KRIntroduction to Series Voltage Switching Devices

●The KR series voltage switching device is a multifunctional and intelligent parallel device developed and designed based on the continuous development of the current power supply system.

●This product has the functions of voltage reset and parallel connection. It can effectively solve PT maintenance or a PT fault in a certain section, and replace the voltage measurement and protection function of this section with another PT voltage working in the same system.

●KR-3520F is suitable for power supply systems with multiple busbars and PTs operating in the same system. It is a non-standard product that can be developed and designed according to site and user requirements, and can carry up to 4 types of busbars and PTs.

●KR-3520 is suitable for two sections of busbars in the same system, and can achieve voltage parallel switching, manual remote control, switching signal output, etc.

●KR-2520 is suitable for two sections of busbars in the same system and can achieve voltage parallel switching.

Main functions

●Dual PT voltage parallel function for protecting windings and measuring windings

●Manual/remote control switching selection

●Switch signal output

●The status of the switchgear busbar is used as a parallel criterion
