Abstract
The utility model relates to a handcart provided with a fuse, belonging to the technical field of electric appliance switch cabinets. The handcart comprises a handcart body, and is characterized by also comprising a fuse assembly and an insulating cylinder with a containing cavity, wherein the fuse assembly is configured inside the insulating cylinder containing cavity, and the insulating cylinder is mounted on the handcart body. The handcart provided with a fuse has the advantages that: the fuse assembly is configured on the insulating cylinder, and the insulating cylinder is mounted on the handcart body, such that when a damaged fuse tube is replaced, all that is needed to remove the handcart body out of the switch cabinet, thereby ensuring safety, providing convenience for replacement and shortening replacement time.
Description
Technical field
The utility model belongs to the electrical switchgear technical field, is specifically related to a kind of handcart that disposes fuse
Background technology
such as industry the reason of knowledge, high pressure (like 40.5KV) withdraw-type AC metal closed switch cabinet, switch cabinet body are made up of breaker chamber, bus-bar room, four parts in cable vault and control room usually.In the switch cubicle that has fuse of routine, usually fuse is fixedly mounted in the cell that is separated out on the switch cubicle.Yet, because fuse is a consumable accessory, again because fuse is fixed installation; Therefore; Must the cell and the live part at fuse place be isolated fully when will be change of fuse, even also can be with the whole system dump, thereby unnecessary power failure caused.In a single day especially,, promptly misoperation occurs, can lead to the accident that jeopardizes personal safety so, this is not rarely had report at medium yet in case in the overall process of changing fuse, standard is lost in operation.In addition, because fuse is positioned at switch cubicle inside, the maintenance personal very bothers because of receiving spatial constraints the operation of changing fuse.
Deficiency in view of above-mentioned prior art is necessary to improve, and the technical scheme that will introduce below produces under this background
Summary of the invention
The task of
the utility model is to provide a kind of and helps avoid misoperation and use and guarantee safety and be of value to the maintenance personal and easily the change of fuse that damages used the handcart that disposes fuse that shortens the major loop power-off time.
The task of
the utility model is accomplished like this; A kind of handcart that disposes fuse; Comprise the handcart body; The insulating cylinder that it is characterized in that also comprising fuse assembly and have cavity volume, fuse assembly is disposed in the insulating cylinder cavity volume, and insulating cylinder is installed on the described handcart body.
described fuse assembly of the utility model comprises fusion tube, upper and lower contiguous block, upper and lower conducting block, goes up contact arm and following contact arm; Last contiguous block is fixed on the upper end of fusion tube; Lower connecting block is fixed on the lower end of fusion tube, and an end of last conducting block is connected with last contiguous block, and upward the other end of conducting block is connected with last contact arm; One end of following conducting block is connected with an end of lower connecting block; And the other end of conducting block is connected with following contact arm down, and wherein: fusion tube is positioned at described cavity volume, and upper and lower contact arm walks abreast with level each other and fixes with said insulating cylinder.
The technical scheme that
the utility model provides is disposed on the insulating cylinder owing to fuse assembly; And insulating cylinder is installed on the handcart body; Therefore in the time will changing to the fusion tube that causes damage; Only need the handcart body is shifted out switch cubicle, both can guarantee safety, conveniently replaced again and use and shorten the replacing time.
Description of drawings
Fig. 1 is the example structure figure of the utility model.
Embodiment
Fig. 1 is asked for an interview in
, has provided handcart body 1, fuse assembly 2 and insulating cylinder 3, and fuse assembly 2 is provided in the insulating cylinder 3, and insulating cylinder 3 is installed on the handcart body 1.
aforesaid fuse assembly 2 comprises fusion tube 21, upper and lower contiguous block 22,23, upper and lower conducting block 24,25, goes up contact arm 26 and following contact arm 27; With present location status shown in Figure 1 is example; Whole fusion tube 21 is positioned at the cavity volume 31 of insulating cylinder 3, and last contiguous block 22 is fixed on the upper end of fusion tube 21, and lower connecting block 23 is fixed on the lower end of fusion tube 21; An end that is positioned at the last conducting block 24 of cavity volume 31 is electrically connected with last contiguous block 22; And the other end of going up conducting block 24 is electrically connected with last contact arm 26, and an end that is positioned at the following conducting block 25 of cavity volume 31 equally is electrically connected with lower connecting block 25, and the other end of conducting block 25 is electrically connected with following contact arm 27 down.
by shown in the figure, upper and lower contact arm 26,27 keeps parallel up and down with level each other, upper and lower contact arm 26,27 be used for switch cubicle in fixed contact inserting mutually.When handcart body 1 pushed in the switch cubicle, then upper and lower contact arm 26,27 was inserted into aforesaid fixed contact, otherwise when handcart body 1 shifted out switch cubicle, then upper and lower contact arm 26,27 separated with fixed contact, breaks off major loop.
When needs are changed fusion tube 21; So as long as handcart body 1 shown in Figure 1 is outwards shifted out in switch cubicle; Thereby maintenance personal's working space is unrestricted and can fast change, and makes the time of changing fuse be able to ultimate attainment shortening, has practiced thrift the time of major loop outage; Owing to after handcart body 1 shifts out switch cubicle, break off, therefore be able to ensure maintenance personal's safety with main circuit power
