Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As it is shown in figure 1, a kind of defibrillator repid discharge capacitance module, including electric capacity 10 and divider resistance 20, at least provided with two electric capacity 10, connecting between electric capacity 10, each electric capacity 10 is provided with divider resistance 20.

In Fig. 1, C1, C2, C3, C4, Cn are series connection, and resistance R1, R2, R3, R4, Rn are the divider resistance of electric capacity.

The resistance of described divider resistance 20 is 100 kilo-ohms��400 kilo-ohms.

As shown in Figure 2 and Figure 3, described electric capacity 10 includes positive paper tinsel 1, negative paper tinsel 2, electrolytic paper 3, shell 4, sleeve pipe 5, extraction 6, electrolyte 7, and positive paper tinsel 1 is the high pressure Waste Acid From Hua Cheng Foil running through perforation type, and negative paper tinsel 2 is the negative paper tinsel more than 5V voltage, and electrolyte 7 is isosebacic acid ammonium.

Ratio >=15% of isosebacic acid ammonium in electrolyte 7, the ratio of Azelaic Acid hydrogen ammonium is 1��5%. Adopt isosebacic acid ammonium (i.e. 1.7 ammonium sebacate), ratio >=15%. Increasing Azelaic Acid hydrogen ammonium, the oxide-film to increase electric capacity forms speed, and voltage is more few more at high proportion, for 400WV, it is possible to adopt the ratio of 3%

The present embodiment is the capacitance module adopting extraordinary 6 400V820UF composition, is combined into the electric capacity of 2000V136UF, and the energy of electric capacity can according to W=1/2CU²It is calculated as 272 joules, as needed bigger energy, it is possible to adjust the energy of electric capacity. Divider resistance 20 is typically chosen 400K divider resistance in other circuit general, and for this type of extraordinary special charge and discharge capacitance, the divider resistance of optional 100K.

Data below is by the characteristic difference between relatively more extraordinary 400V470UF and common 400V470UF.

400V470UF35*50GX and VXS parameter comparison

Can be clear from table, extraordinary 400V470UF electric capacity, leakage current, internal resistance, loss are all significantly less than common 680UF electric capacity under discharge frequency 50HZ, charging interval T=T1+T2, (T1 refers to be charged to time of pressure to T1=CV/ [I fill-I leakage], T2 refers to that electric leakage drops to rational degree, general I leakage��1C, and after T, electric capacity allows electric discharge). Therefore, I leakage is more big, and charging rate is more slow, it addition, after charging voltage to pressure, discharge current=V/ (internal resistance+external resistance), therefore internal resistance is more little, and discharge current is more big, and the energy transfer efficiency of electric capacity is also more high.

This utility model, owing to have employed electric capacity reverse protection and perforated foil, therefore, there is no need to protection diode. Owing to have employed perforation formed aluminum foil, electric capacity inherent due to the reverse potential caused that discharges only small, generate heat also only small, electric capacity can be allowed next time to carry out quickly discharging, solution conventional capacitive easily discharges the mechanism of inefficacy.
