Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, in particular to a portable 10kV busbar cabinet phase checking auxiliary tool. Background Art

[0002] When conducting live phase checking on the 10kV busbar cabinet of the electrical system, since the high-voltage live parts inside are closed by the valve baffle, two personnel wearing insulating gloves and protective face shields are required to manually open the valve baffle close to the valve baffle, and then extend the insulating rod to check the phase. Since the operator's safety distance is less than 0.7 meters, the risk of electric shock is high, threatening personnel safety; and the valve baffle is not firmly fixed, and there is a risk of falling when the insulating rod is extended, which can easily cause a short circuit. Or when the operator uses a special phase checking trolley to open the valve baffle, the phase checking trolley is not easy to carry with him, and the power distribution equipment may not be equipped with a special phase checking trolley at all times. This causes inconvenience to the phase checking work. Utility Model Content

[0003] In order to solve the problems of insufficient safety distance caused by manually opening the baffle when the operator is checking the phase, the valve baffle is not firmly opened and fixed, and the phase checking trolley is not portable, the technical problem solved by the utility model is to provide a portable 10kV busbar cabinet phase checking auxiliary tool, which is safe and reliable, simple in structure, easy to carry, and can be operated by one person.

[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] According to an embodiment provided by the utility model, the utility model provides a portable 10kV busbar cabinet nuclear phase auxiliary tool, characterized in that it includes an epoxy resin insulating rod and a telescopic rod. Locking nuts are installed at both ends of the connection between the epoxy resin insulating rod and the telescopic rod to form a telescopic structure. The two ends of the telescopic rod include a pair of guide rails. Spring sheets are installed on the inner side of the guide rails for clamping the left and right support frames in the 10kV busbar cabinet to prevent slipping. A trumpet-shaped protrusion is provided at the opening of the guide rail to facilitate contact with the pulley in the busbar cabinet. A metal sleeve is installed on the outer side of the guide rail for combination with the telescopic rod. The metal sleeve is fixed with a fixing pin at the combination of the telescopic rod. The guide rail is a replaceable structure with two sizes that can be replaced, with heights of 76mm and 88mm respectively, which are respectively suitable for 10kV busbar cabinets with a rated current of 630A-1600A and a width of 800mm and 10kV busbar cabinets with a rated current of 2000A-4000A and a width of 1000mm.

[0006] Furthermore, the utility model adopts epoxy resin insulating material, and the fixing rod of the utility model is preferably but not limited to epoxy resin insulating material.

[0007] Furthermore, the epoxy resin insulating rod, the telescopic rod, and the locking nut form a telescopic structure.

[0008] Furthermore, the guide rail, spring sheet and metal sleeve are an integrated structure.

[0009] The working principle of the utility model is as follows:

[0010] When checking the phase, push the utility model horizontally into the trolley room of the 10kV busbar cabinet, make the guide rails at both ends contact the pulley of the valve baffle mechanism in the 10kV busbar cabinet, and then continue to push it horizontally slowly until the valve baffles in the 10kV busbar cabinet are fully opened, and the spring sheet clamps the left and right support frames in the 10kV busbar cabinet to prevent slipping.

[0011] The utility model has the advantages of reasonable structure, convenient operation, high reliability, good portability, and single-person operation. The utility model can be carried together with the phase checking equipment, which is very convenient for opening the valve baffle when performing live phase checking on the 10kV busbar cabinet of the electrical system, which can greatly reduce the labor burden, increase safety protection, and improve work efficiency.
