Device and method for detecting compatibility and gas generation features of solid material and liquid material

Abstract

The invention provides a device and method for detecting compatibility and gas generation features of a solid material and a liquid material. The improved device is characterized by comprising a container which is integrally formed, and is provided with a measuring hole and an exhaust hole, wherein a measuring tube is arranged in the measuring hole, and a push rod is arranged in the measuring tube in the axis direction of the measuring tube. The insulating solid material is placed into the container, the container is filled with insulating oil, insulating oil is injected into the measuring tube, and therefore the compatibility and the gas generation features of the solid material and the liquid material can be measured at the corresponding environment temperature and in the corresponding holding time. Compared with the prior art, the device and method for detecting the compatibility and the gas generation features of the solid material and the liquid material have good gas tightness, and a test of the compatibility and the gas generation features of the solid material and the liquid material can be accomplished at one time.

Description

technical field [0001] The invention relates to a device for detecting solid-liquid materials, in particular to a device and method for detecting the compatibility and gas production characteristics of solid-liquid materials. Background technique [0002] In recent years, with the accelerating pace of power development, the operating voltage level of the power grid system has been continuously improved, and the network scale has also been continuously expanded. At present, power grid construction has become the main direction of power construction. By 2020, a strong smart grid will be fully built, and the goal of building a world-class power grid will be initially realized. [0003] Whether different materials of power equipment in operation can maintain stability is the basis for safe operation of power equipment. In recent years, there have been some defects due to the continuous increase of characteristic gases such as hydrogen in power equipment, and even formed family ...

Problems solved by technology

[0006] However, two tests were carried out with reference to ASTM_D_3455-2002 and ASTM_D_7150-2005, which not only caused a lot of unnecessary duplication of work, but also had the following defects

[0007] 1. DGA is not included in the 5 indicators evaluated by ASTM_D_3455-2002. If the method and container are unchanged and the DGA test is added, the test results of the gas production characteristics will be inaccurate, because the continuous or intermittent nitrogen protection during the test will cause It has a certain displacement effect on the generated characteristic gas; and the general three-necked flask cannot guarantee good air tightness, because the volume of insulating oil will increase with the increase of temperature

[0008] 2. ASTM_D_7150-2005 does not consider the influence of power equipment materials. Only about 40ml is accurately reserved in a 100ml syringe. The proportional amount of material will be difficult to process because it is too small, and the material inside the syringe will damage the gas of the syringe due to wear. Tightness
