Problems solved by technology

However, due to the dispersion of the sampling parts, it caused great inconvenience to the test personnel. Furthermore, due to the small amount of gas, once the sampling failed, it was impossible to analyze and judge.

Embodiment 1

[0027] Embodiment 1: as Figure 1 to Figure 2 As shown, a gas sampler includes a sleeve 4 and a piston rod 5 matched with it. The front end of the sleeve 4 is provided with a first bronchus 3, and the first bronchus 3 communicates with an air guide tube 13, which is far away from the sleeve. One end of 4 is provided with a rubber head 1, and the air duct 13 is connected with a second bronchus 10, and the end of the second bronchus 10 away from the air duct 13 is provided with a combustion head 12, and the first bronchus 3 is provided with a first valve 2, and the second bronchus 10 is provided with a second valve 11.

[0028] It also includes a housing, and a cavity matching the sleeve 4 and the piston rod 5 is arranged in the housing.

[0029] The sleeve 4 and the piston rod 5 are located in the housing, and the front end of the first bronchus 3 passes through the housing and communicates with the air duct 13 .

[0030] The casing includes an upper casing 6 and a lower casi...

Abstract

The invention provides a gas sample collector.The gas sample collector is characterized by comprising a sleeve and a piston rod matched with the sleeve, a first branch gas pipe is arranged at the front end of the sleeve and communicated with a gas guiding pipe, a rubber head is arranged at the end, far away from the sleeve, of the gas guiding pipe, the gas guiding pipe is communicated with a second branch gas pipe, a burning head is arranged at the end, far away from the gas guiding pipe, of the second branch gas pipe, a first valve is arranged on the first branch gas pipe, and a second valve is arranged on the second branch gas pipe.By site testing, all technical indexes of the gas sample collector conform to design requirements, sampling tests of gas are achieved, using is convenient, and sampling results are accurate.

Description

technical field [0001] The invention relates to the field of electric equipment testing, in particular to a gas sampler. Background technique [0002] When the main transformer operates with heavy gas, due to the high internal temperature of the transformer, it is easy to cause faults, such as coil grounding, insulation breakdown, etc. The accompanying faults usually cause cracking of oil, etc., and then produce incombustible gas and flammable gas according to the severity of the fault. At this time, test personnel are required to conduct gas sampling and analysis. The most convenient way is to extract the gas and ignite it to see if the gas is flammable. If it is flammable, it means that there is a high temperature failure inside. [0003] For gas sample collection, the traditional method is to use a syringe and a rubber hose to connect to the sampling nozzle. However, due to the dispersion of the sampling parts, it is very inconvenient for the test personnel. Furthermore...
