Abstract
The invention discloses a GIS cable sleeve test window, which relates to the technical field of power transformation and comprises a box body, a grounding terminal, a transverse grounding bar and a vertical grounding bar. The grounding terminal is packaged in the box body, so that the grounding terminal has certain protection, and the safety is better. Furthermore, the grounding bar structure is designed to comprise a transverse grounding bar and a vertical grounding bar, and the transverse grounding bar is detachably connected with the grounding terminal, is also detachably connected with the vertical grounding bar, and is inserted into the box body in a drawable manner. During a test, the connection between each grounding terminal and the transverse grounding bar and the connection between the transverse grounding bar and the vertical grounding bar are disconnected, then the transverse grounding bar is drawn out, then the grounding terminal as a test phase is connected with a fault detection device, and the grounding terminal as a non-test phase is connected with the vertical grounding bar through an annealed copper wire. Non-test phase grounding is realized, and the test is simple and efficient.
Description
technical field [0001] The application relates to the field of power transformation technology, in particular to a GIS cable sleeve test window. Background technique [0002] With the continuous development of power distribution technology, cable-based transmission lines and GIS-based substation equipment are becoming more and more popular. T-connectors and cables are hard-connected in more and more forms in substations. [0003] In the case of hard connection between GIS and cable, if there is a permanent fault on the cable, it is necessary to untie the grounding terminal for insulation test and fault finding test. However, the current grounding terminal test process is time-consuming and labor-intensive, and the efficiency is low. Moreover, the current grounding terminal lacks certain protection, and the safety is also low. Contents of the invention [0004] In view of this, the purpose of this application is to provide a GIS cable sleeve test window to solve the probl...
