Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dissolved gas monitoring in oil, and particularly relates to a real-time monitoring device for dissolved gas in oil. Background Art
[0002] Dissolved gas monitoring in oil is a technology used to evaluate the operating conditions of oil-immersed electrical equipment such as power transformers. The gas components and contents in transformer oil can reflect the insulation fault conditions inside the equipment. Therefore, DGA is an important monitoring means for fault diagnosis of oil-immersed power equipment in the power system. By monitoring the dissolved gas in oil, potential faults inside the transformer, such as partial discharge, overheating, and arc discharge, can be detected in a timely manner, so as to achieve early warning of faults. The principle is that different types of faults will generate specific gas combinations, and by analyzing the types and contents of these gases, the fault types can be diagnosed.
[0003] In the monitoring of dissolved gas in oil, sealing performance is a very important factor, which directly affects the accuracy and reliability of monitoring results. If the sealing performance is insufficient, it is easy for external gases to mix in or internal gases to escape, affecting the measurement of gas concentration, resulting in inaccurate analysis results and being unable to reflect the true situation inside the equipment. At the same time, there is also a situation of polluting the external environment. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a real-time monitoring device for dissolved gas in oil. After the sealing device is fixed, the sealing strip on the inner circle of the mounting plate seals the outer wall of the reinforcing plate. At the same time, the reinforcing strips on the clamping plates on both sides can increase the friction between the clamping plates and the reinforcing plate, and the sealing device can be stably fixed on the outside of the reinforcing plate. The sealing device can improve the sealing performance of the device, avoid the leakage of gas in the oil due to poor sealing of the monitoring equipment, which affects the measurement of gas concentration and makes the analysis results inaccurate, and at the same time prevent the leakage of oil samples and gases, polluting the environment. It solves the problems that if the existing sealing performance is insufficient, it is easy for external gases to mix in or internal gases to escape, affecting the measurement of gas concentration, resulting in inaccurate analysis results and being unable to reflect the true situation inside the equipment, and there is also a situation of polluting the external environment.

Specific embodiments
[0035] Please refer to Figures 1-5 , the present utility model is a real-time monitoring device for dissolved gases in oil, including a transformer oil pipe 1, with a flange butterfly valve 2 fixed at one end of the transformer oil pipe 1; one end of the flange butterfly valve 2 is connected to a connecting pipe 3, one end of the connecting pipe 3 is fixed with a reinforcing plate 4, a polyimide film 5 is fixed inside the reinforcing plate 4, and a gas chamber 6 is fixed at one end of the reinforcing plate 4; a sealing device 7 is sleeved outside the reinforcing plate 4, and the sealing device 7 includes a mounting plate 8; an adjustment groove 9 is formed on the surface of the mounting plate 8, and a support plate 10 is fixed on the outer circle of the mounting plate 8; positioning rods 11 are fixed on both sides of the support plate 10; an adjustment plate 12 is slidably connected inside the adjustment groove 9, through holes 13 are formed on the surface of the adjustment plate 12; the positioning rods 11 penetrate through the through holes 13; a clamping plate 14 is fixed on one side of the adjustment plate 12, and a number of springs 15 are fixed on one side of the adjustment plate 12.
[0036] Specifically, a limit plate 16 is fixed at the top of the positioning rod 11, and the other end of the spring 15 is fixedly connected to the limit plate 16; fixing plates 17 are fixed at both ends of the mounting plate 8, and the mounting plate 8 is integrally in an "Ω" structure; a number of positioning holes 18 are formed on the surface of the fixing plate 17, and threaded rods 19 are threadedly connected inside the positioning holes 18; a number of reinforcing strips 20 are fixed on both sides of the inner wall of the clamping plate 14, and the reinforcing strips 20 are made of rubber material; a sealing strip 21 is fixed on the inner circle of the mounting plate 8, and the sealing strip 21 is made of rubber material.
[0037] Furthermore, a transmission pipe 22 is fixed at one end of the gas chamber 6, a solenoid valve 23 is fixed outside the transmission pipe 22; one end of the transmission pipe 22 is fixed with a sensor chamber 24, and an instrument part 25 is fixed at one end of the sensor chamber 24.
[0038] The operation process of this embodiment is as follows: When this device is in use, the polyimide film 5 fixed inside the reinforcing plate 4 effectively separates the dissolved gases in the transformer oil. After the polyimide film separates the fault characteristic gases in the oil, such as hydrogen, carbon monoxide, carbon dioxide, methane, etc., from the oil, the gases enter the sensor chamber 24 for detection. Hydrogen sensors, carbon monoxide sensors, carbon dioxide sensors, etc. can be installed in the sensor chamber 24 according to the usage requirements, and the results are output in the instrument section 25. During this process, in order to avoid leakage when separating the gases from the oil, a sealing device 7 can be fixed on the outer side of the reinforcing plate 4, that is, two mounting plates 8 are clamped on the outer side of the reinforcing plate 4, and the clamping plates 14 on both sides clamp the reinforcing plate 4. Then, the threaded rod 19 is screwed into the positioning hole 18 to fix the mounting plate 8. After the sealing device 7 is fixed, the sealing strip 21 inside the mounting plate 8 seals the outer wall of the reinforcing plate 4. At the same time, the reinforcing strips 20 on the clamping plates 14 on both sides can increase the friction between the clamping plates 14 and the reinforcing plate 4, making the sealing device 7 more stably fixed on the outer side of the reinforcing plate 4. The sealing device 7 can improve the sealing performance of this device, avoid the leakage of the gases in the oil due to the poor sealing performance of the monitoring equipment, which may affect the measurement of the gas concentration and lead to inaccurate analysis results. At the same time, it can prevent the oil sample and the gas from leaking and polluting the environment.
