C5-PFK rapid gas filling system and method

Abstract

The invention relates to the technical field of insulating gas equipment, in particular to a C5-PFK rapid gas filling system and method. The system comprises a C5-PFK gas filling device, a buffer gas storage device and a mixed gas storage device; a heating device is arranged at the exterior of the C5-PFK gas filling device, and the C5-PFK gas filling device is arranged in the heating device; the C5-PFK gas filling device comprises a gas filling bottle body, and the interior of the gas filling bottle body is sealed; and a gas filling pipe is arranged on the gas filling bottle body, and the gas filling pipe is connected to the mixed gas storage device through a switch valve. According to the C5-PFK gas filling device, a heating device is arranged at the exterior of the C5-PFK gas filling device, heat required for vaporization can be continuously provided when C5-PFK liquid is vaporized, and therefore it is guaranteed that in the continuous filling process of C5-PFK gas, the problem that the vaporization speed becomes lower and lower due to reduction of ambient temperature and consequently the concentration error of mixed gas is large is solved.

Description

technical field [0001] The invention belongs to the technical field of insulating gas equipment, and in particular relates to a C5-PFK rapid inflation system and an inflation method. Background technique [0002] C5-PFK is an insulating fluid. The GWP value of C5-PFK is only 1, which is far lower than 23500 of SF6. Its insulation performance is more than twice that of pure SF6. C5-PFK has excellent comprehensive characteristics such as environmental protection, insulation, and decomposition. , so that it has the potential to replace SF6 gas in various medium and low voltage gas-insulated equipment. [0003] However, the current research on C5-PFK mixed gas is still shallow, which greatly limits the application of mixed gas. The commonly used method for the configuration of C5-PFK mixed gas is the partial pressure method, that is, the partial pressure corresponding to each gas component is calculated according to the mixing ratio of the mixed gas and the pressure of the mixe...

Problems solved by technology

However, since C5-PFK usually exists in a liquid state, it will be vaporized into a gas and charged, and C5-PFK will continuously absorb the surrounding heat, resulting in the continuous decrease of the surrounding temperature as C5-PFK is continuously charged. , the vaporization speed is getting slower and slower, resulting in inaccurate pressure and large concentration error of the configured mixed gas.
