Prevent water and air from entering the transformer
Safety measures to prevent moisture and air from entering the transformer 1. The transformer must be well sealed during transportation and storage. During installation and operation, measures must be taken to prevent water from entering; during installation, attention must be paid to the parts higher than the oil surface of the oil pillow, such as […]
Dry-type transformer wiring method
Wiring Method of Dry-type Transformer 1. Short-circuit the “input” and “output” terminals of the Dry-type transformer to test the insulation resistance between the transformer and the ground wire with a megohmmeter. When measuring with a 1000V megohmmeter, the resistance is greater than 2M ohms. 2. The cross-section dry type transformer wiring of the input and […]
Transformer insulation
The main factors affecting the insulation performance of transformers During the operation of the transformer, the main factors affecting the insulation performance of the transformer are temperature, humidity, oil protection methods and overvoltage effects. Therefore, controlling these factors within a reasonable range is a key element to ensure the safe use of the transformer. Pad-mounted […]
Principle of resolver
Principle of resolver (signal transformation） The signal output of the resolver is a two-phase quadrature analog signal, and their amplitude changes with the angle of rotation, and the frequency is consistent with the excitation frequency. Such a signal can not be directly applied, which requires an angle data conversion circuit to convert such an analog […]
