Abstract
The utility model relates to a novel CT mounting structure for an IPB center. The mounting structure comprises a bus housing, a CT and a conductor connecting plate arranged in the bus housing, and an adjusting device arranged on the bus housing, wherein the conductor connecting plate penetrates through the CT and is used for two conductors, and the adjusting device is used for adjusting axial position of the CT. The upper portion of the bus housing is equipped with an opening whose size is greater than that of the CT, a flange is arranged in the periphery of the opening, and a cover plate is fixed on the flange via a bolt. When the CT is mounted, the CT can be hoisted by a bridge crane and then placed into the bus housing through the opening in the upper portion of the bus housing, thereby providing convenience for assembly. Then, the adjusting device adjusts the axial position of the CT, thereby adjusting different axial deviations of the CT.
Description
Technical field
The utility model relates to IPB enclosed busbar technical field, is specifically related to the CT mounting structure at IPB center.
Background technology
Existing IPB center C T mounting structure mainly is welded by 1060 aluminiums, generally support reinforcing plate, adjustable bolt anti-loosening locking mechanism, consists of.Because CT is heavier, during installation, often need to utilize row to hang lifting construction, but existing mounting structure does not lift installation.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of convenient novel I PB center C T mounting structure of installing.
The utility model overcomes the technical scheme that its technical problem adopts:
This novel I PB center C T mounting structure, comprise bus shell, be arranged at the interior CT of bus housing, pass CT for the conductor connecting plate of two conductors and be arranged on the bus housing for adjusting the adjusting device of CT axial location, the top of described bus shell is provided with opening, the size of described opening is greater than the overall dimension of CT, described opening surrounding is provided with flange, and a cover plate is secured by bolts on flange.
Above-mentioned adjusting device comprises the some bolts that are plugged in the bus housing, be disposed with spring washer and plain washer between the bolt head of described bolt and bus shell, one nut screws the bottom of being fixed in the bus housing, the bottom of described bolt screws to be fixed in CT, and it is locked by nut spring packing ring and plain washer successively.
In order to improve sealing property, be provided with O type circle between above-mentioned cover plate and bus housing.
In order to prevent the bus housing distortion, the bolt connecting portion of above-mentioned bus housing top is fixed with stiffener.
The beneficial effects of the utility model are: can be by the row CT that slings when CT is installed, and afterwards by putting in the bus housing in the opening above the bus housing, the carrying out of work convenient for assembly.Adjust afterwards the axial location of CT by adjusting device, the malalignment deviation of CT is adjusted.

Embodiment
Below in conjunction with accompanying drawing 1 to 5 pairs of the utility model of accompanying drawing, be described further.
This novel I PB center C T mounting structure, comprise bus shell 1, be arranged at the interior CT 2 of bus housing 1, pass CT 2 for the conductor connecting plate 3 of two conductors and be arranged on bus housing 1 for adjusting the adjusting device of CT axial location, the top of described bus shell 1 is provided with opening, the size of described opening is greater than the overall dimension of CT 2, described opening surrounding is provided with flange 4, one cover plates 5 and is secured by bolts on flange 4.When being installed, CT 2 can, by the row CT 2 that slings, put into afterwards in bus housing 1 the carrying out of work convenient for assembly in the opening by bus housing 1 top.Adjust afterwards the axial location of CT 2 by adjusting device, the malalignment deviation of CT 2 is adjusted.
Adjusting device can for following structure, it comprises the some bolts 8 that are plugged in bus housing 1, be disposed with spring washer 10 and plain washer 11 between the bolt head of described bolt 8 and bus shell 1, one nut 9 screws the bottom of being fixed in bus housing 1, the bottom of described bolt 8 screws to be fixed in CT 2, and it is locked by nut 9 spring washers 10 and plain washer 11 successively.By swivel bolt 8, can make CT 2 move along the axis direction of bolt 8, therefore by some bolts 8, can realize adjusting the axial location of CT 2.Screw two nuts 9 after adjustment and can realize the fixing of bolt 8, and can play relaxation effect by spring washer 10 and plain washer 11.
By be provided with O type circle 6 between cover plate 5 and bus housing 1, can improve the sealing between cover plate 5 and bus housing 1, prevent entering of dust etc., improved useful life.
