摘　　要：在电力系统中,常常由于某一部分或者某一电气设备的绝缘遭到损坏而引发电力事故,破坏电力系统工作的可靠性。发电厂作为电源端,电气设备的运行安全性和可靠性至关重要。在运行条件下,电气绝缘设备由于长期受湿度等因素的影响,可能形成绝缘的局部弱点和缺陷。因此,将以某燃气电厂实际运行中的绝缘故障为例,对如何提高燃气电厂设备绝缘可靠性进行探索与实践,取得了一系列成果。In power system,power accidents often occur because of the insulation damage of a part or an electrical equipment,which destroys the reliability of power system.As the power source of power plant,the operation safety and reliability of electrical equipment are very important.Under the operating conditions,the electrical insulation equipment may have some weaknesses and defects due to the long-term influence of humidity and other factors.Therefore,taking the insulation fault of a gas-fired power plant as an example,this paper explores and practices how to improve the insulation reliability of gas-fired power plant equipment,and achieves a series of results.
