Description
Technical field
The utility model is related to a kind of controller, specifically a kind of contactless controller.
Background technology
The conventional control mode of AC crane speed regulation cuts resistance control, stator voltage controlling debugging control, frequency control control
System etc., has used many A.C. contactors in these electric wirings.The operation principle of A.C. contactor：When the coil is energized, it is quiet
Iron core produces electromagnetic attraction, and by dynamic iron core adhesive, because contact system is linked with dynamic iron core, therefore dynamic iron core drives main touch
Point closure, so as to switch on power；When the coil is de-energized, suction disappears, and dynamic iron core linkage part is by the reaction force of spring
Separation, disconnects main contact, cuts off the electricity supply.Had the following disadvantages using the circuit of A.C. contactor：
First, cost is higher：Large Copacity A.C. contactor separate unit price is general higher, and whole electrical system cost is high.
2nd, contactor service life is short：Because of the general frequent break-make of A.C. contactor in crane circuit, therefore A.C. contactor
Service life is shorter.
3rd, potential safety hazard：The frequent adhesive of AC contactor main contact disconnects, when the loss of main contact conducting medium is larger,
Main noddle on contactor may adhesion, generation potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of contactless controller, with asking for solving to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：
A kind of contactless controller, including power module, trigger module and thyristor module, power module are whole control
Device provides power supply, and the input of power module connects AV220V power supplys, and the output end connection of power module is trigger module, institute
State to be provided with power module on indicator lamp and auxiliary output, the trigger module and be provided with control contact, for controlling triggering
The break-make of module, the output end connection of trigger module is several thyristor modules.
It is used as further program of the utility model：The thyristor module controls the break-make of major loop.
It is used as the utility model further scheme：Several described thyristor modules are connected by the way of series connection.
Compared with prior art, the beneficial effects of the utility model are：The utility model is replaced using contactless controller
For the rotating in crane circuit, the A.C. contactors such as resistance are cut, this contactless controller is using the brilliant lock of control circuit triggering
Pipe turns on, disconnects realizing the function of major loop break-make, employs photoelectric coupling and Power Electronic Technique, with no-spark, resists
Interference performance is strong, long lifespan the advantages of, be particularly suitable for acting frequently and electrical control system of crane that working environment is severe.
Simple using the circuit structure of the controller, dependable performance, electrical system overall cost is greatly reduced.
Brief description of the drawings
Fig. 1 is the theory structure schematic diagram of contactless controller.
Fig. 2 is the circuit diagram of contactless controller.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1~2, the utility model embodiment, a kind of contactless controller, including power module, trigger mode
Block and thyristor module, power module provide power supply, the input connection AV220V power supplys of power module, electricity for whole controller
The output end connection of source module is trigger module, and indicator lamp is provided with the power module and auxiliary is exported, indicator lamp can
Control contact is provided with the break-make situation of power module, the trigger module to show, for controlling the break-make of trigger module,
The output end connection of trigger module is several thyristor modules, and several thyristor modules are connected by the way of series connection,
When thyristor module bears reverse anode voltage, no matter which kind of voltage gate pole bears, thyristor module is all in reverse blocking shape
State, when thyristor module bears positive anode voltage, only in the case where gate pole bears forward voltage, thyristor module is just turned on,
At this moment IGCT is in forward conduction state, here it is the lock properties of flow of IGCT, you can control characteristic, thyristor module is in conducting
In the case of, as long as there is certain positive anode voltage, no matter gate voltage, IGCT is held on, i.e. thyristor module
After conducting, gate pole is ineffective, and gate pole only plays trigger action, thyristor module in the case of conducting, when main circuit voltage (or electricity
Stream) when being reduced to close to zero, thyristor module shut-off, so as to realize the function of major loop break-make.
The utility model is substituted rotating in crane circuit using contactless controller, cuts the ac contactors such as resistance
Device, this contactless controller realizes the function of major loop break-make using control circuit triggering turn on thyristors, disconnection, employs
Photoelectric coupling and Power Electronic Technique, have the advantages that no-spark, strong antijamming capability, long lifespan, are particularly suitable for action frequency
The severe electrical control system of crane of numerous and working environment.Simple, the dependable performance using the circuit structure of the controller, electrically
System overall cost is greatly reduced.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
