Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0025] It should be noted that when an element is referred to as being “fixed on”, “disposed on” or “installed on” another element, it may be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be an intervening element at the same time; the specific way that one element is fixedly connected to another element can be realized through existing technologies, and will not be discussed here. To repeat it agai...

Description

technical field [0001] The invention relates to the technical field of material performance detection, in particular to an experimental device for measuring the lightning impulse withstand voltage characteristics of an insulating liquid. Background technique [0002] In the high-voltage power industry, the insulation properties of insulating liquid materials used in power equipment directly determine the safety and reliability of power equipment and power grid operation. Therefore, it is particularly necessary to regularly test the electrical properties of related insulating liquid materials. The electrical properties of liquid materials under a DC electric field are important indicators for evaluating the dielectric strength of insulating materials. The current commonly used detection method is to control the discharge gap between the electrode pairs, and then through the breakdown discharge and measure the relevant parameters of the insulating liquid, and then conduct scie...
