Abstract

The utility model discloses a temperature and humidity monitor used for a box transformer substation for monitoring the temperature and humidity of a high-voltage room, a transformer room and a low-voltage room of the box transformer substation at the same time. Two temperature sensors and two humidity sensors are independently connected with a single chip microcomputer, and one input setup and one output display are arranged additionally.

Description

Case becomes uses the temperature and humidity monitor device
Affiliated technical field
The utility model relates to a kind of meter specially that case becomes the inner temperature of equipment cabinet, humidity control.This instrument is with digital display monitoring cabinet temperature inside and humidity.
Background technology
At present, be applicable to the temperature and humidity monitor device in the case change, an instrument can only be monitored independent cabinet, and case become the hyperbaric chamber is arranged, three of transformer rooms, low-pressure chamber cabinet independently, then need three instrument that it is monitored respectively, cause cabinet back panel wiring more complicated, occur line fault easily.
Summary of the invention
In order to overcome existing temperature and humidity monitor device wiring complexity, the deficiency of line fault problem appears easily, and the utility model provides a kind of case to become and uses the temperature and humidity monitor device.This utility model can not only reach the purpose of temperature and humidity monitor device, installs but also simplified loaded down with trivial details wiring.
The technical scheme that its technical matters that solves the utility model adopts is: adopt two-way humidity and two-way temperature sensor input temperature-humidity signal, single-chip microcomputer is handled the temperature-humidity signal that receives, show output signal, the humidity in Single-chip Controlling hyperbaric chamber, the temperature of transformer room and the humiture of low-pressure chamber.Set up temperature, humidity higher limit and the overtemperature alarm value that is fit to the device interior environment on their own by the user, when temperature or humidity are higher than higher limit, automatically start blower fan or well heater and come temperature control, dehumidifying, thereby temperature, humidity in the cabinet are controlled in the allowed band, can prevent the too high accident such as creepage that causes that component failure and humidity are too high and cause of temperature in the cabinet effectively.When temperature surpassed the overtemperature alarm value that presets in the cabinet in addition, the overtemperature alarm pilot lamp was bright, and started one group of corresponding switch contact and use for the user.Instrument also has transformer room's fan trouble warning function and transformer room's overtemperature trip avoidance function, when if transformer room's blower fan circuit breaks down, pilot lamp is bright and have one group of switching signal to export, when temperature surpasses the trip temperature value of setting in the cabinet, the tripping operation pilot lamp is bright, and one group of coherent signal output is provided, and this instrument also has outage storage memory function, properties of product are reliable and stable, are applicable to various case variable field institute.
The beneficial effects of the utility model are, become the humiture that can monitor hyperbaric chamber, transformer room, low-pressure chamber with the temperature and humidity monitor device simultaneously with a case, have overcome the wiring complexity simultaneously, occur the problem of line fault easily, reduce cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model circuit theory diagrams.
Fig. 2 is the utility model external wiring diagram.
Fig. 3 is the utility model Face Map.
1 single-chip microcomputer among the figure, 2 temperature-humidity signal, 3 inputs are provided with, and 4 outputs show, 5 control outputs, 6 humidity sensors, 7 temperature sensors, 8 humidity sensors, 9 temperature sensors, 10 dehumidifiers, 11 blower fans, 12 alarms, 13 relays.
Embodiment
In Fig. 1, humidity sensor 6, temperature sensor 7, humidity sensor 8, temperature sensor 9, reception temperature-humidity signal, single-chip microcomputer 1 converts temperature-humidity signal 2 to digital signal, be provided with 3 according to input and handle, and output shows 4.When temperature, humidity are higher than input when 3 higher limits are set, start blower fan, 11 dehumidifying 10 temperature controls and dehumidifying automatically, when in-cabinet temperature surpasses the overtemperature alarm value that presets, overtemperature alarm 12 work.
In embodiment illustrated in fig. 2,1. 2. pin connects the blower fan 11 of transformer room, and 3. 4. pin connects transformer room's overtemperature alarm 12, and 5. 6. pin connects transformer blower fan fault alarm 12, and 7. 8. pin connects hyperbaric chamber dehumidifier 10, and 9. 10. pin connects low-pressure chamber blower fan 11, Pin connects low-pressure chamber overtemperature alarm 12, Pin connects low-pressure chamber dehumidifier 10, Pin connects transformer room's tripping relay 13, Pin connects low-pressure chamber temperature sensor 7, Pin connects low-pressure chamber humidity sensor 6, Pin connects transformer room's temperature sensor 9, Hyperbaric chamber humidity sensor 8, Pin meets 220V and exchanges or direct supply.
Fig. 3 is the instrument face plate synoptic diagram, shows the hyperbaric chamber, transformer room, the controlled show state of low-pressure chamber.

Claims (1)

1. a case becomes and uses the temperature and humidity monitor device, Temperature Humidity Sensor input temperature-humidity signal, single-chip microcomputer is handled the temperature-humidity signal that receives, show output signal, it is characterized in that: adopt the input of two-way temperature and two-way humidity sensor, the humidity in Single-chip Controlling hyperbaric chamber, the temperature of transformer room and the humiture of low-pressure chamber.
