[0001] The present invention relates to the technical field of power distribution networks, and in particular to a fault locating device for a smart power distribution network. Background Art

[0002] The distribution network is a network system used to distribute electric energy in the power system. As an important part of the power system, the distribution network is responsible for receiving electric energy from the transmission network or regional power plants. As the last mile of the power system, the distribution network plays a vital role in ensuring the quality and reliability of power supply. Facing the future, the modernization and intelligent construction of the distribution network will be the key. This is not only related to the economy and reliability of the power system, but also an important part of promoting the overall sustainable development of society. The importance of the distribution network in modern society is self-evident. It is one of the basic public facilities to ensure the normal operation of cities and villages. An efficient and reliable distribution system can not only improve energy efficiency, but also greatly support economic development and social stability.

[0003] During the maintenance and use of distribution network-related equipment, short circuits of electronic components in the equipment may occur, requiring staff to accurately inspect and quickly repair them.

[0004] A Chinese patent has been published (Announcement No. CN114137359A), which discloses a fault information collection device for locating faults in a DC distribution network, including a fault information collection chassis, an external collection box and a data transmission device. A driving motor is arranged inside the fault information collection chassis, and one end of the driving motor is rotatably connected to a running screw. An external collection box is arranged on one side of the fault information collection chassis, and a Bluetooth signal device is arranged on the external collection box. An analysis device is arranged at one end of the Bluetooth signal device, and a conduction line is arranged between the Bluetooth signal device and the analysis device. A fault inspection module is arranged at the input end of the Bluetooth signal device, and a fault locating module is arranged at the output end of the fault inspection module. The data collection module arranged at the output end of the fault locating module can collect data from the fault area of ​​the DC distribution network, and then the distribution network terminal control module is used to control the distribution network to prevent the fault from affecting other network areas.

[0041] See also Figure 3 , 4As shown in Figure 11, the disconnect mechanism 301 includes a moving rod 19, a moving rod 19, and a moving rod 19 that is slidably connected to the inside of the second mounting plate 8 and the third mounting plate 12. The moving rod 19 is respectively fixedly connected to the second mounting plate 8 and the third mounting plate 12 with two groups of first elastic springs 18, and the two groups of first elastic springs 18 are both sleeved on the outer surface of the moving rod 19. The upper end surface of the moving rod 19 is fixedly connected to an abutment block 23, and the abutment block 23 is adapted to a corresponding group of second elastic telescopic rods 22. The bottom end of the chassis 1 is fixedly connected to an abutment plug 51, and the abutment plug 51 is slidably connected to the inside. Two groups of movable columns 52 are connected, and the two groups of abutment plugs 51 are symmetrically distributed. A third elastic spring 53 is fixedly connected between the movable columns 52 and the abutment plugs 51. The two groups of third elastic springs 53 are both sleeved on the outer surface of the movable columns 52. A socket 37 is fixedly connected between the two groups of movable columns 52.

A power plug 15 for connecting a power source is fixedly connected to the bottom of the socket 37, and the upper end of the abutment plug 51 is fixedly connected to the power module 11.

[0042] The working principle of the present invention is: when in use, the power plug 15 is plugged into the power supply, at this time, the current will pass through the power plug 15 through the socket 37 and the abutment plug 51 into the power module 11, and then pass from the power module 11 between the two groups of first installation disks 24 corresponding to the fuse 25, and then the first installation disks 24 respectively supply power to the signal transmitter 6 and the service terminal 5, and the voltage detector 9 can be used to detect the voltage of the current passing through the fuse 25, and the data will be displayed on the control panel 4 in real time for the staff to detect and observe;

[0043] When one of the service terminal 5 or the signal transmitter 6 has an unstable voltage and a high voltage short circuit, the fuse 25 will blow under high voltage. At this time, the first elastic telescopic rod 17 inside the rectangular box 20 will drive the corresponding second mounting disc 33 to abut against the first abutment plate 21. At this time, the first abutment plate 21 will drive the second elastic telescopic rod 22 to contract. During the contraction of the second elastic telescopic rod 22, it will abut against the fourth elastic telescopic rod 38. The fourth elastic telescopic rod 38 drives the first latching tooth to disengage from the third latching tooth 39 on the rotating disk 40. At this time, since the force storage torsion spring 47 inside the second mounting box 46 is not restricted, the force storage torsion spring 47 is released. The spring 47 will release the stored force, and the stored force torsion spring 47 drives the knocking stick 43 to rotate by rotating the disc 45, and the knocking stick 43 knocks the bell 41 by abutting the ball 44. It is worth noting that the service terminal 5 and the signal transmitter 6 are respectively fixedly connected to the power module 11 through the connecting mechanism 101, so when any set of fuses 25 are blown at high voltage, according to the above working principle, the fuse 25 will trigger an alarm when it is blown, which is convenient for the staff to accurately confirm which of the service terminal 5 and the signal transmitter 6 is short-circuited (when the service terminal 5 and the signal transmitter 6 fail, the staff can quickly and conspicuously identify them);

[0044] Since when one of the service terminal 5 or the signal transmitter 6 is short-circuited, the second elastic telescopic rod 22 contracts and the abutment block 23 drives the moving rod 19 to move downward, and the moving rod 19 drives the socket 37 to be pressed downward through the second abutment plate 54, so that the socket 37 is disconnected from the abutment plug 51, thereby achieving the effect of disconnecting the power supply, thereby preventing the service terminal 5 and the signal transmitter 6 inside the chassis 1 from being damaged again and causing a safety accident;

[0045] When the fuse 25 needs to be replaced, it is only necessary to pull the connecting rod 35 through the pull handle 26 first, and the connecting rod 35 drives the abutment ring 31 and the meshing gear 29 to move upward through the third elastic telescopic rod 27, so that the meshing gear 29 between the abutment ring 31 and the second mounting disc 33 is disengaged, which is convenient for the staff to disengage the meshing gear 29 between the abutment ring 31 and the second mounting disc 33. At this time, the second mounting disc 33 is rotated, and the second mounting disc 33 drives the second latching tooth 28 to rotate through the gear ring 32, and the second latching tooth 28 drives the corresponding sliding gear The eight sliding racks 34 move, and at this time, the eight sliding racks 34 spread outward. After the damaged fuse 25 is taken out, a new fuse 25 is placed between the eight sliding racks 34, and then the second mounting disc 33 is rotated in the opposite direction, and the gear ring 32 is driven to rotate by the second mounting disc 33, and the gear ring 32 then drives the corresponding second latching teeth 28 to rotate, and the second latching teeth 28 drive the sliding rack 34 to reset. At this time, the eight sliding racks 34 gather together to fix and limit the new fuse 25, and the installation is completed.
