Description

Technical Field

[0001] The invention relates to the field of series compensation type monitors, in particular to a monitor compensation device with series compensation type protection function. Background Art

[0002] A series compensation monitor usually refers to a device used to monitor electrical parameters (such as current, voltage, etc.) in power systems or other industrial systems. Its working principle is to be connected in series in the system to monitor the operating status of the system in real time and compensate for various deviations or problems that may occur in the system. The design of the series compensation monitor is generally able to monitor the operating parameters of the system in real time, such as current, voltage, power, etc., and can compensate for fluctuations or interference in the power system to ensure stable operation of the system.

[0003] For series-compensated monitors, heat dissipation requirements are very important because they usually need to handle larger currents or powers and may operate in high-temperature environments. Poor heat dissipation can cause the device to overheat, affecting its performance and life, and may even cause failures. For this reason, we propose a monitor compensation device with series-compensated protection function. Summary of the invention

[0004] In order to solve the above problems, the present invention adopts the following technical scheme: a monitor compensation device with series compensation protection function, including a device body, the device body includes a monitor circuit board, a lower box body and an upper cover plate, the lower box body has mounting holes on both sides, and air induced components are detachably installed in the two mounting holes, and a plurality of fans are installed in the air induced components, and a plurality of guide main boards are fixedly connected to the bottom surface of the upper cover plate, and a heat dissipation channel is formed between two adjacent guide main boards, and the two ends of the heat dissipation channel are respectively facing the air induced components on both sides, and a plurality of guide sub-plates are arranged on both sides of the heat dissipation channel, and the plurality of guide sub-plates are arranged along the length direction of the guide main board, and the guide sub-plate includes fixed ends at both ends and a free end in the middle, and the two fixed ends are fixedly connected to the guide main board, and the guide sub-plate is metal The thin plate is made of a material, the guide sub-plate absorbs heat and expands so that the free end bulges outward, a control unit is installed in the device body, the control unit is electrically connected to the fan, a first temperature sensor is arranged on the outside of the air induced component, the control unit can compare the signals from the two first temperature sensors, and send out a first control signal according to the comparison result, and the first control signal can change the rotation direction of the fan; the first control signal sent by the control unit can control the fan on the side with lower temperature to inhale air and the fan on the other side to exhaust air, so that a cold-in-hot-out airflow is formed in the heat dissipation channel, the guide sub-plate absorbs the heat expansion in the device body, and its free end bulges outward, so that the heat dissipation channel becomes narrow, thereby accelerating the speed of airflow circulation and increasing the heat dissipation effect there, and the detachable air induced component is convenient for maintenance and replacement.

[0005] Furthermore, the structures of the two air induced components are exactly the same, the number of fans arranged in the air induced components is the same as the number of heat dissipation channels, and the heat dissipation channels are arranged in parallel between the fans on both sides; when the fans are working, the airflow direction is facing the heat dissipation channels, ensuring that the airflow velocity can meet the heat dissipation requirements.

[0006] Furthermore, a plurality of second temperature sensors are evenly spaced in the heat dissipation channel, and the second temperature sensors arranged in the same heat dissipation channel are electrically connected to the fans at both ends of the heat dissipation channel. The control unit can send a second control signal based on the signal received from the first temperature sensor, and the second control signal can adjust the rotation speed of the two fans at the same time; the fans at both ends of the heat dissipation channel where the temperature is higher increase their rotation speed under the action of the second control signal, thereby accelerating the airflow velocity and improving the heat dissipation effect.

[0007] Furthermore, the air induced component includes an outer shell and a mounting frame, a first connecting edge is provided in the mounting hole, and the mounting frame can be embedded in the mounting hole and connected to the first connecting edge; the design of the mounting frame embedded in the mounting hole enables the side wall of the lower box body to form a plane, thereby preventing the air induced component from being damaged by bumps due to the protrusion of the air induced component.

