Description

Technical Field

[0001] The invention relates to the technical field of monitoring devices, and in particular to an online monitoring device for dry-type reactor faults. Background Art

[0002] Dry-type reactors refer to reactors in which the components such as resistance, inductance and capacitance are fixed and do not require the addition of electrodes or electrolyte liquid. The characteristics of this type of reactor are that the values ​​of resistance, inductance and capacitance are fixed and will not change due to factors such as temperature, humidity, current, etc., thus having high stability and reliability.

[0003] In the prior art, a Chinese patent with publication number "CN203133208U" discloses an online monitoring device for dry-type reactor faults. By cleverly utilizing the special structure of the dry-type reactor and using two smoke sensors to measure the smoke value, it is possible to determine whether the reactor has failed. This can effectively avoid the influence of smoke in the external environment on the sensor, and the alarm has high accuracy. It can promptly issue an alarm at the early stage of such reactor failure to prevent the danger and loss of reactor explosion, thus solving the problem of the high failure rate of existing dry-type reactors and the lack of online monitoring methods for a long time.

[0004] Existing dry-type inductors may experience local flashover or inter-turn short circuit, which may cause the dry-type inductor to generate smoke. In the solution described above, two smoke sensors are provided on the dry-type inductor to detect the dry-type inductor. However, when smoke is generated at different positions of the dry-type inductor and the smoke cannot float to the position of the smoke sensor along a specified route, the smoke sensor may not be able to detect the smoke in time. Furthermore, when the contact time between the smoke and the smoke sensor is short, the detection mechanism of the sensor may not be activated.

[0043] Embodiment three:

[0044] On the basis of Example 1 and Example 2, the lifting and rotating assembly includes a positioning ring 28 and a mounting ring 29 fixedly mounted on the upper star frame 1, the outer side surface of the positioning ring 28 is provided with an external thread 30, and the inner side surface of the mounting ring 29 is provided with an internal thread 31, the external thread 30 is meshed with the internal thread 31, and the mounting ring 29 is threadedly connected to the positioning ring 28 through the external thread 30 and the internal thread 31, and the smoke sensor 8 is fixedly mounted on the outer side surface of the mounting ring 29, and a rotating ring 35 is rotatably connected to the mounting ring 29, and a bearing 32 is fixedly connected to the upper end surface of the rotating ring 35, and a positioning rod 33 is fixedly connected to the inside of the bearing 32, and the end of the positioning rod 33 away from the bearing 32 passes through the through groove 7 and is fixedly connected to the L-shaped rod 19.

[0045] In this embodiment, when the L-shaped rod 19 is reciprocatingly lifted and lowered, the positioning rod 33 installed on the L-shaped rod 19 will follow the L-shaped rod 19 to reciprocate and lift. When lifted and lowered, the positioning rod 33 will press down or lift up the rotating ring 35 through the bearing 32, and then rotate on the mounting ring 29 through the rotating ring 35. The force acting on the rotating ring 35 will act on the mounting ring 29, and then the internal thread 31 in the mounting ring 29 will engage with the external thread 30 outside the positioning ring 28, so that the mounting ring 29 is in a rotating and lifting state, and the smoke sensor 8 installed on the mounting ring 29 will be in a state of position change inside the dry-type inductor, effectively making the smoke sensor 8 better in contact with the smoke, thereby improving the detection effect of the smoke sensor 8.

[0046] Working principle:

[0047] When in use, the driving motor 10 drives the driving shaft 11 to rotate, and the rotation of the driving shaft 11 drives the fan blades 13 on the connecting shaft 12 to rotate. The airflow generated by the fan blades 13 at the bottom of the dry-type reactor will blow the smoke generated by the local flashover or inter-turn short circuit of the reactor to the position of the smoke sensor 8, so that the smoke sensor 8 can accurately detect the smoke generated by the local flashover or inter-turn short circuit of the reactor, thereby improving the detection effect and sensitivity of the smoke sensor 8;

[0048] When the driving shaft 11 rotates, the reciprocating groove 15 on the driving shaft 11 is used to make the lifting block 16 slide in the sliding groove 22 through the crescent pin 17 and the sliding rod 21, so that the lifting block 16 is in a reciprocating lifting state, and the positioning ring 18 on the lifting block 16 will synchronously drive the tooth plate 20 on the L-shaped rod 19 to reciprocate and lift. At this time, the L-shaped rod 19 will drive the tooth plate 20 to stably lift and lower inside the through groove 7, and then the tooth plate 20 is engaged with the gear 26 on the rotating plate 24, and the rotating plate 24 will rotate through the rotating shaft 23. The airflow generated by the fan plate 27 on the rotating plate 24 can blow the smoke outside the reactor to the inside of the reactor, so that the smoke is concentrated inside the reactor, which is convenient for the smoke sensor 8 to contact with the smoke for a long time during detection, so as to accurately detect the existence and concentration of smoke;

[0049] When the L-shaped rod 19 is lifted and lowered back and forth, the positioning rod 33 installed on the L-shaped rod 19 will follow the L-shaped rod 19 to lift and lower back and forth. At this time, the positioning rod 33 will pass through the through slot 7 to lift and lower back and forth. The positioning rod 33 will press down or lift up the rotating ring 35 through the bearing 32 when lifting and lowering, and then the rotating ring 35 will rotate on the mounting ring 29. The force acting on the rotating ring 35 will act on the mounting ring 29, so that the mounting ring 29 moves outside the positioning ring 28, and then the internal thread 31 in the mounting ring 29 is engaged with the external thread 30 outside the positioning ring 28, so that the mounting ring 29 is in a state of rotation and lifting. The smoke sensor 8 installed on the mounting ring 29 will be in a state of position change inside the dry-type reactor, which effectively makes the smoke sensor 8 better in contact with the smoke, thereby improving the detection effect of the smoke sensor 8;

[0050] When the smoke sensor 8 detects smoke generated in the dry-type reactor, the signal is transmitted to the alarm 9 in a wireless manner, and the sound emitted by the alarm 9 is used to achieve a monitoring effect.
