安修斯系列船用电罗经专用电源的设计与实现

Design and Implementation of Power Supply for An Xiu Series Gyrocompass

电罗经是海上航行的主要导航仪器之一,实践证明电源故障造成电罗经无法正常工作的现象层出不穷,通过对安修斯系列电罗经维修案例的分析,我们发现直流 24V 稳压电源不稳定等易造成死机,主要是因为实际操作过程中船舶的供电系统电源电路内含有谐波分量,所以思量怎样为电罗经提供靠得住的电流源装置,才能保证电罗经稳定工作.设计完成的专用电源,配备了故障检测报警、电压电流过载保护电路,减少开关转换的响应时间,从而确保整机性能稳定,工作可靠,性价比高.它主要适用于安修斯陀螺罗经的供电,对于其它电流不大需要稳定直流电压的通导设备同样适用,在保证航行安全的同时能为船东节省可观的费用.

Gyrocompass is one of the main navigation instruments at sea. The practice shows that lots of gyrocompasses cannot work normally because of power failures. Based on An Xiu series gyro repair cases, we found that the DC 24 v regulated power supply is not stable and easy to cause crashes, mainly because the actual operation of ship power system contains harmonic component. So how to provide reliable current source for gyro is the guarantee for the stability of gyro. A dedicated power supply is designed, which is equipped with fault detection alarm, overload protection circuit for voltage and current, and shortening the response time of the switch, to ensure that the machine performance is stable, reliable and low cost performance. It is mainly suitable for An Xiu series gyro power supply and it is also fit for other current need not stable DC voltage. It is a guarantee for the safety of navigation, meanwhile it can save considerable cost for ship owners.
