FACTORY ELECTRICAL SYSTEM
In the factory, most of the equipment and machines that work must use electric power. In order to have a suitable arrangement of equipment in the system, save energy and ensure the operation of the production line, the electrical system in the factory needs to be designed and constructed by a team of experienced engineers.
The electromechanical system is often called the M&E system, which stands for Mechanical & Electrical, consisting of two systems of mechanical and electrical parts. Systems such as lighting, fans, air conditioning, fire protection or water supply and drainage (mechanical parts) must have an electrical energy transmission system, so this item is very important and needs to be carefully designed. For some specialized factory buildings, the electrical system can account for 70-80% of the workload.
The heavy current
The heavy current in the factory electrical system includes items using the main power source with high voltage up to thousands of kV.
The heavy current mainly perform tasks for production, lighting, power distribution and power supply in case of breakdown.
The items of heavy current system include:
- Substation – medium and low voltage capacitors
- Generators, switches.
- Emergency lighting and lighting systems
- Anti-lightning system
- Conductors, power distribution cabinets
- Electrical outlet system
- Grounding system
- Air compressor
- Oil mist collector system (in some specific factories)
- Cable tray ladder, electric cable, underground pipe…
The light current
The light current is used for the purpose of managing and communicating with cable networks and related equipment. The light current includes the following items:
- Management system
- Communication system: telephone, radio, television, internet
- Camera system for surveillance and access control
- Alarm System (PA)
Management of electrical equipment
in the factory by smart system
DELCO has researched and successfully applied the smart factory system, which helps to connect, monitor and store operational data of the factory. Large power consuming equipment such as production lines, air conditioning systems, pumping systems, etc., are monitored for electricity consumption, and automatically turned off when there is no one using, automatically operated according to the factory’s production schedule, thereby saving energy consumption, increasing equipment life, and reducing system maintenance and repair costs.
