Description
Technical field
The utility model relates to circuit breaker switch cabinet technical field, specially a kind of 10kV inflatable demarcation circuit breaker switch
Mechanical interlocks is isolated on cabinet.
Background technique
High-voltage switch cabinet mechanical interlocking is between the operating position of high-tension switch cabinet with the machinery for conditioning each other and linking
Mechanism reaches the locking requirement successively acted, single cabinet mechanical interlocking in operation without using auxiliary operations such as keys,
The correct progress with operation order may be implemented, automatically unlock step by step.When maloperation occurs, automatic blocking may be implemented,
Prevent the progress of maloperation." mechanical interlocking " of high-tension switch cabinet is to ensure that equipment and personal safety, prevents the important of maloperation
Measure.It makes explicit provisions in " 3~35kV ac metal closing switch gear " GB3906 to this, this national standard is " interlocking "
Description are as follows: " metal-enclosed type switchgear, which should include, to be prevented on-load point, close disconnecting switch (stab contact)；Prevent mistake from dividing,
Falsely close circuit breaker, on-load switch, contactor (allowing indicative)；Closed when earthing switch being prevented to be in closed position breaker,
The switch such as on-load switch；Earthing switch is accidentally closed when preventing from charging again；Prevent the accidentally functions such as people's electrification compartment ", above-mentioned five prevent
The content of electric misoperation, referred to as " five is anti-".
10kV inflatable (SF6) high-tension switch cabinet three big switch element generally use: upper isolation method.I.e. disconnecting switch,
Breaker, earthing switch are from top to bottom successively laid out in closing gas tank；Lower isolation method.That is breaker, disconnecting switch, ground connection
It opens and is successively laid out in closing gas tank.But no matter three big switch elements are using in upper isolation method or lower isolation method closing gas tank
Layout.It send power operation sequence to be the same.Power transmission disconnects earthing switch, closes disconnecting switch, close breaker；It is disconnected
Electricity, cut-off breaker disconnect disconnecting switch, close earthing switch.It is not operated by this normal operating procedure, mechanical interlocks meeting
Apply protection, it is ensured that personal safety.
Current 10kV inflatable demarcation circuit breaker cabinet is directly to have borrowed traditional gas-filling cabinet V cabinet, disconnected using its vacuum
The boundary function of road device switch protection relay triggering tripping, protection transformer are injury-free.But traditional gas-filling cabinet V cabinet due to
It is limited by cabinet body 325mm width, what is taken is the arrangement of breaker, disconnecting switch, earthing switch from top to bottom, therefore, raw
A kind of cabinet type is isolated in business men under can only providing a user.It is some to get used to using upper isolation method user, biography has been borrowed in use
When the lower isolation method 10kV inflatable demarcation circuit breaker cabinet of the gas-filling cabinet V cabinet of system, feel panel arrangement and operate it is awkward,
It is required that providing upper isolation method 10kV inflatable demarcation circuit breaker cabinet.
10kV inflatable demarcation circuit breaker cabinet is because there is attached case, and cabinet body width increases one times, and three big switch elements are sealing
Position in case of holding one's breath can arbitrarily arrange that being changed to isolation method does not have difficulty.The main content that changes is: disconnecting switch and open circuit
Device switch, isolator operating mechanism and killer switch operating mechanism are all made of horizontally disposed, independent earthing switch arrangement
Below disconnecting switch and killer switch.
But bringing new problem is: isolation method is descended originally, above and below circuit breaker operation mechanism and isolator operating mechanism
When arrangement, mechanical interlocks between the two is respectively leant out by circuit breaker operation mechanism and the opposite place of isolator operating mechanism
One section of connecting plate, both ends connecting plate overlap joint fastened by screw are connected.Now, isolator operating mechanism and killer switch behaviour
Be all made of as mechanism it is horizontally disposed, it is original respectively to lean out one section of connecting plate and play isolator operating mechanism and disconnected
The effective connection function of road device switch operating mechanism, i.e. isolator operating mechanism prevent combined floodgate interlock from failing；Further, since
Isolator operating mechanism and killer switch operating mechanism installation site change, and isolating switch mechanism manual operation hole exists
For interlocking baffle of the breaker mechanism in "on" position also at discommodity, i.e. isolating switch mechanism prevents separating brake interlocking dress
It sets.And modify mechanical interlock mechanism itself, it is necessary to the cooperation of mechanical interlock mechanism manufacturer is obtained, it is therefore, original not changing
On the basis of isolator operating mechanism and killer switch operating mechanism, a kind of easy connection type is found, realizes disconnecting switch
The interlock of operating mechanism and killer switch operating mechanism between the two seems very necessary.
