Abstract
The utility model relates to a humidity indicating-warning system aiming at a silica gel respirator. The humidity indicating-warning system comprises the silica gel respirator, a humidity sensor, a converter, a monitoring module and a warning module, wherein the humidity sensor is inserted into the upper part of the silica gel respirator and is used for transmitting collected humidity signals to the monitoring module in a monitoring chamber through the converter, the monitoring module displays a humidity value in real time, and the warning module is started by virtue of the humidity signals to realize a warning function when the humidity is higher than a preset critical value. According to the humidity indicating-warning system, the silica gel respirator of a main transformer of a transformer substation is intelligently designed, the situations of silica gel ageing, air drying capacity and the like of the silica gel respirator are monitored in real time by virtue of a sensor technique and a remote warning technique, the increase of air humidity in equipment is timely found, and the silica gel is exchanged, so that the normal and reliable operation of the equipment is guaranteed.
Description
Technical field
The utility model belongs to field transformer, relates to the respirator of transformer, especially for the humidity indication warning system of silica gel respirator.
Background technology
Big-and-middle-sized transformer in electrical network generally all has respirator, this respirator is a glass container, inside contain into hygroscopic agents such as discolour silica gels, establish the lubricating cup of a Sheng transformer oil in its lower end, in cup, fill transformer oil, enter the air of main transformer first by transformer oil elimination dust, then by silica gel elimination moisture content wherein, the last like this air that enters into main transformer inside is just relatively dried pure, can play the aging problem of insulating oil in transformer that prevents.
Discolour silica gel is being blue look before moisture absorption, pack into bright in colour after respirator, be convenient to observe, just become white in state of saturation if discolour silica gel sucks enough moisture content.Operator on duty can be by the variation of silica gel color in respirator, judges whether deliquescence of silica gel, when deliquescence part accounts for 2/3rds when above of entirety, just should change.
Some transformers are located among the lowland of remote mountains, and the temperature difference is large, high humidity, and staff is likely difficult to the problem of finding that in time silica gel wettability power declines.Because respirator has lost the buffer action of transformer oil and humid air, switch is inner directly to communicate with atmosphere for a long time, malaria directly enters in oil conservater for a long time, vary with temperature formation condensation, condensation accumulated water enters loaded switch body interior, transformer oil water cut is increased, oil quality deterioration, dielectric strength declines, and causes the problems such as transformer major insulation is abnormal.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of humidity indication warning system for silica gel respirator that realizes energy-conserving and environment-protective, automatic control, telemonitoring effect is provided.
The technical scheme that the utility model technical solution problem adopts is:
A kind of humidity indication warning system for silica gel respirator, formed by silica gel respirator, humidity sensor, converter, monitoring module and alarm module, humidity sensor is inserted on top at silica gel respirator, this humidity sensor is transferred to the monitoring module in Control Room by the moisture signal collecting by converter, monitoring module shows humidity value in real time, when humidity higher than set critical value time, this moisture signal starts alarm module and realizes warning function.
And the circuit of described alarm module is latching circuit.
Advantage of the present utility model and good effect are:
1, this warning system is carried out intelligent design to the silica gel respirator of main transformer of transformer substation, utilize sensor technology and remote alarms technology, the situations such as, air drying capacity aging to the silica gel in silica gel respirator are monitored in real time, in discovering device, air humidity increases in time, change silica gel, to ensure the normal reliable operation of equipment.
2, this warning system is inserted humidity sensor on the top of original silica gel respirator, sensor signal is transferred to the monitoring module in Control Room by converter, monitoring module shows humidity value in real time, when humidity is during higher than critical value, this moisture signal can be used as control signal, starts in time alarm lamp, reminds in time staff to change silica gel, to reduce accident rate, reduce equipment property loss.
Brief description of the drawings
Fig. 1 is circuit control schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
For a humidity indication warning system for silica gel respirator, formed by silica gel respirator, humidity sensor, converter, monitoring module and alarm module.Humidity sensor is inserted on top at silica gel respirator, this humidity sensor is transferred to the monitoring module in Control Room by the moisture signal collecting by converter, converter converts electrical signals to numerical value and shows, monitoring module shows humidity value in real time, when humidity higher than set critical value time, this moisture signal starts alarm module and realizes warning function, reminds staff to change silica gel.
The circuit of described alarm module is latching circuit, when detecting the air humidity in respirator, humidity sensor exceedes setting value, while being the dehumidifying effect decline of silica gel in respirator, humidity gauge tap closure, relay K M obtains electric, normal open switch KM2 closure, the right electric loop forms loop, it is bright that alarm lamp obtains lighting, left side control loop is due to KM1 closure, form latching circuit, make whole alarm module after starting, can not be subject to again the impact of humidity gauge tap, ensured before staff checks respirator, alarm lamp is always in obtaining electricity condition.After staff changes silica gel again, press normally closed button SF, control loop is opened circuit, relay K M dead electricity, K switch M2 disconnects, and K switch M1 disconnects, and alarm lamp extinguishes.
Alarm module adopts latching circuit, once make the action of humidity gauge tap, just can make whole module automatically keep continuing energising, makes it to open circuit until press normally closed switch SF.
The principle of work of this warning system:
This warning system is carried out intelligent design to the silica gel respirator of main transformer of transformer substation, utilize sensor technology and remote alarms technology, the situations such as, air drying capacity aging to the silica gel in silica gel respirator are monitored in real time, in the time finding that silica dehydrator ability declines, start in time alarm lamp, remind in time staff to change silica gel, ensure the normal reliable operation of equipment.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of utility model design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
