Abstract
The utility model relates to an iron core clamp grounding device for a transformer. A wiring board is arranged outside the tank cover of an oil tank, and a grounding wire is leaded to the upper end plane of the tank cover through an iron core clamp and is crimped on the wiring board; a rain cover is hermetically arranged at the upper part of the wiring board, the wiring board is in an annular structure, and the grounding wire is crimped on the grounding board through a wiring screw by a connecting member. According to the iron core clamp grounding device, a screw and wiring terminal type connecting structure is adopted in an iron core clamp grounding structure, the grounding wire is convenient to connect, simple to operate, and reliable and intuitive to connect, so that the iron core clamp grounding device can be obtained by only purchasing the wiring board and processing a rainproof cover.
Description
Technical field
The utility model relates to a kind of Transformer Manufacturing Technology, specifically a kind of iron core folder earthing device for transformer.
Background technology
In transformer ' s type product is manufactured, for avoiding structural member electric potential floating to cause electric discharge, iron core and folder must effective groundings.As shown in Figure 1, in design of transformer, conventionally iron core and folder are drawn to case lid 2 by earth cable 3 through grounding sleeve 1, at oil tank of transformer external ground.While adopting this ground structure to arrange, to consider the installing space of two grounding sleeves 1, particularly on little fuel tank or case lid 2 when the more insufficient space of structural member, it is particularly outstanding that problem seems, can make the layout of grounding sleeve 1 loaded down with trivial details and difficult, and can increase grounding sleeve 1 cost, this is also the problem that can not ignore.
Utility model content
Exist and arrange loaded down with trivial details, the weak point such as large that takes up room for iron core folder grounding sleeve in prior art, the technical problems to be solved in the utility model is to provide a kind of simple compact iron core folder earthing device for transformer of iron core folder ground structure that makes.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of iron core folder earthing device for transformer of the utility model, is provided with terminal block in the case lid outside of fuel tank, and ground lead leads to case lid upper surface by iron core folder, is crimped on terminal block; Top seal at terminal block is provided with rain cover.
Described terminal block is loop configuration, and ground lead is crimped on terminal block through wiring screw rod by brace.
After ground lead is crimped on terminal block, then connect earth cable, this earth cable is drawn on the ground structure that is connected to cabinet exterior bottom through rain cover.
The utlity model has following beneficial effect and advantage:
1. in the utility model iron core folder ground structure, adopt screw rod, terminals minor syndeton, ground lead is easy to connect, simple to operate, connects reliable directly perceived;
2. adopt the utility model iron core folder ground structure can make on area occupied and height, to take up room and significantly dwindle on case lid, avoid because interfering and cause that grounding sleeve arranges loaded down with trivial details problem with other structural members on insufficient space on case lid or height, and simple compact profile is attractive in appearance;
3. adopt the utility model iron core folder ground structure can make the manufacturing cost of product reduce, use every product of traditional iron core folder ground structure at least to need to purchase two grounding sleeves, and in new structure, only need terminal block of buying and a rain cover of processing.
Brief description of the drawings
Fig. 1 is traditional iron core folder ground structure schematic diagram;
Fig. 2 is the rain cover inner ground structure schematic diagram of the utility model iron core folder at fuel tank;
Fig. 3 is the utility model iron core folder brace schematic diagram in the inner ground structure of rain cover of fuel tank;
Fig. 4 is that the utility model iron core folder earth connection is drawn fuel tank external ground structural representation;
Fig. 5 is that the utility model iron core folder earth connection is drawn in fuel tank external ground structure and drawn ground line configuration schematic diagram.
Wherein, 1 is grounding sleeve, and 2 is case lid, and 3 is earth cable, and 4 is ground lead, and 6 is brace, and 7 is wiring hole, and 8 is ground connection mark, and 9 is rain cover, and 10 is terminal block, and 11 is wiring screw rod.
Embodiment
Below in conjunction with Figure of description, the present invention is further elaborated.
The utility model provides two kinds of earthing modes, has banned sleeve pipe ground structure of the prior art.
As shown in Fig. 2～3, the first earthing mode is: case lid 2 outsides at fuel tank are provided with terminal block 10, and ground lead 4 leads to case lid 2 upper surfaces by iron core folder, are crimped on terminal block 10, are provided with rain cover 9 in the top seal of terminal block 10.
This kind of earthing mode can be saved the manufacturing cost of product.In structure, every product need be purchased at least two grounding sleeves 1 in the past, and in this kind of structure, only needed terminal block of buying 10 and a rain cover 9 of processing.The manufacturing cost of product reduces, the especially manufacture to many volume production product, and the cost of reduction is considerable.
As shown in Figures 4 and 5, in the second earthing mode and embodiment 1, difference is: after ground lead 4 is crimped on terminal block 10, then connect earth cable 3, this earth cable 3 is drawn on the ground structure that is connected to cabinet exterior bottom through the wiring hole 7 of rain cover 9.
It is loaded down with trivial details that the utility model adopts above two kinds of structures to solve grounding sleeve layout, the larger problem that takes up room, makes iron core folder ground structure simply compact, simple to operate, good looking appearance, all has positive meaning to saving cost of goods manufactured, raising product competitiveness aspect.
