Change cable terminal structure.
Background technology
Cubicle Gas-Insulated Switchgear（Hereinafter referred to as GIS combination electric appliance）It is important defeated for power network
One of transformer, safe operation of its security reliability to power network are most important.
The Process of Urbanization Construction that the country develops increasingly now, it is especially prominent to the Miniaturization Design of power transmission and transforming equipment.Especially body
In present GIS combination electric appliance, such as Shanghai, Jiangsu grid company, because GIS rooms area is small, compartment is away from common demands at 1 meter
Within, more have and very require to accomplish 0.8 meter.This will have the design of smallerization for GIS combination electric appliance, and prominent design will
Ask be exactly GIS combination electric appliance arrangement will more rationally, size, volume it is smaller.GIS combination electric appliance cable termination at present, it is arranged in three
Below station disconnecting switch, but because cable termination outer cover height is too high, cause end mounting surface apart from floor measurements mistake
Small, end directly can not be inserted directly into cable tank from interlayer below GIS rooms, and this causes not small to live installation, experiment
Trouble.
The content of the invention
The utility model is overcome the deficiencies in the prior art, changes the connected mode of cable termination, optimizes internal connect
The size and insulation distance of conductor, while in view of experiment of the scene to end, optimize the structure that inner conductor connects.
To achieve the above object, a kind of miniaturization cable terminal structure of three-phase combined type combined electrical apparatus, including three are designed
Station disconnecting switch, three stations connection conductor, cable termination, end, it is characterised in that：The lower end of tri-station isolating switch connects
Connect cable termination；The inside of described tri-station isolating switch is provided with three stations connection conductor, and three stations connect the lower end of conductor
Conductor connection cables head is connected using cable termination；Described end is located at the inside of cable termination.
Described cable termination connection conductor is made up of conducting rod and connecting plate, and forms L-type structure, and the connection of three stations is led
One end of the lower end connection conducting rod of body, the other end connection connecting plate of conducting rod.
Conductive pad is provided between described cable termination connection conductor and end.
The outer sheath of described cable termination connection conductor is provided with cable termination shell, and the top of cable termination shell is provided with
One wire hole, the bottom of cable termination shell are laid with three another wire holes；Set positioned at the side of cable termination shell
There are two hand holes, and two hand holes are in 145 ° of arrangements.
The utility model compared with the existing technology, by the connection of tri-station isolating switch side outlet is changed to tri-station isolating switch
Lower outlet connection, reduce the length of GIS combination electric appliance equipment.Inner connecting conductors electric field is optimized simultaneously, reduced
Shell sizes, add the distance on end mounting surface and ground, it is ensured that end mounting surface is not less than apart from ground
600mm, facilitate the installation of on-site cable head.The cable termination connection conductor of design simultaneously, 4 installation screws and 2 of connecting plate
The position of individual installation hand hole, the dismounting cable termination of field test is facilitated to connect conductor.The miniaturization cable terminal structure is simple,
It is easy for installation, save space.
Brief description of the drawings
Fig. 1 is the utility model installation effect figure.
Fig. 2 is the utility model installation diagram.
Fig. 3, Fig. 4 are cable termination shell mechanism schematic diagram.
Referring to Fig. 2,1 is tri-station isolating switch, and 2 be that three stations connect conductor, and 3 be that cable termination connects conductor, and 3-1 is
Conducting rod, 3-2 are connecting plate, and 4 be conductive pad, and 5 be end, and 6 be cable termination.
It is cable termination shell referring to Fig. 3, Fig. 4,7,8 be hand hole, and 9 be wire hole, and 10 be another wire hole.
Embodiment
The utility model is described further below according to accompanying drawing.
