Description

Mounting bracket for soft Rogowski coil lightning current sensor

technical field

The utility model relates to a mounting device for a lightning current sensor, in particular to a mounting bracket for a lightning current sensor based on a soft Rogowski coil. the

Background technique

The measurement of lightning current parameters is of great significance to discuss lightning protection countermeasures and improve the performance of lightning protection facilities. The lightning current sensor based on soft Rogowski coils for lightning current parameter measurement has been gradually applied due to its significant advantages. Its skeleton is made of soft insulating material, which is small and light. In addition to considering the stability of the sensor during installation, in order to ensure the measurement accuracy, there are also certain requirements for its circularity. At the same time, in order to prevent lightning from forming a counterattack on the coil, the sensor needs to be connected with the tower or the installation base. Certain air gaps. the

Detailed ways

The content of the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. the

1 and 2, the mounting bracket of the soft Rogowski coil lightning current sensor of the present invention is composed of a base 1, a long screw 2, a nut II3, a ring 4, a clip 5, a bolt 6 and a nut I7. the

The base 1 is a rectangular flat plate, four flat clip holes are respectively provided at the four corners of the base 1 , and four bolt holes are uniformly arranged in the middle of the base 1 . the

The clip 5 is composed of two matching clips, the clips are L-shaped, one of the clips passes through the clip hole provided on the base 1, and the two clips are connected by bolts 6 and nuts 17. The two clips and the bolts 6 and nuts 17 connecting them together form a fixed structure, through which the entire mounting bracket is fixed on the tower during use. Bolt 6 and nut 17 are made of metal material such as stainless steel. the

A long bolt 2 and a nut II3 jointly form a connection structure, and the long bolt 2 passes through the bolt holes provided on the base 1 and the ring 4 and is fixed by the nut II3. A total of 4 connection structures are made of insulating materials such as nylon, which can connect the ring 4 and the base 1 together, and keep a certain space gap between them to prevent lightning from striking back the sensor coil. the

The ring 4 is made of epoxy resin material, and is provided with other 4 bolt holes corresponding to the 4 bolt holes on the base. the

The mounting bracket also includes a lightning current drain pin, which is fixed on the base 1 (not shown in the figure). the

When in use, the soft Rogowski coil lightning current sensor can be placed flat on the ring 4, initially fixed with cable ties to ensure the circularity of the coil, and then fixed with waterproof tape in a circle, and it can also be waterproof to ensure the normal operation of the sensor and service life, and the lightning current drain pin can be directly welded to the center of the base 1 . the

The utility model can conveniently and reliably complete the installation of the soft Rogowski coil sensor, can meet the normal working conditions and requirements of the soft Rogowski coil lightning current sensor, and is also convenient for later maintenance. the
