Abstract

The invention discloses a contact box and a switching device. The contact box comprises a cylindrical insulator and a sealing insulator connected with one end of the cylindrical insulator through a transition shoulder part. A static contact installation insert is arranged in the sealing insulator, and the outer edge of the static contact installation insert extends to the transition shoulder part. According to the contact box, the static contact installation insert and the sealing insulator are matched, so the thicknesses of all parts of the sealing insulator are basically equal, and the situation that a product cracks due to uneven thickness is avoided.

Description

technical field [0001] The invention belongs to the field of medium and high voltage switchgears, in particular to a contact box for 12kV complete switchgears. Background technique [0002] In the medium voltage switchgear, the use of the contact box has been very common, and the contact box mainly plays the role of insulation isolation and connection transition. [0003] At present, the box body material of the contact box is thermosetting epoxy resin material, which is formed by automatic pressure gel (APG) process. This process requires a lot of materials, the finished product is heavy, the production efficiency is low, and the product is easy to be damaged; the post-curing time of thermosetting epoxy resin material is long and the energy consumption is large, the production site is easy to be dirty and difficult to clean, and the waste materials cannot be recycled. It is difficult to degrade under natural conditions and causes great pollution to the natural environment....
