Abstract
The utility model discloses a distributed protector radiator. A refrigerating semiconductor element is arranged outside a distributed protector and seals the distributed protector; an internal wind deflector and an external wind deflector are respectively arranged inside and outside the refrigerating semiconductor element; moreover, ventilation openings are respectively arranged on the upper and the lower sides of both the internal and the external wind deflectors, so that an internal wind channel and an external wind channel are formed; and fans are respectively mounted in the upper and the lower ventilation openings. The distributed protector radiator is also provided with a differential temperature controller in order to control refrigerating output. The distributed protector radiator, which adopts a low-power refrigerating semiconductor element, can precisely and thermostatically control the internal temperature of the protector, so that the elements in the protector can operate under an ideal temperature environment. Meanwhile, since the distributed protector radiator adopts the differential temperature controller to control the refrigerating output, the refrigerating temperature difference can be kept above the dew point, the temperature can be reduced to a set temperature without producing dew, the set temperature can be thermostatically kept, and consequently, when the protector is refrigerated, condensed water cannot be produced. The distributed protector radiator, which has a good refrigerating effect, is generally used in electric power systems, industrial and mining establishments, and the like.
Description
Technical field
The utility model relates to electric power system, industrial and mining enterprises' distributed protective relaying device, relates in particular to the heat radiation of distributed protection device.
Background technology
The distributed protection device is installed in the transformer station hyperbaric chamber; summer the transformer station hyperbaric chamber temperature height (particularly south); high energy reaches more than 42 ℃, and the Normal Environmental Temperature of device work requires below 40 ℃, and optimum temperature is at 25 ℃; normal operation for assurance device; general whole hyperbaric chamber processings of lowering the temperature when adopting cabinet air-conditioner, big owing to the space, hyperbaric chamber, pyrotoxin is arranged; cabinet-type air conditioner will adopt high-power, and ambient temperature can only be reduced to about 35 ℃.Because device all adopts closedly for dustproof, the temperature in the device wants high a lot of with respect to outdoor temperature, and to useful life of device certain influence being arranged, it is bad and energy consumption is high therefore to adopt cabinet-type air conditioner that device is carried out cooling-down effect.
Summary of the invention
The purpose of this utility model is: overcome the above-mentioned defective of prior art, a kind of good cooling results is provided, does not produce condensed water, the radiating control device of the distributed protection device of temperature control sensitivity.
The purpose of this utility model realizes by following scheme: in the device of required radiating control such as distributed protection device periphery the semiconductor refrigerating element is set and the distributed protection device is sealed in it; inside and outside deep bead is set respectively and all offers ventilating opening to form inside and outside air channel inside and outside the enclosing of semiconductor refrigerating element, distinguish up or below ventilating opening installation fan at upper and lower.
The utility model also is equipped with differential temperature controller, the two-way temperature value input of differential temperature controller is arranged at the medial and lateral of the device of required radiating control respectively, with control refrigerating capacity size, guarantee that the refrigeration cool-down temperature difference is beyond dewfall point, dewfall is not until the temperature that reaches setting, and constant temperature remains on design temperature.
The utility model adopts small-power semiconductor refrigerating element; replace a large amount of electric energy of large power air-conditioned saving; be arranged on outside protected device such as the distributed protection crust of the device; owing to must the protection device shell be the thermal conductivity preferably that has of metal; cooling module is by differential temperature controller and fan forced convection; can realize accurate thermostatic control to the device internal temperature; the device inner member is operated in the comparatively ideal temperature environment; adopt differential temperature controller control refrigerating capacity size simultaneously; guarantee the refrigeration cool-down temperature difference beyond dewfall point, dewfall is not until the temperature that reaches setting, and constant temperature remains on design temperature; during the protective device cooling protection; do not produce condensed water, the device good cooling results, specialty is with strong points; temperature controlling there is higher sensitivity, is applicable to electric power system; industrial and mining enterprises etc.
