Background technique
Contactor broadly refers to flow through current induced magnetic field using coil in industry, makes contact closure, to reach control
The electric appliance of load.Starter refers to the contactor with control.It is well known that the contactor in reversible magnetic starter is in voltage
3300V, 1140V, 660V, 380V grade, purposes is than wide.Existing magnetic starter is that have contactor ontology stand alone type,
Intermediate relay, intrinsic safety plug-in unit, the associated components such as magnetic protector composition, and the contactor in traditional magnetic starter is general
It is electromagnet band three-phase (a) vacuum tube, although modular contactor is that three electricity keep electromagnet (hereinafter referred to as electromagnetism
Iron), three vacuum tubes of band respectively, but generally there are three reaction spring, In for the electromagnet of existing modular contactor at present
When out of power, pulling force separates vacuum tube enough and main circuit disconnects.Common electromagnet counter-force spring is all in the outer of electromagnet
Face.The object of one insulation in interval of electromagnet and vacuum tube, the release and actuation of electromagnet drive the opening and closing of vacuum tube.Such as
Fruit reaction spring in the outside of electromagnet, due to module outline border close it is grand after, when locking vacuum tube and electromagnet, fine tuning contactor is opened
Away from the excess of stroke, it is easy to rub the conductive tissue of electromagnet and vacuum tube mutually and touch, electromagnetism ferromagnetic cylinder electrification is caused to jeopardize personal peace
Entirely.Therefore existing magnetic starter has volume big, and route is more and many and diverse, and fault point is difficult to check more, and maintenance is inconvenient, more
It is cumbersome and the defects of not can guarantee personal safety to change component.
Existing magnetic starter, such as the applicant's Patent No. disclosed on May 18th, 2016
A kind of modular vacuum magnetic starter of CN201410380397.1, the innovation and creation use modular contactor i.e. three electricity
