Embodiment

[0023] refer to Figure 1-3 , an overcurrent protection processing device, comprising a fixed box 1 with a cavity, the inner wall of the fixed box 1 is welded with a fixed ring 2, the inner wall of the fixed ring 2 is rotatably connected to a turntable 3, and a conductive block 4 is embedded in the turntable 3 , the top wall of the fixed box 1 is fixedly connected with a sleeve 5, and the sleeve 5 is connected with a transmission structure;

[0024] The transmission structure includes a piston 6 that is sealed and slidably connected to the sleeve 5. An evaporating liquid is provided above the piston 6 in the sleeve 5. The evaporating liquid uses kerosene liquid with a boiling point of 150°C. The bottom of the piston 6 is fixedly connected with a push ring 7. The bottom of the push ring 7 runs through the inner wall of the sleeve 5, and the push ring 7 is sealed and slidingly connected with the sleeve 5. The bottom of the push ring 7 is fixedly connected with a first magnet 8, ...

Abstract

The invention discloses an overcurrent protection processing device. The device comprises a fixing box with a cavity. A fixing ring is welded to an inner wall of the fixing box, a rotary disc is rotatably connected to the inner wall of the fixing ring, a conductive block is embedded in the rotary disc, a sleeve is fixedly connected to a top wall of the fixing box, the sleeve is connected with a transmission structure, and the transmission structure includes a piston. A push ring is fixedly connected to a bottom of the piston, the bottom of the push ring penetrates through the inner wall of thesleeve, the push ring is in sealed sliding connection with the sleeve, a first magnet is fixedly connected to the bottom of the push ring, and a screw rod is rotatably connected to an outer wall of the sleeve through a bearing. The device has advantages that vaporization speeds of an evaporation liquid are different due to different magnitudes of a short-circuit current and an overload current during overcurrent; different adjustment of states of the two is realized in a system formed by a compression spring, a first magnet and a second magnet; and a self-recovery function and an effect are achieved.

Description

technical field [0001] The invention relates to the technical field related to electric power, in particular to an overcurrent protection processing device. 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 the overload current is not many times the rated current, and the temperature rises slowly, s...
