Abstract
The utility model discloses a kind of 500 kilovolts of outlet upside-down mounting fittings, solve the problems, such as that 500kV conductors on quad bundled can not be directly entered substation.Including pipe bus (7), pipe mother T-type fitting (6) there are two being positioned apart from pipe bus (7), a word Technology of Hydraulic Terminal Connector (5) is connected on each pipe mother T-type fitting (6), heat-resisting aluminum conductor (4) are connected in the other end of a word Technology of Hydraulic Terminal Connector (5), a word screw bolt-type device clamp (3) is connected in the other end of heat-resisting aluminum conductor (4), U-shaped upside-down mounting fitting connector (1) is connected between the other end of two word screw bolt-type device clamps (3), the double splitter wire clamps (2) of two B-shaped are provided on U-shaped upside-down mounting fitting connector (1).The utility model meets the requirement that 500kV conductors on quad bundled is directly entered substation, and meets the requirement of pulling force.
Description
Technical field
The utility model relates to a kind of 500kV outlet upside-down mounting fittings, are suitable for 500kV conductors on quad bundled, are four points a kind of
Aluminium hydraulic pressed connecting pipe upside-down mounting fitting is split, horizontal direction grip 10000N is born at fitting aluminium hydraulic pressed connecting pipe, vertical direction pulling force is greater than 3000N, gold
Tool will not deform.
Background technique
Substation location is limited, and outlet line corridor is limited, the line terminal 500kV tower portal frame distance in substation
It is relatively close, it is series-connected in station according to conventional strain insulator, since route twisted wire is apart from too short, influences whether the twisted of conducting wire aluminium stock
Power, aluminium single line is possible to the phenomenon that generating " bulge ", to damage conducting wire；Therefore, route profession cancels terminal tower and gantry
The strain insulator-string of frame two sides is changed to V-type string, and line conductor need to be directly connected on upside-down mounting fitting, because line conductor is quadripartion, passes through
After V-type string transition, conventional flip chip fitting line side can only connect double bundle conductor, cause route conductors on quad bundled can not directly into
It stands.
Summary of the invention
The utility model provides a kind of 500 kilovolts of outlet upside-down mounting fittings, and solving 500kV conductors on quad bundled can not be direct
The technical issues of into substation.
The utility model is to solve the above technical problem by the following technical programs:
A pipe mother T-type gold is respectively arranged at the both ends of pipe bus in a kind of 500 kilovolts of outlet upside-down mounting fittings, including pipe bus
Tool, is connected with a word Technology of Hydraulic Terminal Connector on each pipe mother T-type fitting, connects in the other end of a word Technology of Hydraulic Terminal Connector
It is connected to heat-resisting aluminum conductor, a word screw bolt-type device clamp is connected in the other end of heat-resisting aluminum conductor, in two word screw bolt-types
It is connected with U-shaped upside-down mounting fitting connector between the other end of device clamp, is provided with two on U-shaped upside-down mounting fitting connector
The double splitter wire clamps of a B-shaped.
What the route conductors on quad bundled outside the double splitter wire clamps of two B-shaped and substation was connected together, pipe is female
Line is clamped together with vertical telescopic in substation every knife moving contact.
The utility model meets the requirement that 500kV conductors on quad bundled is directly entered substation, and meets wanting for pulling force
It asks.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the utility model in main view direction；
Fig. 2 is structural schematic diagram of the utility model in left view direction.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing:
A kind of 500 kilovolts of outlet upside-down mounting fittings, including pipe bus 7, are respectively arranged pipe mother's T-type at the both ends of pipe bus 7
Fitting 6 is connected with a word Technology of Hydraulic Terminal Connector 5 on each pipe mother T-type fitting 6, in the another of a word Technology of Hydraulic Terminal Connector 5
One end is connected with heat-resisting aluminum conductor 4, a word screw bolt-type device clamp 3 is connected in the other end of heat-resisting aluminum conductor 4, at two one
U-shaped upside-down mounting fitting connector 1 is connected between the other end of word screw bolt-type device clamp 3, in U-shaped upside-down mounting fitting connector
The double splitter wire clamps 2 of two B-shaped are provided on 1.
The double splitter wire clamps 2 of two B-shaped are connected together with the route conductors on quad bundled outside substation, pipe
Bus 7 is clamped together with vertical telescopic in substation every knife moving contact, and realization upside-down mounting fitting is electrical with power transformation station equipment
Connection.
The utility model quadripartion aluminium hydraulic pressed connecting pipe upside-down mounting fitting, is able to solve the problem of 500kV conductors on quad bundled directly enters the station,
And 10000 Ns of horizontal direction grip are born at fitting aluminium hydraulic pressed connecting pipe, vertical direction pulling force is greater than 3000 Ns, and fitting does not become
Shape, longtime running current-carrying capacity also meet the service requirement of 4000 peaces.
