Abstract
The utility model relates to a handcart with a fuse. The handcart comprises a handcart body, isolating plugs, a worm gear and a worm rod pushing mechanism, the isolating plugs are mounted on the handcart body, and the worm gear and the worm rod pushing mechanism are arranged at the bottom of the handcart body and in transmission connection. Compared with the prior art, the handcart with the fuse has the advantages of high insulativity, capability of replacing high-voltage fuses, convenience for inspection and maintenance.
Description
Technical field
The utility model relates to a kind of switching device for power distribution, especially relates to a kind of handcart with fuse.
Background technology
In the switch cubicle with fuse of routine, usually fuse is fixedly mounted in the cell that is separated out on the switch cubicle.Yet, because fuse is consumable accessory, again because fuse is fixed installation, therefore, cell and the live part at fuse place must be isolated fully when will be to change of fuse, even also can be with the whole system dump, thereby unnecessary power failure caused.In a single day especially, in case in the overall process of changing fuse, standard is lost in operation, namely misoperation occurs, can lead to the accident that jeopardizes personal safety so, this is not rarely had report at media yet.In addition because fuse is positioned at inside switch cabinet, the maintenance personal to the operation of changing fuse because very bothered by spatial limitation.
Summary of the invention
The purpose of this utility model is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of insulating properties is high, charged for replacement high voltage fuse, maintenance and inspection are not easily with the handcart of fuse.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of handcart with fuse, comprise handcart body, stab contact, worm gear and worm screw propulsive mechanism, described stab contact is installed on the handcart body, and described worm gear and worm screw propulsive mechanism are arranged on handcart body bottom, and described worm gear and worm screw propulsive mechanism are in transmission connection.
Be provided with high voltage fuse in the described stab contact.
The blowout current of described high voltage fuse is 1A.
Described stab contact is provided with 4-8.
Be connected with Special grounding wire on the described handcart.
The height of described handcart is 520mm～560mm.
Compared with prior art, the utlity model has following advantage:
1) the utility model is installed in high voltage fuse in the stab contact of handcart, can realize not charged for replacement high voltage fuse, and maintenance and inspection are convenient;
2) the utility model adopts Special grounding wire, and insulating properties is high.
Description of drawings
Fig. 1 is part-structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, a kind of handcart with fuse, comprise handcart body 1, stab contact 2, worm gear and worm screw propulsive mechanism, described stab contact 2 is installed on the handcart body 1, described worm gear and worm screw propulsive mechanism are arranged on handcart body 1 bottom, and described worm gear and worm screw propulsive mechanism are in transmission connection.Be provided with high voltage fuse in the described stab contact.The blowout current of described high voltage fuse is 1A, and the model of the high voltage fuse that present embodiment adopts is XRNP.Be connected with Special grounding wire on the described handcart.
Described stab contact can arrange as required, and stab contact is provided with 4 in the present embodiment.Described handcart is done the time spent and is inserted in the fuse chamber of switch cubicle, and its height should be complementary with switch cubicle, and in the present embodiment, the height of handcart is 520mm.
With reference to shown in Figure 1, a kind of handcart with fuse comprises handcart body 1, stab contact 2, worm gear and worm screw propulsive mechanism, and stab contact is provided with 8 in the present embodiment, and the height of handcart is 560mm.All the other are with embodiment 1.
