In the electrical system, different equipment and areas may have different power demands, and Switchgear equipment can automatically adjust the distribution of current according to the real-time load conditions of the system to ensure that each part works under the appropriate load, thereby improving the efficiency of the entire system.
Switchgear equipment is a key device in the power system, used to control, protect and isolate electrical equipment. In critical situations, the switchgear plays a vital role, and the activation of its emergency shutdown program is a key measure to protect the stability of the system and effectively prevent accidents. Emergency shutdown procedures are typically designed to interrupt system operations quickly and accurately to minimize potential damage and danger.
How to test Switchgear equipment:
Electrical parameter test:
Use accurate measuring equipment to test electrical parameters such as current, voltage, frequency, etc.
Check the connection points to make sure the electrical connection is reliable and there is no overheating.
Protection device testing:
Simulate power failure scenarios to ensure that protection devices can quickly and reliably cut off circuits.
Conduct regular tests on different types of protection devices, including overcurrent protection, overvoltage protection, etc.
Function test:
Carry out functional tests of the Switchgear equipment in different operating modes, including manual and automatic operation.
Confirm that the switch operates normally, including the opening and closing of the switch, and the operation of the isolation switch.
Insulation test:
Use an insulation resistance tester to check the insulation performance of Switchgear equipment and make sure the insulation resistance is within the normal range.
Check insulation materials regularly to prevent deterioration or damage.
Environmental awareness test:
Tested under conditions that simulate actual working environments, including extreme temperatures, humidity and short-circuit testing.
Make sure the switch cabinet can operate stably under various environmental conditions.
Mechanical performance test:
Check the mechanical components to ensure that switches, isolating switches, etc. can operate normally without jamming or abnormal noise.
Regularly lubricate mechanical connecting parts to ensure flexibility and reliability.
Adjust the test equipment:
Arrange testing instruments regularly to ensure the accuracy and reliability of test results.
Use adapted instruments to carry out various tests on switchgear equipment.
How to maintain switch cabinet equipment:
Regular inspection and cleaning:
Appearance inspection to ensure it is in good condition and the logo is clear and legible.
Clean the interior regularly to remove inconsistencies and foreign matter to prevent electrical malfunctions.
Component:
Regularly check electrical connection components of Switchgear equipment to ensure reliability and prevent an increase in faults caused by looseness.
Reinforce loose bolts and bolts.
Lubricating:
Lubricate mechanical parts using the manufacturer's recommended lubricant.
Ensure the cleanliness and suitability of lubrication.
Insulation check:
Regularly check insulation performance using an insulation resistance tester.
Observe the condition of the insulation material and replace aging or damaged parts in time.
Electrical parameter test:
Regularly test current, voltage and frequency of Switchgear equipment to ensure they are within normal operating range.
For discovered anomalies, conduct further investigation and repair.
Protection device testing:
Regularly test the functionality of protective devices to ensure they are working as expected.
Update protection device settings to adapt to system changes.
Replace old parts:
Timely replace aging or consumed parts according to Shouke manufacturer's recommendations and equipment replacement.
Make sure replacement Switchgear equipment’s parts match equipment specifications.
Maintenance information:
Record details of each maintenance, including test results, maintenance operations and parts replaced.
Establish equipment maintenance history files to provide reference for future maintenance.
Training operators:
Provide necessary training for operators, including normal operation and emergency maintenance procedures of equipment.
Conduct regular operator training to ensure they are aware of the latest safety and maintenance requirements.
Through the above detailed testing and maintenance measures, high reliability and safety of switch cabinet equipment can be achieved, failures can be reduced and the service life of the switchgear equipment can be extended. Maintenance work needs to be performed by experienced electrical engineers or professional technicians and in compliance with relevant safety standards and manufacturer recommendations.
