Technical field
The utility model transformer thermometer thermometer bulb protective device, belongs to the technical field that transformer thermometer thermometer bulb protects.
Background technology
Transformer thermometer is the operation oil temperature of measuring transformer and the critical elements of controlling cooling device and warning device, it is mainly made up of thermometer bulb, kapillary, flexible member, indicator gauge and microswitch, in the time that transformer temperature changes, temperature sensing medium expanded by heating (contraction) in thermometer bulb, the volume change producing passes on flexible member by kapillary and then produces a displacement, after amplifying, indicate dut temperature and drive microswitch work, control the input of refrigeratory or exit, guaranteeing that transformer can move with security and stability;
Conventionally thermometer bulb is arranged on the top cover of transformer, in order to measure better oil temperature, the fixed connection place of thermometer bulb and transformer should seal tight, when although thermometer dispatches from the factory with O-ring seal, but conventionally all do not reach in actual applications good seal request, rainwater easily invades in thermometer bulb mounting hole, pollute transformer oil, cause measuring inaccurate, affect the normal startup of refrigeratory, when transformer is stopped transport even in the winter time, icing and the freezing thermometer bulb of rainwater in thermometer bulb, temperature rise and then the thawing of freezing after transformer operation, transformer oil is oozed out from the junction of thermometer bulb and transformer, cause equipment failure,
Transformer is in the time of overhaul, seasonal maintenance or repairing, maintainer or other staff easily touch by mistake, step on by mistake thermometer bulb and the junction capillaceous of thermometer, because kapillary is too fragile, not protection, cause kapillary fracture, temperature sensing medium in thermometer bulb runs off, and causes thermometer misregister, has reduced the reliability of transformer-supplied.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is: provide one can effectively stop Leakage in Transformer oil, can avoid again kapillary by the transformer thermometer thermometer bulb protective device of artificial damage.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: transformer thermometer thermometer bulb protective device, comprise: thermometer thermometer bulb and kapillary, described thermometer thermometer bulb is arranged on the top cover of transformer, the bottom of described thermometer thermometer bulb is positioned at the inside of described transformer, the top of described thermometer thermometer bulb is positioned at the outside of described transformer and is connected with described kapillary, outer setting in the junction of described thermometer thermometer bulb and described transformer has wrappage, outer setting in described thermometer thermometer bulb and described junction capillaceous has protective cover.
Described protective cover is a sweeping pipe in upper end, be set in described outside capillaceous, the lower end of described protective cover is fixedly connected with base, and described base is fixed on by fixture on the top cover of transformer, described fixture is magnet, and described magnet is connected with described base by web member; Described web member is bolt, and described wrappage is mackintosh, and described protective cover and base are made by ferrous material, and described magnet is made up of ferrite permanent-magnet materials.
The utility model compared with prior art has following beneficial effect: the wrappage that 1, is arranged on the junction of thermometer thermometer bulb and transformer can prevent that rainwater from entering thermometer bulb mounting hole, effectively stops transformer to occur oil seepage phenomena; 2, the protective cover that is arranged on thermometer thermometer bulb and junction capillaceous has avoided kapillary by artificial destruction, has guaranteed the good contact of kapillary and thermometer bulb; 3, light, the volume minor benefit of the protective cover of bent-tube boiler is in installation, and fabulous to protective action capillaceous; 4, the fixed form of the combination of employing base and magnet is both convenient, fast, inexpensive, fixing reliable again, and easy operating; 5, mackintosh is cheap, has reduced making and maintenance cost as wrappage; 6, the protective cover that employing ferrous material is made not only weight is moderate, easily fixing, and intensity is large, protection effect is fabulous; 7, the magnet that adopts ferrite permanent-magnet materials to make, it is cheap, moderate performance, and can be processed into required form.
