Description

Известные схемы KOMiMyxamni распределительных устройств на 3-10 кв с одной системой сборных шин со стационарным оборудованием индивидуального отключени  фидеров имеют такие недостатки, ка:; сложность нроизводства ремонтных работ и высока  стоимость изготовлени  раснределнтельного устроГ1ства.Known KOMiMyxamni switchgear for 3-10 kV with one busbar system with stationary equipment for individual disconnection of feeders have the following disadvantages:; the complexity of the manufacture of repair work and the high cost of manufacturing the distribution device.

Описываема  схема коммутации распределительных устройств  вл етс  более совершенной. Схема коммутации -нриведена на чертеже. Выключатель / устанавливаетс  только на нитаюи ем фидере.

Вслед за зтим автомат1Г-1ески откл1очг1етс  (без тока) выключатель нагрузки новрежденного фидера, иосле чего включаетс  выключатель иитающего фидера.The described switchgear switching circuit is more advanced. The switching circuit is shown in the drawing. Switch / set only on thread feeder. On outgoing feeders, as a whole, the installation costs are reduced by installing 1, switches 2 (disconnector: power supplies), which are used as for conventional switchgears: III |. so to disconnect from protections that react abnormally 1). not connected with a significant increase in current (unregulated n t. i.).

Кроме того, отличительной особенностью предлагаемой схемы  вл етс  применекис штепсельных контактов о дл  присоединеип  вькл-очател  иргтаюш.его фидера. Пpи teнeииe этих контактов значнтелы о улучшает эксплуатационные возможности, так как перерыв питани  при выводе этого выключател  в ремонт будет сведен до минимума, путем замены его резервным выключателем. Новым  вл етс  также использование выключателей нагрузки дл  отключени  от перегрузочной заншты и т. н.In addition, a distinctive feature of the proposed scheme is the use of plug-in contacts for connection of an external feeder. With these contacts, the contacts improve the operational capabilities, as the power interruption during the withdrawal of this switch for repair will be reduced to a minimum by replacing it with a backup switch. The use of switch-disconnectors for disconnecting from overload, and so on is also new.
