Abstract
The invention discloses a full-electronic solid-state contactor, which comprises a solid-state contactor normally closed auxiliary contact, a rectification filter circuit, an optocoupler triggering module, a solid-state contactor normally open auxiliary contact and an RC absorption circuit. The full-electronic contactor provided by the invention can be used as a double-system switching device. When a main loop is not switched on, a normally closed low-current solid-state contactor is in an on state, while other switching points are in an off state. When a circuit is switched on, the contactor originally in the on state is switched off, and the original off state of the switching points is changed into the on state. In operations, the main loop is switched on and off by the small auxiliary contacts; simultaneously, a delicately-shaped plastic housing convenient to wire is designed for the needs of an automation device; and the full-electronic solid-state contactor avoids model temperature rise, is ageing-resistant and anticorrosive and has ultralong service life which is triple that of the conventional contactor.
Description
Technical field
The present invention relates to a kind of solid-state contactor; be particularly related in a kind of protection or various manufacturing machine automatic control circuit that is mainly used in electric equipment; as the control motor; also can be used for controlling other electrical load, as the solid-state contactor of full electronic of electric equipments such as electric heater, illumination, electric welding machine, capacitor, shop equipment, machine-tool and various kinds electric power unit.
Background technology
In automatic field, some relays can not satisfy the needs of high automation gradually at present, and relay only is applied in control loop and the protection loop, as a switch of often opening, just realizes the function of crawl; The contact capacity of relay is smaller simultaneously, can't satisfy the control needs of equipment, and we design the contactor of a full electronic at this phenomenon, and contactor cooperates relay to use, to realize chain control.
Summary of the invention
At prior art problems; the present invention proposes the solid-state contactor of a kind of full electronic, and it combines the advantage of relay and contactor, can realize controlling connection or cutting off forceful electric power with light current; but also have the low-voltage release guard, play the effect of security insurance.It is big to control capacity simultaneously, can be used for the big equipment of frequent starting electric current, also can be used for the automatic operation of far distance controlled power consumption equipment and stops.
To achieve the object of the present invention, full electronic contactor of the present invention comprises that solid-state contactor normally closed auxiliary contact, current rectifying and wave filtering circuit, optocoupler trigger module, solid-state relay are often driven auxiliary contact and RC absorbs circuit.
During work, when the main contacts of contactor was closed, the solid-state contactor normally-closed contact of little electric current disconnected, and major loop is not worked, and presses auxiliary contact and often drives solid-state relay, often opens the auxiliary contact adhesive.Major loop is communicated with control line by auxiliary contact.The solid-state contactor of all-electronin of the present invention is exactly on the basis of crawl, realizes the through and off of load by auxiliary contact.When switch closes a floodgate, pair of contact is arranged with closure or open in the auxiliary contact, this access control loop, contact just can be reflected the current state in loop synchronously.If insert the protection loop, can be used as the precondition of loop protection action.
Full electronic contactor of the present invention can be used as a kind of double-standard switching device, and when the major loop access failure, the normally closed solid-state contactor of little electric current is in conducting state, and other switching point then is in off-state.When circuit was connected, the former contactor that is in closure state disconnected, and the former off-state switch that is in then changes conducting state into.When operating, utilize slight auxiliary contact to remove to switch on and off major loop; Simultaneously, designed a profile exquisiteness at the needs of automation equipment, easy-to-connect mould shell, model does not have temperature rise, and ageing-resistant, and is anticorrosive, overlength useful life is traditional three times.
Description of drawings
By the detailed description below in conjunction with accompanying drawing, aforesaid purpose, the feature and advantage with other of the present invention will become apparent.Wherein:
Figure 1 shows that the structural representation of the solid-state contactor of all-electronin of the present invention;
Figure 2 shows that the circuit theory diagrams of the solid-state contactor of all-electronin of the present invention.
Embodiment
As shown in Figure 1, the solid-state contactor of all-electronin of the present invention comprises that solid-state contactor normally closed auxiliary contact, current rectifying and wave filtering circuit, optocoupler trigger module, solid-state relay are often driven auxiliary contact and RC absorbs circuit, and wherein said solid-state contactor normally closed auxiliary contact is connected in before the current rectifying and wave filtering circuit; Solid-state relay often leaves auxiliary contact and is connected between current rectifying and wave filtering circuit and the optocoupler trigger module.
Shown in the circuit theory diagrams of Fig. 2, during work, when No. 1, input, No. 2 energisings, by the D1 rectification, solid-state contactor J1 normally closed auxiliary contact gets electric automatic disconnection earlier, and promptly S1 disconnects.S2 connects load power source as a normal open switch, when S1 gets electric disconnection, the auxiliary contact adhesive often left by solid-state relay, the control end electric current is through step-down rectifier filtering, and LED lights, and control loop is connected, after step-down, make circuit voltage reach the trouble free service voltage range of optocoupler, optocoupler triggers to the controllable silicon gate pole provides trigger current, and relay gets electric work.In the course of the work, mainly, realize the function of the through and off of full electronic by having the relay of often opening function and the contactor interlocking that has normally closed function.
During work, when main contacts was closed, the solid-state contactor normally closed auxiliary contact of little electric current disconnected, and major loop is not worked, and presses auxiliary contact and often drives solid-state relay, often opens the auxiliary contact adhesive.Major loop is communicated with control line by auxiliary contact.The solid-state contactor of all-electronin of the present invention is exactly on the basis of crawl, realizes the through and off of load by auxiliary contact.When switch closes a floodgate, pair of contact is arranged with closure or open in the auxiliary contact, this access control loop, contact just can be reflected the current state in loop synchronously.If insert the protection loop, can be used as the precondition of loop protection action.
In addition, the solid-state contactor of all-electronin of the present invention also is provided with LED and shows parts, shows input state, and power supply and operating state come into plain view and can effectively prevent the misoperation of protection, guarantee the safety in loop.
The useful life of the solid-state contactor of all-electronin of the present invention is very high, can high frequencies of operation, be generally millions of mechanical endurance to 10,000,000 times, and electric life generally then be hundreds thousand of inferior, properties of product are reliable and stable; Noiselessness, nuisanceless, the ON/OFF switch speed is fast, the spark problems of no mechanical switch; Operation is quiet, and noiselessness is not influenced by dust, greasy dirt; And the control cable easy anti-finger of pegging graft touches Safety Design, need not annex.
The present invention is not limited to described embodiment, and those skilled in the art still can do some corrections or change, so the scope of the present invention is as the criterion with claims restricted portion not breaking away from spirit of the present invention promptly openly in the scope.
