Abstract

The invention provides a grounding box capable of switching grounding modes of a high-voltage cable and an electronic device. The grounding box comprises an insulating support, a protective layer overvoltage limiter, a grounding bar, a connecting bar, a standardized connecting module and a plurality of ports. Two ports form a group, the protective layer overvoltage limiter, the grounding bar, theconnecting bar and the ports are arranged on the insulating support, the standardized connecting module is used for connecting any group of ports, and switching of grounding modes is realized by controlling any group of ports to be connected or disconnected. According to the scheme, switching of grounding modes of a high-voltage cable grounding box is achieved by controlling connection or disconnection of any set of ports, the grounding mode switching modes are simplified, manpower, material resources and time are saved, a coaxial cable led out of a cable intermediate joint does not need to becut off, and switching of grounding modes of the high-voltage cable grounding box can be realized without connecting a fiber core and a shielding layer of a coaxial cable through a copper wire, removing an interphase connecting plate and connecting with an overvoltage limiter.

Description

technical field [0001] The present application relates to the field of high-voltage cable grounding, and in particular, relates to a grounding box and an electronic device capable of switching the high-voltage cable grounding mode. Background technique [0002] When performing certain types of high-voltage cable tests, such as high-voltage cable vibration tests and impedance spectrum tests, it is often necessary to restore the cross-connection system to a direct connection form. There are mainly two types of current technical solutions: 1) open the top cover of the grounding box, and restore the cross-connection box, the direct grounding box and the protective grounding box to the direct connection form respectively (that is, connect the core and shielding of the coaxial cable through copper wires). Layer, and remove the interphase connecting plate and connect with the overvoltage limiter); 2) Cut off the coaxial cable led out from the middle joint of the cable, and then use...
