Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment; technical scheme in the utility model embodiment is clearly and completely described; obviously; described embodiment is only the utility model part embodiment; instead of whole embodiments; based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model provides a kind of technical scheme: a kind of manual adjustments automatically resets the hot condenser of dual metal type, comprise thermal element a1, heating element b4 and guide plate 8, described thermal element a1 is made up of resistance wire a2 and sheet metal a3, described sheet metal a3 and sheet metal b6 is inconsistent with convex conductor 7 respectively, described convex conductor 7 is arranged on guide plate 8, described guide plate 8 one end is provided with heat shield 9, described heat shield 9 is connected with push rod 12 one end by mobile 19, described push rod 12 other end is provided with spring 17, described spring 17 other end is connected on fixed body 18, described push rod 12 is inconsistent with transmission lever, pole 15 is provided with in the middle of described transmission lever 16, described pole 15 supports transmission lever 16 by setscrew nut 14, described setscrew nut 14 is arranged in reset button 13, described transmission lever 16 one end is provided with moving contact 11, described moving contact 11 is inconsistent with fixed contact 10, described thermal element a1, thermal element b4, convex conductor 7, guide plate 8, heat shield 9, push rod 12, transmission lever 16, moving contact 11 and fixed contact 10 are respectively electric conductor, because when conductor can be energized, condenser could work, described thermal element b4 is made up of resistance wire b5 and sheet metal b6, the sheet metal that described sheet metal a3 and sheet metal b6 two kinds of coefficients of expansion are different, described moving contact 11 is connected on control circuit path of winding with fixed contact 10.
First described thermal element a1 and thermal element b4, it is the major part of thermal relay, described sheet metal a3 and sheet metal b6 is bimetal leaf, and described resistance wire a2 and resistance wire b5 is resistance wire, it by bimetal leaf and around bimetal leaf outside resistance wire form.Bimetal leaf is formed by the sheet metal seam that two kinds of thermal coefficient of expansions are different.During use, resistance wire is directly serially connected on asynchronous quarter-phase circuit.Normally closed moving contact be connected on the contactor coil branch road of control circuit.When overload causes overcurrent; and after certain hour; the heat foot that described thermal element produces makes bimetal leaf bend; and promote guide plate 8 and to move right certain distance; described guide plate 8 promotes again the rotation of heat shield by mobile, and push rod, by spring 17 elastic force, makes moving contact 11 separate with fixed contact 10; thus line contactor power-off is discharged, power supply excision is played a protective role.After dump, thermal relay begins to cool down, and bimetallic restores to the original state after a while, so moving contact under the use of spring 17, automatically resets closed with fixed contact 10.As long as at this moment back-out to certain position by setscrew nut 14, make moving contact 11 exceed certain angle, in the case, even if bimetal leaf cooling, moving contact 11 can not automatically reset, and must adopt manually.
The utility model utilizes thrermostatic bimetal-plate heated bending to go promotion contact actuator and action for a kind of manual adjustments hot condenser of dual metal type that automatically resets, and adds promotion dynamics, makes condenser can complete conductivity between a device; Adopt setscrew nut, even if bimetal leaf cooling, moving contact can not automatically reset, manual adjustments must be adopted, after location, dump, condenser begins to cool down, bimetallic restores to the original state after a while, so moving contact is under the use of spring, automatically reset closed, reasonable in design with fixed contact, structure is simple, and Costco Wholesale is low.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
