The small-scale vaccum ring main unit of prior art 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 housing; Described tri-station isolating switch is located at the one end near guidance panel, described spring operating mechanism is located at the one end away from guidance panel, described mechanical interlocking assembly is located between tri-station isolating switch and spring operating mechanism, the incoming end of described mechanical chain assembly is connected with tri-station isolating switch, and the end that picks out of described mechanical chain assembly is connected with spring operating mechanism; The operating knob of described tri-station isolating switch is located at outside housing; Described isolated bus is located at the below of housing inner 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 housing, and described arc interrupter pole is connected on isolated bus.There is following defect in the small-scale vaccum ring main unit of said structure: because spring operating mechanism, arc interrupter pole, tri-station isolating switch, mechanical interlocking assembly and isolated bus are all located in housing in the use procedure of reality, therefore the volume of small-scale vaccum ring main unit is not only increased, and small-scale vaccum ring main unit is arranged in field, because housing does not seal, therefore be easy to produce the problems such as filth, condensation, thus affect the normal work of small-scale vaccum ring main unit.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defect of above prior art, provides a kind of volume little and the small-scale vaccum ring main unit that functional reliability is high.
Technical scheme of the present invention is, provides a kind of small-scale vaccum ring main unit, 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 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 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 housing, and described arc interrupter pole is connected on isolated bus, and the terminals of described isolated bus are located at outside housing; Described housing is seal casinghousing; Described spring operating mechanism, tri-station isolating switch, mechanical interlocking assembly are all located in seal casinghousing.
Described housing is provided with the through hole passed for isolated bus, and described isolated bus outer cover has insulating sleeve, and described insulating sleeve is fixed on through hole.
Described isolated bus is three, and three described isolated buses are that 45 ° of directions obliquely of shell back face-plate are arranged in order.
After adopting above structure, the present invention compared with prior art, has the following advantages:
The spring operating mechanism of small-scale vaccum ring main unit of the present invention, arc interrupter pole, tri-station isolating switch, mechanical interlocking assembly and isolated bus are all located in seal casinghousing, due to the housing having sealing, therefore the generation of filth and condensation is avoided, thus ensure that the normal work of small-scale vaccum ring main unit, make the functional reliability of small-scale vaccum ring main unit higher.Meanwhile, the terminals due to described isolated bus are located at outside housing, because this reducing the volume of vacuum ring main unit.
As improvement, described housing is provided with the through hole passed for isolated bus, and described isolated bus outer cover has insulating sleeve, and described insulating sleeve is fixed on through hole.Owing to there being insulating sleeve, therefore avoid the possibility of conducting electricity between isolated bus and housing, thus make the functional reliability of small-scale vaccum ring main unit higher.
As improvement, described isolated bus is three, and three described isolated buses are that 45 ° of directions obliquely of shell back face-plate are arranged in order.Thus effectively reduce the horizontal area occupied of three isolated buses, thus the volume of small-scale vaccum ring main unit of the present invention is reduced further.
