Abstract
The utility model belongs to the technical field of silicon-controlled welding machines, and discloses a main transformer for a silicon-controlled welding machine. The main transformer for the silicon-controlled welding machine comprises an upper clamp plate and a lower clamp plate, an iron core is arranged between the upper clamp plate and the lower clamp plate, a winding is arranged on the iron core, and a primary coil and a secondary coil of the winding are respectively connected with a central seal head and an aluminum wire nose, and fiber air channel strips are arranged between the primary coil and the secondary coil of the winding. By arranging the fiber air channel strips between the primary coil and the secondary coil of the winding, ventilating speed of radiation of the secondary coil of the transformer is increased, a resistance value is increased, the problem that insulation degree of the primary coil is influenced due to over-high temperature is solved, and iron properties are increased.
Description
Technical field
The utility model relates to a kind of silicon controlled welding machine, specifically refers to a kind of silicon controlled welding machine main transformer.
Background technology
The transformer chief component is iron core and winding; Core material is to add silicon in the iron plate, can reduce the conductivity of steel disc, increases resistivity, and it can reduce eddy current, and its loss is reduced.Transformer has the characteristics of self, has exactly the characteristic that voltage is sharply descended.Difform iron core and winding mode have caused the function of transformer different.
Since the primary coil of the main transformer of silicon controlled welding machine flat around, vertical around secondary coil after the insulation, cause so the primary and secondary coil heat radiation of main transformer of silicon controlled welding machine bad, temperature rise is higher, arcing time factor reduces.
The utility model content
The purpose of this utility model is to overcome defective of the prior art and a kind of silicon controlled welding machine main transformer is provided, and is intended to solve existing silicon controlled welding machine main transformer primary and secondary coil heat radiation bad, and temperature rise is higher, the problem that arcing time factor reduces.
For achieving the above object, the scheme of the utility model employing is as follows;
A kind of silicon controlled welding machine main transformer comprises train wheel bridge and lower plate, is provided with iron core between described train wheel bridge and lower plate, is provided with winding at described iron core, and the primary coil of described winding and secondary coil are connected with respectively center end socket and aluminum steel nose; Between the secondary coil of described winding and primary coil, be provided with fiber air channel bar.
Described iron core is to be formed by the silicon steel sheet stack.
The utility model is by being provided with fiber air channel bar between the primary and secondary coil of winding, increase the ventilation speed of transformer primary and secondary coil heat radiation, the iron core heat radiation is accelerated, increased resistance value, improved because of the affected problem of the elementary line coil insulation of excess Temperature degree, increased core characteristics.
Description of drawings
Fig. 1 is the structural representation of the silicon controlled welding machine main transformer that provides for the utility model embodiment;
Fig. 2 is the local enlarged diagram of Fig. 1;
Among the figure: 1 is that secondary coil, 2 is that end socket centered by the primary coil, 3,4 is that train wheel bridge, 5 is that aluminum steel nose, 6 is that iron core, 7 is that lower plate, 8 is fiber air channel bar.
Embodiment
Below in conjunction with example substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed embodiment.
Referring to shown in Figure 1, the figure shows a kind of silicon controlled welding machine main transformer structure that the utility model embodiment provides, for convenience of explanation, only show the part relevant with the utility model embodiment.
A kind of silicon controlled welding machine main transformer, comprise train wheel bridge 4 and lower plate 7, between described train wheel bridge 4 and lower plate 7, be provided with iron core 6, be provided with winding at described iron core 6, be connected with respectively center end socket 3 and aluminum steel nose 5 at primary coil 2 and the secondary coil 1 of described winding; Between the secondary coil 1 of described winding and primary coil 2, be provided with fiber air channel bar 8.
Described iron core 6 is to be formed by the silicon steel sheet stack.
The utility model is by being provided with fiber air channel bar between the primary and secondary coil of winding, increase the ventilation speed of transformer primary and secondary coil heat radiation, the iron core heat radiation is accelerated, increased resistance value, improved because of the affected problem of the elementary line coil insulation of excess Temperature degree, increased core characteristics.
The above only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
