Description

Technical Field

[0001] The utility model relates to the technical field of circuit systems, in particular to a portable ground fault locator. Background Art

[0002] The ground fault locator is suitable for overhead lines in grounding systems. After a line is shut down due to a single-phase ground fault, the ground fault locator can be used to accurately locate the connection point. The ground fault locator is a portable device that can locate faults in multiple lines. The whole set of equipment consists of a transmitter, a sensor, a receiver and accessories. After the faulty line is shut down, the transmitter applies an ultra-low frequency high-voltage signal to the line to reproduce the fault. The sensor is hung on the line with an insulating rod along the line to detect the signal, and the data is transmitted to the receiver on the ground wirelessly. The receiver displays the measurement results.

[0003] At present, the existing ground fault locator has a transmitter located inside a box, and a handle is provided on the outer surface of the transmitter box. When the ground fault locator is needed, the transmitter box can only be extracted by the handle. Since the transmitter box is heavy, a lot of manpower is required when carrying it, which increases the workload of the operator and does not have a good portable effect. Moreover, the entire ground fault locator is exposed to the outside. Since there is no structure to protect it, the ground fault locator is easily damaged by external substances, resulting in inconvenience in use. Therefore, it is urgent to design a portable ground fault locator to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model forms a portable ground fault locator by arranging a folding tripod structure, a connecting rod and a handle frame. The folding tripod structure is unfolded and closed by using the handle frame, so that the entire ground fault locator body is pulled to move with the universal wheel, so that the entire ground fault locator body has a portable effect, and the entire ground fault locator body does not need to be manually carried, which saves manpower and reduces the workload of operators.

[0015] The utility model provides a flip assembly so that when the folding tripod structure is unfolded and closed, the protective cover can be synchronously driven to close and unfold. On the one hand, the protective cover can protect the ground fault locator body when not in use to avoid the problem that the ground fault locator body is exposed to the outside and is easily damaged by foreign substances. On the other hand, the protective cover can be detached from the ground fault locator body when in use, which is convenient for use. BRIEF DESCRIPTION OF THE DRAWINGS
