Description

Technical Field

[0001] The invention belongs to the technical field of sulfur hexafluoride circuit breaker detection, and more specifically, particularly relates to a device for detecting gas inside a GCB. Background Art

[0002] Sulfur hexafluoride circuit breaker is a circuit breaker that uses sulfur hexafluoride gas as arc extinguishing medium and insulating medium. Due to the excellent characteristics of this gas, the voltage and current parameters of a single break of this circuit breaker are much higher than those of compressed air circuit breakers and low-oil circuit breakers, and it does not require high gas pressure and a considerable number of series breaks. It is widely used in ultra-high voltage and large-capacity power systems. Regularly testing the gas purity in sulfur hexafluoride circuit breakers can promptly detect impurities or moisture in the gas, avoiding the impact of these impurities on the insulation and arc extinguishing performance of the equipment. By promptly dealing with these problems, the service life of the equipment can be extended, equipment failures and downtime can be reduced, and the reliability and availability of the equipment can be improved.

[0003] The GCB internal gas detection device currently used still has the following problems:

[0004] 1. Before gas detection, the excess air in the pipeline connecting the sulfur hexafluoride circuit breaker and the gas purity analyzer is generally discharged to improve the gas detection accuracy; when the pipeline is long and the exhaust time is short, there is still a small amount of air in the pipeline, which affects the gas detection accuracy; when the pipeline is short and the exhaust time is long, more sulfur hexafluoride gas will be discharged, which is inconvenient for the staff to accurately grasp the exhaust time;

[0005] 2. Usually there is a lack of automatic gas purification structure, which causes the discharged sulfur hexafluoride gas to diffuse directly into the air, which is not good for the health of workers and will pollute the environment;

[0006] 3. After the gas detection is completed, it is inconvenient to protect the gas purity analyzer, which causes the gas purity analyzer to be easily bumped during carrying and turnover, reducing its service life. Summary of the invention

[0020] 1. The U-shaped carrying handle of the present invention is convenient for the staff to carry and to detect sulfur hexafluoride circuit breakers in different areas. After the detection is completed, the staff places the gas purity analyzer body on the support frame B on the buffer frame A. On the one hand, the gas purity analyzer body is located between the buffer frame A and the support frame B to avoid collision of the gas purity analyzer body during carrying or transportation. On the other hand, when driving on bumpy roads, the four coil springs A play a buffering and protective role on the gas purity analyzer body, thereby increasing the service life of the gas purity analyzer body.

[0021] 2. When the present invention detects the gas inside the sulfur hexafluoride circuit breaker, the staff connects one end of the pipeline to the valve of the sulfur hexafluoride circuit breaker and connects the other end of the pipeline to the gas inlet head; after the pipeline is connected, when the staff opens the valve on the sulfur hexafluoride circuit breaker, the gas inside the sulfur hexafluoride circuit breaker enters the rectangular gas temporary storage cover through the pipeline, which collects the gas in the pipeline and also collects a small amount of sulfur hexafluoride discharged from the pipeline, thereby ensuring the purity of the sulfur hexafluoride gas in the pipeline and improving the detection accuracy of the sulfur hexafluoride gas;

[0022] In addition, when the rectangular movable plate presses the switch, the buzzer alarm works, which can automatically remind the staff that the air in the pipeline has been discharged, and at the same time a small amount of sulfur hexafluoride gas enters the rectangular gas temporary storage hood; it is convenient for the staff to appropriately adjust the position of the switch according to the length of the pipeline. When the length of the pipeline becomes longer, the switch is adjusted backward, and when the length of the pipeline becomes shorter, the switch is adjusted forward. Under the premise of ensuring that all the air in the pipeline is discharged, excessive sulfur hexafluoride gas is avoided from being discharged, thereby reducing the difficulty of subsequent purification.

