Describes how to apply good mine electrical equipment

Describes how to apply good mine electrical equipment, electrical equipment for mines common principles and maintenance techniques, as well as common fault diagnosis and  mcb circuit breaker elaborate. Electrical equipment found to be faulty, we must first ask how is the failure to see the fault condition can not be too anxious to repair. If it is a new device that we should first look at the circuit schematic and structural characteristics of the device, according to the relevant rules for power transformers . Remove the front to fully understand the function of each electrical components, the location, as well as how to connect the relationship with other devices. If there is no assembly diagram, to the demolition of the same sketch, but also well marked. First look at the device is not there a more obvious cracks or burn marks, defects, etc., and then check its interior. To determine before disassembly rather than external fault fault then disassemble the machine. If the blind demolition, not only bad repair equipment, but also the more likely the more serious repairs.
