Embodiment 1

[0024] see figure 1 and Image 6 , the present invention provides a technical solution: an online pressure monitoring system for electric power oil-less equipment, including an oil reservoir 1, a plurality of pressure detection units are arranged inside the oil reservoir 1, and the pressure detection units are located in the oil reservoir 1 Collect pressure parameters inside, the pressure detection unit is electrically connected to a data acquisition terminal, the data acquisition terminal is electrically connected to a wireless transmission device, the wireless transmission device is connected to a central processing unit through a wireless signal, and the data acquisition terminal collects pressure The pressure parameters transmitted by the detection unit supply power to the pressure detection unit at the same time, display the pressure of the pressure detection unit on the spot, and transmit the pressure data to the data concentration unit through the wireless transmission ...

Embodiment 2

[0029] see figure 2 , image 3 and Image 6 , the difference from Embodiment 1 is that the locking device includes a fixed base 11, a plurality of fixed bases 11 are fixedly connected with the inner bottom surface of the oil reservoir 1 through bolts, and the fixed base 11 is far away from the oil storage A connecting rod 12 is fixedly connected in the middle of the end face of the device 1, and a connecting hole 13 is arranged in the middle of the lower end face of the sensor base 2, and the connecting rod 12 is threadedly connected with the connecting hole 13, and the sensor base 2 is manually rotated to make the sensor base 2 drive The connecting hole is connected with the connecting rod 12. The outer side of the fixed seat 11 and the sensor base 2 is provided with a sliding sleeve 14 to prevent the sensor base 2 from rotating. Between them, a spring A15 is connected to the outer side of the fixed seat 11. When the sensor base 2 is connected with the fixed seat 11 under ...

Embodiment 3

[0033] see Figure 4 , Figure 5 and Image 6 , the difference from Embodiment 1 is that the connecting member includes a sliding hole, and the sliding hole is evenly arranged on the inner side wall of the oil reservoir 1, and a sliding rod 18 is slidably connected in the sliding hole, and the sliding rod The upper end of 18 is fixedly connected with the lower end surface of lifting plate 7, and one side of the outer surface of the limit rod 18 is provided with locking grooves 19 in turn from top to bottom, and the side wall of the oil reservoir 1 is provided with a sliding The working hole connected to the side wall of the hole, the locking post 20 is slidably connected in the working hole, and the locking post 20 cooperates with the locking slot 19. When the sliding rod 18 moves down along the fixed hole, the locking slot 19 Simultaneously move down along the fixing hole, and in the process of moving down again, under the effect of the spring B22, the locking post 20 and t...

Abstract

The invention discloses an on-line pressure monitoring system for power oil-less equipment. A plurality of pressure detection units are arranged in the oil reservoir and are electrically connected with a data acquisition terminal; the data acquisition terminal is electrically connected with wireless transmission equipment; the wireless transmission equipment is connected with a central processingunit through a wireless signal; the central processing unit comprises a data concentration unit; the central processing unit is connected with background monitoring software through a wireless transmission signal; the pressure detection unit comprises a sensor base; the upper end of the sensor base is fixedly connected with a sensor. According to the design, the pressure value of the electric power oil shortage equipment can be monitored in real time, through background processing and analysis, watch men can observe in time, the safety is improved, and through cooperation of the sensor base, the annular clamping groove, the limiting groove, the threaded rod, the lifting plate, the limiting column, the fixing rod and the clamping block, the sensor base and the sensor can be rapidly connected with the side wall of the oil storage device.

Description

technical field [0001] The invention relates to the technical field of electric power oil-less equipment, and specifically relates to an online pressure monitoring system for electric power oil-less equipment. Background technique [0002] A substation is a power facility in the power system that transforms voltage, receives and distributes electric energy, controls the flow of power, and adjusts voltage. It connects the power grids of all levels of voltage through its transformers. The operating substation equipment needs to master its safety performance. As oil-filled power equipment, when thermal faults and electrical faults occur, the insulating oil and insulating paper will be decomposed to produce gas, which will be dissolved in the oil according to certain rules. Therefore, the detection of dissolved gas in insulating oil has become the most effective method. Safety detection method, hidden failures that cannot be found in time will develop into failures or accidents,...
