Description

Известны устройства дл измерени рассто ни до места повреждени кабел по мостовой схеме, состо щие из реохорда гальванометра и источника тока, к которым подключаетс шлейф из поврежденной и неповрежденной жил кабел .Devices for measuring the distance to a cable damage by a bridge circuit are known, consisting of a galvanometer lead and a current source to which a cable from a damaged and intact cable core is connected.

Описываемое устройство отличаетс наличием в реохорде двух дисков , враидающихс на общей оси, с нанесенными или укрепленными на них щкалами (в метрах).The described device is distinguished by the presence in the reichord of two discs mounted on a common axis, with scals attached or fixed to them (in meters).

На чертеже показана схема предлагаемого устройства.The drawing shows a diagram of the proposed device.

/Ci и К-2 - неподвижные контакты дл присоединени шлейфа; Кз - подвижный контакт реохорда, а и R-2 - одинаковые по величине сопротивлени секции реохорда./ Ci and K-2 — fixed contacts for connecting the loop; Cs is the moving contact of the reichord, and R-2 are the same in magnitude of the resistance of the section of the reichord.

Сопротивление реохорда смонтировано на нижнем поворотном диске , шкала которого имеет 1000 одинаковых делений. При повороте диска сопротивление скользит по неподвижным контактам Ki и /СоКонтакт /Сз укреплен на верхнем поворотном диске, который также имеет щкалу на 1000 делений, совпадающих с делени ми щкалы нижнего диска.The resistance of a reochord is mounted on a lower rotary dial, the scale of which has 1000 identical divisions. When the disk is rotated, the resistance slides over the fixed contacts Ki and / Contact / Sz mounted on the upper rotary disk, which also has a scale of 1000 divisions that coincide with the divisions of the lower disk.

Поворотом нижнего диска относительно неподвижных контактов Ki и 2 сопротивление реохорда (по шкале нижнего диска) в соответствии с длиной кабел , а поворотом верхнего диска добиваютс равенства плеч моста, т. е. положени , когда стрелка гальванометра Г станет на ноль. При этом на шкале верхнего диска (против визира) получают искомую длину поврежденного участка в метрах.By turning the lower disk relative to the fixed contacts Ki and 2, the resistance of the reichord (on the scale of the lower disk) corresponds to the length of the cable, and turning the upper disk achieves equality of the bridge shoulders, i.e. the position when the arrow of the galvanometer D becomes zero. At the same time on the scale of the upper disk (against the viewfinder) get the desired length of the damaged area in meters.

Предмет изобретени Subject invention

Устройство дл измерени рассто ни до места повреждени кабел по мостовой схеме, в которую включаетс шлейф, составленный из поврежденной и неповрежденной жил кабел , отличающеес тем, что с целью непосредственного отсчета по шкале рассто ни до места повреждени в метрах при различных длниах кабел , подвижный контакт реохорда установлен на поворотном диске, имеющем щкалу в метрахA device for measuring the distance to a cable damage site by a bridge circuit, which includes a cable made up of a damaged and intact cable core, characterized in that for the purpose of direct reading on the scale of the distance to the damage point in meters for various cable lengths Reohorda is mounted on a swivel disk with a scale in meters

и расположенном сонцентрнчно другому поворотному диску, также имеющему шкалу в метрах и несмцему расположенные по окружности параллельно дрзг к другу секции сопротивлени реохорда, соприкасающиес с неподвижными контактами, к которым присоедин ютс концы щлейфа с тем, чтобы при измерени х можно было поворотом второго диска предварительно устанавливать по его шкале сопротивление реохорда соответственно длине кабел , а поворотом первого диска определ ть искомое рассто ние по этого диска при равновесии моста.and located sonocentrically to another turntable, also having a scale in meters and nesmtsemu located around the circumference parallel to the SRHG to a friend, the resistance section of the rheochord in contact with the fixed contacts, to which the ends of the plate are attached, so that when measuring it is possible to turn the second disk on its scale, the resistance of a reichord corresponds to the length of the cable, and by turning the first disk, determine the required distance along this disk at the equilibrium of the bridge.
