ATEX high bay: energy storage industry safety lighting fundamental technology and application practice

Accompanied by the global energy structure to clean, intelligent transformation, the energy storage industry into a core field to support the development of new energy.

Energy storage power stations, battery production workshops and other scenes are commonly found in hydrogen release, electrolyte leakage and other risks, flammable and explosive environments put forward stringent requirements for industrial lighting.

Explosion proof lamp with its professional explosion proof design, high adaptability and intelligent control features, is becoming the energy storage industry to ensure safe production, enhance the efficiency of operation and maintenance of the core equipment.

First, why the energy storage industry must choose ATEX high bay?

1. explosion-proof security in high-risk environments

Energy storage batteries [such as lithium-ion batteries] in the charging and discharging process probably release hydrogen, when the concentration reaches 4% -75% is very easy to cause an explosion.

ATEX high bay adopts explosion-proof [Ex d] or intrinsically safe [Ex ia] structure, approved high-strength die-casting aluminum shell and double-layer tempered glass protection, completely isolate the internal circuitry from the external hazardous environment, in line with the IECEx/ATEX II 2G Ex db IIC T4 guidelines, can be safely used in Zone 1/2 area, to eliminate sparks or high-temperature surfaces that cause safety accidents.

2. Durable design for extreme working conditions

Energy storage facilities are often faced with high temperatures (battery compartment temperatures can reach over 50°C), high humidity (relative humidity ≥ 90%) and corrosive gases (e.g. electrolyte vapors).

ATEX high bay are approved with IP66/68 protection level and WF2 anticorrosion certification, and the housing is made of nano-ceramic coating and 316L stainless steel, which is resistant to acid and alkali erosion from pH 2-12, and operates stably within the range of -40℃ to 80℃, avoiding the failure of the equipment due to the environmental erosion.

3. Energy saving and whole life cycle cost improvement

Compared with traditional high-pressure sodium lamps, ATEX high bay equipped with high-efficiency LED light source [≥150lm/W], reducing energy consumption by more than 65%, with a long life of up to 100,000 hours.

Its modular design to help high-speed dismantling, with intelligent control systems [such as DALI dimming], can be dynamically adjusted with the energy storage load brightness, reduce ineffective energy consumption, comprehensive operation and maintenance costs reduced by 40%.

Second, ATEX high bay in the energy storage industry core application scenarios

1 battery module production workshop

Lithium battery production process, electrode coating, liquid injection and other processes volatile combustible gases.

Lamps need to be equipped with anti-static coating and 120°wide-angle light distribution design, covering a diameter of 30 meters area, to ensure that there is no shadow lighting, while approved T6 temperature group [surface temperature ≤ 85℃ to prevent hydrogen ignition.

2. Battery compartment of energy storage station

Battery clusters are densely arranged to cause heat dissipation difficulties, ATEX high bay using eddy current cooling ducts and nano thermal conductivity materials to ensure that the chip junction temperature ≤ 100 ℃ at an ambient temperature of 60 ℃, to avoid light degradation. Some models are integrated with gas sensors, which can monitor hydrogen concentration in real time and linkage alarm system.

3. Outdoor energy storage containers and power exchange stations

Outdoor scenes need to deal with rain, snow, salt spray corrosion and vibration impact. Lamps approved IK10 impact resistance level and seismic bracket design, resistant to seismic intensity of 7, with intelligent sensing function [people / cars near the automatic brightening], to enhance the effectiveness of night inspection.

Third, the energy storage industry explosion-proof industrial light technology innovation

1. Intelligent thermal management system

Approved phase change material (PCM) and micro-channel heat dissipation technology, the lamps and lanterns heat dissipation efficiency increased by 50%, the surface temperature is reduced by 20 ℃ compared with the traditional design, suitable for high-temperature confined battery energy storage environment.

2. Optical system and energy efficiency upgrade

Adopting asymmetric lens light distribution technology, the effective illuminance is increased by 35%, spot uniformity ≥ 85%, reducing the interference of scattered light on the battery management system [BMS]. Some models have 3000K-6500K color temperature adjustment to meet the visual needs of different operation stages.

3. Internet of things and remote operation and maintenance integration

With 4G/LoRa communication module, real-time uploading of lamp temperature, power consumption, fault code to the cloud platform, combined with AI algorithms to predict the maintenance cycle, reducing the frequency of manual inspection.

Emergency lighting models have built-in super capacitors, and can continue to light for 120 minutes after power failure, in line with NFPA 110 guidelines.

Fourth, how do energy storage companies choose compliant ATEX high bay?

Certification guidelines: ATEX 2014/34/EU or IECEx approval is required, and the gas group covers IIC [hydrogen].

Environmental suitability: IP68 rating is selected for high humidity areas, 316L stainless steel housing is preferred for corrosive environments.

Energy efficiency indicators: LED light effect ≥ 140lm / W, color rendering index Ra> 80, to ensure the accuracy of the battery appearance inspection.

Intelligent features: preferably with the aid of dimming, fault warning and remote control products, to enhance the effectiveness of energy efficiency management.

FAQ: ATEX high bay common problems answer

Q1: Is it necessary to conduct regular explosion-proof testing for energy storage station lamps and lanterns?

A: Yes. We advocate checking the aging of seals and corrosion of shells every 12 months, and commissioning a third-party organization to re-test the explosion-proof performance every 3 years to ensure compliance with GB 3836 guidelines.

Q2: Does the high humidity environment affect the stability of the lamp circuit?

A: ATEX high bay are approved to encapsulate the driver power supply with vacuum potting process, and the protection level is up to IP68, which can be operated for a long time in the environment of 98% humidity without the risk of circuit short-circuit.

Q3: Does the intelligent dimming function increase the risk of explosion-proof failure?

A: The dimming circuit adopts intrinsically safe barrier isolation technology, the signal transmission energy is limited to less than 30mW, in line with the Ex ia explosion-proof grade, to ensure that no additional sparks generated.
