Power frequency online UPS relies on intelligent operation and maintenance, the core of which is to change from periodic blind inspection and emergency repair afterwards to remote centralized monitoring and predictive state maintenance , and to reduce costs from four dimensions: labor cost, spare parts cost, failure loss and energy consumption:
1. Remote centralized monitoring to reduce the labor cost of on-site inspection
Relying on SNMP/Modbus/4G/Ethernet, the multi-site and multi-power UPS are unified on the cloud/local platform, and the voltage, current, transformer temperature, load and battery status are checked on the APP and Web side for 24 hours. Abnormal initiative to push the alarm, without frequent visits to the site by the operation and maintenance personnel, remote computer rooms can achieve few people/unattended, greatly reducing travel and on-site labor input, and also support remote viewing of logs, parameter adjustment and remote diagnosis. Many small problems can be directly and remotely located without going to the door.
2. Intelligent battery monitoring and life prediction to reduce the cost of battery spare parts and replacement
Power frequency UPS supporting battery is the main consumable; Intelligent BMS monitors internal resistance, voltage, temperature, SOC/SOH, AI analyzes aging trend and accurately predicts failure time. No longer replace batteries in batches according to a fixed number of years, only replace truly aging monomers to avoid waste caused by early replacement; At the same time, it has temperature compensation charging and automatic floating charging management, which can delay battery aging, prolong battery life and reduce battery purchase frequency.
3. Predictive fault early warning to reduce the loss of emergency repair, spare parts and downtime
Continuously collect data such as temperature rise and running time of transformers, capacitors, fans and power devices, identify hidden dangers such as abnormal temperature rise, device deterioration, circulation and uneven load in advance, and pre-warn faults. The traditional "broken and then repaired" passive repair is changed into on-demand state maintenance: the door-to-door goal is clear, the first repair rate is higher, and the high service fee for invalid door-to-door and emergency repair is reduced; At the same time, reduce the business losses caused by sudden downtime (such losses are much higher than the cost of operation and maintenance itself).
4. Intelligent energy consumption and load optimization, saving electricity (operation energy consumption cost)
The intelligent operation and maintenance platform counts the load rate, loss and harmonics, and cooperates with the ECO economic model, intelligent cooling speed regulation and parallel load sharing optimization to reduce the power frequency machine's own loss on the premise of power supply quality and safety; Multi-machine parallel scenarios automatically balance loads, avoiding inefficient operation of single machine with light load and reducing long-term power consumption costs.
5. Operation and maintenance of digital ledger to reduce management cost
The system automatically saves alarm, charge and discharge and maintenance records, and automatically generates weekly and monthly reports without manual paper records and manual statistics; The asset ledger and maintenance plan are automatically generated, which is convenient for batch asset management, reduces the workload of data collation and asset inventory, and facilitates the traceability of maintenance quality and avoids excessive maintenance (unnecessary regular in-depth maintenance) expenses.
To sum up in a word: Less on-site running, less battery replacement, less emergency repair, optimized power consumption, and reduced the total operation and maintenance expenditure on the premise of ensuring high reliability of industrial frequency UPS .
