Abstract

The utility model relates to a dry transformer, in particular to a radiation dry transformer with zero discharge. The dry transformer adopts the technical proposal that the interior of the dry transformer consists essentially of an iron core of the transformer, a low-voltage coil and a high-voltage coil, wherein, the low-voltage coil is connected with the heat absorption end of a heat pipe and the radiation end of the heat pipe is connected with a radiator at the exterior of the transformer. Compared with the prior art, the dry transformer has the beneficial effects that: firstly, a cooling fan is eliminated, which has effect on saving electricity and improves the level of safe operation; secondly, as internal temperature of the transformer can be effectively lowered, the capacity of the transformer can be promoted or the section of lead wires for the coils can be reduced when in the same capacity, thus achieving the purpose of saving the manufacturing cost of copper material.

Description

Zero-emission heat radiating type dry-type transformer

One, technical field:

The utility model relates to a kind of dry-type transformer, particularly relates to a kind of zero-emission heat radiating type dry-type transformer.

Two, background technology:

At present, in transformer, because coil, iron core produces a large amount of heats, causes the rising of transformer temperature, temperature raises thermal resistance and resistance is increased, can aggravate the further rising of temperature again, overheated for a long time, increased energy loss, make simultaneously insulation accelerated wearing out again, reduce this equipment safety operation level., in common transformer, how to cool off, in time the discharge section heat with cooling fluid (transformer oil) for this reason, in dry-type transformer, there is not cooling fluid, so it is only in manufacturing process, strengthen the winding wire cross section, increase iron core, low-voltage coil, the distance that high-tension coil is mutual, externally dispose simultaneously blower fan and force cooling, so promptly waste material, wasted electric energy again, also reduced the reliability of equipment safety operation simultaneously.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of and increased safety operation level, effectively reduces the zero-emission heat radiating type dry-type transformer of transformer internal temperature.

Its technical scheme is: inside mainly is made up of transformer core, low-voltage coil and high-tension coil, and low-voltage coil is connected with the heat absorbing end of heat pipe, and the radiating end of heat pipe is connected with the radiator of transformer outside.

Preferable technical scheme is: connect the heat absorbing end of heat pipe on the zero line of low-voltage coil, heat pipe causes the top of transformer core along zero-emission, and the radiating end of heat pipe is connected with the radiator of transformer outside.

The utility model compared with prior art has following beneficial effect:

The one, remove cooling blower and played power savings, increased safety operation level, the disposable input of the present invention is little;

The 2nd, owing to can effectively reduce the transformer internal temperature, therefore can improve the capacity of transformer, or when same capability, can suitably reduce the winding wire cross section, reach and save the purpose that copper material reduces cost.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is vertical views of the present utility model.

Five, embodiment:

Dry-type transformer inside mainly is made up of transformer core 1, low-voltage coil 2 and high-tension coil 3 etc., the heat absorbing end that on the zero line 6 of low-voltage coil 2, connects heat pipe 4, heat pipe 4 causes the top of transformer core 1 along zero-emission, and the radiating end of heat pipe is connected with the radiator 5 of transformer outside, low-voltage coil and part iron core heat are by the heat absorption of heat pipe heat absorbing end like this, drain into along zero line on the radiator of transformer outside and dispel the heat

In dry-type transformer, iron core and low-voltage coil are positioned at the innermost layer of equipment, are the poorest positions of radiating condition, start with in the poorest position of slave unit radiating condition of the present invention, adopt hot pipe technique, utilize to do become zero line and the equipotential characteristics of the earth, in time discharge internal heat, thereby be implemented in safe in the charging equipment, reliably, continuously internal heat is discharged, removed cooling fan, easy again operational management has realized economize on electricity, purpose of energy saving.
