Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, and specifically relates to an insulated busbar wrapping actuator, particularly a wrapping actuator suitable for installation on a robotic arm that can also perform non-linear wrapping. Background Technology

[0002] Insulated busbars are one of the key equipment (materials) in power transmission and transformation systems. They are mainly used in my country's power construction projects as conductor connections between power grid transmission lines and substation transformers, jumpers in transmission lines, connecting conductors in power equipment, and as current conductors in high-current DC de-icing devices. They are a new type of conductor that replaces traditional rectangular, channel, rod-shaped busbars and flexible conductors, and play a vital role in the safe and reliable operation of power transmission and transformation systems and power equipment. They are usually composite shielded insulated copper (aluminum) tube busbars, with insulation tape wrapped around the copper or aluminum tube busbar, which can be achieved by corresponding wrapping robots.

[0003] For example, patent application number CN202421297466.8 discloses a fire-resistant mica tape wrapping device, including a base plate. A circular shell is provided at the top center of the base plate, and a wire harness plate is provided on one side of the circular shell. A recessed area is provided on the outer edge of one side of the circular shell, and a ring gear is adapted to be provided in the recessed area. Both ends of one side of the ring gear are equipped with winders for placing mica tape rolls, and a cover is fixed to the opening of the recessed area of ​​the ring gear. A square shell is provided on the side of the ring gear away from the wire harness plate, and a slot is opened in the center of the square shell and a cavity is provided inside. Pressure rollers for pressing and consolidating the mica tape are symmetrically arranged on the inner circumference of the slot.

If the two winders are directly mounted on the ring gear, the inner diameter of the ring gear needs to be large (to ensure the distance between the two winders), and the difference between the inner and outer diameters of the ring gear needs to be large (so the outer diameter is large) to ensure the installation space for the winders.

[0007] 3. Due to the weight and size of the wrapping actuator, it is usually fixed in the existing technology and is not suitable for installation on the robotic arm. Summary of the Invention
