101Spot welding — is a type of resistance welding used to weld various sheet metal products. Typically the sheets are in the 0.5 3.0 mm thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to… …
102Single-wire earth return — (SWER) or single wire ground return is a single wire transmission line for supplying single phase electrical power from an electrical grid to remote areas at low cost. It is principally used for rural electrification, but also finds use for… …
103Copper loss — is the term often given to heat produced by electrical currents in the conductors of transformer windings, or other electrical devices. Copper losses are an undesirable transfer of energy, as are core losses, which result from induced currents in …
104Push–pull converter — A push–pull converter is a type of DC to DC converter that uses a transformer to change the voltage of a DC power supply. The transformer s ratio is arbitrary but fixed; however, in many circuit implementations the duty cycle of the switching… …
105Reflectional receiver — A Reflectional radio receiver (also called a reflex radio) is a radio receiver design in which the same amplifier is used for both the high frequency radio (RF) and low frequency sound (AF) signals. The radio signal from the output of the… …
106Disasters — ▪ 2009 Introduction Aviation January 23, Poland. A Spanish built CASA transport plane carrying members of the Polish air force home from a conference on flight safety in Warsaw crashes near the town of Miroslawiec; all 20 aboard are killed …
107безопасный разделительный трансформатор — защитный разделительный трансформатор Трансформатор, у которого первичная обмотка отделена электрически от вторичной обмотки изоляцией, по меньшей мере эквивалентной двойной или усиленной изоляции, и который предназначен для питания цепей… …
108вторичная обмотка трансформатора тока — Обмотка, по которой протекает трансформированный (вторичный) ток. [ГОСТ 18685 73] EN secondary winding (of a current transformer) a winding which supplies the current circuits of measuring instruments, meters, protective or control devices [IEV… …
109вторичный ток трансформатора тока — Ток, протекающий по вторичной обмотке трансформатора тока. [ГОСТ 18685 73] вторичный ток (трансформатора тока) Ток, протекающий по вторичной обмотке трансформатора тока при прохождении тока по первичной обмотке [СТ МЭК 50(321) 86] EN secondary… …
110номинальная мощность Sном — Полная мощность, определяющая вместе с номинальным напряжением номинальный ток обмотки. Примечания 1 В двухобмоточном трансформаторе обе обмотки имеют одинаковую номинальную мощность, равную номинальной мощности трансформатора. 2 Для… …
