Abstract
The invention provides a triangular dry type transformer with an overhead radiator. A radiating housing is arranged on the upper part of the triangular dry type transformer; a radiating fan is arranged on the radiating housing and is fixed on the radiating housing to form a radiating assembly; the radiating assembly is fixed with an upper clamping piece of a transformer body together through a fixing piece; therefore, the radiating assembly and the transformer are connected into an integral structure. When the fan works, ascending hot airflow is forced to be exhausted by the fan through a natural air duct formed by a coil, an iron core, fittings and the like of the transformer. The radiating fan arranged on the radiating housing can be one or three axial flow fans and also can be a transverse flow fan. The triangular dry type transformer has the advantage that: the radiating effect of the triangular dry type transformer is effectively improved.
Description
Technical field:
The present invention relates to a kind of triangularity depressor, belong to field of electrical equipment, particularly a kind of triangle dry-type transformer of overhead heat radiation.
Background technology:
For helping the heat radiation of triangle dry-type transformer, existing solution is: the three-phase coil of triangle dry-type transformer is triangularly arranged, and respectively places a crossflow fan below coil.The shortcoming of the method is that the natural air channel that the air-flow guiding of crossflow fan is difficult to form with transformer coil, iron core and annex fits like a glove, and radiating effect is poor.
Summary of the invention:
The objective of the invention is to: propose a kind of triangle dry-type transformer structure of overhead heat radiation, can solve the heat dissipation problem of triangle dry-type transformer preferably.
Implementation method of the present invention is: place a cooling fan on triangle dry-type transformer top, the natural air channel that utilizes transformer coil, iron core and annex etc. to form, thermal air current is forced to discharge through blower fan, realized a kind of triangle dry-type transformer of overhead heat radiation thus.
In the present invention: a heat radiation case is set on triangle dry-type transformer top, on the heat radiation case cooling fan is installed, cooling fan is by fixture and the heat radiation case formation heat elimination assembly that is fixed together; Heat elimination assembly is fixed together by the upper clamping piece of fixture and transformer body, and heat elimination assembly and transformer body are linked to be overall structure thus.
In the present invention: the center at the heat radiation case is equipped with an axial flow blower, and axial flow blower is by fixture and the heat radiation case formation heat elimination assembly that is fixed together.
In the present invention: on the heat radiation case three axial flow blowers are installed, the fixed position of three axial flow blowers corresponds respectively to the top of transformer three-phase coil; This blower fan is fixed together with the heat radiation case respectively by fixture.
In the present invention: on the heat radiation case three crossflow fans are installed, this blower fan is fixed together with the heat radiation case respectively by fixture.
In the present invention: on a facade at heat radiation case edge; setting-in a transformer electronic protection; realization is to the real time data of the phenomenons such as overvoltage/undervoltage, overcurrent, overload and excess temperature of transformer and the protection and the record of state, and device communication interface also can pass mutually with electric network data.
The invention has the advantages that: the natural air channel that the overhead radiator structure has utilized transformer coil, iron core and annex etc. to form, the thermal air current that rises is forced to discharge through blower fan, improve the radiating effect of triangle dry-type transformer, guaranteed the safe operation of transformer.
