Abstract
The utility model relates to a magnetic lock alternating current contactor with a wire package, no need of long-term energization and power-saving property, which comprises an outer shell, an inner shell, a main contact, an auxiliary contact, the wire package, an iron core, an armature, a spring, two connected buttons and the like, wherein the iron core is made of half-permanent magnetic material, and the wire package adopts the forward and backward direct current alternate instant power supply operation. The starting power supply time and the stopping power supply time of the magnetic lock alternating current contactor are very short, and the contactor can keep working by utilizing the residual magnetism of the iron core without electricity, thereby being power-saving and having no noise.
Description
Affiliated technical field
The utility model relates to the device of a kind of remote connection and disjunction alternating current circuit, especially the line bag need not switch on for a long time the economize on electricity the magnetic padlock A.C. contactor.
Background technology
Present existing A.C. contactor, it is made up of shell, inner casing, main and auxiliary contact line bag, iron core, armature etc., and the wide consumption of its use is very big, and is safe and reliable, but exists the line bag to need the big deficiency of long-time energising power consumption.
Summary of the invention
Exist the line bag to need the big deficiency of long-time energising power consumption, the magnetic padlock A.C. contactor that the purpose of this utility model provides a kind of line bag need not switch on economize on electricity for a long time in order to overcome existing A.C. contactor.
The technical scheme that the utility model technical solution problem is adopted is: it is made up of shell, inner casing, main and auxiliary contact, line bag, iron core, armature, spring, doubly-linked button etc., wherein, iron core adopts semi-permanent magnetic material to make, and the line bag adopts forward and reverse direct current to replace the moment powered operation.Produce the forward magnetic flux when forward dc electricity transient flow lambda line bag, magnetize half permanent magnetism iron core with the armature adhesive, normally closed interlock striping bag has a power failure, and the remanent magnetism of iron core continues armature is held; When reverse direct current transient flow lambda line packet generation counter magnetic flux, to offset iron core forward magnetic flux loss of excitation and discharge, normally open contact striping bag has a power failure, thereby reaches the utility model line bag purpose of power saving of need not switching on for a long time.
The beneficial effects of the utility model are, the power saving of need not switching on for a long time of line bag also has quick action, noiselessness.

Embodiment
In the embodiment shown in fig. 1, on inner casing 4, connect main and auxiliary contact 2,3, armature 5, in the shell 9 of packing into together, the upper and lower slip of energy, spring 6 tops are contained on the inner casing 4, and line bag 7 is placed on the spring 6, iron core 8 inserts in line bag 7 holes, with base plate 10 iron core 8 is fastened, and forms contactor.Inner casing 4 drives contact 2,3 to lower slider when armature 5 adhesives, and opposite inner casing 4 drives contact 2,3 and resets.
In operation winding diagram shown in Figure 2, starting doubly-linked button A

2, the forward dc electricity produces the forward magnetic flux through normally closed contact 3 inflow line bags 7, magnetizes half permanent magnetism iron core 8 with armature 5 adhesives, and normally closed interlock 3 disconnects, the outage of line bag, remanent magnetism maintenance work in the iron core 8, normally open contact 3 is connected; Stop doubly-linked button A when pressing
3, A
4, oppositely direct current is through normally open contact 3 inflow line packet generation 7 counter magnetic fluxs, and the forward magnetic flux is cancelled 5 releases of loss of excitation armature in the iron core 8,7 outages of normally open contact 3 striping bags.This contactor line bag need not be switched on for a long time, so very economize on electricity also has advantages such as quick action, noiselessness.
Claims (2)
1. magnetic padlock A.C. contactor, it is made up of shell, inner casing, major-minor contact, line bag, iron core, armature, spring, doubly-linked button etc., it is characterized in that: the semi-permanent magnetic material that adopts unshakable in one's determination is made, and the line bag adopts forward and reverse direct current to replace the moment powered operation.
2. magnetic padlock A.C. contactor according to claim 1 is characterized in that: starting doubly-linked button and stop respectively a to connect normally closed interlock and a normally open contact of doubly-linked button and be electrically connected with DC power supply.
