Embodiment

[0011] Example: The present invention cancels all the auxiliary contacts inside the liner shell of the original electromagnetic contactor and the mechanical mechanism linked with the main contact electromagnetic mechanism A (the linked mechanical mechanism is arranged between the first moving electromagnet 6 and the second pull rod mechanism 11) , add an electromagnetic mechanism under the auxiliary contact of the electromagnetic contactor and reinstall it in another set of electromagnetic mechanism, (see figure 1 ) The main contact electromagnetic mechanism A and the newly established auxiliary contact electromagnetic mechanism B synchronous action mechanism achieve the purpose of synchronous action after the first coil 9 and the second coil 17 are connected in parallel. The main contact electromagnetic mechanism A and auxiliary contact After the electromagnetic mechanism B is separated from the synchronous mechanical mechanism, the internal mechanical mechanism of the elect...

Abstract

The invention discloses an electromagnetic contactor. The electromagnetic contactor comprises a main contact electromagnetic mechanism and an auxiliary contact electromagnetic mechanism, wherein a first coil of the main contact electromagnetic mechanism and a second coil of the auxiliary contact electromagnetic mechanism are connected in parallel. The electromagnetic contactor independently acts on the auxiliary contact electromagnetic mechanism in an electromagnetic manner. After the control of the auxiliary contact electromagnetic mechanism of the contactor is further synchronously controlled by one set of independent electromagnetic mechanisms, the defect that the synchronous action of a main contact and an auxiliary contact of the contactor can only be realized in a mechanical connecting mode is overcome, electric failures caused by mechanical blockage, loosening, wear and other failures of the existing variety of contactor due to the complicated linkage mechanical mechanism are reduced, and safe running of electric equipment controlled by electric control elements is facilitated.

Description

technical field [0001] The invention relates to an electromagnetic contactor, belonging to a large-capacity contactor in an electric automation control system. Background technique [0002] The electromagnetic contactor is one of the most widely used electrical components in the electrical automation control system. The main contact opening and closing action of the existing electromagnetic contactor and the normally open and normally closed state control of the auxiliary contact are all controlled by a contactor. It is realized by turning on and off the coil in a set of electromagnetic mechanism in the device body. Since the main contact acts on the opening and closing of the high-current circuit, and the auxiliary contact acts on the interlocking, linkage, and signal control of other electrical components, the main force of the electromagnetic mechanism inside the electromagnetic contactor is in the main contact. In terms of closing action, while the auxiliary contact mai...
