(1) The parallel operation of transformers shall meet the following conditions: 1) The same winding connection group. 2) Same transformer ratio (allowable error 0. 5%). 3) The impedance voltage is the same (allowable error of 10%). 4) Capaci
具体来说，变压器噪声共有三个声源，一是铁心，二是绕组，三是冷却器，即空载、负载和冷却系统导致噪声之和。 铁心发作噪声原因是构成铁心硅钢片交变磁场效果下，会发作细小改
1, dry transformer long-term overload operation, windings by high temperature and burned, and even insulation fall off caused by turn or inter-layer short circuit. 2, the line short circuit protection failure, resulting in the transformer lo
The structure of Resolver is similar to that of two-phase winding induction motor, which can be divided into two parts: stator and rotor. The stator winding is the primary side of the transformer and the rotor winding is the secondary side o
1. The working principle of a rotating transformer. The magnetic flux distribution between the stator and the rotor of a rotating transformer conforms to the law of sine. Therefore, when the exciting voltage is applied to the stator windings
