Description
Technical field
The utility model relates to a kind of multifunctional digital electric instrument that has Temperature and Humidity Control, belongs to the power measure meters field.
Background technology
At present; Conventional multifunctional digital electric instrument does not have all that the temperature degree detects, control function, and the environment for use of electric instrument is changeable and complicated, especially at the plum rain season of the south of the lower reaches of the Yangtze River; Moist weather makes the gauge internal short circuit easily, thereby influences the serviceable life of instrument; Simultaneously, under high-temperature conditions such as summer, lack corresponding monitoring temperature and also make instrument Yin Gaowen easily and burn, even accident such as initiation fire.Simultaneously; Electric instrument generally is installed in the power distribution cabinet; The tie point of electrical equipment often causes the overtemperature heating or punch-through takes place because of humidity is excessive easily because of the influence of factors such as loop load, mounting process, tie point equipment material in the power distribution cabinet; Thereby power distribution cabinet need install temperature and humidity controller in-cabinet temperature is monitored, thereby increased user's use cost.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of multifunctional digital electric instrument with Temperature and Humidity Control function is provided.
The purpose of the utility model is achieved in that a kind of multifunctional digital electric instrument that has Temperature and Humidity Control; Said instrument includes microprocessor, temperature sensor and humidity sensor, and said temperature sensor and humidity sensor link to each other with microprocessor behind temperature sampling circuit and humidity sample circuit respectively.
The utility model has the multifunctional digital electric instrument of Temperature and Humidity Control, is connected with thermorelay and humidity pilot relay on the said microprocessor, and said thermorelay links to each other with well heater with fan respectively with the humidity pilot relay.
The utility model has the multifunctional digital electric instrument of Temperature and Humidity Control, also is connected with a plurality of electric energy control relays on the said microprocessor.
The utility model has the multifunctional digital electric instrument of Temperature and Humidity Control, also is connected with the A/D change-over circuit on the said microprocessor, and said A/D change-over circuit links to each other with voltage sampling circuit with current sampling circuit.
Compared with prior art, the beneficial effect of the utility model is:
Behind the utility model electric instrument reload temperature sensor and the humidity sensor; Can detect ambient temperature and humidity in real time; When finding to exceed standard; Also can regulate and control local humiture, optimize the working environment of instrument greatly, help improving the precision of detection, the serviceable life of prolongation instrument through thermorelay and humidity pilot relay; Simultaneously, instrument carries the Temperature and Humidity Control function, thereby need not to install separately more corresponding temperature and humidity controller in the power distribution cabinet in use, greatly reduces user's use cost.
