Open circuit switches for electrical safety procedures and compliance with five electrical safety gold rules for the same equipment

摘要

1. The invention generally refers to the development of systems and devices in the field of electric power engineering. More specifically, the invention refers to devices designed to reduce power risk for control boards or power infrastructure, including one device that complies with five golden rules on power safety. Use electricity to implement electric power safety procedures and five electric power safety gold rulesIncluding: a power-off switch with three mutually exclusive positions, These three positions are: position II power circuit, position 0-circuit and landing position I. This switch consists of the following parts: a controller (1.1) composed of the following parts: a relay device (1.3) connected with the extension device or a relay device (2) directly connected with the body,-A barrier device (1.2) embedded in a relay device (1.1) or a body (2);E. position index (1.4) which is connected with relay device (1.1) or body (2) and can optionally be connected with circuit board; including: 2.1 external electrical terminal or conductive device (2.1.1), output terminal (2.1.2) and external ground terminal (2.2). 2.5.2.1.1. The internal electronic pole or conductor, which combines the mobile input pole (2.5.1.1),Mobile output pole (2.5.1.2),1. Moving earth pole (2.5.3) and short circuit conductor (2.12);There, the electric driver (2.1),a. Networking with electronic variable display (2.3);The display is embedded in the cover of the human body (2);Among them, electric driver (2.5.3) is connected with short circuit electric driver (2.12) and electric driver (2.2) (2.1.2). -The luminous index (2.4) connected with the electric driver (2.1) and embedded in the body cover (2);-The electric driver (2.5) connected with the driving shaft (2.6) in the object;-The driving shaft (2.6) is also connected with an energy transmission device (2.7);a. The force transmission mechanism (2.7) (1.3) connected with the expansion mechanism;-Electronic contacts (2.8),(2.9) connected with drive shaft (2.6) and main body cover (2);-The electrical label position element (2.11) embedded in the relay device (1.1) or the body (2);-A six sided right (2.13.4) interconnected cover (2.13),Left side (2.13.5),After (2.13.6),2.13.3. Below (2.13.3),1. Upper (2.13.2) and front (2.13.1);2.2.2.2.2.2.2.2 and fixing elements (2.14) connecting back cover (2.13.6) and fixing surface.
