Description
Technical Field
The utility model relates to a fill electric pile technical field, specifically indicate a fill electric pile resistance to transformer with electricity.
Background
With the development of social industrialization becoming faster and faster, energy conservation is a struggle target, so more and more machines are driven by electric energy, especially automobiles and battery cars; in order to charge the machines, more and more charging piles are required to be arranged, and when the charging piles charge various machines, if the machines are directly electrically connected with the charging piles, the rectifier elements and the transformer are inevitably damaged due to the large current of the charging piles.
In order to prevent the impact and damage of large current to the rectifying element and the transformer when the charging pile is charged, the impedance of the transformer is usually made large. Generally, the impedance of a transformer with concentrically arranged coils cannot be made large, which requires a reactor to be connected in series in the primary or secondary circuit of the transformer. The transformer with the series reactor has large volume, occupies space and wastes materials.
SUMMERY OF THE UTILITY MODEL
Based on above problem, the utility model provides a fill electric pile resistance to transformer with electricity. The utility model discloses can realize practicing thrift the electromagnetic wire, the purpose that occupation space is little through the sharing coil, has solved and has filled that series reactor leads to bulky on the transformer among the electric pile now, occupation space and the problem of extravagant material.
For solving the above technical problem, the utility model discloses a technical scheme as follows:
the utility model provides a fill anti transformer of electric pile, includes the base, vertical transformer core and the reactor iron core that sets up the length the same on the base, the cover has first electromagnetic wire spiral wound's inner coil on the transformer core, the partly spiral wound's of inner coil overcoat second electromagnetic wire outer coil, another part spiral winding of second electromagnetic wire is in the outer coil with the whole appearance that the reactor iron core constitutes jointly becomes common coil, be provided with the stay between inner coil and the outer coil, between outer coil and the common coil.
The utility model discloses in, vertically place the transformer core and the reactor core that length is the same on the base, with first electromagnetic wire wound into spiral coil, the cover constitutes the inner coil on the iron core of transformer, overlaps the partly spiral wound coil of second electromagnetic wire cover on the inner coil, another part continues to wound into spiral coil, will inner coil and reactor core regard as a whole cover above, and be used in inner coil between the outer coil, set up the stay between outer coil and the common coil. The reason for this arrangement to save material is as follows:
suppose that: the iron core section of the split reactor is S1Number of turns of coil W1The inductance of the iron core reactor is
L1∝S1×W1 2
And: the iron core section of the integral reactor is S2The cross section of the transformer core is S3The number of common coil turns is W2The inductance of the reactor is
L2∝(S2+S3)×W2 2
To make both inductors L1And L2Equal, there are:
S1×W1 2＝(S2+S3)×W2 2
compared with the above formula, the section of the integrated total iron core is generally larger than that of the split type reactor iron core (S)2+S3) ＞S1Therefore, the number of turns of the common coil is less than the number of turns W of the coil of the split reactor2 2＜W1 2
The iron core section of the reactor in the integrated structure is smaller than the iron core section S of the split reactor2＜S1
Thus, there are: s2×W2 2＜＜S1×W1 2That is to say, the integral reactor iron core has a small section and a small number of turns. This is why the one-piece reactance transformer saves material.
And compared with a reactor coil and a transformer coil, the common coil with the rectangular cross section has two shorter sides of the rectangle, so that a plurality of electromagnetic wires are saved.
Preferably, the first magnet wire and the second magnet wire are fixedly connected with lead wires at both ends.
Preferably, the reactor core is formed by stacking laminated sheets of the same size.
As a preferable mode, an air gap plate is arranged between the lamination stacks of the reactor core, vertical pulling plates are respectively arranged on the front side and the rear side of the lamination stack of the reactor core, through holes are respectively arranged at the upper end and the lower end of each pulling plate, and bolts penetrate through the through holes to connect the pulling plates on the front side and the rear side.
As a preferred mode, the base is provided with supporting legs, the lower ends of the supporting legs are connected with horizontally arranged supporting foot plates, and foot plate holes are formed in the positions, far away from the supporting legs, of the supporting foot plates.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the utility model discloses can realize practicing thrift the electromagnetic wire, reduce reactance transformer occupation space's purpose, through sharing coil, it leads to the volume very big to have solved the current series reactor that needs on the transformer among the electric pile that fills, occupation space and the problem of extravagant material.
(2) The utility model discloses a both ends of first electromagnetic wire and second electromagnetic wire are all fixed connection have the lead wire, are convenient for fill electric pile resistance to transformer with electric and other electrical components and link to each other.
