Explosion proof pilot light in the battery factory lighting the fundamental role and application guide

Introduction: Battery factory lighting special needs and Explosion proof pilot light to get the solution

In the battery manufacturing industry, safety and efficiency is the core demand in the production process. As battery production involves flammable and explosive chemicals [such as lithium, electrolyte, etc.] as well as dusty environments, ordinary lighting equipment is difficult to meet the safety guidelines, and even probably become a safety hazard.

At this time, Explosion proof pilot light as a professional safety lighting equipment, by virtue of its explosion-proof, corrosion-resistant, high stability features, into the battery factory lighting system core components.

In this paper, we will discuss in-depth Explosion proof pilot light in the battery plant application scenarios, technical advantages, as well as selection proposition, for industry users to supply practical reference.

First, Explosion proof pilot light in the battery production environment core value

1 battery plant potential explosion risks and lighting safety challenges

Battery production workshops often have the following risks:

Combustible gases and dust: lithium-ion battery assembly process probably release hydrogen or other combustible gases; electrode materials [such as graphite, metal powder] dust is easy to form explosive mixtures.

High temperature and high pressure environment: Charge/discharge test, welding and other processes may generate high temperature or electric sparks.

Corrosive substances: electrolyte leakage is likely to corrode the ordinary lamps and lanterns shell and circuit.

Traditional lighting equipment does not have explosion-proof performance, once the short circuit or overheating, it is very easy to cause an explosion or fire.

2. Explosion proof pilot light how to ensure production safety

Explosion proof pilot light approved the following design to implement intrinsic safety:

Explosion-proof housing and sealing structure: made of aluminum alloy or stainless steel, combined with explosion-proof [Ex d] or increased safety [Ex e] design, to ensure that the internal electrical sparks will not ignite the external environment.

Corrosion-resistant surface treatment: approved epoxy resin coating or IP66/IP67 protection level, resisting electrolyte, acidic gas erosion.

Low heat generation and efficient heat dissipation: LED light source with intelligent temperature control system to reduce the surface temperature of the device to avoid becoming an ignition source.

Second, Explosion proof pilot light in the battery factory in the specific application scenarios

1. Production workshop area instructions and safety warnings

Equipment status marking: install Explosion proof pilot lamp on the fundamental equipment such as charging and discharging equipment, liquid injection machine, etc., and approve red/green light to prompt the operation status to avoid misoperation. Emergency evacuation guidance: install explosion-proof emergency indicator lights at workshop passages and safety exits to ensure high-speed evacuation in case of emergency.

2. Hazardous area classification lighting

According to international standards [such as IEC 60079], the battery factory needs to divide the production area into different explosion hazard levels [Zone 1/Zone 2]. Explosion proof pilot light lamps need to comply with the corresponding zone certification requirements:

Zone 1 [high hazardous area]: explosion-proof lamps and lanterns, applicable to electrolyte storage area, liquid injection workshop Zone 2 [low hazardous area]: safety-enhanced lamps and lanterns, applicable to assembly line, packaging area.

3. Intelligent management and energy saving

Modern Explosion proof pilot lamp can be integrated with IOT module to implement remote control, brightness adjustment and fault warning, reduce maintenance costs and improve energy consumption. For example, linkage with the factory DCS system, according to the environmental lighting automatically switch the work mode.

Third, how to choose the right battery factory Explosion proof pilot light ?

1. Certification guidelines and compliance

International certification: Ensure that the product is approved ATEX, IECEx ou UL certification for explosive environments. Protection level: Prioritize IP65 and above, adapt to the humid and dusty environment of the battery factory.

2. Light source performance and technical parameters

Advantages of LED light source: long life [more than 50,000 hours], low energy consumption, no strobe, reduce maintenance frequency. Color temperature and color rendering: advocating the choice of 5000K neutral white light, color rendering index [Ra] > 80, to ensure the visual clarity of the work.

3. Customized design to meet the needs of the scene

Chemical-resistant coating: For the risk of electrolyte leakage, polycarbonate shell or fluorocarbon coating can be customized. Modularized structure: easy maintenance and replacement of accessories to reduce downtime.

Fourth. Installation and maintenance of Explosion proof pilot light best practices

1. Professional installation to avoid potential safety hazards

Qualified explosion-proof electrical engineers to implement wiring to ensure reliable grounding, cable sealing. Avoid drilling or modification on the explosion-proof shell to prevent damage to the explosion-proof performance.

2. Regular maintenance to extend equipment life

Monthly inspection: Clean the dust on the surface of the lampshade and check whether the seal is aging. Annual inspection: commission a third-party organization to test the explosion-proof performance and insulation resistance.

Fifth. Answers to Common Problems [FAQ

Q1：What is the primary difference between Explosion proof pilot lamp and ordinary indicator?

A: Explosion proof pilot light approved special structural design [such as explosion-proof chamber, seals] to prevent the internal spark ignition of the external explosive environment, while the ordinary lamps and lanterns do not have this protection.

Q2：Whether all areas of the battery factory must use Explosion proof pilot lamp ?

A：According to the hazardous areas. Non-hazardous areas [such as office] can use ordinary lamps and lanterns, but the production workshop, storage area must use explosion-proof certified products.

Q3：Explosion proof pilot light lamp life is often how long?

A: LED light source explosion-proof lamp life of up to 5-10 years, depending on the application environment and maintenance frequency.

Q4: How to determine whether the Explosion proof pilot light explosion-proof grade compliance?

A: Check the product nameplate on the Ex logo [such as Ex d IIB T4], and ask for a third-party certification.

Conclusion: Investment in Explosion proof pilot light, guarding the safety and efficiency of the battery factory!

In the battery manufacturing industry increasingly fierce game today, approved the deployment of high standards Explosion proof pilot light, enterprises can not only avoid the risk of safety accidents, but also enhance production continuity and reduce long-term operation and maintenance costs.

Choose a professional supplier, combined with the actual needs of the factory to customize the solution, will become a critical step in the intelligent upgrading of the battery factory.
