The invention relates to a switchgear of a 12 kV generator circuit breaker. The switchgear comprises an independent cable chamber, an independent bus chamber, an independent instrument chamber and an independent circuit breaker chamber. The instrument chamber is located on the front upper part of a cabinet, the bus chamber is located on the rear upper part of the cabinet, the cable chamber is located on the rear lower part of the cabinet, the vacuum circuit breaker is installed in the circuit breaker chamber, an insulator is installed in the cable chamber, and a main busbar and a disconnecting switch are installed in the bus chamber. A horizontal rotating shaft is arranged in the cabinet, the front end of the horizontal rotating shaft extends to the front part of the cabinet, the rear end of the horizontal rotating shaft extends to the rear part of the cabinet, a connecting lever is arranged on the horizontal rotating shaft, the two ends of a perpendicular pull rod are connected with the connecting lever and the disconnecting switch respectively, and a disconnecting switch operation hole is formed in a front door of the cabinet. The switchgear is provided with the four independent chambers, components are reasonably and compactly arranged, and operation is safe; the disconnecting switch is switched off and on in a horizontal rotating shaft and perpendicular pull rod combined moving mode, the dimension of the cabinet is reduced, and the on-off operation of the disconnecting switch is convenient to operate with less effort.
Description
technical field [0001] The invention relates to the technical field of electrical control equipment, in particular to a switchgear for a circuit breaker at the outlet of a 12kV generator. Background technique [0002] The 12kV generator outlet circuit breaker switchgear plays an important role in the system as a protection device for the generator circuit. However, due to the large rated current of the generator circuit, when a short-circuit fault occurs, the switchgear needs to break the maximum short-circuit current of 63kA. Compared with conventional switchgear, generator outlet switchgear has special technical requirements in terms of cabinet structure, convenient operation, and safe use. Contents of the invention [0003] The invention aims to provide a switchgear for a circuit breaker at the outlet of a 12kV generator, which has scientific and reasonable structure, convenient operation and safe use. [0004] In order to achieve the above object, the technical schem...
