Experiment condition: load 4 groups, often organize electric current 16A, resistance 15 Ω, rated power 10KW, experiment bearing power 4KW, total load 64A, supply voltage 250V, PDU busbar cross-section amasss 9mm
2., ring busbars 4+2.5mm
2
Experimental subjects: compatible socket exports and exports the highly reliable PDU of mid-through bus both sides distribution with cable.
Experimental technique: to be detected respectively by temp.-sensing wire without paper temperature rise recorder and record the temperature of plug, PDU shell, input cable crust, copper sheet (shell fragment) and environment, until every temperature reaches capacity.
Record form is as follows:
Table 1
Table 1 is corresponding with Figure 28.
Table 2
Table 2 is corresponding with Figure 29.
Can find out that temperature rise is the highest at about 20K according to table 1 and 2, the 45K required in " People's Republic of China (PRC) communication industry standard YD/T2063-2009 ".
Experimental data is had to obtain: the present invention connects low-resistance, reliable, lasting, stable and temperature rise is little, eliminates risk on fire.
