Your question is quite professional, and people who have never touched it will basically not understand it. To tell you the truth, I don't know much about isolation transformers, but I am very interested in seeing this problem. Let's discuss and learn about the isolation transformer! Circuit breaker (English name: circuit breaker) refers to a switching device that can turn on, carry and turn off current under normal circuit conditions, and can turn on, carry and turn off current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electric energy, not always start asynchronous motors, protect power supply lines and motors, and automatically cut off circuits in case of serious faults such as overload, short circuit and undervoltage. Their functions are equivalent to the combination of fuse switches and overheating and underheating relays. Moreover, it is generally not necessary to replace parts after breaking the fault current. It has been widely used at present. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to the scope of application. The boundary between high voltage and low voltage is vague, and those above 3kV are generally called high voltage appliances. In modern society, electricity is indispensable to industry, agriculture, transportation, national defense, culture, education and health, finance, commerce, tourism services and people's lives. Power distribution is an extremely important link in power generation, transmission and consumption. The distribution system includes transformers and various high and low voltage electrical equipment, and low voltage circuit breakers are widely used electrical appliances. According to the provisions of national technical standards, the model of circuit breaker is generally composed of characters and numbers in the following ways: its representative meaning is: ① product letter code, represented by the following letters: S- less oil circuit breaker; D- oil circuit breaker; K- air switch; L- sulfur hexafluoride circuit breaker; Z- vacuum circuit breaker; Q- gas circuit breaker; C- magnetic blow circuit breaker. ② —— Equipment location code; Indoor, outdoor. ③ —— serial number of design series; It is represented by the numbers 1, 2, 3. ④—Rated voltage, KV. ⑤ —— Other supplementary operation characteristic signs, G —— improvement, F —— split-phase operation. ⑥-rated current, a.⑦-rated breaking current, KA. ⑧ —— Special environment code. Like DZ47-63, it means open. If DZ47LE-63 leaks water. C 16: refers to the current of 16A. Generally, it is for domestic use, and it is above C32 in engineering. That's all for the circuit breaker. I learned a lot when I was looking for information. I wonder if the answer I gave you is what you want? Having said so much, do you understand? I hope my answer can help you. If you are satisfied with my answer, just give me a smile, hehe ~ I will continue to work hard ~
