Description

A kind of hermetically sealed cabinet of external damp-eliminating apparatus
Technical field
The present invention relates to damp-eliminating apparatus fields, more particularly, to a kind of hermetically sealed cabinet of external damp-eliminating apparatus.
Background technique
Various cabinets, including switch mechanism box, terminal box, distribution box of electrical equipment etc., for prevent case in-vivo device by Tide corrosion damages, and insulation reduces short circuit, and the heating of installation heater, cabinet in cabinet is generally taken to open the ventilation appropriate air of mouth up and down The mode of convection current carries out dehumidifying, keeps lower relative humidity in cabinet.Energy consumption is heated to reduce, heater is avoided to add for a long time Heat, the mode of normal reload temperature, humidity controller.With the development of semiconductor refrigerating technology, semiconductor cooling condenser work is carried out For the application that cabinet dehumidifying is dry.
Heater, semiconductor cooling condenser damp-eliminating apparatus, in operation can failure, fever damage, or even short circuit kindling jeopardizes case In-vivo device, there are failure conditions and security risk.Cabinet especially more than segment space relatively narrower or equipment, without suitable Position installation heater or semiconductor cooling condenser, limit the installation of damp-eliminating apparatus.And heater operation in, semi-conductor condensation Device bulk temperature due to electric energy is lost increases, and needs to have appropriately distance with electrical equipment, cable, avoid neighbouring electrical equipment, Cable is heated and accelerated ageing for a long time, shortens the service life, thus occupies space in biggish cabinet.
Heater damp-eliminating apparatus takes non-tight structure, the heater starting time is long, electric energy due to needing cross-ventilation It is lost more, cabinet is easy dust accumulation.Semiconductor cooling condenser dehumidifying, needs that condensed water is discharged, and needs that drainpipe is arranged in cabinet, to It is drained outside cabinet;Drainpipe is easy incrustation after a long time, causes impeded drainage, increases the workload of drainpipe cleaning, and is easy Condensed water is caused to accumulate in the bottom of box.
Damp-eliminating apparatus is mounted in cabinet, and the walkaround inspection of damp-eliminating apparatus needs to open cabinet, the moist, rainy day, will cause Moisture enters, and increases dust accumulation amount.How the high cabinet of safety requirements, the mode for often taking locking to protect, check after locking Whether damp-eliminating apparatus is normal, and there are contradictions.
Summary of the invention
The present invention is that damp-eliminating apparatus in the above-mentioned body of electric component box in the prior art is overcome to cause to occupy housing interior volume, Unpacking, attended operation is cumbersome, and the undesirable defect of the effect of built-in dehumidifying provides a kind of hermetically sealed case of external damp-eliminating apparatus Body.
Primary and foremost purpose of the invention is in order to solve the above technical problems, technical scheme is as follows:
A kind of hermetically sealed cabinet of external damp-eliminating apparatus, comprising: hermetically sealed case ontology, damp-eliminating apparatus, the damp-eliminating apparatus It is set on the alien invasion of hermetically sealed case ontology, the damp-eliminating apparatus is connected to hermetically sealed case ontology by exhaust pipe and air intake duct It is internal.The present invention overcomes conventional internal formula dehumidifying and occupies case by the way that damp-eliminating apparatus to be arranged in the alien invasion of hermetically sealed cabinet The defect of body inner space, at the same by air intake duct draw the humid air of hermetically sealed box house after damp-eliminating apparatus is dry by Exhaust pipe discharge, the dehumidifying for realizing hermetically sealed box house are dry.It should be noted that hermetically sealed cabinet only passes through air intake duct The circulation of air is carried out with exhaust pipe, other positions of hermetically sealed cabinet do not set cross-ventilation mouth.
Further, the damp-eliminating apparatus includes: damp-eliminating apparatus ontology, condenser, exhaust pipe, air intake duct, the row One end of tracheae is connected to damp-eliminating apparatus body interior, and the other end is connected to hermetically sealed case body interior, and the one of the air intake duct End is connected to damp-eliminating apparatus body interior, and the other end is connected to hermetically sealed case body interior, and the condenser is placed in damp-eliminating apparatus Body interior.
Further, Temperature Humidity Sensor is additionally provided with inside the damp-eliminating apparatus.The air-breathing that the present invention passes through damp-eliminating apparatus Pipe sucks the air of hermetically sealed box house, and in damp-eliminating apparatus body interior sealing space, the Temperature Humidity Sensor is directly surveyed The temperature and humidity of amount sucking air, that is, characterize the current temperature and humidity of seal case.
Further, the damp-eliminating apparatus is additionally provided with the first work light, the second work light.
Further, first work light is normal run indicator, and second work light is abnormal Indicator light.The current operation of damp-eliminating apparatus can more be got information about by operating normally indicator light and abnormal indicator light by setting State.
Further, the condenser is semiconductor cooling condenser.It should be noted that in damp-eliminating apparatus in addition to condenser not Other heating devices are set, the hidden danger that the dehumidifying dehumidifying of traditional heating formula is caught fire by hot-spot is eliminated.
Further, the condenser is preset with condenser control program.Program is controlled by preset condenser to control Refrigeration condenser starts and stops, it should be noted that case when the parameter of control process control includes but is not limited to condenser starting Body temperature, humidity value, case body temperature, humidity value when condenser stops.
Further, the damp-eliminating apparatus is fixed on hermetically sealed cabinet alien invasion by bolt or buckle.
Further, the damp-eliminating apparatus using in hermetically sealed cabinet power supply or hermetically sealed cabinet outside power.Supplier of electricity Formula can flexible choice.
Hermetically sealed cabinet is taken, the convection current ventilation of air, does not reduce the dust accumulation of cabinet, is conducive to keep case in-vivo device Cleaning;Do not take a breath, enter without external humidification, greatly reduce the starting dehumidifying of semiconductor cooling condenser in damp-eliminating apparatus when Between, reduce electric energy loss.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
The present invention by by damp-eliminating apparatus be placed outside hermetically sealed cabinet alien invasion overcome occupy housing interior volume lack It falls into, damp-eliminating apparatus is external need not to open seal case in maintenance, avoid external humidification from entering, while hermetically sealed cabinet does not have Just whether outside air convection improves the effect of hermetically sealed box house dehumidifying, can check damp-eliminating apparatus without chamber door is opened Often.
