Fully Automatic High-Efficiency High and Low Voltage Switchgear Power-On Test Bench
Dali Electric recommends
High Voltage Switchgear Test Device, used for factory commissioning and debugging of high and low voltage switchgear manufacturers, and can also be used for substation maintenance to replace the station DC operation power supply and other occasions requiring DC power supply. In power plants, substations, switchgear factories and other units, primary equipment is important, and secondary equipment is also important, because primary and secondary equipment form a whole, and only when both are in good condition can the safety of power production be guaranteed. Secondary equipment refers to the equipment that monitors, controls, regulates, and protects the working condition of primary equipment, and provides operating personnel with working condition or production command signals. Therefore, faults in the secondary circuit often damage or affect the normal operation of electrical equipment. Properly using and managing the electrical equipment of the secondary circuit is an important link to ensure the safety of power production. This test vehicle is designed and produced by our company based on the requirements of secondary circuit testing and trial, starting from the actual needs of users for secondary circuit testing. This product has the characteristics of full functions, small size, beautiful appearance, and easy movement, making it an ideal device for testing various parameters of secondary equipment.
