Abstract
The invention discloses an air box type voltage transformer cabinet with a three-position partition switch, which comprises an operation mechanism chamber, a voltage transformer chamber, a voltage releasing chamber, a cabinet body capable of a partition switch, a voltage transformer, and an interlocking operation mechanism, wherein the cabinet body is provided with a sealed air box, the partition switch is a three-position partition switch, the fixed contact end of the three-position partition switch and a joint in a three-phase lead outlet bushing are connected inside the air body by a current conducting rod, and the joint in the three-phase lead outlet bushing is connected to the voltage transformer in the voltage transformer chamber by a high-voltage cable. The air box type voltage transformer cabinet disclosed by the invention can solve the problems that the existing voltage transformer cabinet is not completely insulated and sealed, the unit generality is poor, and the volume of the unite is large.
Description
Technical field
The present invention relates to high voltage electric equipment manufacturing technology field, specifically a kind of voltage transformer cabinet.
Technical background
Current; Voltage transformer cabinet in the sulfur hexafluoride gas-insulating ring main unit in the 12kV/24kV distribution system; (patent announcement day is 2011.01.12 to be called " railway 10KV distribution is used PT " just like name; The license notification number is CN 201708443 U) this voltage transformer cabinet comprises that fuse, voltage transformer and the isolating switch be located in the cabinet are rotary double break mouth isolating switch; It connects voltage transformer through fuse, and connects the Qianmen through mechanical interlock mechanism, offers inspection hole on the Qianmen.The main bus bar of these voltage transformer cabinets and to receive voltage transformer cabinet bus be not to seal fully and all insulation, isolating switch is not three stations, and volume is bigger, and the versatility of unit is not good.
Summary of the invention
Problem to be solved by this invention provides a kind of gas tank formula voltage transformer cabinet with tri-station isolating switch, and it is non-full-insulated full-sealed that it can solve existing voltage transformer cabinet, the not good and bulky problem of the versatility of unit.
To achieve these goals, technical scheme of the present invention is; The gas tank formula voltage transformer cabinet of this band tri-station isolating switch; Comprise the cabinet that is provided with operating mechanism chamber, voltage transformer chamber and pressure releasing chamber and isolating switch; Be contained in the voltage transformer of said transformer indoor; Be contained in the interlocking operating mechanism of the said isolating switch of the indoor connection of said operating mechanism; On said cabinet, also be equipped with and include the sealing gas tank that bus joins seat and said isolating switch, said isolating switch is a tri-station isolating switch, and its fixed contact end is connected in the inside of said gas tank with the female union of three-phase lead collar is set with insulating barrier through outer surface contact rod; In said transformer indoor; The preceding plug-in cable joint and the said three-phase lead collar female union that are socketed in cable one end are pegged graft; The other end of said cable is connected to the said voltage transformer that is installed in above the voltage transformer mounting panel through the voltage transformer joint, and said voltage transformer mounting panel is installed on the cabinet.
Owing to adopted such scheme, the present invention compared with prior art has following beneficial effect:
1, isolating switch is made up of tri-station isolating switch, can realize " closing ", three functions of " branch " " ground connection ", and the function than common isolating switch has been Duoed ground connection can reach security maintenance to keeping in repair after the voltage transformer ground connection again when safeguarding voltage transformer;
2, voltage transformer is an all insulation full-shield voltage transformer, and simultaneously through the voltage transformer head, High-Voltage Insulation cable, preceding plug-in cable joint are connected to three-position switch in the gas tank, and a whole set of voltage transformer cabinet is an all insulation voltage transformer cabinet;
3, because main bus bar and isolating switch all are integrated into gas tank inside, and volume is less, than similar voltage transformer cabinet long-pending at least 30%;
4, because the gas tank and the loading switch cabinet of the gas tank formula all insulation voltage transformer cabinet of this tri-station isolating switch, on-load switch fuse combination sideboard, the gas tank degree of depth of breaker cabinet is the same, and connected mode is the same with highly between the cupboard, and the versatility of unit is better.
