Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, an external gap arrester comprises an arrester body, wherein the arrester body comprises a shell 1 made of an insulating material outside, a resistor 2 is arranged inside the shell, and an upper incoming line 3 and a lower outgoing line 4 are respectively connected with the resistor; install outer clearance outside the arrester body, outer clearance be two electrodes that the distance is nearer, these two electrodes are first electrode 5 and second electrode 6 respectively, the second electrode inlet wire of connecting the arrester body, characterized by: the device also comprises a frame 7, wherein the frame is provided with an upper mounting plate 71 and a lower mounting plate 72, the upper mounting plate and the lower mounting plate are connected through a support 73, the first electrode 5 is mounted on the upper mounting plate, the second electrode 6 is mounted on the lower mounting plate, the part (with a gap) with the closer distance between the first electrode and the second electrode is arranged between the upper mounting plate and the lower mounting plate, and the frame is connected with the shell 1.
The utility model discloses set up like this, can be that first electrode 5 and second electrode 6 install on the frame, the rigidity, clearance between first electrode and the second electrode is adjusted by personnel, and the frame mounting also is very easy installation on the casing, can realize the utility model aims at.
The first electrode may be mounted on the upper mounting plate by passing it through the upper mounting plate and the second electrode may be mounted by passing it through the lower mounting plate, although the upper and lower mounting plates 71, 72 have apertures through the electrodes.
Further, the upper mounting plate, the lower mounting plate and the support member are made of an integrated epoxy resin material.
Furthermore, the frame and the shell are made of integrated insulating materials, so that the installation is more convenient.
Further, a hollow structure 74 is arranged between the upper mounting plate and the lower mounting plate in the front and back direction.
This has the advantage that the first electrode 5 and the second electrode 6 do not damage the frame when they break down.
Further, the frame 7 and the housing 1 are screwed together.
Further, a side surface between the upper mounting plate and the lower mounting plate is a hollowed-out structure 74. That is, the upper mounting plate, the lower mounting plate and the support member form a chamber, and the first electrode 5 and the second electrode 6 are in the chamber, so that the exposure of the first electrode 5 and the second electrode is reduced.
