Abstract

The invention belongs to the technical field of switch cabinets, and in particular relates to a switch cabinet drilling tool and mold and a hole drilling system. The hole-opening tool includes an electric rotating machine, the electric rotating machine is connected with a chuck through a wire, the chuck is connected with a fixed rod, the fixed rod is connected with a rotating head, and the rotating head is connected with a milling cutter, and the surface of the milling cutter is coated with nano-metal paint; the hole-opening mold includes adsorption magnets and The fixed piece fixed by the adsorption magnet, and the fixed piece is provided with a groove; the hole opening system includes a hole cutting tool and a hole punching die. The hole-opening tool has smooth chip removal and low cutting resistance, which can prevent the milling cutter from breaking. The surface of the milling cutter is coated with nano-metal paint, which improves the rigidity of the milling cutter; the switch cabinet hole-opening die facilitates hole-opening work and improves the drilling The opening system is simple and convenient, and can achieve low vibration and spark-free opening of the switch cabinet, avoiding accidents and improving the efficiency of opening.

Description

technical field [0001] The invention belongs to the technical field of switch cabinets, and particularly relates to a switch cabinet opening system. Background technique [0002] Switchgear is a kind of electrical equipment, its function is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each sub-circuit is set according to its needs, such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., and some also have high-voltage rooms and low-voltage rooms. Switch cabinets are equipped with high-voltage busbars, such as power plants, and some are also equipped with low-cycle load shedding to ensure main equipment. [0003] After the switchgear is installed, holes need to be drilled on the switchgea...
