Abstract
A distribution transformer comprises high voltage and low voltage coils arranged in an oil tank, and a high voltage lead and a low voltage lead are arranged outside the oil tank. A current transformer is set in the distribution transformer in advance on a portion where the low voltage lead is located inside or outside the oil tank. The current transformer is set inside the distribution transformer in advance so that data sampling can be provided for reactive compensation, a transformer terminal unit (TTU) or remote metering and remote control of the distribution transformer. Compared with the traditional distribution transformer, when a reactive compensation device and a TTU device are installed, no captive test (CT) box is needed to be additionally installed on a circuit, thereby simplifying wiring and improving reliability. The distribution transformer is simple and reasonable in structure and strong in applicability, and facilitates future wiring.
Description
Technical field
The utility model relates to a kind of distribution transformer, particularly a kind of oil immersion-type distribution transformer.
Background technology
Chinese patent document number CN201215755 discloses a kind of oil immersion-type distribution transformer on April 1st, 2009; It includes fuel tank, case lid, iron core, high and low pressure coil, and fuel tank places on the base, and high-voltage connection with well and low-voltage lead with well are housed respectively on the case lid of fuel tank; High-voltage connection links to each other with the output of high-tension coil and low-voltage coil respectively with low-voltage lead; The device body insulation of immersing transformer oil is housed in the fuel tank of case lid bottom, and fuel tank is equipped with the ripple radiator outward, and said device body insulation is to have installed around low, high-tension coil on the iron core from inside to outside; There is core insulation at the iron core two ends; And be fixed together through pressing plate, between iron core and low-voltage coil winding fagging and cardboard are arranged, between high-tension coil and low-voltage coil corrugated board is arranged; Phase partition is arranged between high-tension coil, and constituting transformer core is three-phase three-column Pyatyi seam step structure.The transformer of this structure when reactive power compensator or TTU device are installed, need be on low-voltage lead extra connection current transformer, increased the difficulty of wiring.
The utility model content
The purpose of the utility model aims to provide a kind of simple and reasonable, convenient wiring in the future, distribution transformer that applicability is strong, to overcome weak point of the prior art.
A kind of distribution transformer by this purpose design comprises the high-voltage coil and low-voltage coil that is arranged in the fuel tank, and fuel tank is outside equipped with high-voltage connection and low-voltage lead; Its architectural feature is that distribution transformer is provided with current transformer in advance.
Said current transformer is arranged on the low-voltage lead.
Said current transformer is arranged on low-voltage lead in advance and is positioned on fuel tank or the outer position.Wherein, current transformer preferably is arranged on fuel tank internal, the transformer outward appearance is not brought influence, simultaneously, also can bring better protection for current transformer.
The utility model is the integrated in advance current transformer of having installed in transformer inside, can data sampling be provided for reactive power compensation, TTU (distribution transformer monitoring terminal) or the remote measuring and controlling of distribution transformer.With traditional distribution transformer relatively: when reactive power compensator, TTU device are installed, do not need to install additional more on the line the CT case, simple wiring has improved reliability.It is simple and reasonable, convenient wiring in the future, applicability are strong.
