Devices in antiexplosion protection

Damages in electric devices and machines may cause fire in the explosive atmosphere, which is especially evident with older machines and devices. Elektroremont company as an offical representative, by Federal Ministry of energy, coal mines and industry BiH, have its employees and materials for ser­vice of devices in antiexplosion protection (electromotors,transformators,pump agregates, etc.)

Monitoring of devices state in antiexplosion protection and periodic and detailed diagnostics and detecting of damages is one of the mast important task in evaluation system of electromotor as possible general cause of starting the fire and accomplishing of safe and reliable work of older electromotors in areas with explosive atmosphere.   

 

Reparation program of asynchronic electromotors in antiexplosion and protected version includes two groups:
- Diagnostics of antiexlosion protection (IP protection, diagnostics on temperature and insulation system, etc.)
- Diagnostics of rotor cage, stator coil, detecting the eccentricity, measuring of  vi­brations, checking the bearing state, etc.

 



 

 

Defect on coil head of electromotor's stator with power of 45kW, 380V ,980 rpm, caused by break on propeler of ventilator.

 

 

Diagnostics of sticks conduc­tion by "BAKER" instrument on cage rotor of LV electromotor with power of 75kW; 380V and 1480 rpm.
