Description

Technical Field

[0001] The utility model belongs to the technical field of medium and high voltage switch cabinets, and in particular relates to a main busbar fixing structure. Background Art

[0002] Most current gas tanks are split-box type, requiring multiple tanks to be spliced ​​together, which increases losses. The fixing method and shape of the main busbar also make the electric field less than ideal, resulting in some discharge. Utility Model Content

[0003] In order to solve the above problems, the present invention adopts the following technical solutions:

[0004] A main busbar fixing structure, comprising:

[0005] A plurality of main busbars, wherein the plurality of main busbars are arranged side by side;

[0006] a plurality of insulating plates, the plurality of insulating plates being arranged perpendicular to the plurality of main busbars and spaced apart on the upper side of the main busbars;

[0007] The insulating plate and the main busbar are fixed by a connector, and a heightening gasket is provided between the insulating plate and the main busbar. The outer surface of the connector at both ends away from the insulating plate is provided with a first shielding member.

[0008] Furthermore, there are three main busbars and three insulating plates.

[0009] Furthermore, the main busbar is provided with a plurality of bending structures at intervals along the length direction.

[0010] Furthermore, a plurality of second shielding members are arranged at intervals on a side of the insulating plate away from the first shielding member.

[0011] Beneficial effects of the utility model:

[0012] The utility model is a three-box integrated main busbar. The single-phase main busbar is a whole. Compared with the discontinuous main busbar of the divided box type, this has better conductivity and reduces loss.

[0013] The utility model has three insulating plates and three shielding fixed main busbars. The special structure of the main busbar makes the entire electric field better, thus reducing the possibility of discharge and making the weather safer.

[0014] The utility model uses a heightened gasket between the main busbar and the insulating plate to isolate the insulating plate and the main busbar, which improves the pressure resistance and ensures that the entire structure can operate more safely under the specified voltage.

[0015] The insulating plate and the main busbar of the utility model form a frame structure as a whole, which also increases the structural strength of the gas box and ensures safety. BRIEF DESCRIPTION OF THE DRAWINGS
