Embodiment
Please Shenfu Fig. 2, a kind of altitude range is the middle-placed switch cabinet fuse handcart of 639mm-643mm, comprises handcart body 110, fuse 120 and is separately positioned on upper contact arm 140, lower contact arm 130 on handcart body 110.Connect the front contact arm 132 that is provided with the insulation contact arm 131 of tubular on lower contact arm 130 and is connected with Mume flower contact between upper contact arm 140 and lower contact arm 130 by conducting element 150.
Wherein, an end of insulation contact arm 131 contacts with conducting element 150, and the other end contacts with front contact arm 132.Have the host cavity 1311 that can accommodate fuse 120 in insulation contact arm 131, this host cavity 1311 can be with in before part, contact arm 132 be housed in.Offer screw on the internal face of insulation contact arm 131, offer screw thread at front contact arm 132 with the corresponding junction of insulation contact arm 131, be connected by screw thread between front contact arm 132 and the contact arm 131 that insulate.In other embodiments, before the part, contact arm 132 also can be connected in host cavity 1311.
The fuse 120 that is housed in insulation contact arm 131 host cavities 1311 is connected between conducting element 150 and front contact arm 132, and conducting element 150 is by this fuse 120 and front contact arm 132 conductings.Reliability in order to ensure fuse 120 connects also is provided with the flexible member 160 with conductive capability in host cavity 1311, fuse 120 is pressed between conducting element 150 and front contact arm 132 by this flexible member 160.
Consider that fuse 120 can give out to the external world part heat in the course of the work, in preferred version, insulation contact arm 131 side wall surfaces radially and week upwards offer several relative ventilation holes, thereby guarantee middle-placed switch cabinet use fuse handcart when work, fuse 120 remains at steady-working state.
Middle-placed switch cabinet is with also comprising an end and upper contact arm 140 or the lightning arrester 170 that descends contact arm 130 to be conducted on fuse handcart 100, the other end of lightning arrester 170 is connected with the earth.The importing of lightning arrester 170 can make middle-placed switch cabinet exempt from the harm of instantaneous voltage and the attack of lightning surge with fuse handcart 100.When the overvoltage of importing fuse handcart 100 along circuit into or lightning surge surpassed the level of protection of lightning arrester 170, at first lightning arrester 170 discharged, and with the flow through introducing the earth of good conductor safety of overvoltage.Utilize earthing device to make the lightning voltage amplitude limitation below horizontal at protected equipment lightning impulse, the electric equipment that is arranged on fuse handcart 100 is protected.
In addition, middle-placed switch cabinet also comprises for the disjunctor insulator 111 with upper contact arm 140 and lower contact arm 130 and 110 insulation of handcart body with fuse handcart 100, upper contact arm 140 or lower contact arm 130 are fixed on corresponding with it disjunctor insulator 111 by double-screw bolt 180, and conducting element 150 be pressed in contact arm 130,140 and double-screw bolt 180 between.
The middle-placed switch cabinet of the present embodiment with fuse handcart 100 in the course of the work, the electric current that imports by upper contact arm 140 flow through respectively conducting element 150, flexible member 160, fuse 120 finally flow in the Mume flower contact of lower contact arm 130.When the electric current that flows into this path is excessive, fuse 120 fusing, thus play protection fuse handcart 100 and be arranged on the effect of the circuit in electric equipment on fuse handcart 100.
Adopt the middle-placed switch cabinet of above-mentioned design with fuse handcart 100, fuse 120 to be built in handcart contact arm, overcome conventional method fuse 120 is fixedly mounted between upper contact arm 140 and lower contact arm 130, the shortcoming that easily causes fuse 120 to damage.When can ensureing fuse 120 functions, with protecting of its safety.In this simultaneously, this design can also be saved the use amount of the electric conducting material of handcart contact arm, thereby reduces its production cost.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
