Description
Technical field
The utility model relates to a kind of power system device, particularly relates to a kind of vacuum load switch.
Background technology
Present fuse combined electric apparatus vacuum load switch divides three parts usually, comprises isolating switch part, vacuum interrupter part and fuse and earthed switch part.As a kind of indoor AC fuse combined electrical apparatus vacuum load switch, be applicable to ring network power supply or terminal powered switch element in the distribution systems such as industrial and mineral, enterprise, residential quarters, school with high and low breaking capacity.
But traditional fuse combined electric apparatus vacuum load switch its close/that brake separating mechanism and major loop leading-out terminal connect copper bar is too complicated, causes volume still bigger, the user designs power distribution cabinet and takes up room greatly sometimes, causes complete set of equipments cost excess waste.Traditional its insulated leg of fuse combined electric apparatus vacuum load switch also is only to have installed isolating switch and vacuum switch concentratedly, in the whole main conductive circuit, moistureproof, dustproof, insulation property, cut down the consumption of energy and aspects such as electric power that Short Circuit withstand causes all not good enough.Its switching-on mechanism particularly is not enough in the close a floodgate surge force intensity of anti-dynamic and thermal stability electric current in service of switch; Separating brake dropout parts connecting link is too various, and the fuse combined electric apparatus switch divides the time long admittedly, causes factors such as switch interrupting performance instability, causes more apparatus failure, increases the electric equipment maintenance cost.
Summary of the invention
For addressing the above problem, the utility model provides a kind of structure the compact more combined vacuum load switch of fuse electrical equipment.
The utility model solves the technical scheme that its technical problem adopted:
The combined vacuum load switch of a kind of fuse electrical equipment; Comprise switch framework, walking abreast on the switch framework is provided with three insulating supports, and the top of insulating support is provided with isolation knife; The middle part of insulating support is provided with the vacuum interrupter that links to each other with isolation knife; The outside of vacuum interrupter is provided with and is used to hold and at the support cavity of its outside sealed vacuum arc control device, the bottom of insulating support is equipped with down the conducting copper mold insert, is provided with the ground connection connecting lever portion that is used to be coupled to each other between the following conducting copper mold insert on three insulating supports and adorns; Linking to each other with vacuum interrupter also is provided with fuse clips portion dress, is provided with down fuse clips portion mutually with following conducting copper mold insert and adorns.
Further as the improvement of the utility model technical scheme, last fuse clips portion dress is installed on the bottom outside of support cavity, and the bottom of the inherent vacuum interrupter of support cavity also is provided with being flexible coupling of connecting with last fuse clips portion dress.
Further as the improvement of the utility model technical scheme, following conducting copper mold insert does not directly link to each other with being flexible coupling.
The beneficial effect of the utility model: fuse clips portion dress one was installed on parallel being arranged on the insulating support on the switch framework about the combined vacuum load switch of this fuse electrical equipment reached isolation knife, vacuum interrupter, conducting copper mold insert; Make the combined vacuum load switch structure of fuse electrical equipment compact more; When effectively saving its installing space; Make the combined vacuum load switch of fuse electrical equipment have higher reliability, and guarantee switch stable operation.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model embodiment overall structure sketch map;
Fig. 2 is the utility model embodiment insulating support centre section sketch map;
Fig. 3 is the utility model insulating support organigram.
Embodiment
With reference to Fig. 1～Fig. 3; The utility model is the combined vacuum load switch of a kind of fuse electrical equipment; Comprise switch framework 1, walking abreast on the switch framework 1 is provided with three insulating supports 2, and the top of insulating support 2 is provided with isolation knife 21; The middle part of insulating support 2 is provided with the vacuum interrupter 22 that links to each other with isolation knife 21; The outside of vacuum interrupter 22 is provided with and is used to hold and at the support cavity 23 of its outside sealed vacuum arc control device 22, and the bottom of insulating support 2 is equipped with down 24 of following conducting copper mold inserts on 24, three insulating supports 2 of conducting copper mold insert and is provided with the ground connection connecting lever portion that is used to be coupled to each other and adorns 3; Linking to each other with vacuum interrupter 22 also is provided with fuse clips portion and adorns 4, is provided with down fuse clips portion mutually with following conducting copper mold insert 24 and adorns 5.
The combined vacuum load switch of this fuse electrical equipment with isolation knife 21, vacuum interrupter 22, conducting copper mold insert and go up fuse clips portion adorn 4 and following fuse clips portion adorn 5 one and be installed on to walk abreast and be arranged on the insulating support 2 on the switch framework 1; Make the combined vacuum load switch structure of fuse electrical equipment compact more; When effectively saving its installing space; Make the combined vacuum load switch of fuse electrical equipment have higher reliability, and guarantee switch stable operation.
The combined vacuum load switch of fuse electrical equipment of this type of setting simultaneously has the advantage of aspects such as volume is little, light weight, useful life that also can the combined vacuum load switch of corresponding raising fuse electrical equipment.
As the utility model preferred embodiment, last fuse clips portion adorn 3 be installed on support cavity 23 bottom outside, the bottom of support cavity 23 inherent vacuum interrupters 22 also be provided with last fuse clips portion adorn 4 connect be flexible coupling 25.
As the utility model preferred embodiment, following conducting copper mold insert 24 25 does not directly link to each other with being flexible coupling.
As the combined vacuum load switch of fuse electrical equipment, the following conducting copper mold insert 24 of this vacuum load switch 25 does not directly link to each other with being flexible coupling of linking to each other with vacuum interrupter 22.
Fuse (not marking among the figure) is fixedly clamped down in the fuse clips of vacuum interrupter 22 with the leading-out terminal copper bar by insulating support 2 support and connection; On the fuse that the fusing folder portion of the combined insulating support matching and fixing of fuse electrical equipment loads onto crash panel is installed, crash panel is connected with switch separating brake tripping mechanism by a plastic tie that has a plurality of shirt rims.When switch in the charging operation state, when switch was met short circuit current, the fuse striker was knocking-on; Touch crash panel, under switch separating brake tripping mechanism connector action this moment, switching mechanism is influenced by external force; Force the switch opens vacuum interrupter, thereby reach the purpose of protection subordinate electric elements.
Certainly; The invention is not limited to above-mentioned execution mode; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
