Abstract
The utility model relates to an interphase diverging row which comprises a diverging pipe and two connecting joints which are arranged at the two ends of the diverging pipe, wherein each connecting joint is an L-shaped plate, the two ends of the diverging pipe are correspondingly and vertically fixed on the outer plate surface of one side plate of the corresponding connecting joint, and the other side plate of the connecting joint is provided with a screw bolt connecting hole. By changing the traditional sheet-shaped diverging row to the pipe-shaped diverging row, the time diverging row increases the carrying capacity, and reduces the deformation of the diverging pipe caused by the environmental factors such as the external force and the like, thereby guaranteeing the reliability of the diverging row.
Description
Technical field
The utility model relates to the Cubicle Gas-Insulated Switchgear technical field, especially a kind of alternate water conservancy diversion row.
Background technology
When Cubicle Gas-Insulated Switchgear adopts direct multipoint earthing, the electric current that earth connection passes through approximately is about 30% of a main circuit current, when main circuit current is smaller, do not have any problem, but when the electric current that major loop passes through increases, because the induced current in the earth connection is excessive, can produce problems such as heating.In order to reduce the induced current in the earth connection, adopt usually at present between the three-phase housing, to connect the method that alternate water conservancy diversion row is set, make electric current pass through surface of shell.By the ultra high voltage gas insulated combined electric appliance equipment is estimated to the computational analysis of ground network injection overvoltage electric current with to the induced current on the phase-splitting housing, water conservancy diversion row is set at the two ends in loop, the induced current of housing is most of to be handled by alternate water conservancy diversion row, can be controlled in below 5% of main circuit current (three-phase parallel section) thereby make by the induced current in the vertical junction ground wire.General flat aluminium row or the copper bar (as shown in Figure 1) of adopting of conventional water conservancy diversion row, but, because the spacing of ultra high voltage sleeve pipe is big (being generally 15 meters), so aluminium row's length is longer accordingly, through long-time running, because aluminium row is oversize, be subjected to the influence of external force (as wind-force etc.) effect simultaneously, aluminium row can produce gross distortion, so both influence water conservancy diversion row's through-current capability, also influenced water conservancy diversion row's outward appearance.
Summary of the invention
The purpose of this utility model is to provide a kind of alternate water conservancy diversion row, produces the problem of distortion greatly owing to span to solve traditional water conservancy diversion row.
For achieving the above object, the utility model adopts following technical scheme: a kind of alternate water conservancy diversion row, this alternate water conservancy diversion package is drawn together mozzle and is arranged at the jointing at mozzle two ends.
Described jointing is a L shaped plate, and the both ends correspondence of mozzle is vertically fixed on the outer plate surface of a side plate of corresponding jointing, and another side plate of jointing is provided with bolt connecting hole.
Between two side plates, be provided with floor on the described jointing.
The plane at the side plate place that is provided with bolt connecting hole of described two jointings is orthogonal.
The plane at the side plate place that is provided with bolt connecting hole of described two jointings is parallel to each other.
Described mozzle is made by aluminium-alloy pipe.
Described jointing one is fixedly installed on the two ends of mozzle.
The utility model changes the water conservancy diversion of traditional sheet row into tubulose, has increased water conservancy diversion row's non-deformability, has reduced the mozzle distortion that environmental factors such as external force cause.Jointing adopts L shaped plate, can well be adaptive with the shape of sleeve pipe; Between two side plates of jointing, floor is set, has further guaranteed water conservancy diversion row's installation strength; The perpendicular or parallel setting of the side plate that is provided with bolt connecting hole on two jointings can realize many water conservancy diversion rows' connection easily, and described mozzle is made with aluminium alloy, can guarantee the intensity of mozzle.
Description of drawings
Fig. 1 is traditional water conservancy diversion row's a structural representation;
Fig. 2 is an alternate water conservancy diversion row's of the present utility model structural representation.
Embodiment
As shown in Figure 2, a kind of alternate water conservancy diversion row comprises mozzle 1 and the jointing 2 that is fixedly set in the mozzle two ends, and mozzle 1 adopts aluminium-alloy pipe antirust and that intensity is high, jointing 2 adopts aluminium sheet or copper coin, and jointing 2 is fixed on the mozzle by the mode of welding; Jointing 2 is L-shaped, be provided with the floor 9 that is used to strengthen between the biside plate of jointing 2, jointing 2 is provided with bolt connecting hole 3 with the side plate of mozzle parallel axes, bolt connecting hole 3 is used for being connected of water conservancy diversion row and collar supports tube or realizes that water conservancy diversion is arranged and water conservancy diversion docking between arranging, it is orthogonal that described two jointings are provided with the plane at side plate place of bolt connecting hole 3, certainly, in other embodiments, the plane that described two jointings are provided with the side plate place of bolt connecting hole 3 also can be arranged in parallel, butt joint between the realization two water conservancy diversion row that like this can be convenient, in use, wherein mutually a sleeve pipe is fixedly connected in water conservancy diversion row's a end and the electric wire three-phase, the other end connects with adjacent one mutually sleeve pipe, certainly, when water conservancy diversion row's length is not enough, can adopt the form of a plurality of water conservancy diversion row butt joint, water conservancy diversion row can dock by its jointing 2 usefulness bolt.
