Abstract
A comb-shape copper holding device for mine flame-proof type transformer is provided, which comprises two same shape cover boards made of insulative materials, a comb shape nick used for clamping a copper holding is arranged on the cover board, the number of the comb-shape nick correspond with the number of the connected copper holding, the copper holding is clamped between the comb shape nick circled by two cover boards, a fixing hole is arranged on the cover board, the cover board is connected to the shell body of the transformer by the fixing hole. The current technology adopts extracting the copper holding flatly, the occupied volume is relatively larger, and then the occupied volume of the transformer is relatively larger. Under the requirements of small volume underground installation, which is obviously inconvenient to transport and install. The holding device in the utility model extracts copper holding vertically, this structure reduces the installation volume of the transformer, thus making the underground installation of the transformer more convenient. Besides, the vertical type installation has lower cost than the horizontal installation, and the mechanical force is smaller too.
Description
Technical field
The utility model relates to a kind of copper bar clamping device, relates in particular to a kind of flame-proof mine transformer pectination copper bar clamping device.
Background technology
In the past, copper bar was that level is drawn in the flame-proof mine transformer, and fixture is to adopt the wire clamp of band groove.In general dry-type transformer, copper bar also has upright drawing, and adopts the insulator to fix.Why not employing level is drawn or is adopted insulator to be fixed, mainly be to be placed in the flame proof housing because flame proof becomes his device body, the employing level is drawn or the fixing installation dimension of whole device body that must cause of insulator becomes big, also must cause the change of housing big, because flameproof mining transformer is used under the coal mine, a big more difficulty of installing and transporting that just increased of volume!
Summary of the invention
The utility model provides a kind of and is easy to install, manufacturing, good fixing effect, reduce the Dressing Copper Clamping Device For Mine Explosion-proof Transformer of volume of transformer.
The utility model adopts following technical scheme:
A kind of Dressing Copper Clamping Device For Mine Explosion-proof Transformer, comprise the identical shaped cover plate that has that two insulating material make, cover plate is provided with the pectination breach that is used for the clamping copper bar, the number of pectination breach is suitable with the copper bar number that needs to be connected, copper bar is held in the pectination breach that two cover plates surround, cover plate is provided with fixing hole, and cover plate is connected on the housing of transformer by fixing hole.
The utility model obtains following technique effect:
1. prior art is drawn the copper bar level, shared volume is bigger, thereby the shared volume of transformer is bigger, wanting the little underground installation of cube, obviously transport, install inconvenience, the utility model clamping device is vertically drawn copper bar, and this structure makes the installation volume of transformer reduce, thereby makes transformer more convenient in underground installation.In addition, vertical installation is littler than level installation eddy current loss, and mechanical force is also smaller.
2. with respect to existing complex-shaped, larger-size clamping device, of the present utility model simple in structure, saved the manufacturing raw material, thereby cost is reduced significantly.
3. original groove type fixture needs to produce the part of multiple shape, and the utility model pectination clamping device adopts two identical shaped cover plates altogether, just can be used as clamping device and use, only need produce a kind of part of shape, thus easily manufactured, cost is low, and it is also convenient to install.
For the overall dimensions of controller body, the copper bar of low-voltage coil is drawn to adopt standing and is drawn, and adopts the pectination wire clamp to be fixed in order to keep the distance between copper bar.

Embodiment
Embodiment
A kind of flame-proof mine transformer pectination copper bar clamping device, what comprise that two insulating material make has an identical shaped cover plate 1, cover plate is provided with the pectination breach 2 that is used for the clamping copper bar, the number of pectination breach 2 is suitable with the copper bar number that needs to be connected, copper bar 3 is held in the pectination breach 2 that two cover plates surround, cover plate is provided with fixing hole 4, and cover plate is connected on the housing 5 of transformer by fixing hole 4.
The length of pectination wire clamp is decided by the distance of the copper bar of drawing apart from folder, and the distance of comb is decided by the thickness of copper bar, and comb thickness is decided by electric pressure; The pectination wire clamp adopts insulating sheet material to mill out with milling machine as requested.
In the related flame-proof mine transformer of the utility model kind, 2500KVA, 3150KVA, the drawing of 4000KVA low-voltage copper bar adopted perpendicular (standing) and drawn,
