Description

Technical Field

[0001] This utility model relates to the technical field of current traveling wave monitoring equipment, and in particular to a current traveling wave monitoring device. Background Technology

[0002] In the prior art, for grounding wires such as PT and CVT that are attached to a column or have a large diameter, the patent document with patent publication number CN208969139U discloses a traveling wave detection device. In this traveling wave detection device, a strategy is given to directly install the mounting base of the traveling wave detection device on the ground, that is, to achieve this by setting fixing holes on the left base and the right base.

[0003] However, in actual use, the left and right bases are often fastened together after the wires are threaded, and then a hammer or other tool is used to drive the pins that mate with the fixing holes into the ground, thus achieving the purpose of directly installing the traveling wave detection device's mounting base on the ground. However, when installing the traveling wave detection device on the ground, the structures above the left and right bases need to be fastened together before the pins are driven in. The process of driving in the pins will cause the entire traveling wave detection device to vibrate to some extent. The structures above the left and right bases that have been fastened together are prone to loosening due to this vibration, which is detrimental to the closure of the toroidal magnetic core to some extent, and consequently, may affect the reliability of the traveling wave detection device.

[0004] Therefore, this utility model provides a current traveling wave monitoring device to solve the above problems. Utility Model Content
