Embodiment
Below in conjunction with accompanying drawing, the utility model and embodiment thereof are described in further detail:
See Fig. 1 to Fig. 3, the utility model comprises for canular outer insulator 1, copper cash 2, measuring coil and iron core 3, creep distance structure and mounting platform 5 is provided with outside described outer insulator 1, it is characterized in that: also comprise interior insulator 4, described outer insulator 1 wraps up interior insulator 4 outer wall, described measuring coil and iron core 3 to be located in outer insulator 1 and contactless type around interior insulator 4, described copper cash 2 is separated by interior insulator 4 with outer insulator 1.
Described outer insulator 1 is epoxy resin glue.
Described interior insulator 4 is polytetrafluoroethylene film and silicon rubber.
Described mounting platform 5 maximum radial cross section is 200mm × 120mm.
The utility model comprises for canular outer insulator 1, copper cash 2, measuring coil and iron core 3, creep distance structure and mounting platform 5 is provided with outside described outer insulator 1, it is characterized in that: also comprise interior insulator 4, described outer insulator 1 wraps up interior insulator 4 outer wall, described measuring coil and iron core 3 to be located in outer insulator 1 and contactless type around interior insulator 4, described copper cash 2 is separated by interior insulator 4 with outer insulator 1, the thermal expansion effects that interior insulator 4 realizes between copper cash 2 and outer insulator 1 absorbs, ensure good insulation effect and the electromagnetism perceptual effect of measuring coil and iron core 3 pairs of copper cash 2 simultaneously, reduce the impact of the foreign impacts voltage that margin of error when measuring coil and iron core 3 realize data acquisition and copper cash 2 bring, integral component version under the utility model patent condition is the space structure and the high-strength insulating performance requirement that effectively utilize insulating sleeve, conventional current instrument transformer is embedded in sleeve pipe itself and goes, although conventional current instrument transformer also has the telescopic of correspondence, but they all do not possess the due basic electrical performance demands of insulating sleeve, integrated design under new construction, not only ensure the through-flow and current sample function of corresponding conductor current, but also the guarantee achieved on the basic physical space structure of small occupied space and electrical insulation properties, thus make it be more suitable for the supporting application of the Novel intelligent switch cabinet in Miniaturization Design.
