Description
Technical field
The utility model is related to isolated switchgear technical field, specially a kind of electronic load-break switch of Fuse Type.
Background technology
At present, the fuse in the 10kV line systems in reality and on distribution transformer is unable to correct operation, and it is former
Therefore one is, electrician's quality is poor, lacks a sense of responsibility, throughout the year without the maintenance and maintenance of fuse switch；The two of reason are,
The product quality of fuse switch is inferior, it is impossible to flexible drawing, closing operation.Two reasons reduce the work(of fuse switch
Energy.Often occur lacking fusion tube, lack melt or replacing the situation of melt with copper wire, aluminium wire even iron wire hooking in reality.So that
The trip-out rate of circuit and the fault rate of distribution transformer are high.On-load switch refers to cut-off and close rated load current
Switch, because on-load switch is easy to use, reasonable price has certain arc extinguishing ability, therefore can be used to cut-off and close negative
The overload current of charged current and small dry certain multiple；May also be used for cut-offfing and close allows the bigger sky of capacity than disconnecting switch
Transformer is carried, longer nonloaded line is also used for cut-offfing and closing the capacitor bank of Large Copacity sometimes；On-load switch melts with current limliting
Disconnected device tandem compound can be used instead of breaker.The overload electricity for cut-offfing and closing less than certain multiple is undertaken by on-load switch
Stream, and undertaken by limiting fuse and cut-off larger overload current and short circuit current flow.Existing fuse type load-break switch,
It is extremely wide using face, but there is following defect in existing product：Switch blade or contact on do not install anti-melting welding copper graphite or
Copper-tungsten arcing contact, when switching on-load separating brake, operator and main contact contact surface are easily burnt by arcing, and are opened
Without obvious cut-off point during the separating brake of pass；Switch without quick-action operating mechanism, division speed is slower, directly affect switch arc extinction performance and
Service life；What most of disconnecting switch used at present in addition is all manual quick closing valve, troublesome poeration, and dangerous, it is impossible to protected
Hinder the safety of operating personnel.
The content of the invention
The purpose of this utility model is to provide a kind of electronic load-break switch of Fuse Type, to solve above-mentioned background technology
The problem of middle proposition, had an advantageous effect in that：The utility model removes straight from by the separating brake and combined floodgate of electric controling switch
Connect and operated with handle, security is higher.
To achieve the above object, the utility model provides following technical scheme：A kind of electronic load-break switch of Fuse Type,
Including electrical header, arc-chutes, contact system, fuse link and base plate, plate, and electrical header are installed above the electrical header
Lower section is connected with base plate, and the arc-chutes are arranged on above base plate, and is provided with insulated terminal, the insulating end at the top of arc-chutes
Static contact is fixed with son, and static contact is connected with contact system, the contact system is fixed in the middle of base plate, and contact system
Including static contact, moving contact connecting rod, moving contact, fixed plate and side plate, the moving contact connecting rod is bolted to solid by first
In fixed board, and fixed plate is connected by the second bolt and the 3rd bolt with side plate respectively, the contact connecting rod bottom and base plate it
Between be provided with moving contact pedestal, the moving contact is fixed on below moving contact connecting rod, and fuse link is arranged between contact connecting rod,
The bottom base plate is connected with lower plugboard.
It is preferred that, the base plate both sides, which are provided with gland, and gland, is provided with connecting hole.
It is preferred that, the electrical header is connected by connecting rod with arc-chutes.
It is preferred that, it is provided with the first spring on first bolt.
It is preferred that, it is provided with second spring below the fixed plate.
Compared with prior art, the beneficial effects of the utility model are：With small volume, big capacity, dependable performance, operation
Simply, the advantage of compact overall structure, due to modularization install cause adjust dilatation flexibility it is high, can on-site consolidation, apply
Work is convenient.Fuse type load-break switch is directly articulated on busbar, saves wire.Maintenance personal can direct band at the scene
Load operation is switched, and changes fuse link.Current-limiting type fuse can avoid electric power up to caused by 80kA short circuit current flows from impacting, and make
Distribution line is from the destruction of short circuit current flow and overload electric current, and the design of electrical header in addition can make the equipment realize Electronic control
The separating brake and combined floodgate of switch, remove from and directly being operated with handle, security is higher.
