Abstract
The invention discloses an economic ring main unit gas cabinet with the reduced size. The gas cabinet comprises a cabinet body, a unit incoming mechanism arranged at the outer side of the cabinet body, an explosion-proof value arranged at the bottom of the cabinet body, an arc-extinguishing cover mounting support seat, a bus support element, a contact support element, a contact transmission mechanism, a load switch, a three-phase unit main bus bar, and a plurality of insulators, wherein the arc-extinguishing cover mounting support seat, the bus support element, the contact support element, the contact transmission mechanism, the load switch, the three-phase unit main bus bar, and the plurality of insulators are arranged inside the cabinet body. The three-phase unit main bus bar is arranged on the bus support element; the contact transmission mechanism is arranged on the contact support element; and a switch structural element of the load switch is assembled to form a cylinder. According to the ring main unit gas cabinet provided by the invention, the internal structural element dimensions of the switch are reduced and the motion travel is optimized. Three kinds of stations operate successively in the range of the cylinder, so that the space is saved. The parts of structural elements are adjusted to be unsaturated epoxy resin materials, so that the insulation performance that can not be realized by metallic materials due to space saving can be realized. And on the basis of the common cabinet design, the space is reduced further.

Contact supporter, contact transmission mechanism, on-load switch, the main busbar of three phase units and some insulators, described three phase units master
Busbar is arranged on bus-bar supporting piece, and described contact transmission mechanism is arranged on contact supporter, the switch of described on-load switch
Structural member is assembled to form cylindrical structure, and switch all enters in conjunction position, point position and earthing position corresponding knife contact in cylinder body
Row conversion.
As present invention further optimization scheme, described bus-bar supporting piece, contact supporter, contact transmission mechanism and go out
The material of arc cover erection support is all using unsatured epoxy resin.
As present invention further optimization scheme, described ring main unit gas tank integrally carries out cotype design, will be a plurality of
Construction of switch is installed in a gas tank.
As present invention further optimization scheme, described insulator includes inner cone -6PCS insulator and 202-3PCS is exhausted
Edge.
The present invention adopts above technical scheme compared with prior art, has following technique effect：
The present invention has more adapted to transform the needs of condition using the ring main unit of small size, transforms for whole distribution and saves
Cost, there is provided more select.Reduce switch internal structural member size and optimize actuating length, by 3 kinds of stations at one
Operate successively in cylindrical scope, therefore save on space；Section structural is adjusted to unsatured epoxy resin material, thus
Solve the unappeasable insulating properties of metal material brought because of save space；Using common box type design, reduce space further.

Specific embodiment
Embodiments of the present invention are described below in detail, the example of described embodiment is shown in the drawings, wherein ad initio
To the element that same or similar label represents same or similar element or has same or like function eventually.Below by ginseng
The embodiment examining Description of Drawings is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
Below in conjunction with the accompanying drawings technical scheme is described in further detail：
Fig. 2 is the overall schematic of shrunk type switching device, and the construction of switch of internal component and whole casing connects and shows
It is intended to as shown in Figure 1：The economical ring main unit gas tank reducing volume disclosed in this invention, including casing, also includes being arranged at
Unit wire inlet mechanism outside casing, it is arranged at the explosion-proof valve of bottom half, and is arranged at the arc-extinguish chamber of box house and install
Bearing, bus-bar supporting piece, contact supporter, contact transmission mechanism, on-load switch, the main busbar of three phase units and some insulation
Son, the main busbar of described three phase units is arranged on bus-bar supporting piece, and described contact transmission mechanism is arranged on contact supporter, institute
The construction of switch part stating on-load switch is assembled to form cylindrical structure, and switch is closing position, dividing position and the corresponding knife of earthing position to touch
Head is all changed in cylinder body.
In one particular embodiment of the present invention, described insulator includes inner cone -6PCS insulator and 202-3PCS is exhausted
Edge.
First from internal structure：The volume overall for reducing equipment, internal structure need to reduce each as far as possible and join
The volume of part, and each construction of switch part is assembled to form a similar cylindrical structure, so switch is closing position, is dividing
Position and earthing position, its corresponding knife contact is all to be changed in cylinder body, thus reducing the stroke space of surrounding, is
