Abstract
The invention discloses a parallel resonant intermediate frequency power supply starting device which comprises a flat wave electric reactor, an AC contactor and a capacitor. The capacitor is connected in series with the AC contactor and then connected in parallel in a group of coil in a flat wave electric controller. The flat wave electric reactor is magnetized in advance so that success rate of inverting starting is greatly enhanced and considerable economic benefits are brought to users; meanwhile, arc light generated by releasing the AC contactor which is used for short connecting the flat wave electric reactor is small so that a main contact of the AC contactor is not liable to be damaged, the service life of the AC contactor is prolonged and fault rate of the device is lowered.
Description
Technical field
The present invention relates to a kind of power source starting apparatus, relate in particular to a kind of parallel resonance intermediate frequency power supply starting drive.
Background technology
At present, state's internal intermediate frequency melting furnace adopts the equipment of parallel resonance mode still in leading position, Starting mode mostly adopts the frequency sweep Starting mode, circuit is fairly simple, easy to maintenance, but the control circuit difference because adopting, the difference of instrument size, start complexity also not identical, all there is certain problem in these Starting mode: have plenty of the difficult startup of fully loaded black furnace; Have plenty of that fully loaded hot stove is difficult to be started, can start again after waiting furnace charge cooling; That have or even fully loaded can't the startup, have no alternative and have to destroy stove, again brickwork; These problems have all been brought huge economic loss to the user, and the larger economic loss of stove is larger.
Summary of the invention
For overcoming the defect of prior art, the object of the present invention is to provide a kind of parallel resonance intermediate frequency power supply starting drive.
For achieving the above object, the technological means that the present invention takes is: parallel resonance intermediate frequency power supply starting drive, comprise smoothing reactor, A.C. contactor, capacitor, wherein capacitor is connected with A.C. contactor, capacitor be connected in parallel in one group of coil of flat ripple electric controller after A.C. contactor is connected.
Further, described capacitor is non-polar condenser.
Further, described capacitor is the self-healing the parallel power condenser.
Further, described A.C. contactor is selected NC3 (CJ46)-85, and capacitor is selected BSMJ0.45-10-3.
The invention has the beneficial effects as follows: by the magnetizing in advance of smoothing reactor, greatly improve the success rate that inversion starts, for the user has brought considerable economic benefit; The arc light that the A.C. contactor that the short circuit smoothing reactor is used simultaneously produces while discharging is little, and the main contact of A.C. contactor is not fragile, has extended the useful life of A.C. contactor, has reduced the failure rate of equipment.
The accompanying drawing explanation
Below in conjunction with view and embodiment, the present invention is described in detail.
Fig. 1 is schematic block circuit diagram of the present invention;
In figure: 1, AC contactor main contact, 2, capacitor, 3, flat ripple electric controller coil one, 4, flat ripple electric controller coil two.
Embodiment
Parallel resonance intermediate frequency power supply starting drive, comprise smoothing reactor, A.C. contactor, capacitor, and wherein capacitor is connected with A.C. contactor, capacitor be connected in parallel in one group of coil of flat ripple electric controller after A.C. contactor is connected.
Further, described capacitor is non-polar condenser.
Further, described capacitor is the self-healing the parallel power condenser.
Further, described A.C. contactor is selected NC3 (CJ46)-85, and capacitor is selected BSMJ0.45-10-3.
As shown in Figure 1, select a NC3 (CJ46)-85 A.C. contactor, a BSMJ0.45-10-3 self-healing the parallel power condenser, when pinning the inversion button, AC contactor main contact 1 adhesive, capacitor 2 is in parallel with smoothing reactor coil 1, smoothing reactor is magnetized in advance, after intermediate frequency power supply starts successfully, unclamp the inversion start button, AC contactor main contact 1 is discharged, and capacitor 2 is just thrown off, the normal operation of intermediate frequency equipment.It should be noted that, during actual the use, according to actual conditions, be equipped with the A.C. contactor size, condenser capacity, and need the how many smoothing reactor coils of short circuit, easily start and be advisable to cause intermediate frequency power supply.
The above, be the specific embodiment of the present invention, is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention shows, can expect easily the mode that changes or replace, within all should being encompassed in protection scope of the present invention.
