The main transformation respirator comprises a main transformation body and an expansion tank connected with the upper portion of the main transformation body, the expansion tank is connected with a main transformation respiration tube, the main transformation respiration tube is in parallel connection with two drying tanks including a tank A and a tank B, one branch tube of the main transformation respiration tube is provided with a valve A and is connected with the tank A, and the other branch tube of the main transformation respiration tube is provided with a valve B and is connected with the tank B. According to the device and the method, moisture absorbents do not need to be replaced, the problems that when moisture absorbents of a traditional main transformation respirator need to be replaced, a heavy gas protection mode needs to be switched off and safety hidden risks exist are solved, the defect that the device is under moisture attack due to the fact that the main transformation respiration tube is directly communicated with external atmosphere after a silica gel tank is disassembled and accordingly external moisture is directly sucked in through main transformation respiration air currents is overcome, safe operation of the main transformation respirator is guaranteed well, and labor and material waste and environment pollution are avoided in the moisture absorbent replacement process.
Description
Technical field
The present invention relates to main transformer, particularly a kind of main transformer respirator and using method with photovoltaic conversion on-line regeneration function.
Background technology
Main transformer is in operation, and can produce respiration by respiratory siphon and outside air, as nothing on respiratory siphon, respirator is installed, and main transformer directly sucks extraneous humid air, more easily makes main transformer make moist especially in rainy day and high humidity weather.In tradition main transformer respirator, discolour silica gel hygroscopic agent is housed; in the time that its hygroscopic agent discolour silica gel moisture absorption is saturated; the silica gel tank that needs staff to carry qualified dry hygroscopic agent or to install qualified hygroscopic agent is changed to main transformer scene; in Renewal process, main transformer respiratory siphon directly communicates with ambient atmosphere; can cause that main transformer respiratory air flow changes; may cause the catastrophe failure of the heavy watt malfunction of main transformer Buchholz relay; therefore traditional main transformer respirator just can carry out after a heavy main transformer watt protective device must being exited in the time changing adsorbent, reaches 4-5 hour disengaging time.
A heavy watt protection is that main transformer moves one of most important protective device; when main transformer is in the time that the fault of oil stream or gas shock occurs to produce contingency; Buchholz relay weight watt can move; make main transformer switch tripping operation; the further expansion of Accident prevention,, can not cut off main transformer switch by now heavy watt as exit; cause fault spread, even cause the serious consequence of main transformer blast.Moving back heavy watt protective device need be after the chief engineer of unit one belongs to approval, is operated work consuming, consuming time and expend a lot of by operations staff's transformer station's master-control room of making a special trip to a certain place.
Another shortcoming of tradition main transformer respirator is, in the time changing discolour silica gel, to unload after silica gel tank, main transformer respiratory air flow directly communicates with ambient atmosphere, make moisture, moisture easily breathe connecting leg by main transformer and invade in main transformer oil, and change hygroscopic agent and can cause waste, the while is easy contaminated environment also.
Summary of the invention
The problem that the present invention is directed to above-mentioned prior art existence is made improvement, be that technical problem to be solved by this invention is to provide a kind of main transformer respirator and using method thereof with photovoltaic conversion on-line regeneration function, this device and method is without changing hygroscopic agent, having solved traditional main transformer respirator need to exit heavy watt when hygroscopic agent and protect and have problems such as potential safety hazard in the time changing, having overcome main transformer respiratory siphon while unloading silica gel tank directly communicates and makes main transformer respiratory air flow that direct suction of extraneous moisture moisture caused to the defect of making moist with ambient atmosphere, thereby powerful guarantee main transformer safe operation, also avoided manpower in replacing hygroscopic agent process simultaneously, the waste of material resources and environmental pollution.
