Electrical equipment breaks down.Switchgear water inlet be easy to cause equipment in cabinet to corrode, and causes insulation ag(e)ing to be accelerated, leads to electrical equipment
It damages or burns and cause fire, or the generation of the accidents such as power failure suddenly.
It is mostly to carry out Prior Control, Wu Fa using covering water-tight device outside cabinet that existing switchgear, which prevents the measure into water,
Switchgear timely finds and handles when intaking；If water detection device is set in switchgear come judge in switchgear whether
Water inlet, since water detection device is normally based on the testing principles such as optics, can consume a large amount of energy in the course of work, and be
Effective detection ponding situation needs for a long time to open water detection device, this is easy for causing energy waste, while increasing device
The loss of part increases cost.
Summary of the invention
The object of the present invention is to provide a kind of water detection method and devices of switchgear, to solve existing ponding inspection
Survey device energy-wasting higher the problem of be easy to causeing damage.
To achieve the above object, the present invention provides a kind of water detection methods of switchgear, comprising the following steps:
The humidity value in the switchgear is detected, judges whether the humidity value reaches setting value；
Optical water-level detection device is opened if the humidity value reaches the setting value；
Ponding height value in the switchgear is detected, issues alarm if the ponding height value reaches setting height value
Signal.
Further, remote terminal is sent for the humidity value and the ponding height value by wireless network.
Further, the humidity value and the ponding height value are shown on a display screen.
The present invention also provides a kind of water detection device of switchgear, including controller and memory, the controllers
It is connected with humidity sensor, optical water-level detection device and warning device, the memory is stored with the controller and realizes such as
The instruction of lower method:
The humidity value in the switchgear is detected, judges whether the humidity value reaches setting value；
Optical water-level detection device is opened if the humidity value reaches the setting value；
Ponding height value in the switchgear is detected, issues alarm if the ponding height value reaches setting height value
Signal.
Further, remote terminal is sent for the humidity value and the ponding height value by wireless network.
Further, the humidity value and the ponding height value are shown on a display screen.
Beneficial effects of the present invention: by first being detected to the humidity in switchgear, when humidity value is more than setting value
Water detection device is just opened, ponding situation in switchgear is detected.The present invention can close ponding in normal work
Detection device only judges ponding situation by detecting humidity, just considers to open water detection device when humidity is excessive, so not
The energy consumption of water detection device is only reduced, and since water detection device is not on normally open, reduces device damage
Consumption, increases service life.
Detailed description of the invention
Fig. 1 is flow diagram of the invention；
Fig. 2 is system structure diagram of the invention；
Fig. 3 is the circuit diagram of power supply in present system.
Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawing.
The present invention provides a kind of water detection method and devices of switchgear, are used for effective detection switch cabinet ponding feelings
The problem of condition, solving device energy consumption is higher, and device is easily damaged.In reality, when occurring ponding situation in switchgear, environment
In humidity value it is generally all very high, and the ponding in cabinet body might not be many at this time, especially south or seashore etc.
Area, the humidity in air is generally all bigger, especially encounters rainy weather, is usually all that air humidity becomes larger, and cabinet body
In not necessarily have many ponding.In view of existing water accumulation level detection device (such as based on optical water level detecting) is tied
Structure is complex, and device is various, if water detection device is chronically at open state, not only consumes a large amount of energy, simultaneously
Also the loss for increasing device, increases cost.
It is as shown in Figure 1 flow chart of the invention, the humidity in switchgear is detected first, water detection fills at this time
It sets and does not open.When detecting that humidity is greater than the set value in switchgear, illustrate that atmospheric water content is excessively high, at this time in switchgear
It is possible that there is ponding situation, therefore water detection device is opened, the ponding in switchgear is detected.If detected out
It closes in cabinet and ponding occurs, and the water level of ponding has been more than specified altitude, then issue alarm signal, remind staff's maintenance.
Alarm signal can also be issued in the above process when detecting that humidity value is greater than the set value, staff is reminded to pay attention to.Simultaneously
Every testing result and warning message are sent to remote terminal by communication network, are shown on a display screen.
As shown in Fig. 2, a kind of water detection device of switchgear provided by the invention, comprising: power module, water detection
Unit, humidity detection unit, central processing unit, alarm unit, display device and wireless communication module.The Humidity Detection list
The usable humidity sensor of member, for the humidity in real-time detection cabinet, and the humidity data that will test be sent in real time it is described
Central processing unit；The water detection unit, which can be used, is based on optical water-level detecting device, whether there is for detecting box bottom
Ponding, and the ponding state that will test is sent to the central processing unit；The central processing unit is for receiving the ponding
Data Concurrent transmitted by detection unit and humidity detection unit gives wireless communication module.
The cabinet humidity value of received humidity value and standard is carried out real time contrast by central processing unit, if receive
Humidity value is greater than the cabinet humidity value of standard, and the central processing unit issues police instruction to the alarm unit；It is then turned on
Water detection unit, detects water accumulation level, if detecting that water accumulation level is greater than the set value, issues to alarm unit
Alarm command.The alarm unit includes warning device 1 and warning device 2；The warning device 1 is for receiving the centre
It manages the ponding exceptional instructions that device is sent and issues alarm sound；The warning device 2 is for receiving the central processing unit hair
The cabinet humidity exceptional instructions sent simultaneously issue alarm；The display module is used for the cabinet humidity value of real-time reception in liquid
Brilliant screen display comes out；The wireless communication module is used for the ponding state and cabinet that central processing unit described in real-time reception is sent
Interior humidity value is simultaneously sent to monitoring backstage.
In the present invention, the central processing unit is connected with power module, as shown in figure 3, the power module can be direct
Auxiliary bus-bar joint row's connection with switchgear is powered.The model of the central processing unit is STC12C5A60S2, at low cost
It is honest and clean, it is powerful.The wireless communication module is GPRS module, while being connected with SIM interface device, will receive data in real time
It is sent to monitoring backstage.
In conclusion the present invention realizes switchgear product by being used cooperatively for humidity detection unit and water detection unit
Water and alarm, and with monitoring backstage interact, guarantee staff switchgear ponding situation is grasped in time, realize pair
Switchgear safe operation is supported.
Specific embodiment of the present invention is presented above, but the present invention is not limited to described embodiment,
Such as the change to processor, humidity sensor or communication modes, the technical solution formed in this way be to above-described embodiment into
Row fine tuning is formed, and this technical solution is still fallen in protection scope of the present invention.
