Background technique
Contactor is the common device in low-voltage distribution field, and effect mainly switches on and off electrical load.Conventional
Contactor principle is: after contactor coil is powered, coil current can generate magnetic field, and the magnetic field of generation makes static iron core generate electromagnetism
Suction attracts dynamic iron core, and A.C. contactor point is driven to act, and normally-closed contact disconnects, normally opened contact closure；When the coil is de-energized,
Electromagnetic attraction disappears, and armature discharges under the action of release spring, restores contact, and normally opened contact disconnects, normally-closed contact closure.
Therefore, this principle of contactor results in two kinds of results: first, contactor is a consumer products, i.e. its control terminal is not
It can power off, not only cause active damage year in year out, also cause reactive power consumption；Second, contactor is a Sensitive Apparatus, by
Directly take electricity in major loop in its control terminal, when main circuit power meets with external rolling electricity, contactor is likely to due to under-voltage
It is unexpected that tripping directly result in connected device and have a power failure, shut down.In petrochemical system, in order to solve the problems, such as the rolling electricity of contactor, have
Design special anti-shake electric module can be added, not only increase cost, but also increase volume.
