Abstract
The present utility model discloses a load type vacuum load switch which comprises a switch framework, three insulation supports are arranged in parallel on the switch framework, an isolation knife is arranged on the upper part of each insulation support, a vacuum arc-extinguishing chamber connected with the isolation knife is arranged on the middle part of each insulation support, a support cavity which is used for accommodating and sealing the vacuum arc-extinguishing chamber from the outside is arranged outside the vacuum arc-extinguishing chamber, a lower conductive copper bar mold insert connected with the vacuum arc-extinguishing chamber is arranged outside the support cavity, and grounding crankarm parts for connecting with each other are arranged between the lower conductive copper bar mold insert of the three insulation supports. In the load type vacuum load switch, the isolation knives, the vacuum arc-extinguishing chambers, and the lower conductive copper bar mold inserts are integrally arranged in parallel on the insulation supports of the switch framework, the structure of the load type vacuum load switch is more compact, the installation space is effectively saved, the reliability of the load type vacuum load switch is higher, and the stable operation of the switch can be ensured. The load type vacuum load switch can be used in the electrical equipment field.
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 load type 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 load type 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 load type 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 load type 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, 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.
Summary of the invention
For addressing the above problem, the utility model provides a kind of structure compact more load type vacuum load switch.
The utility model solves the technical scheme that its technical problem adopted:
A kind of load type vacuum load switch; Comprise switch framework; Walk abreast on the switch framework and be provided with three insulating supports; The top of insulating support is provided with isolation knife, and the middle part of insulating support is provided with the vacuum interrupter that links to each other with isolation knife, and 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 outside of support cavity is provided with the following conducting copper mold insert that links to each other with vacuum interrupter, is provided with the ground connection connecting lever portion dress that is used to be coupled to each other between the following conducting copper mold insert on three insulating supports.
Further as the improvement of the utility model technical scheme; Be provided with stationary contact head dress on the top of insulating support; The top, the outside of support cavity is provided with the copper mold insert; The stationary contact head is loaded onto and is provided with the buffered silica gel of fitting with stationary contact head dress, and around the last copper mold insert and top is respectively equipped with the silicon rubber cup that is used to protect the silica gel plug of copper mold insert and is covered on silica gel plug top.
Further as the improvement of the utility model technical scheme, cooperate to be provided with the support cavity to be used for sealed vacuum arc control device and transparent visual protective cover.
The beneficial effect of the utility model: this load type vacuum load switch is installed on parallel being arranged on the insulating support on the switch framework with isolation knife, vacuum interrupter and conducting copper mold insert one; Make load type vacuum load switch structure compact more; When effectively saving its installing space; Make load type vacuum load switch 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 a kind of load type vacuum load switch; 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 outside of support cavity 23 is provided with 24 of following conducting copper mold inserts on 24, three insulating supports 2 of following conducting copper mold insert that link to each other with vacuum interrupter 22 and is provided with the ground connection connecting lever portion that is used to be coupled to each other and adorns 3.
This load type vacuum load switch is installed on parallel being arranged on the insulating support 2 on the switch framework 1 with isolation knife 21, vacuum interrupter 22 and conducting copper mold insert one; Make load type vacuum load switch structure compact more; When effectively saving its installing space; Make load type vacuum load switch 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; Be provided with the stationary contact head on the top of insulating support 2 and adorn 4; The top, the outside of support cavity 23 is provided with copper mold insert 5; The stationary contact head is adorned 4 and is provided with the buffered silica gel 41 of adorning 4 applyings with the stationary contact head, and around the last copper mold insert 5 and top is respectively equipped with the silicon rubber cup 61 that is used to protect the silica gel plug 6 of copper mold insert 5 and is covered on silica gel plug 6 tops.
