Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an insulating module with good heat dissipation effect. Background Art

[0002] Insulation modules are primarily used in electrical equipment to ensure safe operation and prevent electrical faults. Specifically, an insulation module consists of an insulating body, which consists of an insulating base plate and an insulating housing, and a power device mounted within a housing. The insulation module is a device used to monitor and detect insulation problems in power systems. It primarily monitors the insulation resistance between the positive and negative poles of a DC system and the ground. When the alarm setting value is reached, it issues a ground fault alarm signal and locates the ground fault branch, thereby speeding up fault handling and ensuring safe operation of the power system. The insulation module plays a vital role in power systems. It not only speeds up ground fault handling and reduces labor intensity, but also shortens the grounding cycle, making power system operation safer.

[0003] At present, most insulation modules are usually used in which the internal power operational amplifier is directly attached to its stainless steel casing. This prevents the heat generated during operation from being dissipated to the outside, thereby affecting the internal components. It also cannot block the external high voltage, which causes the internal components of the device to burn out due to the external high voltage, making it inconvenient to use. In addition, the components in most insulation modules are usually installed and fixed with screws, making it inconvenient to assemble or disassemble for maintenance and repair, and the practicality is relatively poor. Utility Model Content

The setting of the fixing mechanism can conveniently and quickly assemble, install or disassemble the high-voltage side PCB, transformer and low-voltage side PCB, so as to carry out maintenance and repair on them, which is more practical.

[0007] Furthermore, a spring and a pedal are sleeved on the outside of the fixed column in the pressure cover, and the two ends of the spring are fixedly connected to the pedal and the inner wall of the pressure cover respectively, so that the elastic force generated by the spring extrusion pushes the pedal to squeeze the device installed below, thereby pressing and fixing it.

[0008] Furthermore, a limit block is symmetrically provided on the outer wall of one end of the plug, and the limit block is located in chamber one.

[0009] Furthermore, the rotating wheel is oval and a magnet, and the plug is made of a metal material that is attracted to the rotating wheel, so that the rotating wheel can absorb the plug and the plug follows the rotation of the rotating wheel and moves accordingly.

[0010] Furthermore, each inner wall surface of the shell is covered with silicone cloth, the pressure cover is concave, and heat dissipation silicone grease is applied between the ceramic sheet and the heating element, and between the ceramic sheet and the aluminum heat dissipation plate. The setting of the silicone cloth can effectively prevent high pressure around, and can achieve heat dissipation effect, and can dissipate part of the ambient temperature heat.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: Figures 1-4As shown, the utility model provides a technical solution: an insulating module with good heat dissipation effect, comprising a shell 1, in which a high-voltage side PCB2, a transformer 3 and a low-voltage side PCB4 are arranged from left to right, and connecting ears 5 are provided at the four corners of the outer side of the transformer 3. The high-voltage side PCB2, the low-voltage side PCB4 and the connecting ears 5 are all connected to the shell 1 through a fixing mechanism 10, and a nylon pressure plate 6, a heating device 7, a ceramic sheet 8 and an aluminum heat sink 9 are arranged on the right side of the low-voltage side PCB4 in the shell 1 from near to far. There are two heating devices 7, and the two heating devices 7 are symmetrically arranged. In this example, the heating device 7 is a power operational amplifier; through holes are provided on the high-voltage side PCB2, the low-voltage side PCB4, the connecting ears 5, the nylon pressure plate 6 and the ceramic sheet 8, the fixing mechanism 10 includes a fixing cylinder 12, and one end of the fixing cylinder 12 is fixedly connected to the inner wall of the shell 1. In this example, the fixing mechanism 10 also includes a pressure cover 14, and the pressure cover 14 is located on the side of the low-voltage side PCB4. A fixing column 13 is installed inside the pressure cover 14, and the fixing column 13 passes through the through holes on the low-voltage side PCB4 and the nylon pressure plate 6 and is inserted into the fixing cylinder 12. The upper and lower parts of the fixing column 13 are respectively provided with a chamber 24 and a chamber 1 23. A rotating shaft 15 is rotatably installed in the chamber 1 23, and the rotating shaft 15 is connected to a twist handle 16 above the pressure cover 14. The outer wall of the rotating shaft 15 is provided with a rotating wheel in the chamber 1 23. 17, an insert 18 adapted to the rotating wheel 17 is symmetrically provided on the outside of the rotating wheel 17, and the opposite outer end of the insert 18 is inserted into a slot symmetrically provided on the inner wall of the fixed cylinder 12. A torsion spring 19 is sleeved on the outside of the rotating shaft 15 in the second chamber 24, and the two ends of the torsion spring 19 are respectively fixedly connected to the rotating shaft 15 and the inner wall of the second chamber 24. The setting of the fixing mechanism 10 can conveniently and quickly assemble, install or disassemble the high-voltage side PCB 2, the transformer 3 and the low-voltage side PCB 4, so as to facilitate their maintenance and repair, and is more practical. In this example, a spring 20 and a pedal 21 are sleeved on the outside of the fixing column 13 in the gland 14, and the two ends of the spring 20 are respectively fixedly connected to the pedal 21 and the inner wall of the gland 14, so that the elastic force generated by the extrusion of the spring 20 pushes the pedal 21 to squeeze the device installed below, thereby pressing and fixing it.

[0021] In this example, a stopper 22 is symmetrically positioned on the outer wall of one end of the insert 18. Stopper 22 is located within chamber 1 23. Stopper 22 is an arc-shaped structure that conforms to the inner wall of chamber 1 23, limiting and guiding insert 18 and preventing it from accidentally moving outside of the fixed column 13. In this example, the rotating wheel 17 is elliptical and magnetic, and insert 18 is made of a metal material that attracts the rotating wheel 17, allowing it to attract the insert 18 and move accordingly with the rotation of the rotating wheel 17. In this example, silicone tape 11 is applied to each inner wall of the housing 1. The gland 14 is concave. Thermal dissipation silicone grease is applied between the ceramic sheet 8 and the heating element 7, and between the ceramic sheet 8 and the aluminum heat sink 9. The silicone tape 11 effectively isolates the surrounding high pressure and provides a heat dissipation effect, dissipating some ambient heat.

[0022] The working principle of the present invention is as follows: when in use, by setting the aluminum heat sink 9 and the ceramic sheet 8, the heating device 7 is closely fitted to the ceramic sheet 8, and the heat dissipation silicone grease is applied, so that the heat can be fully conducted to the aluminum heat sink 9 through the ceramic sheet 8, and then the heat is dissipated. In combination with the provided silicone cloth 11, it can effectively isolate the external high voltage electricity and have a certain heat dissipation effect, so that it can dissipate the heat inside the shell 1 well, and solve the problem of external high voltage damaging the device; when it is necessary to disassemble the high-voltage side PCB2, the transformer 3 or the low-voltage side PCB4, the twist handle 16 can be twisted to drive the rotating shaft 15 to rotate, so that the rotating shaft 15 twists the torsion spring 19, and at the same time, the rotating shaft 15 will drive the rotating wheel 17 to rotate, so that the rotating wheel 17 moves away from one end of the rotating shaft 15 and gradually moves away from the plug-in block 18. At the same time, the plug-in block 18 moves toward the side close to the rotating wheel 17 under the magnetic attraction of the rotating wheel 17, so that the plug-in block 18 is inserted into the slot and one end is moved out, and then the fixing column 13 is pulled out, and the process is completed. When the PCB 2 is in the state of being assembled, the PCB 2 is assembled and the PCB 2 is in the state of being assembled.
