Изобретение относитс к области электротехники .This invention relates to the field of electrical engineering.
Известно устройство дл определени места, повреждени на лини х электропередачи , включающее фильтр, аттенюатор, усилитель и детектор, присоединенные к высокочастотному каналу каждой фазы, сумматор, суммирующий сигналы по всем трем фазам, функциональный ус1шитель, генератор и блок измерени и индикации.A device for determining location, damage to power lines, including a filter, attenuator, amplifier and detector connected to the high-frequency channel of each phase, an adder, summing the signals over all three phases, a functional aperture, a generator and a measuring and display unit is known.
Недостатком известных устройств вл етс то, что динамический диапазон сигналов, проход щих в эти устройства от мест повреждени линии электропередачи, лежит в ишроких пределах чго существенно усложн ет работу устройства и служит причиной недостаточной точности определени места повреждени линии.A disadvantage of the known devices is that the dynamic range of the signals passing into these devices from the places of damage to the transmission line lies within the limits of which greatly complicates the operation of the device and causes insufficient accuracy in determining the location of the damage to the line.
Целью изобретени вл етс повьпиение точности определени места повреждени путем сужени динамического диапазона амплитуд импульсов, приход щих с линии электропередачи .The aim of the invention is to improve the accuracy of determining the location of damage by narrowing the dynamic range of the amplitudes of the pulses coming from the transmission line.
Это достигаетс тем, что в известное устройство дл определени места повреждени на лини х электропередачи, содержащее входные аттенюаторы, три цепи, кажда из которых состоит из последовательно соединенных фильтра, усилител и детектора, тор, вход которого соединен с выходами детекторов , блок измерени и индикации и первый генератор, введен второй генератор и три модул тора, причем каждый модул тор включен между ;выходом аттенюаторам входом фильтра каждой цепи и соединен с выходами первого и второго генераторов, при этом вход блока измерени и индикаци подг ключей к выходу сумматора.This is achieved by the fact that, in a known device for determining the fault location on power lines, containing input attenuators, three circuits, each of which consists of series-connected filters, an amplifier and a detector, a torus whose input is connected to the outputs of the detectors, a measuring and display unit and the first generator, introduced the second generator and three modulators, each modulator connected between; output attenuators filter input of each circuit and connected to the outputs of the first and second generators, the block input Measurements and indication Getting the keys to the output of the adder.
15 На чертеже дана структурна схема устройства .15 The drawing is a block diagram of the device.
Устройство содержит аттенюаторы 1, модул торы 2, (}ильгры 3, усилители 4, д&текторы 5, сумматор 6, первый генератор 7,The device contains attenuators 1, modulators 2, (} ilgry 3, amplifiers 4, d & tectors 5, adder 6, first generator 7,
20 . генератор 8 и блок 9 измерени и индикации. Каждый из модул торов 2 подключен Между выходом соответствующего аттенюатора 1, и входом соответствующего фильтра 3. Второй вход каждого модул тора под-i ключен к выходу первого генератора 7, а20 . generator 8 and measuring and display unit 9. Each of the modulators 2 is connected Between the output of the corresponding attenuator 1 and the input of the corresponding filter 3. The second input of each modulator is connected to the output of the first generator 7, and
