In modern power systems, oil circuit breakers play a critical role as essential components for controlling and protecting electrical circuits. Whether the system is operating under no-load, full load, or during a short-circuit fault, the oil circuit breaker must be able to operate reliably, either opening or closing when required. This reliability is crucial for maintaining the stability and safety of the entire power grid.

Proper maintenance of oil circuit breakers is vital to ensure their continued safe and efficient operation. Here are key points to consider during the maintenance process:

(1) The rotating parts of the oil circuit breaker should move smoothly without any jamming or deformation. Any sign of damage should be addressed immediately.

(2) The arc extinguishing system must be correctly positioned, with no misalignment between the upper and lower sections. The arc chamber should be free from cracks or burn marks, and the center hole diameter should meet quality standards.

(3) The static contact must be installed in the correct orientation to ensure proper alignment and function.

(4) The movement of the moving contact should comply with the manufacturer’s specifications to ensure proper performance.

(5) The three-phase synchronization distance must be within the allowed limits to maintain balanced operation.

(6) The opening and closing times of the oil circuit breaker must match the specified requirements to ensure reliable operation.

(7) The trip link must be adjusted properly to ensure that the oil circuit breaker can remain in the correct working state and trip reliably when needed.

(8) The insulation cylinder should be intact, undamaged, and the bakelite ring must be complete to ensure good insulation performance.

(9) All sealing gaskets must be in good condition and free from leaks to prevent oil loss and maintain system integrity.

(10) The copper-tungsten alloy block on the arcing contact of the static contact should not be severely burned. If the burning area exceeds one-third, it should be replaced immediately.

(11) The fingertip shrapnel should be in good condition, with appropriate contact pressure and reliable positioning to ensure stable operation.

(12) The check valve on the contact seat should function properly and move freely to ensure correct operation.

(13) The surface of the moving contact should be smooth and straight, with an intact silver plating layer. The copper-tungsten alloy head must be securely fastened, and there should be no severe burning on the contact.

These guidelines are essential for ensuring the safe and reliable operation of the power system. Only through thorough and regular maintenance can we guarantee the safety of both personnel and equipment. It is highly recommended that maintenance staff pay close attention to these details during their routine inspections and servicing.
