The invention discloses an overcurrent automatic circuit break protector. The device comprises a machine box and a circuit breaker box fixed at the bottom of the machine box. The machine box is vertically connected with a baffle in a sealed mode. The baffle and the inner wall of the machine box are horizontally connected with a metal plate in a sealed manner; the baffle and a second baffle dividethe machine box into a first liquid cavity, a second liquid cavity and a third liquid cavity; the top of the first liquid cavity is fixedly connected with another metal plate; the two metal plates form a parallel plate capacitor; and magnetorheological fluid is contained in the first liquid cavity, the second liquid cavity and the third liquid cavity. The advantages are that overcurrent can be detected, and for the overcurrent, a circuit can be recovered to be used after the circuit is disconnected for a period of time; when short-circuit current occurs, the power-off state can be kept continuously to prevent electric appliances from being damaged, and the initial state can be recovered by pressing the button; and operation is convenient, and the overcurrent automatic circuit break protector can be used repeatedly.
Description
technical field [0001] The invention relates to the technical field of power devices, in particular to an overcurrent automatic circuit breaker. Background technique [0002] Overcurrent refers to the amount of current passing through a conductor in excess of what is expected, resulting in excessive heating, and the risk of fire or damage. Possible causes of overcurrent include short circuits, excessive loads, improper design or ground faults, usually using fuses , circuit breakers, temperature sensors and current limiters to control the risk of overcurrent. [0003] In the use of household electrical appliances, the main causes of overcurrent are overload current and short-circuit current. In the prior art, fuses or circuit breakers are generally used to make short-circuit currents rely on the fusing of fuses at ultra-high temperatures. The circuit is disconnected, and because the overload current is not many times the rated current, the temperature rises slowly, that is, ...
