A high-speed and long-life electromagnetic mechanism relates to the technical field of electromagnetic mechanisms. The lower casing and the upper casing are fixedly connected, and the shock absorbing pad is installed at the bottom of the lower casing. The core fixing pressure plate is fixed on the lower shell; the retaining electromagnet shell set is fixed on the lower shell, the retaining electromagnet coil is set in the retaining electromagnet shell, the retaining electromagnet action core rod is set in the retaining electromagnet coil, and the retaining electromagnet One end of the back-moving spring sticks to the action core rod of the maintenance electromagnet, and the other end sticks to the coil of the maintenance electromagnet. The casing of the self-locking mechanism is fixed on the static iron core, the sliding link is hinged and slidably fixed inside the casing of the self-locking mechanism, the movable pull rod of the self-locking mechanism is hinged and fixed inside the casing of the self-locking mechanism, and a reset device is installed under the movable pull rod of the self-locking mechanism tension spring. It can solve the problems of high energy consumption of the existing electromagnetic mechanism, slow closing and opening speed of the upper and lower iron cores, easy burning of the upper and lower contacts, and easy arcing of the upper and lower contacts.
Description
Technical field: [0001] The invention relates to the technical field of electromagnetic mechanisms, in particular to a high-speed and long-life electromagnetic mechanism. Background technique: [0002] The existing electromagnetic mechanism uses the coil to energize the upper and lower iron cores to close. In order to keep the closure, the electromagnetic coil is always in the energized state, which not only reduces the service life of the electromagnetic coil, but also keeps the temperature of the electromagnetic coil at a relatively high level. , causing the aging speed of the electromagnetic coil to be extremely fast, which seriously affects the suction force and closing speed of the electromagnet. Therefore, it is more common for the solenoid coil of the contactor to burn out. [0003] Another thing is that the iron core has to overcome the resistance of the return spring during the closing process, which results in a decrease in the closing speed of the iron core. In ...
