The fixed seat of body upper end, described fixed claw is fixed in described fixed seat.
Its additional technical feature is:
Described fixed seat includes upper fixed seat and lower fixed seat, is provided between fixed seat and lower fixed seat
Fixed claw hole, is fixed by fastening bolt between fixed seat and lower fixed seat, the described fixation of described fixed claw insertion
Pawl in the hole；
Described support includes the first support fixing with described overvoltage protection body lower end and fixing with this first support
Second support, first support and second support are down " l " type, and described first support upper surface is provided with horizontal bar-shaped trough, institute
State overvoltage protection body lower end to be fixed in described horizontal bar-shaped trough；
First perpendicular bar-shaped trough and the second vertical bar are respectively arranged with described first support with described second support joint face
Shape groove, is provided with connecting bolt in the described first perpendicular bar-shaped trough and the second perpendicular bar-shaped trough.
Line type overvoltage protection device provided by the utility model compared with prior art, have the advantage that first,
Due to including overvoltage protection body, extinguishing arc mechanism and support, described extinguishing arc mechanism include circular arcing ring with fixed claw with
Positioned at the fixed seat of overvoltage protection body upper end, described fixed claw is fixed in described fixed seat, so, the face of arcing ring
Long-pending increase, the route of pipe line does not cause stitch seam leans out line because of external force such as wind-force, and circuit cannot deviate the scope of arcing ring, protected effect all the time
Good；Second, because described fixed seat includes upper fixed seat and lower fixed seat, setting between fixed seat and lower fixed seat
It is equipped with fixed claw hole, fixed by fastening bolt between fixed seat and lower fixed seat, described in described fixed claw insertion
Fixed claw in the hole, so, adjusts the position of arcing ring by adjusting position in fixed seat for the fixed claw, and range is wide；
Third, because described support includes the first support fixing with described overvoltage protection body lower end and fixing with this first support
Second support, first support and second support are down " l " type, and described first support upper surface is provided with horizontal bar-shaped trough, institute
State overvoltage protection body lower end to be fixed in described horizontal bar-shaped trough, so, by adjusting overvoltage protection body lower end in horizontal stripe shape
The position of groove, comes horizontal adjustment overvoltage protection body and arcing ring in the position of wire, range of application is wider；Fourth, due to
It is respectively arranged with the first perpendicular bar-shaped trough and the second perpendicular bar-shaped trough, described on described first support and described second support joint face
It is provided with connecting bolt in first perpendicular bar-shaped trough and the second perpendicular bar-shaped trough, so can be by adjusting connecting bolt in the first vertical bar
The position of shape groove and the second perpendicular bar-shaped trough adjusting the position between first support and second support, thus reaching vertical adjustment mistake
Pressure protection body and arcing ring are in the position of wire.
Brief description
Fig. 1 is the structural representation of this utility model line type overvoltage protection device；
Fig. 2 is the structural representation of first support；
Fig. 3 is the structural representation of second support.
Specific embodiment
Structure to this utility model line type overvoltage protection device and use with reference to the accompanying drawings and detailed description
Principle is described in further details.
As shown in figure 1, the structural representation of this utility model line type overvoltage protection device, this utility model line type mistake
Voltage protector includes overvoltage protection body 1, extinguishing arc mechanism 2 and support 3, and the circle that extinguishing arc mechanism 2 is included with fixed claw 4 disappears
Arc ring 5 and the fixed seat 6 being located at overvoltage protection body 1 upper end, fixed claw 4 is fixed in fixed seat 6, so, the face of arcing ring 5
