Description

用于玻璃厂的主传动控制方法 技术领域
本发明涉及机械电气控制技术领域，尤其涉及一种用于玻璃厂的主传动控制。
背景技术
目前,大部分玻璃厂主传动控制是利用计算机控制，主要是通过计算机模拟量输出4～20mA信号，控制变频器频率来达到控制主传动电机的转速,这种控制方法容易造成4～20mA信号受干扰,造成主传动电机的转速不准。随着玻璃品种向超厚和超薄两个方向的发展，对主传动的控制精度要求也越来越高，这种控制方法已不能完全满足较高档次玻璃品种对主传动控制精度的要求。
玻璃厂主传动采用两台电机,一台工作,一台热备,目前两台主传动电机控制回路都装在一个控制箱内，当其中一台故障维修时，容易造成误操作或互相干扰现象,造成人为生产事故,同时两台主传动电机分别由单独的市电电源或UPS电源供电，当市电电源或UPS电源其中任一电源故障时，就有一台电机停止工作，不能满足一台工作，一台热备的要求。
针对以上的缺点和要求，设计出了一种新的实用的主传动控制方法，既能满足工艺精度要求又简单安全可靠。
发明内容
本发明旨在填补现有主传动控制技术的空白，提供一种用于玻璃厂用的主传动控制方法。
为了达成上述目的，提供了一种用于玻璃厂的主传动控制方法，包括如下步骤：(a)在电机的电源回路上设置第一断路器和第二断路器，其一端分别连接至两台主传动电机；(b)使得所述第一断路器与市电电源连接，所述第 二断路器与UPS电源连接；并且(c)使得所述第一断路器和第二断路器通过机械联锁机构联锁，以使得正常工作时只有其中任意一个断路器可以合闸。
一些实施例中，各所述主传动电机上设有变频器，利用在变频器数字输入端口上设置加/减速按钮，通过操作加/减速按钮来改变变频器的频率实现主传动电机速度的调整。
一些实施例中，利用所述变频器脉冲输出信号至脉冲数显表。
一些实施例中，将变频器故障输出继电器串入主接触器分闸回路。
一些实施例中，将两台电机控制回路分别设置在单独的控制箱内。
根据本发明的一种用于玻璃厂的主传动控制方法，克服了信号受干扰造成的主传动电机的转速不准的问题。满足了当市电电源或UPS电源其中任一电源故障时，两台电机均不能停止工作的要求；同时将两台主传动控制系统分别设置独立的控制箱，避免了任一台故障或维修时人为事故的发生。
以下结合附图，通过示例说明本发明主旨的描述，以清楚本发明的其他方面和优点。

下文详细说明根据本发明实施例的一种用于玻璃厂的主传动控制方法.
首先，在电机的电源回路上设置第一断路器和第二断路器，其一端分别连接至两台主传动电机。其次，使得所述第一断路器与市电电源连接，所述第二断路器与UPS电源连接。最后，使得所述第一断路器和第二断路器通过机械联锁机构联锁，以使得正常工作时只有其中任意一个断路器可以合闸。

为了满足当市电电源或UPS电源其中任一电源故障时，两台电机均不能停止工作的要求，在每台电机电源回路上装设两台断路器，即给每台电机两路电源，一路市电电源，另一路为UPS电源,两台断路器通过机械联锁机构联锁，正常工作时只有其中任意一个断路器可以合闸，从而保证了任一电源故障时，两台主传动电机都能正常工作。
为了满足速度调整精度的要求，在主传动每台电机上设有一台变频器，利用在变频器数字输入端口上设置加/减速按钮，通过操作加/减速按钮来改变变频器的频率实现主传动电机速度的调整。

为了保证任意一台主传动电机故障或维修时,不至于造成误操作或互相干扰现象,将两台电机控制回路分别设置在单独的控制箱内，如图3所示。
实现该控制方法通过以下步骤：(以下为1#主传动，2#主传动与1#相同)
(1)检查主传动每台电机旋转方向，使每台电机旋转方向正确，满足工艺要求；检查控制柜内两路电源相序一致性,保证两路电源相序相同。
