Mine Explosion-Proof Soft Starter Thyristor Assembly

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

4200V soft starter thyristor components,each phase consists of 4200V phase control thyristor,one set use three phase thyristor components,mainly used for medium voltage soft starter.

 

Product Features:4000v4200v-soft-starter-scr-components-small

1,This set of thyristor components using three-layer aluminum heat dissipation structure, each phase of the two devices up and down the structure of the anti-In parallel, a full three-phase assembly 6 devices are arranged in a structure, the structure Compact, lightweight, low cost, easy to install;

2，This set of SCR components can be cooled, it can be forced air cooling.

 

Thyristor Components Typical Application：

 

1，This SCR component is mainly applied 1140V and below the voltage 

level of the mine with a soft start; in three-phase system in accordance 

with the actual use to select the device on-state current average current, voltage is selected according to the use optional off-state voltage of the device; this set of optional components on-state current of 800A ~ 1600A, off-state power pressure 4200V devices;

2，This set of SCR components may also be used higher current devices, but it should be appropriate to increase the structure has been calculated size pieces.
