Abstract

The invention discloses a power distribution cabinet, and an electric leakage warning apparatus and an electric leakage warning method therefor. The electric leakage warning apparatus comprises a detection element used for detecting the electrified state of the cabinet body, a control element used for sending out a signal when the cabinet body is electrified, and a warning device used for sending out a warning signal when a cabinet body electrified signal is received from the control element; the detection element is in signal connection with the control element; and the control element is in signal connection with the warning device. In the operating process, the control element receives the cabinet body electrified state signal detected by the detection element, and judges whether the cabinet body is electrified or not; when the cabinet body is electrified, the control element sends out the cabinet body electrified signal to the warning device, and the warning device sends out the warning signal; therefore, the power distribution cabinet equipped with the electric leakage warning apparatus can send out the warning signal when the cabinet body is electrified, so that power-off maintenance can be carried out conveniently in time; and consequently, potential safety hazards can be eliminated, and the safety performance of the power distribution cabinet can be improved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an electric leakage alarm device for a power distribution cabinet. The present invention also relates to a power distribution cabinet including the above leakage alarm device, and a leakage alarm method based on the leakage alarm device. Background technique [0002] In modern production and life, electrical components are widely used. Power distribution cabinets can integrate complex electrical equipment and circuits, and distribute power energy. effect. In the actual use process, the power distribution cabinet may leak electricity. At this time, the cabinet body of the power distribution cabinet is charged, threatening the safety of relevant staff, and there is a huge potential safety hazard. [0003] Therefore, providing a leakage alarm device for a power distribution cabinet, in order to send an alarm signal when the cabinet body is charged, so as to timely cut...
