Technical Field
The utility model relates to an arrester technical field especially relates to a high flux capacity 35kV circuit arrester.
Background
The insulation level of a 35kV power transmission line is low, and equipment damage (such as insulator explosion, string falling, wire damage and the like) caused by lightning strike sometimes occurs. The power supply distance of the 35kV line in a remote mountain area is long, the complexity of the terrain is almost the same as that of a high-grade line, in order to avoid forest fire and casualties caused by wire breakage, the 35kV line adopts a protection strategy of single-phase grounding, namely tripping (reclosing does not directly trip three phases), and the lightning trip of the single-power-supply 35kV line means power supply interruption. The line arrester is successfully applied to a high-voltage-class power grid, but the common model 35kV line arrester (the 2ms square wave capacity of a resistor disc is 400A) is frequently exploded in practical use.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a high flux capacity 35kV circuit arrester to solve the problem that above-mentioned prior art exists, frequently take place thunderbolt tripping operation and arrester explosion phenomenon behind the 35kV circuit arrester of 35kV circuit section installation.
In order to achieve the above object, the utility model provides a following scheme:
the utility model provides a high-flux capacity 35kV line arrester, be in including upper fixed plate, bottom plate and a plurality of setting the upper fixed plate with arrester between the bottom plate, every the top of arrester all with the upper fixed plate is connected, every the bottom of arrester is even the bottom plate is connected.
