GW8-40.5I-72.5I-126I-GW8˘ńSeries Perfection Improved Neutral Point Disconnect Switch
GW8˘ńseries perfection improved neutral point disconnect switch is single-pole directly- swing type three-phase AC 50Hz outdoor HV equipment used as connection wire for neutral point of opening and closing transformer under no-load condition.
There are different specifications for GW8˘ńseries.
1.Divided into following type according to operation mechanism
1). CS17˘ô perfection improved munual mechanism;
2). Equiped with CJ6G perfection improved electric mechanism;
2. According to environment pollution grade, it is divided into grade ˘ň, ˘ó,˘ô.
GW8˘ńseries perfection improved neutral point disconnect switch is single-pole and single-column structure consists of base,surpport insulator, galvanic circuit,operation mechanism etc. Switch blade is placed at the lower end of insulator and fixed contact at the upper end of surpport insulator. When closing, space in between switch blade and fixed contact right over will become insulating break in verical direction. When closing action, switch blade make rotating motion in the verical plane until join the fixed contact and mesh correctly.
Neutral point disconnect switch can be equiped with CJ5,CJ6,CJ2-XG perfection improved electric mechanism as well as CS17˘ô perfection improved manual mechanism. The manual mechanism also can be equiped with new type DSW electromagnetic lock.
