Abstract
The invention relates to a striker structure special for a vacuum contact-fuse-combined electric appliance, which is characterized in that a fuse connecting component and a support are connected together by a bolt, a shaft pin is fixed on the support through a through hole of a tongue sheet, one surface of the tongue sheet is connected with a pull rod through a stop block, and the stop block is fixed on the pull rod. The invention has the advantages that: a problem that a striker strikes a triggering device after a transitional F-C (Fuse-Contact) circuit fuse is broken is solved, the floor area of a striker mechanism is small, the strength is reliable, the device is simple, the assembly is easy and the combination of the fuse and a fuse cartridge is also easy. The striker structure disclosed by the invention has the characteristics of high degree of standardization, convenience for operation and maintenance and the like when applied to the contact-fuse-combined electric appliance; functions are improved, and the size precision is high; the application of products is flexible; and the assembled contact-fuse-combined electric appliance with a handcart-type structure can accord with mid-set switch cabinets of the majority of factories.
Description
Technical field
What the present invention relates to is the special-purpose striker structure of a kind of vacuum contactor-fuse combined electric apparatus.Various motor, transformer, capacitor are protected and controlled to the parts that can be assembled into solid-sealing vacuum contactor-fuse combined electric apparatus in electric power system, belong to the design and fabrication technology field of medium voltage switchgear equipment.
Background technology
In the high-voltage electrical apparatus technical field, vacuum contactor-fuse combined electric apparatus does not have special-purpose striker mechanism at present, all is to be formed by the part occasional combination, installs, dismantles inconvenience, the properties of product less stable, and the degree of product standardization is low.
Summary of the invention
What the present invention proposed is the special-purpose striker structure of a kind of vacuum contactor-fuse combined electric apparatus.Its purpose is intended to overcome the above-mentioned defective of existing in prior technology, and the characteristics at solid-sealing vacuum contactor-fuse combined electric apparatus are combined into special mechanism by part, has installation, convenient disassembly, standardization level height, characteristics such as reliability height.
Technical solution of the present invention: it is characterized in that comprising tongue piece, support, fuse connector, pivot pin, block, pull bar, wherein fuse connector, support link together with bolt, pivot pin is fixed on the support by the through hole on the tongue piece, the one side of tongue piece links to each other with pull bar by block, after tongue piece is stressed
Rotatablely move along the central axis that is fixed on the pivot pin on the support and to drive pull bar and move up and down.Fuse connector 3 adopts the self-constriction structure of contact terminal, has the spring of tying tight to guarantee that fuse contacts with the reliable of fuse connector above the fuse connector.
Advantage of the present invention: have the standardization level height, reliability height, characteristics such as handled easily and maintenance; The product structure novelty, complete function, dimensional accuracy height; The product applying flexible, the handcart-type structure contactor-fuse combined electric apparatus that is assembled into, the intermediate switchgear cabinet of the supporting most of producers of energy.
Description of drawings
Accompanying drawing 1 is the structural representation of the special-purpose striker mechanism of a kind of vacuum contactor-fuse combined electric apparatus.
Accompanying drawing 2 is partial views of Fig. 1.
Among the figure 1 is tongue piece, the 2nd, and support, the 3rd, fuse connector, the 4th, stiffener, the 5th, pivot pin, the 6th, pull bar, the 7th, block, the 8th, the molten tube of fuse bonnet, the 9th, sensitive switch.
Embodiment
The contrast accompanying drawing, its structure is to comprise tongue piece 1, support 2, fuse connector 3, stiffener 4, pivot pin 5, pull bar 6, block 7; Support 2, fuse connector 3, stiffener 4 are connected by bolt, and preformed hole on the support 2 and fuse canister center are coaxial; Pivot pin 5 is fixed on the support 2 by the through hole on the tongue piece 1, and the one side of tongue piece 1 links to each other with pull bar 6 by block 7, and block 7 is fixed on the pull bar 6.Can give tongue piece 1 release pressure by coaxial through-hole after the fuse blows, the central axis of the pivot pin 5 of tongue piece 1 on the support 2 is rotated, stir block 7, drive pull bar 6 and do rectilinear motion up and down.Trigger combined electrical apparatus sensitive switch 9, thereby divide deenergizing.Fuse connector 3 adopts the Mume flower contact structure, and the spring of tying tight above can guarantee that fuse reliably contacts with fuse connector 3, and stiffener 4 is used to strengthen the mechanical strength of fuse support.
