Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

please refer to fig. 1-4, in the embodiment of the present invention, a ring main unit with a protection device, including the outer cabinet body 1 of the ring main unit and the internally mounted electrical cabinet 2 of the electrical cabinet 2 bottom is provided with the pressure relief mechanism 3 the outer cabinet body 1 of the ring main unit bottom install with the supporting component 4 that the pressure relief mechanism 3 cooperates and uses the outer cabinet body 1 of the ring main unit and the electrical cabinet 2 interlayer are filled with the carbon dioxide utricule 101 the fusible piece 102 is installed in the upper right side of the electrical cabinet 2, the fusible piece 102 communicates with the interlayer, and the fusible piece 102 can fuse automatically when reaching a certain temperature.
