FIELD: weapon and ammunition.SUBSTANCE: invention relates to time fuse devices (TFD) for shells of multiple artillery rocket systems with cassette or separable warhead payloads (WHPL). The essence of the offered invention is that into the time fuse containing the input inductive coil, the rectifier, the power capacitor, the inertial contactor, the electronic time device connected to the safety and executive mechanism the low frequency filter with the cut-off frequency not exceeding a half of frequency of the unit carrier signal, the voltage limiter protecting from over voltage of the power capacitor and the voltage stabiliser caused by changes of level of induced voltage at the inlet induction coil of the fuse during installation, depending on the relative positioning of the transmitting coil of the installer and the input coil of the fuse, and additional limiters of control signals of the electronic temporary device, providing limitation by amplitude of control signals. The induction coil has branches which through the rectifier, the low frequency filter and the voltage limiter are connected to the input "Installation" and through the integrating circuit to the additional input "Reset" of the electronic temporary device and through the diode to the power capacitor and the voltage stabiliser input. The integrating circuit consisting of the resistor and the capacitor with the time constant considerably exceeding the duration of the setting impulse provides selection of the signal "Reset" of the electronic temporary device.EFFECT: invention allows to improve efficiency of multiple collective.3 cl, 3 dwg |
