The secondary voltage of lead electric defogger is low
Thread Content
Our factory uses a two-stage lead electric mist eliminator. After two months of operation, it was found that the secondary output voltage of the first-stage electric mist was reduced and it was difficult to increase, but the current was normal. The operation of the second-stage electric mist was also normal. Stopping and checking the interior, it was found that there was a small amount of attachments in the lead pipe. After flushing and driving, the problem was not significantly improved. From the lens inspection, no factors such as fog, discharge, extreme shaking, etc. were found inside. The electric heating insulation box is also normal. Please help analyze the cause of the failure and treatment measures, thank you. This post was last posted by Xiaofei on 2008-1-14 20:19 Edit ]
This depends on the type of high-voltage DC power supply. If it is a constant current source, it can well explain the above phenomenon.
I agree with the moderator, it's not a big deal in this situation.
What is the difference between constant current source and thyristor power supply? Electric mist appears with low voltage and high current. Voltage 42KV and current 350mA. This post was last edited by Xiaofei on 2008-1-14 20:35 ]
The low voltage is related to the form of the cathode wire, and many manufacturers do not understand this. For the first-level electrospray, you can choose a cathode wire with a higher current and a lower voltage. For the second-level electrospray, you can use an electrospray with a higher voltage and a smaller current. This has a lot to do with the structural outline of the cathode wire. Another point is that the voltage and current of the cathode wire are very good after installation. However, the voltage and current drop after one stage of use. This is because the cathode wire is not hung well. After one stage of use, eccentricity occurs.
