High and Low Voltage Switchgear

BYT High and Low Voltage Switchgear is applied to receive and distribute the electrical energy in three-phase AC power system with rated voltage 3, 6, 10KV and rated frequency 50HZ, especially for the frequently operated occasion. Its busbar system is a single busbar (which can derive the single busbar with bypass and double busbar structure). The switchgear cabinet is in line with the requirements of the National Standards GB3906 3-35KV AC Metal-enclosed Switchgear and the international Standard IEC298.

Quality Assurance Factory Testing Procedures

Visual Inspection：Inspect the switchgear for any physical damage, such as scratches, dents, or corrosion. Ensure that all labels, nameplates, and markings are clear and correctly placed.
Insulation Resistance Testing：Use an insulation resistance tester to measure the insulation resistance between live parts and earth, as well as between different phases.
Mechanical Operation Testing：Test the mechanical operation of circuit breakers, switches, and other moving parts to ensure they operate smoothly and correctly. Verify the functionality of locking mechanisms to prevent accidental operation.
Electrical Performance Testing：Check the continuity of electrical connections to ensure there are no open circuits or short circuits. Conduct tests under rated load conditions to ensure the switchgear operates correctly and within specified limits.

Temperature Rise Testing：Run the switchgear at rated load for a specified duration and measure the temperature rise of various components to ensure they remain within safe limits.
Short-Circuit Withstand Testing：Perform short-circuit tests to verify that the switchgear can withstand the thermal and dynamic forces resulting from short-circuit conditions.
Protection Level Testing：Verify the ingress protection (IP) rating of the switchgear to ensure it meets environmental protection standards.
Electromagnetic Compatibility Testing：Conduct tests to ensure that the switchgear operates correctly in the presence of electromagnetic interference and does not emit excessive electromagnetic interference.
