Description

Technical Field

[0001] This utility model relates to the field of electrical component technology, and in particular to a novel relay protection voltage output power amplifier device. Background Technology

[0002] Currently, relay protection voltage output power amplifiers are widely used in the testing and verification of protection equipment in power systems to amplify low-level control signals into standard test voltages. However, existing devices still have the following structural design problems: The housing structure is complex and not very secure: Traditional power amplifier devices mostly use screw encapsulation or integrated welding structure, which is not conducive to quick on-site disassembly and module replacement, and the housing is prone to misalignment or structural deformation during disassembly and assembly. Poorly designed heat dissipation systems and unstable thermal contact: Many devices still rely on fixed aluminum blocks or fans for heat dissipation, lacking reliable heat dissipation clamping structures, which causes power devices to suffer from localized overheating, affecting performance or even causing damage. Lack of an effective installation feedback mechanism: During the installation of heat dissipation devices, it is impossible to accurately determine whether the components are installed in place, which can easily lead to problems such as excessive screwing in of the threads and damaging the internal module units.

[0003] Therefore, we propose a novel relay protection voltage output power amplifier device to solve the existing problems. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a novel relay protection voltage output power amplifier device.

The heat dissipation component adopts a replaceable modular heat dissipation design to dissipate heat from the module unit. The heat dissipation component is equipped with a viewing component, which is used to observe the installation position of the heat dissipation component.

[0006] Preferably, the heat dissipation assembly consists of heat dissipation fins, a heat dissipation base, a round head, a spring, and a heat-conducting plate.

[0008] Preferably, the original length of the spring is greater than the inner wall depth of the heat sink.

[0009] Preferably, the visual component consists of a visual rod, a slider, and a groove. The groove is formed within the heat sink of the heat dissipation component, the slider is slidably disposed within the groove, and the visual rod is disposed on the slider.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] like Figures 1-5 As shown, the present invention proposes a novel relay protection voltage output power amplifier device, including a lower housing 1 and an upper housing 2. The lower housing 1 is provided with a control panel 4 at its head end. A clutch block 9 is slidably inserted between the lower housing 1 and the upper housing 2. The clutch block 9 controls the lower housing 1 and the upper housing 2 to not move up and down. A tail plate 3 is plastically snapped between the lower housing 1 and the upper housing 2. The tail plate 3 controls the lower housing 1 and the upper housing 2 to not move back and forth. The lower housing 1 is provided with a module unit 7, and the upper housing 2 is provided with a heat dissipation component 5. The heat dissipation component 5 adopts a replaceable modular heat dissipation design to dissipate heat from the module unit 7. The heat dissipation component 5 is provided with a viewing component 8, which is used to observe the installation position of the heat dissipation component 5.

[0017] In the assembly process of the relay protection voltage output power amplifier device housing, the upper and lower housings are first placed symmetrically. Then, multiple clutches 9 slide between the two housings. The clutches 9 control the upper and lower housings to prevent them from moving away from each other vertically. Then, the tail plate 3 is snapped into the space between the upper and lower housings. The tail plate 3 controls the upper and lower housings to prevent them from moving away from each other front and back, thus completing the housing assembly. The housing protects the core module unit 7 of the output power amplifier. Then, heat dissipation component 5 is assembled. Heat dissipation component 5 dissipates heat from module unit 7. The installation of heat dissipation component 5 can be observed through visual component 8. Example

[0018] like Figures 1-5As shown, this utility model proposes a novel relay protection voltage output power amplifier device. Compared with Embodiment 1, this embodiment further includes: a heat dissipation assembly 5 composed of heat dissipation fins 501, a heat dissipation base 502, a round head 503, a spring 504, and a heat-conducting plate 505. The heat-conducting plate 505 rests on the heat dissipation surface of the module unit 7. The round head 503 is located at the center of the heat-conducting plate 505. The heat dissipation base 502 is threaded onto the upper housing 2. The round head 503 is inserted into the bottom end of the inner wall of the heat dissipation base 502, and the spring 504 is located between the round head 503 and the top end of the inner wall of the heat dissipation base 502. Each heat dissipation fin 501 is equidistantly arranged on the upper surface of the heat dissipation base 502. The original length of the spring 504 is greater than that of the heat dissipation base 501. The inner wall depth of 2, during the assembly process of heat dissipation component 5, heat conduction plate 505 is laid at the designated position of module unit 7, and then heat sink 502 is threaded on the upper shell 2. At this time, the round head 503 on heat conduction plate 505 is inserted into heat sink 502 and squeezes spring 504. When heat sink 502 is threaded in place, the lower surface of heat sink 502 is in contact with heat conduction plate 505, and under the elastic force of spring 504, heat conduction plate 505 is in close contact with heat dissipation surface of module unit 7. Furthermore, a layer of thermally conductive silicone grease can be applied to each contact surface of heat sink 502, heat conduction plate 505 and module unit 7. Under the action of heat conduction, heat is dissipated to the outside through heat dissipation fins 501.

[0019] The visual component 8 consists of a visual rod 801, a slider 802, and a groove 803. The groove 803 is formed inside the heat sink 502 of the heat dissipation component 5. The slider 802 is slidably disposed in the groove 803. The visual rod 801 is disposed on the slider 802. Through the design of the visual component 8, when the heat sink 502 is installed, when the heat conduction plate 505 is pressed, the heat conduction plate 505 abuts against the visual rod 801 and moves upward in the groove 803 through the slider 802. When the top of the visual rod 801 is flush with the upper surface of the heat sink 502, it indicates that the heat sink 502 is threadedly installed in place, avoiding excessive thread feed of the heat sink 502 from damaging the module unit 7.

[0020] Rotating frames 10 are provided at the four corners of the lower surface of the lower housing 1. Support legs 6 are rotatably mounted on the rotating frames 10. The design of the support legs 6 makes it convenient for the device to be suspended in the air.

[0021] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
