ABB UFC765AE102 3BHE003604R0102连接的电流容量值
转子接触器不得由任何PLC或类似装置进行额外控制。重要的是
ASTAT的DO直接控制转子接触器，因为转子控制是真实的集成部分
时间运动控制，分辨率为3ms。
选择和应用建议：
1） 将接触器连接到星形，而不是Δ。推荐表基于星形连接。
2） 所有接触器都被认为是最终短路转子接触器。这补偿了由于主晶闸管控制引起的短时间低磁化和谐波对触点的额外加热。
3） 接触器的闭合操作是利用转子电流进行的。
典型值：转子额定电流的1,0-1,5倍。
4） 接触器的断开操作是在零转子电流的情况下进行的。
5） 安装温度为55摄氏度。将低于70摄氏度的值降低。
6） 这些装置很多时候是在带有导电灰尘的钢结构起重机的面板上制造的。所有组件
在开放式面板中，必须符合EN 60664，污染等级4。我们建议保留接触器
通过将其安装在尺寸合理的封闭隔间/盒子中进行清洁，以避免因其自身损失而发热，
或者使用坚固的接触器。
7） 为了获得良好的控制财产，需要一个断开时间短、闭合时间短的接触器。考虑涌入线圈电流对控制变压器的大小。
8） 触点的寿命（电寿命）计算为与
接触器机械系统（机械耐久性）。
9） 对于Δ连接的电流容量值，将表中的数字乘以1,5或1,73，具体取决于
制造商建议。但是，Δ-连接增加了电压应力（寿命更短），面板接线工作量更大，电线选择和拧紧扭矩的质量控制措施更严格。
10） 建议将接触器线圈直接连接到过程I/O板的DO继电器，仅用于
引入电流小于等于2A的交流线圈接触器。对于较大的交流接触器和所有直流接触器，应使用pi批继电器。
使用ABB接触器，A75是最大尺寸的，带有110 V AC线圈和EH 145（旧系列）/A 110（新
范围）最大尺寸，其中230V AC线圈仍然不需要导频继电器。
11） 以下时间适用于交流线圈接触器。时间可能与目录值略有不同，以匹配
ASTAT的实时控制系统。
12） 列出的ABB和Schneider的接触器是用传统线圈制成的，而
西门子公司采用电子磁铁系统。
The rotor contactors should never be additionally controlled by any PLC or similar. It is important that the
DOs of the ASTAT directly control the rotor contactors, as the rotor control is an integrated part of the real
time motion control with 3 ms resolution.
Selection and application recommendations:
1) Connect the contactors in Star, not in Δ. The Recommendation tables are based on Star connection.
2) All contactors are thermally considered as final short circuit rotor contactors. This compensates for the additional heat up of the contacts from short time low magnetisation and harmonics due to the primary thyristor control.
3) The closing operation of the contactors is made with rotor current.
Typical value: 1,0 - 1,5 times rated rotor current.
4) The opening operation of the contactors is made with zero rotor current.
5) Installation temperature is 55 degree C. Reduce the values below for 70 degree C.
6) The installations are many times made in panels in steel work cranes with conductive dust. All components
in open panels must correspond to EN 60664, Pollution degree 4. We recommend keeping the contactors
clean by installing these in a closed cubicle / box of reasonable size to avoid heat-up by their own losses,
or to use robust contactors.
7) For good control properties a contactor with short opening time is needed, and short closing time is desired. Consider that the inrush coil current sizes the control transformer.
8) The lifetime of the contacts (electrical endurance) is calculated to be the same as the calculated lifetime of
the contactors mechanical system (mechanical endurance).
9) For Δ-connected current capacity values, multiply the figures in the tables by 1,5 or 1,73, depending on the
manufacturers recommendations. But, Δ-connection increases voltage stress (shorter life), the panelwiring job is larger and the quality control measures of wire selection and tightening torque are stricter.
10) It is recommended to connect the contactor coil directly to the DO relay of the process I/O-board only for
AC-coil-contactors with a pull-in current of 2 A or less. For larger AC-contactors and all DC-contactors a pilot relay shall be used.
Using ABB contactors, A75 is the largest size with 110 V AC coil and EH 145 (old range) / A 110 (new
range) the largest size with 230 V AC coils still not needing a pilot relay.
11) The times below are for AC-coil-contactors. The times might differ slightly from catalogues values to match
the real time control system of ASTAT.
12) The listed contactors from ABB and Schneider are made with conventional coils, while the contactors from
Siemens are made with electronic magnet system.
