Description
Technical field
The present invention relates to the electrical network field, especially a kind of heavy DC switch arc-control device circuit.
Background technology
The basic reason that produces electric arc is to contain the electronics that can be dissociated in a large number in device for switching contact itself and the contact medium on every side, when between the contact of disjunction, there is enough large applied voltage, and circuital current is when also reaching your pupil's arc current, will strongly dissociate and forms electric arc.
So, need a kind of new technical scheme to address the above problem.
Summary of the invention
The objective of the invention is the deficiency for the prior art existence, a kind of heavy DC switch arc-control device circuit is provided.
For achieving the above object, heavy DC switch arc-control device circuit of the present invention can adopt following technical scheme:
A kind of heavy DC switch arc-control device circuit comprises the D.C. contactor that load, the fly-wheel diode with the load parallel connection, coil are connected with load and main contact is in parallel with arc-control device; Described arc-control device is provided with relay and is parallel to the capacitance group at relay normally-closed contact two ends.
Compare with background technology, heavy DC switch arc-control device circuit of the present invention can carry out arc quenching protection, and its operation principle is: relay coil gets electric, and its normally-closed contact disconnects first, and is closed after normal the battle; Simultaneously, the contactor coil dead electricity, contactor often leaves main contact and disconnects, because the electrical time constant of contactor coil is much larger than the electrical time constant of relay coil, and the voltage releasing value is lower, therefore, the normally opened contact of relay can be closed before the main contact disconnection often left by contactor, capacitance group is parallel to contactor often opens the main contact two ends, the voltage of contactor often being left the main contact two ends plays clamping action, make contactor often open main contact and under lower voltage, disconnect, thereby reduce the generation of electric arc.
Preferably, described arc-control device also comprises the first metal-oxide-semiconductor and the second metal-oxide-semiconductor, thereby the G electrode potential of the second metal-oxide-semiconductor drags down relay and can't get electric behind described the first energy storage resistance saturation conduction.
Preferably, described arc-control device also comprises the 6th resistance of connecting with the relay normally-closed contact, and the 6th resistance is in order to discharge capacitance group.
Preferably, also comprise the control power supply, described arc-control device also comprises control switch, the first diode, the 3rd diode, the second resistance, the 4th voltage stabilizing didoe, and described control power supply drives the first metal-oxide-semiconductor saturation conduction by control switch, the first diode, the 3rd diode, the second resistance, the 4th voltage stabilizing didoe.
