Abstract
The utility model provides a JDZXF-35 voltage transformer dedicated for an air charging cabinet. One end of a primary winding is connected with a corresponding connection terminal of a lower terminal box arranged at the lower part of a housing through a lead wire, and the other end of the primary winding is connected with a conducting rod arranged at the center of an elbow wire holder; the two ends of a secondary winding are respectively connected with the corresponding connection terminal of the lower terminal box through lead wires; the primary and the secondary windings are correspondingly positioned on the inner layer and the outer layer of an iron core respectively and coaxially wound around the iron core; a casting body is arranged in the housing which is an aluminum-made protective cover; and the housing, the casting body, the iron core, and the primary and the secondary windings form an integral structure; and the iron core adopting two butt joint C-shaped ion cores is mouth-shaped. The voltage transformer has the advantages of technological, reasonable and creative design, steady performance, reliable working, high practicality, high progressiveness, convenient installation, simple operation and low operation cost, and is suitable for being used in the transformer production industry and the electric power maintenance industry.
Description
Technical field
The utility model relates to voltage transformer, what be specifically related to is the voltage transformer of making for gas-filled type switch cubicle specialized designs.
Background technology
The gas-filled type switch cubicle is the novel device that power supply specialty at present adopts, the gas-filled type switch cubicle has plurality of advantages, insulation property have for example been increased greatly, the volume of cabinet is small and exquisite, maintenance is few, so the gas-filled type switch cubicle more and more is used, yet the gas-filled type switch cubicle internally technical performance of the electric component of dress has higher requirement, the dielectric strength of the voltage transformer that common switch cubicle uses, seal degree and disposablely patch the first-class requirement of making switch cubicle that all do not conform with that is to say that the voltage transformer that is installed in the gas-filled type switch cubicle needs specialized designs and making.
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.
Summary of the invention
The purpose of this utility model is that the voltage transformer volume that uses at present gas-filled type switch cubicle is big, and problems such as trouble are installed, and provides a kind of anti overvoltage ability JDZXF-35 type inflation cabinet dedicated potential transformer strong, easy to install.
The technical scheme that adopts is:
JDZXF-35 type inflation cabinet dedicated potential transformer comprises elbow junction block, shell and is contained in pour mass in the shell, iron core, winding and secondary winding; One end of a described winding is connected by the corresponding wiring terminal of lead-in wire with the lower terminal box of outer casing underpart setting, and the two ends of secondary winding are connected with the corresponding wiring terminal of lower terminal box respectively by lead-in wire; Winding and secondary winding correspondence respectively are positioned at nexine and outer and coaxial being wrapped on the iron core; Its design feature is:
The center of described elbow junction block is provided with conducting rod, and conducting rod is connected with the other end of a winding by lead-in wire;
Described shell is the aluminum protective case, is provided with pour mass in the aluminum protective case.
Above-mentioned shell, pour mass, iron core, winding and secondary winding are structure as a whole.
Above-mentioned iron core adopts two C shape iron core butt joints to be hollow.
Principle of the present utility model and characteristics:
Operation principle of the present utility model is identical mutually with the operation principle of known single-phase potential transformer, is characterized in:
The utility model has increased layer insulation thickness, and product anti overvoltage ability is strengthened.
The elbow-shaped inserting/pulling type cable joint that the utility model adopts is the plug-in termination head of all insulation, hermetically sealed, full-shield, and its rated current is big.
Adopt two C shape iron core butt joints of high-quality to be the alternative laminated core of port type iron core, the no-load loss and the no-load current of iron core are all little, have improved the carrying load ability of product, have also improved operating efficiency simultaneously.
Increased the surface creepage distance of product, product has reached iv level gradation for surface pollution, safety, environmental protection, and 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, is easy to the installation of any direction.
The utility model is widely used in the subway project in the 35KV inflating switch cabinet, the high pressure connected mode is that elbow plug hair style, shell are the aluminum protective case, having advantages such as volume is little, in light weight, is the voltage transformer that designs for the gas-filled type switch cubicle specially, is renewal product of new generation.
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 electric power maintenance are used.
