Abstract
The utility model provides a protective fuse type isolating switch, which is composed of a switch seat body, a door cover and fusion tubes. The inner cavity of the seat body is connected with the seat body between out phase touch seats, which is provided with an insulating longitudinal partition plate. The fuse is hung at the inner side of the door cover, which is connected with a cover body between the fusion tubes, which is provided with an insulating isolating plate. The door cover and the seat body are closed through movable fit connection. Correspondingly, the fusion tubes and the touch seats are closed through movable fit connection, and the longitudinal partition plate and the isolating plate are closed through movable fit connection. The utility model has the advantages of novel structure, reasonable design, safe protective function and convenient use, and is suitable for fitting connection in the electric system of 1.2KV and less than 1.2KV. The utility model is a novel fuse type isolating switch.
Description
The utility model relates to a kind of protection switch in the electroporation field, especially a kind of fuse disconnecting switch that is applicable in 1.2KV and the following electrical system.
In known technology, the switch with knifeshaped fuse that existing fuse disconnecting switch mainly is made up of switch pedestal, switch handle of a knife and fuse tube, it is packing less open type fusing isolating switch, especially naked shields and the switch cover cap between the fuse tube, make that occurring hindering electric current for some reason when the generation misoperation causes arc short-circuit or operation causes abnormal conditions such as fuse tube explosion, more easily injure operating personnel, have unsafe factor, also bring inconvenience to use.
The purpose of the utility model provide a kind of novel structure, can security protection, new type fuse formula isolating switch easy to use.
For achieving the above object.Technical solution adopted in the utility model is: adopt the isolating switch pedestal by insulation, door closure and fuse tube are formed, be shaped on the insulation midfeather between the out of phase touch base in load wiring touch base and the present intracoelomic cavity in the switch pedestal, door closure is connected in the isolating switch pedestal by door-hinge, be shaped on the insulation division board on the lateral body in the door closure inboard company of extension fuse tube and the door closure between fuse tube, fuse tube cooperated the company of inserting when pedestal was closed in the make and break of door closure lid with touch base, the division board of door closure touches superimposed the connection with the midfeather side in the pedestal, consists of the protection type fuse disconnecting switch of closing seam.During use, this fuse disconnecting switch is connected in the power circuit, operating personnel push and plug fuse tube into touch base by the push-and-pull door closure or pull out touch base, just can realize the disconnection or the connection of circuit, can also take off or change fuse tube easily from door closure.
Because fuse disconnecting switch of the present utility model has adopted the closing seam formula structure that is connected to form by pedestal, door closure and fuse tube, especially on pedestal and door closure, be shaped on the dividing plate that is superimposed with each other and is connected, can draw back door closure make fuse tube pull out touch base cut off circuit before and closed door closure make fuse tube insert touch base connect circuit before the division board maintenance commissure closed state of midfeather and door closure of pedestal, formation is to insulation shielding reliably between the electricity of isopic zone not body, and door closure also forms safety every cover between operating personnel and electrified body.Like this, both made that in service or when operation occurs hindering abnormal conditions such as electric current causes that fuse tube breaks for some reason at circuit, and also can significantly reduce the accident development, and avoided operating personnel to come to harm, and can prevent from again to cause arc short-circuit because of misoperation.Therefore, the utility model than existing switch with knifeshaped fuse novel structure, reasonable in design, have function of safety protection, easy to use, be applicable to join to be connected in 1.2KV and the following electrical system, be a kind of novel fuse disconnecting switch.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the cutaway view of the utility model embodiment concrete structure.
Fig. 2 is the uncap left TV structure figure of state of Fig. 1 embodiment.
Reference numeral is: 1 isolating switch pedestal, 2 midfeathers, 3 division boards, 4 fuse tubes, 5 touch bases, 6 door closures.
As accompanying drawing 1, embodiment illustrated in fig. 2, the utility model comprises: isolating switch pedestal (1), door closure (6) and fuse tube (4), be fitted with wiring touch base (5) in pedestal (1) inner chamber and insulation midfeather (2) arranged in the pedestal first line of a couplet system between the homophase touch base not, fuse tube (4) is hung by hanging handle and is connected in door closure (6) inboard, door closure (6) connects isolating switch pedestal (1) by door-hinge, and is shaped on insulation division board (3) between the not homophase fuse tube of load on the inboard lid of door closure (6).Pedestal (1) is closed in door closure (6) connection cover make and break movingly, correspondingly the fuse tube (4) of the company of extension inserts the touch base (5) that connects on the pedestal (1) movingly in the door closure (6), midfeather (2) on division board (3) on the door closure (6) and the pedestal (1) is staggered superimposed the connection movingly, and when door closure and pedestal closure, division board and midfeather are superimposed prior to touching with regard to the realization friendship before the company of touching of fuse tube and touch base, are not constituting reliable insulation shielding between isopic zone electricity body when guaranteeing to operate.
Isolating switch pedestal of the present utility model (1) and door closure (6) are to be made by insulating material.
Claims (2)
1, a kind of protection type fuse disconnecting switch, it comprises the isolating switch pedestal, fuse tube, it is characterized in that also comprising door closure (6), pedestal first line of a couplet system in isolating switch pedestal (1) inner chamber between the not homophase touch base (5) of load has insulation midfeather (2), fuse tube (4) is hung and is connected in door closure (6) inboard, door closure (6) connects switch pedestal (1) by door-hinge, and on the lid between the not homophase fuse tube of the inboard load of door closure (6), be shaped on the insulation division board (3), door closure (6) and pedestal (1) are connected closed movingly, correspondingly the company of touching movingly of the touch base (5) on the fuse on the door closure (4) and the pedestal, division board on the door closure (3) and the staggered movingly superimposed insulation shielding that connects and composes of the midfeather (2) of pedestal.
2, fuse disconnecting switch according to claim 1 is characterized in that isolating switch pedestal and door closure (6) are to be made by insulating material.
