Embodiment
Below in conjunction with specific embodiment the utility model is further set forth.
The high-pressure subsection cabinet of a kind of Mechanically programm interlocking as shown in Figure 1 comprises that cabinet 2 is isolated in section breaker cabinet 1, segmentation and Mechanically programm locks, and is used for bus 3 is divided into two sections operations.
As Fig. 1, shown in Figure 7, section breaker cabinet 1 comprises the isolating switch 13 in the circuit breaker 11, breaker cabinet door 12, section breaker cabinet and is used for the breaker cabinet operating mechanism 14 of isolating switch 13 divide-shut brakes in the control section breaker cabinet, segmentation isolate cabinet 2 comprise isolate cabinet door 21, segmentation is isolated the isolating switch 22 in the cabinet and is used for the isolation cabinet operating mechanism 23 that isolating switch 22 divide-shut brakes in the cabinet are isolated in the control segmentation.
Shown in Fig. 2～6, the model that Mechanically programm lock adopts is DM22, comprises first tapered end 41 for locking breaker cabinet operating mechanism 14, is used for locking and isolates second tapered end 42 of cabinet operating mechanism 23, be used for locking and isolate the 3rd door lock 43 of cabinet door 21, be used for the 4th door lock 44 of locking breaker cabinet door 12 and the key 45 of release first tapered end 41, second tapered end 42, the 3rd door lock 43, the 4th door lock 44 in order.First tapered end 41, second tapered end 42, the 3rd door lock 43, the 4th door lock 44 sort in order, and key 45 needs release in order, or locking in reverse order, otherwise can not operate.
First tapered end 41 is installed in isolates on the cabinet operating mechanism 23, and second tapered end 42 is installed on the breaker cabinet operating mechanism 14, and the 3rd door lock 43 is installed in isolates on the cabinet door 21, and the 4th door lock 44 is installed on the breaker cabinet door 12.
As shown in Figure 7, if the 2# main transformer breaks down, need to drop into the segmentation cabinet and connect two sections buses 3, namely 1# main transformer while power supply buses is 3 two sections, and this need be communicated with segmentation and isolate cabinet 2 and section breaker cabinet 1.During connection (when sending electricity), the isolating switch 13 if section breaker cabinet 1 closes earlier in the section breaker cabinet, after the circuit breaker 11 that closes, this bus does not also have connection for 3 two sections, the isolating switch 22 in the cabinet is isolated in the last segmentation of just closing, and can cause hot line job like this, has violated " five is anti-" regulation; If can come into operation after the reparation of 2# main transformer, need to disconnect the segmentation cabinet, and when needing maintenance section breaker cabinet 1, circuit breaker 11 first separating brakes, the isolating switch 13 in the separating brake section breaker cabinet again forgets that as operating personnel this segmentation of separating brake isolates the isolating switch 13 in cabinet, at this moment position a, position b among Fig. 7, position d place are all charged, c place, position is not charged, and operating personnel have then violated " five is anti-" mistakenly entering charged chamber regulation if directly open 12 maintenance of breaker cabinet door.
The interlocking principle of this segmentation cabinet is as follows:
During power failure, at first the separating brake circuit breaker 11, then with key 45 releases first tapered end 41, isolating switch 13 in operating breaker cabinet operating mechanism 14 and the separating brake section breaker cabinet, relock first tapered end 41 then, take out key 45, use key 45 releases second tapered end 42 again, operation is isolated cabinet operating mechanism 23 and the interior isolating switch 22 of separating brake segmentation isolation cabinet, relocks second tapered end 42 then, take out key 45, at this moment the position a among Fig. 7, b place, position is not charged, is equivalent to segmentation and isolates in the cabinet 2, not charged in the section breaker cabinet 1, then with key 45 releases the 3rd door lock 43, open and isolate cabinet cabinet door 21, take out key 45, use key 45 releases the 4th door lock 44 at last, open breaker cabinet door 12, at this moment key 45 is stayed on the 4th door lock 44, but safety inspection segmentation cabinet.
When sending the electricity operation, elder generation's shutdown device cabinet door 12, lock the 4th door lock 44, take out key 45, close again and isolate cabinet door 21, lock the 3rd door lock 43, take out key 45, then with key 45 releases second tapered end 42, operation is isolated cabinet operating mechanism 23 and the interior isolating switch 22 of segmentation isolation cabinet that closes, and relocks second tapered end 42 again, takes out key 45, then with key 45 releases first tapered end 41, operating breaker cabinet operating mechanism 14 and isolating switch 13 in the section breaker cabinet that closes relocks first tapered end 41 again, and take out key 45, the circuit breaker 11 that closes a floodgate at last send electricity to finish.
Execution mode of the present utility model is not limited thereto, according to foregoing, ordinary skill knowledge and customary means according to this area, do not breaking away under the above-mentioned basic fundamental thought of the utility model prerequisite, equivalent modifications, replacement or change that the utility model can also be made other various ways all can realize the utility model purpose.
