Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited only to this.
Embodiment 1:
As shown in Figure 1, based on the thermal relay structure used in computer operation control, comprise some pieces of bimetal leafs 6 arranged in parallel, the bottom of described bimetal leaf 6 is provided with fixed mount 9, guide plate 8 is provided with between fixed mount 9 and bimetal leaf 6, the bottom of guide plate 8 is fitted on fixed mount 9, guide plate 8 can move horizontally along fixed mount 9, the top indent of guide plate 8 forms several grooves, the bottom correspondence of bimetal leaf 6 is arranged in a groove, resistance wire 7 is provided with between adjacent bimetal leaf, resistance wire 7 one end connects with corresponding bimetal leaf 6 respectively, one end of guide plate 8 is connected with push rod 12, push rod 12 is connected with compensation bimetal leaf 13 away from one end of guide plate 8, the top compensating bimetal leaf 13 is connected with push rod 3, push rod 3 one end is connected with connecting rod 17, connecting rod 17 is connected with adjustment cam 2 and Compress Spring 1, and connecting rod 17 is arranged between adjustment cam 2 and Compress Spring 1, push rod 3 is connected with sheet spring 16 away from one end of connecting rod 17, sheet spring 16 is connected with moving contact 11, bow spring 5 and manual reset button 4, and bow spring 5 is connected with moving contact 11, fixed contact 10 is provided with between moving contact 11 and bimetal leaf 6, and fixed contact 10 is arranged on above guide plate 8, compensate between bimetal leaf 13 and moving contact 11 and be provided with reset adjustment screw 14, and the termination of reset adjustment screw 14 is near compensating bimetal leaf 13, reset adjustment screw 14 is arranged on the top of push rod 12, described push rod 3, in L-type structure, 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 is simultaneously through push rod 3 and connecting rod 17, and push rod 3 can rotate around rotating shaft 15.In the technical program, preferential employing three pieces of bimetal leafs 6, between adjacent bimetal leaf 6, resistance wire 7 is set, push rod 12 and fixed contact 10 are all near leftmost bimetal leaf 6, during use, be serially connected in the three-phase main circuit of computer respectively by the three-phase thermal element of thermal 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 thermal relay, and resistance wire 7 generates heat, and bimetal leaf 6 bends to the right; promote guide plate 8 to move right; make push rod 12 pull compensation bimetal leaf 13 to move, promote push rod 3 15 rotations around the shaft by compensating bimetal leaf 13, thus promote contact system action; moving contact separates with dynamic circuit breaker fixed contact; make contactor coil power-off, contacts of contactor disconnects, and power supply excision is shielded.After power supply excision, bimetal leaf 6 cools gradually and sets back, so moving contact is when ineffective power, automatically resets by the elasticity of bending spring 5.This thermal relay also can adopt hand-reset, again puts into operation with equipment belt fault before preventing failture evacuation.Reset adjustment screw 14 is outwards adjusted to certain position, and the rotation making moving contact bend spring exceedes certain angle and loses least, even if now main bimetal leaf cooling is restored, moving contact can not automatically reset, and must adopt hand-reset.Press reset button, moving contact bow spring returns to has flexible angle, and promotion moving contact and fixed contact recover closed.When variation of ambient temperature, can there is null offset in bimetal leaf 6, and namely thermal element does not produce distortion by bimetal leaf main during electric current, makes the performance of thermal relay influenced by ambient temperature, causes the action of thermal relay to produce error.For compensating this impact, be provided with temperature compensating bimetal sheet 13, its material is identical with bimetal leaf 6.When variation of ambient temperature, temperature compensating bimetal sheet and main bimetal leaf produce the additional deformation on same direction, thus make the operating characteristics of thermal relay in certain temperature range substantially not by the impact of ambient temperature.Adopt this thermal relay structure, can Reaction time shorten greatly, computer just can be controlled in time at discovery adstante febre, computer-internal element is avoided to be burnt out, solve existing relay to detect computer-internal occur after, its processing reaction time is slow, can not cut off the heat condition of computer-internal and process in time, cause the problem that computer components burn out.
Bimetal leaf is 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 generally made with the material such as constantan or nichrome.Resetting device has manually and automatic two kinds of forms, according to requirements freely can adjust selection by reset adjustment screw.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 can ensure the operating characteristics of thermal relay DEG C ~ ambient temperature range of 10 DEG C in substantially not by the impact of ambient temperature.The size of thermal relay electric current regulates by rotatory current knob of adjusting, and namely realizes the adjustment of size of current by rotating adjustment cam 2.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; every according to technology of the present utility model, method in fact to any simple modification, equivalent variations that above embodiment is done, all fall within protection range of the present utility model.
