Description
Technical field
High voltage electric equipment manufacturing field is the utility model is related to, specially a kind of indoor HVAC combined type open circuit
Device.
Background technology
FTK-40.5 vacuum load switch-fuse combined electrical equipments have been produced in enormous quantities and have been molded at present.Especially coordinate
Box type transformer product sells to major new energy project, such as wind-power electricity generation, solar power generation, still, according to the use of product
The information that situation and Market Feedback are returned, when transformer capacity meets or exceeds 2750kVA, it is necessary to using vacuum circuit breaker+every
The combination of pass+earthed switch is left, the connecting-disconnecting function of product is realized by breaker, and is no longer rely on vacuum load switch
Fuse in pass-fuse combined electric apparatus cut-offs.This structure type is for case change, and either cost still makes
Difficulty all greatly promotes, and needs a small volume badly, possesses the substitute products of connecting-disconnecting function to realize.
The content of the invention
In order to make up drawbacks described above, the utility model is on the basis of existing technology, there is provided indoor HVAC combines
Formula breaker, possess the repertoire of " vacuum circuit breaker+disconnecting switch+earthed switch ", form modular product, pass through adjustment
The mechanical property parameter of breaker itself, performance is set to meet electric current 1250A and cut-off 31.5kA ability.
The technical solution of the utility model is：Indoor HVAC modular breaker, it is characterised in that：By metal frame
Frame, spring operating mechanism, vacuum interrupter, disconnecting switch, earthed switch composition, vacuum interrupter pass through wall bushing and insulation
Son is fixed on metal framework, and electric current transmission is realized in vacuum interrupter top by wall bushing and disconnecting switch, passes through insulation
Pull bar is connected realization transmission with spring operating mechanism, is realized between described vacuum interrupter, disconnecting switch, earthed switch three
Chain braking, on the left of combined electrical apparatus, vacuum circuit breaker is combining disconnecting switch in combined electrical apparatus upper right side, high voltage ground switch
Electrical equipment lower right side, disconnecting switch are connected with vacuum circuit breaker, the spring behaviour that vacuum circuit breaker is connected described with high voltage ground switch
Mechanism actuating panel is installed, described actuating panel is provided with order handle hole on motivation structure.
The utility model realizes the matching with existing box type transformer, is not changing the situation of box type transformer size as far as possible
Under, meet the installation when capacity meets or exceeds 2750kVA, increase spring mechanism combined floodgate spring force amount, allow modular breaker
Power source（Spring mechanism）Possess the release force of abundance, offset the operating pressure on vacuum arc-extinguishing chamber contact, it is therefore an objective to be full
The service ability of sufficient rated current and the connecting-disconnecting function of short circuit current, when spring mechanism releases energy, insulated tension pole drives true
The conjunction of empty arc-chutes point, the conjunction point between upper contact head and lower contact is realized, so as to meet the function of breaker folding electric current.
Linkage process of the present utility model is two parts quiescing in addition when vacuum circuit breaker is in closure；When connecing
Earthing knife-switch forbids closing vacuum circuit breaker when closing；Mechanical latching between disconnecting switch and high voltage ground switch.
The switching force that the utility model VTKZ-40.5/T1250-31.5 modular breakers need is bigger, so during design
Need to optimize the component switching-in spring of spring mechanism（Increase spring K values）, it is allowed to meet between upper contact head and lower contact
Contact force；, it is necessary to 1250A rated current be flowed through, so resulting temperature during normal current-carrying work after breaker closing
Vacuum extinction outdoor must be delivered to through electric conductor by rising heat, complete the dissipation of heat.
The utility model not only plays support fixation as the wall bushing being connected with vacuum interrupter to arc-chutes,
Flow conductivity is also equipped with, realizes the electric current transmission between vacuum interrupter and isolation knife, while is also isolation knife support rotating point.
Application of the wall bushing on this breaker has served vital, and breaker height dimension effectively is dropped into ideal
State, the size of decline are left for needed for size when earthing is opened downwards.
The utility model is to each functional unit in this breaker, such as：Between vacuum interrupter, isolation knife, earthing
Action relationships, realize, prevented because maloperation causes the generation of accident in strict accordance with certain operation order.Order operation relies on
The panel of spring mechanism front end realizes, is provided with each order handle hole above, and per hole between mutual linking, it is therefore prevented that maloperation
Generation.
The utility model has the advantage that compared with existing product：The utility model possesses " vacuum circuit breaker+isolation
The repertoire of switch+earthed switch ", modular product is formed, by adjusting the mechanical property parameter of breaker itself, making property
Electric current 1250A can be met and cut-off 31.5kA ability；The utility model is provided with wall bushing, and not only arc-chutes are played with branch
Fixation is supportted, is also equipped with flow conductivity, realizes the electric current transmission between vacuum interrupter and isolation knife, while is also isolation knife
Support rotating point, effectively drops to perfect condition by breaker height dimension, and the size of decline is left earthing for and opened downwards
When size needed for.
