In shenzhen, many people have purchased different watts of retrovert power, and there are many problems with the most malfunctioning power, so where is the retrovert vulnerable
Inverters are the most vulnerable to damage from front-level power boosters in power products. The second is the line, which some users like to take down machines, and then accidentally break some of the lines inside, causing the reverse to be damaged。
1. Low electrical insulation
Use exclusion methods. Draws the reverser to enter all strings on the side, and then connects. Insulation, detection of problem strings, search of problem strings, and checking whether dc connectors have short-circuit stands immersed in water are used for insulation. Or burn the short-circuit stand and check if the component itself has burned the black spot on the edge, thereby causing the component to leak to the ground through the frame。
2. Low main-line voltage
If it occurs in the early/late stages, it is a normal issue because the reverser is trying to limit the conditions for generating electricity. If it occurs during normal daytime, the test method is still the exclusion method and the test method is the same as one。
3. Flow failure
The root causes of such problems are the quality of the installation, the selection of the wrong place of installation and the poor quality of the equipment. There are many fault points: poor straight-flow connectors, poor-quality components, low-quality components installed at a height, poor-quality netting equipment or leaks. In case of similar problems, you can find ** points and spread the powder. A good insulation would solve the problem and, if it was a matter of material, it could be replaced only。
4. Direct flow through pressure protection
As components seek to improve efficient processes, their power levels are constantly updated and their opening and working voltage increases. The temperature factor must be considered during the design phase to avoid hard damage due to overpressure at low temperatures。
Five, no reversible. Response
Please ensure that the straight-flow input line is not reversed. The dc connection usually has a dementia effect, but the compressor does not have a dementia effect. It is important to carefully read the inverters manual to ensure that positive and negative ends are attached together. The reverser has built-in reverse short circuit protection and can be activated normally upon return to normal connection。
