Technical field
The utility model relates to high voltage isolator, relates in particular to a kind of disconnecting link interlock of the high voltage isolator with the ground connection disconnecting link.
Background technology
In the industrial production, many electric equipments all can use high voltage isolator.Especially in stopping sending the frequent electric equipment of electricity, as ladle furnace etc., the application of isolating switch is particularly important.For guaranteeing the person, device security and prevention large area blackout, the operator lock of high voltage isolator and the separating brake of ground connection disconnecting link, close a floodgate and must be undertaken by certain regulation, promptly operate lock and ground connection disconnecting link must keep closing in one minute one.The operator lock of traditional high voltage isolator and the separating brake of ground connection disconnecting link overlap independently operating mechanism by two usually with the control of closing a floodgate to be finished.Yet misoperation very easily takes place in this control mode, causes security incident.For this reason, various interlocks are devised, and meet accident avoiding.Yet the common complex structure of existing interlock is difficult to practical application.And in order to be complementary with different electric equipment, the model of high voltage isolator is numerous, and existing interlock can not be general between the high voltage isolator of different model, causes cost to increase.Therefore, demand urgently providing a kind of high voltage isolator disconnecting link interlock to overcome above-mentioned defective.
The utility model content
The technical problems to be solved in the utility model is to provide the major-minor disconnecting link interlock of a kind of simple in structure, highly versatile and stable and reliable operation high voltage isolator.
In order to solve the problems of the technologies described above, the utility model provides a kind of high voltage isolator disconnecting link interlock, comprise first rocking bar that is fixed in the operator lock rotating shaft, be fixed on second rocking bar in the rotating shaft of ground connection disconnecting link and the connecting rod of adjustable in length, described connecting rod two ends are hinged with described first rocking bar and second rocking bar respectively.
Compared with prior art, the operator lock rotating shaft of high voltage isolator of the present utility model and the rotating shaft of ground connection lock are provided with interlocking gear, it is simple in structure, compact, simple operation, make the operator lock and the mutual counteragent of ground connection disconnecting link of high voltage isolator, can effectively avoid the mistake of high voltage isolator disconnecting link to divide mistake to close, thereby ensure life safety; In addition because the fixed angle of first rocking bar and second rocking bar is variable, and the connecting rod adjustable in length of this interlocking gear, thereby go for the high voltage isolator of multiple model, highly versatile, and then can reduce cost.
Preferably, described connecting rod comprises a full flight screw and two connectors, and two described connectors are hinged with described first rocking bar and described second rocking bar respectively, and have the internal thread that is complementary with described connecting rod on it.By the length that the mode of internal and external threads is regulated connecting rod, simple and convenient, and low cost of manufacture.
Alternatively, described connecting rod comprises positive and negative screwed connection sleeve and a pair of screw mandrel, and two described screw mandrels are hinged with described first rocking bar and described second rocking bar respectively.
By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.

Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, the similar elements label is represented similar elements in the accompanying drawing.As mentioned above, the utility model provide a kind of simple in structure, can be for the general high voltage isolator disconnecting link interlock of high voltage isolator of different model.
Elaborate the technical scheme of the utility model embodiment below in conjunction with accompanying drawing.Shown in Fig. 1 a-1b, the high voltage isolator disconnecting link interlock of present embodiment comprises first rocking bar 1, second rocking bar 2 and the connecting rod 3 that connects described first rocking bar 1 and second rocking bar 2.Described connecting rod 3 comprises that a connecting rod 4 and 5, two described connectors 5 of two connectors are hinged with described first rocking bar 1 and described second rocking bar 2 respectively, is connected between the described connector 5 to described connecting rod 4 scalable adjustings.Shown in Fig. 1 b, the connecting rod 4 of present embodiment is a full flight screw, is preferably full silk Metallic rod, and connector 5 is a U-shaped spare, the 5a of its two ear is hinged by bearing pin 6 and described first rocking bar 1 or second rocking bar 2, is provided with the internal thread that is complementary with described full flight screw in the 5b of its bottom.By threaded engagement, promptly the length of scalable connecting rod is simple and convenient.
Preferably, each parts of the high voltage isolator disconnecting link interlock of present embodiment are metalwork, and fabrication and processing is simple, and structure is firm, and is not fragile.The minimum range that will guarantee this interlock and high pressure disconnecting link during installation meets high-voltage safety apart from standard, and this knows for those skilled in the art, omits at this and describes in detail.
Fig. 2 a has shown the high voltage isolator of the high voltage isolator disconnecting link interlock that present embodiment is installed.Shown in Fig. 2 a, aforementioned first rocking bar 1 is installed in the operator lock rotating shaft 21 of this high voltage isolator, and aforementioned second rocking bar 2 is installed in the ground connection disconnecting link rotating shaft 22 of high voltage isolator.First rocking bar 1 can be fixed in the operator lock rotating shaft 21 by the perforation set screw, and described second rocking bar 2 also can be fixed in the ground connection disconnecting link rotating shaft 22 by the perforation set screw.By adjusting between first rocking bar 1 and the operator lock rotating shaft 21 and the angle between second rocking bar 2 and the ground connection disconnecting link rotating shaft 22, change simultaneously the length of connecting rod 3 according to actual needs, can guarantee that the ground connection disconnecting link fully disconnects (combined floodgate) when high pressure operator lock fully closes a floodgate (separating brake).The high voltage isolator disconnecting link interlock of present embodiment is promptly applicable to the high voltage isolator of various different models.As shown in the figure, the high voltage isolator disconnecting link interlock of present embodiment is positioned at the not homonymy of this high voltage isolator with the operating mechanism 9 that is fixed in the operator lock rotating shaft 21, so that install.
