\"Emergency<\/figure><\/div>\n\n\n\n

Introduction: Substation safety challenges and <\/strong>Emergency exit light explosion proof<\/strong> inevitable choice<\/strong><\/strong><\/h2>\n\n\n\n

Substation as the core hub of the power system, long-term arc flash, SF6 gas leakage, dust explosion and high electromagnetic interference and other multiple risks.<\/p>\n\n\n\n

Ordinary lighting equipment in a high-pressure, flammable environment is prone to sparks or high-temperature surface caused by serious accidents, threatening the safety of equipment and personnel.<\/p>\n\n\n\n

Emergency exit light explosion proof, with their explosion-proof certification design, anti-electromagnetic interference and intelligent emergency function, become the core of substation lighting system safety.<\/p>\n\n\n\n

This paper will start from the substation special environment, analysis of Emergency exit light explosion proof application scenarios, technical guidelines and implementation strategies for the power industry to supply high-reliability lighting solutions.<\/p>\n\n\n\n

First, the substation explosion risk and <\/strong>Emergency exit light explosion proof<\/strong> core value<\/strong><\/strong><\/h2>\n\n\n\n

1. Substation primary safety hazards<\/strong><\/strong><\/h3>\n\n\n\n

Combustible gases and dust environment: SF6 gas leakage [under the action of arc decomposition into toxic, combustible gases, such as SF4, SOF2].<\/p>\n\n\n\n

Transformer oil leakage caused by high temperature vapor explosion [flash point \u2265 140 \u2103]. Coal dust or dust accumulation [coal transmission substation] to form explosive mixtures.<\/p>\n\n\n\n

Risk of electric arc and electric spark: High-voltage equipment failure may generate thousands of degrees Celsius arc, igniting the surrounding combustible materials.<\/p>\n\n\n\n

Extreme electromagnetic environment: Strong electromagnetic interference leads to the failure or malfunction of ordinary lamps and lanterns circuit.<\/p>\n\n\n\n

2. <\/strong>Emergency exit light explosion proof<\/strong> safety protection mechanism<\/strong><\/strong><\/h3>\n\n\n\n

Emergency exit lamp explosion proof approved the following technology to implement intrinsic safety:<\/p>\n\n\n\n

Dust explosion-proof certification [Ex tD]: IP66 sealing design, to prevent the intrusion of coal dust caused by secondary explosion.<\/p>\n\n\n\n

Anti-electromagnetic interference [EMC]: the circuit board adopts shielding and filtering technology, in line with IEC 61000-4 guidelines [anti-interference level \u2265 3].<\/p>\n\n\n\n

Dual-mode emergency power supply: switch to the super capacitor within 0.3 seconds after the main power supply is interrupted, supplying \u2265180 minutes of lighting [in line with GB 17945-2010 guidelines].<\/p>\n\n\n\n

Second. <\/strong>Explosion-proof emergency indicator in the substation core application scenarios<\/strong><\/strong><\/h2>\n\n\n\n

1. High-voltage equipment area and switch room<\/strong><\/strong><\/h3>\n\n\n\n

GIS equipment status indication: install explosion-proof emergency indicator next to gas-insulated switchgear [GIS], approving red\/green dual-color light real-time feedback air pressure abnormalities [such as \u2264 0.4MPa red light alarm].<\/p>\n\n\n\n

Arc light care linkage: integrated light sensor indicator, detecting the arc light within 0.1 seconds to trigger sound and light alarm and start emergency lighting, synchronized cut off the fault circuit.<\/p>\n\n\n\n

2. Transformer and oil storage area<\/strong><\/strong><\/h3>\n\n\n\n

Oil temperature and oil level monitoring: the explosion-proof emergency indicator light is equipped with temperature sensors, triggering yellow warning when the oil temperature at the top of the transformer is \u226585\u2103, preventing overheating and triggering oil explosion.<\/p>\n\n\n\n

Emergency evacuation guidance: the oil storage tank area channel is equipped with direction-indicating explosion-proof emergency indicator lights, with ground illumination \u22655lx in case of fire, and arrows guiding the safe exit.<\/p>\n\n\n\n

3. Control room and outdoor facilities<\/strong><\/strong><\/h3>\n\n\n\n

Uninterrupted lighting in the main control room: Emergency exit light explosion proof to help UPS power supply access, in the main power supply and backup power supply failure, start the self-supply battery power supply.<\/p>\n\n\n\n

Outdoor terminal box lighting: -40 \u2103 ~ +70 \u2103 wide temperature Emergency exit light explosion proof, protection level IP68, resistant to rain, snow and salt spray corrosion.<\/p>\n\n\n\n

Third, substation explosion proof emergency indicator selection and technical guidelines<\/strong><\/h2>\n\n\n\n

1. Certification and compliance requirements<\/strong><\/strong><\/h3>\n\n\n\n

Explosion-proof certification: must be approved ATEX [II 2G Ex d IIC T4 Gb], IECEx<\/a> or CNEx certification, adapted to SF6 gas environment Zone 1 area.<\/p>\n\n\n\n

Power industry standards: comply with DL\/T 593-2016 high-voltage switchgear standards and GB\/T 17626 electromagnetic compatibility requirements.<\/p>\n\n\n\n

2. Fundamental technical parameters<\/strong><\/strong><\/h3>\n\n\n\n

Light source performance: LED light source light efficiency \u2265 130lm\/W, color temperature 5000K [cold white], color rendering index Ra>80, accurate identification of meter readings and equipment status.<\/p>\n\n\n\n

Emergency range: According to GB 51309-2018 guidelines, the control room and channel need to be equipped with Emergency exit light explosion proof with a range of \u2265 180 minutes.<\/p>\n\n\n\n

3. Intelligent function upgrade<\/strong><\/strong><\/h3>\n\n\n\n

SCADA system integration: Approve IEC 61850 protocol to access the substation automation system, real-time uploading of lamp health status and battery capacity data.<\/p>\n\n\n\n

Adaptive dimming strategy: automatically adjust the brightness according to the ambient light and equipment operation mode [such as maintenance\/normal], energy saving more than 25%.<\/p>\n\n\n\n

Fourth, <\/strong>Emergency exit light explosion proof<\/strong> installation and maintenance specifications<\/strong><\/strong><\/h2>\n\n\n\n

1. Specialized installation requirements<\/strong><\/strong><\/h3>\n\n\n\n

Explosion-proof electrical wiring: the use of flame retardant high temperature cable [such as YJV], junction box using Ex e increased safety structure, grounding resistance \u2264 4\u03a9.<\/p>\n\n\n\n

Anti-vibration design: When installing around the transformer, install anti-vibration bracket [amplitude \u2264 0.5mm] to avoid loosening of the structure due to mechanical vibration.<\/p>\n\n\n\n

2. Full life cycle maintenance strategy<\/strong><\/strong><\/h3>\n\n\n\n

Monthly inspection: use infrared thermography to detect the surface temperature of the lamps and lanterns [\u226480\u2103], clean the dust in the heat sinks and test the emergency switching function.<\/p>\n\n\n\n

Annual in-depth inspection: commission a third-party organization to test the gap between the blasting surface [\u22640.15mm], insulation resistance [\u22651000M\u03a9] and electromagnetic immunity.<\/p>\n\n\n\n
