Description

Technical Field

[0001] The utility model relates to the technical field of distribution networks, and specifically relates to a flexible interconnection soft switch for a distribution network with a self-diagnosis function. Background Technique

[0002] The flexible interconnection soft switch for a distribution network is a new type of intelligent power electronic device installed at the traditional connection switch, which can change the distribution network with a traditional closed-loop design and open-loop operation to a flexible closed-loop operation.

[0003] Although the existing flexible interconnection soft switch for a distribution network is provided with a heat dissipation base mechanism to assist, so that the heat dissipation base mechanism can actively take away the heat on the back of the switch body downward, enabling the switch body to maintain good back heat dissipation during power-on operation, it is impossible to know whether the temperature of the conducted air has exceeded the threshold of the maximum temperature that the switch body can withstand, and effective diagnosis cannot be carried out. If the temperature has exceeded the maximum threshold that can be withstood, the switch body will fail, thus increasing the difficulty of maintenance for personnel. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flexible interconnection soft switch for a distribution network with a self-diagnosis function to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the utility model provides a flexible interconnection soft switch for a distribution network with a self-diagnosis function, including a switch body. A circuit board is arranged on the back of the switch body. An induction block is arranged on the side of the circuit board away from the switch body. The induction block is vertically arranged. The induction block is coated with an overheat-melting solid piece. The detection end of the induction block faces the overheat-melting solid piece to detect the coverage area of the overheat-melting solid piece on the induction block.

[0006] Preferably, the induction block includes a base and an infrared sensor. The heat-melting solid piece is coated inside the base. The infrared sensor is arranged on the inner side wall of the base so that the detection end of the infrared sensor faces the heat-melting solid piece.

[0007] It is worth noting that the overheat-melting solid piece is semi-solid mud.

[0008] Optionally, a glass frame is arranged on the side of the base away from the switch body.

[0009] Specifically, a top mounting plate is arranged on the top of the switch body, and a heat dissipation mechanism is arranged on the top mounting plate.

[0010] Preferably, a heat-conducting backboard is fixedly arranged at the bottom of the top-mounted plate. The heat-conducting backboard is arranged on the side of the circuit board away from the switch body. A plurality of heat-conducting holes are formed on the side of the heat-conducting backboard close to the circuit board. A plurality of grid bars are arranged at equal intervals in the heat-conducting backboard. The grid bars face the heat dissipation mechanism, and the heat-conducting holes are communicated with the grid bars.

[0011] It should be noted that a triangular support is arranged at the bottom of the top-mounted plate. The upper side of the triangular support is connected to the top-mounted plate, and the front side of the triangular support is connected to the switch body.

[0012] Specifically, two triangular supports are symmetrically arranged on both sides of the bottom of the top-mounted plate. An L-shaped member is arranged between the two triangular supports. One side of the L-shaped member is connected to the top-mounted plate, and the other side of the L-shaped member is connected to the box wall of the distribution network equipment.

[0013] Compared with the prior art, the beneficial effect of the present utility model is as follows: In the flexible interconnection soft switch of the distribution network with a self-diagnosis function, an external power supply is connected to make the electrical appliance operate. When the temperature rises to exceed the maximum threshold accepted by the overheat-melting solid part, the overheat-melting solid part begins to melt to form a semi-solid state. Due to gravity, the overheat-melting solid part accumulates on the bottom wall of the induction block after melting. At this time, the area of the overheat-melting solid part covered by the induction block decreases. When it is detected by the detection end that the covered area of the overheat-melting solid part is less than the set value, the induction block emits a warning signal and projects it onto the display screen to remind the maintenance personnel. At this time, the maintenance personnel can clean up the overheat-melting solid part in the induction block and cool down the switch body to ensure the normal operation of the switch body. Subsequently, the overheat-melting solid part is evenly applied on the induction block again, and then wait for the next self-diagnosis. In this way, the problem of the switch body failing at high temperature can be avoided, thereby reducing the difficulty of personnel maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-4 shown, a flexible interconnection soft switch for a distribution network with a self-diagnosis function includes a switch body 1. A circuit board 3 is arranged on the back of the switch body 1. A plurality of switches are arranged on the front of the switch body 1. An induction block 4 is arranged on the side of the circuit board 3 away from the switch body 1. The induction block 4 is arranged vertically. The induction block 4 is coated with an overheat melting solid part 5. The detection end of the induction block 4 faces the overheat melting solid part 5 to detect the coverage area of the overheat melting solid part 5 on the induction block 5.

