Description

Technical Field

[0001] The present invention relates to the technical field of gas leak detectors, and particularly to an SF 6 gas micro-leak detection device. Background Art

[0002] SF 6 The micro-leakage of SF 6 gas in GIS (Gas Insulated Switchgear) equipment and circuit breakers is a common but difficult-to-detect problem. Due to the excellent insulation and arc extinguishing properties of SF

[0003] gas, it is widely used in these devices. However, the micro-leakage phenomenon may cause a decrease in gas concentration, thus affecting the normal operation and lifespan of the equipment.

[0004] To address the problem of difficult detection of micro-leakage, a method of collecting first and then detecting can be adopted. Gas is collected near the suspected leakage part of the equipment, and then a highly sensitive sensor is used to detect the collected gas to determine whether there is micro-leakage and the location of the leakage. Once a leakage problem is found, the collected gas needs to be purified to remove SF 6 gas and other harmful substances. The purified gas can be safely discharged into the atmosphere.

[0005] In summary, for the difficult-to-detect micro-leakage phenomenon in SF 6 gas-insulated equipment and circuit breakers, it is indeed necessary to design a special device for detecting micro-leakage to timely discover and handle the SF 6 gas micro-leakage problem and ensure the normal operation and use safety of the equipment.

[0015] Preferably, a plurality of exhaust holes are arranged along the circumferential direction at the bottom of the pipeline of the exhaust pipe.

[0016] Preferably, the adsorption mesh plate is a sponge filter screen, and the purification mesh plate is an activated carbon filter screen.

[0017] SF 6 The detection method of the gas micro-leakage detection device is carried out as follows:

[0018] (1) Place the air collecting hood near the suspected leakage part of the equipment to collect gas, start the intake fan to generate negative pressure in the air collecting hood, and this negative pressure will suck the gas leaked into the air collecting hood, making it flow towards the inlet of the fan. Through the conduction combination of the intake pipe, the diversion elbow pipe, the threaded pipe and the threaded sleeve, these gases are led into the gas collecting tank;

[0019] (2) The gas accumulates in the upper half of the tank body of the gas collecting tank. Infrared SF 6 sensor is used to detect the concentration of SF 6 in the gas to judge whether there is a micro-leakage phenomenon. If SF 6 gas is detected, an alarm will be given;

[0020] (3) When the staff receives the alarm, it is determined that the equipment has a micro-leakage; the collected gas is purified and discharged. Rotate the knob to open the movable isolation baffle, and the gas flows downward to the lower half of the tank body. Start the atomizing spray. The gas after atomization sedimentation adsorption is pushed by the driving fan to flow upward along the gas collecting tank. During the rising process, it first passes through the adsorption mesh plate for adsorption and drying, then passes through the purification mesh plate for adsorption and purification, and finally the exhaust valve is opened to discharge.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In the above technical solution, the SF 6 gas micro-leakage detection device includes a gas collecting tank. The tank body of the gas collecting tank includes an upper half of the tank body and a lower half of the tank body. Among them, a movable isolation baffle is arranged between the upper half of the tank body and the lower half of the tank body. The top end of the tank body of the gas collecting tank is conductively connected with a leakage gas collection component, and the top end of the tank body of the gas collecting tank is conductively connected with an exhaust valve. A driving fan is arranged at the bottom of the gas collecting tank. An infrared SF 6 sensor is installed on one side of the upper half of the tank body; an atomizing spray component is installed in the lower half of the tank body. A stop gasket ring is installed on the lower side of the isolation baffle. An adsorption mesh plate and a purification mesh plate are sequentially placed from bottom to top on the upper end of the ring frame of the stop gasket ring. The lower end of the ring frame of the stop gasket ring is connected with an exhaust pipe;

[0023] The present invention discloses an SF 6 gas micro-leakage detection device. By setting a gas collecting tank, gas collection is realized for the suspected leakage part of the equipment. The tank body is divided into an upper half and a lower half. A movable isolation baffle is arranged between the upper half and the lower half, which can realize the isolation or connection between the upper half and the lower half, and meet the requirements of first collecting, then detecting, and then purifying and discharging. An infrared SF6 The sensor detects the concentration of SF in the collected gas to determine whether there is a micro-leakage phenomenon. If SF 6 gas is detected, an alarm is triggered. The staff then opens the movable isolation baffle to allow the gas to flow downward to the lower half of the tank body. The atomizing spray is started, and the gas after atomization, sedimentation, and adsorption accumulates at the bottom of the tank body. The driving fan is started to make the gas flow upward along the gas collection tank. During the upward flow, the gas first passes through the adsorption mesh plate for adsorption and drying, then passes through the purification mesh plate for adsorption and purification, and finally the exhaust valve is opened to discharge the gas. When the gas enters the exhaust pipe, due to the guiding effect of the exhaust pipe, the gas is guided to the lower half of the tank body. This layout ensures the uniform distribution of the gas in the tank body, making the subsequent atomizing spray process more efficient and uniform. The driving fan is set at the bottom mainly considering that SF 6 gas itself is heavier than air and has the characteristic of sinking. After starting the atomizing spray to remove impurities or moisture in the gas, the driving fan is immediately started to generate an upward driving force to overcome the sinking trend of SF 6 gas, so that it flows upward along the gas collection tank. Through the above steps, the micro-leakage problem of SF 6 gas in the equipment can be detected and handled in a timely manner, ensuring the normal operation and use safety of the equipment. 6 Description of the Drawings

