2024年无人值班水电厂消防系统的自动化管随着科技的进步和智能化的发展，无人值班水电厂消防系统的自动化管理已成为现实。

在2024年的水电厂中，消防系统将通过自动化管理实现更高效、更安全的运行。

本文将探讨无人值班水电厂消防系统自动化管理的各个方面，并提出一些解决方案。

首先，无人值班水电厂消防系统的自动化管理将基于先进的传感器技术。

传感器将安装在各个关键位置，监测火灾、漏水等安全风险。

当传感器检测到异常情况时，系统将立即发出警报并采取相应的紧急措施。

例如，当传感器检测到火灾时，系统将立即触发自动喷水系统，并通知相关人员前往处理。

其次，无人值班水电厂消防系统的自动化管理将借助于人工智能和大数据分析技术。

通过分析历史数据和实时监测数据，系统能够预测潜在的安全风险，并采取相应的措施进行预防。

同时，人工智能还能够学习和优化消防系统的运行策略，提高系统的自适应能力和反应速度。

第三，无人值班水电厂消防系统的自动化管理还将实现与其他设备和系统的智能互联。

例如，与水厂的供水系统、电厂的供电系统等相互连接，实现资源的共享和协同工作。

当传感器发现火灾或漏水时，系统将自动停止供电和供水，避免事态的扩大。

同时，消防系统还可以通过与安防监控系统的联动，快速定位事发地点并通知相关人员前往处置。

第四，无人值班水电厂消防系统的自动化管理还将实现远程监控和控制。

通过互联网和远程通信技术，管理人员可以随时随地监控水电厂的消防系统，并对系统进行远程操作和控制。

这不仅提高了效率，还能够有效地节约人力成本和资源。

然而，实现无人值班水电厂消防系统的自动化管理也面临一些挑战。

首先，技术的成本和复杂性是一个主要的问题。

为了实现自动化管理，需要投入大量的资金和人力来安装和维护各种设备和系统。

此外，技术的复杂性也需要专业的人员进行管理和操作，需要加强培训和人才引进。

其次，网络安全是一个重要的考虑因素。

无人值班水电厂消防系统的自动化管理需要与互联网相连接，这也给系统带来了网络攻击和数据泄露的风险。

For SKD32.. and SKD82.. the Y1 signal must be routed via an additional freely-adjustable end switch (ASC9.3) to limit the stroke.We recommend that you contact your local Siemens office for the necessary information.Overview table, see page 20.Technology1 Manual adjuster2 Pressure cylinder3 Suction chamber4 Return spring5 Solenoid valve6 Hydraulic pump7 Piston8 Pressure chamber 9 Position indicator (0 to 1) 10 Coupling 11 Valve stem 12 Plug Valve closed Valve openNoteRev. no. Principle ofelectro-hydraulic actuators4/20The hydraulic pump (6) forces oil from the suction chamber (3) to the pressure chamber (8) and thereby moving the pressure cylinder (2) downwards. The valve stem (11) retracts and the valve opens. Simultaneously the return spring (4) is compressed. Activating the solenoid valve (5) allows the oil in the pressure chamber to flow back into the suction chamber. The compressed return spring moves the pressure cylinder upwards. The valve stem extends and the valve closesTurning the manual adjuster (1) clockwise moves the pressure cylinder downwards and opens the valve. Simultaneously the return spring is compressed.In the manual operation mode the control signals Y and Z can further open the valve but cannot move to the «0%» stroke position of the valve. To retain the manually set position, switch off the power supply or disconnect the control signals Y and Z. The red indicator marked «MAN» is visible.When setting the controller for a longer time period to manual operation, werecommend adjusting the actuator with the manual adjuster to the desired position. This guarantees that the actuator remains in this position for that time period. Attention: Do not forget to switch back to automatic operation after the controller is set back to automatic control.Turn the manual adjuster counterclockwise to the end stop. The pressure cylinder moves upward to the «0%» stroke position of the valve. The red indicator marked «MAN» is no longer visible.The actuator can manually be adjusted to a stroke position > 0 % allowing its use in applications requiring constantly a minimal volumetric flow.The SKD32.51, SKD32.21, SKD82.51.. and SKD62.. actuators, which feature a spring-return function, incorporate a solenoid valve which opens if the control signal or power fails. The return spring causes the actuator to move to the «0 %» stroke position and closes the valve.The actuator is controlled by a 3-position signal either via terminals Y1 or Y2 and generates the desired stroke by means of above described principle of operation. • Voltage on Y1 piston extends valve opens • Voltage on Y2 piston retracts valve closes • No voltage on Y1 and Y2 piston / valve stem remain in the respective positionThe valve is either controlled via terminal Y or override control Z. The positioning signal Y generates the desired stroke by means of above described principle of operation. • Signal Y increasing: piston extends valve opens • Signal Y decreasing: piston retracts valve closes • Signal Y constant: piston / valve stem remain in the respective position • Override control Z see description of override control input, page 8A frost protection thermostat can be connected to the SKD6.. actuator. The added signals from the QAF21.. and QAF61.. require the use of SKD62UA actuators.

Failure to comply may cause the safety limiter function to fail.For media below 0 °C the ASZ6.6 stem heater is required to keep the valve from freezing. For safety reasons the stem heater is designed for an operating voltage of AC 24 V / 30 W.For this case, do not insulate the actuator bracket and the valve stem, as air circulation must be ensured. Do not touch the hot parts without prior protective measures to avoid burns.Non-observance of the above may result in accidentsand fires!Recommendation: Above 140 °C insulating the valves is strictly recommended.Observe admissible temperatures, refer to «Use» on page 2 and «Technical data» on page 13.If an auxiliary switch is required, its switching point should be indicated on the plant schematic.Every actuator must be driven by a dedicated controller (refer to«Connection diagrams», page 16).11/20Mounting instructionsMounting Instruction 74 319 0325 0 for fitting the actuator to the valve are by packed in the actuator packaging. The instructions for accessories are enclosed with the accessories themselves.Commissioning notesWhen commissioning the system, check the wiring and functions, and set any auxiliary switches and potentiometers as necessary, or check the existing settings. Coupling fully retracted→stroke = 0%Coupling fully extended→ stroke = 100 %The manual adjuster must be rotated counterclockwise to the end stop, i.e. until the red indicator marked «MAN» is no longer visible. This causes the Siemens valves, types VVF.., VVG.., VXF.. and VXG.. to close (stroke = 0%).Manual operation «M A N»Automatic operation« A U T O »Orientation12/20Maintenance notesThe SKD.. actuators are maintenance-free.When servicing the actuator:• Switch off pump of the hydronic loop• Interrupt the power supply to the actuator • Close the main shutoff valves in the system• Release pressure in the pipes and allow them to cool down completely • If necessary, disconnect electrical connections from the terminals• The actuator must be correctly fitted to the valve before recommissioning. Recommendation SKD6..: trigger stroke calibration.«Replacement parts», see page 19.A damaged housing or cover represents an injury risk• NEVER uninstall an actuator from the valve• Uninstall the valve-actuator combination (actuating device) as a complete device• Use only properly trained technicians to uninstall the unit• Send the actuating device together with an error report to your local Siemens representative for analysis and disposal• Properly mount the new actuating device (valve and actuator)Parts could fly ultimately resulting in injuries from uninstalling an actuator with a damaged valve housing due to the tensioned return spring.DisposalWarrantyTechnical data on specific applications are valid only together with Siemens products listed under "Equipment combinations", page 3.
