FAQ summary

Problem: straight in use of red light, green light, the dc high voltage drop what reason be?

In the course of using the straight answer: high incidence in the above situation is related to protect action. At this time should be according to the following steps:
1)The pressure regulating potentiometer to return zero.
2)Shut off the power switch, panel lights are not bright.
3)A minute later, standby in low voltage capacitor discharge after fully, is allowed to open the power switch again. After no-load test again, and find out the situation, can boost pressure test again. If you have any other question also can call detailed consultation!


Question: after the power switch on the green light is not bright, what reason be?

Answer: there are two possible reasons:
1、The power cord short circuit.
2、Power blown fuse.
The solution: replace the power cord or fuse.


Question: the sample (s) for large capacitance discharge, can directly use electric discharge?

Answer: the sample (s) for large capacitance discharge, the discharge rod can not be immediately contact try to taste, should first will discharge rod gradually contact try to taste, to a certain distance began to free the air discharge accompanied by "hiss" sound. After waiting for the sound available electric discharge, finally ground discharge directly.


Question: how do you use the current limiting resistor?

Answer: when do the cable test, with the current limiting resistors must be end times pressure cone top connection, then the other end of the current limiting resistor is connected to a microampere meter. Note that only with capacitive resistor load test (including cable test) install and use, without having to use when do other test!


Problem: the dc high voltage generator when doing the pressure test cable burned out, what reason be?

Answer: the reason may have two aspects: On the one hand may be operation is not standard, not cut down the voltage and direct shutdown, causing current raced back to burn out straight high incidence; On the other hand may be because the current is too small, pressure rise too fast lead to burning instrument.


Problem: straight high-risk have automatic protection? If instruments don't work properly?

Answer: because the dc high voltage test has certain risk, so the research and development technology, especially emphasize and improve the product automatic protection function. Our product is over voltage, over current, Back to zero, grounding protection and special wire protection and other protective functions. In case of abnormal operating state, automatic protection device will start, stop to dc high voltage generator step-up process, And step-down to zero state. Our products are automatic protection function is strong, perfect and reliable protection mechanism, various technical indicators are better than the industry standard, more safe and convenient to use.


Question: 40 kv all-in-one dc high voltage generator no times how pressure cylinder booster?

Answer: 40 kv dc high voltage generator voltage double barrel is built-in, just connect the power cord, cable and ground wire is ok!


Problem: the dc high voltage generator can be used to mine the homework?

Answer: as long as the work environment conditions can be used, environmental conditions: temperature in - 10 ~ 40 ℃, relative humidity, room temperature is 25 ℃ is not greater than 85% (no condensation), Height: 1500 meters. 40 kv all-in-one is specially designed for operation under the mine.


Question: at 1000 v voltage measurement is accurate?

Answer: our dc high voltage generator is one of the advantages of stable performance and at the time of voltage up to 1000 v, control box on the voltmeter and ammeter readings will be very stable, there will be no digital instability, the phenomenon of floating up and down. This request has been far beyond the national standard requirements.


Problem: the dc high voltage generator can be used when the power supply?

Answer: the working principle of dc high voltage generator is 220 v alternating current into direct current high voltage, and then the use of dc high voltage in field test. So can also be called the dc high voltage generator instantaneous high voltage power supply. Need special attention is, this kind of high voltage continuous working time the longest cannot exceed 30 minutes (national standard), more than 30 minutes to instrument caused great damage.


Problem: the size of dc high voltage generator have an effect on safety performance? Is it the bigger the better?

Answer: the size is not a measure instrument of quality standards, we adopt the latest scientific research achievements, on the basis of guarantee the quality of products, produce such a small portable instrument, not only ensure the safety of products, customers and easy to use, well received by customers.
