Abstract
The utility model relates to a metal corrugated conservator for a transformer. The metal corrugated conservator for the transformer comprises a fully-sealed oil chamber of the oil conservator, wherein the fully-sealed oil chamber is composed of an oil conservator shell body and a metal corrugated pipe. A gas relay which is communicated with the oil chamber is arranged on the top of the oil conservator, an oil level gage which has the remote transmission function is arranged on the end portion of the metal corrugated pipe, and the gas relay and a signal line of the oil level gage are connected to an external control circuit. The metal corrugated oil conservator for the transformer is provided with the oil conservator outer shell and the metal corrugated pipe arranged in side the oil conservator, has the leakage warning function and the high-low oil level warning function, can ensure safe operation of the transformer, and lays a hardware basis for realization of automatic intelligent control.
Description
Technical field
The utility model relates to a kind of Transformer Manufacturing Technology, specifically a kind of metal bellow type oil conservator for transformer.
Background technology
Metal bellow type oil conservator for transformer is the conventional products that generally is applied in the power transmission and transformation system, the pressure test that regulation oil conservator cabinet should be able to bear 50kPa in the national sector standard " JB/T6484-2005 ", and lasting 30min answers ne-leakage; Core body of coil-storage cabinet should be able to bear the leakage test that vacuum degree is not more than 50Pa, continues 30min, seepage must not be arranged and permanent deformation occurs.Oil conservator on the market can both be accomplished the requirement to sealing in the standard when delivery test now.But after oil conservator was contained on the transformer operation, the ftracture accident of leakage of oil of the aging leakage of oil of oil conservator sealing gasket and metal bellows can appear in once long along with running time, brings major safety risks to electric power netting safe running.
Yet, along with the development of power transmission and transformation industry, the useful life of transformer oil storage, the reasonable disposition of oil conservator are had higher requirement, increasing oil conservator shell seepage and interior metal bellows monitoring of leakage warning function is the problem that needs solution.
The metal bellow type oil conservator for transformer that at present, can satisfy above-mentioned requirements there is not yet report.
The utility model content
Sealing problem for transformer oil storage in the prior art easily brings this weak point of major safety risks to electric power netting safe running, and the technical problems to be solved in the utility model provides a kind of metal bellow type oil conservator for transformer that can guarantee the safe operation of transformer.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The utility model metal bellow type oil conservator for transformer has the hermetically sealed oil conservator grease chamber that is made of oil conservator housing and metal bellows, is provided with the Buchholz relay that is connected with the grease chamber at the oil conservator top; The end of metal bellows is provided with the oil level gauge with transporting function; The holding wire of Buchholz relay and oil level gauge is connected to external control circuit.
Described Buchholz relay replaces with the tubular type oil level gauge.
Described oil level gauge is pointer-type, and table bar one end of this oil level gauge is connected with metal bellows, and the other end is connected to the pointer of oil level gauge.
The utlity model has following beneficial effect and advantage:
1. the utlity model has oil conservator shell and oil conservator interior metal bellows leakage alarm function, height warning function, indication realizes the metal corrugated oil conservater of 4～20mA distant place transfer function to oil level.
2. the accuracy that shows of longer service life of the present utility model, more reasonable, the oil level of configuration is higher, the distant place transmission meeting of oil level signal gathers and stores oil level signal more easily, oil conservator shell and oil conservator interior metal bellows leakage alarm function more can guarantee the safe operation of transformer, have established hardware foundation for realizing automatic intelligent control.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the right view of Fig. 1.
Wherein, 1 is the oil conservator housing, and 2 is metal bellows, and 3 is Buchholz relay, and 4 is cover plate for manhole, and 5 is pointer oil level gauge, and 6 is respiratory siphon, and 7 is pipe joint, and 8 is valve, and 9 is the cabinet pin.
Embodiment
The present invention is further elaborated below in conjunction with Figure of description.
As shown in Figure 1, the utility model metal bellow type oil conservator for transformer has the hermetically sealed oil conservator grease chamber that is made of oil conservator housing 1 and metal bellows 2, is provided with the Buchholz relay that is connected with the grease chamber at the oil conservator top; The end of metal bellows 2 is provided with the oil level gauge with transporting function, and the holding wire of Buchholz relay and oil level gauge is connected to external control circuit.
Described Buchholz relay 3 can substitute with the tubular type oil level gauge, and its holding wire is connected to external control circuit, all can realize the function of leaking hunting.Adopt Buchholz relay 3 in the present embodiment, when oil conservator housing 1 or oil conservator interior metal bellows 2 generation seepage, gas will enter the oil conservator grease chamber and accumulate in the Buchholz relay 3, when the gas that gathers reaches set point, the action of Buchholz relay 3 contacts is sent alarm signal by holding wire to external control circuit simultaneously.
Oil level gauge adopts pointer oil level gauge 5, possesses 4～20mA transporting function, is installed on the end of metal bellows 2, is used for observing oil level.The table bar of pointer-type oil level gauge 5 is connected with metal bellows 2, and metal bellows 2 drives the table bar of pointer oil level gauge 5 in the process that stretches or compress a end swings, and the other end of table bar drives the beat of pointer of pointer oil level gauge 5 again and shows oil level.Simultaneously, the swing of indicator drives the rotation of indicator axle upper sensor and exports 4～20mA remote transfer signal and deliver to external control circuit.
The utility model is provided with cover plate for manhole 4 in the end of metal bellows 2, and the respiratory siphon 6 that communicates with metal bellows 2 is arranged on this cover plate for manhole 4; Be provided with for the pipe joint 7 of annotating, draining the oil in the bottom of oil conservator, be used for the valve 8(that is connected with the transformer oil circuit as shown in Figure 2) to be used for transformer the cabinet pin 9 of locating is installed.
