箱式变电站停送电操作流程The operational flow for stopping and resuming power supply in a box-type substation involves several key steps. Initially, it is crucial to ensure that all personnel involved in the operation are properly trained and qualified. Safety equipment such as gloves, helmets, and insulated boots must be worn to minimize the risk of accidents.Before stopping the power supply, it is essential to notify all relevant personnel and departments to ensure that they are aware of the impending operation and can take necessary precautions. Additionally, it is important to inspect the substation equipment for any abnormalities or potential hazards.During the power supply stopping process, the main switchgear should be operated first. This involves opening the circuit breakers and disconnecting the transformers to isolate the substation from the power grid. It is crucial to follow the specified operating procedures to ensure safety and prevent damage to the equipment.After the power supply has been stopped, it is necessary to conduct a thorough inspection of the substation to ensure that all power sources have been effectively isolated. This includes checking for residual voltages and verifying the isolation status of all relevant equipment.When resuming the power supply, the same safety precautions and operating procedures must be followed. The transformers and circuit breakers should be reconnected in the reverse order of the stopping process. It is important to monitor the equipment's operational status and ensure that there are no abnormalities or issues during the resumption.Finally, once the power supply has been fully resumed, a final inspection should be conducted to verify that all equipment is operating normally and that there are no remaining hazards. All personnel involved in the operation should also be debriefed on the process and any observed issues or concerns.箱式变电站的停送电操作流程涉及几个关键步骤。

箱式变电站停送电操作流程英文回答:Box-type substation is an important component of the power distribution system. It is responsible for transforming high voltage electricity from the transmission system into low voltage electricity for local consumption. The operation of stopping and restoring power in a box-type substation involves several steps. Let me explain the process in detail.Firstly, before initiating any operation, it is crucial to ensure the safety of the personnel involved. This includes wearing appropriate personal protective equipment (PPE) such as gloves, safety glasses, and helmets. It is also important to isolate the substation from the power supply by opening the circuit breaker and locking it in the open position.Next, the power supply to the substation needs to bedisconnected. This can be done by switching off the main switch or disconnecting the power cables from the incoming supply. It is important to follow the correct proceduresand ensure that all power sources are properly isolated to avoid any accidents.Once the power supply is disconnected, it is necessaryto check the status of the equipment inside the substation. This includes inspecting the circuit breakers, transformers, and other components for any signs of damage or malfunction. Any issues should be reported and resolved beforeproceeding with the operation.After ensuring the equipment is in good condition, the next step is to perform the necessary maintenance or repairs. This may involve replacing faulty components, cleaning or lubricating moving parts, or conducting routine inspections. It is important to follow the manufacturer's instructions and industry best practices during this process.Once the maintenance or repairs are completed, thepower can be restored to the substation. This involves reversing the steps taken to disconnect the power supply. The main switch can be turned on or the power cables can be reconnected, depending on the specific configuration of the substation. It is essential to follow the correct sequence and ensure that all connections are secure.Finally, after restoring power, it is important to test the substation to ensure everything is functioning properly. This may involve conducting voltage and current measurements, checking for any abnormal readings, and verifying the proper operation of all equipment. Any issues should be addressed before the substation is put back into service.中文回答:箱式变电站是电力配电系统的重要组成部分。

箱式变电站停送电操作流程英文回答:The process of shutting down and restoring power in a pad-mounted substation, also known as a box-type substation, involves several steps to ensure safety and proper operation. Here is a general outline of the operating procedure:1. Preparation: Before initiating any power shutdown,it is essential to ensure that all necessary safety measures are in place. This includes wearing appropriate personal protective equipment (PPE) such as gloves, safety glasses, and flame-resistant clothing. Additionally, the operator must have a clear understanding of the equipment and its operating procedures.2. Communication: Effective communication is crucial during the shutdown process. The operator should inform all relevant parties, including other operators, maintenancepersonnel, and customers, about the upcoming power interruption. This can be done through various means suchas phone calls, emails, or in-person meetings.3. Isolation: The next step is to isolate thesubstation from the power grid. This involves opening the main circuit breaker or switches to disconnect the substation from the upstream power source. It is importantto verify that all disconnecting devices are in the open position and properly locked out to prevent accidental re-energization.4. Load Shedding: If necessary, load shedding may be performed to reduce the power demand on the substation.This can be achieved by selectively opening feeder breakers or switches to disconnect certain loads from the substation. Load shedding helps prevent overloading and ensures a smooth transition during the shutdown and restoration process.5. De-energization: After isolating the substation and shedding the load, the operator can proceed with de-energizing the equipment within the substation. This may involve opening additional circuit breakers or switches to de-energize specific equipment such as transformers, switchgear, or control panels. It is crucial to follow proper procedures and safety guidelines to avoid electrical hazards.6. Visual Inspection: Once the substation is de-energized, the operator should visually inspect the equipment for any signs of damage or abnormal conditions. This includes checking for loose connections, overheating, or any physical damage that could pose a safety risk. If any issues are identified, appropriate actions should be taken to rectify them before restoring power.7. Maintenance and Repairs: During the power interruption, maintenance or repair work can be performed on the substation equipment. This may involve replacing faulty components, conducting routine inspections, or addressing any identified issues. It is important to follow proper maintenance procedures and ensure that all work is carried out safely and efficiently.8. Power Restoration: Once all necessary maintenance and repairs are completed, the operator can proceed with restoring power to the substation. This involves reversing the steps taken during the shutdown process. The operator should close the circuit breakers or switches, re-energize the equipment, and gradually reconnect the substation to the power grid. This ensures a smooth and controlled restoration of power without causing any sudden surges or disruptions.中文回答:箱式变电站的停送电操作流程涉及多个步骤,以确保安全和正常运行。
一、变压器停、送电操作的顺序:
停电时先停负荷侧:《开关箱→分配电箱→配电屏(总配电箱)》,后停电源侧。
送电时先送电源侧:《配电屏(总配电箱)→分配电箱→开关箱》,再送负荷侧。
(1)从电源侧向负荷侧送电,如有故障,便于确定故障范围,及时作出判断和处理,以免故障蔓延扩大;
(2)多电源的情况下,先停负荷可以防止变压器反充电,若先停电源侧,遇有故障可能造成保护装置误动或拒动,延长故障切除时间,并可能扩大故障范围;
(3)当负荷侧母线电压互感器带有低频减负荷装置,而未装电流闭锁时,一旦先停电源侧开关,由于大型同步电机的反馈,可能使低频减负荷装置误动。
二、优点:
这种操作顺序的优点是:送电时,除开关箱中的控制开关以外,其余配电装置中的开关电器均是空载会闭.不会产生危害操作者和开关电器的电弧或电火花;停电时,只要开关箱中的控制开关分闸,其余配电装置中的开关电器都是空载分闸,也不会产生危害操作者和开关电器的电弧或电火花。
如果倒置操作,则当送电时,配电屏或总配电箱中的开关电器将带大负荷合闸,会产生强大电弧,尤其当最后合闸的是电源隔离开关时,对操作者的隔离开关的危害更大,这是不允许的,同时,远离配电屏或总配电箱的用电设备突然起动,也会给其周围的操作者和作业人员带来意外伤害。
停电时,也有类似的危害,一方面配电屏或总配电箱中的开关电器,尤其是电源隔离开关带强大负荷分闸,会产生强烈电弧或电火花,会对操作者和开关电器带来危害,另一方面,全现场突然停电也不容易与所有用电设备操作者的停电准备达成一致。
