Abstract

The invention discloses electromechanical line overload protection equipment which comprises a shell, a power connection box is fixed to the inner wall of the shell, a power connection block is connected to the inner wall of the power connection box through a reset spring, a pair of power connection plates abutting against the power connection block is fixed to the inner wall of the power connection box. an electromagnet corresponding to the power connection block in position is fixed to the inner wall of the shell, a buffer box is fixed to the upper end of the electromagnet, a protection boxis inserted into the side wall of the shell in a penetrating mode, and a positive pressure block is fixed to the end of the power connection block. The overload protection equipment has the advantagesthat by arranging the electromagnet, when an overload phenomenon occurs in a circuit, the electromagnet can generate an effective strong magnetic field to attract the power connection block to move,so that the power connection block is separated from the power connection plate to disconnect the whole circuit, the safety of the circuit is protected, direct power failure is avoided in the early stage of overload; therefore, a certain time can be provided for the user to retrieve own misoperation without influencing the overall operation of the equipment, and the method is more reasonable and humanized.

Description

technical field [0001] The invention relates to the technical field of electromechanical equipment, in particular to an electromechanical circuit overload protection device. Background technique [0002] Electromechanical equipment generally refers to machinery, electrical appliances, and electrical automation equipment. In construction, it refers to the collective name of machinery and pipeline equipment other than geotechnical engineering, carpentry, steel bars, and muddy water. It is different from hardware and refers to finished products that can achieve certain functions; [0003] In order to ensure the normal operation of the equipment, it is generally necessary to protect the power lines of the equipment. Generally, fuses are used for circuit protection. However, the existing fuses either cannot be automatically restored and completely disconnected, or the circuit cannot be completely disconnected due to automatic recovery after a period of time. Open, and the lack of...
