Publish Time: 2024-07-02
The insulation performance of High Voltage Centrally Installed Switchgear is the key factor to ensure its safe and stable operation. In order to ensure the insulation performance of High Voltage Centrally Installed Switchgear, the following aspects can be taken into consideration:
1. Material selection and insulation design
Insulation materials: Select materials with good insulation performance, such as epoxy resin, plastic, rubber, etc. with new formulas. These materials can effectively prevent current leakage and improve the insulation strength of the equipment.
Insulation design: Combine the composite (combined) design of components and the centralized assembly of components to design a suitable insulation scheme. For example, in the KYN cabinet, the combined structure of the transformer bushing contact box and insulator is reasonably designed to ensure the required insulation coordination.
2. Manufacturing process and quality control
Improving formula and process: During the manufacturing process, continuously improve the formula and manufacturing process of insulation materials to ensure the stable and reliable quality of insulation parts. Avoid using metal materials as components such as movable baffles to prevent electrical insulation from being affected in the event of jamming.
Strict quality control: Manufacturers should strictly follow national standards to ensure the manufacturing quality requirements and assembly process requirements of supporting accessories. Insulation parts should be strictly inspected and tested to ensure that they meet the insulation performance requirements.
3. Environmental control and protective measures
Environmental control: In order to reduce the impact of the external environment on the insulation performance of high-voltage switchgear, it is necessary to ensure good ventilation in the switch room and strictly control the amount of dust, humidity and temperature. Avoid high temperature, high humidity and other harsh environments from damaging the insulation materials.
Protective measures: Take necessary protective measures, such as installing dust covers and moisture-proof mats, to prevent dust, moisture, etc. from entering the equipment and affecting the insulation performance. At the same time, prevent small animals from entering and causing damage to electrical equipment.
4. Maintenance inspection and real-time monitoring
Regular maintenance: Strengthen the maintenance of high-voltage switchgear and clean the dust on the insulation layer in time. When the insulation layer is found to be damaged, remedial measures should be taken in time. Regularly test the insulation performance of the high-voltage switchgear to ensure that it is in good condition.
Real-time monitoring: Use real-time online monitoring technology, such as an automated monitoring system based on ultrasonic detection technology and TEV detection technology, to monitor the insulation performance of the high-voltage switchgear in real time. Once the insulation performance is degraded or abnormal conditions are found, take measures to deal with it immediately.
5. Other measures
Spatial spacing adjustment: By adjusting the spatial spacing inside the switchgear, the spatial spacing range is increased to prevent leakage problems, thereby effectively improving the overall environmental level.
Overvoltage protection: Adopt reasonable protection measures, such as installing zinc oxide lightning arresters and other equipment to protect overvoltage and prevent overvoltage from damaging insulation performance.
To ensure the insulation performance of High Voltage Centrally Installed Switchgear, it is necessary to start from multiple aspects such as material selection, manufacturing process, environmental control, maintenance detection and real-time monitoring. Through comprehensive measures and scientific management, the insulation performance of High Voltage Centrally Installed Switchgear can be ensured to be stable and reliable, providing strong guarantee for the safe and stable operation of the power system.
