Description
Technical field
The present invention relates to transformer Buchholz relay control field, especially a kind of transformer Buchholz relay with wireless remote means of deflation.
Background technology
Main transformer, in operational process, not exclusively can produce gas because sealing is bad or oil product is degassed, and particularly, when breaking down, in main transformer, oil product may thermal cracking occur and produce a large amount of gas.Above gas all can be gathered on Buchholz relay, and as emission gases not in time, these gases can produce electric discharge phenomena under high-voltage electric field effect, will seriously jeopardize main transformer safe operation.Main transformer maintenance, the replacing of respirator silica gel, repairing, oil strain, hot oiling and other work that may produce free gas complete and power transmission after 4 hours carrying out, and all must on Buchholz relay, exit, to guarantee main transformer safe operation.Present widely used traditional main transformer Buchholz relay is divided into: two kinds of forms of drawing lower air-guide box and being unkitted air-guide box are housed, and the Buchholz relay of all main transformer on-load switchs and part main transformer Buchholz relay are not equipped with and draw lower air-guide box.To the Buchholz relay that draws lower air-guide box is housed, when Buchholz relay need to be exitted work, the air release that must open air-guide box to transforming plant main transformer scene by staff is exitted to Buchholz relay; To the Buchholz relay that does not have dress to draw lower air-guide box, must climb up charged main transformer by staff Buchholz relay is exitted, be absolutely unsafe.No matter there is dress or be unkitted the main transformer Buchholz relay that draws lower air-guide box, when its inner gathering gas, all must staff to main transformer scene, Buchholz relay be exitted, particularly when the inclement weathers such as thunderstorm, sleet, typhoon, surrounding is covered with the other work of main transformer of high voltage equipment, has very large danger.While carrying out main transformer Buchholz relay venting work to unattended operation transformer station, all need to send specially several professionals to take 2 cars separately to work on the spot, work consuming consuming time, causes the waste of great material, the energy, cost of labor etc. at every turn.
Summary of the invention
In view of this, the object of this invention is to provide a kind of transformer Buchholz relay with wireless remote means of deflation, in transformer station's master-control room of Attended mode, (or in other pulpit) just can be to unmanned or other Attended mode transforming plant main transformer Buchholz relays carry out Remote venting everywhere in realization.
The present invention adopts following scheme to realize: a kind of transformer Buchholz relay with wireless remote means of deflation, it is characterized in that: comprise a Buchholz relay, described Buchholz relay connects a pressure-releasing electromagnetic valve, described pressure-releasing electromagnetic valve connects a wireless receiving module, described Buchholz relay is connected with conservator by a butterfly valve, and described Buchholz relay is also connected with main transformer body by a connecting pipe; Also comprise that remote controllers are arranged in transformer station's master-control room or in other pulpit, described remote controllers comprise a processor and a wireless transmitter module, in order to carry out communication with described wireless receiving module.
In an embodiment of the present invention, described remote controllers also comprise display module and the button being connected with described processor, and described button comprises that a startup button and stops key.
In an embodiment of the present invention, described wireless transmitter module and described wireless receiving module are Zigbee module or GPS wireless module.
In an embodiment of the present invention, described Buchholz relay is connected by a bleeder pipe with described pressure-releasing electromagnetic valve.
In an embodiment of the present invention, between described bleeder pipe and described pressure-releasing electromagnetic valve, by a bleeder pipe joint, be connected.
The present invention is with the transformer Buchholz relay of wireless remote means of deflation; on main transformer Buchholz relay, assemble gas; light watt of protective relay of main transformer can send alerting signal; now only need operation to be arranged on the remote controllers of (or in other pulpit) in transformer station's master-control room; just can carry out long-range venting to main transformer Buchholz relay; without staff, to transforming plant main transformer scene, Buchholz relay is exitted, more without the main transformer of climbing up charging operation, exit.It is central because of widely used traditional main transformer Buchholz relay that the present invention has overcome prior art, when its inner gathering gas, the transforming plant main transformer that must be covered with high voltage equipment to surrounding by staff is on-the-spot, and the main transformer that sometimes even also will climb up charging operation carries out venting work to Buchholz relay; Especially at bad or inclement weathers such as blowing and rainings, in being full of the open-air atmosphere of high voltage equipment, surrounding works, have more danger.
For making object of the present invention, technical scheme and advantage clearer, below will, by specific embodiment and relevant drawings, the present invention be described in further detail.
