注:SRY2、SRY4型的安装孔为Ø72毫米\n2、工作电压允许误差：不大于其额定值的1.1倍，外壳应有效接地。\n3、工作环境：相对湿度不大于95%，无爆炸性和腐蚀性气体。\n4、金属管材料：10号钢。\n5、zui高工作温工：SRY2、SRY3为300℃,SRY4为100℃。\n6、SRY2型、SRY4型的工作压力小于2公斤/平方厘米。\n7、SRY3型紧固件长度为25毫米。\n三、使用维护及注意事项\n1、外形尺寸图中尺寸“B”必须全部浸入油中以免烧坏元件。被加热油应无腐蚀性。\n2、SRY3型的工作液面必须在紧固件之下，尺寸线“B”之上。\n3、熔化沥青、石蜡等固态油类时应降低电压使用，等熔化后再升至额定电压。以防止热量集中降低元件使用寿命。\n4、发现管子表面有结炭时，必须除尽后再用，以免降低效率，甚至烧坏元件。\n5、元件应存放于干燥处，若因长期放置而绝缘电阻降到低于1兆欧时，可在200℃左右的烘箱中干燥若干小时（或将元件低压通电数小时），即可恢复绝缘电阻。\n
