Abstract
The utility model relates to power system high-voltage measuring equipment, in particular to a combined transformer mainly comprising a porcelain bottle, a cover plate, an oil tank, a voltage transformer and a current transformer. The porcelain bottle is arranged on the cover plate, and the voltage transformer and the current transformer are electrically connected with the porcelain bottle, are arranged in the oil tank and are fixed above the cover plate through a hanging plate and stud bolts. The utility model has the advantages of simple structure, time saving and convenient maintenance, and the like; and a high-voltage power metering box can be formed by connecting secondary connecting contact terminals with an electric energy meter.
Description
Technical field:
The utility model relates to electric power system high-tension measurement equipment, specifically a kind of combination transformer.
Background technology:
Combination transformer is the equipment of measuring voltage, electric current, electric energy in electric power system or the electric control system.The oil immersed type combination transformer mainly is made up of porcelain vase, fuel tank, voltage transformer summation current transformer, and the voltage transformer summation current transformer is electrically connected with porcelain vase.Usually the voltage transformer summation current transformer is installed in the fuel tank bottom, and its shortcoming is: during the maintenance of voltage transformer summation current transformer, need the oil in the first off-loading, hang out the voltage transformer summation current transformer again and overhaul, both took a lot of work, and inconvenient again.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of existing oil immersed type combination transformer, and a kind of maintenance saving of labor is provided combination transformer easily again.
The utility model, comprise porcelain vase, cover plate, fuel tank, voltage transformer summation current transformer, the porcelain vase installing on the cover board, the voltage transformer summation current transformer is electrically connected and places fuel tank with porcelain vase, the voltage transformer summation current transformer is fixed on the cover plate of fuel tank top by boatswain chair and double-screw bolt.
The utility model is provided with respirator on described cover plate, the secondary connection post also is provided with on the cover board.
The utility model, have simple in structure, safeguard the characteristics such as convenient that save time, its secondary connection post with just constitute a high-voltage power metering case after electric energy meter is connected.
Description of drawings:
Fig. 1 is the electrical schematic diagram of embodiment.
Fig. 2, Fig. 3 are the structural representation of embodiment.
Among the figure, 1, porcelain vase 2, cover plate 3, fuel tank 4, double-screw bolt 5, voltage transformer 6, current transformer 7, boatswain chair 8, dehydrating breather A1, B1, C1 be that high pressure input connecting line A2, B2, C2 are that high pressure output connecting line a, b, c, n are that secondary output line k1A, k1B, k1C, the k2 of voltage transformer is the secondary output line of current transformer.
Embodiment:
See figures.1.and.2, this combination transformer, comprise porcelain vase 1, cover plate 2, fuel tank 3, voltage transformer 5 summation current transformers 6, porcelain vase 1 is installed on the cover plate 2, voltage transformer 5 summation current transformers 6 are electrically connected and place fuel tank with porcelain vase 1, and voltage transformer 5 summation current transformers 6 are fixed on the cover plate 2 of fuel tank 3 tops by boatswain chair 7 and double-screw bolt 4.Be provided with respirator 8 on described cover plate 2, the secondary connection post of voltage transformer 5 summation current transformers 6 also is provided with on the cover board.
This combination transformer belongs to the oil immersed type instrument transformer, iron core adopts the high silicon steel sheet closed assembly of high-quality cold-rolled orientation to form, the iron core of single-phase composite type voltage instrument transformer is a shell type, and the three-phase three-limb voltage transformer adopts three-phase closed assembly three pillar type structure, and current transformer adopts shell type.Voltage transformer, current mutual inductor coil adopt enamelled wire, the coiling of silk-covered wire material to form.Because the voltage and current instrument transformer is fixed on the tank cover 2 by boatswain chair 7 and double-screw bolt 4 respectively, the holding screw of removing cable link and case edge can hang out fuel tank together with voltage transformer, current transformer, be convenient to install or maintenance, fuel tank internal is equipped with transformer oil.Secondary connection post and high voltage porcelain bushing Guan Jun draw on case lid, have pouring orifice, respirator or oil conservator on the case lid simultaneously.Instrument box is equipped with in the casing front, and one of two of mechanical power energy meters or electronic electric energy meter can be installed in the instrument box, and one of wiring testing terminal row is arranged.The secondary connection post of combination transformer with just constitute a high-voltage power metering case after electric energy meter is connected.Instrument box can according to user's needs make supporting at random or split supporting, electric energy meter also can be according to user's needs apolegamy in the case.
