Abstract
A kind of method of reforming high loss distribution transformer, the method that relates to the high loss distribution transformer of standard manufactures such as a kind of JB500-64 of transformation, JB1300-73, JB1301-73, reach purpose of the present invention by coil turn, sectional area of wire, have that overload capacity is strong, temperature rise is low, good energy-conserving effect, advantages such as economic benefit is obvious are suitable for the transformation of transformer with high energy consumption is used.
Description
The present invention relates to a kind of transformation JB500-64, JB1300-73, the method for the high loss distribution transformer of standard manufactures such as JB1301-73.
Press the transformer of standard manufactures such as JB500-64, JB1300-73, JB1301-73, shortcoming such as big and load loss is big because of its no-load loss makes in the energy problem of growing tension, seems more outstanding.
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, and the method for a kind of JB500-64 of transformation, JB1300-73, JB1301-73 high loss distribution transformer is provided.
Method of the present invention is to be achieved by the following scheme: increase coil turn 25%～35%, sectional area of wire increases by 25～35%, can reach as above purpose.
It is strong that the present invention has overload capacity, and temperature rise is low, good energy-conserving effect, and advantage such as economic benefit is obvious is suitable for the transformation of transformer with high energy consumption (being JB500-64, JB1300-73, JB1301-73) is used.
According to electromagnetic induction principle, the no-load loss of transformer and no-load current mainly be due to iron core magnetic hysteresis loss and the exciting current, and core loss depend on the size of magnetic flux density, utilize iron core to increase coil turn 25～35%, make magnetic flux density descend 25～35%; In order to reduce load loss, transformer is in operation, and the copper loss that is produced in the coil is by formula I
2The R decision, during nominal load, electric current I is unalterable, reduce load loss, has only the electromagnetic wire resistance R is reduced, and for this reason, increases sectional area of wire 25～35%, makes current density reduce by 25～35%.
