Abstract
A lightning protection transformer adopts the structure that a ceramic air discharge tube is connected in parallel with two ends of the primary coil of a medium and small sized transformer, which are connected with a 220V power supply. When encountering thunder and lightning (induction stroke), the discharge tube is conducted; and after the thunder and lightning, the discharge tube returns to a turn-off state, so as to protect the primary coil of the transformer.
Description
Affiliated technical field:
The utility model relates to a kind of novel transformer, is mainly used in middle-size and small-size transformer, makes it avoid being smashed when running into thunder and lightning (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 input 220V power supply, primary coil does not all have lightning protection device, is not enough, is easy to be smashed by thunder and lightning.A lot of middle-size and small-size transformers (as: cable TV centrally connected power supply power supply box) are arranged; be installed in open-air, open-air and the 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, causes the damage of 90% above transformer all to occur in primary coil; add that this lightning protection device just can effectively protect primary coil, reduce the loss.
Summary of the invention:
In order to prevent the destruction of thunder and lightning centering miniature transformer primary coil.
The technical scheme that the utility model adopted is: in two terminations that middle-size and small-size transformer and 220V power supply join and connect a ceramic air discharge tube, under the pottery air discharge tube normal voltage, resistance is in open circuit greater than 1,000 ten thousand ohm, not to any influence of various parameter generating of transformer.When transformer meets with thunder and lightning (induction thunder) when being far longer than 220 volts voltage; pottery air discharge tube work: short circuit; make the blowout on the 220V power path; the air switch tripping operation; after the thunder and lightning, ceramic air discharge tube recovers normal condition (disconnection), thereby has effectively protected primary coil; only need to change fuse; after recovering the air switch on the 220V power path, transformer still can operate as normal, has avoided loss; the pottery air discharge tube can repeatedly use; need not each replacing, safe and reliable, the life-span is long (more than 10 years; even discharge tube lost efficacy, also can not influence the parameter and the use of transformer).
The beneficial effects of the utility model are: make middle-size and small-size transformer suffer thunderbolt (induction thunder), exempt from during the high pressure surge to be smashed, and discharge tube installed easily, economy, and safe and reliable, can be repeatedly used the life-span long (more than 10 years).
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 a lightning protection transformer.
In figure (1) (2), 1,220V power line 2, fuse 3, ceramic air discharge tube 4, transformer 5, (silicon steel sheet) 6 unshakable in one's determination, transformer secondary output coil
Embodiment:
Extremely ceramic air discharge tube (generally with conducting voltage more than 600 volts) is attempted by on transformer and the termination that the 220V power supply is connected with one two in figure (1) (2).For convenience, ceramic air discharge tube can be packaged in transformer coil surface and silicon steel sheet intersection.
Claims (1)
1. lightning protection transformer is characterized in that: the two ends of joining at the primary coil and the 220V power supply of middle-size and small-size transformer also connects a ceramic air discharge tube.
