Description
Technical field
The utility model belongs to High-Voltage Electrical Appliances, is specifically related to a kind of fixed contact for rotary combined electrical apparatus isolation, earthed switch.
Background technology
At present, for the isolation of rotary gas insulated metal closed switch equipment, static contact of grounding switch structure is that many group spring touch fingers are evenly arranged on the static contact panel of both sides mostly, between the static contact panel of both sides, spacing is fixed, and the position of disconnecting link is also fixing, such structural design not only requires that parts machining precision is very high, and cause sizable difficulty to assembling, because multiple parts produce accumulated error, be difficult to allow disconnecting link and both sides spring touch finger centering, thus affect through-current capability, also breaking-closing operating resistance is made to increase, there is the phenomenon of clamping stagnation, when separating brake, fingertip likely and between disconnecting link produces electric arc in addition, cause fingertip scaling loss, so just greatly reduce useful life and the reliability of product.
Utility model content
The purpose of this utility model is for above defect, and propose a kind of fixed contact for rotary combined electrical apparatus isolation, earthed switch, object is the useful life and the reliability that improve product.
The technical solution of the utility model:
Isolate for rotary combined electrical apparatus, the fixed contact of earthed switch, comprise fixed contact pedestal, fixed contact pedestal is provided with two static contact panels relatively established, two static contact panels are perpendicular to the upper surface of fixed contact pedestal, it is characterized in that: described fixed contact pedestal upper end is provided with support, two static contact panels are located at the both sides of support respectively, and by pin through two static contact panels and support, spring is equipped with in Chuan Xiao position, described pin two ends, spring end is provided with plain cushion and split pin, described static contact panel is equipped with on the two sides of support organizes watchband-shaped contactor more, described watchband-shaped contactor is fixed on static contact panel by many group locking bands, described fixed contact pedestal outside is provided with radome, described radome is connected with fixed contact pedestal by trip bolt.
Described static contact panel middle inside is provided with groove, and described support both sides are provided with the projection with described fit depressions.
Described static contact panel upper end inner inlet is provided with fillet.
Described support is arranged on fixed contact pedestal by trip bolt.
The beneficial effect of utility model:
The utility model is isolated, static contact of grounding switch is simple and reliable for structure, owing to floating in fixed contact and disconnecting link position, can automatic capturing when disconnecting link rotary cutting changes jobs position, decrease the difficulty of processing and assembling, in addition in the time of falling bus, electric arc can be produced between disconnecting link and fixed contact, this Novel fixed contact can in the time of falling bus, two static contact panel top spacing can reduce under the action of the spring automatically, spacing is less than the thickness of disconnecting link plate, the electrical arc erosion produced between such disconnecting link and fixed contact be the fingertip assembled in static contact panel instead of static contact panel, and the position of static contact panel meeting scaling loss has copper tungsten to protect, copper tungsten has very strong resistance to scaling loss ability, so just greatly improve reliability and the useful life of switch, watchband-shaped contactor is organized in fixed contact assembling more in addition, coefficient of friction is low, operation resistance is little, through-current capability is strong.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
One is as shown in Figures 1 to 4 used for the isolation of rotary combined electrical apparatus, the fixed contact of earthed switch, comprise fixed contact pedestal 1, fixed contact pedestal 1 is provided with two static contact panels 3 relatively established, two static contact panels are perpendicular to the upper surface of fixed contact pedestal 1, described fixed contact pedestal 1 upper end is provided with support 2, two static contact panels are located at the both sides of support 2 respectively, and by pin 4 through two static contact panels and support 2, spring 5 is equipped with in Chuan Xiao position, described pin 4 two ends, spring 5 end is provided with plain cushion and split pin 6, described static contact panel 3 is equipped with many group watchband-shaped contactors 10 on the two sides of support 2, described watchband-shaped contactor 10 is fixed on static contact panel 3 by many group locking bands, described fixed contact pedestal 1 outside is provided with radome 7, described radome 7 is connected with fixed contact pedestal 1 by trip bolt 8, described static contact panel 3 middle inside is provided with groove 3-1, described support 2 both sides are provided with the projection 2-1 matched with described groove 3-1, described static contact panel 3 upper end inner inlet is provided with fillet 9, described support 2 is arranged on fixed contact pedestal 1 by trip bolt 12.
Specific works process:
As shown in Figure 4, disconnecting link can do 360 degree of rotary motions under the driving of multistation mechanism, realize the conversion of multiple station, disconnecting link floats in finite gap between two side conductors, in the time of falling bus, two disconnecting links one do motion of closing a floodgate, another does separating brake motion, because disconnecting link and fixed contact float during combined floodgate, and have fillet, disconnecting link will automatic alignment, two static contact panels are softened, the contacting with disconnecting link of watchband-shaped contactor uniform close on static contact panel under the action of the spring, complete feed motion, another disconnecting link does separating brake action, when disconnecting link is separated with fixed contact, two static contact panels under the action of the spring, spacing between top is shunk automatically, producing strong electric arc between such disconnecting link and fixed contact will be introduced on two static contact panels, instead of on watchband-shaped contactor, avoid the scaling loss of watchband-shaped contactor, complete separating brake action.
To sum up, the utility model accomplishes the end in view.
