Technical Field
[0001] The utility model relates to a security measure for a switch cabinet used for power supply of a public power grid, in particular to a handle moving slot shielding device on a panel of a ring network cabinet mechanism room. Background Art
[0002] The existing ring network cabinets for public power grid power supply must meet the requirements of the IP4X housing protection level of the new national standard, and the ring network cabinet housing must be able to prevent the entry of solid foreign objects with a diameter greater than or equal to 1.0 mm. The isolating switch operation hole, earthing switch operation hole, energy storage operation hole, opening button hole and closing button hole on the mechanism room panel of the ring network cabinet currently produced by the applicant are all provided with plastic covers with padlock holes. However, the inverted T-shaped handle moving slot hole on the mechanism room panel used to control the handle for blocking or opening the internal blocking of the isolating switch operation hole and the earthing switch operation hole must be exposed to ensure that the handle needs to move on it at all times, and it is not easy to close the part of the moving slot hole that is not occupied during the movement of the handle. Therefore, the handle moving slot hole on the mechanism room panel of the existing ring network cabinet currently produced by the applicant has an exposed and unclosed part, which does not meet the requirements of the new national standard. Summary of the invention
[0003] In order to overcome the problem that the handle moving slot hole on the mechanism chamber panel of the applicant's existing ring main unit always has an exposed and unclosed part, which fails to meet the requirements of the new national standard, the purpose of the utility model is to provide an improved handle moving slot hole shielding device on the mechanism chamber panel of the ring main unit, which can overcome the defects of the prior art.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a handle moving slot hole shielding device on the ring network cabinet mechanism chamber panel, comprising a handle installed and matched with the handle moving slot hole on the ring network cabinet mechanism chamber panel, an interlocking L-shaped plate installed on the handle and a tension spring connected between the handle and the ring network cabinet mechanism chamber panel, and its characteristics are: a mounting shaft head is provided on the handle at the rear side of the square cross-section slider, a slot hole baffle is installed at the front of the mounting shaft head, the interlocking L-shaped plate is installed at the rear of the mounting shaft head, a screw hole extending along the axis is provided on the end face of the mounting shaft head, the slot hole baffle plate and the interlocking L-shaped plate are locked on the screw hole by a screw equipped with a gasket, and the size of the slot hole baffle plate is sufficient to cover the area size of the exposed part of the handle moving slot hole when the handle is at any position of the handle moving slot hole.
[0005] The installation shaft head described in the above technical solution can be a square cross-section, and the installation holes of the slotted hole baffle and the interlocking L-shaped plate installed on the installation shaft head can be square holes or rectangular holes.
[0006] The area size of the slot baffle described in the above technical solution can be greater than or equal to 110 mm in length and greater than or equal to 55 mm in width.
[0007] The handle in the above technical solution may be provided with a limiting convex ring on the front side of the square cross-section slider.
[0008] A tension spring hook hole may be provided in the middle of the top side of the slot baffle in the above technical solution, and a tension spring hanging hole may be provided on the panel of the ring network cabinet mechanism room above the slot baffle, one end of the tension spring is hooked on the tension spring hanging hole and the other end is hooked on the tension spring hook hole.
[0009] The control end of the interlocking L-shaped plate described in the above technical solution can be connected in cooperation with the selection rod that blocks or opens the control isolation switch operation hole and the grounding switch operation hole in the ring network cabinet mechanism room.
[0010] The beneficial effect of the utility model is that since the handle is provided with a mounting shaft head on the rear side of the square cross-section slider, a slot baffle is installed on the front part of the mounting shaft head, and the interlocking L-shaped plate is installed on the rear part of the mounting shaft head, the end face of the mounting shaft head is provided with a screw hole extending along the axis, and the slot baffle and the interlocking L-shaped plate are locked on the screw hole by means of a screw equipped with a gasket, and the size of the slot baffle is sufficient to cover the area size of the exposed part of the handle moving slot hole when the handle is in any position of the handle moving slot hole, so no matter where the handle is in the handle moving slot hole, the slot baffle follows the movement of the handle and can cover the original exposed part of the handle moving slot hole, so that the applicant's existing ring network cabinet can meet the IP4X housing protection level requirements of the new national standard. Since a tension spring hook hole may be provided in the middle of the top side of the slot baffle, a tension spring hanging hole may be provided on the panel of the ring network cabinet mechanism room above the slot baffle, and one end of the tension spring is hooked on the tension spring hanging hole and the other end is hooked on the tension spring hook hole, so the handle will be pulled to the upper side of the middle straight line of the handle moving slot when static, so that the isolating switch operating hole and the grounding switch operating hole are in a state of simultaneous internal blocking, so that the isolating switch operating rod and the grounding switch operating rod cannot be inserted into the isolating switch operating hole and the grounding switch operating hole at this time, so as to realize the interlocking function of the isolating switch operating hole and the grounding switch operating hole.
