Scope of Application:

The digital arc suppression and harmonic elimination cabinet is suitable for 3~35kV medium voltage power systems. It is applicable to power systems with ungrounded neutral points or neutral points grounded via arc suppression coils. It is suitable for grids dominated by cable lines, mixed grids of cables and overhead lines, as well as grids primarily composed of overhead lines.

Overview:

The DLTXH digital arc suppression and harmonic elimination cabinet and PT cabinet (hereinafter referred to as the digital arc suppression cabinet) are used in 3~35kV three-phase non-directly grounded power systems to manage various overvoltages, improving grid operational reliability and power supply stability.

Basic Functions: When a single-phase arc grounding fault occurs, the digital arc suppression cabinet can activate the vacuum contactor of the fault phase within 30 ms, reducing the fault phase voltage to zero and extinguishing the arc. The cabinet then issues an action signal. For overhead lines, it can be set to automatically disconnect the vacuum contactor after 4-5 seconds. If the fault is transient, normal operation resumes; if it is permanent, the contactor reactivates and remains closed to provide overvoltage protection. After the faulty line is removed, manual reset via a button or remote control is required to restore the digital arc suppression cabinet to its normal state. DLT-XH
