Energy-saving light emitting diode (LED) integrated sign with accident lighting and equipment nameplate functions

Abstract

The invention discloses an energy-saving light emitting diode (LED) integrated sign with accident lighting and equipment nameplate functions and belongs to the field of lighting devices. A sign body is a transparent light guide panel; an equipment number is marked on the transparent light guide panel; LED light-emitting devices are arranged around the transparent light guide panel; the light-emitting surfaces of the LED light-emitting devices face the transparent light guide panel; the LED light-emitting devices are connected with a power supply of an emergency accident lighting device of a transformer substation through wires. When the emergency accident lighting device of the transformer substation is started, the LED light-emitting devices are energized to emit light to lighten the equipment number on the transparent light guide panel, convenience is provided for operators in reading an equipment number nameplate mark, and an accident emergency lighting source is provided for a part where the sign is located. The transparent light guide panel can be used for displaying equipment number words and can be used as a planar light source to lighten a surrounding environment, so that the misoperation of the operator can be avoided, lighting energy is utilized to the greatest extent, the emergency accident lighting device and the equipment number nameplate mark are integrated, and double effects are achieved.

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...

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
