Description
Technical field
The utility model relates to integrated non-noise AC contactor with very-low energy consumption, belong to A.C. contactor
Technical field.
Background technology
The A.C. contactor of existing various series, because it adopts U type or E sections core to power up the start of magnetic zygonema circle, fixed contact contact power, thereby as long as A.C. contactor work, the electromagnetism pull-in winding just has electric current to pass through, it must consume certain electric energy, and along with the difference of the big low capacity of A.C. contactor, its pull-in winding power consumption from several watts (VA) to several hectowatts (VA), so just there is the electric energy of several hundred million degree (during KVA/) every year in the whole nation by invisible slatterning, and noise and thermal pollution environment are arranged.
Summary of the invention
The objective of the invention is defective, propose integrated non-noise AC contactor with very-low energy consumption at above-mentioned existence.The simpler related mould of its structure is changed seldom, is more conducive to a large amount of productions, has increased closed loop self-checking circuit and insurance circuit on the circuit simultaneously, so reliability is higher.Technical solution of the present invention: its structure is that upper core is arranged, upper core is fixed in the support, it below upper core lower core, it is divided into two, and places permanent magnet in the middle of it, is with bucking coil and electromagnetism pull-in winding on four end face bodies of lower core, bucking coil connects capacitor discharger, lower core is the pole shoe of permanent magnet, and lower core is fixed on the base, between base and support the bounce-back spring is arranged.
Advantage of the present invention: from being disconnected to connection work, the electromagnetism pull-in winding only needs instantaneous energising, in case just outage automatically of work, so be not subjected to the influence of voltage ripple of power network, pull-in winding is excused from a college course all the life; During operate as normal, the power moving, that fixed contact contacts is from the suction in permanent magnet magnetic field, in the life-span that this suction keeps weighing apparatus to help improving moving fixed contact surely, the pull-in winding no current passes through simultaneously, has therefore saved a large amount of electric energy, realize noiseless, heat operation, environment purification; Reduce inductive loads in the electrical network in a large number, therefore improved the effect factor of power supply grid; The repertoire that possesses existing A.C. contactor.

Embodiment
Contrast Fig. 1, upper core 2 is arranged, upper core 2 is fixed on supports to be lower core 3 on 1 below upper core 2, it is divided into two, place permanent magnet 6 in the middle of it, be with bucking coil 5 and electromagnetism pull-in winding 4 on four end face bodies of lower core 3, bucking coil 5 connects capacitor discharger 10, and lower core 3 is pole shoes of permanent magnet 6, lower core 3 is fixed on the base 8, and base 8 and 1 of support have bounce-back spring 9.
Contrast Fig. 2, described capacitor discharger 10, it comprises the bridge rectifier of being made up of diode D1-D4, current-limiting resistance R1, diode D5, capacitor C 1, controllable silicon BG1, the negative terminal of diode D2 in the bridge rectifier is connected in series with current-limiting resistance R1, diode D5, capacitor C 1, the negative electrode of the negative terminal of capacitor C 1 and controllable silicon BG1 joins, and the anode of controllable silicon BG1 connects bucking coil 5; The negative terminal of diode D5 in the capacitor discharger 10 and the anode of the diode D6 in the closed loop self-checking circuit join, and the negative terminal of the diode D6 in the closed loop self-checking circuit is connected in series with the trigger electrode of bucking coil (5), switch (CJ1-1), resistance (R9), controllable silicon BG3; The anode of controllable silicon BG1 in the capacitor discharger 10 and the controllable silicon BG2 anode in the insurance circuit join, insurance circuit is made up of diode (D7), resistance R 8, controllable silicon BG2, mains switch TA, the anode of mains switch TA normal opened contact and diode D7, resistance R 8 are joined, the trigger electrode of the other end of resistance R 8 and controllable silicon BG2 joins, and the negative terminal of diode D7 connects bucking coil 5.
The course of work:
The closed loop self-checking circuit, the peak voltage through setting up on capacitor C 1 behind the bridge rectifier is about 1.3 times of supply voltage, and this voltage is added to the anode of controllable silicon BG1, BG2 by bucking coil 5.And by switch CJ
1-1The normally closed contact trigger voltage of resistance R 9 of feeding as controllable silicon BG3; When if capacitor discharger 10 and bucking coil 5 have fault not have direct voltage output, even Press knob down switch QA makes supply voltage can not make its conducting through the anode that pull-in winding 4 is added to controllable silicon BG3, A.C. contactor can't start, the operation principle of Here it is closed loop self-checking circuit.A.C. contactor could start when relevant elements such as bucking coil 5 are working properly only at capacitor discharger 10, otherwise will refuse starting, and this just effectively guarantees to discharge reliably.
