Description

Technical Field

[0001] The utility model relates to the technical field of transformer monitoring, in particular to an online monitoring device for a transformer. Background Art

[0002] Power transformers are one of the most important equipment in the power grid. Maintaining the normal operation of transformers is related to the safety of the entire power grid. However, transformers are affected by electrical, chemical, mechanical, thermal and environmental stresses during operation, which can lead to winding and core failures. Transformer failures have a great impact on the power grid. Once a sudden accident occurs during the operation of a large power transformer, it may cause a large-scale power outage, causing serious adverse social impacts and economic losses. In addition, the maintenance cost of power transformers is high and the cycle is long, and the various economic losses generated are also huge;

[0003] A Chinese patent publication (publication number: CN220508103U) discloses an online monitoring device for a transformer, which includes a bottom plate, four rubber blocks are fixedly connected to the four corners of the upper surface of the bottom plate, a seat plate for placing the transformer is fixedly connected to the top of the four rubber blocks, a displacement sensor for monitoring the displacement of the seat plate is fixedly connected to the middle of the bottom plate, and a locking mechanism for fixing the transformer on the upper surface of the seat plate is provided on the upper surface of the seat plate. The utility model causes relative displacement between the bottom plate and the seat plate through the vibration generated during the operation of the transformer. The greater the amplitude of the vibration, the greater the displacement between the bottom plate and the seat plate. The displacement sensor continuously monitors the displacement between the two. When the displacement amplitude between the two is large, it can be known through the terminal, which is convenient for timely maintenance of the transformer. However, in actual use, when the transformer is short-circuited and damaged and causes a fire, it is not convenient to monitor the fire in time, and it is impossible to handle the fire in an emergency, resulting in safety hazards and economic losses caused by the burning of the transformer, which is not conducive to the monitoring and use of the transformer. For this reason, an online monitoring device for the transformer is proposed. Utility Model Content

Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, the embodiment of the utility model provides an online monitoring device for a transformer, comprising a supporting mechanism 1 and a monitoring mechanism 2;

[0026] The monitoring mechanism 2 is installed on the top of the supporting mechanism 1, and the monitoring mechanism 2 also includes two fixing frames 21;

[0027] Eight fire extinguishing balls 23 are symmetrically fixedly connected to the lower surface of the fixing frame 21 , and four smoke sensors 24 are symmetrically fixedly installed on the fixing frame 21 .

[0028] In one embodiment, the support mechanism 1 also includes two U-shaped cross plates 11, and an angle sensor 25 is fixedly installed on one side of the U-shaped cross plate 11; through the setting of the angle sensor 25, when the vibration amplitude of the U-shaped cross plate 11 is large and the inclination angle of the U-shaped cross plate 11 is monitored to exceed the monitoring error range, the monitoring data is sent to the receiving terminal, and the staff can understand it through the terminal, which is convenient for detection and maintenance of the transformer.

[0029] In one embodiment, two support plates 12 are symmetrically fixedly connected to the upper surfaces of the two U-shaped horizontal plates 11 , and the four support plates 12 are respectively installed at the four bottom corners of the fixing frame 21 ; the fixing frame 21 is supported by the setting of the support plates 12 .

[0030] In one embodiment, four sleeves 22 are symmetrically fixedly connected to the lower surface of the fixing frame 21, and the four sleeves 22 correspond to the four support plates 12, and the four support plates 12 are respectively inserted into the inner walls of the four sleeves 22; through the setting of the sleeve 22, the top of the support plate 12 is inserted into the sleeve 22 at the bottom of the fixing frame 21, so that the fixing frame 21 is installed, and the disassembly and assembly of the fixing frame 21 is convenient.

[0031] In one embodiment, the lower surfaces of the two U-shaped horizontal plates 11 are symmetrically fixedly connected with two connecting plates 13, and the adjacent sides of the four connecting plates 13 are fixedly connected with clamps 14; through the setting of the clamps 14, the clamps 14 fit with the mounting columns, making it convenient to install and fix the connecting plates 13.

[0032] In one embodiment, a first threaded hole 15 is formed on one side of each of the four clamps 14, and a bolt 16 is threadedly connected to the inner wall of the first threaded hole 15; by setting the bolt 16, the bolt 16 is inserted into the first threaded hole 15 of the clamp 14 to fix the position of the clamp 14, thereby fixing the position of the connecting plate 13 and installing the two U-shaped cross plates 11.

[0033] In one embodiment, two second threaded holes 17 are symmetrically provided on the upper surfaces of the two U-shaped horizontal plates 11; through the setting of the second threaded holes 17, the transformer to be installed is moved to the two U-shaped horizontal plates 11, and then the mounting holes on the transformer are aligned with the second threaded holes 17, so as to facilitate the installation and fixation of the transformer.

[0034] When the utility model is working: first, fit the clamp 14 with the installation column, then insert the bolt 16 into the first threaded hole 15 of the clamp 14, fix the position of the clamp 14, thereby fix the position of the connecting plate 13, install the two U-shaped horizontal plates 11, move the transformer to the two U-shaped horizontal plates 11, align the mounting holes on the transformer with the second threaded holes 17, and facilitate the installation and fixation of the transformer. After the transformer is installed and fixed, move the fixing frame 21 to the top of the four support plates 12, then insert the top of the support plate 12 into the sleeve 22 at the bottom of the fixing frame 21, and install the fixing frame 21. When a fault occurs inside the transformer and abnormal vibration occurs, the U The vibration amplitude of the U-shaped horizontal plate 11 is large. When it is monitored that the inclination angle of the U-shaped horizontal plate 11 exceeds the monitoring error range, the monitoring data is sent to the receiving terminal. The staff learns through the terminal, which is convenient for detection and maintenance of the transformer. When the transformer catches fire, the smoke generated by the fire is monitored by the smoke sensor 24, and the monitoring data is sent to the terminal. The staff learns in time that the transformer has caught fire through the terminal, and goes to the location of the transformer to extinguish the fire in time. At the same time, the fire extinguishing ball 23 explodes due to the high temperature caused by the fire in the transformer. The fire extinguishing material in the fire extinguishing ball 23 covers the transformer, and the transformer is subjected to emergency fire extinguishing, which weakens the fire of the transformer and buys time for the staff to extinguish the fire.

Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
