The control transformer can change the voltage, impedance, and even current to meet different requirements. Purchase and use of transformers need to pay attention to the following matters:
1, before the purchase of the control transformer, it is necessary to estimate the total capacity of the electrical appliance, and to leave a margin, so as to avoid the transformer being burned out when it is started instantaneously.
2, winding power transformer, then should strictly control the power of each winding, so as not to burn the transformer.
3, before the installation of the control transformer, the data parameters should be checked to see if they meet the requirements, and after the inspection, the transformer can be put into use.
4, when the transformer is running, pay attention to whether there is abnormal heating, if there is abnormal, it should be handled in time.
