The electrical system is one of the key factors that determine the operational efficiency and safety of a factory's production process. With the constant operation of machinery and equipment, the electrical design must not only ensure a stable power supply but also strictly comply with technical standards. So, what standards should be considered when designing the electrical system for a factory?
In this article, BIC will explore the important standards that must be followed in factory electrical design, from international standards to Vietnamese regulations, ensuring safety, efficiency, and cost savings for businesses.
The electrical system in a factory plays a crucial role in ensuring the safety of both people and equipment. Adhering to electrical technical standards minimizes the risk of fire, electrical shorts, and technical malfunctions. A properly designed electrical system not only guarantees worker safety during operations but also protects machinery from damage caused by unstable voltage. This reduces the risk of harm to both people and property, while also enhancing production efficiency for the business.
Electrical design standards not only focus on safety but also contribute to optimizing the operational efficiency of the factory. A system designed according to standards will ensure sufficient load capacity for all equipment without causing overloads or sudden power outages. This allows continuous operation, preventing production interruptions, thus increasing productivity and minimizing the cost of resolving issues. The performance of the entire electrical system heavily depends on strict compliance with these standards.
When the electrical system is designed and installed following technical standards, businesses not only ensure safety but also save on long-term operational costs. A properly standardized electrical system reduces frequent malfunctions, helping to save on maintenance and repair costs. Moreover, optimizing energy efficiency also helps reduce electricity costs and prolong the lifespan of equipment. Therefore, adhering to electrical design standards is not only a mandatory requirement but also provides significant financial benefits for businesses.
The electrical design drawing standards for factories include guidelines on how to present, symbolize, and arrange the electrical system in an industrial environment. The drawings must strictly follow technical regulations regarding the design and installation of electrical systems, and meet the following criteria:
The electrical drawing must use the correct technical symbols as required and clearly represent the scale of details compared to reality. This helps the construction team easily interpret and follow the technical requirements, speeding up the construction process and minimizing errors during installation.
The factory electrical system design drawing must meet the following technical standards:
- TCVN 5699-1: 2010: Safety requirements for household electrical appliances.
- TCVN 8241-4-2: 2009: Electromagnetic compatibility (EMC) standards for electrostatic discharge immunity, compliant with IEC 61000-4-2: 2001.
- TCVN 7922: 2008: Regulations on symbols used in electrical system drawings, compliant with IEC 60617: 2002.
- TCXDVN 319: 2004: Grounding system standards for industrial factories.
- TCVN 3715: 82: Standards for complete transformer stations with a capacity of 1000kVA, 20kV voltage.
In addition to electrical design standards, the drawings must also focus on arranging proper emergency exits to ensure worker safety in emergency situations. You can explore detailed regulations on factory emergency exits to ensure the design meets all safety requirements.
When designing the electrical system for a factory, engineers will rely on the electrical schematic to calculate and evaluate the efficiency of the entire system. This ensures that equipment such as fans, ventilation systems, lighting, etc., operate consistently and continuously at the projected capacity. Detailed calculations ensure that the electrical system operates effectively while minimizing risks, ensuring safety and long-term production efficiency.
The electrical engineering team will select appropriate equipment to avoid overloads or power fluctuations. This is crucial to prevent machinery malfunctions and reduce operational instability. Selecting the right equipment not only ensures more efficient system operation but also extends the lifespan of machinery, saving on future maintenance and repair costs.
Engineers not only ensure that the project is completed on schedule but also prioritize worker safety. The lead engineer will be responsible for arranging and providing the necessary safety gear for each construction team, ensuring all personnel work in a safe environment.
During the design process, engineers will also carefully calculate the indices and electrical load paths to prevent the risk of electrical shorts, ensuring absolute safety for workers. Therefore, adhering to safety standards is not just a commitment but an essential factor during the construction and operation of the electrical system in factories.
The final key criterion to ensure that a factory electrical design drawing meets the requirements is the accurate calculation of the amount of electricity the business will consume. The drawing must clearly reflect these parameters to help the factory operate smoothly without facing issues due to overload or power shortages.
Additionally, the design should propose energy-saving solutions, such as using energy-efficient devices or reasonably distributing power to different areas. This ensures that the business not only operates efficiently but also saves on long-term electricity costs, creating favorable conditions for production.
First, engineers will collect information from the client, including the electrical installation site, factory size, and the number of devices to be used. The technical team will then conduct an on-site survey to verify and compare the data provided by the client to ensure accuracy in the design process.
Designing the high-voltage network requires clearly defining the area for the high-voltage system, the method for connecting electrical cables, the type of poles used, and the safety distance between power lines. Additionally, load capacity calculations are necessary to avoid electrical safety risks.
Similar to the high-voltage system, the low-voltage network design must carefully calculate the placement of electrical poles, cable routing, and the safety distance between the high-voltage and low-voltage networks. This ensures that the electrical systems do not conflict and operate efficiently.
The electrical design drawing must comply with standards for the lighting system, including light intensity, direction, color temperature, and the placement and number of lights in each area. The goal is to ensure optimal lighting efficiency throughout the factory.
Depending on the factory's load capacity, capacitor banks will be arranged to enhance the electrical system's efficiency, reduce malfunctions, and increase the lifespan of electrical equipment.
After the design drawing is completed, the investor will monitor, inspect, and evaluate the system’s completeness, including safety requirements. If the drawing meets all standards, the construction process will commence.
Adhering to electrical design standards in factories not only ensures worker safety but also helps the electrical system operate efficiently, stably, and long-term. A standard-compliant electrical design will contribute to cost optimization, risk reduction, and ensure smooth production progress for the business.
