Insulation and arc extinction performance when making.The evaluation amount of air chamber state includes：Rated operating pressure, minimum operating pressure, safe release
Run time, year leakage rate, gas humidity is allowed to allow content, wherein sealing system service life, gas after pressure, pressure release
Chamber pressure force parameter is most important.
Although the sealing requirements of air chamber are high, manufacturing process is strict, and dispatching from the factory has air tight test.But due to ageing equipment,
The presence of artificial and environmental factor, after putting equipment in service, various degrees of leakage problem often occurs in air chamber.Once leak
Gas, the insulation of switch cubicle and arc extinction performance will decline, so as to influence equipment operation safety.Therefore, comprehensive reliable air chamber pressure
The safe operation that power is monitored for equipment is of crucial importance.
At present, most 33KV GIS air chamber of switch cabinet pressure are monitored using mechanical meter, are connect in place by pointer
Logical mode is fed back.This mode, it is most clearly disadvantageous to be：Air chamber pressure value can not be monitored in real time, can not reflect and
Evaluate the insulation of switch cubicle and the good and bad degree of arc extinction performance.
Utility model content
Technical problem to be solved in the utility model, is just to provide a kind of gas insulation switch cabinet air chamber pressure state and exists
Line monitoring device, it can monitor air chamber pressure value in real time, while measured value is sent into backstage, the rate of change of monitoring pressure in real time
And variation tendency, alarming threshold value is set, and triggering on-line monitoring system action, prompting maintenance personnel take measures.
Above-mentioned technical problem is solved, the technical scheme that the utility model is used is as follows：
A kind of gas insulation switch cabinet air chamber pressure state on_line monitoring device, described air chamber has several, described
Monitoring device it is characterized in that：Including serial server, interchanger, monitoring host computer, state estimation host computer and some pressure
Sensor；The pressure sensor is provided with mailing address encoder, and is separately fixed in each air chamber, the serial server
It is connected respectively with pressure sensor each described, the interchanger is simultaneously upper with the monitoring host computer and the state estimation
Machine is connected, and the serial server is connected with the interchanger；The pressure sensor transfers signals to the serial port service
Device, the serial server transfers signals to the interchanger again, and the interchanger will be respectively transmitted to institute after Modulation recognition
State monitoring host computer and the state estimation host computer.
Further, the pressure sensor is additionally provided with 485 COM1s, and passes through 485 lines and the serial server
Connection.
Further, the serial server is connected by netting twine with the interchanger, and the interchanger passes through netting twine
It is connected simultaneously with the monitoring host computer and the state estimation host computer.
Beneficial effect：
The utility model installs pressure sensor in each air chamber, in real time the pressure value in record air chamber, by coherent signal
Connected by 485 line simultaneous transmissions to serial server, serial server is then transmitted the signal of pressure sensor by netting twine
Taken measures in advance to monitoring host computer, state estimation host computer, and by outside control, failure is reduced to minimum.Supervise simultaneously
Control host computer and state estimation host computer are stored, recorded and analyzed gas pressure change trend and change to gas pressure value
Rate sets alarming threshold value, triggering monitoring system action, prompting maintenance people there is provided state assessment analysis image according to variation tendency
Member takes measures.
Therefore, the utility model attachment structure is simple, and air chamber pressure value can be monitored in real time, is set and alarmed according to variation tendency
Threshold values, triggering monitoring system is taken measures, and failure is reduced into minimum.
