Make, measure, the critical function such as protection.Existing extra-high voltage switching device bulky dimensions, floor space is big；Transport needs to disintegrate, peace
The dress cycle is long；Using SF6 gas flow many, greenhouse gas emissions are big.The present invention is designed by optimization, reduces component size, excellent
Change arrangements of components, it is achieved Combined electric appliance whole Transporting.
Summary of the invention
In order to overcome disadvantages mentioned above, it is an object of the invention to provide and a kind of can combine with the compact combined type of whole Transporting
Electrical installation, builds for extra-high-voltage alternating current 750kV transformer station or direct current ± 800kV current conversion station.
For reaching above-mentioned purpose, the present invention adopts the technical scheme that: whole compact compound combined electrical equipment device bag
Containing miniaturization breaker, current transformer, VL type bus, VG type bus, miniaturization disconnecting switch, inlet-outlet sleeve, underframe etc..
Devise the circuit breaker element of miniaturization, current transformer is horizontally disposed, and with VL type bus modularization, with breaker even
Connect.Disconnecting switch landing layout, reduces height, the VG bus being shortened by is connected with current transformer, reduction axial length.
Use compound insulating sleeve line, improve antiseismic grade.During transport, two casing bits are removed individually transport, other portions
Part is fixed on the underframe being welded by H profile steel, and owing to whole height is less than 2m less than 3.5m, width, length is less than 15m,
Gross weight is less than 14 tons, therefore can use automobile whole Transporting.After reaching the spot, it is only necessary to docking casing bit, greatly subtract
Little work on the spot amount, improves installation rate.
The present invention devises, the circuit breaker element of miniaturization, and with body on the same axis, axis terrain clearance is in mechanism
1145mm；Line pulls out mouth on tank body top, and two spacings pulling out mouth are 2990mm.
The present invention devises, and current transformer and VL type bus composite module, current transformer is horizontally disposed.
Present invention optimizes VG type bus structure, shorten bus length.
The present invention devises, and minimizes disconnecting switch element, and disconnecting switch lands layouts, and height is less than 3.3m.
The present invention devises inlet-outlet sleeve device, is made up of compound insulating sleeve and tee bus element.
The distinguishing feature of the technical program is: owing to breaker minimizes, tank diameter is little, and mechanism is coaxial with body, fall
The low height of breaker, lays a good foundation for reducing compound combined electrical equipment device whole height；Due to breaker line
Pull out mouth on tank body top, shorten the distance between the current transformer being attached thereto, for shortening compound combined electrical equipment device
Entire length provides guarantee；Due to disconnecting switch miniaturization of components, use simultaneously and land layouts, solve disconnecting switch and transport
The technical barrier of superelevation；Use compound insulating sleeve, and use low position, improve compound combined electrical equipment device antiseismic
Ability.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings invention is explained.
Accompanying drawing 1 is the structural representation of the present invention.
In figure, 1 inlet-outlet sleeve device, 2 miniaturization disconnecting switch, 3 current transformers, 4VL type bus, 5 miniaturization breakers,
6 VG type buses, 7 underframe.
Detailed description of the invention
Accompanying drawings specific embodiments of the present invention are: whole compact compound combined electrical equipment device is included into
Thread casing device (left 1), miniaturization disconnecting switch (2), current transformer (3), VL type bus (4), miniaturization breaker (5),
VG type bus (6), outlet casing tube device (right 1), underframe (7) etc..Devise the breaker (5) of miniaturization, mechanism and breaker
On the same axis, axis terrain clearance is 1145mm to body, establishes for reducing compound combined electrical equipment device whole height
Basis；Line pulls out mouth on tank body top, and two spacings pulling out mouth are 2990mm.Current transformer (3) is horizontally disposed, and with
VL type bus (4) modularization, is installed to breaker (5) two and vertically pulls out the top of mouth.Miniaturization disconnecting switch (2) tank diameter is
1250mm, height be 3300mm, lands layouts, and VG type bus (6) being shortened by is connected with current transformer (3), and reduction is answered
Box-like combined electrical apparatus entire length.Inlet-outlet sleeve device (1) is made up of compound insulating sleeve and tee bus element, line
VG type bus (6) that casing bit (1) is shortened by is connected with disconnecting switch (2).It is multiple that all above element constitutes compact
