Description
Technical Field
The utility model relates to a monitoring system, concretely relates to bus conductor contact failure's monitoring system for GIS.
Background
Compared with air insulation high-voltage electrical equipment, GIS equipment has the advantages of small occupied area, strong environmental adaptability, no maintenance and the like, and is widely applied to power grid construction at present. When faults such as interphase short circuit or relative ground short circuit occur in the GIS, after signals sent by the current transformer are received, the relay protection device acts to quickly cut off and isolate a fault line or bus.
However, when the bus conductor sliding contact, static contact and other parts are in poor electrical contact, and the bus conductor heats seriously and burns out under rated current, the background relay protection device does not act because the ground short circuit does not occur, and when the fault continues to deteriorate, and the burnt conductor metal liquid drops fall or splash to cause serious faults such as relative ground discharge or insulator flash, the relay protection device acts to trip to remove the fault. However, the discharge fault has already generated impact on the safe operation of the power grid, however, relevant disclosures for monitoring the contact condition of the bus conductor for the GIS are not given in the prior art.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art's shortcoming, provide a GIS is with generating line conductor contact failure monitoring system, this system can realize monitoring GIS is with generating line conductor's the contact condition.
In order to achieve the above object, GIS is with generating line conductor contact failure monitoring system include GIS generating line air chamber, control terminal, alarm device and host computer on the spot, wherein, be provided with a plurality of hand holes on the GIS generating line air chamber, hand hole department is provided with the generating line hand hole lid, wherein, the inboard of generating line hand hole lid is provided with temperature sensor, control terminal on the spot with temperature sensor is connected, control terminal on the spot's output and alarm device and host computer are connected.
The local control terminal is connected with the upper computer through a cable, an optical cable or a wireless communication mode.
The temperature sensor is a gas temperature sensor.
The utility model discloses following beneficial effect has:
GIS is with generating line conductor contact failure's monitoring system when concrete operation, based on can produce the phenomenon that generates heat unusually when GIS is with generating line contact failure, set up temperature sensor in GIS generating line air chamber, control terminal detects GIS generating line indoor temperature through temperature sensor on the spot, under the temperature abnormal conditions appearing, then report to the police through alarm device, send the data and the alarm signal that detect simultaneously to long-range host computer, monitor GIS with the generating line conductor contact condition in order to realize, and convenient operation, and is simple, and the practicality is extremely strong. In addition, the temperature sensor is arranged in a GIS bus air chamber, so that the influence of the external environment on the monitoring result is avoided.
