Abstract
The utility model discloses a GIS is with shielding structure who takes isolator voltage transformer, including an insulator spindle, two shield rings are installed at the interval on the insulator spindle, pass through fastener difference fixed mounting once conductor and isolator operating mechanism at the axial both ends of insulator spindle. The utility model discloses a GIS is with shielding structure who takes isolator voltage transformer simple structure, operation convenient to use, easily installation can guarantee effectively moreover that the inside insulating properties of product is good, and the electric field is balanced, and the office puts qualifiedly.
Description
Technical field
The utility model relates to voltage transformer, is specifically related to the shielding construction of a kind of GIS band isolator voltage transformer.
Background technology
Along with the development of power system, voltage range improves constantly thereupon, and power system is more and more higher to the requirement of the salient featuress such as the insulativity of High-Voltage Electrical Appliances, operation stability, dielectric recovery property. In recent years, gas-insulated medium, gradually for High-Voltage Electrical Appliances, is especially used widely in fully closed combined electric unit (hereinafter referred to as GIS). From the development of domestic and international power transmission and transforming equipment, air insulating device has become present age High-Voltage Electrical Appliances, the particularly main flow of ultra-high voltage electrical equipment.
Gas isolated electromagnetic potential transformer is as the core product in power system, along with the continuous expansion of domestic and international market, GIS band isolator voltage transformer is more prevalent in the use of electricity power engineering, interiors of products is provided with isolator operating mechanism, complex structure, the requirement of product insulating property and shelf depreciation, apart from short, are therefore required very high by operating mechanism and Primary Conductor.
Practical novel content
For the deficiencies in the prior art, the purpose of this utility model aims to provide the shielding construction that a kind of structure is simple, install easy to operate GIS band isolator voltage transformer.
For achieving the above object, the utility model adopts following technical scheme:
A shielding construction for GIS band isolator voltage transformer, comprises an insulating bar, and on insulating bar, interval is provided with two shield rings, is installed with Primary Conductor and isolator operating mechanism respectively by fastening piece at the axial two ends of insulating bar.
As the utility model GIS a kind of improvement of the shielding construction of band isolator voltage transformer, described shield ring smooth surface, in circular shape.
Improving as the utility model GIS another kind of the shielding construction of band isolator voltage transformer, the distance between described Primary Conductor and isolator operating mechanism is 60-200mm.
As the utility model GIS another improvement of the shielding construction of band isolator voltage transformer, described fastening piece is bolt.
The beneficial effects of the utility model are:
The shielding construction structure of GIS band isolator voltage transformer of the present utility model is simple, easy for operation, it is easy to install, by being provided with shield ring on insulating bar, effectively the sharp arris angle of Primary Conductor, on-off mechanism, fastening piece can be shielded, shield ring smooth surface, circular-arc-shaped design, thus shield ring surface electric field distribution is even, and electric discharge phenomena not easily occur.
Accompanying drawing explanation
Fig. 1 is the structural representation of the shielding construction of the utility model GIS band isolator voltage transformer;
1, insulating bar; 2, shield ring; 3, fastening piece; 4, Primary Conductor; 5, isolator operating mechanism.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, for the structural representation of shielding construction of the GIS band isolator voltage transformer of the better embodiment of the utility model, comprise an insulating bar 1, on insulating bar 1, interval is provided with two shield rings 2, it is installed with Primary Conductor 4 and isolator operating mechanism 5 respectively by fastening piece 3 at the axial two ends of insulating bar 1, wherein Primary Conductor 4 is high pressure side, and isolator operating mechanism 5 is ground terminal; In the present embodiment, two shield rings 2 are installed on insulating bar 1 two ends, and shield ring 2 is by alloy material impact briquetting, have that weight is light, intensity height, the features such as machinery and excellent electrical properties.
When this product reality uses, whole product seals completely, inside is insulation gas filled, there is provided effective to the reliability run, when isolator operating mechanism 5 action, shield ring 2 also and then moves up and down, it is all the axial two ends being fixedly installed in insulating bar 1 due to Primary Conductor 4 and isolator operating mechanism 5, make the structure of whole product very simple like this, install easy to operate, simultaneously by being provided with shield ring on insulating bar, it is thus possible to effectively to Primary Conductor, on-off mechanism, the sharp arris angle of fastening piece shields, to prevent there is the phenomenon of electric discharge in product, there is good shield effectiveness.
In addition, in order to the shield effectiveness of this product made is better, above-mentioned shield ring smooth surface, in circular shape.
Wherein, if the distance between operating mechanism and Primary Conductor is too short, can the requirement of product insulating property and shelf depreciation be required very high, be unfavorable for the production quantized; Otherwise, if the distance between operating mechanism and Primary Conductor is excessively long, then the profile of whole product can be caused excessive, add production cost. Research repeatedly through contriver finds, when the distance between above-mentioned operating mechanism and Primary Conductor is 60-200mm, under the prerequisite meeting product insulating property, and can realize product miniaturization Design, reduce production cost.
Meanwhile, in order to facilitate Primary Conductor 4 and the installation and maintenance of isolator operating mechanism 5, above-mentioned fastening piece 3 is bolt, certainly, fastening piece 3 is also not limited only to the bolt described in the present embodiment, if other can realize fixed installation parts also can, such as screw etc.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and these all changes and deformation all should belong within the protection domain of the utility model claim.
