Abstract
The utility model relates to a gas oil-level relay, which is a protection device protecting the safe operation of the oil immersion type full-sealed transformer. The utility model comprises an upper cover, a crust and a protective cover. A non conduction magnetic metallic pipe is arranged in the upper cover. A tripping operation reed switch and a signal reed switch are provided in the non conduction magnetic metallic pipe. A tripping operation float embedded with a tripping operation magnet and a signal float embedded with a signal magnet are sheathed out of the non conduction magnetic metallic pipe. A flag rod is connected with the tripping operation float as a whole. The tripping operation float and the signal float are floated upwardly and downwardly. The conditions of the gas quantity and the oil-level can be inspected through an inspection window. The movement range of the tripping operation float and the signal float are controlled by a position limiting element. The position limiting element is connected with the non conduction magnetic metallic pipe. The product has the functions of light gas alarming, oil level displaying, heavy gas tripping, etc. The utility model prevents the phenomenones generating such as fault-free alarming and tripping. The utility model has the features of compact structure, dependable performance and convenience installation.
Description
Technical field: the utility model relates to a kind of gas oil level relay, specifically a kind of protective device of oil immersed type full-sealed transformer security of operation.
Background technology: because the pasta of oil immersed type full-sealed transformer changes with ambient temperature and transformer temperature rise, report to the police and trip, cause transformer not send even so cause existing Buchholz relay fault-free to occur easily.
Summary of the invention: the purpose of this utility model is at above-mentioned prior art deficiency, and a kind of new gas oil level relay of multiple functional, dependable performance is provided.For achieving the above object, the utility model adopts following technical proposals: gas oil level relay, comprise loam cake (15), shell (5) and guard shield (1), and the top and the middle part of shell (5) are respectively equipped with inspection hole.Loam cake (15) outside is provided with binding post (14), vent plug (13) and stopper (12), and stopper (12) connects vent plug (13).Be provided with non-magnetic conductive metal pipe (16) in the loam cake (15), tripping operation reed switch (3) and signal reed switch (9) are housed in the non-magnetic conductive metal pipe (16), non-magnetic conductive metal pipe is inserted in tripping operation float (2) that is embedded with tripping operation magnet (4) and the signal float (11) that is embedded with signal magnet (10) outward, marker post (6) connects as one with tripping operation float (2), tripping operation float (2) fluctuates with signal float (11), can observe gas flow and oil level situation by inspection hole.Tripping operation float (2) is controlled by locating part (8) with signal float (11) range of movement.Locating part (8) is connected with non-magnetic conductive metal pipe (16).Glass tube (7) is connected with shell (5) by O-ring seal.
The utlity model has multiple functions such as light gas alarming, oil level demonstration, heavy gas tripping operation, prevented that fault-free from reporting to the police and the phenomenon of tripping operation takes place.Have compact conformation, dependable performance, characteristics easy for installation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, gas oil level relay, comprise loam cake 15, shell 5 and guard shield 1, the top and the middle part of shell 5 are respectively equipped with inspection hole, loam cake 15 outsides are provided with binding post 14, vent plug 13 and stopper 12, exhaust and collection failure gas usefulness in service when vent plug 13 supplies to install, stopper 12 connects vent plugs 13, and stopper 12 is used for oiling.Be provided with non-magnetic conductive metal pipe 16 in the loam cake 15, tripping operation reed switch 3 and signal reed switch 9 are housed in the non-magnetic conductive metal pipe 16, non-magnetic conductive metal pipe is inserted in tripping operation float 2 that is embedded with tripping operation magnet 4 and the signal float 11 that is embedded with signal magnet 10 outward, marker post 6 connects as one with tripping operation float 2, tripping operation float 2 fluctuates with signal float 11, can observe gas flow and oil level situation by inspection hole.Tripping operation float 2 is controlled by locating part 8 with signal float 11 range of movement.Locating part 8 is connected with non-magnetic conductive metal pipe 16.Glass tube 7 is connected with shell 5 by O-ring seal.
Operation principle: the utility model is made of the gas volume part of moving in signal signal float 11, signal magnet 10 and signal reed switch 9.Tripping operation float 2, tripping operation magnet 4 and tripping operation reed switch 3 constitute the minimum oil level part of moving in tripping operation.See through the form on the shell 5, can be at any time by watching marker post 6 to understand the situation of transformer pasta.Oil level just often shows green mark, then shows red marker during minimum oil level.Exhaust and collection failure gas in service were used when vent plug 13 supplied to install.Stopper 12 is used for oiling.Its inside is full of transformer oil when relay normally moves, and signal float and tripping operation float all are in high limit position, and two reed switch 3,9 contacts are the state of cut-offfing.When minor failure appears in transformer inside, transformer oil accumulates in the air chamber on relay top owing to decomposing the gas that produces, force its pasta to descend, signal float 11 descends thereupon, when reaching its signal magnet 10 adhesive signal reed switchs 9 when adjusting gas flow, alarm signal is sent in the connection signal loop.When transformer inner generation catastrophe failure or fuel tank leakage of oil, tripping operation float 2 descends thereupon.When reaching its tripping operation magnet 4 adhesives tripping operation reed switch 3 when adjusting minimum pasta, connect trip(ping) circuit and cut off transformer frequency response.
