Anti-misoperation indicating and marking device for ring main unit

Abstract

The invention discloses an anti-misoperation indicating and marking device for a ring main unit. The device comprises an operation room and an operation panel, an operation mechanism is installed inside the operation room, the operation mechanism is provided with a divide-shut brake switch on the operation panel, the operation panel is provided with a silk-screen circuit or silk-screen pattern used for displaying and feeding back a divide-shut brake switching signal, the silk-screen circuit or silk-screen pattern is provided with a gap, the operation mechanism is rotationally provided with a divide-shut brake indication piece which is connected with the divide-shut brake switch, and when the divide-shut brake switch is in a brake dividing state, the divide-shut brake indication piece can be rotated to the gap and communicated with the silk-screen circuit. In the anti-misoperation indicating and marking device, two kinds of different technical schemes of the silk-screen circuit or the silk-screen pattern are adopted, the silk-screen circuit and the silk-screen pattern can both be effectively in the space environment of the ring main unit, the state of the divide-shut brake switch can be effectively observed by operating staff, and the misoperation under the electrified circumstance can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to a ring network cabinet indicating and marking device Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. [0003] Due to the high voltage in the ring network cabinet, it is generally necessary to carry out grounding treatment when operating the ring network cabinet. In order to prevent misoperation and reduce safety accidents, the ring network cabinet is often equipped with panel protection devices. However, the protection signs on some panels are not perfect, especia...

Problems solved by technology

However, the protection signs on some panels are not perfect, especially when the light is insufficient or the viewing direction is deviated, the opening and closing signs on the operation panel are not clear, which makes misoperation occur from time to time, and the five defenses cannot be effectively realized. There is a huge hidden danger to the personal safety of operators