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 4 shown, it shows the specific embodiments of the present invention: As Figures 1 to 4 shown, the SF 6 gas micro-leakage detection device disclosed by the present invention includes a gas collection tank 1. The tank body of the gas collection tank 1 includes an upper half of the tank body and a lower half of the tank body. An active isolation baffle 10 is arranged between the upper half of the tank body and the lower half of the tank body. The top end of the tank body of the gas collection tank 1 is conductively connected to a leakage collection assembly 3, and the top end of the tank body of the gas collection tank 1 is conductively connected to an exhaust valve 2. A driving fan is arranged at the bottom of the gas collection tank. An infrared SF 6 sensor 5 is installed on one side of the upper half of the tank body;

[0034] An atomizing spray assembly 4 is installed on the lower half of the tank body. A stop pad ring 7 is installed on the lower side of the isolation baffle. An adsorption mesh plate 8 and a purification mesh plate 9 are sequentially placed from bottom to top on the upper end of the ring frame of the stop pad ring 7. The lower end of the ring frame of the stop pad ring 7 is connected to an exhaust pipe 308.

[0035] During on-site use, when the staff receives an alarm and detects a relatively low SF 6 concentration, it can be preliminarily judged that there is a micro-leakage situation in the equipment. Although micro-leakage will not immediately cause equipment failure, if it is not dealt with in time, it may lead to the deterioration of the leakage situation and ultimately cause equipment failure. Therefore, the staff should promptly inspect and repair the equipment, find the leakage point and deal with it to ensure the normal operation of the equipment; when a relatively high SF 6 concentration is detected, it indicates that there is a serious leakage situation in the equipment. In this case, the staff needs to take rapid emergency measures to avoid equipment failure and safety accidents. The staff first locates the leakage position, finds the leakage point, and can use materials such as plasticine for temporary plugging to stop the leakage. Of course, this is only an emergency measure. In the long run, a comprehensive inspection and repair of the equipment are still required to completely solve the leakage problem.

[0036] Preferably, as Figure 4As shown, the air leakage collection assembly 3 includes an intake fan 301 installed at the upper end of the tank body of the gas collection tank 1. The upper ventilation opening of the intake fan 301 is conductively connected to a rotating shaft sleeve 302, and an intake pipe 303 is rotatably connected inside the rotating shaft of the rotating shaft sleeve 302. The top end of the pipe of the intake pipe 303 is conductively connected to a diversion elbow 304, and the other end of the pipe of the diversion elbow 304 is conductively connected to a threaded pipe 305. A threaded sleeve 306 is screwed on the outer side of the pipe of the threaded pipe 305, and the bottom end of the pipe of the threaded sleeve 306 is conductively connected to a gas collection hood 307. The bottom ventilation opening of the intake fan 301 is conductively connected to the gas collection tank 1. By using the rotation of the rotating shaft sleeve and the intake pipe, the intake pipe can be driven to rotate horizontally along the rotating shaft of the rotating shaft sleeve, and the covering orientation of the gas collection hood can be flexibly adjusted in the left and right directions. By using the conductive combination of the intake pipe, the diversion elbow, the threaded pipe and the threaded sleeve, the gas leaked into the gas collection hood is negatively adsorbed, and the gas is sucked into the gas collection tank for detection, completing the detection of the gas concentration, judging whether the equipment has micro air leakage, and improving the safety of the equipment operation.

[0037] Preferably, as Figure 4 shown, a shaft seal adapted to the intake pipe 303 is provided inside the rotating shaft of the rotating shaft sleeve 302. The shaft seal can effectively prevent gas from leaking through the gap between the rotating shaft and the intake pipe, so as to ensure that the collected gas sample is accurate and reliable and will not be interfered by the external environment. Since this device is used to detect whether there is micro air leakage in the equipment, which usually occurs at a very slow speed and the leakage amount is very small, there are very high requirements for the airtightness of the collection device to ensure that there will be no additional gas leakage or external gas interference during the collection process.

[0038] Preferably, as Figure 2 shown, the infrared SF 6 sensor 5 is built-in with an alarm, and when SF 6 gas is detected, the alarm is automatically triggered. The infrared SF 6 sensor built-in with an alarm usually has high sensitivity and can detect very low SF 6 concentration, so as to detect the micro air leakage of the equipment. Other types of sensors such as electrochemical sensors can also be selected according to the actual situation. On this basis, the alarm signal can also be wirelessly transmitted from the sensor to the platform end or the mobile phone end, and the staff can discover the micro air leakage situation of the equipment in the first time.

