The invention relates to the field of fluidized bed reactors, in particular to a fluidized bed reactor and application thereof. The fluidized bed reactor comprises a reaction device and a catalyst extracting device configured on the reactor and used for extracting a catalyst online. By configuring the catalyst extracting device on the fluidized bed reactor body, the obtained reactor can achieve real-time and online catalyst extraction under the condition that a catalyst reaction does not need to be interrupted, operation of the reaction is not damaged, and the property of the catalyst such asthe catalyst carbon deposition amount and species variation of carbon deposition, can be monitored in real time.

The invention discloses a hydraulic oil online monitoring device. The online monitoring device comprises a pressure and speed reduction unit and a monitoring module (4), wherein an inlet of the pressure and speed reduction unit is connected with a hydraulic system to be monitored, and an outlet of the pressure and speed reduction unit is connected with an inlet of the monitoring module (4). Due to the fact that the pressure and speed reduction unit is arranged and the monitoring module is arranged on the downstream side of the pressure and speed reduction unit, high-pressure and high-flow-rate hydraulic oil to be monitored is converted into low-pressure and low-flow-rate hydraulic oil on the premise that the normal use of the hydraulic system is not affected. Due to the reduction of the pressure and flow rate of the hydraulic oil to be monitored, the online monitoring safety of the hydraulic oil can be improved.

The invention provides a testing structure of a semiconductor, The testing structure comprises a first metal layer, a second metal layer, and a third metal layer. The first metal layer includes at least two ground metal wires arranged in parallel; and at least two oblong first metal blocks having the arrangement direction identical with that of the ground metal wires are formed between the two adjacent ground metal wires. The second metal layer includes a plurality of metal conductive posts that correspond to the first metal blocks and are connected to the tops of the first metal blocks. And the third metal layer consists of a plurality of oblong second metal blocks corresponding to the metal conductive posts; the second metal bocks are connected to the tops of the metal conductive posts and the arrangement direction of the second metal blocks is perpendicular to that of the ground metal wires. The testing structure has a simple structure; and the interlamination through-hole metal layer process can be reflected effectively. With a plurality of blocks with different testing distances, the on-line process window size can be fed back in real time and the process improvement can be promoted; and with the testing method, a defect can be localized rapidly; and the operation improvement effect can be fed back timely.

A sensor for monitoring the noise of an oil-immersed transformer provided by the present invention includes: a piezoelectric ceramic tube fastened by a fastening frame and a bushing, and between the piezoelectric ceramic tube and the fastening frame and the bushing There is an insulating pad between them; the piezoelectric ceramic tube, the fastening frame and the sleeve are packaged with a high temperature and transformer oil resistant material; the thermistor is installed inside the sleeve. The acoustic sensor provided by the present invention can be kept stable in transformer oil, and can withstand the high temperature when the oil-immersed transformer is in operation; and can measure the working temperature of the acoustic sensor through the built-in thermistor, thereby setting the sensitivity at the corresponding temperature, and then making The acoustic sensor can be normally used in the oil of the oil-immersed transformer, and the measured sound pressure signal is helpful to analyze the internal noise generation and propagation mechanism of the oil-immersed transformer, and can also achieve real-time monitoring of the performance of the oil-immersed transformer Purpose.
