Direct current charger ripple monitoring device

一种直流充电机纹波监测装置

Abstract

The invention provides a direct current charger ripple monitoring device. The direct current charger ripple monitoring device comprises a direct current charger, a direct current ripple sensor, and an alarming module. The direct current ripple sensor is connected with the output end of the direct current charger, and the alarming module is connected with the direct current ripple sensor. The direct current charger ripple monitoring device is advantageous in that the output end of the direct current charger is provided with the direct current ripple sensor, and the ripple coefficient of the output end is measured in a real-time manner; when the ripple coefficient exceeds a limit value required by a regulation, a signal is sent to prompt a worker to carry out inspection processing; and the inspection can be carried out without waiting for the regular inspection of the direct current system, and therefore performance degradation and shortening of service lifetime of a storage battery caused by the overlarge ripple coefficient of the charger are prevented.
本发明实施例提供的一种直流充电机纹波监测装置,包括:直流充电机、直流纹波传感器、报警模块;所述直流纹波传感器连接所述直流充电机的输出端;所述报警模块连接所述直流纹波传感器。本发明实施例通过在直流充电机的输出端设置直流纹波传感器,实时测量输出端的纹波系数,当纹波系数超过规程要求的限值时,即发出信号,提醒工作人员进行检查处理,无需等到直流系统定检,避免了由于充电机纹波系数过大,造成的蓄电池性能下降和寿命缩短。
