Abstract
The utility model discloses a fire water supply equipment control cabinet with an automatic dampproof dehydrating device, and belongs to the manufacturing technical field of the cabinet. The control cabinet comprises a main loop including a duplicate power conversion circuit and a low voltage electrical device, a detector arranged on the upper part in the control cabinet and a dehydrating heater arranged on the bottom part inside the control cabinet. Inflaming retarding twisted pair cable is adopted between the detector and the dehydrating heater. The environment of a fire water pump house is often damp, with the relative humidity exceeding 90 percent, to this degree moisture concentration can happen, so that the normal operation of the water supply equipment control cabinet in the pump house is threatened. In order to overcome the impact of the condition to the fire water supply equipment control cabinet, the automatic dampproof hydrating device, which can automatically detect the temperature and the humidity inside the cabinet, automatically conduct dehydration and heating, and reliably ensure the working environment of the control cabinet, is added in the control cabinet.

The utility model content
In order to overcome the deficiency of existing technology, the utility model has solved fire water pump house high humidity, a kind of fire water supply equipment switch board with automatic moistureproof dehydrating unit that the water work switch board can't the operate as normal design in the pump house.
The utility model comprises: the major loop that dual power supply conversion line and low-voltage electrical apparatus are formed, it is characterized in that: detector is installed at described switch board inner top, bottom in switch board is equipped with the dehumidifying heater, adopts fire-retardant twisted-pair feeder to connect between detector and the dehumidifying heater.
Comprise the probe, digital circuit and the relay group that are electrically connected successively in the described detector, described probe, digital circuit and relay group are powered by power circuit, and the outside of described detector is a detector housing.
Described dehumidifying heater is made up of ceramic heating flake, the fire-retardant lead that links to each other with ceramic heating flake and dehumidifying heater housing.
On the cabinet front panel of described switch board voltmeter, ammeter, indicator lamp and button are installed.
Described detector housing is the netted shell that helps breathing freely.
The meshed anode aluminium shell that described dehumidifying heater housing for the benefit of dispels the heat.
Described probe is made up of semi-conducting material and metal heat-sensing device.
The utlity model has following beneficial effect: the fire water supply equipment switch board that the utility model provides with automatic moistureproof dehydrating unit, in switch board, installed the device of automatic moistureproof dehumidifying additional, automatically the humiture in the detecting box, and dehumidify automatically and heat, guarantee the working environment of switch board reliably.
Description of drawings
Fig. 1 is the utility model switch board overall schematic;
Fig. 2 is the utility model internal structure schematic diagram.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.Fig. 1 is the utility model switch board overall schematic, comprise the major loop that the dual power supply conversion line that is installed in cabinet the inside and low-voltage electrical apparatus are formed, at described switch board inner top detector 1 is installed, bottom in switch board is equipped with dehumidifying heater 2, adopts fire-retardant twisted-pair feeder 11 to connect between detector 1 and the dehumidifying heater 2.
Fig. 2 is the utility model internal structure schematic diagram, above big frame table shows is internal structure schematic diagram in the detector 1, below big frame table shows is the internal structure schematic diagram of dehumidifying in the heater 2, adopt fire-retardant twisted-pair feeder 11 to connect between detector 1 and the dehumidifying heater 2.Comprise the probe 3, digital circuit 4 and the relay group 6 that are electrically connected successively in the detector 1, probe 3, digital circuit 4 and relay group 6 are by power circuit 5 power supplies, and the outside of detector 1 is a detector housing 7.Dehumidifying heater 2 is made up of ceramic heating flake 8, the fire-retardant lead 9 that links to each other with ceramic heating flake 8 and dehumidifying heater housing 10.On the cabinet front panel of described switch board voltmeter, ammeter, indicator lamp and button are installed.The netted shell of detector housing 7 for helping breathing freely.The meshed anode aluminium shell that dehumidifying heater housing 10 for the benefit of dispels the heat.Probe 3 is made up of semi-conducting material and metal heat-sensing device.
The degree of protection of the utility model cabinet: IP=55, outside the structure of the syndeton of the major loop that dual power supply conversion line, low-voltage electrical apparatus are formed and voltmeter, ammeter, plurality of indicator lamps and button on the cabinet front panel, a detector 1, be used for the temperature and humidity in the real-time detecting box, and in real time detected value and setting value compared.When the humidity in the cabinet greater than when setting value, this detector 1 provides the signal of telecommunication, these signal of telecommunication control dehumidifying heater 2 work.The work of dehumidifying heater 2 makes wetness decline in the cabinet, or be lower than zero when Celsius when in-cabinet temperature, also can make 2 work of dehumidifying heater, and make in-cabinet temperature be elevated to normal value, when in-cabinet temperature and humidity reach normal value (setting value of detector 1), detector 1 provides the signal of telecommunication, and this signal of telecommunication quits work dehumidifying heater 2.So, can guarantee temperature and humidity in the cabinet, make under electronic device in the cabinet, the environment that low-voltage electrical apparatus is operated in normal humiture that assurance equipment normally moves in normal range (NR).
