Description

Technical Field

[0001] This utility model belongs to the field of power transformer technology, and specifically relates to a power transformer intensive care unit. Background Technology

[0002] Power transformers are core equipment in power systems used to transform AC voltage and transmit electrical energy. Their function is to convert one level of AC voltage into another or several levels of AC voltage at the same frequency through the principle of electromagnetic induction to meet the needs of electrical energy transmission, distribution, and use. As a core component of the power system, the stability of the power transformer's operating status directly affects the safety and reliable power supply of the entire power grid. Current technologies employ various methods to monitor the operating status and potential faults of power transformers, such as chromatographic analysis of transformer oil to determine its normal operation. However, when abnormal data is detected in a certain section of transformer oil monitoring, residual transformer oil from previous monitoring may remain inside the oil pipes. This can lead to oil sample mixing and contamination in subsequent monitoring, causing potentially acceptable oil samples to fail tests due to contamination. This hinders the standardization of monitoring data and affects the use of power transformers for critical monitoring.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-7 As the first embodiment of this utility model:

[0034] A power transformer intensive care device includes: a transformer 100, the transformer 100 including a transformer body 101, an oil pipe seat 103 and a suction pipe 104, and the oil pipe seat 103 is fixedly connected to the left rear side of the transformer body 101.

[0035] The inner side of the oil pipe seat 103 is provided with a suction pipe 104 for sucking transformer oil from the transformer body 101. Both the upper and lower sides of the suction pipe 104 are provided with a set of clamping components 300 for clamping the suction pipe 104. A monitoring component 200 is installed on the rear side of the oil pipe seat 103. The monitoring component 200 includes a monitoring box 201, a guide pipe 203, a waste oil seat 214, a separation column 212, and a detector 213.

[0036] A guide pipe 203 is fixedly connected to the middle of the upper inner side of the monitoring box 201. A waste oil seat 214 for receiving waste oil is fixedly connected to the lower left of the guide pipe 203 and the monitoring box 201. A separation column 212 for separating various gas components in the insulating oil is provided on the right side of the waste oil seat 214. A detector 213 for detecting gas components is fixedly connected below the separation column 212. A pipeline switching assembly 400 is sleeved on the outside of the guide pipe 203.

[0037] A connecting plate 102 is fixedly connected to the outer front end of the oil pipe seat 103. The connecting plate 102 is fixedly connected to the transformer body 101 by bolts. An oil pipe connector 105 is fixedly connected to the rear side of the suction pipe 104.

[0038] The upper surface of the oil pipe seat 103 has a retaining groove 106 at the rear end. The retaining groove 106 has a retaining screw 107 inside for driving the upper and lower retaining components 300 to move closer or further away at the same time. The retaining component 300 includes a retaining slider 301 and a retaining seat 303.

[0039] The upper surface of the retaining slider 301 is provided with a retaining screw hole 302. The retaining screw 107 is threadedly connected to the retaining screw hole 302. The retaining slider 301 and the retaining groove 106 are mutually movable and fitted. The retaining seat 303 is fixedly connected to the right side of the retaining slider 301. The surface of the retaining seat 303 that is in contact with the suction tube 104 is provided with anti-slip texture. When the retaining screw 107 rotates and cooperates with the retaining screw hole 302, it drives the two sets of retaining components 300 to move closer to the suction tube 104, so that the retaining seat 303 retains and fixes the suction tube 104.

[0040] A connecting pipe 202 is fixedly connected to the upper front end of the monitoring box 201. The connecting pipe 202 is sealed to the oil pipe joint 105. The rear end of the connecting pipe 202 is also connected to the guide pipe 203. The middle section of the guide pipe 203 is a metal corrugated pipe 204.

[0041] The monitoring box 201 has a switching slide 206 on the front rear side. The inner side of the switching slide 206 is provided with a switching screw 207 for driving the pipeline switching assembly 400 to move left and right. The pipeline switching assembly 400 includes a switching slider 401 and a fitting half ring 403.

[0042] A switching screw hole 402 is provided on the left side of the switching slider 401, and the switching slider 401 and the switching groove 206 are movably engaged with each other.

[0043] The switching screw 207 is powered by a motor and is threadedly connected to the switching screw hole 402. The rear end of the switching slider 401 is rotatably connected to two sets of symmetrically arranged fitting half rings 403 via a rotating shaft. The two sets of fitting half rings 403 fit onto the outside of the guide tube 203 and are connected by bolts. The switching screw 207 rotates under the drive of the motor and engages with the switching screw hole 402, thereby driving the guide tube 203 to move left and right to switch to the waste oil seat 214 or the corrugated pipe 210.

[0044] The upper surface of the waste oil holder 214 is provided with a receiving groove 215, and the lower end of the receiving groove 215 is provided with a guide hole 216. The lower end of the guide hole 216 is fixedly connected to the monitoring box 201 with a waste oil conduit 217.

[0045] Specifically, the oil pipe seat 103 is pre-installed and fixed to the transformer body 101 via the connecting plate 102, and the clamping screw 107 rotates and cooperates with the clamping screw hole 302, driving the two sets of clamping components 300 to move closer to the suction pipe 104, so that the clamping seat 303 clamps and fixes the suction pipe 104. After the monitoring component 200 is installed behind the oil pipe seat 103, the connecting pipe 202 is connected and fixed to the suction pipe 104 through the oil pipe joint 105. The suction of transformer oil is realized through the set suction pump and valve structure.

[0046] Secondly, if the previous data test was unqualified, before the next sampling of transformer oil, the switching screw 207 rotates under the drive of the motor and engages with the switching screw hole 402, thereby driving the guide pipe 203 to move left and right to switch to the waste oil seat 214 or the docking corrugated pipe 210. During the discharge of waste oil, it is collected in the receiving groove 215, and then introduced into the waste oil conduit 217 through the guide hole 216. Then, it is discharged centrally through the waste oil conduit 217. The guide pipe 203 does not contact the docking corrugated pipe 210 and the docking sealing ring 211 during the transmission of transformer oil, thereby improving the accuracy of the test data (the separation column 212 and detector 213 used in the test are both mature products in the prior art, and their specific connection methods and usage methods are well known to those skilled in the art, and will not be described in detail here).

[0047] Please see Figure 1 and Figures 3-4 As a second embodiment of this utility model:

[0048] The lower surface of the guide tube 203 is provided with a docking sealing groove 205, the upper end of the separation column 212 is fixedly connected with a docking corrugated pipe 210, and the upper outer side of the docking corrugated pipe 210 is fixedly connected with a connecting seat 209.

[0049] An electric telescopic rod 208 is fixedly connected to the upper right of the connecting seat 209. A set of docking sealing rings 211 is also fixedly connected to the upper end of the docking corrugated pipe 210. The docking sealing rings 211 and the docking sealing groove 205 are sealed and fitted together. When the guide pipe 203 moves to the top of the separation column 212, the docking corrugated pipe 210 is moved upward by the electric telescopic rod 208, so that the docking sealing rings 211 and the docking sealing groove 205 are fitted together to complete the sealing docking.

[0050] Based on the first embodiment described above, when the guide tube 203 moves above the separation column 212, the electric telescopic rod 208 drives the docking bellows 210 to move upward, so that the docking sealing ring 211 and the docking sealing groove 205 fit together to complete the sealing docking, thereby reducing the interference of foreign objects entering the transformer oil sample with the detection structure.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
