Specific implementation mode
A kind of drop-type arrester as shown in Figure 2-5, including insulator 1 and arrester main body 2, the insulator 1
Upper end is connect by conducting bracket 3 with the upper end of arrester main body 2.The lower end of insulator 1 is by falling part 4 and arrester main body
2 lower end connection, and the lower end of arrester main body 2 is provided with disconnector 5.Due to insulator 1, arrester main body 2, conducting bracket
3, it is the prior art well known to those skilled in the art to fall the basic connection structure between part 4, disconnector 5, herein no longer
It repeats.
The utility model it is maximum the difference is that, the top of the conducting bracket 3 is additionally provided with Anti-fall component, institute
It includes upright bar 6, leading block 7 and pulling rope 8 to state Anti-fall component.The upright bar 6 is located at the middle part of conducting bracket 3, described to lead
It is located at conducting bracket 3 close to one end of arrester main body 2 to pulley 7.One end of one end and helical spring 9 of the pulling rope 8
Connection, the other end of the helical spring 9 are connect with column.The other end of pulling rope 8 bypass leading block 7 after with arrester master
