Description

一种电梯永磁同步无齿轮曳引机的封星方法
技术领域
本发明涉及一种电梯永磁同步无齿轮曳引机的封星方法，，属于电梯控制技术领域。
背景技术
自永磁同步无齿轮曳引机在电梯上应用开始，其封星制动功能一直被作为优点宣传和应用，但是在其提供安全保护的同时，也增加了了电梯事故的风险。封星技术，即永磁同步无齿轮曳引机将三相绕组引出线按星型连接。此时曳引机作为三相交流永磁发电机，电梯机械平衡***的不平衡力矩带动曳引轮运转，发电机吸收机械能转化为电能，通过封星所形成的闭合回路将电能转化为电磁转矩与机械转矩相抗衡，使永磁同步无齿轮曳引机的曳引轮转速降低。封星技术可用在紧急救援时，放闸，使电梯轿厢利用自重自行运动时可以稳定在一个匀速状态；封星技术通常也可用于配合制动设备进行制动（如公布号为CN102398813 A的中国专利申请），但是由于封星后闭合回路上的电流大小与曳引机的转速有关，当电梯轿厢运行速度过快，也即永磁同步无齿轮曳引机的转速过高，会导致这个闭合回路过载，从而造成封星接触器或线圈烧坏，仅仅如公布号为CN 102398813 A的中国专利申请所记载的增大接触器容量，并不能从根本上解决过载的问题。
发明内容
本发明的目的在于，提供一种电梯永磁同步无齿轮曳引机的封星方法。本发明可以在永磁同步无齿轮曳引机封星时，不会出现过载现象，同时也可使封星制动时。
本发明的技术方案：一种电梯永磁同步无齿轮曳引机的封星方法，它是在断开变频器输出端的主接触器KM1后，延时闭合永磁同步无齿轮曳引机进线端的封星接触器KM2，其特征在于：在永磁同步无齿轮曳引机的每条进线上均串联有常闭触点KM3, 常闭触点KM3上并联有电阻R,主接触器KM1、封星接触器KM2和常闭触点KM3的动作顺序依次为，先断开常闭触点KM3，再断开主接触器KM1，然后闭合封星接触器KM2，待永磁同步无齿轮曳引机转速下降到一定数值时，再闭合常闭触点KM3。在先断开常闭触点KM3，再断开主接触器KM1，然后闭合封星接触器KM2后，永磁同步无齿轮曳引机成为一个发电机，且在一个带负载（电阻R）的回路。当转速过高时，由于电阻R的作用，回路中电流不会不高，因此不会烧坏接触器或绕组。且由于电流相对没有电阻R时要低，所以开始产生的电磁力矩也较小，因而不会使电机造成突然的速度变化，减缓了对电梯内的乘客的冲击。有当速度减慢后，闭合常闭触点KM3，即短路电阻R，使电流升高，提高电磁力矩。因而，本发明实际上将封星后的电梯制动分隔成2个步骤进行缓冲，防止器件烧坏的同时，也提高了制动的平稳性。
上述的电梯永磁同步无齿轮曳引机的封星方法中，为了进一步提高制动的平稳性，所述永磁同步无齿轮曳引机的每条进线上均串联有多个常闭触点KM3，每个常闭触点KM3上并联有电阻R，常闭触点KM3重新闭合的阶段中，各个常闭触点KM3随着永磁同步无齿轮曳引机转速的降低，逐个闭合，即回路中的电阻值逐渐减小。
前述的电梯永磁同步无齿轮曳引机的封星方法中，所述主接触器KM1、封星接触器KM2和常闭触点KM3与接触控制器相连，其动作时序由接触控制器控制；且接触控制器还与永磁同步无齿轮曳引机上的编码器相连，用于采集永磁同步无齿轮曳引机转速。
与现有技术相比，本发明在对永磁同步无齿轮曳引机进行封星时，使封星后的回路先带负载运行，以避免电流过大造成器件损坏。在永磁同步无齿轮曳引机因为封星处理而转速下降到一定程度时，短路负载，进行第二阶段的制动，从而使永磁同步无齿轮曳引机处在一个较为平稳的减速状态。本发明将制动过程分为微观的多个阶段，使封星回路持续提供一个平稳的制动力，从而缓冲了对电梯乘客的冲击，提高电梯安全性能的同时，也提高了乘客的舒适度。
附图说明
图1是本发明实施例封星电路示意图。
具体实施方式
下面结合附图和实施例对本发明作进一步的说明，但并不作为对本发明限制的依据。
实施例。一种电梯永磁同步无齿轮曳引机的封星方法，它是在断开变频器输出端的主接触器KM1后，延时闭合永磁同步无齿轮曳引机进线端的封星接触器KM2，在永磁同步无齿轮曳引机的每条进线上均串联有常闭触点KM3, 常闭触点KM3上并联有电阻R, 主接触器KM1、封星接触器KM2和常闭触点KM3的动作顺序依次为，先断开常闭触点KM3，再断开主接触器KM1，然后闭合封星接触器KM2，待永磁同步无齿轮曳引机转速下降到一定数值时（由于不同曳引机的功率不同，电梯内机械平衡***的不平衡力矩不同，可采用实测的方式确定，转速与电流的关系曲线，再确定电阻R），再闭合常闭触点KM3。
所述永磁同步无齿轮曳引机的每条进线上均串联有多个常闭触点KM3，每个常闭触点KM3上并联有电阻R，常闭触点KM3重新闭合的阶段中，各个常闭触点KM3随着永磁同步无齿轮曳引机转速的降低，逐个闭合。如图1所示的每条进线上均串联有个2个常闭触点KM3的情况。
