Problems solved by technology
In order to make the factory system more stable, when the inverter of the factory system stops running, there will be a spare inverter automatically activated, but it is still impossible to avoid the instantaneous voltage drop when switching, causing the equipment in the factory system to crash, and the Affect the efficiency of the factory system, and even cause the shutdown of process equipment
In addition, there is currently no monitoring for the cooling fan, so it is impossible to know the running status of the fan inside the inverter
Even if the speed of the cooling fan slows down or stagnates due to failure or dirt, the temperature of the inverter will not rise rapidly immediately, so the temperature sensor cannot warn in time, causing the equipment in the factory service system to crash due to pressure drop

Embodiment Construction
[0023] see figure 1 , figure 1 is a schematic diagram of the working system 10 of the first embodiment of the present invention. The working system 10 may include a working device 12 , a fan 14 , an air duct 16 , a buoy 18 , a float 20 , an air volume regulating valve 24 , a warning device 26 and a detector 22 . The fan 14 is used to generate wind to dissipate the heat energy generated when the working device 12 is in operation. The working device 12 is used to execute instructions. In this embodiment, the working device 12 is an example of a frequency converter, but any device that requires a fan 14 to dissipate the heat generated during the operation of the working device 12 belongs to the scope of the present invention. The air duct 16 is in communication with the fan 14 and is used to guide the direction of the wind force. The buoy 18 is connected to the air duct 16, and the buoy 18 is substantially vertical to the horizontal plane, so that wind force can enter the buoy...

The invention discloses a work system with an alarming prediction function, comprising a working device, a fan, a wind pipe, a float bowl, a floating ball and a detector. The fan is used for generating wind power so as to radiate heat generated by the working device in operation. The wind pipe is communicated with the fan and used for guiding direction for the wind power. The float bowl is linkedwith the wind pipe and internally provided with the floating ball which can suspend in the float bowl by the wind power guided into the float bowl. The detector is arranged adjacent to the float bowland suitable for generating an alarming signal when the floating ball is positioned at a preset position in the float bowl.
Description
【Technical field】 [0001] The present invention relates to a working system, in particular to a working system with an alarm prediction function. 【Background technique】 [0002] The inverter used in the factory system uses a small fan to reduce the temperature to prevent the inverter from malfunctioning due to overheating. A temperature sensor is installed inside the frequency converter. Once the temperature of the frequency converter exceeds the preset temperature, the frequency converter will be forced to stop to protect the frequency converter itself. In order to make the factory system more stable, when the inverter of the factory system stops running, there will be a spare inverter automatically activated, but it is still impossible to avoid the instantaneous voltage drop when switching, causing the equipment in the factory system to crash, and the The efficiency of the factory system is affected, and even the process equipment is shut down. In addition, there is curre...
