Description
Technical field
The utility model relates to a kind of capacitance energy storage type bonding machine, particularly a kind of transformer device structure of capacitance energy storage type bonding machine.
Background technology
The past corrosion resistant plate salient point welding AC resistances that adopt weld more; The secondary commutation electric resistance welding, but since the characteristic of stainless steel itself (for example: higher high temperature strength is arranged, and heat sensitivity is strong; Resistivity is high; Poor thermal conductivity) cause the heat affected area grain growth, the intercrystalline corrosion phenomenon occurs, welding effect is undesirable.So; A lot of now commercial cities of making adopt the capacitance energy storage type welding machine to carry out the projection welding of corrosion resistant plate; But, only be fit to welding than small workpiece because the problem on technology and the manufacturing process has only low power condenser discharge welder at present on the market; And, often need the high power capacity percussion welder to realize for the welding of the big workpiece of internal resistance.The high power capacity percussion welder need adopt the transformer that power is big, secondary voltage is high, and there are many difficulties in the actual high-power transformer of making, and maximum at present transformer has satisfied not the requirement of high power welding for 500KVA energy storage discharge transformer.
The utility model content
To the deficiency of above-mentioned prior art, the purpose of the utility model provides and a kind of transformer device structure more high-power, higher secondary voltage can be provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of capacitance energy storage type bonding machine transformer device structure, it comprises several transformers, and the secondary coil of said several transformers is connected whole parallelly connected in twos again, and wherein the output of first transformer and last transformer secondary output coil is connected with secondary output copper bar.
Preferably, the secondary coil of adjacent two transformers is connected through connecting copper bar in said several the transformers.
Preferably, said transformer is 500KVA energy storage discharge transformer.
Technique scheme has following beneficial effect: this capacitance energy storage type bonding machine transformer device structure is connected the secondary coil of several transformers more whole parallelly connected in twos; Secondary voltage is significantly improved; Can solve the problem that transformer-secondary voltage is reduced because of the loop is long like this, reduce current loss, avoid occurring the not enough problem of welding current; And then can effectively improve the power of bonding machine, capacitance energy storage type bonding machine integral solder ability is significantly improved.
Above-mentioned explanation only is the general introduction of the utility model technical scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification, below this patent is elaborated with the preferred embodiment and the conjunction with figs. of the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to the utility model.
As shown in Figure 1; An embodiment for the utility model; Comprise four transformers 1 among this embodiment; Transformer 1 can adopt 500KVA energy storage discharge transformer, and again through connecting copper bar 3 series connection, wherein the output of first transformer and last transformer secondary output coil is connected with secondary output copper bar 2 after the parallel connection in twos earlier of the secondary coil of four transformers 1.The same for its connected mode of more transformers with the present embodiment connected mode.
This capacitance energy storage type bonding machine transformer device structure is connected the secondary coil of several transformers more whole parallelly connected in twos; Secondary voltage is significantly improved; Can solve the problem that transformer-secondary voltage is reduced because of the loop is long like this, reduce current loss, avoid occurring the not enough problem of welding current; And then can effectively improve the power of bonding machine, capacitance energy storage type bonding machine integral solder ability is significantly improved.
More than a kind of capacitance energy storage type bonding machine transformer device structure that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum; This description should not be construed as the restriction to the utility model, and all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