[0021] In the flexible interconnection soft switch for a distribution network with a self-diagnosis function, an external power supply is connected to make the electrical appliance operate. When the temperature rises above the maximum threshold that the overheat melting solid part 5 can withstand, the overheat melting solid part 5 begins to melt to form a semi-solid state. Due to gravity, the melted overheat melting solid part 5 accumulates on the bottom wall of the induction block 4. At this time, the coverage area of the overheat melting solid part 5 covered by the induction block 4 decreases. When it is detected by the detection end that the coverage area of the overheat melting solid part 5 is less than the set value, the induction block 4 emits a warning signal and projects it onto the display screen to remind the maintenance personnel. At this time, the maintenance personnel can clean up the overheat melting solid part 5 in the induction block 4 and cool down the switch body 1 to ensure the normal operation of the switch body 1. Then, the overheat melting solid part 5 is evenly coated on the induction block 4 again, and then wait for the next self-diagnosis. In this way, the problem of the switch body failing at high temperature can be avoided, thus reducing the difficulty of personnel maintenance.

[0022] It should be noted that the induction block 4 includes a base and an infrared sensor. The heat-melting solid piece 5 is smeared inside the base, and the infrared sensor is arranged on the inner side wall of the base so that the detection end of the infrared sensor faces the heat-melting solid piece 5. Specifically, the infrared sensor is installed in the middle of the inner side wall of the base. After the heat-melting solid piece 5 is smeared inside the base, the heat-melting solid piece 5 wraps the infrared sensor. When the heat-melting solid piece 5 overheats and melts and flows downward, the infrared sensor senses the disappearance of the heat-melting solid piece 5 at the current position, thereby sending out a warning signal and projecting it onto the display screen to remind the maintenance personnel. The infrared sensor is electrically connected to the display.

[0023] Preferably, the heat-melting solid piece 5 is semi-solid mud. The semi-solid mud has a solid structure at normal temperature and will become a semi-solid state with fluidity when overheated and melted.

[0024] Specifically, as Figure 2 and 3 shown, a glass frame 6 is provided on the side of the base away from the switch body 1 to prevent the heat-melting solid piece 5 from flowing outside the base. A first threaded hole is opened on the front side of the glass frame 6, and a first screw 7 is threadedly inserted into the first threaded hole. The four first threaded holes are respectively arranged at the four corners of the front side of the glass frame 6.

[0025] Optionally, as Figure 1 and 4 shown, a top mounting plate 8 is provided on the top of the switch body 1, and a heat dissipation mechanism 2 is provided on the top mounting plate 8. The top mounting plate 8 is perpendicular to the switch body 1 so that the heat dissipation mechanism 2 is also perpendicular to the switch body 1. The heat dissipation mechanism 2 is a fan to achieve the purpose of dissipating heat from the circuit board. A second screw 10 is provided on the top of the switch body 1. The number of the second screws 10 is two groups, and the number of each group of the second screws 10 is two. The two groups of the second screws 10 are symmetrically threadedly inserted and arranged on the front side of the switch body. The top mounting plate 8 is installed on the top of the back of the switch body 1, and the top mounting plate 8 is connected to the switch body 1 through the second screw 10. A second threaded hole 9 is opened on the front side of the top mounting plate 8, and the number of the second threaded holes 9 corresponds to the second screw 10. The second screw 10 is threadedly inserted into the second threaded hole 9.

