Abstract
The utility model relates to the technical field of electric equipment, in particular to a 110-kilovolt high-voltage sulfur hexafluoride gas insulation current transformer, which resolves problems that the prior art is large in occupied space and poor in use effect. The technical scheme includes that the 110-kilovolt high-voltage sulfur hexafluoride gas insulation current transformer comprises a body structure, the body structure comprises a metal casing, a shielding part, an insulation supporting part and a primary conductor, the shielding part and the insulation supporting part are disposed in the metal casing, the primary conductor penetratingly provided with the shielding part and erected at two ends of the metal casing, and the shielding part is fixedly connected with the metal casing through the insulation supporting part. The 110-kilovolt high-voltage sulfur hexafluoride gas insulation current transformer is characterized in that the insulation supporting part is disposed longitudinally, and the upper end of the insulation supporting part is fixedly connected with the lower portion of the shielding part while the lower end of the insulation supporting part is fixedly connected with the inner side of the metal casing. Compared with the prior art, the 110-kilovolt high-voltage sulfur hexafluoride gas insulation current transformer has the advantages of fine effect and simple process.
Description
Technical field
The utility model relates to electrical equipment technical field, is specifically related to a kind of 110 kilovolts of high pressure sulfur hexafluoride gas insulated high voltage current transformer.
Background technology
At present, 110 kilovolts of high pressure sulfur hexafluoride gas insulated high voltage current transformer of power system operation, its general structure comprises: the body, sleeve pipe and base, the said body generally comprises: metal shell, shielding part, insulated support and Primary Conductor, shielding part and insulated support are arranged in the metal shell, Primary Conductor is passed shielding part and is set up in the metal shell two ends, one end of shielding part is fixedlyed connected with metal shell by insulated support, and promptly insulated support adopts the setting of " cantilever type " structure.Its main drawback is: the first, and insulated support takies certain space, causes secondary winding limited, must solve by increasing parts length such as shielding part, metal shell.The second, because the insulated support torsion of this structure is bigger, when transportation, may there be certain potential safety hazard, the product reliability of operation is affected.The 3rd, owing to article one reason, cause Primary Conductor longer, the anti-dynamic and thermal stability ability of product is relatively poor: heat-stable current has only 31.5kA/3s in short-term; Dynamic current can only reach 80kA.
Summary of the invention
The purpose of this utility model is that a kind of 110 kilovolts of high pressure sulfur hexafluoride gas insulated high voltage current transformer will be provided, with taking up room greatly and the problem of result of use difference that the solution prior art exists.
In order to solve the problem that prior art exists, the technical solution adopted in the utility model is:
A kind of 110 kilovolts of high pressure sulfur hexafluoride gas insulated high voltage current transformer, comprise body structure, described body structure comprises metal shell 1, shielding part 2, insulated support 4 and Primary Conductor 3, shielding part 2 and insulated support 4 are arranged in the metal shell 1, Primary Conductor 3 wears shielding part 2 and is set up in metal shell 1 two ends, shielding part 2 is fixedlyed connected with metal shell 1 by insulated support 4, it is characterized in that: described insulated support 4 vertically is provided with, fixedlying connected with the bottom of shielding part 2 in its upper end, fixedlys connected with the inboard of metal shell 1 in the lower end.
The bottom of above-mentioned metal shell 1 is provided with insulated support standing groove 5, and the lower end of insulated support 4 is arranged in the insulated support standing groove 5.Structure is more firm.
Compared with prior art, advantage of the present utility model is as follows:
Effective, technology is simple: improved body structure, insulated support is arranged on shielding part below, parts such as shielding part, metal shell obviously shorten, and have also reduced the influence of torsion to insulated support simultaneously, the potential safety hazard when having eliminated transportation; Technology is simple, has also reduced cost, and improve the product operational reliability, and the anti-dynamic and thermal stability ability of product improves a lot: heat-stable current can reach 50kA/3s in short-term; Dynamic current reaches 125kA, and the product technology performance reaches advanced international level.
