Application condition and scheme of Siemens dual power switch

Siemens dual power switch application conditions

The ESD standards in pieces

ESD guidelines must be followed when handling dual power switch 3KC4 and 3KC8 series devices.

◆ Electrostatic Sensitive Device (ESD)

ESD sensing elements can be destroyed by voltages and energies far below the human perception threshold, which occurs at the moment when a person touches the device or equipment without ESD treatment. ESD components that suffer from this voltage are usually not immediately identified as defective because such failures do not occur until after the equipment has been operating for a long time.

Note:

1. Electrostatic sensitive equipment

Electronic modules contain components that can be damaged by electrostatic discharge. These modules can easily be corrupted by incorrect operations.

● The body must release its own static electricity before contact with electronic devices. This is done by direct contact with an earthed conductor, such as an exposed metal part of a switchgear or water pipe.

● Always hold onto the plastic casing of the device.

● Electronic modules should not be in contact with electrical insulation materials, such as plastic film, plastic parts, insulating desks or cloth made of man-made fibers.

● Always place the electrostatic sensitive device on the conductive body.

● Always store and transport electronic modules or devices in ESD secure conductive packaging, such as metallized plastic or metal containers, and always place devices in their packaging prior to installation.

2. Storage and transportation

If you must store or transport the device in non-conductive packaging, you must first wrap the device in ESD safe conductive material, such as conductive foam rubber, ESD package.

Siemens dual power switching applications

In toggle switch applications, the dual power toggle switch is described here as an innovative solution to complex source requirements. To monitor and control the source, an appropriate and independent Siemens dual power toggle switch controller must be used with the 3KC4 model.

The meanings of the symbols shown in the circuit diagram are as follows:

The following table shows the toggle switch behavior. The following code indicates the availability of the source (transformer or generator) :

●1= source available;

●0= source unavailable;

● X = undefined source availability is meaningless.

The switching state of the dual power switch is described as follows:

●P1=P1 switch closed;

●P2=P2 switch closed;

●P3=P3 switch is closed, etc.

● X = nonsense (a toggle switch can be in any of three switching states I, 0, or II).

The following application scheme is suitable for Siemens dual power switch 3KC8 (with electronic module) and 3KC4 (with appropriate and independent switch controller).

◆ Switching application scheme of two-channel power supply and single-bus power supply

Switch (T1 (kVA) = T2 (kVA))

Switching switches can be used to switch between two sources of equal power (T1(kVA)=T2(kVA)) when there is an output load. The Siemens dual power switching 3KC8 series provides an ideal solution for power grid, power grid applications and power grid and generator applications, as shown in the figure below.

◆ Switching application scheme of two-channel power supply and single-bus segmented power supply

Switch (T1(kVA) > T2/G(kVA))

In this application, the power of source I is greater than that of source II (T1(kVA) > T2/G(kVA)). This application usually USES a generator and a transformer, but for this application the Siemens dual power switching switch 3KC8 can also be converted between two transformers. In this case, the load can be divided into important load and non-important load, as shown in the figure below.

By using two switching switches, a complex application consisting of three equal power sources (T1(kVA)=T2(kVA)=G) can be implemented to enable the power supply to be maintained, as shown in the figure below.
