Description

Technical Field

[0001] The invention relates to the technical field of live-line working in distribution network, in particular to a monitoring and early warning device for live-line working in distribution network. Background Art

[0002] Live working on distribution networks is an effective means to improve power supply reliability and user satisfaction with electricity consumption. It is currently a conventional distribution network maintenance operation method. During normal live working on distribution networks, the line equipment at the work point is in a normal energized operating state, and the operators perform standardized operations in accordance with the safety operating procedures to ensure the personal safety of the operators. At this time, if a sudden fault causes a single-phase or multi-phase power outage in the line equipment at the work point, due to the possibility of power restoration and forced power transmission without notifying the on-site operators, the operators are exposed to possible operational overvoltage and abnormal voltage increase risks. According to a power-off alarm device for live working on distribution networks with application number CN210534977U, it has an insulating blanket clamp with a power-off alarm function formed by setting the insulating blanket clamp and the power-off alarm device together. Rotating the handle can drive the two clamps to rotate to control the opening or closing of the clamping cavity. While clamping and fixing the insulating blanket and other shielding tools used in the live working process, the collection device set on the power-off alarm device is used to collect The signal acquisition device of the line equipment electric signal collects the electric signal. When it is detected that the operating line equipment has no power, the control module controls the alarm device to work, which can immediately prompt the operator to stop working, evacuate personnel, and immediately contact the on-duty control personnel or operation and maintenance personnel to avoid the safety hazards brought to the operators by the possible strong power transmission operation causing overvoltage or the abnormal increase of the non-grounded phase voltage caused by single-phase grounding; by setting the power-off alarm device on the insulating blanket clip, the line equipment can be monitored without directly contacting the line equipment without damaging the outer insulation layer of the insulating shielding equipment and the line equipment, making the active monitoring work safer, more reliable and more convenient; and more convenient to carry. However, the rocker switch is exposed on the outer surface of the cover, which makes the switch operation more convenient, but when working, the staff may accidentally turn off the rocker switch, causing the device to shut down, making the device unable to perform early warning monitoring, and causing accidents.
