Abstract

The invention relates to the transformer station protection technology, in particular to an intelligent bus grounding warning device and solves the problem that single-phase earth fault fails to be declared easily in the conventional transformer station single-phase earth fault alarming method. The intelligent bus grounding warning device comprises a case part and a warning part; the case part comprises a case body; the warning part comprises a CPU, an operation button, a display screen, a three-phase interface, a fiber interface and an RJ 45 interface, wherein the CPU is mounted in the inner chamber of the case body; both the operation button and the display screen are mounted on the front side wall of the case body in a penetrating manner; the three-phase interface, the fiber interface and the RJ 45 interface are mounted on the rear side wall of the case body in a penetrating manner; the signal output terminal of the operation button is connected with the signal input terminal of the CPU (2); the signal input terminal of the display screen is connected with the signal output terminal of the CPU. The invention is applicable to transformer station protection.

Description

technical field [0001] The invention relates to substation protection technology, in particular to an intelligent busbar grounding alarm device. Background technique [0002] Substations with ungrounded neutral systems do not trip their lines after a single-phase-to-earth fault, but keep operating normally. However, at this time, the ground phase voltage of the substation has approached zero, and the other two-phase voltages of the substation have approached the line voltage, which will damage the insulation of the primary equipment of the substation, and even burn the primary equipment of the substation. Therefore, in order to ensure the safe operation of the substation, it is necessary to timely alarm the single-phase ground fault of the substation. The existing substation single-phase ground fault alarm method mainly judges whether a single-phase ground fault occurs in the substation by judging whether the open delta voltage of the substation is greater than a limit valu...
