Abstract
The utility model discloses a kind of secondary aviation socket interlock of high-tension switch cabinet.This interlock is in the time that circuit breaker moves from test position to service position, valve mechanism rotating shaft 1 is rotated and is driven rotating shaft connecting lever 2 to rotate, rotating shaft connecting lever 2 drives interlocking connecting lever 8 to rotate by bearing pin 3, connecting rod 4, interlocking connecting lever 8 drives interlock plate 5 to move by interlocking shaft 7 again, make its position of extracting of blocking aviation socket 6, thereby make it cannot extract the object that reaches interlocking.This interlock, fully uses transmission mechanics principle, and manufacture craft is simple, and cost is low, easy for installation, simple to operate, flexible.
Description
Technical field
The utility model relates to a kind of secondary aviation socket interlock of high-tension switch cabinet.
Background technology
Along with social development, electrical technology is also in continuous maturation, national grid is also more and more higher to the requirement of various equipment for power transmission and distribution, the scheme of the high voltage switchgear of existing many maturations is also in variation, general aviation socket and aviation socket are interlocked all at circuit breaker top, but also have individual program aviation socket can not be installed on circuit breaker top, can only be installed on circuit breaker side, therefore need to redesign a kind of secondary aviation socket interlock of high-tension switch cabinet.
Utility model content
The purpose of this utility model is to design a kind of secondary aviation socket interlock of high-tension switch cabinet.
The technical solution of the utility model is: a kind of secondary aviation socket interlock of high-tension switch cabinet, be characterised in that, rotating shaft connecting lever is installed in valve mechanism rotating shaft, rotating shaft connecting lever is connected with interlocking connecting lever by bearing pin, connecting rod, interlocking connecting lever and interlock plate are all fixed on interlocking shaft, interlocking shaft and secondary aviation socket are fixed on cabinet protective plate, and this has just formed whole interlock.In the time that circuit breaker moves from test position to service position, valve mechanism rotating shaft is rotated and is driven rotating shaft connecting lever to rotate, rotating shaft connecting lever drives interlocking connecting lever to rotate by bearing pin, connecting rod, and interlocking connecting lever drives interlock plate action by interlocking shaft again, thereby reaches the object of interlocking.
The secondary aviation socket interlock that the utility model provides, can prevent the electric accident causing because of secondary circuit power-off.Cost is low, easy for installation, simple to operate, flexible.
Brief description of the drawings
Fig. 1 is the side structure schematic diagram of the secondary aviation socket interlock embodiment of the utility model high-tension switch cabinet;
Fig. 2 is front face structural representation embodiment illustrated in fig. 1;
Fig. 3 is side face structural representation (interlocking position) embodiment illustrated in fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, valve mechanism rotating shaft 2, rotating shaft connecting lever 3, bearing pin 4, connecting rod 5, interlock plate 6, secondary aviation socket 7, interlocking shaft 8, interlocking connecting lever.
As shown in drawings, the secondary aviation socket interlock of the utility model high-tension switch cabinet, rotating shaft connecting lever 2 is installed in valve mechanism rotating shaft 1, rotating shaft connecting lever 2 is connected with interlocking connecting lever 8 by bearing pin 3, connecting rod 4, interlocking connecting lever 8 and interlock plate 5 are all fixed on interlocking shaft 7, interlocking shaft 7 and secondary aviation socket 6 are fixed on cabinet protective plate, and this has just formed whole interlock.
The interlock that the utility model provides, in the time that circuit breaker moves from test position to service position, valve mechanism rotating shaft 1 is rotated and is driven rotating shaft connecting lever 2 to rotate, rotating shaft connecting lever 2 drives interlocking connecting lever 8 to rotate by bearing pin 3, connecting rod 4, interlocking connecting lever 8 drives interlock plate 5 to move by interlocking shaft 7 again, make its position of extracting of blocking aviation socket 6, thereby make it cannot extract the object that reaches interlocking.
The interlock that the utility model provides, fully uses transmission mechanics principle, and manufacture craft is simple, and cost is low, easy for installation, simple to operate, flexible.
