[0002] In electrified railways, there are numerous contact wire disconnect switches with a wide distribution range. Contact wire disconnect switches are one of the important pieces of equipment in the electrified railway traction power supply system. They are mainly used for contact wire fault isolation, section power outage maintenance, section power outage operations, and changing power supply operation modes. Therefore, the contact wire electric disconnect switch control device is an important piece of equipment in the railway traction power supply system.

[0003] Traditional direct-control contact network electric disconnector control devices are complex in function and contain a variety of components. The large number of components and complex internal structure of the control cabinet result in low heat dissipation efficiency and high temperature, which can easily lead to failure and potential safety hazards. Therefore, a contact network disconnector monitoring device is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problems of messy layout, low heat dissipation efficiency, and potential safety hazards in the existing technology, and to propose a monitoring device for contact network disconnect switches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A monitoring device for a contact network disconnector includes a cabinet, a front glass door and a rear double door hinged to the front and rear sides of the cabinet. Inside the cabinet, from top to bottom, are respectively arranged an upper-level AC device, a middle-level DC device, and a lower-level wiring device that are electrically connected to each other. A cabinet frame is fixedly connected to the inner wall of the cabinet. A heat dissipation module is fixedly installed on the top of the cabinet frame. The upper-level AC device is fixedly connected to the upper part of the cabinet frame and is located next to the heat dissipation module. The middle-level DC device is fixedly connected to the middle part of the cabinet frame, and the lower-level wiring device is fixedly connected to the lower part of the cabinet frame. The upper-level AC device, middle-level DC device, and lower-level wiring device are arranged in a functional modular layer.

[0007] Preferably, the upper-level AC equipment includes interconnected indicator lights, a communication management unit, an AC circuit breaker, a rectifier module, a dual power conversion device, and a switching power supply;

[0008] The intermediate-level DC equipment includes a centralized monitoring unit, a knob module, a DC circuit breaker, a power module, a switch, and a monitoring unit that are electrically connected to each other.

[0009] The lower-level wiring device includes multiple horizontally distributed terminal blocks;

[0010] A mounting plate is fixedly connected to the front side of the cabinet frame, and the indicator lights, centralized monitoring unit, knob module, and DC circuit breaker are fixedly installed on the front side of the mounting plate from top to bottom.

[0011] Preferably, the cabinet frame is made of aluminum alloy to ensure the cabinet's sturdiness and durability.

[0012] Preferably, the front glass door is made of double-layered tempered glass.

[0013] Preferably, the rear double doors are made of metal, and a sealing strip is provided between the rear double doors and the cabinet body.

[0014] Preferably, the terminal blocks adopt a modular design, with each terminal block having an independent fixing bracket.

[0015] Preferably, a safety distance of more than 10cm is reserved between the upper-layer AC equipment, the middle-layer DC equipment, and the lower-layer wiring equipment.

[0016] Compared with the prior art, this utility model provides a monitoring device for contact wire disconnect switches, which has the following advantages:

[0017] 1. This utility model's monitoring device is designed with three main functional layers: an upper layer of AC equipment, a middle layer of DC equipment, and a lower layer of wiring equipment. Each functional layer is laid out according to its specific functional requirements, ensuring the functionality and ease of operation of the equipment. The heat dissipation module is fixedly installed on the top of the cabinet frame, close to the upper layer of AC equipment. Since AC equipment usually generates a lot of heat, the heat dissipation module can effectively provide heat dissipation support for the upper layer of AC equipment. The heat dissipation module helps to ensure that heat can be dissipated quickly and prevent the equipment from overheating. By arranging different functional equipment in layers and leaving sufficient safety distance, electrical interference between equipment and potential failure risks can be significantly reduced. The lower layer mainly contains wiring equipment such as terminal blocks, which facilitates wiring and reduces potential short circuit and fire risks, thereby improving the overall reliability of the equipment. In summary, this device is set up in layers according to the functional modularity of each component. Through reasonable component layout and layer design, heat dissipation efficiency is improved, and safety hazards caused by messy wiring and mutual interference between equipment are effectively reduced.

[0018] 2. This utility model achieves clear division and efficient integration of functional modules by layering upper-level AC equipment, middle-level DC equipment, and lower-level wiring equipment. The interconnection of upper-level AC equipment such as indicator lights, communication management units, and AC circuit breakers ensures stable transmission and real-time monitoring of AC signals. The electrical connections of the middle-level DC equipment, including the centralized monitoring unit, knob modules, and DC circuit breakers, enhance the convenience and reliability of DC power management. The modular terminal block design of the lower-level wiring equipment simplifies wiring operations and improves maintenance efficiency. The aluminum alloy provides higher strength and lighter weight, significantly improving the cabinet's structural integrity. The robustness and durability extend the service life of the device. The double-layered tempered glass provides excellent visibility, allowing maintenance personnel to observe the status of internal components in real time, promptly detect and handle faults, and ensure the cabinet's sealing and dustproof performance. This effectively prevents external factors such as dust and moisture from corroding the internal equipment, ensuring stable operation of the device in harsh environments. Each terminal block has an independent fixed bracket, facilitating ventilation, heat dissipation, and installation / removal, improving the device's heat dissipation efficiency, extending the equipment's service life, effectively avoiding mutual interference between devices of different voltage levels, reducing the probability of electrical faults, and enhancing the device's safety performance.
