Assembled interval type ring main unit

Abstract

The invention discloses an assembled interval type ring main unit. The ring main unit comprises a ring main unit body, a detachable base cylinder is installed on the left side of the ring main unit body, racks are slidably arranged on the inner walls of the front side and the rear side of the base cylinder respectively, a gear rotationally arranged on the inner wall of the base cylinder is arranged between the two racks, and the two racks are matched with the gear respectively. Insertion plates are fixedly connected to one ends, away from the gears, of the racks, and detachable sleeves are installed at the positions, corresponding to the two insertion plates, of the right side of the ring main unit respectively. The ring main unit has the advantages that the two racks can be driven to move in the direction away from each other by rotating a rotary knob, and then the insertion plates can be driven to be inserted into the sleeves in a matched mode, so that splicing of two adjacent ring main units is achieved, operation is very convenient, the interval between the spliced ring main units is reduced, space waste is avoided, and the ring main units can be placed more stably; and when the two adjacent ring main units are disassembled, the knob is directly and reversely rotated.

Description

technical field [0001] The invention relates to the technical field of ring network cabinets, in particular to an assembled interval ring network cabinet. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has a structure It is simple, small in size, low in price, can improve power supply parameters and performance, and power supply security. It is widely used in distribution stations and box-type substations in urban residential quarters, high-rise buildings, large public buildings, and factories and enterprises. . The ring network refers to the ring distribution network, that is, the main power supply line forms a closed ring, the power supply supplies power to the ring main line, and then distributes power from the...

Problems solved by technology

[0003] At present, the ring network cabinets on the market cannot realize the splicing between multiple ring network cabinets when they are in use, so that there is a waste of space when the ring network cabinets are placed, and the disconnection between multiple ring network cabinets makes the ring network cabinets Insufficient installation stability
