2222A compact Soft Starter Thyristor Assembly used in colliery

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.

Features:

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 = 40-150mA (two thyristors 1GT the difference ≤20mA)

6, gate trigger voltage VGT = 1.0-2.6V
