With reference to shown in Fig. 1 and Fig. 2, according to embodiment of the present utility model, there is provided a kind of device for protection of terminal.
Specifically, the device for protection of terminal includes the damp device 20 of housing 10, drop, detection means 30 and controller 40.Drop Damp device 20 is arranged in housing 10.Detection means 30 is used to detect 10 internal medium signal of housing.Controller 40 is used to receive Ambient signal, controller 40 is according to the damp device 20 of ambient signal control drop is in running order or stopped status.
In the present embodiment, the work of the damp device 20 of drop is controlled using controller by the ambient signal in housing 10 State, realizes the remotely control of device for protection of terminal so that operating personnel is can be achieved with to terminal protecting by controller 40 Device carries out dehumidifying drop tide, significantly reduces the working strength of operating personnel, improves the work efficiency of operating personnel.
Wherein, dropping damp device 20 includes heater 21, is arranged in housing 10.Housing of effectively can going out so is set Dampness inside 10.Play a part of to protect terminal and be arranged at the other elements of enclosure interior.
In order to further increase the drop tide effect of the damp device 20 of drop, heater 21 includes being arranged on 10 side wall of housing Heating plate.
Preferably, heater 21 is multiple, and multiple heaters 21 are oppositely disposed on the side wall of housing 10.In order to effective The dampness of enclosure interior is discharged totally by ground, and heater 21 is disposed in proximity on the side wall on 10 bottom of housing.
The damp device 20 of drop includes fan 22 and temperature controller 31 and humidity controller 32.Fan 22 is for multiple, multiple Fan 22 is arranged in housing 10.Temperature controller 31 is used to detect the temperature in housing 10, i.e. ambient signal in housing 10 Including temperature signal and moisture signal in housing 10.Fan 22 is controlled by controller 40 to start, will be wet in housing 10 Air-blowing goes out, and increased the drop tide efficiency of the damp device 20 of drop.By 32 monitor in real time housing of temperature controller 31 and humidity controller Temperature and humidity situation in 10, can be discharged in time to the dampness inside housing 10, it is ensured that locate in housing 10 all the time In the environment of terminal trouble free service, the service life and reliability of terminal and other components and parts is increased.
In order to further cause operating personnel to be timely purged to the dampness inside housing 10, the terminal protecting is filled Put and be also provided with alarm set.Alarm set is electrically connected with detection means 30, and when ambient signal reaches preset value, alarm set is sent out Go out alerting signal, operating personnel sees or hear alerting signal, housing 10 will be carried out except wet trade.Wherein, remind letter Number can be alarm device, or be positioned close to the alarm lamp of controller or work operations room.
In order to effectively discharge the dampness inside housing 10 outside housing 10 in time, air vent has been opened up on the housing 10. Exhaust ports are provided with for opening or closing the baffle plate 50 of air vent.When the damp device 20 of drop works, baffle plate 50 automatically will row QI KOU is opened, and when the damp device 20 of drop quits work, air vent is sealed by baffle plate 50 automatically.Wherein, fan 22 and aerofluxuss Mouth is oppositely arranged.So in time the dampness in housing 10 can be discharged outside housing 10.
Device for protection of terminal in the present embodiment, the outdoor terminal box of transformer substation with temperature and humidity intelligent control function, it Itself there is the damp warning function of cold-proof drive, automatic alarm can automatically adjust when low temperature, moisture are overweight, and can be convenient in master control room The humiture checked inside each outdoor terminal box, and damp function can be driven by the manually opened heating in a controller distant place.
The down either side installing heating plate inside the terminal box, by the connection of heating power supply can inside the terminal box i.e. shell Steam convection current is produced inside body 10, dampness flowing is ordered about.
Meanwhile, install fan additional and reserve steam vent.Fan is located at the position on steam vent opposite, and above casing, lower section respectively sets one It is individual, by the electric power starting for connecting fan, drive tide cooling.Air vent is located at terminal upper box part, and baffle plate setting is mechanical latching, when When heating plate or fan power supply start, mechanical latching is released, and baffle plate just can be with activity, it is ensured that be still in most of time casing Closed.
Epidemic disaster intelligent controller is installed additional in outdoor terminal box, and carries automatic alarm and transporting function, terminal box interior temperature Moisture signal can be uploaded in real time, when temperature or humidity transfinite, device automatic alarm, and automatic heating or fan dress Put.
As shown in Fig. 2 have relay 1,2 on temperature and humidity controller, and when the temperature is too low, 1 closing of contact of relay, plus Hot device starts.When humidity is excessive, relay 1,2 closings of contact, heater, fan start.A in Fig. 2 is fault alarm, 3 is total power switch.Temperature and humidity controller is connected to master control room i.e. controller backstage by data/address bus, and operation maintenance personnel can be remote Each terminal box signal is checked by side, it is also possible to which remote manual control opens or closes the heating of terminal box or fan power supply.
In the present embodiment, effectively improve the cold-proof drive tide problem of existing outdoor terminal box.Using the intelligence in the present embodiment Can terminal box, can monitor on-line, scene automatically and remote control adjusts the temperature and humidity of box house, O&M can be reduced The workload of personnel and make an inspection tour number of times, compared to existing technology in terminal box, the probability for breaking down is relatively low, the letter of this structure design It is single, it is easy to produce.
Preferred embodiment of the present utility model is the foregoing is only, this utility model is not limited to, for this For the technical staff in field, this utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle Within, any modification, equivalent substitution and improvements made etc. are should be included within protection domain of the present utility model.
