How to maintain and manage the outdoor load disconnect switch?

Regular Maintenance:

  • Visual Inspection: Conduct regular visual inspections to ensure that the switchgear's housing, connection points, and seals are free from obvious damage or corrosion.

  • Internal Inspection: Perform regular internal inspections, particularly of critical components such as the arc quenching chamber, contacts, and insulating parts, to ensure they are in good condition.

  • Functional Testing: Carry out regular functional tests, including opening and closing operations, insulation resistance testing, and dielectric strength testing, to ensure all functions of the switchgear are operating correctly.

Gas Pressure Monitoring:

  • Pressure Monitoring: For outdoor load break switches using SF6 gas, regularly monitor the SF6 gas pressure in the arc quenching chamber to ensure it remains within the specified range.

  • Leakage Detection: Use leakage detection equipment to regularly check for SF6 gas leaks, and address any detected leaks promptly.

Environmental Control:

  • Temperature Control: Control the installation environment's temperature to avoid high or low temperatures that could affect the performance of the switchgear.

  • Moisture Protection: Implement moisture protection measures to prevent water from entering the switchgear, which could impact its insulation performance and the normal operation of mechanical components.

Underground Power Cable Transmission LinesDirect - buried power cable lines have large ground - distributed capacitance, causing high single - phase - to - ground short - circuit capacitive current. For 10 kV lines, if this current exceeds 10 A, arcs hardly self - extinguish, risking arc overvoltage and endangering line equipment. Arc extinction is thus necessary. With a Dyn - connected main transformer, an arc - suppression coil on the secondary neutral point suffices. For Yd - connected ones,

I. Core Cause of Damage: Electrodynamic Impact (Complying with GB/T 1094.5 / IEC 60076-5)The direct cause of high-voltage winding end collapse is the instantaneous electrodynamic impact induced by short-circuit current. When a single-phase grounding fault occurs in the system (such as lightning overvoltage, insulation breakdown, etc.), the grounding transformer, as the fault current path, withstands high-amplitude and steep-rise-rate short-circuit currents. According to Ampère's force law

Zero-Sequence Impedance Characterization of Dry-Type Grounding Transformer with ZN Connection
In a neutral-insulated three-phase power system, an earthing transformer provides an artificial neutral point, which can be solidly earthed or earthed via reactors/arc suppression coils. The ZNyn11 connection is typical, where zero-sequence magnetomotive forces in the inner/outer half-windings of the same core column cancel out, balancing fault currents in series windings and minimizing zero-sequence leakage flux/impedance.Zero-sequence impedance is critical: it determines fault current magnitud

Case Analysis on Maloperation of Grounding Transformer Overcurrent Protection Relay
The neutral grounding mode refers to the connection between the power system neutral point and ground. In China's 35 kV and below systems, common methods include ungrounded neutral, arc-suppression coil grounding, and small-resistance grounding. The ungrounded mode is widely used as it allows short-term operation during single-phase grounding faults, while small-resistance grounding has become mainstream for its fast fault removal and overvoltage limitation. Many substations install grounding tr
