Principium scelerisque Fuse

A scelerisque fuse vel scelerisque cutoff est salus fabrica quod aperto circuitus contra overheat. Hoc deprehenderit calorem fecit per-current ex brevi circuitu vel component naufragii. Thermal fuses non reset se cum temperatus guttas sicut circuitus ruptor. A scelerisque fuse debet reponi cum deficit vel Urguet.
Dissimilis electrical fuses aut circuitus, scelerisque fuses tantum reflecti ad nimia temperatus, non nimia current, nisi nimia vena est sufficiens ad causam ad scelerisque fuso ad calefacere ad trigger ad inducere modum in usu ad calefacere in exemplum et lectio in modum in practical applicationem.
I. Function of scelerisque Fuse
Et scelerisque fuse est maxime composito ex fusant, liquescens fistulam et externum filler. Cum in usu, in scelerisque fuse potest sensu abnormes temperatus ortum electronic products, et temperatus sentitur per pelagus corpus de scelerisque fuse et filum. Cum temperatus pervenit ad liquescens punctum ad conflandum, et fusant mos automatically conflandum. Superficiem tensio liquefactum fusant est auctus sub promotionem speciali fillers, et fusant fit sphaerica post liquescens, ita incidit circuitu vitare ignis. Ensure tutum operationem electrica apparatu coniuncta ad circuitu.
II. Opus principium de scelerisque Fuse
Sicut specialis fabrica ad overheating praesidium, scelerisque fuses potest amplius divisa in organicum scelerisque fuses et mixta scelerisque fuses.
Inter eos, organicum scelerisque fuse est composito de mobili contactum, fusant et spring.Before organicum type scelerisque fuse est activated, vena fluit ab uno ducere per mobile contactus et per metallum curvam ad alterum plumbum. When the external temperature reaches the preset limit temperature, the fusant of the organic matter will melt, causing the compression spring device to become loose, and the expansion of the spring will cause the movable contact and one side lead to separate from each other, and the circuit is in an open state,then cut off the connection current between the movable contact and the side lead to achieve the purpose of fusing.
Alloy Type scelerisque Fuse ex filum, fusant, specialis mixtisque, testa et signa resina. Sicut in circuitu (ambientium) temperatus resurget, specialem mixturam incipit ad liquefy. When the surrounding temperature continues to rise and reaches the melting point of the fusant, the fusant begins to melt, and the surface of the melted alloy produces tension due to the promotion of the special mixture,using this surface tension, the melted thermal element is pilled and separated to both sides, to achieve a permanent circuit cut. Fusibile Alloy scelerisque fuses capaces occasum variis operating temperaturis secundum fusant compositionem.
III. Quam eligere scelerisque Fuse
(I) et rated operationem temperatus de delectis scelerisque fuse debet esse minus quam temperatus resistentia gradu de materia propter electrica apparatu.
(II) et rated current de delectae scelerisque fuse sit ≥ in maximam operantes current de protected apparatu vel components / vena post reductionem rate. Assumens quod opus vena est circuitus est 1.5a, in rated current de delectis scelerisque fuse ut pervenire 1.5 / 0,72, id est, magis quam 2.0a, ut reliability ad scelerisque fuse fusing ad curare.
(III) et rated current de lectus scelerisque fuse scriptor fusant ne ad apicem current de protected apparatu vel components. Only by satisfying this selection principle can it is ensured that the thermal fuse will not have a fusing reaction when a normal peak current occurs in the circuit.In particular, if the motor in the applied circuit system needs to be started frequently or braking protection is required, the rated current of the fusant of the selected thermal fuse should be increased by 1 ~ 2 levels on the basis of avoiding the peak current of the protected device or component.
(IV) et fusant scriptor rated voltage of lectus scelerisque fuse erit maior quam ipsa circuitus intentione.
(5) The voltage drop of the selected thermal fuse shall conform to the technical requirements of the applied circuit.This principle can be ignored in high voltage circuits, but for low voltage circuits, the influence of voltage drop on fuse performance must be fully evaluated when selecting thermal fuses because voltage drop will directly affect circuit operation.
(VI) et figura de scelerisque fuse debet esse electus secundum figura de protected fabrica. For example, the protected device is a motor, which is generally annular in shape,the tubular thermal fuse is usually selected and inserted directly into the gap of the coil to save space and achieve a good temperature sensing effect.For another example, if the device to be protected is a transformer, and its coil is a plane, a square thermal fuse should be selected, which can ensure better contact between the thermal fuse and the coil, so as to achieve a better tutela effectus.
IV. Praecautions pro usura scelerisque fuses
(I) Sunt clara ordinationes et limitations ad scelerisque fuses in terms of rated current, rated voltage, operating temperatus, fusing temperatus, maximum lectus et alia requisitis, quae opus est ut flexibly lectus sub praemissa est ut sit mollius electus in praemissa est ut sit mollius electus sub praemissa est ut sit mollius lectus in praemissa est quod opus est ut mollius electus in praemissa est ut sit mollius electus sub praemissa est ut elit.
(2) Special attention must be paid to the selection of the installation position of the thermal fuse, that is, the stress of the thermal fuse should not be transferred to the fuse due to the influence of the position change of the key parts in the finished product or vibration factors, so as to avoid adverse effects on the overall operation performance.
(III) In ipsa operatio de scelerisque fuse, necesse est ut install in casu ut temperatus est adhuc minus quam maximam licita temperatus post Fuse est.
(IV) Installation situ de scelerisque Fuse est in instrumento vel apparatu cum humiditas altior quam 95.0%.
(5) In terms of installation position,the thermal fuse should be installed in a place with good induction effect.In terms of installation structure, the influence of thermal barriers should be avoided as much as possible,For example, it shall not be directly connected and installed with the heater, so as not to transfer the temperature of the hot wire to the fuse under the influence of heating.
(VI) Si enim scelerisque fuse in parallel vel continuously affectus per overvoltage et overcurrent factors, quod abnormes amount of internum current ut faciam damnum ad internum et inefficit ad normalem operationem totius scelerisque fuse afficiunt. Ideo usum huius generis fuse non commendatur sub supra condiciones.
Although the thermal fuse has high reliability in design, the abnormal situation that a single thermal fuse can cope with is limited,then the circuit cannot be cut off in time when the machine is abnormal.Therefore, use two or more thermal fuses with different fusing temperatures when the machine is overheated, when a faulty operation directly affects the human body, when there is no circuit cutting device other than a fuse, and when a high degree de salute requiritur.
