Abstract
The invention discloses a method for realizing the load unbalance rate of less than or equal to 30 percent of a reduction furnace rectifier transformer. No-load loss and load loss are remarkably reduced. The reduction furnace rectifier transformer adopts a three-phase rectifier transformer which is connected with three asynchronously run loads, and the high voltage sides of the rectifier transformer are provided with a connecting circuit to make the loads form a circuit respectively, thereby providing a zero sequence current circuit. The method has the advantages that: due to the adoption of the three-phase rectifier transformer, the no-load loss and the load loss are reduced by 30 percent, the production cost is greatly reduced, and convenience is brought to transport.
Description
Technical field
The present invention relates to a kind of method of laod unbalance rate≤30% of reduction furnace rectifier transformer.
Background technology
The reduction furnace rectifier transformer needs laod unbalance rate≤30% under some specific situation, common way is that three single-phase transformers are formed the reduction furnace rectifier transformer, and three single-phase transformers move when different and realize laod unbalance rate≤30%, but owing to adopted three single-phase transformers, transformer noload losses and load loss have been increased, so just increased the manufacturing cost of transformer, three single-phase transformers are bulky simultaneously, also increased cost of transportation.
Summary of the invention
Technical problem to be solved by this invention is: the method for laod unbalance rate≤30% that the reduction furnace rectifier transformer of a kind of obvious minimizing no-load loss and load loss is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of method of laod unbalance rate≤30% of reduction furnace rectifier transformer, the reduction furnace rectifier transformer adopts a three-phase rectifier transformer, three-phase rectifier transformer connects three loads, and operation when three loads are different, and connection line is set respectively in the high-pressure side of rectifier transformer, make load form the loop, thereby the zero-sequence current loop is provided.
After the invention has the beneficial effects as follows three-phase rectifier transformer of employing, no-load loss and load loss have reduced 30%, have reduced production cost greatly, also convenient transportation.
Embodiment
Describe specific embodiments of the present invention below in detail.
The method of laod unbalance rate≤30% of reduction furnace rectifier transformer of the present invention, the reduction furnace rectifier transformer adopts a three-phase rectifier transformer, three-phase rectifier transformer connects three loads, and operation when three loads are different, high-pressure side at rectifier transformer is provided with connection line respectively, make load form the loop, thereby make three-phase rectifier transformer that the zero-sequence current loop is provided.
Advantage of the present invention is: after adopting a three-phase rectifier transformer, no-load loss and load loss have reduced 30%, have reduced production cost greatly, and convenient transportation, and floor space is little, and connection line is convenient, and is simple in structure.
