with fixed mount 9,The top outer wall of bimetal leaf 6 is provided with bracing frame 20,Bracing frame 20 is of an L-shaped structure,Bracing frame 20 one end is connected with bimetal leaf 6,The other end connects limited location plate 19,Limiting plate 19 is arranged on above bimetal leaf 6,Guide plate 8 it is provided with between fixed mount 9 and bimetal leaf 6,Fixed mount 9 forms chute 18 near the end face indent of guide plate 8,And chute 18 connects with the two ends of fixed mount 9,The bottom of guide plate 8 is arranged in chute 18,And guide plate 8 can move horizontally along fixed mount 9,The top indent of guide plate 8 forms several grooves,The bottom of bimetal leaf 6 is correspondingly arranged in a groove,Resistance wire 7 it is provided with between adjacent bimetal leaf,Resistance wire 7 one end connects with the center lower end of corresponding bimetal leaf 6 respectively,One end of guide plate 8 connects push rod 12,Push rod 12 has compensation bimetal leaf 13 away from one end connection of guide plate 8,Compensate and be provided with connecting plate 22 between bimetal leaf 13 and push rod 12,Connecting plate 22 is connected with compensation bimetal leaf 13 and push rod 12 simultaneously,Buffer spring 23 it is provided with between connecting plate 22 and fixed mount 9,Buffer spring 23 is connected with connecting plate 22 and fixed mount 9 simultaneously,Buffer spring 23 is arranged on below push rod 12,Compensate bimetal leaf 13 connection and have push rod 3,Push rod 3 one end connects connecting rod 17,Connecting rod 17 connects adjustment cam 2 and compression spring 1,And connecting rod 17 is arranged between adjustment cam 2 and compression spring 1,Adjustment runner 21 it is provided with in adjustment cam 2,And it is concentric with adjustment cam 2 to adjust runner 21,Push rod 3 has leaf spring 16 away from one end connection of connecting rod 17,Leaf spring 16 connects movable contact 11、Bow spring 5 and manual reset button 4,And bow spring 5 and movable contact 11 connect,Stationary contact 10 it is provided with between movable contact 11 and bimetal leaf 6,And stationary contact 10 is arranged on above guide plate 8,Compensate and between bimetal leaf 13 and movable contact 11, be provided with reset regulation screw 14,And the termination of the regulation screw 14 that resets is near compensating bimetal leaf 13,The regulation screw 14 that resets is arranged on the top of push rod 12;Described push rod 3 is of an L-shaped structure, and compensates bimetal leaf 13 and is connected with the bending point of L-type structure;Described push rod 3 is provided with rotating shaft 15 near one end of connecting rod 17, and rotating shaft 15 can rotate around rotating shaft 15 also cross push rod 3 and connecting rod 17, push rod 17.In the technical program, three pieces of bimetal leafs 6 of preferential employing, between adjacent bimetal leaf 6, resistance wire 7 is set, push rod 12 and stationary contact 10 are close to leftmost bimetal leaf 6, in order to ensure that bimetal leaf 6 entirety when temperature distortion will not move, specially it is provided with limiting plate 19 and bimetal leaf 6 is fixed by bracing frame 20, its position is fixed, ensure that stability when relay works, during use, being serially connected in respectively in the three-phase main circuit of computer by the three-phase thermal element of electrothermal relay, break contact is serially connected in the contactor coil loop of control circuit.When computer transships, the electric current flowing through resistance wire 7 exceedes the setting current of electrothermal relay, resistance wire 7 generates heat, bimetal leaf 6 bends to the right, guide plate 8 is promoted to move right in chute 18, push rod 12 is made to pull compensation bimetal leaf 13 to move, in this process, when push rod 12 pulls too fast, easily cause connecting plate 22 and the shock of fixed mount 9, in order to prevent this situation, between connecting plate 22 and fixed mount 9, it is provided with buffer spring 23 protect, push rod 3 is promoted 15 to rotate around the shaft by compensating bimetal leaf 13, thus promote contact system action, movable contact separates with dynamic circuit breaker stationary contact, make contactor coil power-off, contacts of contactor disconnects, power supply excision is shielded.After power supply excision, bimetal leaf 6 gradually cools down and sets back, and then movable contact is in the case of ineffective power, and the elasticity by bow spring 5 automatically resets.This electrothermal relay may be used without hand-reset, again puts into operation with equipment belt fault before preventing failture evacuation.Reset regulation screw 14 being outwards adjusted to certain position, makes the certain angle that rotates more than of movable contact bow spring lose least, even if the cooling of the most main bimetal leaf is restored, movable contact can not automatically reset, it is necessary to uses hand-reset.Pressing SR, movable contact bow spring returns to have resilient angle, promotes movable contact to recover Guan Bi with stationary contact.When variation of ambient temperature, bimetal leaf 6 can occur null offset, i.e. thermal element not to be deformed by main bimetal leaf during electric current, and the performance making electrothermal relay is influenced by ambient temperature, causes the action of electrothermal relay to produce error.For compensating this impact, being provided with temperature compensating bimetal sheet 13, its material is identical with bimetal leaf 6.When variation of ambient temperature, temperature compensating bimetal sheet produces the additional deformation on same direction with main bimetal leaf, so that the acting characteristic of electrothermal relay is not affected by environment temperature in certain temperature range.This relay construction prevents the shock of sheet metal and fixed mount by arranging buffer spring, the structure preventing relay is damaged, the termination of sheet metal is fixed simultaneously, when sheet deformation is moved more accurate, it is easy to the control to sensitivity, the work making relay can be stablized, solve the existing relay process reaction time slow, in time the heat condition of computer-internal can not be cut off and processes, and easily cause shock to loosen when element moves so that the problem that the structure of relay is damaged.
Bimetal leaf is to be composited by the sheet metal that two kinds of thermal coefficient of expansions are different, and the material of sheet metal mostly is iron-nickel-chromium and iron-nickel alloy.Resistance wire is typically made with the material such as constantan or nichrome.Resetting-mechanism has manually and automatically two kinds of forms, according to requirements can freely adjust selection by the regulation screw that resets.The general automatically reset time is not more than 5min, and the hand-reset time is not more than 2min.Temperature compensating element is also bimetal leaf, and the direction of its heated bending is consistent with bimetal leaf, it is ensured that the acting characteristic of electrothermal relay is not substantially affected by the impact of ambient temperature in the ambient temperature range of 20 DEG C~10 DEG C.The big I of electrothermal relay electric current is regulated by rotatory current knob of adjusting, and i.e. realizes the regulation of size of current by rotating the adjustment runner 21 concentric with adjustment cam 2.
The above; it it is only presently preferred embodiments of the present invention; not the present invention is done any pro forma restriction, every substantially above example is made according to the technology of the present invention, method any simple modification, equivalent variations, within each falling within protection scope of the present invention.
