ATEX street light in the battery factory lighting applications – explosion-proof safety and energy efficient double guarantee

First, the special needs of battery factory lighting and ATEX street lamps adaptability

Battery manufacturing environment [such as lithium-ion battery production line, electrolyte storage area] often exists hydrogen, organic solvents, vapours and other flammable and explosive gases, as well as electrode material dust [such as graphite, metal powder].

Traditional lamps and lanterns due to electric sparks or high surface temperature may cause explosion risk, and ATEX street lamps approved by the European Union ATEX directive certification [such as Ex d IIC T6 Gb guidelines], designed for Zone 1, Zone 2 [gas] and Zone 21, Zone 22 [dust] hazardous environments designed to effectively isolate the internal arc and sparks, and to control the surface temperature is lower than the ignition point of the gas [such as the T6 group ≤ 85 ℃], into the safety of the battery factory. Rigid lighting needs.

Second, ATEX street light in the battery factory core advantages

1. Intrinsically safe and explosion-proof certified ATEX street lamps with explosion-proof shell and safety-enhancing circuit design, the internal arc or spark is completely isolated, and approved strict temperature control [such as T6 group ≤ 85 ℃], to meet the Ⅱ C gas [such as hydrogen], Ⅱ dust [such as metal dust] environmental requirements.

For example, a power battery factory to replace the ATEX street lamps, lighting equipment caused by the safety hazards to zero.

2. Comparison of energy-efficient and long-life energy consumption: 80W LED ATEX street light, for example, has a luminous flux of 9,600 lumens, which is 68% more energy-efficient than the traditional 250W high-pressure sodium lamps, and the annual energy saving of a single lamp is more than 1,800 kilowatts.

3. Lifespan advantage: LED light source life of more than 50,000 hours, combined with IP66 protection and corrosion-resistant design (e.g., epoxy resin spraying), reducing electrolyte corrosion caused by equipment damage, maintenance costs reduced by 60%.

4. Enhanced environmental adaptability to prevent dust and corrosion: Aluminium alloy housing is approved for salt spray testing for more than 1,000 hours, and is resistant to electrolyte volatile acidic gases and metal dust environments.

Wide temperature range operation: support -40 ℃ to +60 ℃ extreme temperature, suitable for battery factory low-temperature drying workshop and high-temperature formation process area.

Intelligent control and emergency functions integrated with Internet of Things technology, to help remote dimming, fault warning and emergency lighting [0.3 seconds after the power failure to switch the backup power], to meet the UL 924 emergency guidelines, to ensure the safety of the production line evacuation in the event of a sudden power failure.

Third. Typical scenarios of battery factory and ATEX street light solution

1. Dust explosion-proof demand in electrode production workshop: Ex tD A21 IP65 dust-proof ATEX street lamps are selected to cover the electrode coating, roller pressing and other process areas, with luminous efficacy ≥120 lm/W, to avoid the risk of ignition and explosion caused by the accumulation of graphite dust.

2. Electrolyte storage and injection area gas explosion-proof requirements: the configuration of Ex d Ⅱ C T6 ATEX high-pole lamps, installation height of 6-8 metres, covering a radius of 20 metres, luminous flux 12,000 lumens, to ensure that the high-speed diffusion of hydrogen gas area lighting safety.

3. High-temperature tolerance in the chemical formation and aging test workshop: adopting copper-aluminium composite heat dissipation structure to ensure that the temperature rise of the lamps is ≤15℃ under 50℃ environment, avoiding accelerated light decay.

Case of transformation: a head battery enterprise will replace 200 sets of traditional metal halide lamps with 80W ATEX street lamps, the annual electricity cost savings of 520,000 yuan, accident response time shortened by 40%.

Fourth, selection and installation specifications

Selection points explosion-proof level to match the environment [such as Ⅱ C gas selection Ex d Ⅱ C T6, dust selection Ex tD A21]. Priority selection of light efficiency ≥ 120 lm / W and improved heat dissipation models, to extend the life of the application.

Installation and maintenance of cable sealing: the use of explosion-proof flexible tube connection, junction box sealing level of IP54, to prevent electrolyte infiltration.

Regular inspection: monthly cleaning lamp surface dust, semi-annual testing of radiator performance and circuit insulation.

Fifth. Future Momentum: Intelligent and Modular Upgrade

Gas monitoring linkage: Built-in combustible gas sensor, automatically enhances ventilation and triggers sound and light alarms when the concentration exceeds the standard.

Optical storage integration: integrated solar panels and energy storage systems, off-grid power supply, to meet the needs of zero-carbon factories.

Modularised design: High-speed replacement of light source and drive module, increasing maintenance efficiency by 50%.

FAQ: Common Problems of ATEX Street Lights

Q1：How to choose the explosion-proof level of ATEX street light for battery factory?

A: According to the type of ambient gas [such as Class IIC corresponding to hydrogen] and dust characteristics [such as A21 metal dust] to determine, advocating the implementation of hazardous area classification by professional organisations.

Q2：Does ATEX street light help to use in humid environment?

A: Yes, the IP66 protection level can withstand high-pressure water rinsing, and is suitable for wet environments in electrolyte workshops.

Q3: Will the intelligent control system increase the initial cost?

A：Initial investment increases about 12%, but approved energy saving and reduce manual inspection, 1.5-2 years can recover the extra cost.
