First of all, we need to know the classification of transformers. What we often see should be distribution transformers below 10-35 kV, generally 10 kV or 0.4 kV.
The problem of circuit faults in transformers mainly refers to the occurrence of short circuits at the outlet of the transformer, as well as short circuits to ground between the leads or windings inside the transformer, and short circuits caused by phase to phase faults. In fact, this type of fault is a very common problem among many faults in actual power transformers, and there are also many practical cases of this fault.
The electronic transformer is also a switching power supply. It is actually an inverter. First, the AC power is converted into DC power, and then the electronic components are used to form an oscillator.
In modern power systems, the construction and maintenance of distribution stations are crucial. As an emerging power infrastructure, prefabricated distribution stations have gradually attracted widespread attention due to their high efficiency, flexibility and economy.
A circuit breaker is a device that protects circuits, mainly used to prevent overload and short circuit problems of electrical equipment. Circuit breakers are widely used in power systems, construction, industry, and transportation. The specific uses are as follows:
PV AC combiner box refers to a box that combines the output currents of multiple PV inverters into a combiner box, which is then connected to a circuit of an integrated switch cabinet in the on-site power distribution system to realize the combining and AC conversion functions of multiple PV inverters. It is an important part of the PV power station.
