Detailed Description

The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.

As shown in fig. 1 to 3, the online arrester monitor according to the present embodiment includes a box 1 and a box door 2, wherein the box 1 is provided with the box door 2. The box door 2 is arranged on a fixed frame 3, and the fixed frame 3 is arranged on the box body 1. The fixed frame 3 comprises a frame body 4 and an accommodating groove 5, wherein the frame body 4 is provided with an inner side surface 6, the inner side surface 6 is formed by extending the frame body 4 towards the direction of the box body 1, and the inner side surface 6 of the frame body 4 surrounds to form the accommodating groove 5. The door 2 is arranged in the accommodating groove 5, the frame 4 comprises a first frame 41 and a second frame 42, the first frame 41 and the second frame 42 are arranged oppositely, and the first frame 41 and the second frame 42 are both provided with a hook part 7. The box 1 is equipped with connecting plate 11, and connecting plate 11 is extended to box 1 middle part by the top and the bottom of box 1 respectively and forms, and connecting plate 11 sets up perpendicularly, and hook portion 7 and connecting plate 11 joint. In the technical scheme, the box door 2 can be arranged on the fixed frame 3 by arranging the fixed frame 3, and the fixed frame 3 is clamped with the box body 1, so that the locking of screws is not needed, the installation is convenient, and the sealing performance is better; the box door 2 is connected with the fixed frame 3 through the rotating shaft 8, so that the box door can be conveniently opened or closed.
