Feeder line cabinet drawout breaker has double break mouth, double space during disjunction, can add the padlock locking in addition, extracts circuit breaker out and has with compound protection or intelligent controlled function, can select according to cable capacity; Dark 800mm before and after the feeder line cabinet, the two sides, front and back is all operating surface, can install on the two sides and extract circuit breaker out, and a feeder line cabinet can be installed 6 630A and extract circuit breaker out, allots 6 times 630A and allots line.
The following front portion of contact cabinet is measuring instrument and table of merit rating, and the rear portion headspace can be installed compensation condenser as required.
Usually bus-bar room is established on switch cubicle top, the cable vault is established in the cabinet bottom, and framework universal circuit breaker chamber, compensation condenser chamber, control room, extraction breaker chamber etc. are established in other position, and special-purpose door is established in each chamber; In the cabinet, bus and bus, between bus and the vertical bus, lap-joint all adopts the sealing of isolated bus box.
Compared with prior art, the utility model has the advantages that:
1) have the unit cabinet and allot line characteristics capacious, thus switchgear house in compact area occupied little, reduce cost, be that GCS, GCK, MNS type switch cubicle (settling fixed switch) are incomparable.
2) in place from the spare space to the run location accurately electric contact is good for drawout breaker, and operation needn't have a power failure, laborsaving, and increase-volume or inspection switch only need be changed switch main body and get final product, and effectively prevent false switching, the safety height; Be specially adapted to renovating of old substation equipment, line and newly-built substation are expanded in increase-volume.
When 3) opening certain compartment door in the cabinet, can not touch electrified body in other compartment, safety; And help whole and each the functional compartments ventilation and heat of cabinet.
4) every outlet wiring all concentrates on the subjacent cable chamber, the mode of connection like this, and the reliability height, easy and safe to operate.
5) the capacitor switching adopts dual system, circuit contacts device and reverse-blocking tetrode thyristor to work in coordination, and improves the operation power consumption of reliability and reduction electronic switch; The compensation instrument apparatus is monitor voltage simultaneously, electric current, and active power, reactive power and conveying signal replace special-purpose distribution monitoring device, reduce cost.
