What is a maintenance power supply?
Thread Content
Article 6.1.7 of the Coking Regulations: Maintenance power supplies shall be provided in areas at risk of explosion and fire. I’m not quite clear about the concept of a maintenance power supply; I hope experts can provide some guidance: 1. What is a maintenance power supply? 2. How should the maintenance power supply be configured to meet safety requirements? Thank you.
Our facility is equipped with maintenance power boxes and emergency repair power boxes, which are used as a power source for regular maintenance and repairs that can be carried out without shutting down the system. The maintenance power boxes are generally distributed evenly throughout the facility; no power is supplied to them under normal conditions. The emergency repair power boxes are located in relatively safe areas of the facility, and power can be supplied to them by going through the necessary procedures for temporary power use when it is needed
The maintenance power supply box is a type of low-voltage distribution equipment; it is suitable for environments with high levels of dust and moisture corrosion, and is widely used in various industries such as steel metallurgy, power generation, ports, shipbuilding, railways, urban light rail systems, the chemical industry, and construction. It is generally equipped with knockout holes of various diameters to facilitate wire insertion and removal, to suit various wiring schemes.
