The specific embodiment
Understand for technical characterictic, purpose and effect to utility model have more clearly, now contrast the description of drawings specific embodiment of the present utility model, identical label represents identical part in each figure.
In this application, " thermal insulation " or " heat insulation " is not that expression thoroughly and is fully kept apart heat, as long as effect of heat insulation can accept on engineering, such as the lower general thermal insulation material of employing coefficient of thermal conductivity, such as polyurethane foam board or centrifugally peel off cellucotton/rock wool.
Although on switch machine, can adopt infrared mode to heat because the heat efficiency of this mode is not high, and infrared facility to take volume larger, be not easy to use at switch machine.And in order to guarantee that point machine can use in the cold wet area, the utility model provides a kind of heating arrangement that uses the switch machine of resistor.
In a kind of embodiment of the present utility model, as shown in Figure 1, the heating arrangement 100 of switch machine comprises a resistor 10, a radiator 50 and a support 30, wherein: radiator 50 is fixed on the resistor 10, and resistor 10 or radiator 50 by support 30 thermal insulations be fixed in the switch machine, as shown in Figure 2, an arm 302 by support 30, just heating arrangement 100 can be fixed in the switch machine, like this, the heat that resistor 10 produces then can heat the air in the switch machine quickly, so that quickly temperature rising of some little spaces in the switch machine.
By additional external power supply (for example: single-phase ac power supply can allow voltage to have larger fluctuation to change) is provided to point machine, resistor 10 two ends are arranged a voltage, thereby resistor 10 converts electric energy to heat energy.And the radiator 50 convenient heats that resistor 10 is produced carry out the heat transfer in cross-ventilated mode, thereby add hot air.
Simultaneously, if the heating arrangement that is arranged in the switch machine needs ceaselessly operation in 24 hours, and the working temperature range of resistance nominal has a higher limit, ° C for example+125, untimely if dispel the heat, thereby the situation of overheated scaling loss may appear in resistance, then can effectively increase heat exchange action between resistor and the ambient cold air medium such as the radiator of fan or radiating gill etc., avoids resistor to burn out.
In a kind of embodiment of the present utility model, as shown in Figure 5, the radiating gill 510 of radiator 50 vertically arranges, because the always bottom-up motion of air-flow of heat, the groove 511 of radiating gill 510 is vertically arranged, help thermal current to rise, thereby in the inner convection current diffusion that forms the part of switch machine.
In other a kind of embodiment of the present utility model, as shown in Figure 4, be provided with extraly a protective cover 20 on the heating arrangement 100, be arranged on radiator 50 outsides protective cover 20 half parcels, on the one hand protective cover 20 has had an open portion at least, and be convenient to the heat that heating arrangement produces and pass through, thus the local space of circumference, in addition on the one hand, protective cover 20 also plays isolation, prevents that human body from being burnt and the protective action when unexpected the electric leakage occurring.
In another embodiment of the present utility model, shown in Fig. 1,3,5, be provided with extraly a cleading 40 in the heating arrangement, resistor 10 or radiator 50 are fixed on the support 30 by cleading 40, and then are fixed in the switch machine by support 30.
The purpose that cleading 40 is set is to avoid the heat with resistor 10 directly to reach on the drain pan of switch machine, so that the basal temperature of drain pan rises, because the purpose of this utility model is not in order to heat switch machine itself, but in order to add hot air.40 of cleadings make heat that resistor 10 and radiator 50 give out mainly carry out heat by the mode of circulating air and radiation and shift, and avoid being directly transferred on the switch machine parts and reduce heating effect.If a power is about tens watts resistor and the drain pan of switch machine directly links to each other, the heat of this part that resistor can produce can promptly be absorbed by drain pan, and the condensation of switch machine mainly occurs in the little space of switch machine inside, contact such as some electrical connections, if heat has been absorbed by drain pan, the heat energy of then launching in the air can significantly descend, heat just can not reach so very little space, contact surface, reduces owing to the switch machine inner body freezes to cause the possible effect of fault appearance just can be affected.
Certainly, also can allow the switch machine entire body all heat, but need very large heat like this, the electric energy of consumption also can significantly improve.
More preferably, cleading has the function of electrical isolation simultaneously, can prevent that the resistor electric leakage from conducting on the switch machine, avoids the personal injury that causes because of electric leakage.
What can expect is, cleading can be set, also can achieve the above object, such as limiting by the material to support, resistor 10 or radiator 50 by the support thermal insulation be fixed in the switch machine, that is to say that the holder part that contacts with resistor 10 or radiator 50 is thermal insulation material, as long as guarantee that this material can adapt to the residing vibration environment of switch machine, assurance can stably be fixed in the switch machine and get final product.
In further a kind of embodiment of the present utility model, shape to support provides more specifically description, such support has a T-shaped or L-type shape, and resistor 10 or radiator 50 are arranged on the arm of T-shaped or L-type support (as shown in Figure 5, resistor 10 just is arranged on the arm 301 of support 30).An arm of the support that so also can will contact with resistor 10 or radiator 50 is arranged to thermal insulation material more conveniently.
Certainly, resistor 10 or radiator 50 also can be arranged on two arms of T-shaped or L-type support or on the more arm, but, need so also to guarantee that resistor 10 or radiator 50 can be arranged on switch machine inside heat insulationly, that is to say, need between resistor 10 or radiator 50 and support 30, cleading 40 be set, perhaps, support 30 parts that contact with resistor 10 or radiator 50 should be thermal insulation material and make, like this, the heat on resistor 10 or the radiator 50 just can directly not reach on the switch machine.
The utility model also provides a kind of switch machine, and described switch machine comprises an as above described switch machine heating arrangement of any one, and it is inner to be fixed on to described heating arrangement thermal insulation described switch machine.
Because by resistor and radiator, the convection current that utilizes heat and radiation effect rather than contact the mode of conduction, thus can heat the air themperature of switch machine inside, thus it is icing to realize eliminating the piece surface condensation.Even in the cold wet area, when variation of ambient temperature during large or sudden change, it also can effectively prevent contact surface condensation, frosting, thereby avoids the contact adhesion that causes thus, the fault that conversion freely can not in time not provide the expression signal, guarantees the high efficiency of railway operation.
In this article, " schematically " expression " is served as example, example or explanation ", any diagram, the embodiment that is described in this article " schematically " should be interpreted as a kind of preferred or have more the technical scheme of advantage.
Above listed a series of detailed description only is specifying for feasibility embodiment of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent embodiment or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
