| Relay device as the last defense line of the power grid, is the key to the safe and reliable operation of the power grid. Its function is to reduce the down time, reduce the power range and reduce the fluctuation of power grid. According to the relevant regulations, all the equipment and its external circuit wiring in new since the device is put into operation and put into operation after the test needs within the prescribed period of time. But in actual operation, which is often malfunction occurs between two maintenance, to the power grid security. In order to prevent the emergence of such a situation, the state protection equipment maintenance born.In recent years, the community supply reliability is extremely demanding, and if regular check on the inspection in accordance with regulations, would inevitably lead to extended testing of protective equipment. Therefore, protection equipment Huangdao Power Grid, to take a comprehensive evaluation of the health of their way, according to the quality of the actual operating conditions, operating environment, operation and maintenance status of the equipment, etc., and meta-analysis equipment, supplemented by data in real-time online monitoring data, combined with abnormal recording routine equipment operation and defect records, establish a scientific and comprehensive evaluation of the state system. Huangdao Power Grid in accordance with the evaluation rules divided into different levels. The equipment operation further quantified to determine the repair strategy differentiated devices targeted for protection equipment debugging:After evaluating the health status of the poor protection equipment to shorten the maintenance cycle, reduce failure; and for good health equipment, maintenance can be appropriately less or no maintenance, to ensure commissioning work "should be compulsory repair, maintenance mandatory good", to ensure the stable operation of the protection device to ensure the safe operation of Huangdao Power Grid. |
