Abstract
The utility model relates to an electric device, more specifically a lightning protection isolation transformer, which is composed of an iron core column, a primary coil, a secondary coil, a shielding layer and an insulator, wherein, the primary coil and the secondary coil group are combined and positioned on the same iron core column, and the shielding layer and the insulator are arranged between the coils. The utility model has the advantages of simple structure, good lightning protection effect, etc.
Description
The utility model relates to a kind of electrical installation, specifically a kind of isolating transformer with lightning protection effect.
In the prior art, Chinese patent discloses the transformer that the patent No. is 87214953 the stable output of voltage, its principle is the A.C. contactor in the output termination one usefulness electro-magnetic screen layer shielding of transformer, the moved end of contactor connects a trace, and the number of turn of transformer output coil is greater than the former number of turn of appraising and deciding.On the coil of transformer output, put a metal movable contact, the trace of an edge joint contactor moved end, the spring of another edge joint one fixed-site.Its weak point is complex structure, and lightning protection effect is poor.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of isolating transformer with good lightning protection effect is provided.
To achieve these goals, the utility model provides a kind of new technical solution: this lightning protection isolating transformer is made up of iron core column, primary coil, secondary coil, screen and insulator, primary coil, the combination of secondary coil group place with on the iron core column, are provided with between the coil and screen and insulator.
The utlity model has advantages such as simple in structure, that lightning protection effect is good.
Accompanying drawing is embodiment of the present utility model.
It among the figure structural representation of the present utility model.
Below in conjunction with accompanying drawing and concrete execution mode essentiality content of the present utility model is described in further detail.
This lightning protection isolating transformer is made up of iron core column (1), primary coil (2), secondary coil (3), screen (4) and insulator (5), primary coil (2), secondary coil group (3) combination place on the same iron core column (1), are provided with between the coil and screen (4) and insulator (5).This isolating transformer that utilizes the capable wave reflection principle design of electromagnetic field to go out has complete wave reflection effect to the circuit direct lightning strike, for direct lightning strike the equipotential effect is arranged, and can eliminate the generation of " counterattack ".
Claims (1)
1. lightning protection isolating transformer, form by iron core column (1), primary coil (2), secondary coil (3), screen (4) and insulator (5), it is characterized in that: primary coil (2), secondary coil group (3) combination place on the same iron core column (1), are provided with between the coil and screen (4) and insulator (5).
