Description
Technical field
This utility model relates to converter power transformer technical field, is specifically related to a kind of converter power transformer iron core grounding structure.
Background technology
Large-sized converter transformer is when hanging net operation or charging test, iron core and folder are in non-uniform electric field, charged winding can make to produce certain floating potential between iron core and the earth by Capacitance Coupled effect, the local of potential difference can be had continuous discharge phenomenon is produced to fuel tank etc., therefore it is required that iron core and the necessary effective grounding of folder, iron core is made to be in zero potential.And when iron core has and above ground connection at 2, core interior can produce circulation between each junction point, causes iron core hot-spot fault.So iron core and folder must maintain and only have some reliable grounds.
The tradition iron core of iron core ground structure and the lead-out wire of folder are reliably connected with the earthing rod within cover plate, but when shortcoming measures core current exactly, need remove cover plate and need external grounding sleeve, be unfavorable for the real time on-line monitoring to core current.
When checking iron core and clamp insulation performance thereof, the securing member on flange need to be backed out, then iron core and folder are carried out insulating properties detection.Lug plate in conventional fastener is enclosed type manhole, and this structure in operation, all will screw out fastening bolt from fixture, could meet the needs exiting or accessing lug plate.And the most not retraining between each parts of this structure, when fastening or open lug plate, securing member is easy to scatter and come off, and makes troubles operation.
Utility model content
The purpose of this utility model is to overcome in conventional art checking iron core and easily cause assembly during folder and come off, the technical problem made troubles to operation, it is provided that the converter power transformer iron core grounding structure of a kind of convenient operation.
This utility model solves its technical problem and be the technical scheme is that a kind of converter power transformer iron core grounding structure, including tank wall, securing member and sealing ring, the first flange it is sequentially provided with on tank wall, second flange, by securing member and sealing ring by the first flange, second flange is close-coupled on tank wall, second flange also sets up and has a liter dais, rise dais top and be provided with grounding sleeve, described grounding sleeve top is connected with fuel tank earth terminal, bottom connects connection sheet, also include iron core grounding wire and folder earth lead, described iron core grounding wire and folder earth lead by be connected after sheet is connected the most external, concrete iron core grounding wire is connected outside outlet box with the grounding sleeve risen on dais by connecting sheet with folder earth lead, it is connected to fuel tank earth terminal.
Said two grounding sleeve is fixed on liter dais, one end is connected with iron core grounding wire and folder earth lead respectively by connecting sheet, and the other end is connected with fuel tank earth terminal, can be directly connected to monitor when needs are measured, need not take apart cover plate, conveniently core current is monitored in real time.
Securing member includes bolt, the lug plate that can be connected with iron core grounding wire, folder earth lead respectively, being provided with spring washer and packing ring in the middle of bolt and lug plate, bolt root is provided with semi-circular threaded that is that be half opening in the middle of escape, lug plate and that mate with bolt.This structure in operation, as long as securing member bolt is screwed out several screw thread mouths, just can reach to exit or access the purpose of lug plate.After connecting sheet screw-in Gewindefreistiche, due to lug plate threaded function, making packing ring, spring washer, bolt and lug plate become an entirety, all parts cannot come off from lead-in wire.
Between described first flange and the second flange, it is additionally provided with epoxy plate, securing member and sealing ring the first flange, epoxy plate and the second flange are close-coupled on tank wall.By epoxy plate, strengthen insulation against ground intensity.
Described first flange, epoxy plate and the second flange are respectively set to disc.
This utility model, compared with tradition earthing mode, has simple in construction, it is easy to operation, the advantage that feasibility is strong, can monitor the real-time of multipoint earth faults, and this ground structure is easy to make, is hardly damaged, low cost while realizing iron core reliable ground.
