The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and the small-scale vaccum ring main unit that a kind of volume is little and functional reliability is high is provided.
The technical solution of the utility model is, a kind of small-scale vaccum ring main unit is provided, and comprises housing, spring operating mechanism, arc interrupter pole, tri-station isolating switch, mechanical interlocking assembly and isolated bus; Described tri-station isolating switch, mechanical interlocking assembly and spring operating mechanism are located at the top in the housing; Described tri-station isolating switch, mechanical interlocking assembly, spring operating mechanism connect successively; The operating knob of described tri-station isolating switch is located at outside the housing; Described isolated bus is located at the below of spring operating mechanism, and the upper end of described isolated bus is connected with spring operating mechanism; Described arc interrupter pole is located at the below of tri-station isolating switch in the housing, and described arc interrupter pole is connected on the isolated bus, and the terminals of described isolated bus are located at outside the housing; Described housing is seal casinghousing; Described spring operating mechanism, tri-station isolating switch, mechanical interlocking assembly all are located in the seal casinghousing.
Described housing is provided with the through hole that passes for isolated bus, and described isolated bus outer cover has insulating sleeve, and described insulating sleeve is fixed on the through hole.
Described isolated bus is three, and obliquely 45 ° of directions that described three isolated buses are shell back face-plate are arranged in order.
After adopting above structure, the utility model compared with prior art has the following advantages:
The spring operating mechanism of the utility model small-scale vaccum ring main unit, arc interrupter pole, tri-station isolating switch, mechanical interlocking assembly and isolated bus all are located in the seal casinghousing, because the housing of sealing has been arranged, therefore avoided the generation of filth and condensation, thereby guaranteed the normal operation of small-scale vaccum ring main unit, so that the functional reliability of small-scale vaccum ring main unit is higher.Simultaneously, because the terminals of described isolated bus are located at outside the housing, therefore reduced the volume of vacuum ring main unit.
As improvement, described housing is provided with the through hole that passes for isolated bus, and described isolated bus outer cover has insulating sleeve, and described insulating sleeve is fixed on the through hole.Because insulating sleeve arranged, therefore avoided the possibility of conducting electricity between isolated bus and the housing, thereby so that the functional reliability of small-scale vaccum ring main unit is higher.
As improvement, described isolated bus is three, and obliquely 45 ° of directions that described three isolated buses are shell back face-plate are arranged in order.Thereby effectively reduced the horizontal area occupied of three isolated buses, thereby so that the volume of the utility model small-scale vaccum ring main unit further reduce.
