Full-sealed side wire outlet type amorphous alloy transformer

Abstract

The invention relates to a full-sealed side wire outlet type amorphous alloy transformer, and belongs to the technical field of transformer manufacture. The invention adopts the technical scheme that: (1) a high voltage side sleeve of the transformer is changed into a special sleeve for an American-type transformer; by adopting a structural form of sequentially matching and connecting an elbow type cable joint, a single-through sleeve and a sleeve seat, all joints of high voltage cables are prevented from leaking, and the safety of the high voltage sleeve of the transformer is improved; high voltage wire connection and overhauling and change of the sleeve of the transformer are more convenient; and (2) a container type current transformer 5 of three phases a, b and c is assembled below the low voltage side sleeve, the current transformer can transform the current flowing through a low voltage cable and transmit the transformed current to a control room of a power department, and the transformed current is converted into electric quantity data for directly reading a low voltage, so that the accuracy of electric quantity statistics of the transformer is ensured; and the external current transformer is convenient to overhaul and easy to replace. According to the invention, on the premise of ensuring the performance of the transformer, the use problem of the amorphous alloy transformer under the open air environment is solved, the energy saving and emission reducing requirements of the power department are met, the service life of the transformer is prolonged, and the safety of the transformer is improved.

Description

Technical field: [0001] The invention relates to a fully sealed side outlet type amorphous alloy transformer, which belongs to the technical field of transformer manufacturing. Background technique: [0002] At present, there are a large number of distribution transformers in rural power grids and urban power grids in my country, and most of them are installed in outdoor open-air environments. After the high and low voltage terminals of transformers are soaked by rain and snow, the performance of transformers will be affected. And if there is an electric leakage, there will be a large potential safety hazard, which will bring great losses to the family and the national power sector. Amorphous alloy distribution transformer uses a new type of material—amorphous alloy strip as the transformer core material. The no-load loss of the transformer is low, which is equivalent to about 25% of the same capacity S9 type silicon steel sheet core distribution transformer. The energy-sav...
