KV all-in-one is specially designed for easy operation under the mine.
Q: Is the reading measured at 1000V accurate?
A: One of the advantages of our DC high voltage generator is that the performance is stable. When the voltage rises to 1000V, the display of the voltmeter and ammeter on the control box will be stable, and there will be no digital instability or floating up and down. This requirement has gone far beyond the requirements of national standards!
Q: Does the size of the DC high voltage generator have an impact on safety performance? Is it bigger, the better?
A: The size is not the standard for measuring the quality of the instrument. We use zui's new scientific research results to produce such a 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 the customer. Praised by the majority of users.
Q: Can the DC high voltage generator be used as a power source?
Answer: The working principle of DC high voltage generator is to convert 220V AC into DC high voltage, and then use DC high voltage power for field test. Therefore, the DC high voltage generator can also be called an instantaneous high voltage power supply. It is important to note that this high-voltage continuous working time cannot exceed 30 minutes (national standard), and more than 30 minutes will cause great damage to the instrument.
