Warning and anti-falling knife switch for power system

Abstract

The invention provides a warning and anti-falling knife switch for a power system and relates to the technical field of a system. The knife switch comprises a switch base, wherein an engine oil reducing pipe is fixedly connected with the middle of the switch base, a first piston rod is movably connected with a left side of the reducing pipe, and a first spring connected with an outer side of the first piston rod in a sleeving mode is fixedly connected with an inner bottom wall of the switch base. The knife switch is advantaged in that the reducing pipe and a warning block are matched for use,during closing, the knife switch is rotated rightwards, the knife switch downwards extrudes a second piston rod, under the action of the hydraulic principle of the reducing pipe, the first piston rodmoves upwards and pushes a lever, the first spring is stretched, a warning block rotates and is received in the switch base, when power failure occurs, the first spring drives the lever to rotate anddrives the first piston rod to move downwards, the warning block rotates out of the brake base to prompt that an electric brake is not switched on, and thereby the warning effect is achieved, maintenance personnel can visually know a state of the electric brake conveniently, and the labor amount is reduced.

Description

technical field [0001] The invention relates to the technical field of systems, in particular to a switch blade for a power system with warning and anti-falling off. Background technique [0002] The power system has a corresponding control system in each link to regulate and protect the electric energy, which has ensured that users can obtain safe, stable and high-quality electric energy. [0003] The current switch is one of the electric energy control systems. The connection or disconnection of electric energy is controlled by the switch. The current switch is only composed of a switch knife, a conductive sheet and a gate seat. There is no basis for judging whether the switch is in use. Closing needs to be judged by the power switch, which increases the workload of maintenance personnel, and most of the current switch is directly clamped, without anti-dropping device, the switch is easily separated from the conductive sheet, and the stable operation of electric energy can...
