MULTI-CONTACT SWITCHING SYSTEM WITH INDEPENDENT CONTROL OF SIX POWER CONTACT GROUPS HAVING A COMMON CONNECTION POINT Russian patent published in 2023 - IPC H02J9/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to devices for sectioning and redundant power lines, and is intended for switching, protecting the electrical network, metering electricity, monitoring the quality of electricity, controlling the amount and time of voltage shutdown in three-phase current distribution networks. The technical result of the invention is to provide the ability to perform the functions of switching, protection of the electrical network, electricity metering, power quality control, voltage control in three-phase current distribution networks with the ability to independently control six power contact groups having a common connection point, for partitioning and redundancy of six sections of the transmission lines. A multi-contact switching system with independent control of six power contact groups having a common connection point, contains six output switching elements for manual control, six switching elements for remote control, six control units for switching elements for remote control, a control unit for a multi-contact switching system, a unit for receiving and transmitting data, uninterruptible power supply. The proposed device allows switching and protecting power lines, electricity metering, power quality control, voltage control simultaneously in six power networks. In the event of a voltage failure in one of the power networks and its appearance in another, the device allows you to perform the functions of automatic switching on of the reserve by switching on the corresponding power contact groups. Also, the device allows you to partition the electrical network by dividing it into sections by disconnecting the corresponding power contact groups in case of damage in the power networks connected to the multi-contact switching system. Its application prevents the development of an emergency and allows to reduce the undersupply of electricity to consumers, reduce the losses of energy supply organizations and, thus, increase the reliability and efficiency of consumer power supply systems.

EFFECT: ability to perform the functions of switching, protection of the electrical network, electricity metering, power quality control, voltage control in three-phase current distribution networks with the ability to independently control six power contact groups having a common connection point, for partitioning and redundancy of six sections of the transmission lines.
