Description

Technical Field

[0001] The invention relates to the technical field of switch cabinet phase checking equipment, in particular to an adjustable switch cabinet phase checking auxiliary tool. Background Art

[0002] After the construction, renovation or overhaul of the enclosed switch cabinet, it is necessary to use instruments or other means to check whether the phase and phase sequence of the two power supplies or loops are the same before power is supplied. When performing a phase check on a fully enclosed switch cabinet, you first need to try to open the isolation baffle of the switch cabinet to expose the upper and lower static contacts of the switch cabinet. The upper and lower contacts are respectively connected to the bus power supply at this end and the bus power supply from the other end of the line. The phase check instrument is inserted into the upper and lower contacts to directly contact the two power supplies to obtain phase sequence information. Power can only be supplied after the phase sequence is checked to be consistent; At present, we have two methods available. One is to use a "phase-check trolley". At present, the switch cabinets in substations and switches in community distribution rooms are basically not equipped with "phase-check trolleys", and the cabinet models are different; the second is that the test personnel all use unconventional means to open the baffles. The operation requires the staff to lean into the cabinet, use insulating rods and other tools, tie the driving crank arm of the cabinet door, and open the upper and lower isolation baffles at the same time, which makes it difficult to maintain a safe distance from the live equipment; and the top plate position of the switch cabinet phase-check auxiliary tool is fixed, resulting in the top plate cannot completely match the switch position inside the switch cabinet when facing different models of switch cabinets, thus affecting the practicality of the device. In addition, the existing switch cabinet phase-check auxiliary tools are large in overall size and poor in portability, which also limits their scope of application.

[0003] Therefore, an adjustable switch cabinet phase auxiliary tool is needed to improve the above problems. Summary of the invention

When the fixing piece 413 moves horizontally, the fixing piece 413 applies a thrust to the rotating sleeve 411 through the connecting rod 412, thereby making the rotating sleeve 411 rotate on the outer wall of the fixing protrusion 410 and apply a horizontal thrust. The fixed protrusion 410 drives the opening shell 403 to move horizontally, and at the same time, a limited sliding groove 404 is provided on the outer wall of the opening shell 403, wherein the limited sliding groove 404 is inclined 45 degrees relative to the horizontal plane, and a positioning rod 401 is slidably connected to the inner wall of the limited sliding groove 404, and the positioning rod 401 passes through the limited sliding groove 404 to limit the sliding of the opening shell 403.

[0027] The mounting block 301 is mounted at the top corner of the mounting plate 2. A sliding rod 302 is mounted on the outer wall of the mounting block 301. The outer wall of the sliding rod 302 is slidably connected to the sliding shell 303. When it is needed, it is only necessary to pull the sliding shell 303 to make the sliding shell 303 slide horizontally on the outer wall of the sliding rod 302. When the inner cavity side wall of the sliding shell 303 and the sliding rod 302 are attached together, it is only necessary to rotate the sliding shell 303, so that the sliding shell 303 rotates with the sliding rod 302 as the center of the circle, and the sliding shell 303 is unfolded, and then the mounting plate 2 and the sliding shell are connected. A magnetic adsorption block 304 is installed between 303 and on the outer wall of the mounting plate 2, wherein the magnetic adsorption block 304 is provided with two groups and is respectively located on the outer wall of the mounting plate 2, and the magnetic adsorption block 304 and the sliding shell 303 are connected in a magnetic manner, and then the sliding shell 303 is magnetically adsorbed on the outer wall of the magnetic adsorption block 304 for fixation.
