背景技术Background technique
变电站，改变电压的场所。为了把发电厂发出来的电能输送到较远的地方，必须把电压升高，变为高压电，到用户附近再按需要把电压降低，这种升降电压的工作靠变电站来完成。变电站的主要设备是开关和变压器。变电站是很重要的一个场所，因此需要人对其值守，并对变电站内的设备进行巡检。因为变电站是个特殊的场所，当某一部分设备出现故障时，可能危及巡检人的人身安全。因此，我们有必要设计一款不需要值班员或巡检员对变电站进行值守，就能知道变电站运行情况，确保及时发现及时处理，将安全隐患降到最低。Substation, a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. The main equipment of substations are switches and transformers. The substation is a very important place, so people need to be on duty and inspect the equipment in the substation. Because the substation is a special place, when a certain part of the equipment fails, it may endanger the personal safety of the inspectors. Therefore, it is necessary for us to design a substation that does not require watchmen or inspectors to be on duty to know the operation of the substation, ensure timely detection and timely processing, and minimize safety hazards.
