Description
Technical field
This utility model relates to high-tension distribution equipment field, simply clear convenient to operate particularly to a kind of actuating interface
Ring main unit.
Background technology
Ring main unit is in one group of high-tension switch gear is contained in steel sheet metal cabinet or to make assembled compartment ring network power supply list
The electrical equipment of unit, its core uses on-load switch and fuse, has simple in construction, volume is little, price is low, can improve
Power supply parameter and the advantage such as performance and power supply safety.Looped network refers to ring distribution system, i.e. supply main forms a Guan Bi
Annular, power supply powers to this ring main, from main line another road by the outside distribution of high-voltage switch gear, when left side is done
Line is out of order, and it just continues to be powered from right side main line, and when right side main line is out of order, it just continues from left side main line
Powered, so, although main power is single service, but obtained being similar to double for each distribution branch road
The material benefit that road powers, thus improve the reliability of power supply.Ring main unit is that each distribution branch road sets a switch cubicle (outlet switch
Cabinet), the bus of this switch cubicle is exactly a part for ring main simultaneously.The rated current of ring main unit is all little, thus looped network
The high-voltage switch gear of cabinet does not the most use baroque chopper to take the high voltage load of the band high-tension fuse of simple in construction
Switch.Ring main unit on-load switch operates normal current, and excises short circuit current with fuse, and both combines and instead of
Chopper.Certainly this can only be confined in certain capacity.Such switch cubicle can use the distribution of non-ring network structure the most completely
In system, applying in being as the extensive of this switch cubicle, " ring main unit " has just been jumped out the category of looped network distribution and has been referred to negative
Lotus switch is the high-tension switch cabinet of master switch.
The time that ring main unit occurs is the longest, is but widely used in a variety of applications, this work got up mainly due to new development
The building of industry enterprise and establishment, from the perspective of for distribution, with medium and small capacity for its distribution transformer of great majority
Being usually no more than 1250KVA, power steadily in the long term, high-voltage switch gear infrequently operates.Along with large-scale urban construction, great Liang great
Type high-rise is rised sheer from level ground, and transformer and distribution station is the most just located at downstairs, and according to fire-fighting requirements, distribution equipment must " oil-free
Change ", according to build area reasonable employment, distribution equipment should " miniaturization ", then ring main unit has been put into flickering building.
Ring main unit simple in construction, reliable and safety, maintenance capacity is the least, and operating cost is low, compared with the switch cubicle equipped with chopper, excellent
Gesture is the most prominent.Ring main unit requires that on-load switch has higher performance and less volume, and novel on-load switch arises at the historic moment,
This has driven the technological progress of ring main unit the most in turn, current ring main unit not only function admirable but also seriation, and this more expands
Open up the range of ring main unit.But, ring main unit of the prior art is during using, and it is positioned in charged assembly
Display lamp is usually the color display lamps such as reddish yellow indigo plant, the display situation of color display lamp during the distribution operation carrying out complexity
Sometimes can cause certain confusion to operator, it is impossible to that quickly judges operated step is particularly shown result.
Utility model content
The purpose of this utility model is to provide a kind of ring main unit, and it is the clearest that it has operating mechanism interface, it is simple to operation
The advantage with preferable hommization.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of ring main unit, including electric current display module, switching manipulation assembly and charged display module, described insulation ring main unit
Set gradually from top to bottom as electric current display module, switching manipulation assembly and charged display module, described electric current display module bag
Including display lamp, described display lamp is liquid crystal Chinese character indicator panel.
Being arranged such, during carrying out the distribution operation of complexity, the display situation of display lamp can directly display the knot opened or closed
Really, operator can be allowed to understand the simple and clear present situation understanding operation, that quickly judges operated step is particularly shown knot
Really.
Arrange further: described liquid crystal Chinese character indicator panel is externally provided with lucite housing.
It is arranged such, is outside equipped with machine glass shell at Chinese character indicator panel and on the one hand can play insulation protection display screen
Effect, another aspect is visual due to glass object, the display state of easy-to-read display screen.
Arrange further: described liquid crystal Chinese character indicator panel outer rim is provided with prominent ring, and described lucite housing outer rim is provided with
The recessed ring matched with liquid crystal Chinese character indicator panel outer rim.
Being arranged such, LCDs outer rim is provided with the recessed ring phase interworking that prominent ring is provided with lucite housing outer rim
Close so that lucite housing is dismountable, detachable wiping or replacing when lucite object thickens unclear.
Arrange further: described lucite housing is cuboid housing, and described cuboid housing edges and corners are circular arc.
Being arranged such, it is sharp-pointed in rectangle housing edges and corners to be that circular arc makes operator avoid in operation
Corner angle scratching fingers.
Arrange further: being also arranged with the cabinet of insulation outside described ring main unit, described switching manipulation component cabinet is external to be provided with
The emissive plastic glazing of insulation.
Being arranged such, equipment and peripheral apparatus in having in ring main unit, being externally provided with emissive plastic glazing at cabinet can facilitate
Observing internal setting, the instruction of switch machine position and partition mouth visual, operating mechanism interface is the clearest, it is simple to operation, simultaneously
Door is organically to can be good at insulation, has preferable hommization.
Arrange further: described charged display module cabinet is externally provided with the organic glass door of switchable device.
Being arranged such, equipment and peripheral apparatus in having in ring main unit, being externally provided with organic glass door at cabinet can facilitate
