Description
Technical field
This utility model is related to switch cabinet equipment technical field, more specifically, more particularly, to a kind of ac high-voltage metal
Closed loop-network switch cabinet.
Background technology
AC high-voltage metal sealed formula loop-network switch cabinet is that current China uses a kind of most switch cubicles, main in switch cubicle
Pressure-operated load switch to be adopted, vacuum type on-load switch, air insulation on-load switch, on-load switch fuse packet type switch
Composition.Existing on-load switch typically adopts on-load switch+fuse combined electric apparatus to provide in the protected mode of distribution transformer
Protection, on-load switch can safely division rated load current；The limiting fuse of high rupturing capacity can cut-off short circuit electricity
Stream, both is exactly organically combined it is possible to meet exchanging electricity transformer in various normal and fault by on-load switch
The requirement of protection under the method for operation.But, when on-load switch division load current in combined electrical apparatus, fuse cut-offs short circuit electricity
Stream, has the region of an overcurrent, because high rupturing capacity current limliting Container does not have any behaviour between both electric currents
Make mechanism and control loop, take the protected mode that lacuna phase is run completely, this can cause electrical network phase shortage, and under-voltage phenomenon is sent out
Raw.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of easy for installation, flexible operation,
Interlock reliable AC high-voltage metal sealed formula loop-network switch cabinet.
For achieving the above object, the technical solution adopted in the utility model is：A kind of AC high-voltage metal sealed formula looped network
Switch cubicle, including cabinet, is separated into bus-bar room, control room, little bus-bar room and cable vault by metal partion (metp) inside described cabinet, its
In, bus-bar room, control room and little bus-bar room are located at the top of cabinet, and cable vault is located at the bottom of cabinet, and described cable vault is built-in
There are spark gap, insulator and earthing, be connected by copper bar between described insulator and earthing；Described cable vault and bus-bar room
Between within the chamber equipped with the vacuum circuit breaker summation current transformer being interconnected by copper bar；Described bus-bar room is built with isolation
Switch, described disconnecting switch is connected with vacuum circuit breaker by copper bar；The lower section of described control room is equipped with isolation interlocking mechanism, institute
State isolation interlocking mechanism include interlocking mechanism's latch plate of being contained in cabinet door and be arranged on latch plate rear end respectively with disconnecting switch

With new any restriction.
As depicted in figs. 1 and 2, a kind of AC high-voltage metal sealed formula loop-network switch cabinet that this utility model provides, including
Cabinet 1, is separated into bus-bar room 11, control room 12, little bus-bar room 13 and cable vault 14 by metal partion (metp) inside described cabinet 1, its
In, bus-bar room 11, control room 12 and little bus-bar room 13 are located at the top of cabinet 1, and cable vault 14 is located at the bottom of cabinet 1.
Described cable vault 14 is built with spark gap 2, insulator 3 and earthing 4, logical between described insulator 3 and earthing 4
Cross copper bar to connect；Within the chamber between described cable vault 14 and bus-bar room 11 is equipped with the vacuum circuit breaker being interconnected by copper bar
5 summation current transformers 6；Described bus-bar room 11 passes through copper bar and vacuum circuit breaker 5 built with disconnecting switch 7, described disconnecting switch 7
Connect；The lower section of described control room 12 includes, equipped with isolation interlocking mechanism 8, described isolation interlocking mechanism 8, the connection being contained in cabinet door
Latch mechanism latch plate 81 and be arranged on the upper isolation that latch plate 81 rear end is connected respectively with disconnecting switch 7 and vacuum circuit breaker 5 even
Bar 82 and lower spacer link 83, by operation interlocking mechanism latch plate 81, can drive spacer link 82 so that disconnecting switch 7 is moved
Make, during due to disconnecting switch operation 7, vacuum circuit breaker 5 necessarily be in gate-dividing state, if vacuum circuit breaker 5 does not have separating brake,
Directly vacuum circuit breaker 5 is adjusted by lower spacer link 83 by operation interlocking mechanism latch plate 81, is allowed to be in separating brake
State.
