Abstract
The utility model discloses an SF6 circuit breaker which comprises a control mechanism case, a pulling rod vertically arranged on the mechanism case, as well as an opening device and a closing device movably connected with the pulling rod respectively, wherein the opening device and the closing device are transversely mounted in the control mechanism case side by side, movably connected to the same crankarm respectively and connected with the pulling rod through the crankarm. By adopting the structure, the requirements of users for lowering the height of the product are fully met, no problems can be caused by mechanism installation and overhaul exiting, and the cost of the product is reduced; and in addition, because a novel spring control mechanism is horizontally arranged and the inner space is larger, an online monitoring device can be additionally arranged according to the requirements of the users so a to improve the competitiveness of the circuit breaker products on the market.
Description
Technical field
The utility model relates to a kind of primary cut-out, especially a kind of SF that is equipped with horizontal mechanism
6Circuit breaker.
Background technology
In the existing LW35-126 product, support height is unified to be 2020mm, the spring operating mechanism case distance from bottom ground of its outfit is 900mm, and according to some areas and exporting country to the requirement of 110kV circuit breaker setting height(from bottom), minimum support height need be reduced to 1400mm, the also corresponding reduction of mechanism case height overhead when support height reduces, simultaneously, because the branch of CT27-I spring operating mechanism, switching-in spring is not in same mechanism case, what switching-in spring was erect is installed on the mechanism case, tripping spring is fixed on the crossbeam inwall of support, and its complex structure is installed and withdrawed from maintenance to spring operating mechanism and causes very big difficulty.
The utility model content
The purpose of this utility model is: a kind of SF that is equipped with horizontal branch, switching-on mechanism is provided
6Primary cut-out to improve the height of mechanism case, is convenient to install and maintenance simultaneously.
The technical solution of the utility model is: a kind of SF
6Circuit breaker, comprise an operating mechanism case, the switching-off device and the closing device that hang down and to be located at the pull bar on this mechanism case and to flexibly connect with this pull bar respectively, described switching-off device and closing device laterally are installed in the described operating mechanism case side by side, and this switching-off device is movably connected in respectively on the same connecting lever and by this connecting lever with closing device and is connected described pull bar.
Above-mentioned connecting lever is the T shape of side, and the two ends of this T shape connecting lever cross bar are connected on switching-off device and the closing device by pivot pin, and the free end of its vertical rod is by the pivot pin cylinder lever connecting rod.
On-Line Monitor Device also is installed in the described mechanism case.
Adopt said structure, fully satisfied the requirement that the user reduces the product height, mechanism's product cost of installing and also can not throw into question, and reduced when withdrawing from maintenance, original mechanism is 4～50,000 yuans, improve the horizontal mechanism in back and then be 20,000 yuans; And because new spring operating mechanism adopts is horizontal layout, the inner space is bigger, can answer the user to require to increase on-Line Monitor Device, has improved the competitiveness of circuit breaker product on market.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, operating mechanism case 7 of fixed installation on the support, on operating mechanism case 7, hang down and be provided with a pull bar 5, switching-off device 2 and closing device 1 crosswise fixed side by side are installed in the operating mechanism case 7, switching-off device 2 and closing device 1 are connected the two ends of the cross bar of T shape connecting lever 3 respectively by pivot pin 4, the free end of T shape connecting lever vertical rod is connected on the pull bar 5 by pivot pin, also is provided with on-Line Monitor Device 6 in mechanism case 7.
