Description
Technical field
The utility model relates to a kind of low-voltage outgoing-line copper bar structure of transformer.Belong to essential electronic element technical field.
Background technology
For low-voltage high-current transformer, as rectifier transformer or furnace transformer, what existing box lid type low-pressure line-outgoing adopted is the epoxy pouring type conducting copper shown in Fig. 1, and its rated current-carrying capacity is no more than 1.7A/mm according to maximum current density
2determine, the low-tension current of transformer is larger, and low-pressure line-outgoing copper bar consumption is more.
Simultaneously, an objective reality is: in smelting system, and the electric furnace of high-temperature operation, in order to the normal work of support equipment and useful life, must be equipped with a set of water cooling system, in commutation system, the controllable silicon in rectifier cabinet and the copper bus-bar that confluxes all adopt pure water cooling unit to cool.
Utility model content
The purpose of this utility model overcomes background technology mesolow outlet copper bar current density to select low problem, and a kind of novel transformer Low Voltage and Water-cooled outlet copper bar provided, particularly in smelting and commutation system, do not needing additionally to increase investment, when the water cooling system of utilization own cools, greatly can reduce the copper bar consumption of transformer low voltage outlet.
The utility model processes on the basis of the conducting copper of epoxy pouring type shown in Fig. 1.Described transformer low voltage water-cooled outlet copper bar is as Fig. 2, structure comprises: conducting copper (1), U-shaped water-cooling copper pipe (2), epoxy resin insulating layers (3), copper water nozzle (4), fixed copper nut (5).
Described U-shaped water-cooling copper pipe (2) is processed into U-shaped, is welded on the side of conducting copper (1).
The two ends of described U-shaped water-cooling copper pipe (2), one end is water inlet, and one end is delivery port, respectively the upper fixed copper nut (5) of welding, and seals fixed copper water nozzle (4).
When using, the water inlet of the U-shaped heat dissipation copper pipe (2) on all for transformer water-cooled outlet copper bars and delivery port are concatenated successively by pinching solid plastic flexible pipe on copper water nozzle (4), form a through water route, access water cooling system, by the circulation of cooling water, the caloric value of transformer outlet copper bar is taken away, thus compared with prior art epoxy pouring type conducting copper, significantly can improve the specified current carrying density of transformer low voltage outlet copper bar, when considering to control busbar loss, current density at least can bring up to 5A/mm
2left and right, thus effectively can reduce the consumption of transformer low voltage outlet copper bar, reduces the material cost of transformer.
