Description

Technical Field

[0001] The invention belongs to the technical field of ring main unit, and relates to a monitoring device for a ring main unit, in particular to a visual monitoring device for a ring main unit. Background Art

[0002] Ring main unit is mainly used in urban distribution network lines, residential houses, government units, office buildings, commercial buildings and other places to provide reliable power supply for various places. In case of line fault, it can effectively block the fault point to prevent large-scale power outages. Now with the development of distribution network automation, ring main unit has three remote functions, which can monitor line voltage, current, switch status in real time and has remote control function, which provides convenience and guarantee for load diversion, daily operation and maintenance, and fault isolation.

[0003] With the extensive use of ring main units and the increasing requirements of users for power supply reliability, the safe operation monitoring of ring main units has become increasingly important. During the use of ring main units, members of the public often pry open the doors of the ring main units and operate them privately, causing line tripping, power outages, and equipment burning. This poses a huge safety hazard to the operation and maintenance personnel's fault finding and on-site maintenance operations, seriously affecting the reliability of power supply. In addition, since many ring main units are installed in the suburbs and green belts, they are located in the blind spot of Skynet monitoring, making it difficult to obtain evidence and difficult to report the case and solve the case.

[0004] After searching, it is found that a monitoring device for an outdoor ring network cabinet is disclosed in Chinese patent documents [Application number: CN202010553122.9; Publication number: CN111653976A]. This monitoring device for an outdoor ring network cabinet includes a main support box, one side of the main support box is provided with an opening and closing groove, the inner side of the opening and closing groove is vertically clamped with a sealing door, one side of the sealing door is provided with a pull handle, one side of the sealing door is inlaid with a lock, the bottom surface of the main support box is vertically plugged with a support pole, the bottom end of the support pole is horizontally welded with a fixed bottom plate, the top surface of the main support box is horizontally provided with a sealing top plate, both sides of the sealing top plate are horizontally welded with isolation side plates, and the bottom surface of the sealing top plate is horizontally provided with an installation groove.

[0005] Although the ring main unit monitoring device disclosed in this patent adopts multi-angle monitoring to make the overall security better, the single monitoring can only take photos of the criminal gangs to collect evidence, and cannot fundamentally solve the hidden dangers of equipment anti-theft and anti-malicious operation. In addition, when the ring main unit door is pried open by social personnel to maliciously cut off the power and maliciously close the grounding switch to cause the line to trip and stop operating, the operation and maintenance personnel cannot be notified in time, which greatly prolongs the fault judgment and processing time of the repair personnel and reduces the power supply reliability.