[0008] Furthermore, the installation frame includes a first installation frame and a second installation frame, the first installation frame is arranged at the front part of the outer shell, the second installation frame is arranged at the inner wall of the first installation frame, the second installation frame is installed on the first installation frame, a dustproof net is arranged between the first installation frame and the second installation frame, and the second installation frame can press and fix the four sides of the dustproof net in the second connecting edge; the first installation frame and the second installation frame are installed together so that the dustproof net can be pressed in the second connecting edge, and the second installation frame can be removed, so that the dustproof net that is clogged due to long-term use can be removed for cleaning and replacement.

[0009] Furthermore, the guide main board is made of copper or stainless steel, the thickness of the guide main board is greater than 4mm, the expansion coefficient of the guide sub-board is 22ppm / ℃ to 25ppm / ℃, and the thickness of the guide sub-board is 0.8mm to 1.2mm; the guide main board made of copper or stainless steel has a higher expansion coefficient than the guide sub-board, and has high hardness and is not easy to deform. The guide sub-board expands after absorbing heat. Since the fixed ends at both ends are fixed to the side walls of the guide main board, the free end in the middle can bulge outward, thereby making the heat dissipation channel narrower, and the higher the temperature, the narrower the heat dissipation channel, the faster the air flow speed at this location, and the better the heat dissipation effect.

[0010] Furthermore, first grooves are provided on both sides of the second mounting frame, second grooves matching the first grooves are provided on both sides of the mounting hole, a baffle is rotatably connected to the second groove through a connecting shaft, and the baffle can prevent the air induced assembly from detaching from the mounting hole, a spring is provided between the mounting frame and the first connecting edge, and one end of the spring is fixedly connected to the mounting frame; the air induced assembly is installed in the mounting hole, and the baffle is rotated to make one end of it press into the first groove to prevent the air induced assembly from detaching, and the spring is in a compressed state between the second mounting frame and the first connecting edge, and when the baffle is rotated away from the first groove, the spring releases its elastic force to pop the air induced assembly out of the mounting hole for easy disassembly.

[0011] Furthermore, the dustproof net is a film made of polyester fiber material, and the outer side of the dustproof net has an antistatic coating; the dustproof net is made of polyester fiber material and is provided with an antistatic coating, both of which can prevent dust from adhering to the surface of the dustproof net.

[0012] Furthermore, a plurality of connecting ears are fixedly connected to the inner wall of the shell, a first connecting hole is opened on the connecting ear, and second connecting holes are arranged at the four corners of the fan, the second connecting holes are respectively matched with the first connecting holes, the first connecting hole and the second connecting hole are threadedly connected by bolts, the connecting ears are made of rubber material, and a nut is installed at the front end of the bolt; the vibration generated when the fan rotates is absorbed by the connecting ears made of rubber material, thereby effectively reducing the noise generated when the fan rotates.

[0013] Furthermore, the bottom of the lower box body is provided with heat dissipation fins, and the heat dissipation fins and the lower box body are an integrally formed structure; the heat dissipation fins are arranged at the bottom to prevent dust from accumulating between the heat dissipation fins and being difficult to clean.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, when the guide sub-plate absorbs the heat expansion in the device body, its free end bulges outward, making the heat dissipation channel narrower, thereby accelerating the speed of air flow and increasing the heat dissipation effect there. When the temperature drops, the guide sub-plate can shrink until it returns to its original length.

[0016] 2. Several second temperature sensors are arranged in the same heat dissipation channel into a group. The second temperature sensors sense the temperature change in the heat dissipation channel. The control unit can send a second control signal according to the temperature sensed by the first temperature sensor. The second control signal can simultaneously adjust the speed of the fans at both ends of the heat dissipation channel. The speed of the fans is positively correlated with the temperature, thereby effectively adjusting the heat dissipation effect.

[0017] 3. The air induced components can be detachably installed on both sides of the lower box body, and the air induced components can be locked by the baffle after installation. When disassembling, the air induced components can be ejected from the installation hole by the spring, making maintenance and replacement more convenient.
