Description
Technical field
The utility model relates to the simple and easy speed regulator of a kind of single-phase greenhouse blower fan, belongs to electrical and electronic technology field.
Background technique
In agricultural production, often need to take a breath to greenhouse by blower fan and regulate temperature, but existing greenhouse blower fan just carries out switch to blower fan, can not carry out speed governing, brings a lot of inconvenience to production.If carry out motor speed-regulating with the existing machine governor in market, cost is higher.Be not very high feature for greenhouse to rotation speed of fan required precision, a kind of simple and easy, greenhouse fan speed regulation device cheaply of invention, is necessary in the prior art.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of single-phase greenhouse blower fan simple and easy speed regulator, as required blower fan has been carried out to speed governing, reached the convenient object of adjusting greenhouse temperature and ventilation.
Technical solutions of the utility model are: the simple and easy speed regulator of a kind of single-phase greenhouse blower fan, comprises power switch 1, blower fan tenminal block 2, blower fan 3, single-pole double-throw switch (SPDT) 4, inductance coil 5, fixed value resistance 6, adjustable resistance 7, bidirectional triode thyristor 8, fixed value resistance 9, electric capacity I 10, electric capacity II 11, described power switch 1 is connected on main circuit power supply, blower fan tenminal block 2 connects respectively power switch 1 and single-pole double-throw switch (SPDT) 4, single-pole double-throw switch (SPDT) 4 connecting to neutral line and inductance coil 5 respectively, inductance coil 5 connects fixed value resistance 6, fixed value resistance 6 connects respectively the first anode of adjustable resistance 7 and bidirectional triode thyristor 8, adjustable resistance 7 connects one end of electric capacity II 11, another terminal connecting zero line of electric capacity II 11, the first anode of bidirectional triode thyristor 8 connects fixed value resistance 9, the second plate connecting to neutral line of bidirectional triode thyristor 8, the control utmost point of bidirectional triode thyristor 8 is connected on the intermediate node of adjustable resistance 7 and electric capacity II 11, fixed value resistance 9 connects one end of electric capacity I 10, another terminal connecting zero line of electric capacity I 10.
