Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of relays, in particular to a relay working state monitoring device. Background Art
[0002] Relays play a vital role in power systems, automation control, and a wide range of industrial applications. They can not only realize complex logic control functions, but also undertake key duties such as switching loads and providing isolation protection in circuits. Due to their excellent functionality and reliability, relays have become an indispensable part of modern industry.
[0003] However, relays are prone to overheating during long-term operation, especially under high load or harsh environment. Overheating not only directly affects the normal operation of the relay and reduces its service life, but may also cause aging of the insulation material due to untimely heat dissipation. In severe cases, it may even burn and cause safety accidents. In addition, relay overheating may also be a sign of other circuit failures, which need to be discovered and handled in a timely manner.
[0004] At present, the temperature monitoring of relays mainly relies on regular manual inspections or the installation of basic temperature alarms. These methods have obvious blind spots and delays, and cannot achieve real-time monitoring and fine management of relay status. With the advancement of technology and the improvement of safety requirements, effective and real-time temperature monitoring of relays and timely detection and resolution of overheating problems have become an inevitable requirement for the development of the industry.
[0005] Modern monitoring systems need to have high-precision temperature detection capabilities and be able to issue an immediate alarm when the relay begins to overheat. At the same time, such a system should be able to combine with modern communication technology to achieve remote monitoring and data recording for data analysis, trend prediction and remote diagnosis. In addition, intelligent processing and response mechanisms are also important components of modern temperature monitoring systems. They can not only issue an alarm when an overheating signal is detected, but also automatically take corresponding protective measures according to preset strategies to ensure the stable operation of the system and the safety of personnel. In view of this, we propose a relay working status monitoring device. Utility Model Content

[0028] See also Figure 1-Figure 4 , the utility model provides a technical solution:
[0029] The relay working state monitoring device comprises a relay body 1, which is the core of the device and is responsible for executing the task of switching the circuit. A wiring seat 2 is provided on the rear side of the relay body 1 for installing and fixing the wires to ensure the stability of the electrical connection. An operation panel 3 is detachably connected to the front side of the relay body 1, providing a user operation interface for directly configuring or controlling the settings of the relay.
[0030] A first rectangular opening 11 is provided on both sides of the left and right sides of the relay body 1, and a heat conducting plate 4 is provided in each of the two first rectangular openings 11. The heat conducting plate 4 helps to transfer the heat generated by the relay. A second rectangular opening 12 is provided on the top of the relay body 1, and a semiconductor cooling plate 5 is provided in the second rectangular opening 12. The cooling surface of the semiconductor cooling plate 5 is arranged toward the interior of the relay body 1, and is used to provide direct cooling when the relay is over-temperature. A temperature sensor 6 is provided at the bottom of the inner wall of the relay body 1. The temperature sensor 6 monitors the temperature inside the relay in real time and provides a data basis for temperature management. A monitoring controller 9 and a wireless communication module 14 are provided at the bottom of the relay body 1 and near the front side.
[0031] In this embodiment, a frame-shaped mounting plate 10 is provided on the front side of the relay body 1, and the operation panel 3 is detachably connected to the front side of the frame-shaped mounting plate 10 by bolts, so as to facilitate maintenance of the relay.
[0032] Specifically, the connection between the heat conducting plate 4 and the first rectangular opening 11 is sealed with adhesive, and the opposite sides of the two heat conducting plates 4 are provided with a plurality of heat dissipation fins 40 arranged equidistantly up and down, and the heat dissipation fins 40 enhance the heat dissipation efficiency.
[0033] Furthermore, a heat sink 8 is provided on the top of the relay body 1, and silicone grease is filled between the heat sink 8 and the heating surface of the semiconductor refrigeration plate 5 to help the heating surface of the semiconductor refrigeration plate 5 dissipate heat, create a heat pump effect, and improve cooling efficiency.
[0034] Furthermore, four connection columns 13 arranged in a matrix are provided on the rear side of the inner wall of the relay body 1 and near the top. The front sides of the four connection columns 13 are commonly connected to a small axial flow fan 7 to assist the semiconductor cooling plate 5 in air circulation and accelerate the cooling efficiency.
[0035] Furthermore, an audible and visual alarm 15 is provided at the bottom of the relay body 1 for issuing audible and visual warnings when the temperature is abnormal to quickly draw attention.
[0036] Furthermore, the semiconductor cooling sheet 5, the temperature sensor 6, the small axial flow fan 7, the wireless communication module 14 and the sound and light alarm 15 are electrically connected to the monitoring controller 9 through wires. The monitoring controller 9 serves as the "brain" of the system and is responsible for receiving data from the temperature sensor 6 and controlling the operation of the semiconductor cooling sheet 5, the small axial flow fan 7 and the sound and light alarm 15.

[0037] The temperature sensor 6 monitors the temperature inside the relay body 1 in real time. If an abnormal increase is detected, data is immediately sent to the monitoring controller 9. After receiving the high temperature signal, the monitoring controller 9 activates the semiconductor cooling plate 5 for cooling. At the same time, the monitoring controller 9 starts the small axial flow fan 7 to enhance the internal air circulation and improve the cooling efficiency. The wireless communication module 14 allows the monitoring device to communicate with an external management system or equipment to transmit real-time data or receive remote control instructions. Once the temperature is abnormal, the sound and light alarm 15 is activated at the same time, reminding the on-site personnel to take immediate action through sound and light.
[0038] When the relay working state monitoring device of this embodiment is in use, the built-in temperature sensor 6 will monitor the temperature inside the relay body 1 in real time. Once the temperature is found to be abnormally high, the temperature sensor 6 immediately sends alarm data to the monitoring controller 9. After receiving the high temperature signal, the monitoring controller 9 automatically starts the semiconductor refrigeration plate 5 and the small axial flow fan 7 to speed up the cooling process and improve the internal air circulation, thereby effectively preventing the relay from overheating and damage. At the same time, the design of the heat conducting plate 4 and the heat sink 8 ensures that the device can dissipate heat efficiently and operate reliably even under high load or harsh environment. The addition of the wireless communication module 14 provides the device with the ability of real-time data transmission and remote monitoring, allowing users to monitor the status of the device from a remote location and make necessary adjustments. Once the temperature abnormality is detected, the sound and light alarm 15 will be activated in time to remind the on-site personnel to take prompt measures through sound and light.
