Abstract

An electrification self-breaking large electric clearance intelligent permanent magnet relay comprises a permanent switching circuit (A), a micro-control circuit (B), an electrification self-breaking triggering circuit (C) and a power supply circuit (D). An electrical contact is immediately and automatically cut after the magnetic relay is electrified so as to ensure that the electrical contact is in a normally open state when being used from the start, thereby being favorable for the safety; the permanent magnet relay has the creative functions, such as no power consumption or no heating of a solenoid coil when working in a stable state, the electric clearance of the contact being larger than 3.2mm, the integration of protective control, and the like. The invention overcomes the technical shortcomings that the electrical contact of the prior permanent magnet relay can not be kept in a normally open state, thereby being not favorable for the safety; the solenoid coil consumes power and emits heat when the prior electromagnetic relay works in the stable state; the contact electrical clearance between the permanent magnet relay and the prior electromagnetic relay is far less than 3.2mm; and the like.

Accompanying drawing 2 is electrical schematic diagrams of the present invention.

Embodiment

Now with accompanying drawing 2 explanations operation principle of the present invention: when enabling, press manual micro switch S1 or go into end 3 inputs one positive level signal to micro-control IC, this positive signal is amplified shaping through micro-control IC and is handled the back to go out end 2 for negative and export pulse electromotive force for positive electric polarity to solenoid m1, m2 to go out end 4, this pulse electromotive force drives permanent-magnetic switching M adhesive, and L and L1 connection and N and N1 connect and power to the load; When closing, press manual micro switch S2 or go into end 1 input one positive level signal to micro-control IC, this positive signal is amplified shaping through micro-control IC and is handled the back to go out end 2 for just and to go out end 4 exporting the pulse electromotive force for negative electric polarity to solenoid m1, m2, this pulse electromotive force drives permanent-magnetic switching M disjunction, stops powering to the load.When this permanent-magnet relay M go into to hold L, when going into to hold N double-pole switch S3 being in closure state in energized, the elementary acquisition voltage signal of coupling transformer H, this is the signal of telecommunication of disjunction permanent-magnetic switching M, this signal of telecommunication is coupled to H level holds 5, goes into end 6 through rectifying and wave-filtering input micro-control IC, to go out to hold 2 for just and to go out end 4 exporting the pulse electromotive force for the electric polarity of bearing to solenoid m1, m2, this pulse electromotive force drives permanent-magnetic switching M disjunction to this positive signal: energising automatic breaking function that Here it is after micro-control IC differentiates the amplification shaping.If during from micro-control IC end 1 input enabling signal, micro-control IC can suppress the input signal of coupling transformer H automatically, thereby do not influence the normal adhesive of permanent-magnetic switching M and disjunction.
