變壓器的絕緣等級，并不是絕緣強度的概念，而是允許的溫升的標準，即絕緣等級是指其所用絕緣材料的耐熱等級，分A、E、B、F、H級。絕緣的溫度等級分為A級 E級B級 F級H級。各絕緣等級具體允許溫升標準如下：最高允許溫度（℃）105 120 130 155 180  上海英施丹-變壓器

公司供應中江S11變壓器

PZH45YUG58FQF變壓器又有其做試驗而用的，稱之為試驗變壓器，分別可以分為充氣式，油浸式，干式等試驗變壓器，是發電廠、供電局及科研單位等廣大用戶的用來做交流耐壓試驗的基本試驗設備，通過了國家質量監督局的標準，用于對各種電氣產品、電器元件、絕緣材料等進行規定電壓下的絕緣強度試驗。1．防止變壓器過載運行。如果長期過載運行，會引起線圈發熱，使絕緣逐漸老化，造成匣間短路、相間短路或對地短路及油的分解。2.防止變壓器鐵芯絕緣老化損壞。鐵芯絕緣老化或夾緊螺栓套管損壞，會使鐵芯產生很大的渦流，引起鐵芯長期發熱造成絕緣老化。3.防止檢修不慎破壞絕緣。變壓器檢修吊芯時，應注意保護線圈或絕緣套管，如果發現有擦破損傷，應及時處理。主營供貨中江S11變壓器
