Akwụkwọ GRV8-03X ruo 08X series nke ime eme voltage monitoring voltage relay:
Nke GRV8-03X ruo 08X series na-enye onye anya maka ihe gbasara ime eme voltage na akwụkwọ voltage relay, na-enwe ike ime eme dị mma na adaptability dị elu:
1. Power management maka ụdị mobile devices na special vehicles:
Iji enyere ime eme three-phase power dị mma maka onye a na-eji engineering equipment, ụdị agricultural machinery ( dịka harvesters, tractors), refrigerated transport vehicles na ụdị mobile equipment ndị ọzọ, na-enye usoro na ezi dị mma na environment power supply dị ọjọọ na agbanyeghị ( dịka generator power supply ma ọ bụ temporary power access), na-enweghị ihe dị ka shutdown ma ọ bụ damage dịka voltage abụọ.
2. Equipment rotation direction protection:
Ime eme phase sequence nke three-phase power supply nke dị mma na-enye detection dị elu nke phase sequence errors (nke ga-enwere ike inebi motor ibe)
Na-enye control signals iji enweghị mechanical damage, production accidents, ma ọ bụ safety incidents nke ga-eme n'ime mechanical equipment ibe.
3. Automatic Switching System (ATS) maka Primary and Backup Power Supply:
N'akụkọ dịka data centers, hospitals, ma ọ bụ critical production lines nke factories, na-enye ime eme status nke normal (primary) power supply na emergency (backup) power supply ( dịka generators). N'otu ọhụrụ main power supply fails ( dịka voltage loss, undervoltage, overvoltage, phase loss), na-enye signal nke dị mma iji drive switching device, seamless ma ọ bụ brief interruption load iji switch to backup power supply, na-enye continuity nke power supply.
4. Motor and power load protection:
Real time monitoring nke three-phase power supply maka electric motors na other important power loads. N'otu ọhụrụ phase failure, na-enye immediate detection na output alarm ma ọ bụ cut off control signal, na-enweghị motor overheat na burn out n'ime single-phase operation, na-enye protection valuable equipment assets.
5. Industrial production lines and mechanical equipment protection:
Widely used n'ime ụdị industrial automation production lines, pumps, fans, compressors na ụdị equipment ndị ọzọ, jako front-end voltage protection unit, iji enweghị equipment shutdown, production interruption ma ọ bụ component damage n'okwu unstable grid voltage (overvoltage, undervoltage) ma ọ bụ phase loss.
Nke GRV8-03X ruo 08X series three-phase voltage monitoring type voltage relay product features:
1. High precision true effective value measurement:
Site na true effective value measurement technology, na-enye accurate voltage measurement results (accuracy ≤ 1%) olee n'ime non sinusoidal voltage conditions containing harmonics, truly reflecting the state of the power grid.
2. Wide voltage adaptability and wiring flexibility:
Na-enye 8 adjustable rated voltage levels nke na-enwe ike adapta standard grid voltages n'ime ụwa na ụlọ ndị ọzọ. Supporting both 3-phase 3-wire na 3-phase 4-wire (3L/3N) wiring methods iji mee ike site na diverse on-site requirements.
3. Excellent anti-interference performance:
Internal circuit na-enwe professional anti harmonic design optimization, na-enwe strengthening for high interference industrial environments ( dịka near frequency converters na high-power rectification equipment), na-enweghị harmonic interference na-enye stability na reliability nke ime eme.
4. Intuitive status indication:
Equipped with high brightness LED indicator lights, na-enye clear display nke current working status nke relay ( dịka power supply, faults, alarms, etc.), making it easy for on-site personnel to quickly identify the system's operating status.
5. Ultra compact design:
Adopting an ultra-thin design with a width of only 18mm, na-enye greatly saves installation space inside the control cabinet. Supports standard 35mm DIN rail installation, with easy and quick installation and disassembly, suitable for high-density wiring applications.
