Energy-saving led accident lighting and equipment nameplate integrated sign

Abstract

An energy-saving LED accident lighting and equipment nameplate integrated signboard belongs to the field of lighting devices. The body of the sign is a transparent light guide panel, on which the equipment number is marked; LED light-emitting devices are arranged around the transparent light guide panel; the light-emitting surface of the LED light-emitting device faces the transparent light-guide panel; Power connections for emergency lighting. When the substation accident lighting device is started, the LED light-emitting device is electroluminescent, illuminating the equipment number on the transparent light guide panel, helping the operator to quickly and correctly read the equipment number nameplate mark, and providing accident emergency lighting for the place where the sign is located light source. Its transparent light guide panel can not only display the text of the equipment number, but also serve as a plane light source to illuminate the surrounding environment, which can avoid the misoperation of the operating personnel and maximize the use of lighting energy, making the emergency lighting device and the equipment number plate mark two In one body, it plays a dual role.

Description

technical field [0001] The invention belongs to the field of lighting devices, in particular to an LED lighting device used for emergency lighting and equipment nameplate lighting. Background technique [0002] In the high-voltage electrical room of the substation, each high-voltage equipment has a numbered nameplate mark, and in the high-voltage electrical room, according to the design requirements, conventional lighting fixtures are also installed. [0003] In the daily operation of the substation, according to the provisions of the "Safety Operation Regulations", the "operation ticket" system has been implemented, that is, before operating a power transformation and distribution equipment, it is necessary to write in advance the equipment object and operation content to be operated. and the operation steps, after being reviewed by the supervisor on duty, the operator takes the written operation ticket to the high-voltage electrical room, one person reads out the operation...

AI Technical Summary

Problems solved by technology

[0006] When a large-scale unexpected power failure occurs in the entire power grid system (such as a sudden power failure of one of the two incoming power supplies) or the substation encounters multiple equipment failures at the same time (such as heavy rain, sudden water inflow in the substation) accident), when the substation needs to perform emergency switching operations on multiple power transformation and distribution equipment, whether the serial number and nameplate of the equipment can be read quickly and correctly often becomes the bottleneck restricting the speed of accident handling, and it is also easy to cause misoperation accidents the cause of

[0007] In order to solve the above problems, it is a solution to increase the illuminance standard of the high-voltage electrical room by setting more indoor lighting fixtures, but the side effect is that the power consumption of daily lighting is greatly increased. In addition, in the summer high temperature season , the increase of high-power lighting fixtures has also led to an increase in the temperature of the high-voltage electrical room, which increases the workload of the cooling device (axial fan or air conditioner, etc.) There are many disadvantages such as increased maintenance workload of lighting fixtures, increased number of lamp accessories, and shortened service life of cooling devices, which will even affect various detection and monitoring equipment in the high-voltage electrical room (such equipment is usually electronic circuit equipment, and its electronic components higher sensitivity to ambient temperature), and the addition of conventional indoor lighting fixtures in substations does not increase / improve the illuminance of accident lighting in high-voltage electrical rooms in emergency situations, which still cannot solve the problem in emergency situations (mainly referring to conventional indoor In the case of power failure of the lighting system) the problem of rapid and correct reading of the equipment number nameplate mark
