TECHNICAL FIELD

[0002] A casting busbar is a kind of busbar product in which a conductor is completely cast and enclosed by high-performance insulating materials, and is widely used in power systems, especially in occasions with high requirements for power transmission efficiency and safety. In a power transmission and distribution system, the casting busbar, as a key component of power transmission, undertakes the important task of efficiently and safely transmitting electric energy from a generator or a transformer to various power utilization devices. The design of the casting busbar not only requires excellent conductive and insulating properties, but also needs to consider its structural strength, stability and long-term operation reliability, among which, the design of the supporting structure is crucial for improving the overall performance of the casting busbar.

[0003] In the prior art, the supporting mode of the busbar is generally to directly lock the hoisting point on the ceiling by a screw rod or to lock the hoisting point position on the wall surface by a steel structure, however, whether the hoisting point is locked by the screw rod or the steel structure, the busbar is completely fixed in place, and cannot be flexibly adjusted according to the relevant requirements, and in the installation process, a slight error needs to adjust the position of the supporting structure, and the installation convenience is poor.

[0009] Further, the spring is located between the extension frame and the cross support frame, and the two ends of the spring abut against the bottom surface of the extension frame and the upper surface of the cross support frame, respectively.

[0010] By the above scheme, by setting the spring, the two fixed frames can be elastically supported, so that when vibration or earthquake and other unexpected situations occur, the spring can play a good buffering effect.

[0011] Further, the outer part of the two fixed frames is provided with a mounting plate, and the mounting plate is fixedly connected to the wall body by a bolt.

[0012] By the above scheme, the mounting plate can be stably fixed on the wall body by the bolt, thereby improving the overall support stability.

[0013] Further, a guide groove is formed in the outer surface of the mounting plate, and two symmetrical sliding grooves are formed in the inner wall of the guide groove.

[0014] By the above scheme, by setting the sliding groove, the T-shaped slider can be guided, thereby ensuring the directional movement of the T-shaped slider.

[0015] Further, the outer surface of the two cross support frames is fixedly connected with a T-shaped slider, and the outer surface of the T-shaped slider is slidingly connected to the inner wall of the guide groove.

[0016] By the above scheme, by setting the T-shaped slider, the position of the two cross support frames can be quickly adjusted under the sliding of the T-shaped slider, thereby improving the installation efficiency.

[0017] Further, the inner wall of each of the two cross support frames is inserted with two fastening bolts, the through holes in the inner wall of each of the two cross support frames are adapted to the external dimensions of the fastening bolts, and the outer surfaces of the fastening bolts are slidingly connected to the inner wall of the sliding groove.

[0018] Through the above scheme, the fastening bolts and the T-shaped sliding block are stably connected through the sliding groove, and the subsequent fastening bolts can limit and fix the cross support frame.

[0019] Further, the outer surfaces of the two fastening bolts are threadedly connected to the inner wall of the T-shaped sliding block.

[0020] Through the above scheme, the inner wall of the mounting plate is abutted by the fastening bolts after the fastening bolts are turned to the inside of the T-shaped sliding block when the position adjustment of the cross support frame is completed, the position of the cross support frame is limited and fixed, and the stability of the cross support frame is improved.

[0021] Compared with the prior art, the technical scheme of the present application has the following beneficial effects:

[0022] The hoop type elastic support structure for the cast busbar adjusts the tightness of the spring and the distance between the fixed frame and the cross support frame by rotating the nut when there is a small height difference in the actual installation process of the busbar body, so that the position of the entire support does not need to be adjusted again, the repeated installation workload is reduced, and the spring can also well play a buffering and shock avoidance effect when there is a certain vibration or earthquake or other unexpected situation.
