Check and maintain the main switch cabinet (MDB, DB).
Check and maintain MDB cabinet, what is DB ?
Maintenance of electrical control cabinet (MDB) and electrical sub-cabinet (DB) is to check and clean inside the cupboard and around the cabinet with only specialized equipment for electrical equipment, such as using electrical contact cleaner to remove oil stains. and dirt residues on the circuit breaker This spray has specific properties that are used to clean electrical appliances. and electrical equipment safely due to its electrical insulating properties Quick-drying, leaving no residue after maintenance, maintenance within the electrical control cabinet (MDB) and electrical sub-cabinet. (DB) should be performed by a professional on a regular basis. At least twice a year and around the cabinet should be cleaned at least once a month to prevent damage that may occur from short circuit events.
Scope of inspection and maintenance of MDB, DB cabinets
1. Verify that the installation of electrical equipment is correct according to the standards.
2. Check the operation system of the electrical equipment.
2.1 Check the condition of the cable and check the size and suitability of the wire size.
2.2 Check the magnetic contactor by checking the coil and contacts.
2.3 Check the operation of the control system both Auto/manual
2.4 Check the Fuse Base and HRC Circuit Breakers.
2.5 Check the Capacitor Bank system (Test Capacitor Bank)
2.6 Check the size of the ground wire and ground conditions
2.7 Check the condition of the sub-switchboard enclosure.
2.8 Check nameplates and single-line photographs.
3. Main Distribution Board
3.1 Test the insulation value of the electric wire (Insulation Test)
3.2 ACB Test, Contact resistance Test, Under Over Voltage Test
3.3 Check the condition and measure the capacitor (Capacitor Test)
3.4 Measure the insulation value (Mega Ohm Test)
3.5 Measure the dielectric strength of the busbars.
3.6 Check the grounding and measure the resistance
4. Clean electrical cabinet and equipment and tighten the nut and apply compound on the contact area.
5. Thermal imaging (Thermoscan) before and after maintenance.
6. Summary report of inspection and maintenance results with suggestions
what you will get
