【Specific embodiment】
The utility model is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1, the utility model includes isolation-grounding interlocking device and ground connection-isolation and cable chamber door interlocking dress
Put two parts.Isolation-grounding interlocking device includes the first connecting lever 1 being installed on interrupter main shaft, under the first connecting lever 1
Portion is connected with right interlock plate 3, right interlock plate 3 by the guiding of the support 2 installed on switch cubicle right plate and it is spacing under carry out
Lower motion.Ground connection-isolation and interlocking device for cable vault door include the second connecting lever 8 on earthed switch power transmission shaft, second
The top of connecting lever 8 is connected with Left-wing Federation's jam plate 4, and Left-wing Federation's jam plate 4 is by the guiding of support 2 installed on switch cubicle left plate and spacing
Under moved up and down, cable chamber door inner side limiting plate 9 is installed.
The course of work of the present utility model and principle：
The active blocking device of set of switches is arranged on switch cubicle interior plate.
