Product Description

I Overview

TCS series of voltage-reduced compensation solid soft starting devices are applicable to   large or medium-sized high voltage squirrel-cage AC asynchronous motor or asynchronously started high-voltage synchronous electric motor for the purpose of motor soft starting.The device can achieve small and invariable current and large torque with gradual increase characteristic of the soft starting when starting the electric machine, and the influence on starting grid is very small, and no electromagnetic interference.Its starting performance is superior to the frequency converter for simple structure, exempting from maintenance and no harmonics and it is also an ideal substitute for all kinds of voltage-reduced starting products.
The device uses two patented technologies, technical level of domestic leading an international initiative.
Patent:ZL 2006 2 0098882.0;ZL 2006 2 0095622.8.
The device can be applied to the soft starting of the 6,10kv large capacity motor below 50000kw.

II Principle and equipment

1.The overall structure and working principle
The main circuit as shown in Figure 2-1:
Tcs Series Voltage Reduce and Compensation Solid Soft Starter
                                                            Figure 2-1 TCS main circuit
The device include voltage-controlled device and reactive power control device, also it   needs start cabinet, running cabinet and other relative switch cabinet.The device through the start cabinet is connected with the 10kV bus.When start high-voltage power through the device to provide starting power for the motor.Then close the running cabinet to provide running power for the motor.
Because large motor in the starting process will consume a large amount of reactive power, causing power grid voltage fluctuations.In order to reduce motor starting influence of the grid voltage, the device provides a reactive power generator which is connected with the motor in parallelproviding for Motor Starting some of the needs of reactive power.
In order to further reduce the bus current I1, the device connect the reactive power control devices and motor through a voltage transformer to bus, by reducing the terminal voltage to further reduce the current.The output current of the transformer is the difference between motor current ID and reactive power current IC, the ratio between first and second voltage of the transformer is 1:K,k<1)..

Therefore, by adjusting the voltage ratio of the transformer and reactive power current the starting current which flows from bus bar can be limited within a certain range.
2.Device components and their function
This device consists of voltage controlled device and reactive power control device, it also needs start cabinet, running cabinet and other supporting switch cabinets.Voltage controlled device includes the voltage transformer and voltage control cabinet;Reactive power control device includes reactive power generator and reactive power control cabinet.
Tcs Series Voltage Reduce and Compensation Solid Soft Starter

The role of voltage transformer is to reduce the motor terminal voltage to an appropriate value of starting.The voltage transformer input from the bus voltage, taking into account the power grid and load fluctuations, the voltage transformer is set to three switch positions.
There are two functions of the voltage control cabinet:First, to regulate the balance of secondary voltage and weaken the neutral point of the voltage drift;Second, to reduce the switch surge.
The role of reactive power generator is to provide reactive power to motor, reduce the reactive current of absorption from the grid, thereby to reduce the impact on the power grid.As figure2-2 shown:
Tcs Series Voltage Reduce and Compensation Solid Soft Starter

Figure 2-2   Vector of reactive power compensation
As can be seen from the figure, in the motor-side to provide reactive power, the current I absorbed from the system decreased significantly.
Reactive power control cabinet and reactive power generator form the reactive power control system, timely to control reactive power generator to provide a reasonable reactive power.
