How to see the parameters from the nameplate

2022-06-29

Under the specified operating environment and operating conditions of the transformer, the main technical data are generally marked on the nameplate of the transformer. Mainly include: rated capacity, rated voltage and its tap, rated frequency, winding connection group and rated performance data (impedance voltage, no-load current, no-load loss and load loss) and total weight.

Confirm the power supply voltage (v) provided by the grid and the rated voltage (v) required by the electrical equipment to determine the voltage transformation ratio.

What are the environmental requirements for using waterproof potting transformers?

2022-06-29

The main feature of waterproof potting transformers is that they have the function of moisture-proof. The application of PCB circuit boards, waterproof transformers made of toroidal transformers, the main purpose is to prevent rain or waterproof immersion, and the main applications are outdoor lamps, urban lighting projects, mining areas, mines, Ship equipment, industrial atomizing humidifier. The potting transformer uses a high-frequency inductance transformer, or an EI low-frequency transformer below 5W. The protective casing (outer cover) is generally a plastic casing or an iron casing.

What are the faults of the transformer?

2022-06-28

There are many types of transformer faults, which are generally divided into local overheating, arc discharge, low-energy discharge, partial discharge, and insulation deterioration according to the nature of the fault.
