Abstract
The utility model relates to a neon lamp transformer, which comprises a shell body and an electromagnetic transformer composed of an iron core, a low-voltage coil and a high-voltage coil. The neon lamp transformer is characterized in that the low-voltage side of the transformer is also provided with a power-factor compensator composed of a compensating coil and a capacitor, and a protector composed of a bidirectional diode mutually connected in parallel with the low-voltage coil and a voltage dependent resistor mutually connected in parallel with the high-voltage coil. The utility model has the characteristics that the neon lamp transformer can raise power factor and reduces reactive power loss; the self work efficiency of the transformer is made to be enhanced obviously; the purpose of energy saving is achieved. In addition, because the protective and corona resisting technical measure is added, the reliable performance is enhanced.
Description
The utility model relates to a kind of gas tube sign transformer that neon-light advertisement is lighted neon light tube that is used to make.
The gas tube sign transformer of domestic production at present mainly contains two kinds, and a kind of is induction gas tube sign transformer, and another kind is the electronic type gas tube sign transformer.The former reliability is higher relatively, therefore be widely adopted, yet since its move at low power factor, so self inefficiency, consumes energy is relatively large.In addition, this kind transformer secondary output services voltage under long-term high effect of electric field, easily produces corona the aging coil partial discharge that causes of insulating material is punctured like this up to 15KV in the casing; And the latter developed in recent years and put goods on the market, because it mainly is made of electronic devices and components, the long-time running failure rate is higher under the environment poor condition, was therefore seldom adopted by the user.
In view of the foregoing, the purpose of this utility model provides the reliable and energy-conservation gas tube sign transformer of a kind of long-time running.
The purpose of this utility model is to realize like this; it comprises casing and is located at the electromagnetic type transformer that is made of iron core, low pressure line chart and high-tension coil in this casing, it is characterized in that: the protector that also is provided with the power-factor compensator that is made of bucking coil and capacitor and is made of the piezo-resistance that bidirectional diode reaches and high-tension coil is in parallel that is in parallel with low-voltage coil at step down side.
In order to prevent in casing, to produce corona phenomenon, also can be provided with the anti-corona square ring of shielding high-tension coil.
The utility model has been owing to set up power-factor compensator, thereby improved power factor, reduces reactive loss, transformer self operating efficiency obviously improved, thereby reached purpose of energy saving; Increase protection link and corona protected technique measure, thereby improved unfailing performance.
Below in conjunction with accompanying drawing the utility model is done with explanation.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model electrical schematic diagram.
By accompanying drawing as can be known, the utility model is mainly by casing 11 with place electromagnetic type transformer in this casing and power-factor compensator, protector constitute.The electromagnetic type transformer is made of iron core 4, low-voltage coil 5, high-tension coil 8; Power-factor compensator is made of bucking coil 15 that places step down side and capacitor 13, and the capacitance of adjusting capacitor can reach the purpose that improves power factor; Protector is by bidirectional diode 12, piezo-resistance 16 constitutes, bidirectional diode 12 is in parallel with low-voltage coil 5, its effect is to prevent that line voltage from impacting the generation spike, conducting principle by bidirectional diode is protected, and the piezo-resistance 16 that is in parallel with high-tension coil 8 is mainly used in when electrical network impact or second open circuit, causes that secondary output is too high, by this piezo-resistance output voltage is controlled, the electric elements of protector place on the interior printed substrate 9 of casing; Be shielded from 14 balanced electric fields of anti-corona square ring of high-tension coil, prevent that corona phenomenon from the aging puncture of insulating material taking place, causing, can improve reliability greatly, sequence number 1 and 10 in the accompanying drawing is respectively low pressure porcelain vase and high-tension porcelain insulator, sequence number 2 and 7 is respectively insulation pitch prill and insulating board, sequence number 3 is an earth stud, and sequence number 6 is the magnetic shunt iron core.
