Utility model content
The purpose of this utility model is to provide a kind of and takes up room little and the pipe bus that can prevent corona from producing connects gold utensil.
In order to solve the problem, the technical solution of the utility model is:
Pipe bus connects gold utensil, comprises the bus anchor ear that axis extends in left-right direction, by grading ring that grading ring support and connection have the axis being located on bus anchor ear periphery to extend in left-right direction on bus anchor ear.
Bus anchor ear and described grading ring are coaxially set.
Described grading ring is positioned at the center position place of bus anchor ear.
Bus anchor ear is comprised and to be fixed together first anchor ear and second anchor ear by connecting bolt.
Bus anchor ear is provided with the radial backing pin for contacting to prevent left and right pipe end of bus bars with the spacing cooperation in the end of respective tube bus.
Described grading ring supports and comprises around the uniform multiple radial connecting plate of grading ring circumference, and the head end of each radial connecting plate is fixedly arranged on grading ring, and the end of each radial connecting plate overhangs towards the centerline direction of grading ring and is fixedly connected with described bus anchor ear.
Described bus anchor ear is provided with the anchor ear connecting plate for being connected with corresponding radial connecting plate by connecting plate bolt.
Described anchor ear connecting plate be fixedly welded on described bus anchor ear or anchor ear connecting plate and described bus anchor ear one-body molded.
The beneficial effects of the utility model are: be called left pipe bus and right pipe bus by needing two the pipe buses connected, during use, left pipe bus is fixed on the left end of bus anchor ear, right pipe bus is fixed on the right-hand member of bus anchor ear, grading ring is supported by grading ring and is fixed on bus anchor ear, grading ring increases corona voltage, prevent valve Room gold utensil because of the harm of overtension generation corona, solve the problem of corona and radio interference, the simultaneously ring footpath of grading ring and pipe bus at right angle setting, save the space on left and right directions, when valve Room limited space, save installing space, be conducive to installation and the layout of miscellaneous equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of embodiment 2 of the present utility model.
Embodiment
Pipe bus connects the embodiment 1 of gold utensil as shown in Figure 1 and 2: comprise the bus anchor ear 13 that axis extends all in left-right direction, and bus anchor ear comprises first anchor ear and second anchor ear of being linked together by bolt 12.The grading ring 2 that bus anchor ear 13 has the axis being located on bus anchor ear periphery to extend in left-right direction by grading ring support and connection, bus anchor ear and grading ring are coaxially set, and grading ring is positioned at the center position place of bus anchor ear.Bus anchor ear is provided with the radial backing pin 9 for contacting to prevent left and right pipe end of bus bars with the spacing cooperation in the end of respective tube bus, radial backing pin is spring cylindrical pin, and spring cylindrical pin is installed in the backing pin installing hole that bus anchor ear is arranged.Grading ring supports and comprises around four uniform radial connecting plates 6 of grading ring circumference, the head end of each radial connecting plate is fixedly arranged on grading ring 2, the end of each radial connecting plate overhangs towards the centerline direction of grading ring, the thickness of slab direction of radial connecting plate is vertical with left and right directions, the intensity of radial connecting plate can be ensured like this, when being subject to the axial force of left and right directions of grading ring or pipe bus, radial connecting plate also can not produce distortion, on bus anchor ear, welding is installed with four corresponding with each radial connecting plate respectively anchor ear connecting plates 7, each anchor ear connecting plate 7 is fixedly connected with by connecting plate bolt 11 with corresponding radial connecting plate 6.
The utility model is owing to adopting coupling scheme, it not only meets current-carrying demand, simultaneously because bus anchor ear is bolted, be convenient to dismounting and install, left pipe bus 1, right pipe bus 4 can be first installed during installation, bus anchor ear is installed again, when dismantling simultaneously, can first dismantle bus anchor ear, then dismantle left and right pipe bus, the bus anchor ear be bolted as seen, not only ensure that the current capacity of gold utensil itself, be convenient to installation and removal, when valve Room limited space, advantage is more obvious simultaneously; The grading ring being located on bus anchor ear periphery increases corona voltage and prevents 1100kv(or other electric pressure) valve Room gold utensil is because of overtension, produce the harm of corona, the setting of visible grading ring, prevent the generation of corona, solve the problem of corona and radio interference, grading ring and bus anchor ear are coaxially set and more contribute to ensureing corona requirement; The radial direction of grading ring and the axial vertical of pipe bus, saved space, left and right, when valve Room limited space, saved installing space, be conducive to installation and the layout of miscellaneous equipment; Grading ring and bus anchor ear are bolted, and are convenient to the transport of gold utensil, dismounting and installation; Radial backing pin on bus anchor ear and the right side of left pipe bus and/or the left end of right pipe bus is spacing coordinates, left and right pipe bus does not directly contact, and has gap between the opposing end surface of left and right pipe bus, is namely convenient to heat radiation and in turn ensure that current-carrying intensity.This pipe bus connect gold utensil not only can be applied in the earthed switch of the valve Room, but also can be applied to any needs connect two pipe buses between.
In other embodiment of the present utility model: the thickness of bus anchor ear and length can carry out thickening or extending as required, to meet the requirement of gold utensil ampacity; Bus anchor ear and grading ring also can be arranged by different axis, such as axis between them is parallel to each other; Grading ring also can not be positioned at the center position place of bus anchor ear, such as grading ring is relatively near left end or the right-hand member of bus anchor ear; Spring cylindrical pin can also be replaced by square cotter, straight pin or other radial backing pin, and certain radial backing pin can not also be established; The number of the radial connecting plate during grading ring supports can also be three, five or other quantity, and it can also be the supporting construction that other is connected with bus anchor ear for realizing grading ring that grading ring supports; Anchor ear connecting plate can not also be established, and now radial connecting plate can be directly welded on bus anchor ear.
Pipe bus connects the embodiment 2 of gold utensil as shown in Figure 3: as different from Example 1, each anchor ear connecting plate 7 is all shaping with bus anchor ear 13 integrally casting for embodiment 2.
