Abstract
The utility model discloses a symmetrical magnetic-saturation voltage regulator. An iron core with five core columns are utilized. The primary winding, the secondary windings and the direct current winding of the voltage regulator are symmetrically arranged at the left and the right sides of a third core column. The windings at the left and the right sides of the third core column are winded oppositely. Since the iron core of the utility model is added with the third core column, a main magnetic flux is formed with a loop respectively between the core columns 1 and 2 and 4 and 5 when no direct current excitation exists. The induction potential of the secondary windings are counteracted mutually, output voltage is zero. When rated direct current excitation exists, the main magnetic flux is formed with the loop between the core columns 1 and 5, the value of output voltage is maximum, and therefore, the range of voltage regulation is widened.
Description
The utility model belongs to the voltage regulator product, is a kind of symmetrical expression magnetic saturation voltage regulator.
" motor engineering handbook " the 25th piece discloses a kind of magnetic voltage regulator structural principle, use generally at present, thereby this product is to reach the purpose that changes the output voltage U value by the current values that changes dc coil K.Its structure as shown in Figure 2, the weak point of this structure is to be symmetrically placed in the voltage value of the winding of equal turn numbers on two iron props and unequal.Problem is, because core structure causes magnetic flux distribution inhomogeneous.Therefore the adjustable range of secondary winding output voltage U is little.
The purpose of this utility model is to overcome the drawback of said structure and designs a kind of five novel stem stem core structures, constitutes the direct current flux loop by the 3rd iron prop of setting up, to guarantee the iron core magnetic flux distribution symmetrically.Increased the adjustable range of output voltage simultaneously.
The purpose of this utility model realizes by following technical measures: on iron core with five stem stems, and the left and right sides that is arranged in the 3rd stem stem of winding, secondary winding and a direct current winding symmetry.A winding parallel connection on the 1.2nd and 4.5 stem stems, the turn ratio of two windings should equal the ratio of the magnetic resistance value of these two stem stems on the 1st, 2 stem stems and 5.4 stem stems, secondary windings in series is distributed on the stem stem 1,2,4,5, the equal turn numbers of winding on each stem stem.
In conjunction with the accompanying drawings concrete structure of the present utility model and operation principle are described in further details.
Fig. 1 is the utility model structure principle chart.
Fig. 2 is the magnetic voltage regulator structure principle chart.
With reference to Fig. 1, the five stem stem iron cores that iron core of the present utility model is made up of stem stem 1,2,3,4,5 constitute, a winding 6, and the left and right sides that is arranged in stem stem 3 of secondary winding B and direct current winding K symmetry is distributed in the direct current on the stem stem 2,4.Umber of turn equates, around on the contrary, and a winding parallel connection on the stem stem 1.2 and 4.5, two winding G on stem stem 1,2 and stem stem 5,4 and B
1Turn ratio should equal the ratio of the magnetic class value of these two stem stems, be distributed in a winding 6 on stem stem 1,2 and 4,5 around to opposite and draw wiring A, x, secondary winding B
2Series arrangement is at stem stem 1,2,4, on 5, and equal turn numbers, and be distributed in stem stem 1, winding on 2 be distributed in 4, winding on 5 stem stems is around on the contrary, and draw wiring a, x, the utility model is owing to set up stem stem 3, make stem stem 2, a winding on 4 can adopt the connect in parallel mode, when no dc magnetizing, main flux is respectively from stem stem 1,2 and stem stem 4,5 constitute the loop, because the induced potential of each secondary winding is cancelled out each other, output voltage is zero this moment, and when specified dc magnetizing, main flux is only at stem stem 1,5 form the loop, and this moment, therefore the output voltage values maximum increased the voltage-regulation scope.
