摘 要:电力系统中的负载类型大部分属于感性负载,这导致电网功率因数较低,故在电力系统中连入电容补偿柜可以平衡感性负载,提高功率因数,从而提升设备的利用率。电容补偿柜的设计要在保证容量的前提下,尽量满足经济性的要求,而且配电室的运行安全也是重中之重。因电容补偿柜在运行过程中会产生大量的热,所以电容补偿柜的安装位置也要考虑尽可能远离安全隐患,以保证配电室变压器等重要设备的运行安全。Most of the load types in the power system are inductive loads,which will make the grid power factor lower.Therefore,by connecting a capacitor compensation cabinet in the power system,the inductive load can be balanced and the power factor can be improved to improve the utilization rate of the equipment.The design of the capacitor compensation cabinet should meet the economic requirements as much as possible while ensuring the capacity,At the same time,the operation safety of the power distribution room is also a top priority.During the operation of the capacitor compensation cabinet,a large amount of heat will be generated.Therefore,the installation location of the capacitor compensation cabinet should also be considered to be as far away as possible from the safety hazards to ensure the operation safety of transformers and other important equipment in the power distribution room.
关 键 词:感性负载 功率因数 电容补偿柜 经济性 安全隐患
