Abstract
A fully-closed type epoxy resin-cast current transformer comprises a cast body, an iron core, a primary winding, a secondary winding, a primary wiring inlet terminal and a primary wiring outlet terminal; a secondary winding connecting terminal block is arranged at the lower part of the cast body, the iron core is positioned at the middle part of the cast body, the secondary winding is wound on the iron core, and a mounting baseplate is arranged at the bottom end of the cast body; the a primary wiring inlet terminal and the primary wiring outlet terminal are arranged at the top of the cast body and are respectively fixedly connected with two ends of the primary winding correspondingly, and the primary winding penetrates through a center hole of the iron core. The cast body, the iron core, the primary winding, the secondary winding, the primary wiring inlet terminal, the primary wiring outlet terminal and the secondary winding terminal block are cast into an integrated structure. The fully-closed type epoxy resin-cast current transformer has the advantages of scientific and reasonable design, originality, stable performance, reliable operation, super practicability and advancement, convenient installation, simple operation and low operating cost, thereby suiting the use of electric power maintenance in the transformer production industry.
Description
Technical field
The utility model relates to current transformer, what be specifically related to is the current transformer of 20KV totally enclosed type poured with epoxy resin.
Background technology
Electric high-tension switch cabinet is adopted the 20KV switch cubicle day by day, the advantage that it is many has for example increased insulation property greatly, and volume is little, maintenance is few, yet present monitoring current Control current etc. need be used a plurality of current values simultaneously, has no alternative and have to adopt a plurality of current transformers to combine, and the obvious floor space of such combination is huge, the equipment that uses is just many, the investment funds are more, and maintenance on ordinary days is also big, and operation cost is just high naturally.
At the problem of above-mentioned existence, the professional person takes measures to solve this fundamental issue by every means.Yet in the whole bag of tricks on probation, exist separately shortcoming and problem, such as the scheme complexity, the components and parts of use are more, cause virtually installation, the operation all comparatively bothersome, cost is also high naturally, weighs the advantages and disadvantages, and these methods on probation all are not suitable for promoting the use of in practical power systems.
The utility model content
The purpose of this utility model is to have above-mentioned problems at the current transformer that present cabinet uses, and provides a kind of easy to install, does not have the current transformer of the totally enclosed type poured with epoxy resin of maintenance.
The technical scheme that adopts is:
The current transformer of totally enclosed type poured with epoxy resin comprises pour mass, iron core, winding, secondary winding and a primary connection end; The bottom of described pour mass is provided with secondary winding binding post box, and the two ends of secondary winding are connected with corresponding terminal in the secondary winding binding post box respectively.Iron core is positioned at the middle part of pour mass, and secondary winding is wrapped on the iron core, and iron core adopts two C shape iron core butt joints to be circular ring type; The bottom of pour mass is provided with the installation base plate; Its design feature is:
The top of above-mentioned pour mass is provided with the primary connection inlet side and primary connection goes out end, and described primary connection is corresponding fixedly connected with the two ends of a winding respectively into and out of end, and a winding wears the centre bore of iron core.
Above-mentioned pour mass, iron core, winding, secondary winding, a primary connection are cast for an overall structure into and out of end and secondary winding binding post box.
Principle of the present utility model and characteristics:
Operation principle of the present utility model is identical mutually with the operation principle of known current transformer, is characterized in:
The utility model has increased layer insulation thickness, and product anti overvoltage ability is strengthened.
Adopt a winding to wear iron core and secondary winding, the structure that pours into an integrated entity improves dielectric strength greatly, has strengthened fail safe and reliability, improves the precision of monitoring, metering.The circular ring type iron core of high-quality substitutes laminated core, and the no-load loss and the no-load current of iron core are all little, has improved the carrying load ability of product, has also improved operating efficiency simultaneously.
The utility model safety, environmental protection, operation is got up reliable and stable.
Adopt overall construction design, volume is little, and is in light weight, dwindled the occupation of land space, and daily need not the maintenance installed in the suitable 24KV switch cubicle.
Current transformer of the present utility model is excellent performance but also take up an area of for a short time not only, has immeasurable value to saving limited land resources, is renewal product of new generation, and it is the key equipment of control and instrument demonstration.
The utility model design science, reasonable, original, stable performance, reliable has extremely strong practicality and advance, and is easy for installation, simple to operate, operation cost is low, and suitable instrument transformer production industry and power department use.
