Abstract

Low - voltage main switch or only the monitored switch of any size can thus be mechanically switched without current, via the electronic control by the electronic switching actuator connected in series! The new feature is that the switching state of the switch is electronically monitored and, via this monitoring, the load is only switched on in the closed state by the electronic switching actuator. Thus, the switching spark and the current load on the contacts are much lower and thus could be done in the DC circuit and the size of the switch in the AC circuit. The switching frequency as a life cycle, would therefore also increase many times over. See drawing and procedure of the switching operations. Siemens has developed similar switches and it is currently trying much, the parallel control z. B. performed in high voltage networks, but which seem to me to be complicated and also not reflect the mechanical safety of the open contact. The compact design as a complete switch unit is shown here in the appendix as a system of a functional unit.

Description

Electromechanical (pos. 2 ) and electromagnetic (pos. 3 ) Switch in power electronic series connection (pos. 5 ) or (pos. 8th ) for powerless switching of the mechanical switch (pos. 2 ) and for galvanic separation in case of danger (Pos. 2 ) It is a power supply (pos. 4 ) low power needed! About the connection (pos. 7 or pos. 9 ) the consumer is to be installed. Pos. 1 is the connection for the NS supply line from the respective distribution pos. 6 is a connection to the additional possibility of control via a galvanically isolated control contact from a remote control!

• 1. A circuit breaker for emergency or incidents during manual operation
• 2. In the AC circuit, ensure that a predetermined zero point in the AC period.
• 3. In the DC circuit that prevent an arc through Mos Feet switch
• 4. Delays of switching operations to minimize contact load.
• 5. be able to carry out remote circuits in the normal mode.

shifting sequence general condition 1. Mechanical switch Out starting position Electronic switch Out OUT Second Mechanical switch One switch-on Electronic switch Out Out Third Mechanical switch One Switch "ON" Electronic switch A (delayed) ONE upturned Switch "off" 4th Mechanical switch One off operation Electronic switch Out OUT 5th Mechanical switch Off (delayed) Switch "OFF" Electronic switch Out OUT

The switch switches without sparking and by the zero point with alternating voltage or three-phase circuit, despite mechanical circuit With DC one can connect a MOS field effect transistor in series and in the same way prevent the sparking and high contact loads. Another advantage is that you can use the electronic switch to control the connected end user and thus save distribution size and waste heat as power losses.

The compact design as a complete switch unit is shown here in the appendix as a system of a functional unit. Remote switching and discharge of waste heat is thus possible in this simple way. It is thus possible to switch from remotely located distribution boards or via the Internet, reducing the waste heat from the distribution by means of galvanically isolated relays (optical relays), additional switching operations can be carried out with the mechanical switch closed.