[0026] It should be noted that, as Figure 1 and 4As shown, a heat-conducting backplane 11 is fixedly arranged at the bottom of the top mounting plate 8. The heat-conducting backplane 11 is arranged on the side of the circuit board 3 away from the switch body. A plurality of heat-conducting holes 12 are formed on the side of the heat-conducting backplane 11 close to the circuit board 3. A plurality of grid bars 13 are arranged in the heat-conducting backplane 11 at equal intervals. The length direction of the grid bars 13 is perpendicular to the length direction of the heat-conducting holes 12. The grid bars 13 face the heat dissipation mechanism 2. The heat-conducting holes 12 are communicated with the grid bars 13, and the communication between the heat-conducting holes 12 and the grid bars 13 is more convenient for the heat dissipation mechanism 2 to perform heat dissipation operations.

[0027] Preferably, as Figure 1 and 4 shown, a triangular support member 14 is arranged at the bottom of the top mounting plate 8. The upper side of the triangular support member 14 is connected to the top mounting plate 8, and the front side of the triangular support member 14 is connected to the switch body 1. The triangular support member 14 with a triangular structure has stability and can further stabilize the top mounting plate 8.

[0028] Specifically, two triangular support members 14 are symmetrically arranged on both sides of the bottom of the top mounting plate 8. An L-shaped member 15 is arranged between the two triangular support members 14. One side of the L-shaped member 15 is connected to the top mounting plate 8, and the other side of the L-shaped member 15 is connected to the box wall of the distribution network equipment, so as to install the flexible interconnection soft switch of the distribution network with self-diagnosis function on the box wall of the distribution network equipment. Third threaded holes 16 are formed in both the top mounting plate 8 and the top of the L-shaped member 15, which can be used to cooperate with bolts to achieve fixation. Fourth threaded holes 17 are formed in the other side of the L-shaped member 15, which are used to cooperate with bolts to connect with the box wall of the distribution network equipment.

[0029] Working principle: First, a circuit board 3 is provided on the back of the switch body 1. An induction block 4 is arranged on the circuit board 3. Then, a heat-overheated and melted solid piece 5 with a certain thickness is evenly applied on the base of the induction block 4. The fixing holes on the glass frame 6 are aligned with the fixing holes on the base of the induction block 4 and connected with the first screw 7. At this time, the fourth threaded hole 17 is placed at the box wall of the distribution network equipment and installed and connected with bolts. Then, the top mounting plate 8 is placed and clamped at the other end of the fourth threaded hole 17, and bolts are inserted through the third threaded hole 16 again for installation and fixation. At this time, the switch body 1 is aligned with the second threaded hole 9 on the front side of the top mounting plate 8 and inserted with the second screw 10 for fixation. Then, an external power supply is connected to make the electrical appliance operate. At this time, the heat dissipation mechanism 2 at the top of the switch body 1 starts to work for heat conduction. The heat at the back panel of the switch body 1 can enter between the grid bars 13 of the heat conduction back plate 11 from the heat conduction holes 12. At this time, the wind force of the heat dissipation mechanism 2 blows downward and into the grid bars 13 and takes the heat away from the heat conduction back plate 11 downward. When the switch body 1 operates for a long time, the temperature of the heat dissipation wind gradually rises. When it rises above the maximum threshold that the heat-overheated and melted solid piece 5 can accept, the heat-overheated and melted solid piece 5 starts to melt. Due to gravity, the heat-overheated and melted solid piece 5 accumulates on the inner bottom wall of the glass frame 6 after melting. At this time, the area of the heat-overheated and melted solid piece 5 covered in the base of the induction block 4 decreases. When it is less than the set value, the infrared sensor of the induction block 4 emits a warning signal and projects it onto the display screen to remind the maintenance personnel. At this time, the maintenance personnel can remove the second screw 10 and the first screw 7, clean the heat-overheated and melted solid piece 5 in the glass frame 6, and cool down the switch body 1 to ensure the normal operation of the switch body 1. Then, the heat-overheated and melted solid piece 5 is evenly applied on the base of the induction block 4 again, and then wait for the next self-diagnosis.

[0030] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
