The guaranteeing systems mostly comprise components such as pipelines, valves, circulating pumps and the like, and if the components cannot be timely processed when faults occur, the phase modulator can be tripped, and further the operation safety of a power grid is affected.
When parts such as a motor, a valve or a circulating pump have faults, the parts are difficult to maintain in a short time, and therefore the parts with the faults need to be replaced in time.
