Description

Technical Field

[0002] Existing box-type transformers are generally equipped with a heat dissipation structure mainly composed of a heat dissipation fan to accelerate the overflow of internal hot air to the outside, thereby achieving a rapid heat dissipation effect. Since the diameter of the heat dissipation port is fixed in the prior art, even with the assistance of a heat dissipation fan, the speed at which the internal hot air flows outward is still limited, resulting in the heat in the substation being difficult to discharge in time. After working for a long time, the long-term heat accumulation can easily lead to excessive heat accumulation and overheating, posing certain safety hazards. Summary of the invention

In addition, in the process of the expansion heat sink collapsing and folding downward, the color-developing liquid in the auxiliary expansion column is squeezed, so that the inner layer of the color-developing ball is squeezed and attached to the outer layer, and then from the outside, the obvious color development phenomenon on the color-developing ball can be visually observed intuitively, which can provide a certain early warning reminder for the staff, facilitating their timely manual intervention and reducing safety hazards.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Embodiment 1:

[0035] See also Figure 1 A heat-regulating box-type substation includes a substation body 1. The front and rear tops of the substation body 1 are both provided with a plurality of evenly distributed main heat dissipation ports 2. The left and right sides of the substation body 1 are both provided with auxiliary heat dissipation ports. An expansion heat dissipation plate 3 is clamped on the inner wall of the auxiliary heat dissipation port. An auxiliary expansion column 4 is provided at the lower end of the expansion heat dissipation plate 3. The auxiliary expansion column 4 is fixedly embedded in the substation body 1.

[0036] See also Figure 2-3 The expansion heat sink 3 includes an outer frame 31 and a self-collapsing cover 32 located in the outer frame 31. The self-collapsing cover 32 is a porous structure and is made of a flexible material. The left and right inner walls of the outer frame 31 are provided with limited slots 10. The self-collapsing cover 32 is slidably connected between the two limited slots 10. Figure 4A plurality of evenly distributed limiting cross bars 33 are fixedly connected to the back of the self-collapsing cover 32, and a plurality of limiting rings 34 are fixedly connected to the middle of the limiting cross bars 33. The upper end of the auxiliary expansion column 4 movably penetrates the outer fixed frame 31 and matches with the plurality of limiting rings 34. When the exposed rod 41 is driven downward by the electric push rod 6, the limiting ring 34 fixed to the exposed rod 41 first drives the limiting cross bar 33 to slide down, so that the upper end of the self-collapsing cover 32 starts to move downward, and the bottom is gradually stacked, so that the auxiliary heat dissipation port is gradually opened. Compared with the shielding of the self-collapsing cover 32, the area available for gas overflow is larger, so that the hot air can overflow faster, effectively avoiding heat accumulation in the substation body 1 and reducing safety hazards.

[0037] See also Figure 5 The expansion-assisting column 4 includes an outer display frame 43 fixedly embedded in the side wall of the substation body 1, an inner sealing rod 42 with an interference fit on the upper end of the outer display frame 43, and an exposed rod 41 fixedly connected to the upper end of the inner sealing rod 42. The exposed rod 41 moves upward from bottom to top and passes through multiple limit rings 34 and is fixed to the uppermost limit ring 34. An electric push rod 6 is fixedly installed between the inner bottom end of the outer display frame 43 and the lower end of the inner sealing rod 42. A color developing ball 5 is connected to the outer end of the expansion-assisting column 4. The color developing ball 5 is located below the inner sealing rod 42. The space surrounded by the lower end of the inner sealing rod 42, the color developing ball 5 and the outer display frame 43 is filled with a color developing liquid. The outer display frame 43 is an opaque color.

[0038] A temperature sensor is installed in the substation body 1. The temperature sensor and the electric push rod 6 are connected to the control center signal in the substation body 1. When the temperature sensor detects that the temperature in the substation body 1 is relatively high, the temperature is lower than the limit of the safe operating temperature of the substation body 1. In specific implementation, the temperature can be controlled to be 10-25°C lower than the limit safe operating temperature. The temperature sensor feeds back the signal to the control center, controls the hollow control electric push rod 6 to shorten, drives the exposed rod 41 to move downward, and makes the self-collapsing cover 32 gradually fold and collapse downward as a whole, thereby exposing the auxiliary heat dissipation port, greatly increasing the caliber for air overflow. At this time, with the original heat dissipation fan, the internal hot air can overflow faster, thereby improving the heat dissipation effect.

[0039] The upper end of the outer display frame 43 has a smaller inner diameter and the lower end has a larger inner diameter, and the longitudinal span of the portion with a smaller inner diameter is not less than 1 / 3 of the length of the outer display frame 43 , so that the inner sealing rod 42 has enough space to move.

[0040] In addition, during the specific implementation, when the self-collapsing cover sheet 32 ​​is completely collapsed and folded, the upper end of the inner sealing rod 42 still does not completely leave the small diameter of the outer display frame 43, which effectively ensures the resetting of the inner sealing rod 42 and effectively ensures that the internal color developing liquid is not easy to overflow.

