The KCS series thyristor throw switch is a power electronics product that can be used to connect power capacitor loads to the grid. This product is specialized for applications requiring the installation of switching devices and control devices, and allows for the fast switching of pure capacitor or reactance (up to 14%) step-by-step compensation systems. It is possible to compensate not only symmetrical three-phase currents, but also single-phase step-by-step compensation of the grid.

安全事项 Security matters

由于设计为风扇散热，必须保证空气入口畅通，不能覆盖散热器出口。必须注意与附近元件的距离。对于额定负荷，新鲜空气与排出空气的温度差会增加40℃。像电缆管道这样的温度敏感部件必须用套管保护起来。

必须在串联断路设备的条件下工作。

不能作为独立的器件工作，必须在某个补偿单元里使用。

必须在满足使用条件的场合应用。

甚至当本投切开关按照规定条件使用时，也不能避免本投切开关故障。在这种情况下，负载电路的电流和电压都会受到影响。故障情形下，可能会发生下面的情况：电流中断，半波运行或持续能量流失。因此，在项目设计阶段，要保证保护设备设计的正确性。

操作或接线错误会导致设备或负载的损坏。

必须用带有绝缘保护的电缆街头连接。

此设备的安装，维护和服务等工作必须由熟练的电工来操作完成。当本投切开关连接到供电系统时，容性负载( 电容) 将充电到电网电压峰值。这就意味甚至当开关断开时，负载仍是带电的，依然连接在电网上。因此，当安装和维护工作进行时，在任何情况下，都必须

从电网断开。否则有生命危险！

从电网断开后，容性负载中仍然有残余电压。在安装和维护工作前，必须检查电容器是否带电。必须考虑电容器的放电时间。

在串联电抗器时，要充分考虑电网的复杂性，特别是针对固定次数的谐波信号进行消谐时，有可能会放大其他次数的谐波信号，建议使用带有谐波保护功能的无功补偿控制器，否则会由于电荷传导的影响而损坏本开关。

Reactive po wer dynamic r egulator (c apacitive non-contact swit ch)

Since the design is for fan cooling, the air inlet must be kept clear and must not cover the heat sink outlet. Attention must be paid to the distance from nearby components. For rated loads, the temperature difference between fresh air and exhaust air can increase by 40° C. Temperature sensitive components like cable ducts must be protected with sleeves.

Must work under the condition of a series break device.

Cannot work as a stand-alone device and must be used in some compensation unit.

Must be applied where the conditions of use are met.

Even when this throw switch is used according to the specified conditions, a failure of this throw switch cannot be avoided.

In this case, the current and voltage of the load circuit are affected. The following situations may occur in a fault situation: current interruption, half-wave operation or continuous energy loss. Therefore, during the design phase of the project, it is important to ensure that the protection equipment is designed correctly.

Operating or wiring errors can lead to damage to equipment or loads.

Street connections must be made with cables with insulation protection.

The installation, maintenance and service of this equipment must be performed by a skilled electrician. When this throw switch is connected to the power supply, the capacitive load (capacitor) is charged to the peak grid voltage. This means that even when the switch is disconnected, the load is still charged and connected to the grid. Therefore, when installation and maintenance work is carried out, it must be disconnected from the grid in all cases. Otherwise there is a risk to life!

After disconnection from the grid, there is still residual voltage in the capacitive load. Before installation and maintenance work, the capacitors must be checked for charging. The discharge time of the capacitor must be considered.

When connecting reactors in series, the complexity of the grid must be fully considered. Especially when detuning for a fixed number of harmonic signals, it is possible to amplify other numbers of harmonic signals and it is recommended to use a reactive power compensation controller with harmonic protection, otherwise this switch can be damaged due to the influence of charge conduction.

This throw switch is particularly suitable for applications with rapidly changing loads in terms of frequency and reactive power. The advantages of this switch compared to conventional technology are:

-Fast switching speed -Low pollution of the system during switching

-No wear parts during switching - Long service life and unlimited operating frequency

Application areas:

-Crane equipment -Lifters -Welding equipment -Molding -Wind turbines

This throw switch can work with reactive power controllers, programmable controllers, computer systems and process control units.

安装 Installation

本投切开关可以水平或垂直安装。由于强制散热，所有产生的暖空气几乎从一个方向排出。在最大负荷下，预计有最大40K 的温升。

如果系统中有温度敏感元件，像电缆管道，就必须用套管保护起来。

扇侧：>50mm 散热出口：>150mm

如果垂直安装，必须保证散热空气从上面排出。注意：垂直安装时，应防止异物掉入散热器中而导致风机损坏，所以在安装时须用防护板之类的物品将散热器罩住，在测试和运行前再将防护板拆除。

This throw switch can be installed horizontally or vertically. Due to forced heat dissipation, all generated warm air is discharged from almost one direction. At maximum load, a temperature rise of up to 40 K is expected. If there are temperature sensitive elements in the system, like cable ducts, they must be protected with sleeves.

Fan side: >50 mm Heat dissipation outlet: >150 mm

If installed vertically, it must be ensured that the cooling air is discharged from above. Note: When installed vertically, foreign objects should be prevented from falling into the radiator and causing damage to the fan, so the radiator must be covered with a protective plate or something like that during installation, and then removed before testing and operation.
