Abstract
The utility model relates to an energy-saving magnetic switch belonging to electrical equipment. A locking mechanism is arranged in the casing of the switch. A jack clip and a jack draw rod connected with an electrical magnet matched with a coil are connected. A moving contact is arranged on the draw rod on which a spring and a draw rod block are arranged. A position corresponding to the moving contact is provided with a static contact. Electrical energy can be economized by the utility model by more than 95%. The service life of the switch can be extended.
Description
The utility model is a kind of economize on electricity magnetic switch, belongs to power equipment.
At present, employed electromagnetic force switch in industrial production all is to make the magnet spool of switch pass to electric current, makes electrical contact with the gravitation that electromagnet produced, under certain pressure and the contact conducting.For the operation of keeping switch is used, when switch is worked, must keep often energising, thereby as long as switch itself is in running order, will consume electric power, because solenoid is to belong to inductive parts, thereby generally power factor has only about 0.35～0.5, so the efficient of electrical network is decreased.Simultaneously,, periodically strong and weak the variation arranged,, thereby cause the contact contact to wear and tear comparatively fast, shortened the life-span of switch so electromagnet also change with magnetic field is strong and weak the pressure of the contact of switch owing to exchange the magnetic force produced.
The purpose of this utility model provides a kind of saving electric power, prolongs the switch economize on electricity magnetic switch in useful life.
The utility model is achieved through the following technical measures: Fig. 1 is the utility model structural representation.When actuating coil 16 fed electric current, electromagnet 18 sucked and descends, and presses pull bar shelves 6 by depression bar 17, pull bar 1 is descended, when dropping to certain position, collide with very heavy card 8, because very heavy card 8 tops are slopes, movable axis 14 is arranged at the bottom, and when pull bar 1 descended, very heavy card 8 was swung to the right side, when pull bar 1 continues to descend, when pull bar shelves 7 passed through the flat bayonet socket of very heavy card 13 places, because the effect of spring 12 pulling force, very heavy card 8 blocked pull bar shelves 7.After coil 16 outages this moment, though electromagnet does not have magnetic force, pull bar 1 still can not reset.Moving contact 3 makes switch in running order because the pressure of spring 2 is firmly pushed down on the fixed contact 5.But itself cuts off the power supply switch, and consumed power not reaches the purpose of saves energy.This moment, contact was static, and the no periodic vibration reduces the contact wearing and tearing, the useful life that can improve switch.
When coil 11 energisings, electromagnet 10 is inhaled action, by very heavy pull bar 9, very heavy card 8 is drawn back, and pull bar shelves 7, pull bar 1, moving contact 3 are subjected to the elastic force effect of spring 4 and reset.Switch is in off-position, and this moment, coil 11 can cut off the power supply.
If under must working condition requirement, decompression falls on the circuit of lock, must install a no-voltage release additional.Fig. 2 is the structural representation of release.G is a base plate among the figure, and 24 is capacitor, and 23 is relay, and 25 is rectifier diode, and 26 is regulating resistor.
Fig. 3 dotted portion is the release circuit theory diagrams.A, B are supply voltage among the figure, 26 is regulating resistor, 23 is relay, when coil 23 is connected with resistance 26, after the energising, the actuating of relay is when contact a and b connection, capacitor 24 is by drag flow diode 25, be subjected to charged with direct current, when external circuit had a power failure, relay contact resetted, a, b point disconnects, b, c point is connected, and the coil 11 that stops among c point and Fig. 1 joins at this moment, and capacitor 24 stored electric energy can make electromagnet 10 adhesives, spur very heavy card 8 and make just in working order switch breaking, thereby reach the purpose of no-voltage trip breaking.
The utlity model has the saving electric energy, the distinguishing feature that increases the service life.
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the schematic diagram of the utility model release.
Fig. 3 is the schematic diagram of the utility model release.
Fig. 4 is the utility model coil 11,16 circuit theory diagrams.
Fig. 1～4th, the utility model specific embodiment.Pull bar 1 is housed in switch case, spring 2 is housed on the pull bar 1, moving contact 3 is equipped with in spring 2 bottoms, moving contact 3 bottom shock mounts 4, and spring 4 bottoms contact with the switch case standing part.Fixed contact 5 is housed in the switch case of moving contact 3 relevant positions, is processed with pull bar shelves 6,7 in the bottom of pull bar 1, extension spring 12 1 ends are connected with very heavy card 8, and extension spring 12 other ends are fixed on the switch case.Very heavy card 8 is connected on the switch case by live axle 14.Very heavy card 8 is connected with very heavy pull bar 9, and very heavy pull bar 9 is connected with electromagnet 10, and coil 11 cooperates with electromagnet 10, and coil 11 is contained in deciding in the iron 27 of switch case.Deciding in the iron 19 on coil 16 is contained in the switch case, depression bar 17 pull bars 21 are contained on the switch case by axle 20.Extension spring 22 1 ends are connected with pull bar 21, and the other end is fixed on the switch case.The utility model also must be equipped with no-voltage release under necessary operating mode, and as dotted portion in Fig. 3, electric capacity 24 is connected 23 with relay, and relay 23 is connected with rectifier diode 25, and regulating resistor 26 1 ends are connected with rectifier diode 25, another relay termination 23.Relay 23 is connected with coil 11.
The utility model can economize on electricity more than 95% during than the power consumption of the magnetic switch that uses at present when ignoring starting.And conservation improves the useful life of switch.
