Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment 1:
Shown in Fig. 1-4, a kind of high-voltage central-positioned switch cubicle electric grounding knife-switch, including base plate 10, it is arranged on described base plate 10
On multiple insulators 2, described insulator 2 upper end is fixedly connected with quiet top board 4, and described quiet top board 4 lower surface is fixedly connected with
Static contact 3, described base plate 10 is also equipped with rotor 21, and described rotor 21 is provided with moving contact 6, and described moving contact 6 is with rotor
21 swing up and down for the center of circle and coincide with described static contact 3 time moving contact 6 swings to upper extreme position and contact, on described rotor 21
Being also associated with driven gear 13, described driven gear 13 is driven by the driving means 12 being arranged on base plate 10.
Operation principle:
After being energized driving means 12, driving means 12 drives driven gear 13 to rotate, thus rotor driven 21 rotates, due to
Moving contact 6 is connected with rotor 21, and therefore, when rotor 21 rotates, moving contact 6 does same angular velocity together with rotor 21 and rotates, from
And realize the swing of moving contact 6；When driving means 12 rotates forward, moving contact 6 is swung up contacting with static contact 3, works as driving means
During 12 reversion, moving contact 6 swung downward separates with static contact 3, thus reaches to control moving contact 6 and stationary contact by driving means 12
3 purposes being connected and disconnected from, i.e. realize substituting existing manual hand manipulation by Electronic control, and meanwhile, its effect is more preferable,
Not by distance limit, safety is higher.
