Abstract
The utility model belongs to a high-voltage electrical device, particularly a dry high-voltage current transformer, which is used in current measurement and protection in 35KV and above grid and includes a primary electrical conductor, an insulating winding layer, a secondary winding, a case body, a wire connecting terminator, an external insulation, a bottom platform and a connector. The insulating winding layer is directly wound on the periphery lateral side of the primary electrical conductor, saving raw material and reducing cost.
Description
Technical field
The utility model belongs to a kind of High-Voltage Electrical Appliances device, particularly a kind of Dry Type High Tension Current Transformer that is used for 35KV and above electrical network current measurement and protection.
Background technology
At present, the Dry Type High Tension Current Transformer that has a kind of interior external insulation to make on the market for the organic synthesis material, its structure is that a winding passes the endoporus of the tubulose rigid backbone of being made by non-magnet_conductible material, the tubulose rigid backbone alternately holds insulating barrier outward.Because the current transformer insulating bag of this kind structure is to surround on the tubulose rigid backbone around layer, and insulating bag is increased around layer materials, causes raw-material waste.
Summary of the invention
The purpose of this utility model provides and does not a kind ofly contain U type tubulose rigid backbone, saves raw-material Dry Type High Tension Current Transformer.
The utility model is to realize like this, comprise that Primary Conductor, insulating bag are around layer, secondary winding, casing, binding post, external insulation, base frame and connector, secondary winding places insulating bag around the ground of layer screen part, and fix with casing and external insulation, comprise that also insulating bag directly surrounds the periphery outside of Primary Conductor around layer.Primary Conductor can be bar-shaped, also can be tubulose, can also be to add in the tubulose to wear conductor structure; Connector can be a solid construction, also can be hollow-core construction.
The utility model has the advantages that the U type tubulose rigid backbone of having saved in the existing Dry Type High Tension Current Transformer, insulating bag directly surrounds the Primary Conductor periphery outside around layer, has saved raw material, has reduced the cost of product.
