Abstract

The invention discloses an equipotential field protection device, which comprises a potential protection module, a current sensor and an alarm module, wherein the potential protection module comprisestwo insulating protective layers, a conductive grid layer is clamped between the two insulating protective layers; the conductive grid layer is provided with at least two symmetrically arranged electrode leading-out ends, the electrode leading-out ends are communicated with a grounding wire to form a loop, the current sensor is arranged between the conductive grid layer and the electrode leading-out ends, and the current sensor is electrically connected with the alarm module. When a large current accident occurs, the step voltage is generated, the current at the electrode leading-out end is induced inside the conductive grid layer through a larger current and the current sensor, the current is converted into a voltage value, the alarm module is driven to generate early warning, and the formed step voltage is subjected to the early warning function, so that an operator can know the danger, guide the operator to pay attention as soon as possible, and concentrate on checking the potential safety hazard, thereby reducing the personal harm.

Description

technical field [0001] The present application relates to the technical field of leakage protection, in particular to an equipotential field protection device. Background technique [0002] When carrying out live work in substations or outdoors, it is usually necessary to use relevant testing equipment for live operation. For example, when carrying out partial discharge tests, it is necessary to connect the high-frequency CT with the grounding circuit while carrying out live inspections. It may occur that the operator may touch the housing of live equipment or adjacent equipment. [0003] If the detected equipment or adjacent equipment has failed, and the operator is unknown in advance, it is possible that the enclosure equipment will be charged. Even if the operator uses non-basic equipment for detection, the overcurrent signal generated by the fault current to the ground may cause the ground surface potential to rise, resulting in increased step voltage, which constitutes...
