■Used in coal mine, mining and other occasions of three-phase asynchronous motor soft start systems
■Three AC switch is composed of six thyristors
■Compact structure and easy to install
■Can be used for natural cooling
■Specific installation size can also be designed according to user requirements |
Main technical parameters such as current and voltage, is determined by the selection of the thyristor
Such as shown below each phase consists of two KP1000A/4200V thyristor to be a three-phase soft start assemblies
1、 Max on state current(RMS) |
IT(RMS)=2222A |
2、Repetitive peak off-state voltage |
VDRM≥4200V |
3、Repetitive peak off-state current |
1DRM≤70mA |
4、Peak on-state voltage |
VTM≤2.6V(1TM=2400A时) |
5、Gate trigger current |
1GT=40-150mA(两只晶闸管1GT之差≤20mA) |
6、Gate trigger voltate |
VGT=1.0-2.6V |
