Description
Technical field
The utility model relates to transformer, particularly relates to step down side copper bar outgoing line device, belongs to field of electrical equipment.
Background technology
At present, most of transformer low voltage lateral coils (low-voltage coil pour mass) adopt direct lead outlet method, and the processing of carrying out around-packing technology by the lead-in wire to low-voltage coil realizes the connecting mode of step down side.Yet configuration design size at existing product, under the restrictive condition of technology, (as: surrounding environment is moist under than condition of severe when product operates in environment, air humidity is bigger, when easily producing condensation), because in existing transformer, directly low-pressure side (low-voltage coil) outlet under the lead outlet method is smaller to the insulation distance of high-tension coil, can only guarantee the distance of 15～20mm, cause transformer in use to have following several shortcoming: the one, the step down side dielectric strength can not satisfy customer requirements, it is bigger to beat withstand voltage sound, and creepage distance is not enough; The 2nd, the around-packing technology of lead junction, the insulating material of employing will directly influence the quality of power transformer product, and the connecting line that carries out wrapped processing with insulating material lacks stability in use in running; The 3rd, adopt the power transformer product low-pressure side outward appearance of directly quoting the lead outlet not attractive in appearance, the man-hour that needs in coil winding, total process of assembling is long, difficulty is bigger.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provide a kind of lead of lifting one's head of step down side in limited space, to be improved to the insulation distance of high-tension coil, low-pressure side is lifted one's head lead outlet insulation property height, ampacity promotes, pick out reliably, and step down side step down side copper bar outgoing line device aesthetic in appearance.
The technical scheme of the utility model step down side copper bar outgoing line device is: comprise high-tension coil pour mass, low-voltage coil pour mass, be installed in the iron core of low-voltage coil pour mass inboard, and fixedly the upper and lower folder of high and low pressure coil pour mass is formed, the low-voltage coil pour mass has the lead of lifting one's head, it is characterized in that on the low-voltage coil pour mass installing copper and lift one's head row, copper is lifted one's head row and is welded and lift one's head lead.
Step down side copper bar outgoing line device of the present utility model, adopt soldering copper to lift one's head row's outlet method and replace the outlet of existing direct employing lead, its advantage has: one, the outlet of step down side is brought up to more than the 50mm in limited space to the insulation distance of high-tension coil, creepage distance is long, the usage safety performance of transformer under the environment condition of severe is greatly improved, and operational reliability is also improved relatively; Two, the low-pressure side transformer that adopts up-to-date copper to lift one's head to discharge line carry out that common frequency is withstand voltage, lightning impulse, office puts that remarkable result is all arranged in the experiment, has guaranteed the insulation property of product, promotes ampacity, the reliability that picks out is also improved accordingly; Three, to lift one's head the transformer of discharging the line mode aesthetic in appearance for copper, saves man-hour in low-voltage coil processing, transformer group process of assembling.
Step down side copper bar outgoing line device of the present utility model, its described lead of lifting one's head comprises zero line and phase line, described copper is lifted one's head package and is drawn together zero line copper and lift one's head row and phase line copper and lift one's head row, zero line welding zero line copper is lifted one's head row, phase line welding phase line copper is lifted one's head row, zero line copper is lifted one's head row and phase line copper and is lifted one's head row and low-voltage coil pour mass one cast, and it is firm that copper is lifted one's head row's installation.
