Technical field
The utility model relates to a kind of power equipment fuse, is specifically related to a kind of outdoor high-voltage alternating current fuse switch.
Background technology
Outdoor high-voltage alternating current fuse switch is the most frequently used a kind of protective switch of the short circuit of 10kV distribution line branch line and distribution transformer; it has economy, adapts to the features such as outdoor environment is strong, is widely used in 10kV distribution line and distribution transformer primary side as protection with carry out equipment throwing, cut the use of operation.It is arranged on 10kV distribution line branch line, can reduce power failure range, because it has an obvious cut-off point, has possessed the function of isolating switch, creates a safety work environment to maintenance section circuit and equipment, adds the sense of security of maintainer.But between current outdoor high-voltage alternating current fuse switch insulator and cross-arm when rainy as easy as rolling off a log generation flashover, cause insulating surface to damage, affect useful life, and sleet can affect the use of fuse.And when the arc-extinguishing tube of outdoor high-voltage alternating current fuse switch needs to change, because structure influence causes replacing very inconvenient.
Utility model content
Technical problem to be solved in the utility model is to provide one effectively can prevent insulator generation flashover, and is convenient for changing the outdoor high-voltage alternating current fuse switch of arc-extinguishing tube.
The technical scheme that the utility model adopts is: a kind of outdoor high-voltage alternating current fuse switch, and it comprises: insulator, the arc-extinguishing tube be connected with insulator upper end and one end are hinged with arc-extinguishing tube and the claw hook that is fixedly connected with insulator lower end of the other end; Described insulator upper end is also provided with clamping sheet, position-limited rack and is arranged on described insulator and can covers described clamping sheet and position-limited rack and cross section is U-shaped de-icer boot; Described clamping sheet one end and insulator are hinged, and the other end is connected with insulator by Compress Spring.
Described arc-extinguishing tube upper end is also provided with copper screw cap, described copper screw cap and the clamping of described clamping sheet; Described arc-extinguishing tube lower end is provided with gudgeon, and described gudgeon matches with the position guiding groove be arranged on claw hook; Also pressure spring plate is provided with between described arc-extinguishing tube and claw hook.
Being provided with cross-arm with arc-extinguishing tube opposite side on described insulator, described cross-arm is provided with two or more full skirt.
Described de-icer boot is provided with upper mounted plate, described claw hook is provided with bottom plate, described bottom plate is provided with the ground loop for ground connection electrical verification.
Good effect of the present utility model is on cross-arm, be provided with two and above full skirt, prevents insulator and cross-arm generation flashover, increases creepage distance, enhances the tautness of fastening rubber simultaneously, prevents cracking.Compress Spring is provided with between copper screw cap and de-icer boot, adopt enclosed construction, rainwater is avoided to enter into fusion tube inside, avoid the short circuit that free gas forms upper layer circuit to threaten, and avoid the arc-extinguishing medium to fusion tube inside to rainwater and humid area to cause the contraction distortion after making moist to fuse not falling obtaining the infringement that causes of phenomenon by it.Claw hook adopts and leads position design, when replacing, installation fusion tube, moment just can put insertion claw hook into fusion tube, removes and installs all fast very convenient, effectively enhances operating efficiency and accuracy.Be provided with ground connection electroscopic device simultaneously, electrical verification and ground connection can be carried out on this device, for the inspection and maintenance of insulated circuit provides a great convenience.
