Belong to power start engineering device technique field.
Background technology
The characteristics of asynchronous machine is with its excellent performance and Maintenance free, is widely used in all trades and professions.So
And due in traditional Starting mode, it is AC380 full voltages that when startup, which is added on motor, and motor will accelerate in moment from zero
To rated speed, starting current is caused to reach 5-8 times of rated current of motor, simultaneously because it is larger to start stress, can reduced negative
The service life of equipment is carried, while fatal impact is all constituted to entire network system, circuit, protection equipment.For this purpose, national
Relevant department early have to electric motor starting clearly stipulate that i.e. electric motor starting when network voltage decline no more than 15%.It is adopted by this
There are two the solutions taken：One is to increase distribution capacity, the other is increasing the starting device of limiting motor starting current.
If only increase distribution capacity to start motor, it is economically upper for, it is clear that it is undesirable.For this purpose, people often match
The starting device of standby limiting motor starting current, and it is depressured etc. using Y/ △ conversions, from lotus root decompression, magnetic control modes come current limliting, from
And make motor realize smooth starting, finally allow mechanically and electrically stress minimize.Although these modes can play certain limit
Stream acts on, but does not tackle the problem at its root.
With the continuous improvement that automation requires, use silicon-controlled for the intelligence of main devices, microcontroller core in order to control
