Description

Technical Field

[0001] The present invention relates to the technical field of transformer equipment, and more specifically, to a protection system for transformer equipment. Background Art

[0002] A box-type transformer, also known as a box transformer, integrates a traditional transformer in a box-type housing and is usually placed in places such as residential communities, commercial centers, light stations, airports, factories, mines, enterprises, hospitals, and schools. The main functions of the transformer are: voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Secondly, transformers generally work all year round, and continuous operation throughout the year generates a large amount of heat.

[0003] Especially for transformers near construction sites, due to the lack of shielding around them, the temperature of the transformers is too high in summer, affecting the normal operation of the transformers. The existing transformer cooling structures are simple, and the cooling effect is not ideal except on rainy days. How to utilize rainwater for cooling is an urgent problem to be solved at present; moreover, when large-scale equipment is being constructed near the transformers at construction sites, the vibration force they receive is relatively large, resulting in easy damage to their internal components and affecting the service life of the transformers.

Detailed implementation manners

[0028] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0029] Refer to Figure 1 and Figure 2As shown in the figure, the present invention provides a transformer equipment protection system, which includes a box-type transformer 100, and also includes a reinforced concrete base plate 400 and a water-falling roof 110. The box-type transformer 100 is located on the reinforced concrete base plate 400. Water tanks 500 are fixedly installed on both lower sides of the box-type transformer 100 for storing rainwater. A plurality of lateral elastic supports 510 are fixedly installed on the outer side of the water tank 500. The box-type transformer 100 is connected to the reinforced concrete base plate 400 through the lateral elastic supports 510. The lateral elastic supports 510 can buffer the vibration of the box-type transformer 100, thereby extending the service life of its internal components. The reinforced concrete base plate 400 is fixed to the ground through reinforcement anchor rods 410. The cross-section of the water-falling roof 110 is triangular, and the water-falling roof 110 is fixedly installed on the top of the box-type transformer 100. A blowing device 600 is fixedly installed inside the water-falling roof 100. A air volume regulating mechanism 700 is connected and installed at the lower part of the blowing device 600. Ventilation openings 130 are provided at the upper positions on both sides of the box-type transformer 100. A air volume drying device 800 is fixedly installed on the inner side wall of the box-type transformer 100 at the position of the ventilation opening 130. The air volume drying device 800 can dry the air entering the box-type transformer 100, thereby reducing the humidity inside the box-type transformer 100. A temperature sensor 150 and a humidity sensor 160 are fixedly installed on the inner top of the box-type transformer 100. Water receiving troughs 200 are fixedly installed on both upper sides of the box-type transformer 100. When it rains, the rainwater can slide onto the water receiving troughs 200 on the water-falling roof 100. A circulating water heat dissipation pipe fitting 300 is connected and communicated between the water receiving trough 200 and the water tank 500. A water cavity 140 is provided inside the bottom plate of the box-type transformer 100. A water pump 170 is fixedly installed inside the water cavity 140. The water inlet end and the water outlet end of the water pump 170 are respectively connected and communicated with the water tank 500 and the circulating water heat dissipation pipe fitting 300. The circulating water heat dissipation pipe 300 can circulate the rainwater in the water tank 500 on the side of the box-type transformer 100, thereby achieving the effect of heat dissipation and reducing the internal temperature of the box-type transformer 100. The temperature sensor 150 and the humidity sensor 160 control the water pump 170, the blowing device 600 and the air volume regulating mechanism 700 through a PLC.

[0030] In this embodiment, a convex limit seat 420 with an integral structure is provided in the lower middle part of the reinforced concrete base plate 400. The convex limit seat 420 is inserted into the ground. A middle elastic support 510 is placed inside the convex limit seat 420. The top of the middle elastic support 510 is fixedly connected to the bottom of the box-type transformer 100. The middle elastic support 510 plays a supporting role to ensure the stability of the box-type transformer 100 on the reinforced concrete base plate 400, and the middle elastic support 510 can also play a buffering role to further reduce the longitudinal vibration force of the box-type transformer 100.

[0031] In this embodiment, the circulating water cooling pipe fitting 300 includes branch pipes 330 and a plurality of water pipes 310. The plurality of water pipes 310 are respectively connected to the water tank 500 and the water receiving tank 200 in a communicating manner. As Figure 7 shown, a convex heat dissipation sandwich plate 320 with an integral structure protrudes outward from one side of the water pipe 310. The convex heat dissipation sandwich plate 320 is fixedly inserted into the box-type transformer 100. A drain channel 190 is opened in the bottom plate of the box-type transformer 100 above the water cavity 140. The middle of the drain channel 190 is connected to the water outlet end of the water pump 170 in a communicating manner. Both ends of the branch pipe 300 are respectively connected to the drain channel 190 and the water receiving tank 200 at the corresponding position. When the temperature sensor 150 detects that the temperature in the box-type transformer 100 exceeds the threshold value, it controls the water pump 170 to start through the PLC. The water pump 170 can transport the rainwater in the water cavity 140 into the branch pipe 300. The branch pipe 300 sends the rainwater into the water receiving tank 200, and then circulates into the water tank 500 through the water pipe 310. During the circulation process, the rainwater can enter the convex heat dissipation sandwich plate 320. Since the convex heat dissipation sandwich plate 320 is inserted into the box-type transformer 100, it can absorb the heat in the box-type transformer 100, and then complete the heat exchange through the circulating rainwater, thereby reducing the internal temperature of the box-type transformer 100.

