Description
Technical field
This utility model belongs to power equipment, specifically about a kind of switch cubicle. This utility model is applicable to 12kV, 24kV three-phase alternating current 50/60Hz power system.
Background technology
All-insulated switch cabinet, in 12kV, 24kV three-phase alternating current 50/60Hz power system, as accepting, distribute electric energy and circuit being carried out control, protection, detection. Its structure is generally by arranging bus-bar room, switch gear room, cable vault, control room in cabinet, bus-bar room has bus and branch bar, high pressure inlet wire is connected by bus with on-load switch upper contact head, high-voltage terminal is connected by branch bar with contact under on-load switch, branch bar is installed current transformer, sensor and earthed switch, switchs indoor location on-load switch. On-load switch and earthed switch can by operating mechanism Non-follow control. Being used in the switch cubicle in three-phase alternating current Force system, horizontally arranged switch module three groups identical in cabinet, its lateral dimension is big, installs floor space big.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, it is provided that a kind of lateral dimension is little, installs the vertical-type all-insulated switch cabinet that floor space is little.
The technical solution of the utility model includes cabinet, main bus-bar, branch's busbar, on-load switch, fuse, current transformer, sensor, earthed switch, operating-controlling mechanism and cable vault; Mainly main bus-bar, branch's busbar, on-load switch, fuse, earthed switch are encapsulated in sulfur hexafluoride rustless steel gas tank, sulfur hexafluoride rustless steel gas tank is fixedly mounted on the top of cabinet inner cable room, and operating-controlling mechanism is arranged on outside sulfur hexafluoride rustless steel gas tank; On-load switch includes two service entrance switch and an outlet switch, the static contact of two service entrance switch is connected by main bus-bar with outlet switch static contact, the moving contact of two service entrance switch is connected with the cable in cable vault respectively through branch's busbar, and the moving contact of outlet switch is connected with one end of fuse by branch's busbar; Two service entrance switch and outlet switch adopt that upper, middle and lower-ranking is arranged vertically to be arranged in sulfur hexafluoride rustless steel gas tank, and fuse is arranged on the upside of on-load switch, and earthed switch is arranged in the sulfur hexafluoride rustless steel gas tank on the upside of fuse.
Preferably, current transformer adopts open-type transformer, is directly installed on cable, and cable adopts plug-in silicone rubber adapter to connect.
The utility model has the advantages that main bus-bar, branch's busbar, on-load switch, fuse, earthed switch adopt arranged vertically being encapsulated in sulfur hexafluoride rustless steel gas tank, reduce the lateral dimension of product, floor space is installed little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 cabinet, 2 sulfur hexafluoride rustless steel gas tanks, 3 service entrance switch, 4 outlet switchs, 5 operating-controlling mechanisms, 6 fuses, 7 earthed switches, 8 cable vaults, 9 cables, 10 current transformers, 11 ground connection busbars.
Detailed description of the invention
Vertical-type all-insulated switch cabinet as shown in Figure 1, including cabinet 1, main bus-bar, branch's busbar, on-load switch, fuse 6, current transformer 10, sensor, earthed switch 7, operating-controlling mechanism 5 and cable vault 8; Main bus-bar, branch's busbar, on-load switch, fuse 6, earthed switch 7 are encapsulated in sulfur hexafluoride rustless steel gas tank 2, sulfur hexafluoride rustless steel gas tank 2 is fixedly mounted on the top of cabinet 1 inner cable room 8, sulfur hexafluoride rustless steel gas tank 2 inner chamber fills the sulfur hexafluoride gas of 0.04Mpa air pressure, improve the insulating properties between each parts, sulfur hexafluoride rustless steel gas tank 2 adopts that corrosion resistant plate is hermetically sealed to be welded, degree of protection reaches IP67, and operating-controlling mechanism 5 is arranged on outside sulfur hexafluoride rustless steel gas tank 2; On-load switch includes two service entrance switch 3 and an outlet switch 4, the static contact of two service entrance switch 3 and outlet switch 4 static contact are linked together by main bus-bar, the moving contact of two service entrance switch 3 is connected with the cable 9 in cable vault 8 respectively through branch's busbar, the moving contact of outlet switch 4 is connected with one end of fuse 6 by branch's busbar, and the other end of fuse 6 is connected with cable 3 by branch's busbar; Two service entrance switch 3 and an outlet switch 4 adopt that upper, middle and lower-ranking is arranged vertically to be arranged in sulfur hexafluoride rustless steel gas tank 2, and fuse 6 is arranged on the upside of on-load switch, and earthed switch 7 is arranged in the sulfur hexafluoride rustless steel gas tank 2 on the upside of fuse 6. This mounting structure adds the height of cabinet 1, reduces the width of cabinet 1, reduces the installation floor space of cabinet 1.
Current transformer 10 adopts open-type transformer, is directly installed on cable 9, and cable 9 adopts plug-in silicone rubber adapter to connect. Ground connection busbar 11 is installed bottom sulfur hexafluoride rustless steel gas tank 2, it is ensured that equipment reliable ground.
