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 displace

Example Embodiment

[0047] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0048] The device for detecting the compatibility of solid-liquid materials and gas production characteristics provided by the embodiments of the present invention, such as Figure 1 to 7 As shown, it includes: container 1, measuring tube 2, push rod 3, exhaust hole 4, sealing partition plate 5, measuring hole 11, rubber plug 31, three-way switch 41, air gap 51, inlet hole 52, sealing rubber ring 6. The container 1 is a sphere with a flat bottom and is provided with a measuring hole 11 and an exhaust hole 4 respectively. A three-way switch 41 is installed in the exhaust hole 4; a measuring tube 2 is installed in the measuring hole 11, and the inner diameter of the measuring tube 2 is larger than the measuring hole 11. After the measuring tube 2 is bonded to the container 1, the sealing rubber ring 6 is installed. The measuring tube 2 ...

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 ...
