Maintenance and troubleshooting guidelines for a typical high

Maintenance RequirementsPreparation Before MaintenanceMaintenance ProcedureSwitchgear SparesLubrication of Operating MechanismsTroubleshooting GuideMaintenance covers a wide range of activities, all of which are required to keep the switchgear in ready condition at all times to enable it perform its functions satisfactorily. The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance.

Density of Sulfr hexafluoride Measurement: Gas Density Indicator GDI-100-D

sf 6 Density OverviewMonitoring gaz sf6 Density with Gas Density IndicatorsGdi-100-D For Extreme Accuracy and Ease of UseSulfur hexafluoride (Sulfr hexafluoride) is an extremely effective electrical insulator used in a variety of applications, especially in medium- and high-voltage gas-insulated equipment (GIE) like switchgears, disconnectors, transducers, transformers, and ring main units. If GIE relied on air or N2 alone to extinguish electric arcs, it would have to be almost three times as large. But to maintain proper insulation, the density of insulating gasinside the equipment must remain within certain levels. What would cause the gas density to drop in the first place? There are two reasons, and they’re interrelated: 1. Over time, GIE could develop tiny fissures that allow sf6 gas to escape. Fugitive emissions means there’s less insulating gas inside the chamber. What’s more, as Sulfr hexafluorideis a powerful greenhouse gas, any leaks harm the environment. 2. In the presence of fissures, air could enter the GIE. Ambient air is problematic because it contains water vapor, which combines with sulfur and fluorine molecules after an electri...Get price
