Abstract
The utility model discloses an RMU (ring main unit), which relates to a control device in electrical system, comprising an operating mechanism in the RMU, and the RMU is in a cuboid shape, and the inside of the RMU is provided with a control plate, and the control plate is provided with a handle and a wiring end, and the upper layer of the RMU is provided with a movable upper seal door, a left seal door and a right seal door. In the utility model, a handle switch and the wiring end are arranged at the control plate in an integrating way, the utility model is specifically designed for outdoor running, the structure is simple, the maintenance is convenient; secondly, the RMU adopts a full-sealed total box-type structure, the inner layer is not provided with a separator, therefore, the insulation is more reliable, the using is safer; additionally, the operating mechanism is sealed in the RMU, and is free from outside influence, and is totally maintenance-free, therefore, the weatherability of the RMU is good, and the RMU is less affected by environmental factors.
Description
Technical field
The utility model relates to a kind of control appliance that is used for electrical system, a kind of specifically ring main unit.
Background technology
At present, ring main unit has mainly played the function of branch, segmentation and contact in distribution system, has therefore obtained using widely in the cable net transformation of ground, city.Existing employed ring main unit mainly contains shortcoming: 1, ring main unit mostly is the indoor type ring main unit greatly and installs an outer cover transformation additional, and profile is flexible, but has obvious defects, and it is bad to be mainly insulating properties, and weatherability is poor, and is affected by environment bigger; 2, the ring main unit volume is bigger, and complex structure, installation and maintenance expense are higher.Therefore, because the unreasonable factor of ring main unit design itself has caused its result of use and poor-performing.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of insulation property ring main unit preferably, and it is simple in structure, security performance good.
The utility model is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is: a kind of ring main unit, comprise the operating mechanism in the ring main unit, in ring main unit, be provided with control board, on control board, be provided with handle and terminals, be provided with mobilizable seal door above on the upper strata of ring main unit, and be provided with pole I in the both sides of seal door above lower end, be provided with seal door on the left and seal door on the right at the front end of ring main unit, and be provided with pole II at the downside of seal door on the left and seal door on the right.
Pole I described in the utility model is connected with the inwall of ring main unit by connector I, and described connector I is provided with rail groove.
Pole II described in the utility model is connected with the base of ring main unit by connector II, and the two ends of described connector II are provided with jack.
The beneficial effects of the utility model are:
1, bat-handle switch and terminals integrated design aim at outdoor operation design on control board, and be simple in structure, easy to maintenance.
2, ring main unit adopts hermetically sealed common box type structure, and internal layer does not have dividing plate, and it is more reliable, safe in utilization to insulate.
3, operating mechanism is sealed in the case, is not subjected to ectocine, and is non-maintaining fully, therefore, good weatherability, factor affected by environment is less.
