Abstract
The utility model relates to an integral switching device for high-voltage enclosed type combination electrical apparatus, which belongs to the technical field of electric switches. An isolating switch and a grounding switch are installed in the same casing; a first supporting conductor and a second supporting conductor are respectively installed on the casing in an insulated manner, a moving contact opposite to a fixed contact is installed in a contact pedestal at the middle part of the casing, and when being adjacent to the position of the fixed contact, the moving contact is electrically connected with the fixed contact, and on the contrary, the moving contact is detached from electrical connection with the fixed contact; a displaceable grounding contact insulated with the casing is installed in a position where the casing is far away from the first supporting conductor; and when being positioned in the position adjacent to the contact pedestal, the grounding contact is electrically connected with the first supporting conductor, and on the contrary, the grounding contact is detached from electrical connection with the first supporting conductor through the contact pedestal. Since the isolating switch and the grounding switch are organically combined and arranged in the same casing, the utility model performs more compact function, effectively reduces the volume of the product, greatly enhances reliability and has better visual effect.
Description
Technical field
The utility model relates to a kind of electrical apparatus-switching device, and the integrated switched device of especially a kind of high-voltage closed combined electrical apparatus belongs to the appliance switch technical field.
Background technology
Understand according to the applicant, the isolation of high-voltage closed combined electrical apparatus (GIS) and earthed switch are the important component parts of GIS product, play irreplaceable effect in the GIS product.At present domestic ZF series GIS product all is that isolating switch and earthed switch are isolated fully, adhere to different air chambers separately, so just inevitably cause this part structure excessive, and small product size, weight and non-ferrous metal consumption have been increased, and having increased production cost and floor space, visual effect is also not ideal enough.
The utility model content
The purpose of this utility model is: the shortcoming at above prior art exists, a kind of compact conformation is proposed, and can effectively reduce the integrated switched device of high-voltage closed combined electrical apparatus of small product size.
In order to reach above purpose, high-voltage closed combined electrical apparatus integral switch device of the present utility model comprises isolating switch and earthed switch, and described isolating switch and earthed switch are installed in the same housing; By first and second insulating parts first and second supportive conductors are housed respectively on the described housing, the contact base that is electrically connected with first supportive conductors is equipped with at the middle part; Be equipped with in the described contact base be placed in second supportive conductors on the relative moving contact of fixed contact, when described moving contact is in contiguous fixed contact position, be electrically connected with fixed contact, when described moving contact is in away from the fixed contact position, be electrically connected with the fixed contact disengaging; Described housing is equipped with the be shifted grounding contact of insulation with it away from the first supportive conductors place, when described grounding contact is in the position of contiguous contact base, be electrically connected with first supportive conductors by contact base, when described grounding contact is in position away from contact base, break away from being electrically connected by contact base and first supportive conductors.
Because isolating switch and earthed switch are organically combined, be located in the same housing, therefore make function of the present utility model compact more, effectively reduced the volume of product, reliability also has bigger enhancing, and visual effect is better simultaneously.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
Embodiment one
The high-voltage closed combined electrical apparatus integral switch device of present embodiment as shown in Figure 1, the left end of housing 1 and lower end are equipped with first and second supportive conductors 4 and 5 by first and second insulating basins 2 and 3 respectively, upper end and right-hand member are installed insulated switch and Grunding switch gear device 6 and 7 respectively, and the contact base 8 that is electrically connected with first supportive conductors 4 is equipped with at the middle part.Be equipped with in this contact base be placed in second supportive conductors 5 on the relative moving contact 10 of fixed contact 9.This moving contact and contact base 8 constitute the vertical moving pair, and the upper end constitutes first toggle by insulated tension pole 11 and driving shaft 12.When the external electric pneumatic operating mechanism drives driving shaft 12 rotations, can drive moving contacts 10 through insulation pull bar 11 and be shifted up and down.When moving contact 10 was in the limit inferior position of contiguous fixed contact 9, the plug of its lower end was electrically connected with fixed contact 9, thereby reached the purpose of connecting outside major loop by the electrical connection that realizes first and second supportive conductors; When moving contact 10 is in position away from fixed contact 9, breaks away from fixed contact 9 and to be electrically connected the major loop disconnection.
Simultaneously, housing 1 right side is equipped with by insulating part and housing 1 and is constituted the grounding contact 13 that moves horizontally pair, the right-hand member of this grounding contact constitutes second toggle by pull bar 14 and rotating shaft 15, when the external electric pneumatic operating mechanism drives rotating shaft 15 rotations, can drive grounding contacts 13 through pull bar 11 and move to the limit on the left position that is electrically connected with ground connection fixed contact 16 on the contact base 8, thereby be electrically connected with first supportive conductors 4 by contact base, be grounded; When grounding contact was in position away from contact base 8 by drive, grounding contact 13 broke away from being electrically connected by contact base 8 and first supportive conductors 4.
Generally speaking, whether the two has direct electrical link isolation and earthed switch, decide a lateral electrode of isolating switch to be communicated with the earth by the operational grounding switch.Keep apart when normally sending electricity to close and close, earthed switch is opened, and the two switching logic is opposite during the trouble hunting.
Isolate and the two operating mechanism of earthed switch all places housing air outward, realize three synchronised (switch is in tank interior, fills the gas with SF6, and mechanism is in the tank body atmosphere outside) during operation.
Like this, insulated switch and earthed switch are in same housing, isolation and earthed switch are organically combined, two kinds of switches can be incorporated in the insulating gas air chamber, make the high-voltage closed combined electrical apparatus integral switch device of present embodiment very compact, effectively reduced small product size, its reliability also has bigger enhancing, and the visual effect of observing switch motion simultaneously is better.Can reach more than 6000 times the mechanical endurance that experiment showed, this switching device.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
