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
The present invention relates to electromagnetic treadle, belong to Large Copacity contactor in electric-automation control system.
Background technology
Electromagnetic treadle is one of most popular electric component in electric-automation control system, and the main contact of existing electromagnetic treadle divides, close the normally open, normally closed state of action and auxiliary contact controls to realize by the coil switching electricity in a set of electromagnetic mechanism in a contactor body.Because main contact to act on point, closes high-current circuit, auxiliary contact acts on the interlocking, interlock, signal etc. that control other electric components, therefore electromagnetic treadle internal electrical magnetic mechanism M.E main contact point, close in action, auxiliary contact, then after keeping corresponding safe distance with main contact, realizes the synchronous normally open, normally closed state of auxiliary contact again by various forms of mechanical linkage which controls between main and auxiliary.The failure rate that (normally closed) state that what therefore existing electromagnetic treadle auxiliary contact was correct often open causes by mechanical linkage which controls fault is very high, particularly under frequent control or under severe operational environment, mechanical linkage which controls gets loose, wear and tear, aging etc. will directly cause a whole set of electric control system normally not run, if clamping stagnation, also the regular event of a whole set of electromagnetic mechanism of impact is burnt the phenomenon of electric main part and controlled electric equipment.
Summary of the invention
Technical problem to be solved by this invention is, the action needs of existing electromagnetic treadle auxiliary contact are directly met by designing a set of independently low capacity electromagnetic mechanism, thus the mechanical mechanism of contactor internal electrical magnetic mechanism interlock auxiliary contact can be cancelled, solve a series of electric faults that cause of mechanical mechanism fault because of contactor electromagnetic mechanism interlock auxiliary contact.
The present invention takes following technical scheme for solving the problems of the technologies described above.Electromagnetic contactor, comprise main contact electromagnetic mechanism and auxiliary contact electromagnetic mechanism, described main contact electromagnetic mechanism comprises initiatively contact, first drag link mechanism, main fixed contact, first motor magnet, first electrostatic magnet and the first coil, first electrostatic magnet is installed in the first lining shell, first electrostatic magnet and the first motor magnet are all in " mountain " font, first electrostatic magnet is positioned at the below of the first motor magnet and is mounted opposite, the intermediolateral column periphery of the first electrostatic magnet and the first motor magnet magnetic core is set with the first coil, outside two, magnetic post is equipped with the first spring relatively therebetween, the first drag link mechanism is equipped with in the top of the first motor magnet, initiatively contact is fixedly equipped with in the upper end of the first drag link mechanism, first drag link mechanism is set with main fixed contact, the contact relative match of main fixed contact and initiatively contact, outside first drag link mechanism, arc-extinguish chamber is housed, described auxiliary contact electromagnetic mechanism comprises dynamic auxiliary contact, second drag link mechanism, quiet auxiliary contact, second lining shell, second motor magnet, second spring, second electrostatic magnet and the second coil, second electrostatic magnet is installed in the second lining shell, second electrostatic magnet and the second motor magnet are all in " mountain " font, second electrostatic magnet is positioned at the below of the second motor magnet and is mounted opposite, the intermediolateral column periphery of the second electrostatic magnet and the second motor magnet magnetic core is set with the second coil, outside two magnetic post relatively between the second spring is housed, the second drag link mechanism is equipped with in the top of the second motor magnet, dynamic auxiliary contact is fixedly equipped with in the upper end of the second drag link mechanism, second drag link mechanism is set with quiet auxiliary contact, the contact relative match of quiet auxiliary contact and dynamic auxiliary contact, first coil of main contact electromagnetic mechanism and the second coils from parallel connection of coils of auxiliary contact electromagnetic mechanism.
The present invention is that a kind of electromagnetic type self contained function is in the electromagnetic contactor of auxiliary contact electromagnetic mechanism.Its advantage is that the auxiliary contact electromagnetic mechanism of contactor controls to realize Synchronization Control by a set of independently electromagnetic mechanism designed by connection main contact electromagnetic mechanism, overcome the shortcoming that the main and auxiliary contact synchronization action of contactor just must rely on mechanical coupling fashion to realize, just can cancel the mechanical linkage which controls between inner first motor magnet of former contactor and the second drag link mechanism.And due to without corresponding mechanical attachment, the installation of auxiliary contact electromagnetic mechanism both can with contactor body housing one, can be separated with contactor body again.Reduce mechanical clamping stagnation that existing kind contactor causes because interlocking mechanism mechanism is complicated, get loose, electric fault that the fault such as wearing and tearing causes, the security of operation of the controlled electric equipment of the electric controling element that is highly advantageous to.
