Description
Technical Field
The utility model relates to a device for monitoring damage of a capsule of a transformer oil conservator, and belongs to the technical field of transformers.
Background
At present, the method for monitoring the damage of the capsule of the existing transformer oil conservator is to place a probe with a light source in the capsule of the oil conservator, because the refractive indexes of light in different media are different, whether the refractive index of the light monitored by the probe is changed or not is judged to monitor whether oil exists in the capsule or not. The prior art has the following problems: firstly, the light source is limited, and the light source cannot be monitored when damaged; secondly, if the capsule is wrapped by the probe after being damaged, the state of the capsule cannot be accurately fed back.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a device for monitoring the damage of a transformer oil conservator capsule, which is not limited by environmental conditions, can accurately monitor whether the transformer capsule of the transformer oil conservator is damaged or not, ensures the safe operation of a transformer and solves the technical problems in the prior art.
The utility model adopts the following technical scheme:
a monitoring device for damage of a capsule of a transformer oil conservator comprises the transformer oil conservator, the capsule, transformer oil, an oil conservator opening, a connecting pipe, a float switch, an air release plug and an alarm, wherein the capsule is arranged in the transformer oil conservator and is filled with the transformer oil; the connecting pipe of the float switch is provided with an air relief plug; and after the transformer oil conservator is vacuumized, transformer oil is injected, and gas in the transformer oil conservator is discharged through a gas release plug at the position of the float switch. Therefore, the transformer oil storage cabinet and the interior of the float switch are filled with transformer oil, and the capsule is in an expansion state; if the capsule is broken and contracted, the oil level of the transformer oil storage cabinet is lowered, the float switch is switched on, and the alarm sends out an alarm signal, so that the purpose of monitoring whether the capsule of the transformer oil storage cabinet is damaged or not is achieved.
The transformer stores up oil tank top and is equipped with oil storage cabinet mouth, and the capsule passes through oil storage cabinet mouth to be installed in the transformer stores up oil tank, and the capsule passes through oil storage cabinet mouth and external intercommunication.
The working principle is as follows: the float switch is arranged at the high point of the transformer oil conservator, when the transformer normally runs, the outer side of a capsule in the transformer oil conservator is filled with transformer oil, the inner side of the capsule is communicated with the outside and is filled with dry air, and at the moment, the float switch cannot send out an alarm signal; when the capsule is damaged (such as cracking or crevasse) due to some reason, air inside the capsule can enter the transformer oil storage cabinet, the pressure difference between the inside and the outside of the capsule disappears, the capsule shrinks, the oil level drops, the float switch is switched on, and the alarm can send out an alarm signal.
The utility model has the beneficial effects that: the transformer capsule monitoring device is not limited by environmental conditions, whether the transformer capsule of the transformer oil conservator is damaged or not can be accurately monitored, and safe operation of the transformer is guaranteed.
Drawings
FIG. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure: the transformer oil storage tank comprises a transformer oil storage tank 1, a capsule 2, transformer oil 3, an oil storage tank opening 4, a connecting pipe 5, a float switch 6, an air release plug 7 and a capsule damaged part 8.
Detailed Description
The utility model is further described with reference to the following figures and examples.
A monitoring device for capsule damage of a transformer oil conservator comprises a transformer oil conservator 1, a capsule 2, transformer oil 3, an oil conservator opening 4, a connecting pipe 5, a float switch 6, an air release plug 7 and an alarm, wherein the capsule 2 is arranged in the transformer oil conservator 1 and is filled with the transformer oil 3, the upper end of the end surface of the transformer oil conservator 1 is provided with the connecting pipe 5, one end of the connecting pipe 5 is communicated with the transformer oil conservator 1, the other end of the connecting pipe 5 is provided with the float switch 6, the float switch 6 is connected with the alarm, and the float switch 6 is arranged at the highest point of the oil conservator; the connecting pipe 5 of the float switch 6 is provided with an air relief plug 7; the transformer oil conservator 1 is vacuumized and then filled with transformer oil 3, and gas in the transformer oil conservator 1 is discharged through a gas release plug 7 at the position of a float switch 6. Thus, the transformer oil storage cabinet 1 and the float switch 6 are filled with the transformer oil 3, and the capsule 2 is in an expansion state; if the capsule 2 is broken, the capsule 2 is contracted, the oil level of the transformer oil storage cabinet 1 is lowered, the float switch is switched on, and the alarm sends out an alarm signal, so that the purpose of monitoring whether the capsule of the transformer oil storage cabinet is damaged or not is achieved.
The transformer stores up 1 tops of oil tank and is equipped with oil storage tank mouth 4, and capsule 2 is installed in transformer stores up oil tank 1 through storing up oil tank mouth 4, and capsule 2 communicates with the external world through storing up oil tank mouth 4.
The float switch is arranged at the high point of the transformer oil conservator, when the transformer normally runs, the outer side of the capsule in the transformer oil conservator is filled with transformer oil, the inner side of the capsule is communicated with the outside and is filled with dry air, and at the moment, the float switch can not send out an alarm signal; when the capsule is damaged (such as cracking or crevasse) due to some reason, air inside the capsule can enter the transformer oil storage cabinet 1 from the damaged part 8 of the capsule, the pressure difference between the inside and the outside of the capsule disappears, the capsule shrinks, the oil level drops, the float switch is switched on, and the alarm can send out an alarm signal.
