The utility model discloses a WSK atmospheric control ware, but its simple to operate default temperature control range just can show humiture numerical value in real time.

Description

The temperature and humidity intelligent control circuit of preassembled transformer station

Technical field

The utility model relates to a kind of temperature and humidity intelligent control circuit of preassembled transformer station.

Background technology

At present, there is the preassembled transformer station of temperature and humidity regulation function, generally need mounting temperature sensor, humidity sensor, controller etc., electric component is more, install and comparatively bother, and need burning program on the controller to carry out preset temperature range of adjustment, operation comparatively bothers.

Utility model content

Technical problem to be solved in the utility model is, provide a kind of temperature and humidity intelligent control circuit of preassembled transformer station, it adopts WSK temperature and humidity controller, its easy for installation, predeterminable temperature regulating range and can show humiture numerical value in real time.

For solving the problems of the technologies described above, the temperature and humidity intelligent control circuit of the preassembled transformer station that the utility model provides, it comprises the WSK temperature and humidity controller, contactor KM1, contactor KM2, several blower fans and several electric boiling plates that are installed on preassembled transformer station inside, the coil of contactor KM1 and the coil of contactor KM2 are serially connected on two control loops of WSK temperature and humidity controller respectively, and the normally opened contact of contactor KM1 and the normally opened contact of contactor KM2 are serially connected on the current supply circuit of blower fan and electric boiling plate respectively.

As preferably, with electric power generating composition current supply circuit after the coil of described contactor KM1 and the coil of contactor KM2 are in parallel, rotary switch SA is serially connected on this current supply circuit.

As preferably, it also comprises several illuminating lamps being installed on preassembled transformer station inside, and switchette QF2 and light switch HA is serially connected on the current supply circuit of illuminating lamp successively.

As preferably, it also comprises the unidirectional socket be installed on preassembled transformer station, and switchette QF1 is serially connected on the current supply circuit of single-phase socket.

As preferably, described unidirectional socket has two and the setting that is in parallel.

After adopting above structure, the utility model compared with prior art, has following advantage:

WSK temperature and humidity controller is for preventing condensation from occurring and a kind of automatic industrial instrument of predeterminable ambient temperature range, it has two relatively independent working cells, one tunnel humidity control, one road monitoring temperature, also multichannel Temperature and Humidity Control can be had, it utilizes the advanced humiture index of sensor to working environment automatically to monitor for a long time, sample, the feature such as have life-span long, easy for installation, operation and display position is concentrated; Like this, when temperature and humidity control system being installed in this preassembled transformer station, only need this WSK temperature and humidity controller is installed, this WSK temperature and humidity controller can monitor the humiture in preassembled transformer station, install more for convenience, and this WSK temperature and humidity controller has the function of preset temperature range of adjustment, can, directly by pressing key assignments, operate comparatively easy; And this WSK temperature and humidity controller also has display screen, can display environment humiture numerical value in real time.

Accompanying drawing explanation

Fig. 1 is circuit structure diagram of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

As shown in Figure 1, the temperature and humidity intelligent control circuit of the utility model preassembled transformer station comprises the WSK temperature and humidity controller being installed on preassembled transformer station inside, contactor KM1, contactor KM2, several blower fans and several electric boiling plates, three-phase alternating-current supply is that WSK temperature and humidity controller is powered by fuse FU, the coil of contactor KM1 and the coil of contactor KM2 are serially connected on two control loops of WSK temperature and humidity controller respectively, the normally opened contact of contactor KM1 and the normally opened contact of contactor KM2 are serially connected on the current supply circuit of blower fan and electric boiling plate respectively, when detecting that the humidity in preassembled transformer station exceedes setting value, the coil of WSK temperature and humidity controller control contactor KM2 obtains electric, the normally opened contact of contactor KM2 is closed, make electric boiling plate energising work, electric boiling plate generates heat, can prevent from producing condensation in preassembled transformer station, when the temperature in preassembled transformer station being detected lower than setting value, the coil of WSK temperature and humidity controller control contactor KM2 obtains electric, the normally opened contact of contactor KM2 is closed, make electric boiling plate energising work, electric boiling plate generates heat, temperature in preassembled transformer station is raised, avoids the electric component bursting by freezing in preassembled transformer station impaired, when the temperature in preassembled transformer station being detected higher than setting value, the coil of WSK temperature and humidity controller control contactor KM1 obtains electric, the normally opened contact of contactor KM1 is closed, make blower fan energising work, blower fan to make in preassembled transformer station temperature reduce, avoid the electric component in preassembled transformer station due to temperature too high and damage.

With electric power generating composition current supply circuit after the coil of described contactor KM1 and the coil of contactor KM2 are in parallel, rotary switch SA is serially connected on this current supply circuit, like this, when needed, can obtain electric by the coil of the coil of rotary switch SA Non-follow control contactor KM1 and contactor KM2, make blower fan and electric boiling plate work.

It also comprises several illuminating lamps being installed on preassembled transformer station inside, switchette QF2 and light switch HA is serially connected on the current supply circuit of illuminating lamp successively, like this when needing illumination in preassembled transformer station, switchette QF2 and light switch HA is closed, illuminating lamp can be made to be energized shinny, think in preassembled transformer station and illumination is provided.

It also comprises the unidirectional socket be installed on preassembled transformer station, switchette QF1 is serially connected on the current supply circuit of single-phase socket, described unidirectional socket has two and the setting that is in parallel, like this, when preassembled transformer station needs externally to provide emergency power pack, closed by switchette QF1, this unidirectional socket CZ1 and unidirectional socket CZ2 obtains electric, and plug can insert power taking in unidirectional socket.

Below only apply preferably example with regard to the utility model and made explanation, but can not be interpreted as it is limitations on claims, structure of the present utility model can have other to change, and is not limited to said structure.In a word, all various changes done in the protection domain of independent claims of the present utility model are all in protection domain of the present utility model.
