Complectation
Frequency converter of ventilation fan of FCVF type is intended for automatic maintenance of specified booster fan (BF) capacity in networks of 690 V with frequency of 50 Hz at coal mining enterprises gas and/or dust hazardous.
The device is made with spark-safe remote control circuits, it has the explosion-proof design and protection marking PB Exd[ia]ia I. The shell structure provides ingress IP54 protection according to GOST 14254-96.
It provides:
- Operational localand remote control;
- possibility to connect two motors to one converter;
- operating or standby mode of drive operation;
- connection to main optical communication link;
- electrical protections* (27,50, 59, 79, etc.);
- preliminary insulation testing of outgoing lines (BRU mode);
- protection against loss of control;
- control of air leakage from the ventilation pipe;
- control of vibration accelerations of BF motor;
- protection against BF shaft seizure.
Operating conditions:
- Ambient air temperature -10...+35°C;
- relative air humidity up to 100% at temperature +35°C;
- absence of sharp jerks and shocks;
- dust content in ambient air is not more than 1000 mg/m3;
- working position in space is horizontal, deviation from
- the working position up to 15 degrees in any direction is allowed.
Reliability indicators:
- Average time between failures - not less than 8000 h;
- established resource beforefirst major overhaul - not less than 65000 h;
- average total service life - not less than 15 years;
- mean recovery time - no more than 2 hours.
