Abstract
The utility model discloses a handstand sulfur hexafluoride (SF6) gas insulation current transformer, which comprises a casing, a secondary winding assembly, a shielding cover, a base, a secondary outlet box, a density controller and an outdoor insulation cable, wherein the outdoor insulation cable penetrates through a primary shielding pipe and the center of the secondary winding assembly, winds on the casing and is fixed through a cable protection casing in limit mode. The handstand SF6 gas insulation current transformer adopts the outdoor insulation cable structure to replace a traditional aluminium pipe, effectively increases the number of ampere turns of products, and accordingly shortens integral size of the products and leads structures of the products to be more reasonable. The handstand SF6 gas insulation current transformer ensures product performance, simultaneously reduces product production cost, and improves product cost performance.
Description
Technical field
The utility model relates to the grid equipment field, is specifically related to a kind of inverted SF
6Gas insulated high voltage current transformer.
Background technology
Along with the development of intelligent grid construction and the carrying out of big grid interconnect, operation of power networks requires to improve constantly, and when guaranteeing system safety, should reduce load capacity and improve user's engineering outside the fault-current protection multiple, particularly system again.Traditional inverted SF
6Gas insulated high voltage current transformer is because its Primary Conductor generally adopts inside and outside nested structure; Once maximum can realize four circles; For accurate limit value coefficient height and the little product of current ratio must increase iron core to realize this performance during design, it is very big that this just causes that product structure does; Not only increase cost, and caused the wasting of resources.
The utility model content
In order to solve the problem that exists in the background technology, the utility model has designed a kind of inverted SF
6Gas insulated high voltage current transformer, purpose is: thus dwindle the product overall dimensions through improving the product number of ampere turns, product structure is rationalized more.
The technical solution of the utility model:
A kind of inverted SF
6Gas insulated high voltage current transformer; Comprise housing, secondary winding assembly, radome, base, secondary outlet box and density controller; It is characterized in that: said instrument transformer also comprises the outdoor insulative cable; The outdoor insulative cable passes from primary shielding pipe and secondary winding assembly center, is wrapped on the housing and through the cable protective case is spacing to fix.Under the running environment that does not change traditional instrument transformer concentric cylinder electric field, improve the product number of ampere turns through regulating the outdoor insulative cable winding number of turn, avoided because of cable is wrapped on the secondary winding assembly, and caused product structure to increase in order to satisfy the insulation spacing.When improving the product dynamic stability, dwindled the current transformer overall dimensions effectively.
The beneficial effect of the utility model:
The design adopts the outdoor insulative construction of cable to substitute traditional aluminum pipe, dwindles the product overall dimensions thereby improve the product number of ampere turns effectively, and product structure is rationalized more.When guaranteeing properties of product, reduce the production cost, improved cost performance of product.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of inverted SF
6Gas insulated high voltage current transformer comprises explosion-protection equipment 1, secondary winding assembly 2, housing 3, primary connection terminal 4, outdoor insulative cable 5, primary shielding pipe 6, cable protective case 7, disk insulator 8, radome 9, high-tension insulating bushing 10, lead-in wire shielded-plate tube 11, base 12, secondary outlet box 13 and density controller 14; Secondary winding assembly 2 is positioned at the synthetic device body of housing 3, disk insulator 8; Outdoor insulative cable 5 passes from the center of primary shielding pipe 6 and secondary winding assembly 2 according to the product needed coiling number of turn, and two ends are connected with P1, P2 side terminal respectively.And it is spacing fixing with housing 2 through cable protective case 7.The design's characteristics are that the outdoor insulative cable is wrapped in outside; Under the running environment that does not change traditional instrument transformer concentric cylinder electric field; Improve the product number of ampere turns through regulating the outdoor insulative cable winding number of turn, take into account and dwindled the current transformer overall dimensions when improving product dynamic and thermal stability performance effectively.
To sum up the utility model accomplishes the end in view.
