Abstract
The utility model relates to a transformer for a high-voltage neon lamp, which is specifically provided with a capacitor and an inductance coil. The utility model is characterized in that one end of the capacitor is connected with one end of the inductance coil; the other end of the capacitor and the other end of the inductance coil are respectively connected with both ends of a primary winding. The utility model has the advantages of high power factor, small power consumption and energy saving.
Description
The utility model relates to a kind of transformer.
Existing high pressure gas tube sign transformer mainly is made of iron core and the primary and secondary winding that is wound on the iron core, and its power factor (PF) is lower, power consumption is also bigger.For example, existing output voltage is the high pressure gas tube sign transformer of 15KV, and its power consumption reaches 450VA, and power factor (PF) only is about 0.5.Therefore, existing high pressure gas tube sign transformer exists certain defective.
The purpose of this utility model provides the high pressure gas tube sign transformer that a kind of power factor (PF) is higher, power consumption is less.
High pressure gas tube sign transformer of the present utility model has the primary and secondary winding that is wound on the iron core.In transformer, be provided with capacitor and inductance coil especially, an end of capacitor and an end of inductance coil join, and the other end of capacitor and the other end of inductance coil join with the two ends of elementary winding respectively.Also that is to say, capacitor is with after inductance coil is connected in series, in parallel with elementary winding again.Like this, in the transformer use, though after the current hysteresis on the elementary winding, but it is leading with the electric current on the capacitor that inductance coil is connected in series, thereby the power factor (PF) of compensator transformer effectively, make transformer itself no longer with the power supply positive energy exchange, and only inner by the capacitor positive energy exchange at transformer.Therefore, as a whole, the apparent power that transformer is drawn from power supply will greatly reduce, and produce remarkable energy saving effect.
In the utility model, can be on same iron core with the inductance coil set up and elementary winding technique, this helps producing bigger offset current, further improves power factor (PF).
Transformer of the present utility model is compared with existing gas tube sign transformer, has that power factor (PF) height, power consumption are little, the characteristics of energy savings.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the electrical block diagram of transformer among the embodiment.
As shown in Figure 1, the high pressure gas tube sign transformer among the embodiment has elementary winding L 1, secondary winding L2, capacitor C and inductance coil L3, and inductance coil L3 is wound on the same iron core with elementary winding L 1.In the present embodiment, capacitor C is with after inductance coil L3 is connected in series, and is in parallel with elementary winding L 1 again.
In the present embodiment, the output voltage of transformer is 15KV, and its power consumption is 160VA, and power factor (PF) is 90%.Compare with aforementioned existing gas tube sign transformer, have remarkable energy saving effect.
