This series of comprehensive analyzer is a multi-functional intelligent switch analog comprehensive dynamic indicating device developed and designed for the current development of medium voltage system switch technology, which is mainly used in various indoor switch cabinets with voltage level of 0.1 ~ 40.5KV.
The SW-DLZ300 phase-to-ground short-circuit monitoring and protection device is used in combination with a display host (optional), a single phase-to-ground short-circuit protection device and a high-precision zero-sequence current transformer. One display host and multiple single phase-to-ground short-circuit monitoring and protection devices are installed in each low-voltage cabinet to manage multiple outgoing circuits. The display host group is responsible for parameter setting and local display, and RS485 communication mode is used for numerical setting and data display with multiple single-channel short-circuit monitoring and protection devices; the single-channel phase ground short circuit monitoring and protection device is responsible for collecting zero sequence current, zero sequence current calculation, zero sequence current primary and secondary isolation conversion, fixed value setting (parameter setting and fixed value setting can be performed by computer software when there is no display host), protection logic judgment control, trip control outlet and other functions, and has independent communication function with the upper computer, and can be flexibly configured according to the site conditions.
Real-time monitoring: real-time display of the zero-sequence current of the monitored line is helpful for maintenance personnel to accurately judge the insulation status of the system and make maintenance plans.
