What are the causes and solutions of no-load current of scb1

Scb10 dry-type transformer can control the current and voltage in the circuit, but it also has its own current and voltage. For scb10 dry-type transformer, it is necessary to enhance the control function of current and voltage of scb10 dry-type transformer. For current, it is necessary to enhance the purpose of various voltages and currents of scb10 dry-type transformer, so that scb10 dry-type transformer can be used orderly. The common problem of scb10 dry-type transformer current is no-load, which directly affects the performance and efficiency of scb10 dry-type transformer. Under the direct effect of the no-load current of scb10 dry-type transformer, the utilization rate is very low, and the conversion rate is not high. Therefore, the no-load current of scb10 dry-type transformer can not be ignored, and it should be solved immediately.

　The no-load current of scb10 dry-type transformer is composed of magnetization current (producing magnetic flux) and iron loss current (caused by iron core loss). According to the recommended values of relevant standards and a lot of practice, the maximum no-load current IIO of scb10 dry-type transformer for small power supply should not exceed 5-8% of IIO. If the no-load current exceeds 10% of the rated current, the loss of scb10 dry-type transformer will increase; when the no-load current exceeds 20% of the rated current, scb10 dry-type transformer can not be used, because its temperature rise will exceed the allowable value, and the working time will be a little longer, which will lead to serious burning accident. Therefore, the smaller the no-load current of scb10 dry-type transformer, the better.
