The invention provides an automatic closing circuit breaker which comprises a shell, a motor, a first gear, a transmission wheel, a second gear and a switch handle. The shell comprises a first shell and a second shell which are buckled and connected. The motor, the first gear, the transmission wheel, and the second gear are arranged in the first shell. The motor is connected to the first gear. The center of the first gear is provided with a through hole. The circumference of the through hole is provided with an arced boss as a gear boss. The transmission wheel and the second gear are coaxial structures. The transmission wheel is arranged in the through hole, and the teeth of the transmission wheel are buckled with the gear box. A spring is arranged between the transmission wheel and the second gear. One side of the transmission wheel is buckled with the second gear through pressing the spring. The teeth of the second gear are engaged with the teeth of the switch handle. According to the automatic closing circuit breaker, the problem that the automatic closing of a miniature circuit breaker can not be realized is solved through a mechanical structure, and the automatic closing circuit breaker has the advantages of simple structure, easy operation, and high safety factor.
Description
technical field [0001] The invention relates to the technical field of electric appliances, in particular to an automatic closing circuit breaker. Background technique [0002] Miniature circuit breaker, referred to as MCB (MicroCircuitBreaker), is the most widely used terminal protection device in building electrical terminal distribution equipment. It is used for single-phase and three-phase short-circuit, overload, overvoltage and other protections below 125A, including single-pole 1P, two-pole 2P, three-pole 3P, and four-pole 4P. [0003] At present, the miniature circuit breakers on the market cannot automatically adapt to the requirements of manual and automatic closing. However, the patent No. CN201420068862.3 applied by our company solves this problem. Since the technical solution of this patent is solved by means of electronic circuits, However, it cannot adapt to some scenarios that rely on mechanical structures, and the scope of application is relatively narrow. ...
