Problems solved by technology
[0002] The fuse is also called the current fuse, which is mainly used for overload protection. When the current abnormally rises to a certain height and heat, it will fuse itself to cut off the current to protect the safe operation of the circuit. The traditional fuse will not be in the current Occasionally, it will fuse when fluctuating, resulting in intermittent tripping when the current fluctuates, which affects the operation of the equipment and is very troublesome. People need to frequently toggle the switch, which is cumbersome. Therefore, a cooling protection device to prevent the circuit from overheating is urgently needed. To solve the above problems, the present invention improves on the above shortcomings

The invention discloses a cooling protection device for preventing a circuit from being overheated. The device comprises a working box and a working cavity formed in the working box. A fixed table isfixedly arranged on the bottom wall of the working cavity. A temperature control box capable of detecting temperature is fixedly arranged on the upper end surface of the fixed table. A temperature control cavity is formed in the temperature control box. A heat conduction rod is fixedly arranged on the left end surface of the temperature control box. According to the invention, circuit tripping isnot caused when current fluctuation is caused in a peak period of use. Therefore, the normal continuous operation of the equipment can be maintained, the air cooling device can cool the resistance wire when the current fluctuates so as to prevent the resistance wire from being fused, and when the current in the circuit is continuously abnormal, the metal fusion plate can adsorb heat in the resistance wire and fuse the resistance wire to play a role in protecting the circuit.
Description
technical field [0001] The invention relates to the technical field of emergency protection circuits, in particular to a cooling protection device for preventing circuit overheating. Background technique [0002] The fuse is also called the current fuse, which is mainly used for overload protection. When the current abnormally rises to a certain height and heat, it will fuse itself to cut off the current to protect the safe operation of the circuit. The traditional fuse will not be in the current Occasionally, it will fuse when fluctuating, resulting in intermittent tripping when the current fluctuates, which affects the operation of the equipment and is very troublesome. People need to frequently toggle the switch, which is cumbersome. Therefore, a cooling protection device to prevent the circuit from overheating is urgently needed. To solve the above-mentioned problems and aim at the above-mentioned shortcomings, the present invention makes improvements. Contents of the ...
