A kind of main transformer low-pressure side bus bridge earthing clamp, including bus bridge folder, grounding hook, insulating barrier and insulation windows,
Wherein, the bus bridge folder is double-layer structure, and side links together, another side opening, forms the clip-like being connect with bus bridge,
Connection hook includes vertical plate and inclined plate, and the vertical plate is fixed on the connecting side of bus bridge folder, the inclined plate with vertically
The bottom end of plate connects, and is in an oblique angle with vertical plate；
The open side of the bus bridge folder is provided with insulating barrier, passes through insulation windows between the insulating barrier and vertical plate
Connection.
The bus bridge folder is metal material.
The metal material is preferably copper.
The grounding hook is metal material, preferably copper.
The insulation windows be upwards can open type insulation windows, be fixed between grounding hook and insulating barrier, can to push away upwards
Open type designs, and is boundary from center, and the window page that both sides are pushed open upwards makes grounding hook push up windowing page, hangs on grounding hook
On, it is usually closed state, short trouble is caused between preventing foreign matter from bridging two-phase.
The double-layer structure of the bus bridge folder, upper layer and lower layer's equivalent width, the upper layer length are less than the length of lower layer.
The vertical plate upper end of the grounding hook is fixed together with bus bridge folder, and the vertical plate surface is covered with insulation
Sheath, lower end are connect by transition of insulating with insulation windows.
The inclined plate is in 20-40 ° of angle with vertical plate.
The insulating barrier is that front and back right three side sealing closes structure, is made of high-strength insulating material, with bus bridge folder, ground connection
Hook, insulation windows collectively form more closed space.
Beneficial effects of the present invention are：Of simple structure and low cost, installation is easy, in main transformer low-pressure side bus bridge three-phase
Each installation one, you can the suspension that low-pressure side is grounded when main transformer being facilitated to overhaul, and usually since its insulation and obturation designs, and protect
It has demonstrate,proved it and short-circuit fault risk is not present, to ensureing that grid maintenance safety and reliable power supply are of great significance.
Description of the drawings
Fig. 1 is the structure of the main view of the present invention.
Fig. 2 is present invention right side schematic cross-sectional view.
Wherein：1, bus bridge presss from both sides；2, grounding hook；3, side insulation partition board；It 4, upwards can open type insulation windows.
Specific implementation mode：
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, main transformer low-pressure side bus bridge earthing clamp, by bus bridge folder 1, grounding hook 2, side insulation partition board
3 and upwards can open type insulation windows 4 constitute, bus bridge folder 1 and grounding hook 2 be all made of copper, bus bridge folder 1 left end and ground connection
It is welded and fixed and is integrated on the upside of the side vertical end of hook 2, chamfered portion and the side vertical part angle of grounding hook 2 are 30
Degree.Side insulation partition board 3 by insulate transition be fixed on bus bridge folder 1 lower layer, upwards can open type insulation windows 4 by insulated
Cross the lower end for being fixed on 2 side vertical end lower part of grounding hook and side insulation partition board 3.
As shown in Fig. 2, bus bridge folder 1 is made of upper layer and lower layer, second layer length is 100mm, first layer 80mm, convenience
Bus bridge insulation winding, upper layer and lower layer is copper, and wide 50mm, thickness is 8mm.Upper layer and lower layer spacing is 15mm, compares main transformer
