Keyword: Power source of lash-up of derv generation set reserves power source
One, set a principle
In design of high-level building power supply, setting derv generation set must answer below apparent what circumstance above all, we mention from grade of high-level architectural bear first:
The fire control water pump in building of ① high level, prevent the fire control such as illume of smoke evacuation establishment, fire lift, lash-up to use phone, according to " civil building designs the high level fire prevention standard " (GB50045-95)9.1.1 regulation, building of a kind of high level should bring power supply of demand of one class bear, building of 2 kinds of high levels should press power supply of demand of 2 class bear.
② is pressed " civil building is electric the design is normative " (JGJ/T16-92)3.1 regulation, the bear of a lot of place in high-level building is one class bear, hall of the banqueting hall of hotel of consistent, 2 class, recreation, advanced guest room, kitchen, main office architectural is guest ladder electric power, main illume of the office, assembly room, the illume of postal service hall of large department store; The negative charge that still has a few place is 2 class bear, be like electric power of ladder of the automatic staircase of department store, guest, architectural of ministry, provincial office is main illume of the office, assembly room. Particularly main negative charge still is contained in one class bear, what if significant traffic key position, communication hub and classics are commonly used,a large number of personnel at important international activity center is public centralized one class bear.
One class bear should by two power source in all report. 2 class bear allows when the condition when also appropriate by two loop power supply, belong to fire control to use 2 class bear of report especially, the power supply of two loop demand that should press 2 class negative charge. This shows, high-level building is taller to the dependability requirement of power supply, ask power supply of two power source. Accordingly, the principle that considers to set derv generation set is as follows:
① can offer the high-level structure of 2 independent power source to electrified wire netting, had satisfied by the standard one, the requirement of 2 class bear, in principle can not establish derv generation set. But, build to particularly important high level (if exceed a high level to build) , its interior contains particularly main negative charge, when should considering overhaul of system of one power source or fault, the severe case that system of another power source malfunctions again, should set derv generation set to make lash-up power supply commonly right now.
