Building-block-combined-type high power transformer

Abstract

A building-block-combined-type high power transformer includes a first iron core body, a second iron core body, a plurality of plate bodies, and a plurality of isolating bodies. The first iron core body and the second iron core body have a first side wing part and a second side wing part respectively at both sides thereof. Both of the first side wing part and the second side wing part being a circular shape at both ends respectively thereof have a first open channel and a second open channel formed between thereof where the second iron core body is in contact with the first iron core body. Each of the plate bodies being positioned in both the first open channel and second open channel has an open hole, for containing both of the first side wing part, and the second side wing part, and a guided channel that is positioned on the second side of the open hole. The isolating bodies being annular in shape and being positioned in between the first plate bodies and the second plate bodies have a through hole corresponding to the open hole for containing the first side wing part and the second side wing part.

Description

technical field [0001] The invention relates to a transformer structure, in particular to a building block combination high-power transformer used in large wattage (more than 3000 watts) by using the principle of building block combination. Background technique [0002] In recent years, due to the rapid development of high-tech technology, especially in the field of microelectronics related technology and process, electronic related products have penetrated into every family and all walks of life and become an indispensable part of modern life. [0003] The traditional transformer used to drive the backlight module lamp inside the liquid crystal display (LCD) has a coil base, which has a primary line area and a secondary line area, and a plurality of terminals are provided at both ends for connecting the wires of the winding and soldering to the circuit. plate. Due to the continuous advancement of technology and the demand for high brightness of LCD displays, some manufactu...

AI Technical Summary

Problems solved by technology

Due to the continuous advancement of technology and the demand for high brightness of LCD displays, some manufacturers have increased the number of lamps used in the backlight module of the LCD display, and the number of transformers used will also increase. In this way, Not only does it cause the volume of the liquid crystal display to become larger, but the relative weight also becomes heavier.

Therefore, some operators will use a single transformer to drive multiple lamps. If the transformer mentioned above is used to drive multiple lamps, the voltage of the transformer must be increased to match its high power output; if so, use a single transformer to drive When there are multiple lamp tubes, the primary coil and the secondary coil are all wound on the same bobbin, so that the winding area of ​​the primary coil is limited. Therefore, if the voltage output is increased according to the needs of the transformer, the primary wire area and the secondary wire area The number of coils on the transformer must become larger, which leads to an increase in the thickness of the transformer and a relative increase in its overall volume

[0004] Secondly, when the load power increases, the primary coil part will have an obvious temperature rise problem, which may cause the transformer to overheat

If the wire diameter of the primary side winding coil is thickened, the problem of temperature rise can be solved slightly, but the thickness of the coil is increased, which makes the thickness of the transformer even more; in addition, in the above common transformers, if it is necessary to consider The safety isolation of the primary coil and the secondary coil on the same bobbin is more difficult in the withstand voltage of the high-voltage winding, which has a relatively adverse impact on the manufacturing and cost of transformer parts

In addition, for high-power transformers, large-scale iron cores need to be produced, and large-scale die-casting machines must be used to produce them, which makes the production cost relatively expensive. Therefore, how to solve the above problems has always been an urgent solution and improvement that the industry needs to seek.
