A method for detecting a leak in a large circuit breaker
ActiveCN115993211BRealize automatic baggingreduce manual laborDetection of fluid at leakage pointLifting framesLeak detectionCircuit breaker
This invention relates to a leak detection method for large circuit breakers. First, the components constituting the large circuit breaker, including the poles, base, and operating mechanism, are assembled on a pallet. Then, the entire pallet is transported to a dedicated bagging system for bagging. The poles are bagged using the dedicated bagging system. The large circuit breaker is then wired to the pallet, and the pallet is wired to a break-in device. The break-in device begins operation to test for SF6 gas leakage during the operation of the large circuit breaker. The SF6 content in the gas inside the PE sealed bag is detected to determine if a leak has occurred. This leak detection method, using a dedicated bagging system, achieves automated bagging of the large circuit breaker, eliminating the need for manual top-down bagging of the poles, significantly reducing manual labor and eliminating the need for manual climbing, thus preventing safety accidents.

A method for on-line troubleshooting of a cold rolling annealing furnace radiation tube
This invention discloses an online troubleshooting method for radiant tubes in a cold rolling annealing furnace. It involves collecting and establishing a baseline dataset of CO, CO2, and O2 concentrations in each layer of flue gas branch pipes under normal production conditions. During normal furnace operation, the CO concentration ai1 in each layer of flue gas branch pipes is monitored in real time. When the CO concentration ai1 in the i-th layer of flue gas branch pipe exceeds the baseline range, a troubleshooting mechanism is triggered. The operating status of each radiant tube in the i-th layer is retrieved and monitored, and the dynamic response of the CO concentration in that layer of flue gas branch pipe is monitored simultaneously. Step S4: Multiple rounds of iterative troubleshooting are repeated to confirm all faulty radiant tubes and shut them down. Subsequently, it is verified whether the flue gas composition has returned to the baseline range. This method solves the technical problems of existing technologies, such as the need for machine shutdown for radiant tube leak detection, high reliance on manual labor, and high misjudgment rate.
