As shown in figure 3, the operation principle of the compact bus contact cabinet is：Right busbar room bus 333, right three-station
334th, disrance sleeve 335, copper pipe 322, breaker 323 constitute the function of bus contact or segmentation on breaker, by bus from
Switch cubicle bottom is guided at the top of switch cubicle；Copper pipe 324 under breaker, current transformer 325, copper pipe 326 on the left of current transformer,
Disrance sleeve 315, left three-station 314, left busbar room bus 313 constitute bus enhanced feature, by bus from switch cubicle
Bottom lifting is arrived at the top of switch cubicle.
The operation order of compact bus contact cabinet is：When carrying out bus contact operation, first by right three-station
334th, left three-station 314 carries out isolation combined floodgate, then by breaker closing, realizes the left side of left busbar room bus casing 312
Bus and the right side bus contact of right busbar room bus casing 332；When carrying out bus section operation, first by breaker open operation, then
Right three-station 334, left three-station 314 are subjected to isolation separating brake, left busbar room bus 333 and right busbar room is realized
Bus 313 is segmented.
As shown in figure 3, the advantage of the utility model compact bus contact cabinet is：
1) two bus-bar rooms are that left and right is arranged and shares a breaker chamber, and a switch cubicle is left busbar to can be achieved and right
The contact or segmentation of bus and enhanced feature；
2) left busbar, right busbar and right shell keep appropriate insulation distance, rather than from left to right run through whole bus
Room, saves busbar, bus casing so that bus-bar room is compact；
3) left and right bus-bar room is all in the front portion of switch cubicle, in whole transformer station, and the bus-bar room of entire row switch cubicle is all arranged
In the front portion of switch cubicle, the depth dimensions of switch cubicle is reduced, transformer station's floor space is saved.
Although disclosing preferred embodiment of the present utility model and accompanying drawing for the purpose of illustration, skilled
Personnel, do not depart from the utility model and appended spirit and scope by the claims in, can make it is various replace, change and moisten
