Abstract
The utility model discloses a closed vacuum communicating contactor, a rectifying device, an auxiliary contact and a vacuum interrupter are encapsulated in a shell, the contactor is safe and good in using performance, long in using life, and also avoids the damage of the vacuum interrupter caused by accidental collision or the bad phenomenon of product contacting caused by that impurities enter the moving end of the vacuum interrupter. The contact terminal block of the auxiliary contact is connected with a wire holder by lead wires, which is convenient to connect wire for user, furthermore prolongs the using life of the product. The encapsulation structure can also reduce the volume of the whole product, is convenient for the selection of the drawer type switchgear.
Description
Technical field
The utility model relates to a kind of electromagnetic type vacuum A.C. contactor, particularly a kind of closed vacuum A.C. contactor.
Background technology
Seen in the market vacuum A.C. contactor is product at the beginning of the eighties, as CKJ5 low-voltage vacuum A.C. contactor, it comprises base, pedestal, rocking arm, calutron, vacuum interrupter, rectifying device, auxiliary contact and junction block, vacuum interrupter is that dynamic and static main contact is encapsulated in ceramic internal fixation, and the state that is evacuated, electric arc is extinguished fast.The vacuum A.C. contactor of this structure, conductive pieces exposed on the product is too many, vacuum tube, capacitor, rectifier diode and auxiliary contact etc. as rectifying device are installed in product surface, damaged in collision very easily, extraneous greasy dirt, dust and other impurities is also as easy as rolling off a log to pollute or corrodes vacuum tube, rectifier diode, electric capacity etc., influence its useful life, and overall dimension is bigger.
Summary of the invention
The problem that to be solved in the utility model is existing vacuum A.C. contactor weak point in useful life, volume is bigger provides a kind of closed vacuum contactor product.The technical scheme that addresses the above problem employing is: closed vacuum A.C. contactor comprises base, pedestal, rocking arm, calutron, vacuum interrupter, rectifying device and auxiliary contact, described rectifying device, auxiliary contact and vacuum interrupter encapsulate in the enclosure, and the contact of auxiliary contact is connected on the junction block.
Described rectifying device and auxiliary contact are encapsulated in the base by bonnet.
Described vacuum interrupter is encapsulated in the pedestal by top cover.
Described vacuum interrupter adopts the small size vacuum pipe.
Closed vacuum A.C. contactor of the present utility model, rectifying device, auxiliary contact and vacuum interrupter encapsulation are in the enclosure, safety and serviceability are good, long service life, and avoided accident collision to cause vacuum interrupter damage or foreign material to enter the vacuum interrupter moved end and caused product loose contact phenomenon; In addition, the contact binding post of auxiliary contact is connected on the junction block by lead-in wire, makes things convenient for terminal block, further prolongs the useful life of product.Its another advantage is the volume that this encapsulating structure can reduce entire product, is convenient to drawer-type switch cabinet and selects for use, and especially when described vacuum interrupter adopted the small size vacuum pipe, these characteristics were more obvious.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the closed AC vacuum contactor of the utility model.
Fig. 2 is the outline drawing of the closed AC vacuum contactor of the utility model.
Fig. 3 is the structure chart of a kind of AC vacuum contactor common in the prior art.
Fig. 4～Fig. 6 is respectively the structural representation of top cover, junction block and bonnet.
Embodiment
Shown in the accompanying drawing: 1--base, 2--coil, 3--yoke, 4--armature, 6--rocking arm, 7--reaction spring, 8--auxiliary contact, 9--bonnet, 10--adjust screw, 11--pedestal, 12--joint cover, 13--flexible connection, 14--vacuum interrupter, 15--top cover, 16--junction block
Closed vacuum A.C. contactor comprises base 1, pedestal 11, rocking arm 6, calutron, vacuum interrupter, rectifying device and auxiliary contact, product adopts three-dimensional standard to arrange, can make product with compact structure, cooperate said structure, described vacuum interrupter adopts the small size vacuum pipe, and be encapsulated in the pedestal 11 by top cover 15, avoided accident collision to cause vacuum interrupter to damage or foreign material enter the vacuum interrupter moved end and cause product loose contact phenomenon.Described rectifying device and auxiliary contact 8 are encapsulated in the base 1 by bonnet 9, and the contact binding post of auxiliary contact 8 is connected on the junction block 16 by lead-in wire, can make things convenient for terminal block, prolong the useful life of product.
By having increased contact pressure, reduce contact resistance, increase clearance between open contacts, improve make-break capacity, reduce the heating of contact in closed base, make the work of contact part more reliable.
