Abstract
The utility model relates to a self-coupling neon lamp transformer, one end of which is connected with the output of a zero line. The starting end X of a primary winding of an iron core 3 is connected with the zero line of a power supply, and the end A is connected with a fire wire of the power supply and connected with the starting end of a secondary high voltage winding in series to form an autotransformer. Both the starting end of the output end and the starting end X of the primary winding are connected with the zero line of the power supply by one end, and the end of the secondary high voltage winding is a high voltage output end a.
Description
The utility model is relevant with autotransformer, and is especially relevant with gas tube sign transformer.
Existing gas tube sign transformer has two high-voltage output ends, is connected with the neon light tube two ends of institute load respectively with two high-voltage cables, and makes its discharge work.Secondary high pressure winding complex manufacturing technology, because two high-tension cables of load all will be connected with two outputs of transformer, and the mounting process complexity is taken a lot of work, consume material is many, the cost height when using installation.
It is simple that the purpose of this utility model provides a kind of manufacture craft, but load short circuit work is safe in utilization, easy for installation, saving of labor, material saving, gas tube sign transformer with low cost.
The utility model is achieved in that
The top X of the elementary winding of iron core 3 is connected in the zero line of power supply, its terminal A is connected in the live wire of power supply, be in series with the top x ' of secondary high pressure winding ax ', form autotransformer, the top X of the top of its output and elementary winding is all the zero line that an end is connected in power supply, and the end of inferior extra-high voltage winding is high-voltage output end a.
Be wound with elementary winding and secondary high pressure winding on the iron core of the present utility model, between two windings magnetic shunt arranged so that load short circuits work.The top of elementary winding is connected in the zero line of power supply, and terminal top with the secondary high pressure winding is in series, and forms an autotransformer, and the top of this autotransformer is zero line, and end is a high-voltage output end.Because the terminal voltage of iron core relatively of elementary winding is supply voltage, so the top of the secondary high pressure winding that is in series with it also is supply voltage with respect to the voltage of iron core, this has just reduced the insulating requirements of secondary high pressure winding, has simplified the manufacture craft of secondary high pressure winding.This autotransformer is with respect to the common gas tube sign transformer of the same winding number of turns output voltage that raise, and changed electromagnetic property, increased the power capacity of transformer.
End in the neon light tube two ends is connected with high-voltage cable with the utility model transformer high-voltage output, and its other end is connected with zero-power line, can save a high-voltage cable; In the more neon light engineering of fluorescent tube, each organizes fluorescent tube all a zero line wiring point, so can publicly be connected in the zero line of power supply, makes installing engineering saving of labor, material saving.
Fig. 1 is an electrical schematic diagram of the present utility model.
Fig. 2 is the utility model profile schematic diagram.
Fig. 3 is a kind of electrical connection diagram of the utility model and neon light tube.
Following is embodiment of the present utility model:
The utility model has the iron core 3 in shell 1 and the shell.Be wound with elementary winding and secondary high pressure winding on the iron core 3.Between two windings magnetic shunt is arranged.Elementary winding has A, two power inputs of X.The A end is connected with power firestreak, and the X end is connected with zero-power line.Ax ' is former secondary high pressure winding, forms autotransformer winding aX after the A end is connected with x ' end, and promptly the top of secondary high pressure winding also is the X end, and is connected with zero-power line, and end is high-voltage output end a, and insulator 2 is arranged.
When installing and using, as shown in Figure 3, L represents the neon light tube group, the T indication transformer, and C represents high-voltage cable, has enumerated three groups of fluorescent tubes and three groups of transformers in the present embodiment.This shows, compare with common gas tube sign transformer, simplified project installation, buckle is installed is beaten the hole of half less, the saving of labor saves half high-voltage cable.
