Description
Technical field
The utility model relates to a kind of oil tank of transformer magnetic screen external ground structure, belongs to oil tank of transformer magnetic screen grounding apparatus technical field.
Background technology
Existing oil tank of transformer magnetic screen ground structure is all to adopt magnetic shield panel to be connected with inner wall of oil tank, the mode of ground connection by fuel tank ground connection, this kind of earthing mode just cannot be learnt whether reliable ground of magnetic screen after transformer installation, if magnetic screen and fuel tank are failed reliable electric and are connected, user cannot learn this situation, and continuation operating transformer will cause producing a large amount of losses in tank wall even to produce local overheating, have a strong impact on the safe and reliable operation of transformer.
Utility model content
The utility model object is to provide a kind of oil tank of transformer magnetic screen external ground structure, can guarantee magnetic screen reliable ground, solves the problem existing in background technology.
The technical solution of the utility model is:
A kind of oil tank of transformer magnetic screen external ground structure, comprise magnetic shield panel, lug plate, copper bar, bent plate, insulating board, paper bag cable, outer sleeve and ground plate, several magnetic shield panels are arranged side by side, between magnetic shield panel top and copper bar, be connected by lug plate, copper bar outside is provided with insulating board, and be fixed on transformer oil tank wall by bent plate, paper bag cable one end connects copper bar end, the other end is through outer sleeve and by ground plate ground connection.
Between described magnetic shield panel, be provided with fixed head, between copper bar and transformer oil tank wall, be also provided with cushion block.
Described magnetic shield panel gap below is provided with copper bar.
Described lug plate is soft copper sheet.
The beneficial effects of the utility model are: simple in structure, can guarantee magnetic screen reliable ground, and guarantee the reliability service of transformer.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the fixing schematic diagram of the utility model copper bar;
The oil tank of transformer magnet shielding structure schematic diagram that Fig. 3 is interrupted in the middle of being;
In figure: magnetic shield panel 1, fixed head 2, lug plate 3, copper bar 4, bent plate 5, insulating board 6, paper bag cable 7, outer sleeve 8, ground plate 9, transformer oil tank wall 10, cushion block 11.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of oil tank of transformer magnetic screen external ground structure, comprise magnetic shield panel 1, lug plate 3, copper bar 4, bent plate 5, insulating board 6, paper bag cable 7, outer sleeve 8 and ground plate 9, lug plate 3 is soft copper sheet, all magnetic shield panels 1 are linked together with a copper bar 4, between magnetic shield panel 1 top and copper bar 4, adopt soft copper sheet to be connected, soft copper sheet has played the effect being flexible coupling, at copper bar 4 both ends and central position the fixing copper bar of bent plate 5 is set, described bent plate 5 is made by 2mm steel plate, one end is welded on transformer oil tank wall 10, copper bar 4 is placed between bent plate and transformer oil tank wall, and then bent plate is manually bent, fasten copper bar, with reference to accompanying drawing 2, between transformer oil tank wall 10 and copper bar 4, place 15mm heavy insulation cushion block 11, guarantee the insulation distance of copper bar to transformer oil tank wall, with insulating board, copper bar is wrapped up to every limit 2mm at fixed head place thick, guarantee that copper bar is to the insulation property between fixed head, paper bag cable 7 causes outer sleeve 8 from copper bar 4 ends along transformer oil tank wall inwall, the use of paper bag cable is changeable flexibly by the position of outer sleeve, can be positioned over any position of fuel tank end face and end face, finally by outer sleeve 8 through ground plate 9 ground connection.
With reference to accompanying drawing 3, in phase modulation sell of one's property product, because becoming fuel tank and encourage change fuel tank, string has perforate by Adam's apple connection transformer fuel tank tank wall, so it is two sections that magnetic shield panel 1 is often interrupted, for this kind of situation, magnetic shield panel and the top that a copper bar interrupts bottom is set in the lower end of magnetic shield panel 1 again and connects together.
Claims (4)
1. an oil tank of transformer magnetic screen external ground structure, it is characterized in that comprising magnetic shield panel (1), lug plate (3), copper bar (4), bent plate (5), insulating board (6), paper bag cable (7), outer sleeve (8) and ground plate (9), several magnetic shield panels (1) are arranged side by side, between magnetic shield panel (1) top and copper bar (4), be connected by lug plate (3), copper bar (4) outside is provided with insulating board (6), and be fixed on transformer oil tank wall (10) by bent plate (5), paper bag cable (7) one end connects copper bar (4) end, the other end is through outer sleeve (8) and by ground plate (9) ground connection.
