The body needs maintenance, the skin needs maintenance, the car needs maintenance, and the same low-power transformers also need maintenance during use.1. Prevent over-temperature: The temperature change should be monitored when the low-power transformer is running. Then if the transformer coil wire is A-class insulation, its insulator is mainly paper and cotton yarn, so the temperature has a grea read more
Let's take a simple look below:1. The basic working principle of the transformerIt is mainly introduced through the comparison of the two formulas, and professional people will understand it after reading it.E1=4.44fN1BmS and E2=4.44fN2BmS, current ratio and voltage ratio.2. Transformer no-load characteristicsFirst of all, we have to know the main magnetic flux Φm and leakage flux ΦL1, in natu read more
If the transformer fails, it will affect the safe and stable operation of the very important equipment in the power system. Once an accident occurs, it will cause great economic losses. Analyze various power transformer accidents, find out the reasons, sum up the methods to deal with the accident, control the accident loss to the minimum range, and minimize the damage to the system.Winding failure read more
1. Transformer bushing failureThe main manifestations are bushing flashover and explosion. The high-voltage side of the transformer generally uses capacitor bushings. Due to poor bushing porcelain or trachoma and cracks, the bushing is not tightly sealed, there is oil leakage, and the bushing is too fouled. Flashovers and explosions are possible.2. Core insulation failureThe transformer core is ma read more
In our life, many toroidal transformers are used. However, the winding method and precautions of toroidal transformer windings may not be clear to most netizens. Here we explain the specific operation methods and precautions for you:1. Wind the primary winding first, take the high-quality high-strength enameled wire with a similar diameter to the original wire, and wrap the double wire around the read more
