Abstract
The invention discloses a dehumidification type emergency power supply cabinet. The dehumidification type emergency power supply cabinet comprises a cabinet body, two charge devices, a battery pack, an inverter, a controller, an input terminal and an output terminal, and further comprises a dehumidification device, wherein the charge devices, the battery pack, the inverter, the controller, the input terminal and the output terminal are arranged in the cabinet body, the input terminal is used for input, the output terminal is used for output, and the dehumidification device is composed of a relative temperature sensor, a triode, a relay, a single-chip microcomputer and a semiconductor cooler. The signal output end of the relative temperature sensor is connected with a P0 port of the single-chip microcomputer, the base of the triode is connected to an P3 port of the single-chip microcomputer, the emitting electrode of the triode is connected to a control coil of the relay, and the normally-open contact of the relay is connected with a direct-current power supply in series, and the direct-current power supply supplies power to the semiconductor cooler. The semiconductor cooler is arranged in the cabinet body, and therefore moist air in the high-frequency switching power supply cabinet body is condensed and coagulated only on the cooling surface of the semiconductor cooler and then discharged out of the cabinet body, and the moisture content of the moist air in the cabinet body is lowered.
Description
?
Technical field
The present invention relates to power cabinet technical field, be specifically related to a kind of dehumidification type emergency power supply cabinet.
Background technology
Power plant, Deng Gong distribution department of transformer station (institute) be the uninterrupted power supply as devices such as control, signal, protection, emergency lighting, direct current oil pump, divide-shut brakes with accumulator direct current supply conventionally, and whether continuous-current plant reliably directly has influence on the safe operation of power supply-distribution system.
DC power cabinet has been widely used in the fields such as telecommunications, electric power, oil, once electric main breaks down, high-frequency switch rectifying power supply will lean on its standby battery group to maintain the power supply to DC load, and the discharge time of batteries is limited, not president's time sustain discharge.In existing DC power cabinet, between several charging devices, there is the problem of electric current reverse flow.
In order to guarantee the normal of power cabinet, except need stop that toy enters, waterproof, anti-corrosion, also to prevent that power cabinet from making moist.At present, the power cabinet problem of making moist never obtains fine solution, especially Shelter in South China Cities.For waterproof, the cabinet door of power cabinet generally all has good sealing property, but also can cause its inner moisture not discharge fast like this, especially in rainy season or in the larger area of relative air humidity.When the humid air in power supply cupboard case reaches dew point temperature, be just easy to dewfall in case, cause its decreasing insulating, when serious, insulator surface also can produce electric discharge, causes the generation of power equipment malfunction or tripping accident.In order to prevent dewfall in power cabinet, heater has been installed additional in power cabinet inside in some transformer stations, wish that the temperature by improving in terminal box stops water recovery, but effect is not satisfactory.
Summary of the invention
For above-mentioned prior art, the object of the invention is to, a kind of dehumidification type emergency power supply cabinet is provided, and the electronic devices and components surface sweating that is intended to solve high frequency switch power cabinet cabinet internal condensation and high frequency switch power cabinet power cabinet inside causes the on-insulated problem of high frequency switch power cabinet.
