Problems solved by technology

[0002] At present, electromagnetic AC contactors are still widely used in industrial automation control equipment. Ordinary electromagnetic AC contactors must continue to supply power to the electromagnetic coils in order to maintain operation. This operating mode not only consumes energy but also generates electromagnetic noise, often due to The temperature rises and the aging burns out the electromagnetic coil

Abstract

An electromagnetic energy-saving and noise-suppressing AC contactor, in which a center tie rod is arranged on the moving iron core of the contactor and the crossbeam of the contact bracket, a locking nut adjustable chuck is arranged at the end of the center tie rod, and a bore is arranged on the static iron core ,Concave shaft hole, and set concave shaft, set small bearings on both sides of the concave shaft hole, set compression spring at one end of the concave shaft, force rod, suction cup type small electromagnet, on the other end of the concave shaft and the slide rail Set the anti-loosening nut, the linkage spring lug, and set the linkage spring, set the small electromagnet magnetic suction bracket on the side of the static iron core, set the control circuit module at both ends of the control terminal of the contactor, and control it in series in the main electromagnetic coil Small relay normally closed contacts in the module.

Description

technical field [0001] The invention relates to an electromagnetic AC contactor, in particular to an electromagnetic energy-saving and noise-suppressing AC contactor. Background technique [0002] At present, electromagnetic AC contactors are still widely used in industrial automation control equipment. Ordinary electromagnetic AC contactors must continue to supply power to the electromagnetic coils in order to maintain operation. This operating mode not only consumes energy but also generates electromagnetic noise, often due to The temperature rises and burns out the electromagnetic coil. Therefore, it is a technical problem to be solved at present to design an electromagnetic energy-saving noise-suppression AC contactor to replace the traditional electromagnetic AC contactor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electromagnetic energy-saving and noise-suppressing AC contactor. [0004] The techn...
