Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage busbar PT compartments, in particular to an insulation auxiliary device for a high-voltage busbar PT compartment. Background Art

[0002] The busbar PT interval is a common concept in power systems, which refers to the distance between the busbar and the PT. In power systems, PT plays an important role in voltage measurement, protection and control, while the busbar is the main transmission channel of the power system. Therefore, the setting of the busbar PT interval is of great significance to the safe and stable operation of the power system.

[0003] In order to maintain the stable output of electricity and the normal operation of power equipment, it is necessary to regularly inspect and maintain the busbar PT compartment. In order to ensure the normal operation of the equipment and protect the personal safety of electricians, an insulating baffle is required when inspecting the busbar PT compartment. The existing method is to install the insulating baffle directly inside the busbar PT compartment. There is no good stable installation method, or the electrician manually supports it by himself, but this will bring inconvenience to the electrician's operation and increase the tediousness of the electrician's labor. Long-term support will cause paralysis of the electrician's arm, so it is necessary to improve the existing device to meet actual needs. Utility Model Content

[0008] Preferably, four groups of overlapping plates are relatively arranged, and a group of connecting plates are fixedly installed on the sides.

[0009] Through the above technical solution, a triangular support device is first formed by overlapping plates and connecting plates, and the inner triangular surface of the triangular support device is overlapped with the outer surface of the mounting plate inside the high-voltage busbar PT compartment, thereby forming a simple support installation device.

[0010] Preferably, two groups of vertical plates are arranged opposite to each other, and a group of rotating wheels are rotatably installed on the sides.

[0011] Through the above technical solution, by rotating the rotating wheel, the corresponding screw rod is driven to rotate. During the rotation process, the screw rod drives the connecting plate installed with the outer peripheral thread to move, so that the corresponding connecting plate drives the corresponding side plate, upper connecting plate and lower connecting plate to move, thereby adjusting the overlap length and improving the compatibility of the device.

[0012] Preferably, a group of side panels are fixedly mounted on the sides of each group of lap plates.

[0013] Through the above technical solution, after the triangular support device is overlapped inside the high-voltage busbar PT compartment, by rotating the second screw, the second screw drives the corresponding suction cup to perform threaded linear motion on the side of the side plate until the suction cup fits with the inner wall of the high-voltage busbar PT compartment, thereby increasing the stability of the triangular support device.

[0014] Preferably, a group of connecting plates are fixedly installed on the side of each group of the lap plates, and a lower connecting plate is fixedly installed on the bottom end of the other side of each group of the connecting plates.

During the rotation process, the screw rod drives the connecting plate installed through the thread on the outer peripheral surface to move, so that the corresponding connecting plate drives the corresponding side plate, the upper connecting plate, and the lower connecting plate to move, thereby adjusting the length of the overlap and improving the compatibility of the device.

[0020] 2. After the four sets of triangular support devices are fixed, the utility model inserts the insulating baffle body into the top of the four sets of lower connecting plates, rotates the corresponding first screw, and makes the corresponding first screw rotate in the corresponding lower connecting plate to make an upward linear motion until the first screw drives the corresponding fitting block to be fixed to the bottom end of the insulating baffle body, thereby increasing the stability of the insulating baffle body after installation, avoiding the problem of the insulating baffle body falling off during use, and does not require manual support by electricians, thereby increasing the convenience of electricians in the power maintenance process.
