Abstract
The utility model discloses a capacitor bank grounding knife switch mechanism comprising a mechanism box body. The mechanism box body is vertically connected to a knife switch bracket by the aid of a fixed steel channel. An opening/closing door of the mechanism box body is perpendicular to the horizontal plane and is of a side-opening or up-and-down opening/closing structure. The mechanism box body is internally provided with an auxiliary switch which is connected to the inner wall of the mechanism box body by the aid of a bolt. An insulating base plate is arranged between the auxiliary switch and the inner wall of the box body. The mechanism box body is externally provided with a grounding knife switch operating device, and one side of the auxiliary switch is connected with the grounding knife switch operating device through a transmission output shaft. As the capacitor bank grounding knife switch mechanism is arranged vertically, the sealing structure of the box body is changed from a horizontal sealing mode to a vertical sealing mode, the box body can be sealed more tightly, the phenomenon that water is accumulated on the horizontal bottom plate of the box body in rainy day to cause direct-current grounding and auxiliary switch contact corrosion is eliminated, and safe and reliable operation of equipment inside substations is ensured.
Description
Technical field
The utility model relates to a kind of vertically arranged capacitor group grounding switch mechanism.
Technical background
At present, most capacitor group grounding switch is GW8 type, and mode of operation is vertical operation, and mechanism is arranged horizontally mode.While being operated, auxiliary switch pull bar is limit, and this mechanism is poorly sealed, in rainy day casing, is easy to ponding, cause DC earthing, in addition, the long-term ponding of horizontal level, also causing in-house auxiliary switch contact corrosion, there is DC earthing or pilot signal malposition in fine day.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of sealing property that can guarantee preferably mechanism's casing, eliminates the capacitor group grounding switch mechanism casing of rainy day water inlet hidden danger.
The utility model adopts following technical scheme: a kind of capacitor group grounding switch mechanism, its key technology is: it comprises mechanism's casing, described mechanism casing is vertically connected on disconnecting link support by fixing channel-section steel, the switch gate of described mechanism casing is vertical with horizontal plane, and for side is opened or upper and lower opening and closing structure, in described mechanism casing, be provided with auxiliary switch, described auxiliary switch is connected on mechanism's cabinet wall by bolt, between described auxiliary switch and cabinet wall, be provided with insulating pad, the external grounding switch operating means that is provided with of described mechanism case, described auxiliary switch one side is connected with grounding switch operating means by transmission output shaft.
The beneficial effect that adopts technique scheme to produce is: the utility model structure is arranged vertically, thereby changed the hermetically-sealed construction of casing, from horizontal seal mode, changed vertical seal mode into, make box sealing tighter, casing horizonal base plate ponding while also having stopped the rainy day, cause the situation of DC earthing and auxiliary switch contact corrosion, guaranteed the safe and reliable operation of power transformation station equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the position view that this Novel assistant switch and mechanism case body divide;
Wherein, fixedly channel-section steel, 6 insulating pads, 7, switch gate of 1 transmission output shaft, 2 auxiliary switches, 3 mechanism's casings, 4 grounding switch operating means, 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Referring to accompanying drawing 1 and accompanying drawing 2, the present embodiment comprises transmission output shaft 1, auxiliary switch 2, mechanism's casing 3, grounding switch operating means 4, fixedly channel-section steel 5, insulating pad 6, described mechanism casing 3 is connected with fixing channel-section steel 5 by bolt, auxiliary switch 1, insulating pad 6 are bolted on mechanism's casing 3 inside, insulating pad 6 is between auxiliary switch 2 and mechanism's casing 3, and auxiliary switch 2 passes on left transmission output shaft 1 and connects capacitor group grounding switch operating means 4.The switch gate 7 of described mechanism casing 3 is vertical with horizontal plane, and switch gate is that laterally opened structure or upper and lower opening and closing structure (can install in sidepiece, top or bottom hinge additional and realize switching, also can adopt other structures), switch gate 7 is subject to 3 protection of mechanism's casing like this, and rainwater is difficult for entering.
When the utility model is used, first mechanism's casing 3 is bolted on fixedly on channel-section steel 5, then auxiliary switch 2 and insulating pad 6 are bolted on to mechanism's casing 3 inside, again auxiliary switch 2 is connected with transmission output shaft 1 by bolt, finally output shaft 1 is connected and forms being arranged vertically of capacitor group grounding switch mechanism's casing with grounding switch operation part 4.Fixedly channel-section steel 5 is connected on disconnecting link support and (is also disconnecting link bearing).
Capacitor group grounding switch of the present utility model mechanism casing is arranged vertically the hermetically-sealed construction that has changed casing, from horizontal seal mode, changed vertical seal mode into, make box sealing tighter, casing horizonal base plate ponding while also having stopped the rainy day, cause the situation of DC earthing and auxiliary switch contact corrosion, guaranteed the safe and reliable operation of power transformation station equipment.