[0032] Refer to Figure 2 shown. In this embodiment, the lateral elastic support 510 includes a plurality of positioning platforms 511 and a U-shaped support seat 512. The plurality of positioning platforms 511 are fixedly installed on the upper part of the reinforced concrete base plate 400. The U-shaped support seat 512 is fixedly installed on the outside of the water tank 500. The positioning platform 511 is inserted into the U-shaped support seat 512 at the corresponding position. A longitudinal buffer spring 513 is fixedly installed between the top of the positioning platform 511 and the inner top of the U-shaped support seat 512. A transverse buffer spring 514 is fixedly installed between the side of the positioning platform 511 and the inner wall of the U-shaped support seat 512. Through the elastic action of the longitudinal buffer spring 513 and the transverse buffer spring 514, the longitudinal and transverse vibration forces received by the box-type transformer 100 can be buffered.

[0033] In this embodiment, a rain sensor 120 is fixedly installed on the top of the rainwater storage bin top 110. The rain sensor 120 can detect whether it is raining. An electric top cover mechanism 210 is movably installed on the top of the water receiving tank 200. The electric top cover mechanism 210 is used to control the opening and closing of the upper opening of the water receiving tank 200. When it is in the closed state, it can reduce the evaporation amount of the rainwater in the water receiving tank 200 and the water tank 500, and ensure that the rainwater can be stored for a long time. The rain sensor 120 controls the start and stop of the electric top cover mechanism 210 through the PLC. When it is raining, the rain sensor 120 controls the electric top cover mechanism 210 to start through the PLC. At this time, the top of the water receiving tank 200 is in the open state, and the rainwater can enter the water receiving tank 200.

[0034] Refer to Figure 5 As shown, in this embodiment, the electric top cover mechanism 210 includes a cover plate 213, an electric push rod 212, and a waterproof cylinder 211. The cover plate 213 is movably and hingedly installed above the water receiving tank 200. One end of the cover plate 213 extends outside the water receiving tank 200. The waterproof cylinder 211 is fixedly installed outside the water tank 200. The electric push rod 212 is fixedly installed inside the waterproof cylinder 211. The piston rod of the electric push rod 212 movably penetrates through the top of the waterproof cylinder 211. The piston rod of the electric push rod 212 is movably hinged to the extended end of the cover plate 213. The rain sensor 120 controls the start and stop of the electric push rod 212 through a PLC. When the piston rod of the electric push rod 212 contracts, the cover plate 213 can be flipped. At this time, the upper opening of the water receiving tank 200 is in an open state, ensuring that rainwater can enter the water receiving tank 200.

[0035] Refer to Figure 3 As shown, in this embodiment, the blowing device 600 includes a wind hood 610 and a blower 620. The wind hood 610 is fixedly installed inside the top of the water falling bin 110. Air outlets 630 are provided on both sides of the wind hood 610. The blower 620 is fixedly installed inside the wind hood 610. A plurality of fan-shaped air inlets 180 are symmetrically arranged at the bottom of the wind hood 610 around the axis. When the temperature sensor 150 detects that the temperature exceeds the threshold and the humidity sensor 160 detects that the humidity exceeds the threshold, the blower 620 is turned on. The blower 620 can blow the dried air into the box-type transformer 100 to increase the internal air flow velocity, achieving a cooling effect and also a dehumidifying effect.

[0036] Refer to Figure 3 and Figure 8As shown, in this embodiment, the air volume regulation mechanism 700 includes a receiving cylinder 710, a threaded cover 720, a motor 730, and a turntable 740. The receiving cylinder 710 is fixedly installed on the inner top of the box-type transformer 100. The receiving cylinder 710 is communicated with the air inlet 180. The threaded cover 720 is in threaded fit connection with the receiving cylinder 710. The motor 730 is fixedly installed inside the threaded cover 720. The turntable 740 is fixedly connected to the output shaft of the motor 730. The turntable 740 is in contact with the air inlet 180. A plurality of sector-shaped openings 750 are symmetrically arranged on the surface of the turntable 740 around the axis. An air outlet 760 is opened at the bottom of the threaded cover 720. The humidity sensor 160 and the temperature sensor 150 control the start and stop of the motor 730 and the fan 620 through the PLC. When the temperature sensor 150 detects that the temperature exceeds the threshold, and the humidity sensor 160 detects that the humidity exceeds the threshold, the PLC starts the motor 730. The motor 730 is a servo motor and can accurately control the rotation angle. At this time, the sector-shaped openings 750 on the turntable 740 are flush with the air inlet 180, and the air blown by the fan 620 can enter the box-type transformer 100 through the air outlet 760. When the temperature sensor 150 detects that the temperature does not exceed the threshold, and the humidity sensor 160 detects that the humidity does not exceed the threshold, the motor 730 controls the turntable 740 to block the air inlet 180, thereby preventing air from entering the box-type transformer 100.

