Description

Technical Field

[0001] This utility model belongs to the field of power maintenance technology, and in particular relates to a single-phase grounding fault control device. Background Technology

[0002] In power systems, single-phase grounding faults are a common and impactful type of fault in distribution networks. Traditional distribution networks often use ungrounded neutral points or grounded via arc suppression coils. Once a single-phase grounding fault occurs, the fault characteristics are often not obvious, making it difficult to quickly and accurately locate the fault point. This not only leads to an expansion of the power outage area and a longer outage time, affecting users' normal power consumption, but may also trigger intermittent arc grounding overvoltages, threatening the safety of power equipment. Therefore, it is urgent to develop an efficient and reliable single-phase grounding fault management device to improve fault detection and location capabilities, ensure the safe and stable operation of the power system, and reduce economic losses.

[0003] However, existing single-phase ground fault control devices are not convenient to install the detectors in the corresponding positions during use. It requires staff to spend a lot of time installing them, which is not only time-consuming and laborious, but also prolongs the overall testing time. Moreover, the cumbersome installation method is prone to installation errors. Utility Model Content

Spring 218 is fitted on the outer wall of 7. The left side of spring 218 is fixedly connected to slider 216, and the right side of spring 218 is fixedly connected to slider 215. The gripper assembly 22 includes a hinged hinge rod 221. A hinge rod 222 is hinged on the inner wall of the connecting block 211. The side of hinge rod 222 near hinge rod 221 is hinged to hinge rod 221. A gripper 223 is hinged on the side of hinge rod 222 away from the connecting block 211. A hinge rod 224 is hinged on the inner wall of gripper 223. The side of hinge rod 224 away from gripper 223 is hinged to the connecting block 211. By setting the connecting mechanism, the detector of the device can be installed in the corresponding position more simply and conveniently. It is not only easy to operate, but also easy to adjust and can adapt to different situations.

[0030] The storage mechanism 3 includes a detector 301 fixedly connected to the inner wall of the box 1. Handles 302 are fixedly connected to the right side of the box 1 and the top of the box cover 101. A partition 303 is hinged to the inner wall of the box cover 101. A slider 304 is slidably connected to the inner wall of the box cover 101. Two sliding rods 305 are fixedly connected to the inner wall of the box cover 101. Springs 306 are sleeved on the outer walls of the two sliding rods 305.

By setting up the storage mechanism, it is more convenient to move the device. The device can be easily stored and taken away without the need for staff to spend a lot of time on its placement and transfer.

[0031] A specific application of this embodiment is as follows: First, move the device to the appropriate position, then open the cover 101. Next, push the slider 304 into the cover 101. At this time, the slider 304 will cause the spring 306 to undergo elastic deformation and generate elastic force. Then, open the partition 303, remove the connecting mechanism 2, and insert the plug 213 into the detector 301. The detector 301 is a TLHG-7010, and its working principle is based on wave propagation theory. Waves propagating on overhead lines will reflect when they encounter open or short circuits, forming standing waves. Changing the wave frequency can cause the wave trough to appear at the signal injection point. Given the wave velocity of the overhead line, the distance between the fault point and the measurement point can be calculated using a formula by detecting the standing wave frequency. The plug 213 is a matching connection device for the detector 301. Place the device on the power equipment to be tested. Then pull the slider 215 to apply pressure to the spring 218, causing it to deform elastically and generate elastic force. When the slider 216 is pulled away from the ratchet 214, the slider 215 can be pushed, causing the gripper 223 to move through the hinge rod 221 under the action of the hinge rod 3 224 and the hinge rod 222, thereby separating the two grippers 223. Then place it on the power equipment to be tested. Then the slider 216 can be released, and the slider 215 can be pulled back. Then the device is fixed on the power equipment by the gripper assembly 22. Under the action of the buckle assembly 21, the device will not fall off. After the test is completed, the connecting mechanism 2 can be removed and put back into the box cover 101. Then the partition 303 is closed first, and then the box cover 101 is closed. The device can be transferred by the handle 302.
