Abstract

The invention provides an insulation device which comprises a shell (10) and an electric conducting element arranged in the shell (10). The electric conducting element comprises contacts which comprise a wire inlet contact (21) and a wire outlet contact (22), the wire inlet contact (21) and the wire outlet contact (22) are electrically connected through a switch mechanism which comprises a conducting rod (30) and a power piece (40), the conducting rod (30) is arranged in the shell (10) and can move in the linear direction, the conducting rod (30) comprises a first position where the wire inlet contact (21) and the wire outlet contact (22) are communicated and a second position where electric connection of the wire inlet contact (21) and the wire outlet contact (22) is interrupted, and the power piece (40) drives the conducting rod (30) to move in the linear direction. By means of the technical scheme, the problem that in the prior art, an insulation device is too large in size in order to meet the use requirement of an insulation knife is effectively solved.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to an insulating device. Background technique [0002] The existing widely used insulated fully sealed switchgear generally includes an isolation part, a load switch part, and an inlet and outlet bushing part. Among them, most of the isolation is knife-type, including static contacts and isolation knives. Each time the switch is opened or closed, the isolation knife needs to be rotated to separate or contact the isolation knife with the static contact. [0003] The above isolation part has high requirements on the degree of contact between the isolation blade and the contact, and the degree of contact between the isolation blade and the contact is related to the temperature rise and dynamic and thermal stability of the entire device. Especially as the voltage level increases, a great pressure is needed to ensure that the isolation knife is in full contact with the contact. [00...
