For dry-type transformers, the allowable temperature during operation is generally related to the heat resistance level of their insulation materials. The H-grade insulation paint has a temperature rise of 125K and a maximum allowable temperature of 180 ℃.

During the installation of low-voltage power distribution cabinets, it is mainly divided into top line entry mode and bottom line entry mode. During installation, we connect the power supply to the input terminal of the circuit breaker of the low-voltage power distribution cabinet, and its output end is based on actual needs. Connect to the output terminals of the circuit breaker of the power distribution cabinet.

The service life of the transformer is the longest among the entire components, and the failure rate is extremely low only when it is not destroyed by humans and when the load fails. However, excessive temperature rise is the cause of transformer failure.

SMD inductors belong to a large category under inductance, which can be divided into multiple sub-categories, such as: SMD shielded inductors, SMD unshielded inductors, SMD high current inductors, etc. The big difference between high-current chip inductors and ordinary inductors is that they can accept larger currents.

A transformer is an electrical device that uses the principle of electromagnetic induction to convert an AC voltage into another AC voltage without changing the frequency. The converted output voltage fluctuates with fluctuations in the input voltage.

When choosing a transformer, the sales staff will ask how big a transformer is needed, and this size represents two values, one is the power and the other is the capacity. The capacity of the transformer is related to whether the purchased transformer can be used.

A transformer is an electrical device composed of two or more coils. It is used to transfer electrical energy through a changing magnetic field. It is a way to convert electrical energy into magnetic energy, and then into electrical energy through magnetism. Its voltage conversion ratio and coil turns The numbers are more relevant.

The transformer power control box is a special supporting equipment for light transformers. The control box and table have the characteristics of convenient use and maintenance, superior

Transformers are closely related to our lives. It can be seen as large as the substation, as small as our circuit board. Transformers have a wide range of applications and many types.

When the transformer is purchased, installed and used, we must calculate the effective load of the transformer. At the rated power, the ratio of the output power of the transformer to the input power is called the efficiency of the transformer.

The temperature rise of the transformer is one of many important factors that directly affect the service life of the transformer, and the transformer has a temperature rise range, and different transformers have different temperature rise ranges.

The transformer is to transmit AC isolation and DC, which can realize voltage conversion, impedance conversion and phase conversion. The purpose of power transformer is power supply voltage conversion, and can provide multiple power supply voltages at the same time to meet the needs of the circuit.
