Description

Technical Field

[0001] The utility model relates to the technical field of power towers, in particular to a measuring system capable of effectively monitoring operating parameters of power towers. Background Art

[0002] The mechanical ventilation cooling tower (referred to as the mechanical tower) is an important part of the cold end system of the power plant. Its cooling efficiency affects the vacuum degree in the condenser, and thus affects the cycle thermal efficiency of the entire thermal system. The relevant protections set around the mechanical tower fan are not only an effective means of monitoring the working status of the mechanical tower fan, but also a strong line of defense to ensure the safety of operating personnel and equipment.

[0003] At present, the main way to judge whether the mechanical tower fan is operating normally is to monitor the oil tank temperature, liquid level and vibration. In order to achieve the above parameter measurement, a three-in-one probe of temperature, liquid level and vibration is usually used, and the three-in-one probe is set inside the gearbox for inspection. In actual application, this method has poor measurement accuracy and reliability, especially for liquid level and vibration measurement, which often fails and seriously affects the safe operation of the mechanical tower fan.
