Embodiment Construction
[0013] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0014] Such as Figure 1~6 As shown, it includes a driving cam 1, a first arc slot 1.1, a second arc slot 1.2, a third arc slot 1.3, a first pin 2, a second pin 3, a plate 4, and a third pin 5. Roller 6, screw 7, first cam 8, limit groove 8.1, notch 8.2, fixed shaft 9, shaft 10, second cam 11, protrusion 11.1, fourth pin 12, tension spring 13, fifth pin 14, The first torsion spring 15, the second torsion spring 16, the first mounting plate 17, the second mounting plate 18, the interlocking handle 19, the arc-shaped slot 20 and the like.
[0015] Such as Figure 1~6 As shown, a three-position switch switching and interlocking device of the present invention includes two first mounting plates 17 and second mounting plates 18 arranged in parallel with each other. The upper part and the lower part are respectively fixedly provided with a fixed shaft 9 and a first pin...

The invention belongs to the field of power transmission and distribution equipment and relates to an interlocking control device which is used for a switch of a solid insulation vacuum ring main unit vacuum breaker operation mechanism, in particular to a three-station switch switching and interlocking device. The three-station switch switching and interlocking control device can effectively prevent equipment faults caused by position errors of the operation mechanism. The three-station switch switching and interlocking control device comprises a first installation plate and a second installation plate which are parallel, a fixing shaft and a first pin shaft are fixedly arranged on the upper portion and the lower portion of the part between the first installation plate and the second installation plate respectively, a second pin shaft is fixedly arranged between the first installation plate and the second installation plate and corresponds to the position above the first pin shaft, two plates are arranged on the second pin shaft, two third pin shafts are fixedly arranged at the positions, close to the middle and the outer end of the part between the two plates respectively, and the third pin shaft located on the outer side is rotationally provided with a wheel. When the three-station switch switching and interlocking device works, the accuracy of control over different positions can be achieved, after reaching the positions, the three-station switch switching and interlocking device can be locked through a lock hole, and therefore three-station switch switching and the interlocking device cannot rotate.
Description
Technical field [0001] The invention belongs to the field of power transmission and distribution equipment, and relates to an interlocking control device used for the switch of the vacuum circuit breaker operating mechanism of a solid insulated vacuum ring network cabinet, which can effectively prevent the fault of the equipment caused by the incorrect position of the operating mechanism, specifically A three-station switch interlocking device. Background technique [0002] In the transmission and distribution, the ring main unit is the most widely used power equipment in substations and enterprises due to its small size and complete functions. It is the direction of development in the transmission and distribution. The ring main unit not only covers various power distribution requirements for power feeding, metering and communication, but also must be 1 / 3 smaller in size under the same conditions. To achieve safety and efficiency, and to implement various functions in a relative...
