Technical field
The utility model relates to a kind of dry-type capacitor, especially relates to the explosion-proof dry-type capacitor of a kind of no thread terminal machinery.
Background technology
Present mechanical explosion-proof electric capacity has generally adopted oily formula structure, is about to capacitor body and is installed in the shell, adds a cover sealing after filling with oil, draws terminal and is generally electric wire or 0.8 * 6.3 inserted sheet (being commonly called as 250 terminals).The ubiquitous problem of oil formula structure capacitive device is easy leakage of oil, contaminated environment; Its two be oil to the influence of capacitor film, normal under the general temperature, when temperature was higher, swelling can appear in capacitor film, influences capacitor life-span.Unless use silicone oil, cost are very high.The electric wire terminal line length of oil formula structure capacitive device is fixed, and therefore can not satisfy the needs of different product; 250 terminals need be joined 250 plugs when wiring, and electrode exposes, and need add insulation, otherwise dangerous.
Summary of the invention
The purpose of this utility model is exactly that a kind of have double insulation protection, the explosion-proof dry-type capacitor of no thread terminal machinery safe in utilization are provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
The explosion-proof dry-type capacitor of a kind of no thread terminal machinery, it is characterized in that, this capacitor comprises terminal assemblies, assembly of lid, burst disk, Copper Foil, insulative, core assembly, discharge resistance, end cover, shell and insulating paper, described Copper Foil is with insulated tube outward, one end of Copper Foil is welded on the fuse, the other end is welded on the assembly of lid by the burst disk point, put into insulating paper in the enclosure, discharge resistance is welded in two end faces of fuse, then fuse is placed in the shell, bottom cover upper base cover, in shell, pour into the dry type epoxy, the end face of sealing fuse, and fix end cover, lid assembly and sealing are pressed into terminal assemblies at last on assembly of lid.
Described terminal assemblies comprises no thread terminal and two plug in reed.
Described two plug in reed places no thread terminal.
Described assembly of lid comprises inserted sheet, single bowl, lid, sealing ring, insulation board, rivet.
Be with insulation board and sealing ring on the described rivet successively, connect lid and single bowl, inserted sheet is set in single bowl by rivet.
Described assembly of lid utilizes the sealed cans cover on shell.
The bottom of the explosion-proof dry-type capacitor of described no thread terminal machinery is with end cover.
Compared with prior art, the utility model has adopted dry construction, has avoided the leakage of oil drawback of oily formula electric capacity, the film thermosol that oily formula capacitor produces can not occur and expand under the condition of high temperature, has improved properties of product; By design, solved the explosion-proof security of the explosion-proof electric capacity of dry type preferably to burst disk; Increase end cover to the capacitor core centralized positioning, guaranteed the dielectric strength of shell; The no thread terminal assembly of design is connected with the inserted sheet of assembly of lid, only need insert electric wire during use, and is easy to use, safe and reliable.
