Description
Technical field
This utility model is related to electrical equipment technical field, more particularly, to a kind of sf6 looped network pt cabinet body structure.
Background technology
Sf6 gas-insulated ring network cabinet is by important to bus, chopper, on-load switch, disconnecting switch etc. high voltage device
It is enclosed in the medium voltage electricity equipment in the stainless steel case body of the sf6 gas being filled with lower pressure.Its prominent feature be safety, can
High, simple to operate, non-maintaining, easy for installation etc. by property, and the advantage of maximum is not affected by external environmental condition, such as solidifying
Dew, filthy, toy and chemical substance etc., can be used on the place of bad environments.Another important feature is, due to usability
The excellent sf6 gas of energy, greatly reduces the overall dimensions of cabinet, is conducive to developing to miniaturization.And sf6 gas-insulated
Ring main unit is because having that non-maintaining, size is little, excellent performance, safe and reliable the features such as, in China, secondary distribution system is got over
More widely to use.
At present, the designed pt cabinet with production of all sf6 gas-insulated ring network cabinet producers is all with middle-placed switch cabinet one both at home and abroad
The principle of sample, its main bus-bar is an exposure in the air, by air insulation.The cabinet width of this structure not only cabinet is relatively wide, and
The interface also ununified to the spelling cabinet between cabinet and cabinet.New sf6 ring main unit pt cabinet cabinet body structure just revises these defects,
Improve cabinet body structure, improve the reliability of product.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of sf6 looped network pt cabinet body structure.
In order to realize object above, this utility model be the technical scheme is that
A kind of sf6 looped network pt cabinet body structure, including main bus-bar gas tank, low-pressure chamber and pt compartment, described main bus-bar gas tank
Be respectively arranged on the left side and the right side n specification identical bus inlet interface and bus outlet interface, be provided with for connecting on the downside of it
N pt connection end of pt isolation room, this n bus inlet interface, n bus outlet interface and n pt connection end correspond
Connect, and be filled with sulfur hexafluoride gas between bus inlet interface, bus outlet interface and pt connection end；Described low-pressure chamber
It is arranged at the front side of main bus-bar gas tank, be provided with observation window in low-pressure chamber front simultaneously.
Further, described low pressure interior is communicated with to main bus-bar gas tank the gas for detecting main bus-bar gas tank internal gas pressure
Pressure table, described barometric dial plate is just to observation window.
Further, also include the cabinet door being arranged at cabinet front, famous brand and electrical primary are provided with this cabinet door simultaneously
Circuit diagram.
Further, the height of its cabinet is 1400mm, and depth is 780mm, and width is 650mm.
The beneficial effects of the utility model are: a kind of sf6 looped network pt cabinet body structure of the present utility model, and its bus inlet wire connects
Mouth and bus outlet interface, all using identical specification, are easy to be attached with other various cabinets in the future.Additionally, bus inlet wire
Be filled with sulfur hexafluoride gas between interface, bus outlet interface and pt connection end, due to sulfur hexafluoride gas have excellent
Insulating properties, therefore greatly reduces the overall dimensions of cabinet, is conducive to developing to miniaturization.
Brief description
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the perspective view of main bus-bar gas tank of the present utility model.
Wherein, 1- main bus-bar gas tank, 11- bus inlet interface, 12- bus outlet interface, 13-pt connection end, 2- low pressure
Room, 21- observation window, 22- air gauge, 3-pt compartment, 4- cabinet door.
Specific embodiment
In conjunction with the drawings and specific embodiments, to this utility model, technical scheme required for protection is made further specifically
Bright.
Referring to shown in accompanying drawing 1 and accompanying drawing 2, a kind of sf6 looped network pt cabinet body structure, the height of its cabinet is 1400mm, depth
For 780mm, width is 650mm.Including main bus-bar gas tank 1, low-pressure chamber 2, pt compartment 3 and the cabinet door 4 being arranged at cabinet front, institute
The main bus-bar gas tank 1 stated be respectively arranged on the left side and the right side n specification identical bus inlet interface 11 and bus outlet interface 12,
It is provided with the n pt connection end 13 for connecting pt isolation room, this n bus inlet interface 11, n bus outlet interface on the downside of it
12 and n pt connection end 13 connect one to one, and bus inlet interface 11, bus outlet interface 12 and pt connection end 13 it
Between be filled with sulfur hexafluoride gas.Described low-pressure chamber 2 is arranged at the front side of main bus-bar gas tank 1, is provided with low-pressure chamber 2 front simultaneously
Observation window 21, described cabinet door 4 is provided with famous brand and electrical primary circuit diagram, and the window frame frame of observation window 21 fastens screw fashion using interior
Carry out blend compounds sealing is installed, can't see installation screw or screw hole from observation window 21 front, do not adopt rubber ring or outside
