Abstract
The invention discloses a kind of parallel resonance intermediate frequency power supply starter, including smoothing reactor, A.C. contactor, capacitor, wherein capacitor is connected with A.C. contactor, and capacitor is connected in parallel on after connecting with A.C. contactor in one group of coil of flat ripple electric controller.The present invention, by magnetizing in advance to smoothing reactor, is greatly improved the success rate that inversion starts, brings considerable economic benefit for user；The arc light that the A.C. contactor of short circuit smoothing reactor produces when discharging simultaneously is little, and the main contact of A.C. contactor is hardly damaged, and extends the service life of A.C. contactor, reduces the fault rate of equipment.
Description
Technical field
The present invention relates to a kind of power source starting apparatus, particularly relate to a kind of parallel resonance intermediate frequency power supply starter.
Background technology
At present, state's internal intermediate frequency fusing stove uses the equipment of parallel resonance mode mostly to use still in leading position, Starting mode
Frequency sweep Starting mode, circuit is fairly simple, easy to maintenance, but the control circuit because using is different, the difference of instrument size,
Starting complexity also to differ, all there is certain problem in these Starting mode: has plenty of fully loaded black furnace difficulty and start；Have
It is that fully loaded hot stove difficulty starts, can start again after waiting furnace charge cooling；Have is even fully loaded with and cannot start, and having no alternative have to be stove
Son is destroyed, again brickwork；These problems all bring huge economic loss to user, and the biggest economic loss of stove is the biggest.
Summary of the invention
For overcoming the defect of prior art, it is an object of the invention to provide a kind of parallel resonance intermediate frequency power supply starter.
For achieving the above object, the technological means that the present invention is taked is: parallel resonance intermediate frequency power supply starter, including putting down
Wave reactor, A.C. contactor, capacitor, wherein capacitor is connected with A.C. contactor, capacitor and A.C. contactor string
It is connected in parallel on after connection in one group of coil of flat ripple electric controller.
Further, described capacitor is non-polar condenser.
Further, described capacitor is self-healing the parallel power condenser.
Further, NC3 (CJ46)-85 selected by described A.C. contactor, and BSMJ0.45-10-3 selected by capacitor.
The invention has the beneficial effects as follows: by magnetizing in advance to smoothing reactor, be greatly improved the success rate that inversion starts,
Considerable economic benefit is brought for user；The arc light that the A.C. contactor of short circuit smoothing reactor produces when discharging simultaneously is little,
The main contact of A.C. contactor is hardly damaged, and extends the service life of A.C. contactor, reduces the fault rate of equipment.
Accompanying drawing explanation
Below in conjunction with view and embodiment, the present invention is described in detail.
Fig. 1 is the 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 line
Circle two.
Detailed description of the invention
Parallel resonance intermediate frequency power supply starter, including smoothing reactor, A.C. contactor, capacitor, wherein capacitor with
A.C. contactor is connected, and capacitor is connected in parallel on after connecting with A.C. contactor in one group of coil of flat ripple electric controller.
Further, described capacitor is non-polar condenser.
Further, described capacitor is self-healing the parallel power condenser.
Further, NC3 (CJ46)-85 selected by described A.C. contactor, and BSMJ0.45-10-3 selected by capacitor.
As it is shown in figure 1, select NC3 (CJ46)-85 A.C. contactor, a BSMJ0.45-10-3 self-healing parallel connection electricity
Power capacitor, when pinning inversion button, AC contactor main contact 1 adhesive, by capacitor 2 and smoothing reactor coil
One 3 is in parallel, magnetizes smoothing reactor in advance, after intermediate frequency power supply starts successfully, unclamps inversion start button, make exchange connect
Tentaculum main contact 1 discharges, and capacitor 2 just disengages, and intermediate frequency equipment normally works.It should be noted that actually used time,
It is equipped with A.C. contactor size, condenser capacity according to practical situation, and needs the how many smoothing reactor coil of short circuit, so that
Make intermediate frequency power supply easily start to be advisable.
The above, for the detailed description of the invention of the present invention, it is not limited to this, any technology people being familiar with the art
Member, in the technical scope that the present invention shows, can readily occur in change or the mode replaced, should contain the protection in the present invention
Within the scope of.
