摘　　要：广播电视信号发射是一个将电能转换为电磁能的工作过程,能量转换效率相对较低,电能消耗较大。在当今发射机能效已达到瓶颈状态的情况下,可以利用太阳能辅助供电的方式来降低日常电能的损耗。介绍为发射机添加太阳能光伏辅助供电的方法,即在设备运行过程中采取直接供电和关键点供电的方式,使设备自动优先使用光伏发出的电。当阳光不足时,市电自动增加电流流量,从而达到省电的效果。Radio and television signal transmission is a working process to convert electrical energy into electromagnetic energy,the form of energy conversion efficiency is relatively low,is a large power consumption of the working process.In the case that the energy efficiency technology of today’s transmitter has reached the bottleneck state,we can use the way of solar auxiliary power supply to reduce the loss of daily energy.This paper introduces the method of adding a solar photovoltaic auxiliary power supply to the transmitter.During the operation of the equipment,the way of direct power supply and key point power supply is adopted,and the equipment automatically uses the electricity emitted by photovoltaic.When the sunlight is insufficient,the mains automatically increases the current flow,so as to achieve the effect of power saving.
