LDGKC-HA High Voltage Switch Characteristics Comprehensive Tester is a high-precision power testing device based on an embedded industrial computer. It is primarily used for testing the mechanical and dynamic characteristic parameters of various high-voltage circuit breakers (such as vacuum, SF6, and low-oil circuit breakers). The instrument has 12-channel break measurement capability, and can simultaneously test key parameters such as closing/opening time, synchronicity, bounce, speed, travel, and coil current. It has a built-in DC 6～270V adjustable operating power supply and supports multiple control modes including internal triggering, external triggering, and manual triggering. Equipped with a 9-inch color touchscreen, high-speed thermal printer, large-capacity storage, and USB interface, it supports data upload to MES, ERP, and other platforms. Suitable for substations, power plants, and other field environments, it features strong anti-interference capabilities, convenient installation, and intelligent operation.
