Description

Technical Field

[0001] The utility model relates to the technical field of power monitoring of distribution networks, in particular to power loss monitoring equipment for distribution networks. Background Art

[0002] Distribution network power monitoring utilizes electrical and computer technology to monitor and analyze the status and operation of power systems. It can accurately detect and analyze the power quality of the power grid in real time, monitoring parameters such as voltage, current, and frequency, and quickly and accurately identifying and locating faults and losses. However, with the increasing demand for electricity, most important cables have been moved underground or to more hidden locations. When these cables become damaged, existing monitoring systems are unable to effectively detect and identify the location of the damage. Furthermore, prolonged damage can easily lead to additional power loss, and maintenance often requires power outages, significantly reducing production efficiency.

[0003] Most of the existing power monitoring devices in the distribution network only have monitoring functions and cannot provide temporary power supply when a fault occurs. Although they can detect power faults in the first time and allow staff to repair them in time to reduce additional losses, when the fault is large, it will still directly lead to power outages. A vacuum period will occur before the repair is completed, which will reduce the production efficiency of electrical equipment during this vacuum period.

[0004] Based on this, a distribution network power loss monitoring device is now provided to eliminate the drawbacks of the existing devices. Utility Model Content

[0028] In this embodiment, when a fault occurs, the spare cable 4 can be used quickly for emergency use, and the fault point can be quickly found through the sensor 3 and emergency insulation treatment can be performed through the insulation component.

[0029] In one embodiment, Figure 1 As shown, the sensor 3 is a partial discharge detection sensor. Partial discharge is a precursor to insulation damage. The use of a high-frequency type sensor such as a partial discharge detection sensor can detect these discharge signals.

[0030] In one embodiment, Figure 1 As shown, the insulating assembly includes a slide 10, which is slidably arranged on the outside of one end of the distribution cable 2. An insulating rubber ring 11 is fixedly connected to the inside of the slide 10. The inner side of the insulating rubber ring 11 is fitted with the outer side of the distribution cable 2. A connecting plate 13 is fixedly connected to one side of the slide 10, which slides to the fault position through the slide 10 and then is insulated through the insulating rubber ring 11.

[0031] In one embodiment, Figure 1 As shown, the insulation component and sensor 3 both slide on the surface of the distribution cable 2 through a mobile component to detect fault points and perform emergency insulation processing.

[0032] In one embodiment, Figure 1 As shown, the moving assembly includes a slider 8, which is fixedly connected to the adjacent end of the connecting plate 13 and the connecting rod 12 respectively. A threaded rod 9 is threadedly connected to the middle part of the slider 8. A motor 7 is provided at one end of the threaded rod 9 and is fixedly connected to the output end of the motor 7. When the motor 7 is started, it drives the slider 8 to slide on the threaded rod 9.

[0033] In one embodiment, Figure 1 As shown, the motor 7 is arranged on the fixed component.

[0034] In one embodiment, Figure 1 As shown, the fixing assembly includes a fixing frame 5 and a connecting column 14 , wherein one end of the fixing frame 5 and the connecting column 14 on the same side are respectively fixedly connected to one side of the adjacent current measuring device 1 , and the other end of the fixing frame 5 and the connecting column 14 are fixedly connected via a fixing rod 6 .

[0036] The above embodiment discloses a distribution network power loss monitoring device, in which a current meter 1 is set at both ends of the distribution cable 2 that is under key protection. The other output end of the current meter 1 is connected to a spare cable 4 as a spare cable, which is used as an emergency cable in the event of a fault. When a fault occurs, the motor 7 starts to drive the slider 8 to rotate, and then drives the sensor 3 to move on the surface of the distribution cable 2 to detect the fault point. The fault is randomly wrapped with an insulating rubber ring 11 to prevent leakage and other situations from increasing losses.