[0041] The color developing ball 5 includes an outer limit hemisphere 51 fixedly connected to the outer end of the outer display frame 43 and an inner moving layer 52 located in the outer limit hemisphere 51. The mouth of the inner moving layer 52 is fixedly penetrated through the outer display frame 43 and communicated with the outer display frame 43. The outer limit hemisphere 51 and the inner moving layer 52 are both transparent structures, so that the color of the internal color developing liquid can be penetrated through the color developing ball 5. According to the contrast of the depth of the color, the staff can timely understand the temperature conditions in the substation body 1, so that the staff can manually intervene in possible overheating conditions, thereby reducing the losses caused by the burning of some components in the substation due to overheating. The outer limit hemisphere 51 is made of hard material, which effectively limits the expansion limit of the inner moving layer 52, making it difficult to be burst, and effectively protects it from being broken due to unexpected expansion from the outside. The inner moving layer 52 is made of elastic material, and the color developing liquid is a high-brightness color, so that when the inner moving layer 52 is attached to the inner wall of the outer limit hemisphere 51, the color presented is more conspicuous, which is convenient for the staff to find out in time.

[0042] In addition, during the specific implementation, the technicians conducted multiple adjustments so that when the self-collapsing mask 32 is completely collapsed and folded, the color developing solution enters the inner dynamic layer 52 so that more than 80% of its expanded surface is in compression contact with the inner wall of the outer limiting hemisphere 51 .

[0043] When not overheated, the electric push rod 6 does not control the inner sealing rod 42 to move downward, and the color developing liquid has limited extrusion on the inner dynamic layer 52. It naturally droops and does not contact the inner wall of the outer limit hemisphere 51, or only partially contacts the outer limit hemisphere 51, so that the color observed at the outer limit hemisphere 51 is not obvious. The color difference change before and after overheating can be used to warn the staff.

[0044] By the coordinated arrangement of the expansion heat sink 3 and the auxiliary expansion column 4, when the temperature is overheated, Fig. 9 , the expansion heat sink 3 can be automatically controlled to collapse and fold downward, so that the auxiliary heat dissipation port is opened. Compared with the existing technology, the internal area for hot air to overflow is greatly increased, the heat dissipation effect is greatly increased, and the heat accumulation is effectively reduced. The temperature increase rate in the substation body 1 after long-term work is suppressed. In addition, in the process of the expansion heat sink 3 collapsing and folding downward, the color-developing liquid in the auxiliary expansion column 4 is squeezed, so that the inner layer of the color-developing ball 5 is squeezed and attached to the outer layer, and then from the outside, the obvious color development phenomenon on the color-developing ball 5 can be visually observed intuitively, which can play a certain early warning and reminder role for the staff, facilitating their timely manual intervention and reducing safety hazards.

[0045] Embodiment 2:

[0046] The color developing liquid is a colorless liquid, and deionized water can be selected. The space surrounded by the lower end of the inner sealing rod 42, the color developing ball 5 and the outer display frame 43 is also filled with multiple floating balls 9. The upper end of the electric push rod 6 is not fixed to the inner sealing rod 42, and a non-elastic pull rope 8 is fixedly connected between the two. Please refer to Figure 6 , a ball-spacer mesh plate 7 is fixedly connected to the inner wall of the outer display frame 43, the electric push rod 6 movably penetrates the middle of the ball-spacer mesh plate 7, and the ball-spacer mesh plate 7 is located at the lower edge of the mouth of the inner moving layer 52, and the diameter of the mouth of the inner moving layer 52 is 2-5 times the diameter of the floating ball 9, so that the floating ball 9 can smoothly enter and exit the color-developing ball 5, and when squeezed by the inner sealing rod 42, it can enter the color-developing ball 5 after moving downward. At the same time, when the inner sealing rod 42 is reset, the color-developing liquid gradually returns to the outer display frame 43. At this time, the inner moving layer 52, which gradually loses the squeezing force, recovers its deformation, so that the adsorption between the floating ball 9 and the outer limit hemisphere 51 is broken, and at this time, under the action of buoyancy, it gradually floats back to the outer display frame 43, and the color-developing ball 5 becomes colorless again.

[0047] This is the biggest difference between this embodiment and embodiment 1, and the rest is consistent with embodiment 1.

[0048] See also Figure 8 The lower end of the floating ball 9 is fixedly inlaid with a magnetic sheet 91. The floating ball 9 is a hollow structure and is filled with air. The floating ball 9 is made of a dark, light and hard material, so that the overall gravity of the floating ball 9 is small and the buoyancy is large in the color developing liquid, so that the floating ball 9 is concentrated at the bottom of the inner sealing rod 42, so that the color is not easily observed at the color developing ball 5 when it is not overheated. The inner wall of the outer limit hemisphere 51 is fixedly inlaid with multiple magnetic points, and the magnetic points match the magnetic sheet 91. When overheated, the electric push rod 6 controls the inner sealing rod 42 to move downward, which squeezes multiple floating balls. 9 moves downward to enter the color-developing ball 5, and at the same time, the color-developing liquid squeezes the inner dynamic layer 52 to expand it, so that it adheres to the inner wall of the outer limit hemisphere 51. At this time, the magnetic dots on the outer limit hemisphere 51 and the magnetic sheet 91 are adsorbed on each other. Under the joint action of buoyancy and magnetic attraction, the floating ball 9 adheres to the inner wall of the color-developing ball 5. At this time, the outside world can clearly observe that the color-developing ball 5 is colored. Compared with the change in color depth in Example 1, the color-developing ball 5 in this embodiment changes from colorless to colored, the contrast is more obvious, and the warning effect for the staff is better.

[0049] There are two implementation modes, and technicians can choose one according to their needs during specific implementation.

[0050] The above is only a preferred specific implementation manner of the present invention; but the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
