The controllable silicon is fixed with the bimetal sheet of the thermal relay through insulating materials. The utility model has advantages of simple structure, broad accommodation for the input voltage, overload and overheat protection, matching with the initial line board of the generator and reliable operation.
Description
The utility model relates to the monophase machine electronics and plays guarantor's switch.
At present, monophase machine plays guarantor's switch, adopts the mechanical type contact switch more, and switch contact at work easily sparkles ablatedly, and makes burn-down of electric motor.The noncontacting switch that though existing various electronic components are formed on the existing market, as Chinese patent CN90219229.9 monophase machine electronics contactless starting switch, though solved deficiency in the above-mentioned technology substantially, this switch is long at motor rotation blockage and starting time, overload, when overheated, easily lose its switching function, and burn starting winding and switch element, relatively poor to the adaptability of mains voltage variations, if install radiator additional, then volume of switch increases, and cost up is used inconvenient.
The purpose of this utility model is to provide a kind of above-mentioned weak point of avoiding, and has overload, overtemperature protection, and can regulate input supply voltage and match with the former line plate of motor, easy-to-connect, volume is little, and the monophase machine electronics that cost is low plays guarantor's switch.
For achieving the above object, below structural principle of the present utility model is described.
The utility model comprises box body, voltage regulator, adjuster, controllable silicon; one protector is installed in box body; protector adopts thermal relay; thermal relay one end is connected with voltage regulator secondary winding coil; the other end is connected with the silicon controlled control utmost point; silicon controlled negative electrode, anode are connected in series with starting capacitance, starting winding coil and main winding, are connected with power supply through the voltage regulator primary coil again, and controllable silicon and thermal relay bimetal leaf are fixed by insulating material.
The voltage regulator shunt coil through the adjuster moving plate be connected with the silicon controlled negative electrode, simultaneously the silicon controlled negative electrode is connected with voltage regulator secondary winding coil, thermal relay one end links to each other with voltage regulator secondary winding circle, the other end extremely links to each other with silicon controlled control, the silicon controlled anode is connected in series with starting capacitance, starting winding coil and main winding, is connected with power supply through the voltage regulator primary coil again.
Below in conjunction with accompanying drawing this switch is further described:
Fig. 1, monophase machine electronics rise protects the construction of switch schematic diagram.
Fig. 2, monophase machine electronics rise protects the construction of switch end view.
Fig. 3, controller structure principle schematic.
Fig. 4, thermal relay structural representation.

The utility model course of work is as follows:
Behind power connection, there is electric current to pass through among the voltage regulator primary coil L3, while induction voltage regulator secondary coil L4, voltage regulator secondary coil L4 obtains induced current, when induced current reaches the best boundary current value of the required triggering of controllable silicon, switch closure, electric current is by electric motor starting winding coil L2, electric motor starting.Regulate adjustable iron core screw, adjustable iron core is moved up and down, then iron circuit and air magnetic circuit ratio change, make the size variation of magnetic resistance reach the turn ratio value that changes voltage regulator primary winding coil L3 and the secondary level of voltage regulator coil L4, realize the stepless contactless speed governing of switch, reach the effect of automatic switch.Connect a shunting winding coil L5 in voltage regulator primary winding coil L3 portion, regulate adjuster moving plate and shunting winding coil L5 position, can change voltage regulator primary winding coil L3 two ends supply voltage ratio and electric motor starting current ratio, regulate adjuster moving plate 10 and make it to slide to the empty end of revolving of adjuster shunt coil 5, then supply voltage and starting current increase thereupon, otherwise then reduce.Rotating speed during electric motor starting and adjuster moving plate 10 position synchronous with adjuster shunt coil L5 of living in.When motor is obstructed stall or overload; electric current by controllable silicon 15 increases; the heat that controllable silicon 15 produces passes to thermal relay 14 rapidly; when reaching the operating temperature of thermal relay 14, thermal relay 14 action normally-closed contacts are opened the control utmost point G dead electricity of controllable silicon 15; controllable silicon 15 turn-offs; this moment, controllable silicon 15 no currents passed through, and starting winding coil L2 dead electricity is protected controllable silicon 15 and starting winding coil L2.To adopt the turn ratio of voltage regulator primary coil L3 and voltage regulator secondary coil L4 be 1: 15～30 in order this is risen protect switch to reach the best protection state, and the line of voltage regulator shunt coil L5 and voltage regulator primary coil L3 is directly than being 1: 2～2.5.
Compared with prior art, the utility model has following advantage:
When 1, long in motor rotation blockage and starting time, switch element and starting winding are got To protection, and make it can participate at short notice restarting.
2, wide to input supply voltage accommodation.
3, volume is little, and cost is low, and is easy for installation.
4, prolong the service life of motor.
