Description
Technical field
It is to be related to a kind of secret switch cabinet, more particularly to one specifically the present invention relates to a kind of power distribution cabinet
Sealed high-tension switch cabinet is planted, belongs to technical field of electric equipment.
Background technology
High-tension switch cabinet is to be used to realize in power system generating, transmission of electricity, distribution, electric energy conversion and consumption to play break-make, control
The electric equipment products of the effect such as system or protection.High-voltage switch gear manufacturing industry is the manufacturing important component of power transmission and transforming equipment, whole
Occupy very important status in individual power industry.
Current domestic and international 6~40.5KV high-tension switch cabinet (circuit breaker switch cabinet) mainly has fixed switching cabinet (fixed
Cabinet), middle or withdraw-type switch cabinet (hands injured), inflatable cabinet (gas-filling cabinet) and solid insulation switch cabinet, above-mentioned various height
The cabinet that compresses switch respectively has advantage and disadvantage.
Fixation cabinet is first generation high-tension switch cabinet product, and its cabinet is that internal part use is fixedly connected, simple in construction,
Element is few, good heat dissipation, and busbar connection is reliable, and stability is higher, and cabinet size is smaller and floor space is small;But generation event
Barrier needs Measuring error, because its mode being fixedly connected causes to need whole circuit to need power-off, and dismounting trouble, makes the inspection for fixing cabinet
Repair time length and from causing power off time long, great inconvenience is brought to transmission of electricity electricity consumption.
In order to improve the problem of fixed cabinet is present, handcart switch cabinet have adjusted position of the breaker in cabinet, will be disconnected
Road device and a car body are integrated into a moveable handcart circuit breaker, and breaker portion can be extracted out to cabinet during maintenance, change convenient;
But due to the requirement of clear distance between electric conductor so that the size of hands injured is big compared with fixed cabinet and ancillary insulator is more.According to breaker
Position in cabinet can be divided into middle-placed switch cabinet and remove cabinet;The positioning of circuit breaker cart and locking device are all provided with these switch cubicles
In the bottom of handcart, limited by its own structure, this kind of positioning and locking device apply in general to low current switch cabinet, it is impossible to
Resist larger electric power torque.Because when switch cubicle short circuit current flow reaches 50kA and the above, the electric power of generation is very big,
And the electric power produces the junction in handcart moving contact and switch cabinet static contact.Due to electrodynamic action point away from handcart bottom away from
From larger, therefore opposing floor portion handcart positioner easily produces larger torque, and then easily occurs handcart loose shift, causes
Dynamic and static contact is disengaged.Middle truck cabinet, because a plug is slidably connected unreliable, causes contact heating, and its structure
Poor radiation, often because of accidents such as excessively thermally-induced insulation ag(e)ing, blasts.So existing handcart positioning, locking mode are difficult that satisfaction is opened
Close cabinet high current, the high requirement cut-off.In order to lift stability of the handcart switch cabinet in combined floodgate closed-circuit working, prior art has
The largely improvement on handcart fixed form and device, such as Chinese patent application CN 102983524 discloses a kind of switch cubicle and broken
Road device handcart, including car body, car body head are provided with moving contact, and car body both sides are respectively equipped with location-plate;Location-plate is provided with and hand
The directive wheel that the orbital groove of car positioner is adapted, and experiment position lockhole and working position lockhole with handcart positioner
The elastic locking bar being adapted.Breaker handcart of switch cabinet obtained by positioner disclosed in this application and its application can realize hand
The accurate guiding of car and left and right are spacing, and can meet the strong fix of handcart under diverse location state, can effectively reduce electric power
The opplied moment of generation, and then larger electric power can be overcome;But still the stability same or like with fixed cabinet can not be realized
Energy;In addition the cabinet inner breaker of middle-placed switch cabinet typically uses VS1 or VD4 vacuum circuit breakers, and whether accurate dynamic/static contact contraposition is can not
Monitoring, the structure of contact box to be unfavorable for contact radiating, the easy aging of insulation assembly, generation insulation breakdown discharge accident.
Above two switch cubicle has two shortcomings:Floor space is big and the powered major component in primary circuit is not completely enclosed within
In switch cubicle.The development of the switch cubicle of this two class is also direction mainly according to the two features.In addition, either fixing cabinet also
It is open to be that hands injured is, i.e., switchgear and connection member are directly exposed in air in cabinet, and shell protection grade is low,
It is poor for applicability, it is more sensitive to ambient air quality, it is difficult to which it is filthy to be applicable south China, coastal area and underground condensation
The service condition in harsh place.Simultaneously as provided with heat emission hole or radiator fan, air circulates in power distribution cabinet, easily by ash
Dirt, humid air influence performance, it is easier to cause equipment to aoxidize and the reduction of surface insulation performance, so as to shorten the use longevity of equipment
Life.
Because environment influences this big problem on switch cubicle, a kind of sealed gas-filling cabinet, such as C-GIS subsequently have developed;
The whole cabinet of the switch cubicle, and can be by improving in cabinet pressure to ensure insulating properties to be sealed to being filled with SF6 in cabinet, and can
To reduce cabinet size by reducing insulation clear distance, and degree of protection IP high, solve the problem of ambient influnence is to equipment;But
Still there is gas leak phenomenon, just occur when gas leakage because insulation distance is not enough so that equipment will be unable to normal operation and use and safety
Greatly, accident easily occurs for hidden danger;In addition, because its structural detail and cabinet are integrated, when equipment needs to overhaul or changes
When, it is impossible to realize that detection and maintenance for part or individual elements are changed, make it be only capable of using as disposable power distribution cabinet, tie up
Accomplish this high;Integral replacing also greatly increases power failure range and time, reduces the continuity of power supply;In addition, gas-filling cabinet
Further disadvantage is that the SF6 being filled with cabinet has been listed in greenhouse gases, belong to should emission reduction row, energy-conservation is now carried forward vigorously with China
Emission reduction is runed counter to.
In recent years, the solid insulation switch cabinet newly released, from employing solid insulation mode unlike above-mentioned switch cubicle
Insulated.So-called solid insulation, and its not only sealing vacuum interrupter of each unlike pole, but will go out
Arc chamber and associated part are integrated poured using epoxy resin progress, and it is over the ground so to cause switch internal alternate
Safe insulation distance has shortened to grade from the 125mm of air insulation, although be greatly reduced the dimension volume of switch cubicle;
The switch cubicle environmental protection, is adapted to distribution automation, and environment resistant pollution is strong;But due to forming solid which employs solid insulation mode
Body insulating part, the solid insulation moisture-sensitive aging, insulating properties reduction and can not monitoring and supervising in real time, easily insulate on the contrary
Disruptive discharge accident;Complex manufacturing technology, and the insulating materials of high-performance and good stability is the one big of solid insulation switch cabinet
Difficulty, in addition such switch cubicle equally there is fixed cabinet, breaking down needs Measuring error extremely inconvenient;Domestic enterprise
Also in further research and development, and the expensive cost of external import is high.
At present, above switch cubicle can not meet power system requirement higher and higher to power supply quality and reliability,
Economy, reliability higher and higher requirement of the power system to high-tension switch gear can not be met;Disliked in particular for harsh
The switchgear used under bad environment.
