High reliability of the operating mechanism 

- Separate design of the main circuit from the 

operating mechanism. 

- Adopt the toggle link method. 

- Improved the reliability of electric circuit. 

- Adopt the rapid auto-reclosing method as a 

standard option. (O-0.3sec.-CO-3min.-CO) 

High interrupting performance 

- Make short of the interrupting time. (3cycles) 

- Increase the rated short-circuit withstand 

characteristics. (1sec. to 3sec.) 

Great operational safety 

- Reinforce the insulation in the conduct, by 

adopting the molded housing in each phase. 

- Built in the device making the contacts open first 

when draw in and out. 

- Adopt the tulip-shape connection between the 

cradle and the VCB.

Structure 

The internal components of a typical Vacuum Interrupter are shown in Figure1. 

LG Vacuum Interrupter consists of a ceramic insulator, two end plates, arc shield, 

bellows, a movable and fixed electrode, and contact set. 

The ambient gas pressure within the evacuated tube is 

approximately 10-6 torr.

Figure 3. AC arcing and interruption phenomena in vacuum. 

In the closed position, normal current flows through 

the interrupter. When a fault occurs and interruption 

is required, the contacts are quickly separated. 

The arc drawn between the surfaces of contacts is 

rapidly moved around the slotted contact surface 

by self induced magnetic effects, preventing gross 

contact erosion and the formation of hot spot on 

the surface. 

The arc burns in an ionized metal vapor, which 

condenses on the surrounding metal shield. At 

current zero the arc extinguishes and vapor 

production ceases. 

The metal vapor plasma is very rapidly dispersed, 

cooled, recombined, and deionized, and the metal 

vapor products are quickly condensed so that the 

contacts withstand the transient recovery voltage.
