Abstract
Provided is a transformer for preventing inductive thunders. A ceramic gas discharge tube with 800V conduct voltage is connected with two terminals which are formed by the connections between a small and medium sized transformer primary coil and a 220V power supply. The discharge tube is conducted when meets inductive thunders and is recovered to the normal disconnected state when the inductive thunders disappear, thereby leading the primary coil of the small and medium sized transformer to be protected.
Description
Affiliated technical field:
The utility model relates to a kind of novel anti-induction thunder transformer, is mainly used in middle-size and small-size transformer, makes it avoid being smashed when running into the induction thunder, behind the replacing main fuse, still can normally use.
Background technology:
Existing middle-size and small-size 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 not enough, is easy to be smashed by thunder and lightning.Have that a lot of middle-size and small-size transformers (as: cable TV centrally connected power supply power supply box) are installed in the open, the open-air and various household electrical appliances in the minefield; the probability that meets with the induction thunder is very high; the space of transformer is limited; and consider cost; primary coil enamelled wire (copper cash) is much thinner than secondary coil; cause the damage of middle-size and small-size transformer more than 90% 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 to respond to the destruction of thunder centering miniature transformer primary coil.
The technical scheme that the utility model adopted is: at two terminations that middle-size and small-size transformer 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 to any influence of various parameter generating of transformer.When transformer meets with the induction thunder; induction lightening is pressed generally and all extremely several ten thousand is being lied prostrate more than 1 kilovolt; pottery air discharge tube work: discharge short; electric current is without the primary coil of transformer; make 220 volts of blowouts on the power path; the air switch tripping operation, after the thunder and lightning, ceramic air discharge tube recovers normal open-circuit condition; also can do with the high pressure surge that voltage is higher than 800 volts; thereby effectively protected the primary coil of transformer, only needed to change fuse, recover the air switch on 220 volts of power paths after; transformer still can operate as normal; avoided loss, ceramic air discharge tube can repeatedly use, and need not each replacing; safe and reliable; life-span is long, even lost efficacy, also can not influence the parameter and the use of transformer.
The beneficial effects of the utility model: exempt to be smashed when making middle-size and small-size transformer suffer from the induction thunder, and discharge tube is installed easily, economy, safe and reliable, can be repeatedly used.
Description of drawings:
Below in conjunction with accompanying drawing and example, the utility model is further specified:
Figure (1) is circuit theory diagrams of the present utility model.
Figure (2) is an anti-induction thunder transformer.
In figure (1) (2), 1,220 volt power line 2, fuse 3,800 volts of ceramic air discharge tubes 4 of conducting voltage, transformer 5, iron core (silicon steel sheet) 6, transformer secondary output coil
Embodiment:
On the primary coil that in figure (1) (2), is attempted by middle-size and small-size transformer and two terminations that 220 volts of power supplys are connected with two extremely ceramic air discharge tubes of 800 volts of conducting voltage.For convenience, 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 middle-size and small-size transformer and 220 volts of power supplys join and the ceramic air discharge tube that connects 800 volts of conducting voltage.
