Description
Technical field
The utility model relates to the High-Voltage Electrical Appliances lightning arrester, particularly a kind of partition apparatus of lightning arrester.
Background technology
In the high-tension electricity transmission facility, the general supporting lightning arrester that is equipped with in the high pressure combined electrical apparatus, but in the withstand voltage test of high pressure combined electrical apparatus, need to disconnect lightning arrester is removed lightning arrester during the method for employing, wastes time and energy, and is extremely inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of partition apparatus of lightning arrester.This device can conveniently disconnect lightning arrester when the high pressure combined electrical apparatus is done withstand voltage test, makes when the high pressure combined electrical apparatus is done withstand voltage test, and is simple to operation, the test efficiency height.
In order to achieve the above object, technical scheme of the present utility model is achieved in that a kind of partition apparatus of lightning arrester, it is characterized in that, comprise housing, be provided with spring and slide block in the cavity of housing, one end of described housing is fixed with conducting rod, its other end is provided with opening, is penetrated with slidably jacking block in the opening, and an end of described jacking block stretches out described opening, the other end and described slide block are fixed, described spring roof pressure slide block; And jacking block, cushion block, housing, conducting rod constitute leading electric pathway.
Further improvement of the utility model is:
All there is opening at the two ends of described housing, and an end of conducting rod stretches into housing, fixes by straight pin.
Described cushion block is connected by the conductive strips that are arranged in the housing with conducting rod.
Be provided with lining between described jacking block and the housing.
The side of described housing is provided with at least one through hole.
One end of the utility model housing is provided with opening, is penetrated with slidably jacking block in the opening, and an end of this jacking block stretches out described opening, and the slide block of the other end and housing inner chamber is fixed, the spring roof pressure slide block of housing inner chamber.Jacking block connects lightning arrester, and conducting rod connects High-Voltage Electrical Appliances, but the jacking block elastic shrinkage, so this partition apparatus is removed the convenient lightning arrester that disconnects easily.
Cushion block of the present utility model is connected by the conductive strips that are arranged in the housing with conducting rod, and electric conductivity can not be considered in the selection of case material, but the choice is big; Conducting rod is generally with high-pressure conductor and is threaded, and the side of housing is provided with at least one through hole, extracting tools such as convenient use lever.
Description of drawings
Fig. 1 is a kind of partition apparatus structural representation of lightning arrester.
Embodiment
With reference to Fig. 1, the partition apparatus of lightning arrester comprises housing 2, and all there is opening at the two ends of housing 2, and an end is installed conducting rod 8, and the other end is installed column jacking block 1, is provided with helical spring 5 and slide block 3 in the column cavity of housing 2, helical spring 5 roof pressure slide blocks 3.One end of jacking block 1 stretches out housing 2, compresses with the splicing ear of lightning arrester, forms to be electrically connected; The other end has a concave station, passes and slide block 3 centers, and is fixing by self-locking nut 4.Conducting rod 8 is a column platform shape structure, and the one end stretches into housing 2, interference fit, and fixing by straight pin 7, this end end face is as another roof pressure face of helical spring 5; Other end periphery has screw thread, by the high-pressure conductor of the GIS High-Voltage Electrical Appliances that are threaded.Be provided with polytetrafluoroethylene bushing 9 between jacking block 1 and the housing 2, can reduce the friction of 2 of jacking block 1 and housings, be convenient between the two relative motion neatly.
Slide block 3 is connected by the conductive strips 6 that are arranged in the housing 2 with conducting rod 8.Leading electric pathway is made up of conducting rod 8, conductive strips 6, slide block 3, jacking block 1, and therefore, housing 2 can select for use the lower cost materials of conductive capability difference to make, for example cast iron.The side of housing 2 is provided with four-way hole 10, when dismounting or installation, and instruments such as convenient use lever.
The lightning arrester that will have partition apparatus cooperates with the GIS combined electrical apparatus, during as withstand voltage test, pulls down partition apparatus, makes GIS combined electrical apparatus and lightning arrester disconnect on electric; When the GIS combined electrical apparatus is finished withstand voltage test, load onto partition apparatus, make the GIS combined electrical apparatus on electric, be connected with lightning arrester.
Claims (5)
