Problems solved by technology

In various previous studies, the effect of temperature on the partial discharge characteristics of basin-type insulators was only studied by changing the external environment temperature, but the change of external environment temperature is an overall change, which will cause the basin-type insulator epoxy insulation material, gas, electrode The same changes will occur in all, resulting in a large difference between the laboratory results and the on-site test results

Abstract

The invention discloses a partial discharge test system for a basin-type insulator epoxy insulating material, and the system comprises a test cavity which is internally provided with a ground electrode, and the ground electrode is internally provided with a heating device which is used for directly heating the ground electrode and indirectly heating the basin-type insulator epoxy insulating material and filling gas in the test cavity. A gradient temperature environment is formed by the ground electrode, the basin-type insulator epoxy insulating material and the filling gas; a high-voltage electrode is further arranged in the test cavity, one end of the high-voltage electrode is externally connected with a power source, the other end of the high-voltage electrode is connected with a basin-type insulator epoxy insulating material arranged on the ground electrode, and the high-voltage electrode and the ground electrode form an electrode assembly which is used for carrying out a partial discharge test on the basin-type insulator epoxy insulating material in a gradient temperature environment.

Description

technical field [0001] The present disclosure belongs to the technical field of electrical equipment testing, and in particular relates to a partial discharge testing system for a basin-type insulator epoxy insulating material. Background technique [0002] Gas-insulated metal-enclosed switchgear (GIS) is one of the most important equipments in the current power system, and its operational reliability is directly related to the security and stability of the power grid system. During the operation of the GIS, the conductor will flow through the operating current, and the contact between the conductor and the pot insulator will cause the temperature of the pot insulator epoxy insulation material itself to rise, which forms a gradient temperature environment with the electrode and the internal filling gas. The change of gradient temperature environment has a great influence on its partial discharge characteristics, which will lead to changes in the characteristics of its discha...
