Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, specifically to an integrated cabinet structure for steam turbine control, monitoring and protection. Background Technology

[0002] A server rack is a cabinet used to store computers and related information and data control equipment. It can protect the stored equipment by shielding it from electromagnetic interference and solve the problems of high-density heat dissipation of internal equipment components, cable routing and management, large-capacity and stable power distribution, and full compatibility with rack-mounted equipment from different manufacturers. This meets the needs of fast, efficient, and low-cost communication operations and solves the needs of network deployment.

[0003] System integration typically refers to the business of combining software, hardware, and communication technologies to solve information processing problems for users. The various separate parts of the integration were originally independent systems. The integrated whole can work together organically and in coordination to achieve overall benefits and optimization. In the process of system integration, electrical equipment needs to be placed in cabinets.

[0004] Speed ​​control, condition monitoring, and safety systems for small steam turbines are crucial for ensuring their safe and efficient operation. With technological advancements and increased specialization, the standardized and modular integrated design of these systems is becoming increasingly important. This not only helps improve system reliability and significantly shortens on-site turbine commissioning time, but also simplifies daily maintenance for users, thereby effectively reducing the overall project cost. Summary of the Invention

[0005] This invention primarily addresses the shortcomings of existing technologies by providing an integrated cabinet structure for steam turbine control, monitoring, and protection. This structure is compact, fully functional, easy to operate, and exhibits good operational stability. By applying the design concepts of integration, standardization, and modularity to the speed control and monitoring and safety system of small steam turbines, it not only improves the overall performance of the system but also significantly enhances its reliability and ease of maintenance.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0007] An integrated cabinet structure for turbine control, monitoring and protection includes a control and monitoring cabinet. The control and monitoring cabinet is equipped with a status monitor, a speed governor, a three-out-of-two trip protector and a status monitoring display at the front, and relays and terminal blocks at the rear. The relays and terminal blocks are used to connect the status monitor, speed governor, three-out-of-two trip protector and status monitoring display to the circuit.

[0008] The governor is one of the most important control devices in a steam turbine generator set. Its operational quality directly determines the safe and stable operation of the unit. Reducing the failure rate of the turbine governor is the most effective way to improve the reliability of the unit's operation.

[0009] The "two-out-of-three" principle in a 3-out-of-two trip protection device means that at least two out of three identical or similar conditions must be met to trigger a certain action. Using this logic effectively avoids malfunctions that might result from a single detection signal. By employing the "two-out-of-three" method, tripping is only triggered when at least two signals simultaneously confirm a fault, thus significantly improving the accuracy of the protection action.

[0010] Preferably, the control and monitoring cabinet has a rear door at the rear end, with several ventilation filters on the outside of the rear door and several fans connected to the ventilation filters on the inside of the rear door.

[0011] Preferably, the upper side of the control and monitoring cabinet is equipped with a temperature controller connected to the fan circuit.

[0012] Preferably, a door handle is provided in the middle of one side of the rear cabinet door.

[0013] Preferably, the control and monitoring cabinet has a front door frame at the front end, a viewing glass inside the front door frame, and a sealing ring between the viewing glass and the front door frame.

[0014] Preferably, a door handle is provided in the middle of one side of the front door frame.

[0015] Preferably, the control and monitoring cabinet is provided with a base at its lower end.

[0016] Preferably, the control and monitoring cabinet is equipped with a light at the top front end.

[0017] Preferably, the control and monitoring cabinet is equipped with lifting rings at all four corners of its upper end.

[0018] This invention can achieve the following effects:

[0019] This invention provides an integrated cabinet structure for steam turbine control, monitoring, and protection. Compared with existing technologies, it features a compact structure, comprehensive functions, convenient operation, and good operational stability. By applying the design concepts of integration, standardization, and modularity to the speed control and monitoring and safety system of small steam turbines, it not only improves the overall performance of the system but also significantly enhances its reliability and ease of maintenance.

[0020] Integration refers to combining the speed control system, condition monitoring system, and safety system of a small steam turbine into a complete unified system. This integration approach enables more efficient control, monitoring, and protection, while also better coordinating the operation of the various subsystems.

[0021] Standardization refers to the adoption of unified standards in the design and manufacturing process. For small steam turbines and their control systems, this means using common interfaces, protocols, and components. The advantages of standardization are improved compatibility between equipment, facilitating the interoperability of products from different manufacturers, and also simplifying the procurement and replacement of spare parts.

[0022] Modular design allows the system to consist of multiple independent but interchangeable modules. Each module is responsible for a specific function or task, such as speed control or vibration monitoring. This design makes the system more flexible, allowing for quick configuration adjustments to meet specific needs, and also facilitates maintenance and upgrades.

[0023] Server racks are typically used to house and protect the electronic equipment in all the control systems and monitoring and security systems mentioned above. A suitable server rack must not only provide sufficient space to install all the necessary hardware, but also take into account factors such as heat dissipation and protection levels (e.g., waterproofing and dustproofing) to ensure that the system can operate stably in various environments.
