Description

Technical Field

[0001] The present application relates to the technical field of fault locating devices, and in particular to a fault locating device for a power transmission and transformation line. Background Art

[0002] Transmission and transformation line fault location devices are important equipment used in power systems to quickly and accurately locate transmission line fault points. These devices monitor various parameters of the transmission lines in real time and use advanced sensing and communication technologies to accurately determine the fault points, providing a strong guarantee for the safe and stable operation of the power system.

[0003] At present, the relevant power transmission and transformation line fault locating devices lack a sealing structure and a shell structure that can be opened quickly. When used in rainy weather, rainwater can easily enter the inside of the device, causing damage to the internal components of the device. In addition, when the staff needs to maintain the device, the shell structure needs to be opened and tools need to be used to disassemble the structure, which is cumbersome and affects maintenance efficiency. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the present application provides a power transmission and transformation line fault location device.

[0005] The present application provides a power transmission and transformation line fault location device that adopts the following technical solution:

[0006] A fault locating device for a power transmission and transformation line comprises a fault locating mechanism, a lower protective shell and an upper protective shell, wherein the interior of the lower protective shell is fixedly connected to the fault locating mechanism, the outer side wall of the lower protective shell is fixedly connected to a rubber limit frame, one end of the lower protective shell is fixedly connected to a fixed block, both sides of the fixed block are fixedly connected to clamping blocks, the top of the lower protective shell is movably mounted with an upper protective shell via a hinge shaft, the outer side wall of the upper protective shell is fixedly connected to a rubber fixing frame, one end of the upper protective shell is fixedly connected to a connecting block, a positioning rod is movably mounted between the connecting block and the fixed block, both sides of the connecting block are fixedly connected to buckles, and the buckles are engaged with the clamping blocks.

[0007] The fault locating mechanism locates the fault of the transmission and transformation line. The lower protective shell and the upper protective shell cooperate to protect the fault locating mechanism. When the fault locating mechanism needs to be maintained, first loosen the positioning rod to separate the positioning rod from the fixing block, then pull the upper protective shell to disengage the buckle from the block. The upper protective shell drives the hinge shaft to rotate, so that the upper protective shell rotates open with the hinge shaft as the center, and the fault locating mechanism can be maintained. The rubber fixing frame and the rubber limit frame both have good sealing and waterproof effects. After closing the upper protective shell, the rubber fixing frame and the rubber limit frame are engaged to seal the gap between the upper protective shell and the lower protective shell.

[0008] Preferably, both sides of the bottom of the upper protective shell are fixedly connected with limiting rods, the inner side wall of the lower protective shell is fixedly connected with a positioning block, and the limiting rods are engaged with the positioning block.

[0009] When the upper protective shell is closed, the limit rod is embedded in the interior of the positioning block, which increases the friction between the upper protective shell and the lower protective shell and improves the stability of the connection between the upper protective shell and the lower protective shell.

[0010] Preferably, a screw hole is provided inside the fixing block, and the positioning rod is threadedly connected to the screw hole.

[0011] Screw the positioning rod into the screw hole so that the positioning rod contacts the fixing block, increasing the friction between the connecting block and the fixing block to fix the upper protective shell and the lower protective shell.

[0012] Preferably, the tops of the lower protective shells on both sides of the fault locating mechanism are fixedly connected with fixing rings, and both ends of the tops of the fixing rings are movably installed with fixing bolts.

[0013] Place the external substation line on the fixing ring, and then screw the fixing bolt into the inside of the fixing ring to fix the substation line using the fixing ring.

[0014] Preferably, reflective tapes are provided on the outer sides of the upper protective shells on both sides of the buckle, and the reflective tapes are made of organic resin material.

[0015] The reflective tape can reflect light, enhance the overall eye-catching effect of the device, and make it easier for staff to observe the location of the device.

[0016] In summary, this application has the following beneficial technical effects:

[0017] By setting the rubber fixing frame and the rubber limit frame, the gap between the upper protective shell and the lower protective shell can be sealed to prevent rainwater from entering the interior of the device and causing damage to the internal components due to moisture. By setting the fixing block, positioning rod and connecting block, the upper protective shell can be quickly opened to maintain the fault location mechanism without using tools to remove multiple fixing structures, which makes it more convenient for staff to perform maintenance operations on the fault location mechanism and improves maintenance efficiency.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The present application embodiment discloses a power transmission and transformation line fault location device. Figure 1-3 A power transmission and transformation line fault locating device includes a fault locating mechanism 3, a lower protective shell 5 and an upper protective shell 14. The fault locating mechanism 3 is fixedly connected to the interior of the lower protective shell 5. The fault locating mechanism 3 is a common power transmission and transformation line fault locating device in the technical field and is common knowledge. The power transmission and transformation line fault locating device mainly collects various parameter data along the line in real time through various sensors installed on the transmission line. These data are transmitted to the monitoring center through wireless communication technology, and the data are analyzed and processed by special software to finally determine the location and nature of the fault.

