Description
Technical field
The utility model relates to a kind of pick-up unit, particularly insulation test device.
Background technology
GIS gas insulation switch cabinet in recent years at home development rapidly, be all contained in its supporting components and parts and be filled with in the metal enclosed cabinet of sulfur hexafluoride gas, voltage transformer (VT) is one of components and parts wherein.
The voltage transformer (VT) supporting due to GIS gas insulation switch cabinet is placed in sulfur hexafluoride gas, thus it is different with the aerial external insulation of installation, so cannot Insulation Test be done in atmosphere, current most of producer imitates to do experiment at sulfur hexafluoride gas insulation switch cabinet, not only test unit is complicated, and labour intensity is large, inefficiency.
Summary of the invention
The purpose of this utility model be just to provide a kind of simple to operate, easy for installation while the low GIS gas insulation switch cabinet also can increased work efficiency of labour intensity supporting voltage transformer (VT) insulation test device.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
Insulation test device, comprise the sulfur hexafluoride gas in insulating cylinder and insulating cylinder, it is characterized in that: below insulating cylinder, metal flange is set, metal flange contacts with on transformer casing, the center of insulating cylinder is provided with conducting rod, insulating cylinder upper center arranges porose, and conducting rod passing hole enters the inner chamber of insulating cylinder, and the top of conducting rod is provided with charging valve; Inside described metal flange, cover has O-ring seal, prevents sulfur hexafluoride gas from leaking; Be provided with pore inside described conducting rod, one end of pore is connected on charging valve.
Described sulfur hexafluoride gas is entered in insulating cylinder through air passing hole by the charging valve opened.
Below described conducting rod, the position that of mutual inductor time terminal is connected is provided with screw thread.
The similar capital L of shape of described pore.
The shape entirety of described pore is curve.
The labour intensity low feature also can the increased work efficiency while that insulation test device described in the utility model having simple to operate, easy for installation.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Charging valve, 2, conducting rod, 3, insulating cylinder, 4, sulfur hexafluoride gas, 5, mutual inductor leading-out terminal, 6 metal flanges, 7, O-ring seal, 8, transformer casing, 9, pore.
Embodiment
