Mine Explosion-Proof Soft Starter Thyristor Assembly
The thyristor assemblies are specially designed for mine explosion-proof soft starter.Each phase consists of two anti-parallel phase control thyristors.We accept design and produce according to your assembly drawing.
1, used in colliery, mining and other occasions,
three-phase asynchronous motor soft starter
2, six thyristors make up three phase AC switches
3, compact, easy to install
4, can be used for natural cooling
5, specific installation size, can be
re-designed according to user requirements
Thyristor Assembly Technical Parameters:
1, flow capacity of the assembly, off-state voltage, depending on the chosen thyristors.
For example: the following figure show that each phase have two KP1000A-4200V thyristors
to make up three phase soft start components:
1, the maximum on-current (RMS) IT (RMS) = 2222A
2, repetitive peak off-state voltage VDRM≥4200V
3, repetitive peak off-state current IDRM≤70mA
4, state peak voltage VTM≤2.6V (1TM = 2400A time)
5, the gate trigger current 1GT = 40-150m
