Abstract
A mechanical electric compound relay includes an input joint, a first relay, a power switch tube and an output joint connected in sequence in series; the compound relay also includes a second relay; the contact points of the second relay are respectively connected with the input joint and the output joint; the power switch tube is taken as a switch to connect through and cut off a circuit in the compound relay and can eliminate a voltaic arc; the first relay plays the role of connecting through when being electrified and isolating action when being cut off; the second relay is connected in parallel with the first relay and the power switch tube connected in series; after the circuit is connected through, the second relay is then connected through to bear a current load; the power switch tube almost has no current load; therefore, the power switch tube almost can not heat.
Description
[technical field]
The present invention relates to the relay of a kind of connection and open circuit, particularly a kind of Mechatronic compound relay.
[background technology]
Relay or title contactor are the circuit devcies that is most widely used at present, play the effect that is communicated with and disconnects in AC-DC Circuit.Alternating current has the alternation characteristic, and the phase electric current is all wanted zero passage weekly, and the natural arc extinguishing effect is arranged, thus use general AC relay mostly, but when the peak that exchanges ripple turn-offed, the electric current maximum can produce discharge arcing phenomenon.
Direct current is continuous, comes disjunction then more to be easy to generate electric arc with switch with mechanical contact, and electric arc is the principal element that influences the relay life-span.
In the prior art, for arc extinguishing, the mechanical contact-type direct current relay all do heavyly and self power consumption bigger, adopt supplementary meanss such as vacuum, inert gas or liquid arc extinguishing, can only play the effect of alleviation, can not fundamentally solve the problem of discharge arcing.
IGBT power tube, MOSFET power tube, NPN power tube and thyristor module etc. are very general as the electronic switch application scenario, relatively typical application is large-scale Switching Power Supply and frequency converter, as Chinese utility model patent 200520036176 disclosed " a kind of combined type direct current relay " is exactly one of them, adopt mechanical relay to connect and form direct current relay in conjunction with auxiliary control circuit again, can eliminate disconnection arcing phenomenon with electronic switch.But all there is internal resistance in all electronic switches, can produce heat when bearing load, need the radiator of configuration bulk and select bigger overheated safety factor for use, obviously will increase manufacturing cost.
[summary of the invention]
The purpose of this invention is to provide the compound direct current relay of a kind of mechanical electronic mode, can be reduced to minimum level to the self-heating of electronic switch, thereby greatly prolong the relay life-span, reduce relay weight, volume and cost.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of Mechatronic compound relay, comprise and be input adapter, first relay, power switch pipe and the out splice going splice that is connected in series successively, it is characterized in that: also comprise second relay, the contact of second relay is connected to input adapter and out splice going splice.
In this programme, power switch pipe is communicated with and open circuit at compound relay as switch, can eliminate electric arc; First relay plays electric connection and outage buffer action; Second relay is with to be first relay and the power switch pipe that are connected in series in parallel, and behind circuit turn-on, second relay conducting is again born current loading, and power switch pipe does not almost have current loading, therefore also just can generate heat hardly.
[description of drawings]
Accompanying drawing is the circuit block diagram of Mechatronic compound relay of the present invention.
[embodiment]
Be described further below in conjunction with the embodiment of the invention and accompanying drawing thereof.
See also embodiment shown in the drawings, a kind of Mechatronic compound relay, comprise: comprise being input adapter 10, first relay 20, power switch pipe 40 and the out splice going splice 50 that is connected in series successively, the contact that also comprises second relay, 30, the second relays 30 is connected to input adapter 10 and out splice going splice 50.
Power switch pipe (40) adopts any in IGBT power tube, MOSFET power tube, the NPN power tube, as the switch of DC circuit.Power switch pipe (40) adopts thyristor module, comprises bidirectional triode thyristor or one-way SCR inverse parallel, then is used as the switch of alternating current circuit.
Control end KZ1, KZ2, the KZ3 of each relay 20,30 and power switch pipe 40 all are connected with correspondent control circuits in the circuit, and these control circuits all are common, repeat no more.
Present embodiment concrete operations order is as follows:
Loading powers on: relay 20 first adhesives, power switch pipe 40 conductings, relay 30 adhesives, circuit debugging.When relay 20 adhesive conductings, circuit is conducting not, and the circuit no current is avoided the excessive meltdown of electric current contact; And when relay 30 adhesive conductings, because the circuit on,, avoid the excessive and arcing meltdown contact problems of electric current so the contact does not have impact.
Following electricity unloading: relay 30 disconnects, and power switch pipe 40 disconnects, and relay 20 disconnects, and circuit disconnects.When relay 30 disconnects, because relay 20 and power switch pipe 40 are in conducting, so relay 30 does not produce arcing when disconnecting; Power switch pipe 40 disconnects subsequently, and entire circuit is disconnected, the circuit no current, and this moment, relay 20 disconnections can not produce the arcing phenomenon too, only played buffer action.
In the said process, power switch pipe 40 is only born whole loads in the very short time of power on loading and electricity unloading down, so radiator can be done very for a short time, even does not consider.
