Description

Energy-saving LED emergency lighting and equipment nameplate integrated signage

technical field

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

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.

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 content on the operation ticket (commonly known as "singing ticket") according to the steps, and the other repeats the corresponding operation content and Carry out the corresponding operation according to the repeated content to prevent misoperation of other power transformation and distribution equipment. In the middle of this process, there is a step of "confirming the number of the equipment being operated", that is, it is necessary to read the number plate mark of the equipment to be operated. confirm.

Since the existing conventional lighting fixtures are usually hanging high bay lamps installed on the top of the high-voltage electrical room, which adopt point light source distribution, due to the straight-line propagation characteristics of light, the lighting intensity of different areas in the entire high-voltage electrical room (also known as is the illuminance) with a large difference.

The substation is usually equipped with emergency lighting devices, the number of which is greatly reduced compared with the number of conventional lighting fixtures, and it is only used as emergency passageway indicator lighting in emergency situations. In this case, the illuminance in the high-voltage electrical room is lower, making The number plate mark of the equipment is more difficult to be identified and confirmed in an emergency, and additional mobile lighting devices (such as hand-held lighting fixtures) are usually required for auxiliary lighting.

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 incentives.

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 high-voltage electrical rooms (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, and it still cannot solve the problem in emergency situations (mainly referring to conventional indoor lighting). In the case of power failure of the lighting system) the problem of rapid and correct reading of the equipment number nameplate mark.

The technical problem to be solved by the present invention is to provide an energy-saving LED accident lighting and equipment nameplate integrated sign, which constitutes an emergency lighting device at the operating point of the operator by setting a light source composed of LED light-emitting devices on the equipment number nameplate , which can ensure that the equipment number and nameplate mark can be read quickly and correctly without negatively affecting the ambient temperature, which can prevent and avoid the occurrence of "misidentification" of operating equipment accidents, and is conducive to energy saving and consumption reduction in substations and reduced operation. It helps to ensure the correctness and safety of the operation of power transformation and distribution equipment in emergency situations.

The technical solution of the present invention is to provide an energy-saving LED accident lighting and equipment nameplate integrated sign, including a sign body marked with equipment numbers and a frame for fixing the sign, characterized in that: the sign body is transparent light guide The panel is marked with a device number on the transparent light guide panel; at least one set of LED light emitting devices is arranged around the transparent light guide panel; the light emitting surface of the LED light guide device faces the transparent light guide panel; the The LED light-emitting device is connected to the power supply of the emergency lighting device of the substation through a wire.

When the substation accident lighting device starts to start, the LED light-emitting device is electroluminescent, and the illumination light is cast on the transparent light guide panel to illuminate the equipment number on the transparent light guide panel, so as to help the operator identify the equipment number nameplate The sign can be read quickly and correctly, and the accident emergency lighting source is provided for the place where the sign is located.

Specifically, the LED light-emitting device is arranged on or in a fixed frame around the transparent light guide panel.

The light emitting surface of the LED light emitter faces the side end surface of the transparent light guide panel.

Further, the above-mentioned signboard is marked with the equipment number on the light-guiding transparent light-guiding panel, and the transparent light-guiding panel can not only display the text of the equipment number, but also serve as a plane light source to illuminate the surrounding environment.

Further, the light sources of the LED light-emitting devices are concentrated on the transparent light guide panel, which ensures a clear indication of the equipment number and avoids misoperation by operators, and the light sources of the LED light-emitting devices are reasonably distributed within the operator's operation. In terms of points, the lighting energy is used to the maximum extent, so that the emergency lighting device and the equipment serial number and nameplate mark are two in one, playing a dual role.

Compared with prior art, the advantages of the present invention are:

1. The LED light source is installed on the equipment number plate, so that the transparent light guide panel can not only display the equipment number text, but also serve as a plane light source to illuminate the surrounding environment, killing two birds with one stone;
