【導(dǎo)讀】為了使得導(dǎo)線(xiàn)相互隔離并且不接觸到其他的物體，必須采取絕緣措施。想的條件下，絕緣應(yīng)做到完全不導(dǎo)電，那樣電流才能會(huì)完全束縛在計(jì)劃的導(dǎo)體內(nèi)。阻率的材料看待。在許多情況下，由于絕緣材料的導(dǎo)電性造成的漏電流很小，以。致于可以忽略不計(jì)。在一些情況下，采用非常敏感的儀器測(cè)量的漏電流可以用來(lái)。確定某種絕緣措施是否合適。材料被強(qiáng)烈地導(dǎo)致其迅速損壞。在電力系統(tǒng)中有相當(dāng)比例的設(shè)備損壞是由于絕緣。絕緣設(shè)計(jì)人員面臨的問(wèn)題包括選擇合適的材料、合適的形狀和尺寸，以及控制破壞性因素等。在居民小區(qū)，分支線(xiàn)和電線(xiàn)中的導(dǎo)體可以采用橡膠或各種塑料材料絕緣。這些材料可以承受必要的彎曲，但其電器應(yīng)力較低。用幾厘米厚的絕緣處理。這些絕緣材料必做成長(zhǎng)形的，并且足夠柔軟，以便于將。其穿進(jìn)小口徑的管道。發(fā)電機(jī)和電動(dòng)機(jī)的繞組可以采用絕緣帶絕緣。電力變壓器的繞組的絕緣通常采用油浸紙帶和壓制紙板。和鐵芯損耗引起的熱量。在支撐件之間是采用空氣絕緣的。
【正文】 are of fiber glass inpreating with insulating insulation must be capable of withstanding quite high operating temperatures， extreme mechanical forces， and vibration. The insulation on powertransformer windings is monly paper tape and pressboard operated under oil saturates the paper， greatly increasing its insulation strength， and by circulating through ducts， serves as an agent for carrying a way the heat generated due to RI2 losses and core losses in the shape and arrangement of conducting metal parts is of particular concern in transformer design. Overhead lines are supported on porcelain the supports air serves as is chosen because of its resistance to deterioration when exposed to the weather， its high dielectric strength， and its ability to wash clean in rain.
