Cautions and Warnings General警告和一般提醒
•Thyristor power units TU series may only be used for the purpose they have been designed for.
TU系列晶闸管功率单元仅可用于设计。
•Thyristor power units TU series may only be used in combination with appropriate pre-switched grid separator device.
TU系列晶闸管功率单元只能与适当的预切换电网分离器装置结合使用。
•Thyristor power units have to be projected in such a way that in case of any failure no uncontrolled high current and voltages may occur.
晶闸管功率单元必须考虑到在任何故障的情况下不会出现不受控制的高电流和电压这样的情况。
•The devices in operation have to be protected against moisture and dust, sufficient cooling has to be assured.
操作中的设备必须防止潮湿和灰尘,必须确保充分的冷却。
 
Attention注意
Due to the switching principle of the thyristor power unit the power capacitors are permanently loaded to the peak value of the grid voltage (DC voltage) even when switched off.
由于晶闸管功率单元的投切原理,即使在关断时,电力电容器也长期地加载在电网电压(直流电压)的峰值。
Therefore following rules have to be obeyed in any case
因此,在任何情况下必须遵守以下规则:
•For standard PFC-systems (without reactors) power capacitors of 440 V nominal voltage have to be used; for detuned systems PFC capacitors of 480 V nominal voltage have to be used.
对于标准PFC系统(无电抗器),必须使用440 V标称电压的电力电容器; 对于失谐系统,必须使用480 V额定电压的PFC电容器。
•Due to the high voltage (2 x peak value of nominal voltage) that occurs, the discharge resistors of the power capacitors have to be replaced by special types (1 x accessory EW22).
由于发生高电压(2 x标称电压峰值),电力电容器的放电电阻必须替换为特殊类型(1 x附件EW22)。
•In dynamic systems with TSM power units no fast discharge reactors may be used (reactor = DC wise short circuit).
在具有TU功率单元的动态系统中,不能使用快速放电反应器(反应器=直流短路)。
•For standard PFC-systems 2 current limiting reactors are mandatory per thyristor power unit (2 x BD050 or 2 x BD100).
对于标准PFC系统,每个晶闸管功率单元必须要2个限流电抗器(2个BD050或2个BD100)。
•Thyristor power unit in general have to be protected by superfast electronic fuses. Principles for dimensioning have to be considered. Fuses in the system have to be marked.
晶闸管功率单元通常必须由超快速电子保险丝保护。 必须考虑尺寸标注的原则。 系统中的保险丝必须标记。
•Due to the special switching, the PFC capacitors are fully loaded even when the particular step has been switched off. Protection against contact has to be guaranteed. Warning signals in the systems are required.
由于投切的特殊,PFC电容器即使通过特定的步骤已关闭时也是完全加载的。 必须保证防止接触。在系统报警信号是必需的。
•Even in switched off state no electrical isolation is achieved for electronic switches. Therefore parts of the systems may not be touched after switching off the complete system before the capacitors have been completely discharged.
即使在关闭状态下没有电气隔离是电子开关来实现的。因此,在整个系统关闭之后电容器完全放电之前系统的部分可能不能触摸。
 
FAILURE TO FOLLOW CAUTIONS MAY RESULT, WORST CASE, IN PREMATURE FAILURES OR PHYSICAL INJURY.
未能遵守注意事项可能导致,最严重的情况,造成故障或身体受伤。
