[0002] When the relay protection major is conducting secondary inspections of AC and DC circuits such as "busbar protection, line protection, main transformer protection, fault recording, low-frequency load reduction, and stabilization control devices", secondary safety measures must be implemented before work to reliably isolate the maintenance equipment from the operating equipment. The existing secondary safety measures are implemented by using insulating tape to cover the operating circuit on the terminal block and wrap the removed secondary wires in the air. During the work process, due to the influence of the adhesiveness of the insulating tape, or due to collisions and improper operations by operators, the insulating tape may fall off and accidentally touch the operating circuit, causing the operating switch to trip by mistake, and the operator may be electrocuted, which is a serious safety hazard.

[0003] The reliability of the existing protective cover in implementing secondary safety measures is not high, and operators need to repeatedly stick insulating tape, which wastes working time and cannot meet normal working needs. Summary of the invention

[0006] A handle-type operating handle is vertically fixed on the upper surface of the reference plane, and a rectangular inward hollow opening box is vertically fixed on the lower surface of the reference plane. Multiple open cylindrical grooves are provided on the outer walls on both sides of the rectangular inward hollow opening box, and a warning operating surface is provided at the connection between the open cylindrical groove and the reference plane.

[0007] Preferably, a warning sign “Secondary safety measures, no touching” is provided on the outer wall of the warning operation surface.

[0008] Preferably, the handle-type operating handle, the rectangular inwardly hollow opening box body, the open cylindrical trough body, the warning operating surface and the reference surface are all made of red non-visual insulating tough material and are integrally formed.

[0009] Preferably, the handle-type operating handle is in a semi-fan-shaped shape with a handle.

[0010] Preferably, the open cylindrical trough body includes a plurality of open insulating box bodies in the shape of a cylinder.

[0011] Compared with the prior art, the utility model has the following beneficial effects: firstly, the isolation protective cover can physically and completely and reliably isolate the operating circuit, and is suitable for AC and DC terminal blocks.

[0012] Secondly, the removed secondary wires of various diameters can be placed on both sides of the isolation protective cover, preventing the possibility of accidental contact or misoperation of the running circuit to the greatest extent.

[0013] Furthermore, the isolation protective cover is provided with obvious warning signs to prevent people from accidentally touching it.

[0014] The multifunctional isolation protective cover of the secondary safety terminal block reduces operational risks, improves operational efficiency, has low economic costs, is easy for personnel to operate, and is reusable, so it has broad prospects for application and promotion.
