Abstract
This device relate to a kind of on ac power supply line employed highly efficient power saving electromagnetic mechanism, realization is kept adhesive to the little current DC of the electromagnetic clutch mechanism of a joint alternating electromagnetic switch, tractive electromagnet class is excitatory, optimize operation, the relay-type electromagnetic mechanism of energy-conservation, practical, good reliability.
Description
This device relates to employed highly efficient power saving electromagnetic mechanism on a kind of ac power supply line.
The operation of the extensive use of AC electromagnetic mechanism and the outmoded AC electromagnetic mechanism of poor efficiency and version have shown outstanding contradiction in the prior art.AC electromagnetic mechanism exists magnetic hysteresis loss, eddy current loss.And, have to make it at the bigger supplementary load loss that move under the attract current and cause of keeping in order to obtain enough big starting torque.So, showed the diseconomy of widely used AC electromagnetic mechanism operation.Direct solenoid mechanism does not have shortcoming as above.Nowadays, it is inexpensive that rectifying device has become, and function admirable is reliable, uses direct current excitatory economical and practical, and this device adopts the high-power starting of pulsating direct current, and the direct current small-power is kept adhesive, and the economize on electricity index is greater than 80 percent.
This device is by movable core M
1, secured core M
2, magnetizing coil W forms electromagnet S, by diode D
1, D
2, D
3, D
4The bridge rectifier power supply A that forms is by transformer BV, diode D
5, D
6, D
7, D
8The bridge rectifier power supply B that forms is by normally closed sliding contact J
1, often open sliding contact J
2, fixed contact C
1, C
2, C
3, C
4, the additional changeover switch C that forms of insulated connecting rod H, collision block F.Entire mechanism is made up of above three parts.
The course of work is to exchange the 220/380V power supply to give rectifier A by K switch O, and the pulsating direct current electric current after the rectification is set out through the normally-closed contact C of additional changeover switch C by positive pole
1, C
2, start button K, stop button O, magnetizing coil W form the loop to the negative pole of rectifier A.This moment, bigger starting exciting curent flow through coil W, produced bigger magnetic potential, made iron core M
1Adhesive rapidly.In attracting process, with iron core M
1The collision block F that links to each other makes the insulated connecting rod H on the additional changeover switch C drive normally opened contact J
2With normally-closed contact J
1Stressed priority action displacement promptly on the thronely moves past contact C in the journey
3, C
4After connecting in advance, contact C
1, C
2Disconnect again.Because contact C
3, C
4Closure makes via the little electric current of forward low-voltage direct after transformer BV step-down, the rectifier B rectification by anti-adverse current breakdown diode D
9, contact C
3, C
4, stop button O, magnetizing coil W form the loop to the negative pole of rectifier B, to guarantee that starting current is by normally-closed contact J
1Disconnect the back magnetizing coil and under the little electric current low-power consumption of low-voltage direct condition, keep the iron core adhesive.Operation stop button O can make magnetizing coil stop power supply, iron core M
1Discharged rapidly and returned.
This installs the AC electromagnetic mechanism that above-mentioned mode of operation is applicable to fully that also existing technical field is used, and can receive identical reliability, economy, practicality and energy-efficient optimization synthesis index.
Claims (3)
1, for adopting two kinds of DC power supply that electromagnet is carried out the calutron of time sharing power supply, this device has by magnetizing coil W, movable core M
1, secured core M
2Form electromagnet S, by diode D
1, D
2, D
3, D
4Form bridge rectifier A, by transformer BV, diode D
5, D
