Accompanying drawing explanation
Fig. 1 is electromagnetic type power-off restoration switch structure diagram.
Fig. 2 is electromagnetic type power-off restoration switch scheme of installation.
Embodiment
1 to 2 pair of the specific embodiment of the present invention is described further by reference to the accompanying drawings:
A kind of electromagnetic type power-off restoration switch, comprises solenoid, switch lever 2.Switch lever 2 is insulating magnet, and one end of switch lever 2 is connected with back-moving spring 10, and the other end is provided with conduction stock 11, and conduction stock is provided with the first moving contact 7 ', the second moving contact 8 ' and the 3rd moving contact 9 '.The fulcrum of switch lever 2 is fixed with support bar 12, the top of support bar 12 is connected with switch key 1, and switch key 1 is connected on switch lever 2 by connecting rod 14.Back-moving spring 10, support bar 12 are all fixed on base 13.
The line outlet on solenoid top is provided with the first fixed contact 7, first fixed contact 7 and is arranged on immediately below the first moving contact 7 ', and the line outlet of solenoid bottom connects zero line terminals 5 ' through diode 4.Be provided with the second fixed contact 8, second fixed contact 8 immediately below second moving contact 8 ' and connect hot terminal 6, be provided with the 3rd fixed contact the 9, three fixed contact 9 immediately below the 3rd moving contact 9 ' and connect load wiring end 5.
In electromagnetic type power-off restoration switch, the magnetic force of solenoid is greater than the elastic force of back-moving spring, and the elastic force of back-moving spring is greater than the gravity of switch lever.
In physical cabling, the zero line wiring 5 ' end of electromagnetic type power-off restoration switch connects zero line, and hot terminal 5 connects live wire, and load wiring end 5 connects load, and load is connected in parallel between live wire and zero line, and live wire and zero line meet the alternating current V1 of 220V/50Hz.
Due to connection is alternating current, and alternating current exists zero crossing, and solenoid operationally, likely there will be magnet loss phenomenon.The line outlet of solenoid bottom connects zero line terminals through diode, ensures the one-way of electric current.Electric capacity is connected with between hot terminal and the anode of diode.When being in the positive half cycle of interchange, diode current flow, solenoid must conduct, capacitor charging; When being in interchange negative half period, diode ends, and solenoid and electric capacity form closed-loop path, capacitor discharge, and solenoid continues conducting, ensures the reliability of electromagnetic type power-off restoration switch.
Under the state of energising, press switch key 1, fall by External Force Acting switch lever 2, first moving contact 7 ', the second moving contact 8 ' and the 3rd moving contact 9 ' touch with corresponding fixed contact respectively, there is electric current to pass through in solenoid, produce magnetic, now unclamp hand, solenoid will adsorb switch lever 2 always, make circuit be in conducting state always.When power is off, because circuital current disappears, coil magnetic disappears, and the effect by back-moving spring 10 is recovered initial position by switch lever 2.When being again energized, because circuit disconnects, do not have electric current in coil, so do not have magnetic, cannot adsorb switch lever and three groups of contacts are connected, circuit will be in off state always.
Electromagnetic type power-off restoration switch can be widely used in total controlled switch circuit, also can be used as protection switch and uses.Electromagnetic type power-off restoration switch adopts solenoid controlled, and the simple mechanical process of clearance realizes the function of power-off restoration, and the impact by environment is very little, simultaneously with low cost, is easy to promote the use of.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this specification; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this specification, protection of the present utility model ought to be subject to.
