[0002] Circuit breakers are frequently used in high-voltage control equipment. High-voltage circuit breakers need to be used in high-voltage lines. Using high-voltage circuit breakers in high-voltage lines can protect high-voltage lines and prevent short-circuits in high-voltage lines. During the use of some circuit breakers, the power transformer needs to be installed outside the circuit breaker when some circuit breakers are in use, which increases the cost of using the circuit breaker, and some circuit breakers have poor insulation effect during use. It can ensure the safe and stable operation of the circuit breaker, which affects the use effect of the circuit breaker

The invention provides a novel high-voltage AC circuit breaker, which comprises a shell, wherein a current transformer and a power transformer are arranged in the shell; the current transformer can be located at the bottom; the power transformer can be located at the top; terminals are arranged at two sides of the shell and are lead-out terminals; the lead-out terminals are of a thread-like structure; a vacuum arc extinguishing device is arranged nearby the current transformer; and an insulating component is arranged at the lower part of the vacuum arc extinguishing device and is located at the bottom of the shell. A vacuum arc extinguishing chamber is arranged at the bottom of the shell, so that the using effect of the circuit breaker can be ensured. An insulating device is arranged at the lower part of the vacuum arc extinguishing chamber, so that the insulating effect of the circuit breaker is improved. A ground switch is arranged in the shell, so that the safety performance of the overall circuit breaker can be improved. A fixed cross arm is arranged in a lifting device, so that lifting and transporting of the circuit breaker can be facilitated.
