Abstract
The invention discloses an anti-inductive-thunder transformer. A ceramic air discharge tube with break-over voltage 800 volts is connected with two endpoints in parallel, wherein the endpoints are formed by connecting of a small and medium size transformer primary coil and a power source with 220 volts. When inductive thunders happen, the discharge tube is conducted. When the inductive thunders disappear, the discharge tube returns back to a normal off state. Therefore, the primary coil of a small and medium size transformer is protected.
Description
Affiliated technical field:
The present invention relates to a kind of anti-induction thunder transformer, be mainly used in Transformer, can avoid being smashed when running into the induction thunder, after changing main fuse, still can normally use.
Background technology:
Existing Transformer only is equipped with fuse in the live wire of 220 volts of power supplys of input, primary coil does not all have anti-induction thunder device, is inadequate, is easy to be smashed by thunder and lightning.There are a lot of Transformers (as: cable TV centrally connected power supply power supply box) to be arranged on outdoor, open-air and the various household electrical appliances in the minefield; the probability that meets with the induction thunder is very high; the limited space of transformer; and consider cost; primary coil enamelled wire (copper cash) is much thinner than secondary coil; cause the damage of 90% above Transformer all to occur in primary coil, add that this lightning protection device can effectively protect primary coil, reduce the loss.
Summary of the invention:
In order to prevent responding to thunder to the destruction of Transformer primary coil.
The technical solution adopted in the present invention is: at two terminations that Transformer primary coil and 220 volts of power supplys join and the ceramic air discharge tube that connects 800 volts of conducting voltage, the pottery air discharge tube is under normal voltage, resistance is in open-circuit condition greater than 1,000 ten thousand ohm, not on any impact of various parameter generating of transformer.when transformer meets with the induction thunder, induction lightening press generally all more than 1 kilovolt to several ten thousand volts, pottery air discharge tube work: discharge short, electric current is without the primary coil of transformer, make 220 volts of blowouts on power path, the air switch tripping operation, after thunder and lightning, the pottery air discharge tube recovers normal open-circuit condition, also can do with voltage higher than the high-voltage surge of 800 volts, thereby effectively protected the primary coil of transformer, only need to change fuse, after recovering 220 volts of air switches on power path, transformer still can work, avoided loss, the pottery air discharge tube can repeatedly use, need not each replacing, safe and reliable, life-span is long, even lost efficacy, also can not affect parameter and the use of transformer.
Beneficial effect of the present invention: exempt to be smashed when making Transformer suffer from the induction thunder, and discharge tube is easily installed, economy, safe and reliable, can be repeatedly used.
Description of drawings:
Below in conjunction with accompanying drawing and example, the present invention is further described:
Figure (1) is circuit theory diagrams of the present invention.
Figure (2) is anti-induction thunder transformer.
In figure (1) (2), 1,220 volt of power line 2, fuse 3,800 volts of pottery air discharge tubes 4 of conducting voltage, transformer 5, (silicon steel sheet) 6 unshakable in one's determination, transformer secondary output coil
Embodiment:
On the primary coil that is attempted by Transformer in figure (1) (2) with two extremely ceramic air discharge tubes of 800 volts of conducting voltage and two terminations that 220 volts of power supplys are connected.For convenient, ceramic discharge tube can be packaged in transformer coil surface and silicon steel sheet intersection.
Claims (1)
1. anti-induction thunder transformer is characterized in that: at two terminations that the primary coil of Transformer and 220 volts of power supplys join and the ceramic air discharge tube that connects 800 volts of conducting voltage.
