Improve the availability of power UPS
The availability of food is called UPS, the physical concept is the use of deadline, UPS is the normal execution time and the ratio of the time. According to this definition to improve the availability of UPS, there are two options: one is to increase the UPS MTBF, the second is to reduce Mean Time To Repair MTTR UPS.
UPS power to improve the MTBF of traditional practices that exploit the power switching device specifications and grades, the best control technology, components for logic control to improve the specification and grade, using the most advanced structure of the main circuit, strengthening the management of intelligence and communications capabilities, the strict production technology, improve quality management (ISO9000) and so on. But when the MTBF is increased to a certain effect is not evident. Low MTTR, the effect is very evident. UPS, the practice of reduced MTTR There are several.
1) The general practice is to strengthen the power of UPS, in particular the maintenance of the key elements, adequate spare parts and ensure its integrity, to improve the training of maintenance personnel operational expertise, particularly when the user needs for the acquisition of a manufacturer's sales services UPS (including spare parts, reaction time and rate of repair) conditions make the commitment.
2) + UPS Power Modular Redundancy configured, the circuit in the UPS into several parts, and the structure to connect the module, as the power module (including the rectifier and inverter), the Latitude X300 Series battery modules and communication modules intelligent management .
3) UPS and redundant power configuration of the machine, the UPS in the control circuit can be set as a cap part, can even turn the power concentrated in a structure such as hot-swappable modules. To meet the multiple parallel supply UPS can also be regarded as an inverter for each module, redundant hot backup configuration in case the same thing can be done after the failure of the repair hot or UPS are available directly and all machine functions .
4) Power UPS with an integrated approach to improve the availability of a variety of equipment to meet the needs of the power system. Integrated UPS power system of ideas and principles, the manufacture of electrical equipment and the provision of harmonization and standardization, units of power supply including the integration of structure calculation and standardization of connection, the feed system of equipment and connections (including load PDU) to manage the state of centralized power, and power system links the modular connecting hot-pluggable.
