As a professional manufacturer of durable electrical equipment with independent intellectual property rights, Kechang Electric has been dedicated to R&D and production of high-end power distribution equipment for 13 years. Its eco-friendly gas-insulated ring main unit is a flagship product with core competitiveness, and only a few domestic enterprises can produce such equipment. This article focuses on practical usage knowledge and common sense of this ring main unit, helping users better apply and maintain the equipment in actual work.
1. Core Advantages and Applicable Scenarios
Different from traditional ring main units, Kechang Electric's eco-friendly gas-insulated ring main unit adopts environment-friendly insulating gas and advanced structural design, which has obvious advantages in safety, energy conservation and miniaturization. Its core advantages mainly include three aspects: first, the eco-friendly insulating gas replaces traditional SF6 gas, realizing zero pollution to the environment; second, the overall structure is compact, which can save more installation space compared with conventional products; third, it has excellent insulation performance and arc-extinguishing capacity, ensuring stable operation in complex power distribution environments.
In terms of applicable scenarios, this ring main unit is widely used in urban power distribution networks, industrial parks, commercial complexes, new energy power stations and other fields. It is especially suitable for areas with high environmental protection requirements, limited installation space or harsh operating conditions, such as downtown areas with dense buildings, coastal areas with high humidity and salt spray, and industrial zones with more dust. It can effectively realize the functions of power distribution, protection and control in the power grid, and ensure the safe and stable supply of electricity.
2. Key Precautions for Installation
The installation quality of the eco-friendly gas-insulated ring main unit directly affects its operation stability and service life. The following key points must be strictly followed during installation:
First, the installation site must meet the environmental requirements. The ambient temperature should be between -25℃ and 40℃, and the relative humidity should not exceed 85% (without condensation). The site should be dry, well-ventilated, free from flammable and explosive substances, and far away from strong magnetic field interference sources to avoid affecting the insulation performance and control system of the equipment.
Second, the hoisting and transportation must be standardized. The ring main unit is a precision electrical equipment, so it is necessary to use professional hoisting tools during transportation and installation, and the hoisting point must be consistent with the position marked on the equipment to prevent deformation or damage to internal components. During transportation, avoid severe vibration and collision, and fix the equipment firmly to ensure its integrity.
Third, the wiring operation must comply with specifications. Before wiring, confirm the phase sequence, voltage level and current rating of the equipment to ensure that it matches the power grid parameters. The connection of cables and busbars must be firm, and the torque of fasteners should meet the technical requirements to prevent poor contact caused by loose wiring, which may lead to overheating or equipment failure. After wiring, check the insulation resistance of the circuit to ensure that there is no leakage or short circuit.
3. Common Misunderstandings in Daily Use
In the process of using the eco-friendly gas-insulated ring main unit, many users have misunderstandings due to insufficient understanding of the product, which may affect the normal operation of the equipment. Here are the most common misunderstandings to clarify:
Misunderstanding 1: No need to check the gas pressure after installation. Although the equipment adopts sealed gas insulation design, it is still necessary to regularly check the gas pressure. If the gas pressure is too low, it will reduce the insulation performance and arc-extinguishing capacity of the equipment, and even cause equipment damage. It is recommended to check the gas pressure once a month and record the data.
Misunderstanding 2: The equipment can be disassembled at will when there is a fault. The internal structure of the eco-friendly gas-insulated ring main unit is complex, and it involves professional technologies such as gas insulation and intelligent control. If a fault occurs, do not disassemble the equipment without permission, otherwise it may lead to gas leakage, component damage or safety accidents. It is necessary to contact Kechang Electric's professional after-sales personnel for maintenance.
Misunderstanding 3: The eco-friendly gas can be replaced with other gases at will. The insulating gas used in the equipment is specially configured for its structure and performance, which has excellent insulation and environmental protection performance. It is strictly prohibited to replace it with other gases without permission, otherwise it will not only affect the operation effect of the equipment, but also may cause environmental pollution.
4. Daily Maintenance and Fault Handling
Scientific daily maintenance can effectively extend the service life of the eco-friendly gas-insulated ring main unit and reduce the occurrence of faults. The following maintenance tips and fault handling methods are for reference:
In terms of daily maintenance, first, carry out regular visual inspection. Check the appearance of the equipment for damage, deformation, corrosion or gas leakage. Observe the indicator lights and display screen of the control panel to confirm that the equipment is in normal operation state. Second, clean the equipment regularly. Use a dry and clean cloth to wipe the surface of the equipment and the control panel to remove dust and dirt, and avoid using corrosive cleaning agents to prevent damage to the equipment shell and components. Third, carry out a comprehensive inspection every six months, including checking the gas pressure, insulation resistance, operation status of the circuit breaker and the reliability of the control system.
In terms of fault handling, if the equipment alarms, first judge the fault type according to the alarm information on the control panel. If it is a gas pressure low alarm, check whether there is gas leakage. If there is no obvious leakage, you can contact the after-sales personnel to supplement the gas; if there is leakage, immediately cut off the power supply and arrange professional personnel to repair it. If it is an overcurrent or overvoltage alarm, check whether the load of the power grid exceeds the rated capacity of the equipment, and adjust the load distribution in time to ensure that the equipment operates within the rated parameters.
5. Important Safety Reminders
The eco-friendly gas-insulated ring main unit is a high-voltage electrical equipment, so safety must be put in the first place during use and maintenance:
First, operators must hold relevant electrical operation certificates and strictly abide by electrical safety operation specifications. Do not touch the live parts of the equipment during operation, and do not carry out maintenance or inspection work with electricity. Before operation, it is necessary to implement the power failure, power inspection, grounding and listing procedures to ensure the safety of operators.
Second, when handling gas leakage, wear professional protective equipment (such as gas masks and gloves), and ventilate the site in time to prevent gas poisoning or environmental pollution. The leaked gas must be treated in accordance with environmental protection requirements and shall not be discharged at will.
Third, do not modify the internal structure, electrical circuit or control parameters of the equipment without permission. Any modification will affect the performance and safety of the equipment, and may lead to equipment failure or safety accidents. If it is necessary to adjust the parameters, it must be operated by professional personnel of Kechang Electric.
In summary, Kechang Electric's eco-friendly gas-insulated ring main unit is a high-performance, environmentally friendly and safe power distribution equipment. Correct installation, standardized use and regular maintenance can not only give full play to its core advantages, but also ensure long-term stable operation.
