Abstract
The utility model relates to a water cooling transformer which belongs to the technical field of the improvement of a transformer. The utility model comprises a transformer, original and secondary side leads, a casing, a water inlet, a water outlet, an input end and an output end, wherein, the water inlet, the water outlet, the input end and the output end are arranged on the casing. The utility model is characterized in that the original secondary side coils of the transformer are both made of nylon sheathing enamelled wires by winding. An iron core is provided with a waterproof sealing layer, and the whole transformer is arranged in the casing filled with cooling water. The utility model has the advantages that the bulk temperature of the transformer is balanced because of water injection to the whole transformer, the load factor is enhanced, and the electric conductivity of an electromagnetic wire and the magnetic conductivity of the iron core are stable. The utility model also has the advantages of long service life, easy fabrication, low cost and small size.
Description
The utility model relates to the wet water cooled transformer of a kind of water, belongs to the improvement technical field of transformer, is applicable to any transformer that 500 volts of voltages are following, is specially adapted to the electric welder transformer manufacturing.
At present, the resistance welder transformer of widespread usage has two kinds, a kind ofly is the copper strips boring water filling of secondary or cools off former limit indirectly with the copper pipe water filling, this manufacturing process complexity, volume increases, and cooling effect is not good, load factor is difficult to improve, and the shallow leakage of secondary often makes transformer damage; Another kind be with transformer integral body with the full sealing of resin, be contained in then in the casing that is marked with cooling water, this because the heat that coiling produces makes the cold heat of sealing layer, fragile, useful life is shorter.
It is a kind of easy to manufacture that the purpose of this utility model is to provide, the water of the complete machine water filling water cooled transformer that wets.
The purpose of this utility model is achieved in that
It includes transformer, former secondary lead-in wire, the intake-outlet that is provided with on housing and the housing, input/output terminal, its technical essential is: the former secondary coil of transformer forms by the coiling of nylon sheath wire enamelled wire, has solved electric insulation and dielectric strength in the water effectively; There is one deck to play the resin encapsulation layer of waterproof action on the iron core, prevents the corrosion of medium; The transformer complete machine is contained in the housing that is marked with cooling water, and it is moved under constant temperature.
The utility model has the advantages that because the water filling of transformer complete machine, its bulk temperature equilibrium helps improving load factor, make the magnetic conductivity of the conductivity of electromagnetic wire and iron core more stable, and long service life, easy to manufacture, cost is low, and volume is little.
Fig. 1 is the utility model structural representation.
Describe the utility model in detail below in conjunction with accompanying drawing:
As shown in Figure 1, transformer 1 is fixed in the housing 10 by bracing frame 11, housing 10 is provided with water inlet 3, delivery port 7, pass to cooling water, also be provided with vent valve 12 and installation foot 9 on the housing, former limit lead-in wire 2 is connected with the input 13 of housing 10, secondary lead-in wire 4 is connected with the output 6 of housing 10, the lead-in wire place is by 5 sealings of insulated enclosure body, 8 is sealing gasket, water is not spattered outward, it is characterized in that the former secondary coil of transformer forms by nylon sheath wire enamelled wire (QYN or SYN) coiling, has solved electric insulation and dielectric strength in the water effectively; There is one deck to play the resin encapsulation layer of waterproof action on the iron core, prevents the corrosion of medium; The transformer complete machine is contained in the housing that is marked with cooling water, and it is moved under constant temperature.
