Description
Technical field
The utility model relates to a kind of switchgear, relates in particular to a kind of electromagnetic switch that is used for switching circuit.
Background technology
Electromagnetic switch of the prior art generally is directly to drive the moving contact motion by electromagnetic assembly, and moving contact is contacted with fixed contact.As the applicant's patent No. formerly is the ZL200620047256.9 utility model patent, its notification number is CN200962407, the day for announcing is on October 17th, 2007, a kind of electromagnetic switch is disclosed, comprise electromagnetic assembly and contact assembly, electromagnetic assembly comprises spring contact 5, contact chip 6, armature 7, contact pilotage 8, yoke 17, coil rack 18, coil 19, iron core 20, short-circuited conducting sleeve 21, and an end and the spring contact 5 of coil 19 join, and the other end and contact chip 6 join; Contact assembly comprises action contact frame 10, moving contact 11, moving contact 12, moving contact stage clip 13, fixed contact 14, fixed contact 15, fixed contact 14 is fixed in the base 16, armature 7 places an end on the yoke 17 to be inserted into the hole of action contact frame 10, the other end places spring contact 5 times, under the active force of reseting pressuring spring 9, armature 7 is upturned, and spring contact 5 and contact chip 6 are separated, and keeping a fixed range, same moving contact 11 also separates and keeps a fixed range with fixed contact 15.This electromagnetic switch armature 7 tops are provided with conducting button (green button) 2, and the top of action contact frame 10 is provided with cut-off push button (red button) 1, and conducting button 2 and cut-off push button 1 all are in the switch topmost position under the effect of stage clip 3.Described spring contact can be made up of contact and stage clip, also can adopt the spring contact of one.When pressing conducting button (green button) 2; armature 7 is in the process of down moving with conducting button 2; spring contact 5 contacted with contact chip 6 before this; coil 19 forms the loop; armature 7 continues down to move with conducting button 2; but armature 7 can not contact iron core 20 all the time but maintain a certain distance in whole process; this moment, moving contact 11 also maintained a certain distance with fixed contact 15; switch does not have conducting; when voltage reaches the value of under-voltage protection defined; the automatic adhesive armature 7 in magnetic field that coil 19 produces, thus moving contact 11 and fixed contact 15 are connected.Opposite when if voltage does not reach the value of defined, the magnetic force that coil 19 produces can not be automatically with armature 7 adhesives, in addition under switch is in attracting state, when voltage step-down during in under-voltage protection voltage, because of the not enough switch of magnetic force also can automatic disconnection.When switch is in conducting state, pressing the disconnection button presses (red button) 1 urgent action contact frame 10 to move down, force moving contact 11 to separate, under the situation of internal structure inefficacy (as spring malfunctioning or sound point burn), press this button and can make the mandatory disconnection of switch simultaneously with fixed contact 15.Such scheme is directly to drive the contact assembly action by electromagnetic assembly, when the needs contact circulates big electric current, then will increase the contact force between the contact assembly, promptly will increase the suction of electromagnetic assembly.But after increasing the suction of contact assembly, electromagnetic assembly just can disconnect the electromagnetic switch insufficient sensitivity when being subjected to current fluctuation greatly.In addition, electromagnetic assembly is received the influence of current fluctuation, makes that the contact between the contact assembly can't be in stable state all the time, influences the circulation of electric current, also causes easily to take place between the contact assembly to wear out, and influences electric property.
