Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection, in particular to a lightning protection device for urban power facilities. Background Art

[0002] With the development of the national economy, the voltage level and scale of the power system have developed and expanded rapidly. As a result, the overhead transmission lines of the power system are widely distributed and are easily attacked by lightning. Substations and buildings are also often attacked by lightning. Due to the randomness and short-term nature of lightning, it is particularly important to accurately locate the time and parameter characteristics of the lightning current. The parameter characteristics of lightning current are of great significance for lightning protection countermeasures, improving the performance of lightning protection facilities, evaluating the protection range of lightning protection facilities for various equipment, substations and buildings, and analyzing lightning damage accidents. Lightning arresters are usually used for lightning protection of urban power facilities. Lightning arresters are located outdoors and installed on the top of urban power facilities. Therefore, lightning arresters are easily affected by wind and vibration. Bolt installation is usually used for lightning arrester installation. However, due to the bolt installation method, the bolts are prone to deflection and slippage when vibrating, resulting in loose installation, which affects the security of the installation. To this end, we propose a lightning protection device for urban power facilities. Utility Model Content

A bolt 4 is provided between the mounting base 2 and the fixing base 3, and the bolt 4 is threadedly connected to the mounting base 2 and the fixing base 3. At the same time, when the bolt 4 is screwed and installed, it can drive the annular plug-in plate 6 to rotate so that it can be plugged into the mounting base 2, and then the bolt 4 can be connected while the annular plug-in plate 6 is connected, thereby making the connection more secure.

[0022] See also Figures 1 to 6 The fixed seat 3 is movably sleeved with multiple gear ring seats 8 corresponding to the bolts 4. The gear ring seat 8 can rotate at a fixed position on the fixed seat 3, and the number of its annular plug-in plates 6 corresponds to the bolts 4.
