Autotransformer refers to a transformer whose windings are on the same winding. Its working principle is to wind two or more coils on a closed iron core. It is mainly used in occasions where one voltage needs to be changed to another voltage.

The wiring method of the transformer is roughly the same, whether it is a dry-type transformer or an oil-immersed transformer, we cut off the power when wiring, and then connect the live, neutral, and ground wires to the positions marked on the transformer.

Although both power UPS uninterruptible power supply and conventional UPS backup power supply have the same name (UPS) uninterruptible power supply, there are significant differences in structure and usage.

UPS, or uninterruptible power supply, is an uninterruptible power supply with an energy storage device. It is a power supply device that allows the load to continue working when the mains power is abnormal.

Uninterruptible power supply (UPS backup power supply) is a device that allows electrical equipment to continue working when the power supply is interrupted.

If the computer does not use an uninterruptible power supply, it is easy to lose the data in our work and cause damage to the data and computer hardware.

Online UPS uninterruptible power supply and backup UPS standby power supply are two common uninterruptible power supply devices. There are some differences between them in terms of battery power supply mode, response time, reliability and applicable scenarios.

The parallel operation of power transformers must meet the same voltage ratio of each transformer, each can only be viewed from a distance, the impedance voltage of the transformer is equal, and the wiring group of each electric transformer is the same.

When the power frequency UPS power supply is charged, it converts electrical energy into chemical energy and stores it. When a power grid failure occurs, the stored energy can be converted into electrical energy through an inverter to continue supplying to the load.

Both single-phase transformers and three-phase transformers are power equipment that rely on voltage induction to change current and electrical response. The difference lies in the application. Single-phase transformers are used in single-phase circuits, and three-phase transformers are used in industry and commerce. Of three-phase electricity.

Magnetic ring inductance coil is one of the common parts in electronic products such as household appliances, instruments and meters. In electronic circuits, AC signals are mainly isolated and filtered, and there are many types.

Proper use of uninterruptible power supply is necessary to ensure long-term normal operation of the equipment, and precautions should be read before use. Can keep UPS power supply working for a long time, reducing the occurrence of faults.
