Description

[根据细则26改正21.04.2018] 隔爆型电动多回转执行机构的可逆磁力启动器控制方法 技术领域
本发明涉及一种隔爆型可逆磁力启动器控制方法,尤其是涉及一种隔爆型电动多回转执行机构的可逆磁力启动器控制方法。
背景技术
随着矿井开采的现动化水平的提升,手动多回转执行机构已不能满足煤矿自动化的要求,无论是新矿建设还是老矿的改造,大、中型手动多回转执行机构正逐渐被电动的多回转执行机构所代替。
电动多回转执行机构的驱动为电力驱动,磁力启动器实现多回转执行机构的开启、闭合、停止、本地/远程控制等各种功能,并对多回转执行机构进行行程、扭矩、漏地闭锁、过载、短路、断相、欠过压等各种保护。
相关专利《煤矿井下电力驱动多回转执行机构可逆磁力启动器》,公开号为CN 103227593A以及专利《通用型电力驱动多回转执行机构可逆磁力启动器》,公开号为CN 103166538A中的附图4为程序设计流程图,但在专利说明书中没有相关控制方法的具体说明。
上述程序设计流程图中存在着诸多缺陷和问题。具体如下:
1、程序初始化后,并不一定执行“本地/远控、瞬动/自保、额定电流、电压设定、漏阻闭锁设定、密码、电流及电压倍数等参数设定”程序,而应根据试验/工作模式选择开关的所拨位置决定,参见上述相关专利附图8。
在工作模式下,并不执行上述程序设计流程图中所显示的“本地/远控、瞬动/自保、额定电流、电压设定、漏阻闭锁设定、密码、电流及电压倍数等参数设定”程序。
2、没有“试验模式”和“工作模式”的转换判定条件。
3、“漏电闭锁测验”和“漏电监控程序”所显示的“漏电故障窗口”并非程序设计流程图所显示的为同一窗口,两个“漏电故障窗口”是不一样的,参见上述相关专利附图20和附图31。
“电压测验”、“短路测验”、“过流测验”,同上也是一样的。
4、缺少“过载测验”程序,参见上述相关专利附图12、附图24和附图28。
5、“试验模式”中并没有程序设计流程图所显示的“断相测验”和“接触器触点吸合测验”程序,参见上述相关专利附图12。
6、“多回转执行机构控制主程序”上一个执行程序并不是“触点故障窗口”。
7、没有表明各个程序间运行条件、循环和返回方式,没有更详细的程序运行过程。
由于以上诸多问题,相关专利的程序设计流程图并不能够正确的运行,不能够正确的控制电力驱动多回转执行机构可逆磁力启动器。
技术问题
为解决目前隔爆型电动多回转执行机构可逆磁力启动器控制方法中存在的上述问题,本发明提供一种完整、详细的隔爆型电动多回转执行机构可逆磁力启动器的控制方法。

实施该发明的最佳实施例
本发明的最佳实施方式
本实施方式中,所采用的PLC为日本三菱公司生产的FX1N-MR60型PLC,所采用的触摸屏为日本三菱公司生产的GOT930型触摸屏。PLC所用的编程软件为GX developer 7,触摸屏所用的编程软件为GT Designer2 Version 2。
整个控制方法包括两种模式,根据试验/工作模式选择开关拨到的位置,选择进入试验及设置控制方法或者工作模式控制方法。
选择开关拨到试验模式时,首先进入“试验及设置”界面,“开启”、“闭合”按键作为上、下选择按键,多回转式执行机构“停止/确认”按键作为“确认”按键。通过循环选中性能试验、控制方式、事件查看、额定电压以及额定电流参数设定、密码设置、瞬动/自保方式设置功能按键并按确认,从而完成试验及设置控制方法的性能试验、控制方式、事件查看、额定电压以及额定电流参数设定、密码设置、瞬动/自保方式设置功能。
首先,按下“启动试验”按键,接触器触点吸合,准备进行试验。“开启”、“闭合”按键作为上、下选择按键,循环选中相应的功能按键,并按“停止/确认”按键,进行相应的试验。试验完成后,按下“返回”按键,回到上一级“试验及设置”界面。
通过输入产生故障时的故障数值,进行试验。若交流器触点断开,试验合格,并显示相应的故障试验合格界面。若试验不合格,则触摸屏停留在原界面,不能进入相应的故障试验合格界面。
通过“闭合”或“开启”按键,循环选中相应的模式,并按“停止/确认”按键加以确认。从而设定“控制方式”为“近控”或“远控”模式,“瞬动/自保”设置为“瞬动”或“ 自保”模式。设置完成后,按下“停止/确认”按键,返回“试验及设置”界面。
通过“闭合”或“开启”按键,减少或增加相应的数值,从而设定相关的电流、电压和密码值。设置完成后,按下“停止/确认”按键,返回“试验及设置”界面。
选择开关拨到工作模式时,初始化后,首先进行漏电电阻检测,若漏电电阻<额定漏电电阻,则显示“漏电故障”界面;若漏电电阻≥额定漏电电阻,漏电电阻检测合格,显示“工作模式待机”界面。若按下“开启”或“闭合”按键,可以开启或闭合执行机构,按下“停止/确认”按键,则执行机构停止运动。
在执行机构开启或闭合的时候,PLC读取相应的电压、A相电流、B相电流、C相电流数值和接触器触点通断信号,并与相应的正常值进行比较,且根据故障发生时所持续的时间,循环检测和判断是否发生欠压、过压、过流、短路、断相和接触器触点故障。若发生相应的故障,则接触器触点断开,机构停止,转入相应的故障界面。故障解除后,显示“工作模式待机”界面。上/下行程开关位置超限、开/合扭矩超限和按下“停止/确认”按键,机构停止,显示“工作模式待机”界面。
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本领域的技术人员在本发明所揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应该以权利要求书所限定的保护范围为准。
