Embodiment Construction
[0012] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.
[0013] A small steam turbine low-pressure main steam valve travel test control system. The low-pressure main steam valve of the feed pump of the small steam turbine is controlled by two systems: the emergency shutdown protection system (ETS) and the electro-hydraulic control system (MEH). The ETS system is controlled by the control panel and Cabinets, field devices and interconnected cables, the control panel has high and...
