The invention discloses an overload protection system for electromechanical equipment, which includes a casing, a power supply is fixedly connected to one inner wall of the casing, a spring is fixedly connected to the outer wall of the power supply, and a machine box is connected to the other end of the spring. The spring runs through a side wall of the machine box and is fixedly connected to a moving plate at one end in the machine box, the moving plate is slidably connected to the inner wall of the machine box, and a groove is opened on the top of the moving plate away from the spring. A slide plate is matched and connected in the groove, and the inner wall of the machine box above the slide plate is provided with an accommodating groove that cooperates with the slide plate, and an electrically conductive electromagnet is respectively provided on the top of the accommodating groove and the top of the slide plate, and the accommodating groove A conductor layer is provided near the side wall of the spring, and a conductive turning block electrically connected to the conductor layer is provided on the other side of the conductor layer. The advantage is that by connecting a heat dissipation blade in series when the current is overcurrent, the size of the working current is reduced, and heat dissipation is performed at the same time, so as to avoid reducing the service life of the equipment.
Description
technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to an overload protection system for electromechanical equipment. Background technique [0002] Mechanical and electrical equipment generally refers to machinery, electrical appliances and electrical automation equipment. It is different from hardware, which refers to finished products that can achieve certain functions. [0003] Electromechanical equipment usually includes production equipment, information equipment and people's livelihood equipment. In the use of production equipment and information equipment, multiple electromechanical equipment is usually used to work at the same time to realize the functions of production and information collection. In this state, internal circuit aging or current overload may be caused, which cannot be self-detected and processed, thus causing problems such as short circuit or overcurrent, affecting use. Based on this, the...
