The invention discloses a dry shielding grounding leakage current device, and the device comprises a bottom plate and a protector; one ends of the upper and lower side surfaces of the bottom plate are respectively provided with a group of power connection plates, and the upper end of the front side surface of the bottom plate on one side of each power connection plate is transversely provided with an information screen and a plurality of signal stroboscope lamps; an alarm is transversely arranged on one side of the power connection plate at the lower end of the front side surface of the bottom plate, an isolation cover is arranged at the upper end of the front side surface of the bottom plate between the alarm and the information screen, one end of the side face of the protector penetrates through the isolation cover and is provided with a main control handle, and a reclosing handle is arranged on the side face of the protector on one side of the main control handle; a plugboard is arranged at the lower end of the front side surface of one end, away from the reclosing handle, of the protector, and a smoke concentration sensor is arranged on the side surface of the protector on the outer side of the plugboard. The information screen is matched with the stroboscope lamp to effectively detect and display the power connection state of the leakage protector in real time, the reclosing handle can effectively reduce the utilization rate of the main control switch and guarantee the power connection safety performance, and the use effect is good.
Description
technical field [0001] The invention relates to the technical field of leakage protection, in particular to a dry shielding ground leakage current device. Background technique [0002] According to the working principle of the protector, it can be divided into three types: voltage type, current type and pulse type. The voltage-type protector is connected between the neutral point of the transformer and the earth. When an electric shock occurs, the neutral point shifts to generate a voltage to the ground, so that the protection action cuts off the power supply. However, because it protects the entire low-voltage network of the distribution transformer, It cannot be protected by grades, so the power failure range is large and the action is frequent, so it has been eliminated. The pulse type current protector is a sudden change in the phase and amplitude of the three-phase unbalanced leakage current when an electric shock occurs, which is used as an action signal, but it also ...
