1. Definition of Condition-Based MaintenanceCondition-based maintenance refers to a maintenance method where decisions on whether and how to perform maintenance are determined based on the real-time operating status and health condition of equipment. It has no fixed maintenance methods or schedules. The prerequisite for condition-based maintenance is the establishment of equipment parameters and the comprehensive analysis of various operational information of the equipment, so as to make reasona

Simplicity means fewer components. According to the principle that system reliability equals the product of individual component reliabilities, fewer parts lead to higher reliability.For PT trolleys in air-insulated switchgear, a simplified drawer-type design is adopted. On the cable compartment side, the PT trolley eliminates the need for a 200mm chassis to rack in and dispenses with blossom contacts. Instead, it uses the PT’s built-in fuse and striker mechanism, making direct contact

What is GIS Equipment?GIS is the English abbreviation for Gas Insulated Switchgear, which is fully translated into Chinese as Gas-Insulated Metal-Enclosed Switchgear. It typically uses sulfur hexafluoride (SF6) gas as the insulating and arc-quenching medium. GIS integrates, through optimized design, the main primary equipment in a substation—excluding the transformer—such as circuit breakers (CB), disconnectors (DS), earthing switches (ES/FES), busbars (BUS), current transfor
