Abstract
Изобретение относитс к электросв зи. Цель изобретени - повышение точности контрол . Устройство содержит источник 1 напр жени , пороговый блок 2, блоки управлени 3 и 4, блоки отключени 5 и 6, состо щие из элементов И 7, блок задержки 8, блоки смещени 9 и блок коммутации 10, содержащий элементы коммутации 11, состо щие каждый из диода 12 и реле 13. При открывании блока управлени 4 "плюс" диодов 12 соедин етс с источником 1. От него через смещенные в пр мом направлении диоды 12, обмотки всех реле 13 и блоки смещени 9 подаетс обратное смещение на все остальные диоды 12. Происходит зар д паразитных емкостей обратносмещенных диодов 12 до напр жени , близкого к напр жению источника 1. Когда открываетс блок управлени 3, то разр жаютс паразитные емкости диодов 12 и монтажа. При этом ток разр да этих емкостей проходит по цепи: источник 1 - блок управлени 4 - элементы коммутации 11 - паразитные емкости - блок управлени 3 - источник 1. 1 ил.The invention relates to telecommunications. The purpose of the invention is to improve the accuracy of control. The device contains a voltage source 1, a threshold unit 2, control units 3 and 4, disconnection blocks 5 and 6, consisting of elements AND 7, a delay unit 8, bias units 9 and a switching unit 10 containing switching elements 11, each from diode 12 and relay 13. When opening the control unit, 4 "plus" diodes 12 are connected to source 1. From it, through the forward-shifted diodes 12, the windings of all relays 13 and offset blocks 9, reverse bias is applied to all other diodes 12 . The parasitic capacitances of the reverse-biased diodes 12 are charged to A voltage close to the voltage source 1. When the control unit 3 is opened, the parasitic capacitances of the diodes 12 and the installation are discharged. In this case, the discharge current of these capacitors passes through the circuit: source 1 - control unit 4 - switching elements 11 - parasitic capacitances - control unit 3 - source 1. 1 sludge.