[0023] 3. When the pipeline is connected to the gas inlet head of the present invention, the staff needs to rotate the movable blocking plate clockwise or counterclockwise to separate the movable blocking plate from the gas inlet head before connecting the pipeline to the gas inlet head; when the pipeline is in a connected state with the gas inlet head, the pipeline can support the movable blocking plate so that the movable blocking plate is always in an inclined state, and the movable blocking plate drives the gas purification housing A to rotate a certain angle, so that the circular purification through hole B is separated from the circular purification through hole A, and the gas in the rectangular gas temporary storage cover cannot be discharged through the circular purification through hole A;

[0024] In addition, when the air in the pipeline is discharged, the staff separates the pipeline from the gas inlet head and then connects the pipeline to the gas purity analyzer body. The movable blocking plate and the gas purification housing A automatically reset under the action of gravity, so that the circular purification through hole B is concentric with the circular purification through hole A. At this time, the gas in the rectangular gas temporary storage cover can contact the gas purification cotton through the circular purification through hole A and the circular purification through hole B, which plays a role in purifying the small amount of sulfur hexafluoride gas in the rectangular gas temporary storage cover.

[0025] In addition, the setting of two coil springs B enables the rectangular movable plate to push the gas in the rectangular gas temporary storage cover to be discharged quickly, thereby improving the gas purification efficiency. Under the premise of ensuring the detection accuracy of sulfur hexafluoride gas, it plays an automatic purification role for the small amount of excess sulfur hexafluoride gas discharged.

When the valve on the upper part is opened, the gas inside the sulfur hexafluoride circuit breaker enters the rectangular gas temporary storage cover 302 through the pipeline, which collects the gas in the pipeline. At the same time, it also collects the small amount of sulfur hexafluoride discharged from the pipeline, ensuring the purity of the sulfur hexafluoride gas in the pipeline and improving the detection accuracy of the sulfur hexafluoride gas; when the rectangular movable plate 303 presses the switch 404, the buzzer alarm 402 works, which can automatically remind the staff that the air in the pipeline has been discharged, and at the same time, a small amount of sulfur hexafluoride gas enters the rectangular gas temporary storage cover 302; when the pipeline is connected to the gas inlet head 306, The staff needs to rotate the movable blocking plate 502 clockwise or counterclockwise to separate the movable blocking plate 502 from the gas inlet head 306, and then the pipeline can be connected to the gas inlet head 306; when the pipeline is in a connected state with the gas inlet head 306, the pipeline can support the movable blocking plate 502, so that the movable blocking plate 502 is always in an inclined state, and the movable blocking plate 502 drives the gas purification shell A503 to rotate a certain angle, so that the circular purification through hole B5031 is separated from the circular purification through hole A3021, and the gas in the rectangular gas temporary storage cover 302 cannot be discharged through the circular purification through hole A3021;When the air in the pipeline is discharged, the staff separates the pipeline from the gas inlet head 306, and then connects the pipeline to the gas purity analyzer body 200. The movable blocking plate 502 and the gas purification shell A503 are automatically reset under the action of gravity, so that the circular purification through hole B5031 is concentric with the circular purification through hole A3021. At this time, the gas in the rectangular gas temporary storage cover 302 can contact the gas purification cotton 506 through the circular purification through hole A3021 and the circular purification through hole B5031, which purifies the small amount of sulfur hexafluoride gas in the rectangular gas temporary storage cover 302. The two coil springs B309 are set so that the rectangular movable plate 303 can push the gas in the rectangular gas temporary storage cover 302 to quickly discharge. The gas purity analyzer body 200 on the support frame B105 is placed on the buffer frame A103 after the detection is completed. On the one hand, the gas purity analyzer body 200 is located between the buffer frame A103 and the support frame B105 to avoid collision when the gas purity analyzer body 200 is carried or transported. On the other hand, when driving on bumpy roads, the four coil springs A104 play a buffering and protective role on the gas purity analyzer body 200, thereby increasing the service life of the gas purity analyzer body 200. ;
