Analysis of the causes and preventive measures of equipment heating in power substation operation
电力变电站运行中设备发热的原因及预防措施浅析

摘要

现阶段，随着社会用电需求的进一步扩大，变电站设备体系的规模和复杂程度都在不断提升，给设备维护与管理工作带来了极大的难题，设备故障或异常问题时有发生，严重影响变电站的供电稳定性、可靠性。设备发热问题就是其中一个重要问题，发热问题的存在使得相关设备中的电子元件可能在高温下损坏而无法正常工作，过多的热量也会直接造成零部件的损坏，如接线端子变形、绝缘材料老化等，给变电站的安全稳定运行带来极大的隐患。因此，出于保证设备正常运行和稳定需求方面的考虑，仍然有必要对变电站运行中设备发热的原因进行明确，这将有助于进一步采取有效的防控措施，保证变电站设备运行的可靠性。

Abstract

At present, with the further expansion of social demand for electricity, the scale and complexity of substation equipment system are constantly improving, which brings great problems for equipment maintenance and management. Equipment failure or abnormal problems occur from time to time, which seriously affects the stability and reliability of power supply of substation. Equipment heating problem is one of the important problems, the existence of the heating problem makes the electronic components in the relevant equipment may be damaged at high temperature and can not work normally, too much heat will also directly cause damage to the parts, such as terminal deformation, insulation material aging, etc., to the safe and stable operation of the substation brings great risks. Therefore, in order to ensure the normal operation and stable demand of the equipment, it is still necessary to clarify the causes of equipment heating during the operation of the substation, which will help to further take effective prevention and control measures to ensure the reliability of the operation of the substation equipment.
