Abstract
The invention relates to the field of transformers, in particular to a fully-enclosed cast post-combined voltage transformer, which consists of a high-voltage contact, a high-voltage fuse, a high-voltage lead terminal, a high-voltage coil, a low-voltage coil, an iron core and an installation plate, wherein the two ends of the high-voltage fuse are respectively connected with the high-voltage contact and the high-voltage lead terminal, the high-voltage lead terminal is connected with the high-voltage coil, the iron core is arranged between the high-voltage coil and the low-voltage coil, and the lower end of the iron core is fixed with the installation plate. The fully-enclosed cast post-combined voltage transformer has the advantages that: 1) the iron core of the transformer is in a ring structure and is made of a high-quality cold-rolled steel sheet in a rolling way, and primary windings are fully insulated; and 2) since the transformer is provided with the fuse and the integrated design is adopted, the safety performance of the transformer is improved, the cost is not increased and the cost performance is high; and the internal space of the transformer is used in a more rationalized and standardized way.
Description
Technical field
The present invention relates to the instrument transformer field, concretely, relate to a kind of totally-enclosed cast back composite type voltage instrument transformer.
Background technology
Insulation mode can be divided into dry type, cast-type, oil immersed type and gas-filled type, dry type soak the insulating cement voltage transformer simple in structure, do not have and to catch fire and explosion hazard, but dielectric strength is lower, only is applicable to the indoor type device below the 6kV; Cast-type voltage transformer compact conformation, easy to maintenance is applicable to 3kV～35kV indoor type power distribution equipment; Oil immersed type voltage transformer insulation property are better, can be used for the above outdoor type power distribution equipment of 10kV; The gas-filled type voltage transformer is used for the totally-enclosed electrical equipment of SF6.
The impedance of voltage transformer itself is very little, in case secondary is short-circuited, electric current burns coil with sharp increase.For this reason, the former edge joint of voltage transformer has fuse, the secondary reliable ground, in order to avoid former and deputy limit when damage insulation, secondary high potential occurs over the ground and causes the person and equipment breakdown.
Summary of the invention
The purpose of this invention is to provide a kind of totally-enclosed cast back composite type voltage instrument transformer.
Technical scheme to be solved by this invention is following: the present invention is made up of high-voltage contact, high-tension fuse, high-voltage connection terminal, high-tension coil, low-voltage coil, iron core, mounting panel; The high-tension fuse two ends connect high-voltage contact and high-voltage connection terminal, and the high-voltage connection terminal connects high-tension coil, is iron core between high-tension coil and the low-voltage coil, and the lower end has mounting panel to fix.
Described iron core is a loop configuration, is that the high-quality cold-reduced silicon sheet rolls and forms, and one time winding is all insulation.
Described totally-enclosed cast back composite type voltage instrument transformer has the fuse protection.
The totally-enclosed cast of the present invention back composite type voltage instrument transformer is applicable to and exchanges 50Hz, 60Hz that rated operational voltage is 27.5～35Kv, does voltage measurement, electric energy metrical use in the electric power system of inside plant.
The invention has the advantages that:
1, transformer iron core loop configuration adopts the high-quality cold-reduced silicon sheet to roll and forms, and one time winding is all insulation.
2, because of carrying fuse, adopt the integration design, make instrument transformer not increase cost simultaneously in the raising security performance, cost performance is high; Its inner space is used more rationalize and standardize.