[0039] Preferably, as Figure 2As shown, the movable isolation baffle 10 includes a fixed plate and a movable plate. A round hole is formed in the fixed plate, and the movable plate can movably cover this round hole to achieve sealing. The movement of the movable plate is controlled by rotating the knob 6 to open or close the round hole. Using a movable isolation baffle to isolate the upper and lower parts of the tank body is an effective solution for first isolating and detecting the collected gas. When SF 6 gas is detected, an alarm is given. The staff opens the set movable plate to make the upper and lower parts communicate, so that the leaked SF 6 gas enters the purification treatment part. After the treatment is completed, it is discharged. This design combines the two steps of detection and treatment to ensure that when SF 6 gas leaks, it can respond quickly and take measures.

[0040] Preferably, as Figure 3 shown, the atomizing spray assembly 4 includes a circulating water pump 401 installed at the bottom of the gas collection tank 1 in a conducting manner. The drainage port of the circulating water pump 401 is conductively connected to a circulating water pipe 402, and the pipe of the circulating water pipe 402 is conductively connected to a multi-component flowing water pipe 403 extending into the gas collection tank 1. The other end of the pipe of each group of the flowing water pipes 403 is conductively connected to a shunt ring pipe 404, and a plurality of atomizing nozzles 405 are arranged along the circumferential direction on the inner and outer sides of the pipe of the shunt ring pipe 404. After the gas is sucked into the gas collection tank, an appropriate amount of circulating water can be filled into the gas collection tank in advance, and then the circulating water pump is controlled to work to suck the water in the gas collection tank. Through the combination of the circulating water pipe and the flowing water pipe, it flows into the shunt ring pipe, and then under the atomizing spray of the atomizing nozzles, it is atomized and combined with the gas in the gas collection tank to settle, so as to perform atomizing adsorption and settlement treatment on the gas.

[0041] Preferably, as Figure 4 shown, the screw pipe length of the screw pipe 305 is the same as the sleeve length of the screw sleeve 306. By using the threaded connection of the screw pipe and the screw sleeve, the telescopic length of the screw sleeve on the screw pipe can be adjusted, and then the height and orientation of the gas collection hood can be flexibly adjusted and aligned.

[0042] When collecting gas near the suspected leakage part of the equipment, by using the left-right rotation adjustment and up-down height adjustment of the air leakage collection component, the gas collection orientation of its gas collection hood can be flexibly adjusted, so that it is in a suitable orientation for air leakage collection work. On the one hand, it has a flexible and variable alignment and installation performance, which can improve the installation convenience, and on the other hand, it has an accurate adaptation and corresponding performance, which can achieve efficient gas collection work.

[0043] Preferably, as Figure 4As shown, multiple groups of exhaust holes 309 are arranged circumferentially along the bottom of the pipe of the exhaust pipe 308. The gas is guided through the exhaust pipe to the lower half of the tank body for purification treatment. By arranging multiple groups of exhaust holes at the bottom of the exhaust pipe, the gas dispersion uniformity can be improved, facilitating atomized adsorption and sedimentation.

[0044] Preferably, as Figure 2 shown, the adsorption mesh plate 8 is a sponge filter screen, and the purification mesh plate 9 is an activated carbon filter screen. Due to its porous structure, the sponge filter screen can absorb a large amount of moisture, so it is very suitable for adsorption. During the process of gas flow, the sponge filter screen can remove moisture in the gas and keep the gas in a dry state; the activated carbon filter screen utilizes the adsorption performance of activated carbon to remove various pollutants in the gas, including harmful gases, odors, etc. First, the sponge filter screen adsorbs and dries the gas, removing the moisture in it, providing a dry environment for subsequent activated carbon adsorption. Then, the activated carbon filter screen further adsorbs and purifies harmful substances in the gas to ensure the purity of the gas. After purification treatment, the environmental-friendly gas is discharged.

[0045] SF 6 The detection method of the gas micro-leakage detection device performs the following steps:

[0046] (1) Place the gas collection hood 307 near the suspected leakage part of the equipment to collect gas, and start the intake fan to generate negative pressure in the gas collection hood 307. This negative pressure will suck in the gas leaked into the gas collection hood 307, making it flow towards the inlet of the fan. Through the conduction combination of the intake pipe 303, the diversion elbow 304, the threaded pipe 305 and the threaded sleeve 306, these gases are led to the gas collection tank 1;

[0047] (2) The gas accumulates in the upper half of the tank body of the gas collection tank 1. Use the infrared SF 6 sensor 5 to detect the concentration of SF 6 in the gas to determine whether there is a micro-leakage phenomenon. If SF 6 gas is detected, an alarm will be given;

[0048] (3) When the staff receives the alarm and determines that the equipment has a micro-leakage; purify and discharge the collected gas. Rotate the knob 6 to open the movable isolation baffle 10, and the gas flows downward to the lower half of the tank body. Start the atomizing spray. The gas after atomized sedimentation and adsorption is pushed by the driving fan to flow upward along the gas collection tank 1. During the upward process, it first passes through the adsorption mesh plate 8 for adsorption and drying, then passes through the purification mesh plate 9 for adsorption and purification, and finally opens the exhaust valve 2 to discharge.

[0049] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention. These changes involve related technologies well-known to those skilled in the art, and all of these fall within the protection scope of the patent of the present invention.
