Description
Technical field
This utility model relates to a kind of switchgear, particularly relates to a kind of GIS combination electric appliance disconnecting switch interlock.
Background technology
In power industry, GIS is by primary equipment in addition to transformator in a transformer station, including chopper, disconnecting switch, earthed switch, voltage transformer, current transformer, spark gap, bus, cable termination, inlet-outlet sleeve etc., optimized design is organically combined into an entirety.The advantage of GIS is that floor space is little, and reliability is high, and high safety, maintenance workload is the least.The closing a floodgate and open a sluice gate the electrical control that mostly uses of disconnecting switch and earthed switch in traditional GIS, by electrically carrying out the chain operation of disconnecting switch and earthed switch, only the most operable in the case of having electricity, the scope of application is less.
Summary of the invention
The purpose of this utility model is to provide the GIS combination electric appliance disconnecting switch interlock of a kind of reliable in action of interlocking.
For achieving the above object, technical solution of the present utility model is:
This utility model is a kind of GIS combination electric appliance disconnecting switch interlock, including disconnecting switch, earthed switch, disconnecting switch transmission crank arm, disconnecting switch kinematic link, interlock plate, rotational pin, fixed plate, earthed switch transmission crank arm, earthed switch kinematic link；Described earthed switch is arranged on the lower section of disconnecting switch, the inner of disconnecting switch transmission crank arm is connected with the disconnecting switch power transmission shaft outer end in disconnecting switch, the outer end of disconnecting switch transmission crank arm is hinged with the middle part of disconnecting switch kinematic link, and the outer end of disconnecting switch kinematic link is slipped with the upper end of interlock plate；The bottom bending of described interlock plate, form a kink, interlock plate bending place is hinged in fixed plate by rotational pin, the outer end of interlock plate kink has leaning or departs from two kinds of earthed switch transmission crank arm top duty, the inner of earthed switch transmission crank arm is connected with the power transmission shaft outer end of earthed switch, the outer end of earthed switch transmission crank arm is hinged with earthed switch kinematic link, and fixed plate is arranged on earthed switch.
The top of described interlock plate is provided with elongated slot, and the outer end of disconnecting switch kinematic link is slipped in the elongated slot on the top of interlock plate by trundle.
Described disconnecting switch transmission crank arm has three, and the outer end of three disconnecting switch transmission crank arm is all hinged with the middle part of disconnecting switch kinematic link.
Described earthed switch transmission crank arm has three, and the outer end of three earthed switch transmission crank arm is all hinged with the middle part of earthed switch kinematic link.
After using such scheme, owing to this utility model includes disconnecting switch transmission crank arm, disconnecting switch kinematic link, trundle, interlock plate, rotational pin, fixed plate, earthed switch transmission crank arm, earthed switch kinematic link, disconnecting switch is by switch transmission crank arm, disconnecting switch kinematic link, interlock plate, fixed plate, earthed switch transmission crank arm, the parts such as earthed switch kinematic link form linkage with earthed switch, the outer end of interlock plate kink has leaning or departs from two kinds of earthed switch transmission crank arm top duty, ensure that the reliable of disconnecting switch and earthed switch interlocking action.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention
As shown in Figure 1-Figure 3, this utility model is a kind of GIS combination electric appliance disconnecting switch interlock 1, including disconnecting switch 2, earthed switch 3, disconnecting switch transmission crank arm 4, disconnecting switch kinematic link 5, trundle 6, interlock plate 7, rotational pin 8, fixed plate 9, earthed switch transmission crank arm 10, earthed switch kinematic link 20.
Described earthed switch 1 is arranged on the lower section of disconnecting switch 2, and the inner of disconnecting switch transmission crank arm 4 is connected with the disconnecting switch 2 power transmission shaft outer end in disconnecting switch 2, and the outer end of disconnecting switch transmission crank arm 4 is hinged with the middle part of disconnecting switch kinematic link 5；The top of described interlock plate 7 is provided with elongated slot 71, the outer end of disconnecting switch kinematic link 5 is slipped in the elongated slot 71 on the top of interlock plate 7 by trundle 6, the bottom bending of interlock plate 7, form a kink 72, interlock plate 7 bending place is hinged in fixed plate 9 by rotational pin 8, the end, outer end of interlock plate 7 kink 72 is for limiting the motion of earthed switch transmission crank arm 10, there is leaning or depart from two kinds of earthed switch transmission crank arm 10 top duty, the inner of earthed switch transmission crank arm 10 is connected with the power transmission shaft outer end of earthed switch 3, the outer end of earthed switch transmission crank arm 10 is hinged with earthed switch kinematic link 20, fixed plate 9 is arranged on earthed switch 3.
In the present embodiment, described disconnecting switch transmission crank arm 4 has three, and the outer end of three disconnecting switch transmission crank arm 4 is all hinged with the middle part of disconnecting switch kinematic link 5.Described earthed switch transmission crank arm 10 has three, and the outer end of three earthed switch transmission crank arm 10 is all hinged with the middle part of earthed switch kinematic link 20.
Operation principle of the present utility model:
As shown in Figure 4, disconnecting switch kinematic link 5 is connected by trundle 6 with interlock plate 7, elongated slot 71 it is designed with on interlock plate 7, trundle 6 can slide in elongated slot 71, interlock plate 7 is connected with fixed plate 9 by rotational pin 8, disconnecting switch kinematic link 5 motion drives interlock plate 7 to rotate around rotational pin 8, the change of interlock plate 7 lower end kink 72 position relative with earthed switch transmission crank arm 10, it is achieved interlock or release interlocking.That is, when disconnecting switch is closed a floodgate, interlock plate 7 limits the rotation of earthed switch transmission crank arm 10；When disconnecting switch is closed a floodgate, earthed switch can not close a floodgate, it is achieved the disconnecting switch interlocking to earthed switch.
Emphasis of the present utility model is that the end utilizing interlock plate is for limiting the motion of earthed switch transmission crank arm.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
