Description
В известных сейсмических зондах с питанием на несущих частотах гас щее сопротивление -в цепи питани накала ламл и зонда устанавливаетс в верхнем приборе, что позвол ет питать его одножильным бронированным кабелем. Однако щсе остальные ниже расположенные приборы остаютс соединенными трехжильным кабелем, питание которым требует большого количества изолированных свечных вводов в зонде, что значительно снижает производительность труда.In the known carrier-powered seismic probes, the damping resistance is in the supply circuit of the glow of lambles and the probe is installed in the upper device, which allows it to be fed with a single-core armored cable. However, the rest of the downstream devices remain connected by a three-core cable, the power supply of which requires a large number of insulated spark plug leads in the probe, which significantly reduces labor productivity.
В предлагаемом многоканальном сейсмическом зонде благодар расположению гас щего сопротивлени в цепи накала ламп зонда в нижнем приборе, резко сокращаетс количество свечных Вводов в зонде (например, в дес тиканальном зонде до 19), что дает возмол ность питать его одножильным бронированным кабелем.In the proposed multi-channel seismic probe, due to the location of damping resistance in the glow circuit of the probe lamps in the lower instrument, the number of spark plug inputs in the probe (for example, in a ten-channel probe to 19) is sharply reduced, which makes it possible to feed it with a single-core armored cable.
На чертеже показана блок-схема 1Ш1тани предлагаемого зонда.The drawing shows a block diagram of 1SH1 of the proposed probe.
В каждом из приборов /-6 нити электронных ламп соединены параллельно , причем в цел х уменьщени сопротивлени высоким частотам , параллельно им включены конденсаторы по 1 мкф. В нижнем приборе 1 установлен дроссель Др высокой частоты дл предотвращени замыкани на корпус прибора и гас щее сопротивление R, поднимающее напр жение питани зонда до 1.20-130 в. Подбором сопротивлений , устанавливают В этом же пределе анодное напр жение :в каждом .приборе.In each of the devices / -6, the filaments of the electron tubes are connected in parallel, and in order to reduce the resistance to high frequencies, in parallel with them are included capacitors of 1 microfarad. In the lower unit 1, a high frequency choke is installed to prevent shorting to the instrument housing and damping resistance R, raising the probe supply voltage to 1.20-130 V. The selection of resistances, set In the same limit anode voltage: in each device.
Предмет изобретени Subject invention
Многоканальный сейсмический зонд с питанием на несущих частотах , отличающийс тем, что, с целью сокращени количества .свечных вводов в зонде, применено гас щее сопротивление в цепи накала ламп зонда, установленное в нижнем приборе зонда.A multichannel seismic probe with power at carrier frequencies, characterized in that, in order to reduce the number of end connections in the probe, damping resistance is applied in the glow circuit of the probe lamps installed in the lower probe device.
