Description

Technical Field

[0001] The present invention belongs to the technical field of electrical equipment, and in particular relates to an insulating plugging cap assembler and detacher for a cable port of an electrical equipment and a method for using the same. Background Art

[0002] To install an insulating plug cap (hereinafter referred to as the plug cap) on a 10KV electrical equipment cable port, first apply insulating grease (hereinafter referred to as the grease) to the cap opening. Grip the top of the plug cap, align it with the cable port (hereinafter referred to as the port), and rotate it several times clockwise to complete installation. After completing work on the electrical or equipment cabinet (hereinafter referred to as the electrical cabinet), grip the top of the plug cap, rotate it several times counterclockwise, and pull to remove it.

[0003] The plug cap is made of rubber, creating a tight seal against the port and generating significant friction. Excessive grease can fill the gap between the cap and the port during removal, creating a seal and vacuum that makes it difficult to remove. Insufficient grease can create significant friction during installation, making installation and removal more difficult and cumbersome. Even manually rotating and installing three to five plug caps can cause arm pain, requiring a break before continuing. Alternatively, multiple people may be required to perform the installation and removal tasks simultaneously, making manual installation extremely laborious.

[0004] To carry out relevant work on an electrical cabinet, it is necessary to install and remove the plugging cap 15 times, which is entirely dependent on pure manual operation and the operation volume is large.

[0005] Due to the limited installation space, installation can only be done one-handed, and it is often the case that the screw thread cannot be tightened even after multiple turns. This is because the grease fills the gap between the plug and the port, forming a closed space, and there is air in this space. Single-handed installation is an intermittent operation. When the hand is released and replaced, the squeezed air can push the plug away from the screw thread, resulting in installation failure.

[0006] It takes an average of about 2 minutes to install or remove a plug, which is inefficient.

[0007] In summary, the use of existing technology to install the plug cap is a purely manual primitive method, which requires a lot of manual work, is time-consuming and labor-intensive, has low efficiency, and has a high installation failure rate. Summary of the Invention
