Abstract

The invention belongs to the technical field of power system connection protection, and relates to anintelligent bridging device for a screen top miniature bus. The intelligent bridging device comprises a shell, a panel is arranged on the shell, an ADC acquisition module and a CPU connected with the ADC acquisition module are arranged in the shell, the ADC acquisition module is connected with a plurality of filtering and amplifying modules, the filtering and amplifying modules are connected with a voltage transformer of a screen top miniature bus voltage loop so as to perform signal acquisition, the CPU is connected with a display module, and the display module comprises a touch display screen arranged on the shell. The device integrates the measuring, monitoring and connecting functions, simplifies the operation process, ensures the safe operation of a to-be-bridged bus, and improves the safety management and control quality of an operation site.

Description

technical field [0001] The invention belongs to the technical field of power system connection protection, and in particular relates to an intelligent jumper device for small busbars on a screen top. Background technique [0002] In the substation, most of the protective screens are connected by small busbars on the top of the screen. The small busbars on the top of the screen usually use copper rods with a diameter of 6mm or 8mm to provide power and secondary voltage for the relay protection device. [0003] Most of the small busbars on the top of the screen are laid through the whole connection. When a protective screen in the middle needs to be replaced, in order to ensure the normal operation of its adjacent operating equipment, relay protection personnel need to bridge the small busbar. The current working method is to bridge the temporary cable across the protective screen to be replaced, and then cut off the small bus bar on the top of the screen adjacent to the prote...
