Description

Technical Field

[0001] The present invention provides a bypass drainage device and a controller thereof, in particular, a low-voltage intelligent bypass device and an intelligent bypass controller thereof, belonging to the technical field of low-voltage power distribution operation and maintenance of power systems. Background Art

[0002] Low-voltage operation and maintenance refers to the process of daily maintenance, inspection and repair of electrical equipment with a voltage below 1000 volts. It is obviously an important link in the power system, because low-voltage equipment accounts for the vast majority of the power system. If a low-voltage device fails, it will directly affect the normal operation of the power system, and may even cause a power outage and affect the electrical equipment in production. Therefore, low-voltage operation and maintenance is crucial to the stability and safety of the power system.

[0003] At present, low-voltage operation and maintenance operations include the following operation procedures: 1. Power outage operation: Before performing low-voltage operation and maintenance operations, the power supply must be disconnected first to avoid electric shock accidents; at the same time, in order to ensure the safety of the operation, the operator needs to use an electrician to test the power to ensure that the power supply has been completely cut off; 2. Equipment inspection: After the power outage, the operator needs to conduct a detailed inspection of the electrical equipment, including inspections of appearance, smell, sound, etc. Through these inspections, it can be preliminarily determined whether the equipment has a fault; 3. Fault diagnosis: If there is a fault in the equipment, the operator needs to conduct further inspections and tests to determine the specific location and nature of the fault. During this process, the operator needs to strictly abide by the safety operating procedures to avoid accidents caused by improper operation; 4. Maintenance operation: After determining the location and nature of the fault, the operator needs to perform maintenance in accordance with the corresponding methods, and during the maintenance process, the operator needs to strictly abide by the safety operating procedures to ensure the quality and safety of the maintenance; 5. Acceptance and commissioning: After the maintenance is completed, the operator needs to inspect and commission the equipment to ensure the normal operation of the equipment. During this process, the operator needs to carefully check the various functions and parameters of the equipment to ensure that the equipment meets the use requirements; 6. Restoring power supply: After acceptance and commissioning, the operator needs to restore power to the equipment and pay close attention to the operation of the equipment to ensure normal operation of the equipment.

[0004] At present, when distribution operation and maintenance personnel work on 0.4kV lines, they often need to remove drainage and connect drainage. In practice, 0.4kV lines are often loaded. If they want to carry out the work, the entire substation needs to be shut down for cooperation. During the entire process of power outage, maintenance, and adjustment, not only the workload and working time of employees are increased, but also there are many related equipment involved, which increases the risk of employees getting into trouble. It is not in line with the concept of building a safe enterprise. At the same time, it also increases the power outage time of other users, which ultimately leads to a worse customer experience. In the current 0.4kV distribution line operation, due to the lack of suitable low-voltage bypass devices, operation and maintenance personnel must shut down the power when performing drainage or connecting drainage operations, which leads to complicated work processes, long working hours, and a wide range of power outages, which increases the risk of operations and affects the user's power experience. It is necessary to improve the existing technology. Summary of the invention
