Abstract

本实用新型涉及一种电力机车用永磁机构断路器控制信号转换装置，用于将电力机车原用的压缩空气断路器改为永磁机构操动主断路器、两者之间控制信号的转换。它包括一信号输入端口和一信号输出端口，在所述的信号输入端口和信号输出端口之间，对称设置有两个光电耦合器——上光电耦合器和下光电耦合器。光电耦合器的前端有二极管发光元件，后端有光敏元件。本实用新型通过光电耦合器能实现电信号耦合。电力机车的分合闸信号，经过光电耦合器耦合，转换为永磁机构断路器能够识别的分合闸控制信号。

Description

电力机车用永磁机构断路器控制信号转换装置
技术领域
本实用新型涉及控制线号转换装置，属于国际专利分类H03K技术领域。 
背景技术
原先的电力机车，使用压缩空气断路器，其控制信号以机车电源为准，该电源波动较大，对于先进的由永磁机构操动的断路器来说，其电源要求稳定。原有的控制信号和永磁机构控制器所需要的控制信号，无法直接相连。 
发明内容
本实用新型的目的，在于提供一种电力机车用永磁机构断路器控制信号转换装置，以实现两者控制信号的转换。 
本实用新型的技术方案如下。 
一种电力机车用永磁机构断路器控制信号转换装置，用于将电力机车原用的压缩空气断路器改为永磁机构操动主断路器、两者之间控制信号的转换，它包括一信号输入端口和一信号输出端口，在所述的信号输入端口和信号输出端口之间，对称设置有两个光电耦合器——上光电耦合器和下光电耦合器。 
所述的光电耦合器前端有二极管发光元件，后端有光敏元件。 
本实用新型解决了原有的电力机车，对主断路器的控制信号，经过转换能适应新型永磁机构断路器的控制需求。这样，电力机车原有的控制电路不用改变，机车司机的控制操作也不变，即可适应新的要求。 
附图说明
图1为本实用新型电力机车用永磁机构断路器控制信号转换装置的结构示意图。 
图2为光电耦合器的示意图。 
图3为原理说明图。 
图中：1、输入端口，2、光电耦合器，3、光电耦合器，4、输出端口。 
具体实施方式
参见图1，电力机车用永磁机构断路器控制信号转换装置，用于将电力机车原用的压缩空气断路器改为永磁机构操动主断路器、两者之间控制信号的转换，它包括一信号输入端口1和一信号输出端口4，在所述的信号输入端口1和信号输出端口4之间，对称设置有两个光电耦合器——上光电耦合器2和下光电耦合器3。 
参见图2，光电耦合器前端有二极管发光元件，后端有光敏元件。 
参见图3，电力机车控制信号转换装置，包括有与电力机车控制线路相连的信号转换模块。所述信号转换模块包括有：与电力机车控制信号线相连的信号转换单元；该信号转换单元内部的信号转换用光电耦合器能实现电信号耦合。电力机车的分合闸信号，经过光电耦合器耦合，将该分合闸型号转换为永磁机构断路器能够识别的分合闸控制信号。电信号使光电耦合器前端的的发光元件发光，光电耦合器的后端光敏元件接受到前端发出的光信号则将后端电路导通，信号被传递到后级电路。 
通过光电耦合器电路，将原有的电力机车控制信号转换为永磁机构断路器需要的信号，解决了电力机车对永磁操动机构断路器的控制问题。 
以上所述，为本实用新型的优选实施方式。应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为对本专利的保护范围。
