Many of the producers who sell frequency transformers on the market now have problems after they have bought them, have no idea how to fix them, do not know what problems will arise, and today the editor tells us what problems will arise。
1. Frequency transformers should not be placed on vibrating equipment, as a result of which the main circuit link screws within the transformer are easily loosed and many of the transformers are damaged by this announcement。
Connectivity problems: the input end of the frequency transformer is not too high for a single air switch to shield the current so that burning is not too severe in case of short circuits. Could not close temporary folder: %s control lines are as long as possible. This makes the control plate easily disturbed by electromagnetic waves and leads to the breakdown of the control plate beyond a good-use fence of 2 metres. No high current and often motion contactors should be attached to the frequency transformer, which, because of its particular distress, often leads to error in the movement of the variable (scatters of all kinds)。
3. The frequency transformers, which are often required to stop in a hurry, are better prepared not to use their own brakes, but rather to add an electric blackout or to introduce mechanical brakes, otherwise they are often subject to the electric counter-electric force and the error rate will advance dramatically。
Assuming that the frequency transformers often operate below 15hz at low speed, the electrics will also spread heat fans!
5. Dust and humidity are important issues for frequency converters. (c) dismantling of the frequency transformer in the air-conditioning room or in a cupboard equipped with a clean-up network to clean the dust on the circuit board and the heater in a timely manner; the shut-down of the frequency transformer is used to blow the circuit board with an electric wind before it is powered。
6. When some branded transformers break the heat fans, they do not release the heat until they break, so that when the fans sound, they should be replaced。
7. Some workshops are powered by generators, the voltage is constant, frequency transformers are often broken, generators are fitted with steady pressure or over-pressure and shielded, and they end well。
Mine awareness is also important. Of course, there are very few outbreaks, but when the transformer is struck by lightning, the damage will be heavy. The frequency transformer, which keeps water under constant pressure, is easily struck by lightning because it has a detonator that stretches to the sky。
9. In order to prevent electromagnetic wave disturbances, frequency transformers enter, export, and control lines so that they can use fences, which cannot be properly wired, or otherwise impregnated, with possible re-loading of pipes, filters and lower load frequency. We assume that the switch on the power source of the frequency transformer is a field effect tube (e. G., k series) which can be more troublesome。
When the frequency is broken, don't give it to someone who doesn't have a record! Sometimes it's going to melt, and there's a problem with checking, and some electricians don't have their résumés, and they put a good fast melting (which cannot be replaced with copper wires) on them, the effect of which is to burn down more severely. Based on our résumés, it is assumed that the fast-melting module is mostly problematic, but the module is fast-melting. Many of the variable power modules and the flow management modules are interchangeable。
These 10 points are the 10 questions that arise with respect to the maintenance of the frequency transformer。
