Test objects:

Vacuum degree test: Measure the vacuum degree of the equipment during the operation process to ensure that the equipment reaches the preset vacuum degree index and meets the process requirements.

Pressure test: Check whether the pressure of the equipment during the oil filling process is stable to prevent adverse effects on the transformer due to excessive or insufficient pressure.

Oil quality test: Detect whether the oil injected into the transformer is pure, and whether there are any adverse components such as impurities and moisture to ensure that the quality of the oil meets the standard.

Temperature test: Monitor the temperature during the operation of the equipment to prevent the performance and safety of the equipment from being affected due to too high or too low temperature.

Electrical performance test: Detect the electrical performance of the equipment, such as insulation resistance, voltage withstand test, etc., to ensure the electrical safety and reliability of the equipment.

Flow rate test: Measure the flow rate of the equipment during the oil filling process to ensure that the amount of oil injected meets the requirements.

Control system test: Check whether the control system of the equipment works normally, such as control logic, sensors, etc., to ensure that the equipment can perform automatic control according to the preset program.

Appearance quality test: Check the appearance quality of the equipment to ensure that there are no obvious defects, damages, and deformations.

Environment adaptability test: Simulate the conditions of the equipment in the actual operating environment, such as temperature, humidity, vibration, etc., to conduct tests on the equipment to ensure its adaptability and reliability.

Detection items:

Electrical strength: This is an important index to measure the insulating performance of transformer oil, and its insulating performance can be evaluated by measuring the electrical strength to see if it meets the standard.

Water content: Detect the water content in the transformer oil to ensure that the water content is within the specified range to prevent equipment failure due to excessive water content.

Dissolved gas chromatographic analysis: Conduct chromatographic analysis on the dissolved gas in the transformer oil to detect whether there are abnormal gases in the oil and the content of the gas, which helps to discover potential problems inside the equipment in a timely manner.

Appearance and structure inspection: Inspect the appearance and structure of the equipment, including the integrity of the equipment, whether there is damage or corrosion, and the installation and connection of each component.

Performance test: Test the various performance indicators of the equipment, such as vacuum degree, oil filling speed, and oil filling amount, to ensure that the equipment performance meets the requirements.

Safety performance test: Test the safety performance of the equipment, such as overload protection, oil overflow protection, etc., to ensure the safety of the equipment during use.

Environmental performance test: Test the environmental performance of the equipment, such as noise, exhaust gas, and wastewater discharge, to ensure that the equipment meets environmental protection standards.
