节约电能是降低砖瓦产品成本,增加经济效益的重要途径之一.对于电力无功功率补偿,一般采用在高压倒或低压侧安装电容器进行集中补偿,来提高电网的功率因数,这种集中补偿能使电力系统35%的无功损耗得到适当的补偿.但用户末端使用的电动机以及输电线路65%的无功损耗,没有能从集中补偿中得到解决.无功功率就地补偿器就是为解决这部分无功损耗的补偿装置.砖瓦生产中,由于负荷冲击、重载、频繁启动,使企业的自然供电功率因数较低,就我市砖瓦企业的统计数为0.60～0.85.所以有必要安装就地无功功率补偿器进行补偿,提高电动机的功率因数,以达到节约电能的目的.
Saving electric energy is one of the important ways to reduce the cost of brick and tile products and increase economic efficiency. For the reactive power compensation of electric power, it is generally adopted to install capacitors on high-voltage inverted or low-voltage side for centralized compensation to improve the power factor of the power grid. Such centralized compensation 35% of the power system can be compensated for reactive losses. However, the motor used by the end user and the 65% reactive power loss of the transmission line cannot be resolved from the centralized compensation. The reactive power on-site compensator is to solve the problem. This part of the reactive power loss compensation device. In the production of bricks, due to load impact, heavy load, frequent start, so that the company’s natural power factor is low, the city’s brick and tile business statistics is 0.60 ~ 0.85. So there It is necessary to install the local reactive power compensator to compensate and increase the power factor of the motor so as to save energy.
