Abstract
The invention relates to a magnetic synchronous conversion electromagnetic device used in the field of low-voltage electrical appliances such as contactors, electromagnets and electromagnetic valves, in particular to a magnetic synchronous converter, which is provided with no independent coil and a static iron core and is arranged in a coil framework; a conversion air gap hole is processed on a static iron core of the electromagnetic device near the synchronizer. The principle that the same polarity is mutually repulsive and the static iron core simulates air gap leakage magnetic attraction is utilized to complete the synchronous conversion from the starting of the electromagnetic device to the low-voltage direct current holding, thereby achieving the purposes of noise reduction and electricity saving.
Description
The invention belongs to the energy-saving magnetic synchrotrans electromagnetic device that uses in the low-voltage electrical apparatus fields such as contactor, electromagnet, electromagnetically operated valve.
The power-saving technique of low-voltage electrical apparatuses such as contactor, electromagnet, electromagnetically operated valve mainly is to adopt to make calutron be transformed into the mode of low-voltage direct sticking from full voltage starting." magnetic-synchro conversion electricity-economizing coil " that Chinese patent application number provides for the application for a patent for invention of 92104514.X is to have used a kind of tongue magnetic delay relay, this relay is to be made of the conversion hyoplastron that permeability magnetic material is made, and is installed in the air gap place of electromagnetic system iron core.Utilize the unshakable in one's determination closed front and back of electromagnetic system, the strong and weak principle that changes in its magnetic field, air gap place is repelled, is attracted to change hyoplastron, finishing the economize on electricity conversion.Because this energy-saving coil utilizes the air gap work of magnetic system iron core, and the manufacturing process of air gap is complicated, and precision is difficult for guaranteeing.Change hyoplastron in addition and fix by an axle, when coil installed to unshakable in one's determination going up, the contact-making surface after conversion hyoplastron and the adhesive unshakable in one's determination was less, had influenced the reliability of energy-saving coil work.
The objective of the invention is, be a kind of simple in structure, easily manufactured, the switching motion that solves that deficiency of the prior art designs magnetic synchrotrans electromagnetic device accurately and reliably.
Calutron of the present invention is made up of iron core, coil, magnetic-synchro transducer and current limliting dropping equipment etc.The scheme in conversion air gap hole is processed in employing on the iron core that calutron installs coil, designed a kind of energy-saving coil that the magnetic-synchro transducer is housed.Said magnetic-synchro transducer (hereinafter to be referred as synchronizer) is the moving iron of being made by permeability magnetic material of conversion, links mutually with fixed head by the conversion frame, and compositions such as normally-closed contact are housed on conversion frame and fixed head.Do not have independently coil and fixed core, be installed in the winding of coil.The moving iron retractable in the coil rack hole of conversion is by the permanent magnet location.Install at calutron on the fixed core of coil, near the moving iron of the conversion of synchronizer, be processed with conversion air gap hole.Install to when the coil that has synchronizer on the fixed core of calutron, after the energized, before the magnetic system closure unshakable in one's determination, because moving iron of the conversion of synchronizer and magnetic system fixed core be in same coil windings, its polarity is identical, and is mutually exclusive.Under the effect of repulsive force and permanent magnet suction, the moving iron of conversion is failure to actuate, and compresses normally-closed contact.After the closure unshakable in one's determination of magnetic system, repulsive force disappears, and place, conversion unshakable in one's determination this moment air gap hole is equivalent to simulate air gap, and magnetic resistance is bigger, and leakage field is stronger.The moving iron of the conversion of synchronizer is positioned near the conversion air gap hole, under stray field attracts, overcomes the permanent magnet attraction, be attracted to the fixed core of magnetic system, disconnect normally-closed contact, the current limliting decompression device is devoted oneself to work, make calutron be transformed into the running status of low-voltage direct sticking by startup.
The direction in conversion air gap hole is parallel to the moving iron of conversion on the calutron iron core of the present invention, also can be perpendicular to the moving iron of conversion.The quantity in hole can be processed one or more as required; It is circular or microscler etc. that the shape in hole can be.Can adjust operating characteristic such as the economize on electricity conversion effect of calutron and rate of release with shape, quantity and the size in conversion air gap hole.The conversion frame of synchronizer and fixed head are by the non-magnet material manufacturing.Owing to used the conversion frame, so the degree of freedom of the moving iron of conversion increases, also increase with contact-making surface after the calutron adhesive unshakable in one's determination, adhesive is more firm, makes switching motion more accurately and reliably.
The iron core of this calutron adopts low permeability magnetic material manufacturings such as cast steel, cast iron, all belongs to initiative at home and abroad.
Below in conjunction with description of drawings one embodiment of the present of invention.
Accompanying drawing 1 is an electrical schematic diagram of the present invention: D1～D4 is a rectifier diode among the figure; JC is the electromagnetic system coil; R is a discharge resistance; C is the current limliting decompression capacitor; CSJ is a normally-closed contact.
Accompanying drawing 2 is a structural representation of the present invention: (1) is the calutron fixed core among the figure; (2) be coil rack; (3) be axle; (4) be the moving iron of conversion; (5) be the conversion frame; (6) be permanent magnet; (7) be coil windings; (8) be normally-closed contact; (9) be fixed head; (10) be axle; (11) be conversion air gap hole; (12) moving unshakable in one's determination for calutron.
Among the figure, the conversion of synchronizer is moved iron (4) and is installed in simultaneously in the coil windings (7) with calutron fixed core (1), and its upper end is positioned near the conversion air gap hole (11); The moving iron (4) of conversion is by conversion frame (5) and axle (3) (10) and fixed head (9) hinge joint; Normal contact (8) is installed in respectively on conversion frame (5) and the fixed head (9), attracts the moving iron (4) of conversion to compress by permanent magnet (6); Electronic devices and components in the accompanying drawing 1 all are contained in the outer coil rack (2) of coil windings (7).After energized, before the calutron closure unshakable in one's determination, because calutron fixed core (1) moves iron (4) in same coil windings (7) with the synchronizer conversion, end polarity is identical, the two is mutually exclusive, and the moving iron (4) of conversion is compressed normally-closed contact (8) by the effect of repulsive force.When calutron unshakable in one's determination closed fully, repulsive force disappears, at this moment, it is bigger that magnetic resistance is located in conversion air gap hole (11), leakage field obviously strengthens, and will change moving iron (4) and inhale to fixed core (1), opens normally-closed contact (8) simultaneously, capacitor C drops into the current limliting step-down, has finished by the conversion that starts to straightening stream sticking.When calutron is out of service, coil blackout, the moving iron (4) of conversion resets under the attraction of permanent magnet (6), prepares for start next time.
Calutron of the present invention may be used in contactor, electromagnet, electromagnetically operated valve and other low-voltage electrical apparatus.It is accurate to have the economize on electricity conversion synchronization, compact conformation, make, adjust simple and convenient, reliable in action, characteristics such as noise and electric save is respond well.Can transform operating equipment, and it is supporting to can be manufacturer.