[0024] A rubber limit frame 4 is fixedly connected to the outer wall of the lower protective shell 5, and a rubber fixing frame 1 is fixedly connected to the outer wall of the upper protective shell 14. The rubber fixing frame 1 and the rubber limit frame 4 are both made of sealed silicone rubber material and have good sealing and waterproof effects. After closing the upper protective shell 14, the rubber fixing frame 1 and the rubber limit frame 4 are engaged to seal the gap between the upper protective shell 14 and the lower protective shell 5, thereby preventing rainwater from entering the interior of the device through the gap between the upper protective shell 14 and the lower protective shell 5 in rainy weather, causing the fault locating mechanism 3 to be damaged by moisture.

[0025] One end of the lower protective shell 5 is fixedly connected to a fixed block 6, and both sides of the fixed block 6 are fixedly connected to a card block 7. The top of the lower protective shell 5 is movably installed with an upper protective shell 14 through a hinge shaft 15. One end of the upper protective shell 14 is fixedly connected to a connecting block 12. A positioning rod 11 is movably installed between the connecting block 12 and the fixed block 6. Both sides of the connecting block 12 are fixedly connected to a buckle 10, and the buckle 10 is engaged with the card block 7. When the staff closes the upper protective shell 14, the buckle 10 is engaged with the card block 7, which increases the friction between the upper protective shell 14 and the lower protective shell 5. The friction is increased to improve the stability of the connection between the upper protective shell 14 and the lower protective shell 5, and then the positioning rod 11 is screwed into the interior of the fixing block 6 to further increase the friction between the upper protective shell 14 and the lower protective shell 5, so that the upper protective shell 14 and the lower protective shell 5 are fixed. When the staff needs to maintain the fault locating mechanism 3, they first loosen the positioning rod 11 to separate it from the fixing block 6, and then pull the upper protective shell 14 to separate the buckle 10 from the block 7. The upper protective shell 14 drives the hinge shaft 15 to rotate open, and the fault locating mechanism 3 can be maintained.

[0026] Reference Figure 1 , both sides of the bottom of the upper protective shell 14 are fixedly connected to the limit rod 2, and the inner wall of the lower protective shell 5 is fixedly connected to the positioning block 8, and the limit rod 2 is engaged with the positioning block 8. When the upper protective shell 14 is closed, the limit rod 2 is embedded in the inside of the positioning block 8, which increases the friction between the upper protective shell 14 and the lower protective shell 5, and improves the stability of the connection between the upper protective shell 14 and the lower protective shell 5.

[0027] Reference Figure 1 The top of the lower protective shell 5 on both sides of the fault locating mechanism 3 is fixedly connected with a fixing ring 9, and both ends of the top of the fixing ring 9 are movably installed with fixing bolts 901. The external substation line is placed on the fixing ring 9, and then the fixing bolts 901 are screwed into the inside of the fixing ring 9 to fix the substation line using the fixing ring 9.

[0028] The implementation principle of a power transmission and transformation line fault locating device in an embodiment of the present application is as follows: a fault locating mechanism 3 locates a power transmission and transformation line fault, and the lower protective shell 5 and the upper protective shell 14 cooperate to protect the fault locating mechanism 3. When the fault locating mechanism 3 needs to be maintained, first loosen the positioning rod 11 to separate the positioning rod 11 from the fixing block 6, and then pull the upper protective shell 14 to disengage the buckle 10 from the block 7. The upper protective shell 14 drives the hinge shaft 15 to rotate, so that the upper protective shell 14 rotates open with the hinge shaft 15 as the center, and the fault locating mechanism 3 can be maintained. The rubber fixing frame 1 and the rubber limiting frame 4 both have good sealing and waterproof effects. After closing the upper protective shell 14, the rubber fixing frame 1 and the rubber limiting frame 4 are engaged to seal the gap between the upper protective shell 14 and the lower protective shell 5 to prevent rainwater from entering the interior of the device and prevent the internal components of the device from being damaged by moisture.
