FIELD: electricity.SUBSTANCE: invention is related to energy-containing stand-by power sources actuated by ignition of pyrotechnical electrodes of battery by joining elastic igniters. Pyrotechnical composition of elastic igniters includes the following components, in wt %: barium chromate 62-70, zirconium powder 26-30, slag stabilising agent - zirconium dioxide 2-4 and binding agent - dispersed chrysotile asbestos with dispersion degree of 0.2-2mm in quantity of 2-4. The solution is targeted to stabilisation of shape of sheet elastic igniters at burning, thermal conductivity improvement for formed slag and provision of simultaneous ignition of pyrotechnical electrodes of the stand-by power supply source due to stabilised rate of igniters burning and optimised qualitative and quantitative composition of the above electrodes. Slag dispersion is practically excluded in elastic igniters due to formation of gas-permeable coke residue with porosity of 10% and minimised gas release during burning.EFFECT: extension of application area.2 tbl, 5 ex |
