Abstract
The utility model discloses a high performance energy saving AC contactor, which comprises a movable rod, main contacts, contact points, a coil, and an iron core. The movable rod is provided with three groups of main contacts; each group of main contacts is totally connected with a reset spring; one end of each group of main contacts is respectively connected with an output terminal; the other end is respectively connected with a normally closed contact points; the internal part of an action stroke of each main contact is respectively provided with a normally open points; the lower end of the movable rod is fixedly connected with an armature; a fixed iron core which is fixed onto a casing is arranged correspondingly to the armature; the coil is wound on the fixed iron core, and the lower part of the armature is connected with a reset spring. The high performance energy saving AC contactor can realize the automatic switchover of two-way electricity supply; devices are saved; use functions are added; the coil is controlled by the weak current; the electricity can be saved by 90%, and the automatic control is convenient. The high performance energy saving AC contactor is suitable for high-rise electric devices and automatic control devices.
Description
The utility model relates to a kind of A.C. contactor, particularly relates to a kind of energy-efficient A.C. contactor.
Existing A.C. contactor, main contact only have a normally opened contact, and coil is only controlled a contact action, and empty the setting walked in another contact, is a waste; If use on double-power supply switching device, will be with two A.C. contactors, the control panel of device strengthens, and the volume of device also strengthens thereupon, increase cost of manufacture and power consumption.
The purpose of this utility model is, a kind of double-contact that has is provided, and energy-efficient A.C. contactor is to overcome the deficiency of prior art.
Following mode can realize the utility model:
Energy-efficient A.C. contactor, comprise moving bar, main contact, contact, coil and iron core, on the moving bar three groups of main contacts are arranged, every group of main contact all links to each other with a back-moving spring, and an end of every group of main contact connects a lead-out terminal, the other end joins with normally-closed contact respectively, in the actuating length of each main contact, respectively establish a normally opened contact, the affixed armature in moving bar lower end, the fixed core and the armature that are packed on the housing are oppositely arranged, coil is on fixed core, and the armature below connects back-moving spring.
The utility model can be realized two-way control under the situation that does not increase unshakable in one's determination and coil, save material, is used on the automatic control equipment, saves the space, can little Current Control coil, realize big electric current contact action, and economize on electricity 90-100%, it is energy-efficient to survey title; Be convenient to and integrated circuit control end interface, being fit to automatically, the control electric supply installation uses.
Fig. 1 the utility model structural representation.
Embodiment:
The moving bar of A.C. contactor is evenly distributed with three groups of main contacts 13,14,15, back-moving spring 3 of the top connection of every group of main contact, back-moving spring 3 end in addition connects block 4, one end of every group of main contact connects lead-out terminal c, a b, a, and the other end links to each other with normally-closed contact 12-1,12-2,12-3 respectively.In the actuating length of each main contact 13,14,15, respectively establish a normally opened contact 11-1,11-2,11-3, the affixed armature 7 in moving bar 2 lower ends, armature 7 belows connect back-moving spring 10, the fixed core 9 that is packed on the housing is oppositely arranged with armature 7, coil 8 is on fixed core 9, the both sides of three groups of main contacts on moving bar 2, each installs one group of auxiliary contact, every group of auxiliary contact has two main contacts 16,17, dynamically connect between two normally-closed contacts 5 and 6, two main contacts of normally opened contact respectively and be equipped with back-moving spring 1.The course of work of A.C. contactor: normally-closed contact 12-1, the 12-2 of three groups of main contacts 13,14,15,12-3 respectively connect one road power supply L
1, L
2, L
3, normally opened contact 11-1,11-2,11-3 respectively connect another road power supply L
1＇, L
2＇, L
3＇, when connecting the power supply power supply of normally-closed contact, output a, b, c have electricity, work as L
1, L
2, L
3When not having electricity, coil 8 energisings, fixed core 9 produces magnetic force, overcomes the reaction force of spring 10, with armature 7 adhesives, moving simultaneously bar 2 moves downward, main contact 13,14,15 respectively with contact 11-1,11-2,11-31 closure, connect L
1＇, L
2＇, L
3The ＇ power supply; Or when coil 8 outages, or voltage is when significantly descending, and fixed core 9 magnetic force disappear, and armature 7 is with under the effect of the reaction force of spring 10, tripping, main contact 13,14,15 also returns under the effect of back-moving spring 3, thereby connects with another road power supply, and remaining output has, improved the operating efficiency of contactor, to be extinguished by arc-control device when the contact action produces electric arc, auxiliary contact is used for indication and control system, and coil 8 can be controlled by integrated circuit.
Claims (2)
