Description
Technical field
The present invention relates to the data center machine room technical field, particularly a kind of power supply test macro for machine room.
Background technology
For the quality and performance that guarantees that data center machine room is paid, at present a lot of newly-built machine rooms all can adopt the mode of fictitious load Reality simulation equipment electricity consumption to come the performance of the whole machine room electric power system of integration test, and this process is integration test.And a lot of electromechanical equipments in the data center machine room also need bringing onto load to move to do periodic maintenance, UPS(Uninterruptible Power Supply for example, uninterrupted power source) battery and generator etc. are so all can regularly use fictitious load or directly with real load the machine room electric power system is tested and safeguard after machine room formally comes into operation.But, along with the continuous increase of data center machine room scale and improving constantly of reliability requirement, test and the job requirement of safeguarding also constantly promote, and unified machine room electric test and O﹠M system all provides testing requirement to whole machine room lifetime process in the urgent need to a cover.
Yet in the prior art, newly-built large-scale data center machine room all adopts the combination of 10KV high-voltage generator and UPS that the machine room information technoloy equipment is powered and back-up protection is provided.Generally can a fixing 10KV high pressure fictitious load be installed as the load for testing of generator, as shown in Figure 1 at first stage of construction for newly-built large-scale machine room.And, generally can not increase again fixing low pressure fictitious load in order to save cost, but need to rent fixing low pressure fictitious load in the integration test phase and test low-voltage power supply system (comprising power distribution cabinet, UPS and battery), and after machine room is enabled, just directly load to battery discharge with information technoloy equipment.
The shortcoming that prior art exists is that its load characteristic of 10KV high pressure fictitious load causes it only to use to the 10KV high-voltage generator, tests so need to rent in addition the low pressure fictitious load for machine room low pressure 220V/380V electric power system, has increased cost.And because the low pressure fictitious load of renting is not fixedly connected with, need to seeks the fictitious load putting position at every turn when testing and be connected a large amount of cables, take time and effort.After machine room is enabled, directly come electric power system is tested with information technoloy equipment, there are like this two problems, at first use real information technoloy equipment test, because there is larger risk in the uncertainty of battery in the tested electric power system, secondly because load of actual information technoloy equipment often changes and and calculated load have very large gap, the discharge current that causes every primary cell is all different and to calculate electric current much smaller, the performance that can not truly reflect battery, and the time of battery discharge also can improve therefore and greatly, increase the test duration, strengthened maintainer's working strength.
