The device is suitable for grids with a solidly grounded neutral with a voltage of three-phase alternating current 380/220 V, having a frequency of 50-60 Hz. Also, ASUs are used as protection for electrical equipment and power lines in cases of operational disconnections and switching on of the electrical network, overloads and short circuits. The devices are used in switchboards and other premises of various objects: residential, administrative, industrial. TERMS OF USE According to GOST 15150, the height above sea level should not be more than 2000 m. When operating the ASU at an altitude of more than 1000 m above sea level, the rated currents must be reduced by 10%. According to GOST 15150, the device is capable of operating at temperatures ranging from +1 to + 35 ºС. According to GOST 15150, the atmosphere must be type II - industrial. With regard to the environment, there are requirements for the absence of the danger of explosion and the elimination of the content of corrosive gases and concentrations of vapors that can destroy insulation and metals, as well as conductive dust. For ASP operation, the position in space must be vertical with a permissible deviation not exceeding 5º. The nominal operating mode is continuous. CONSTRUCTION OF ASU The input-distribution device is a set of electrical structures and devices, which are assembled in unified frame panels of one-way service. ASU boards can be single and multi-panel with IP31-IP54 degree of protection. The panels of the device differ depending on the purpose: Introductory - for accounting and input of indicators of electrical energy. They are equipped with breakers, circuit breakers, current transformers and electricity meters. Distribution - for the distribution of electricity to individual consumers. They are equipped with automatic switches. Introductory distribution - combine the functions of panels of the first and second type. As a rule, the input distribution device is assembled from input typical panels and distribution panels. The design of the ASU provides for the possibility of product execution in accordance with the place of the proposed installation, inside or outside the electrical room. The cabinet-type device is delivered with the equipment already installed inside: this includes both internal electrical connections and wires. Electrical devices ASU can be mounted on a frame, on a door or in a cabinet. In the panels of the device there are places for the installation of fuses, circuit breakers, electricity meters, lighting control units, capacitors, ammeters and voltmeters, test boxes. An indication of key parameters of the electrical network can be displayed on the door. The ASU have an electrically protective PE bus connected to the case and a zero working bus N isolated from the case. Ввод и вывод кабелей и проводов в ВРУ осуществляется снизу: это стандартный вариант исполнения. Но если устройство изготавливается на заказ, могут вноситься изменения и предлагаться оптимальные по удобству варианты. Также комплектация ВРУ может дополняться блоком АВР, а на лицевой панели возможен монтаж измерительных приборов и светосигнальной аппаратуры. ПРИМЕНЯЕМАЯ АППАРАТУРА Вводно-распределительное устройство предполагает наличие аппаратов ввода, которые выполняются в виде переключателей ВД и ПЦ, выключателей-разъединителей ВР 32. В качестве аппаратов распределения ВРУ применяются предохранители типа ППН, автоматические выключатели до 100 А модульного исполнения, силовые автоматические выключатели от 100 А до 630 А. По заказу устройство может выполняться с аппаратами фирм «Шнейдер-Электрик», АББ и других производителей.