[0037] Refer to Figure 4 As shown, in this embodiment, the air volume drying device 800 includes a drying box 810. The drying box 810 is fixedly installed on the inner side wall of the box-type transformer 100. A draw opening 820 is opened on one side of the drying box 810. A draw plate 830 is inserted into the draw opening 820. A plurality of desiccant packages 840 are placed on the draw plate 830. An air inlet 180 communicating with the top of the water falling bin 110 is opened at the top of the drying box 810. The air entering the drying box 810 can be dried by the desiccant packages 840, reducing the humidity of the air.

[0038] Refer to Figure 6 As shown, in this embodiment, the middle elastic support 430 includes a frustum steel cover 431, a limiting ring 432, a sliding column 443, and a middle support spring 434. The frustum steel cover 431 is placed inside the protruding limit seat 420. The frustum steel cover 431 is in the shape of a cylinder with a thinner upper part and a thicker lower part and can be stably supported inside the protruding limit seat 420. The limiting ring 432 is fixedly installed on the top of the frustum steel cover 431. The sliding column 443 is fixedly installed in the middle of the lower surface of the box-type transformer 100. The lower end of the sliding column 443 is movably inserted into the frustum steel cover 431. The support spring 434 is sleeved on the surface of the sliding column 443, and the support spring 434 plays a role in buffering the longitudinal vibration force.

[0039] Refer to Figure 2 and Figure 9As shown, in this embodiment, vibration sensors 515 are provided on the inner sides of the U-shaped support seats 512 on both sides, which are used to detect the vibration quantity and transmit the detected vibration quantity to the cloud platform 900 (background) through a separate network module 516 in combination with the unique number of the box-type transformer 100. The cloud platform 900 includes a processing module 901 and a preset vibration model 902. Among them, the processing module 901 processes the vibration quantities of the two vibration sensors into three groups of data. The three groups of data include the vibration quantity on each side (which can be the vibration curve within a set time) and the average vibration quantity (which can be the average vibration curve within a set time). First, the vibration quantity data on each side are transmitted into the vibration model for identification to obtain a first identification result. Then, verification is performed based on the average vibration quantity (the average vibration quantity can effectively balance the error caused by the asymmetric installation of the vibration sensors 515), that is, the average vibration quantity is input into the vibration model for identification to obtain a verification result. The first identification result is corrected according to the verification result (for example: if the error between the verification result and the first identification result is within a reasonable range, the second identification result is equal to the first identification result; if the error is outside the set threshold, the verification result is used as the second identification result), and a second identification result is obtained. This second identification result is the cause of the vibration. The background management personnel can give an early warning or perform manual intervention on the cause of the vibration of the box-type transformer 100 according to the second identification result to reduce the probability of recurrence.

[0040] Among them, the preset vibration model is obtained through training based on the vibration curves caused by known reasons. The specific training process includes: First, collect the vibration curves and the set of causes of vibration that can be obtained, and preprocess the set (for example: intercept the vibration curve within a set time period); then use the set as a training set and train through a neural network to obtain a vibration model. Specifically, when in use, the vibration model can be optimized by adding new vibration curves and the causes of vibration in a timely manner.

[0041] In the present invention, water tanks are fixedly installed at the lower parts on both sides of the box-type transformer, and a plurality of lateral elastic support members are fixedly installed on the outer sides of the water tanks. The box-type transformer is connected to the reinforced concrete base plate through the lateral elastic support members. The lateral elastic support members can buffer the vibration of the box-type transformer, thereby extending the service life of its internal components; a wind volume drying device is fixedly installed at the ventilation port position on the inner side wall of the box-type transformer, and the wind volume drying device can dry the air entering the box-type transformer, thereby reducing the humidity inside the box-type transformer; water receiving troughs are fixedly installed at the upper parts on both sides of the box-type transformer. When it rains, the rainwater can slide onto the water receiving troughs on the top of the water storage bin. The circulating water cooling pipe fittings can circulate the rainwater in the water tank laterally around the box-type transformer, thereby achieving a cooling effect and reducing the internal temperature of the box-type transformer. It can store and utilize rainwater for cooling well, reduce energy consumption, and improve the cooling effect.
