Dimensions: 360mm(L)×280mm(W)×300mm(H) Weight: 9kg 2. Performance characteristics 1. Performance time: inherent opening and closing time of 12 breaks, phase-to-phase synchronization, phase-to-phase synchronization. Reclosing: closing-opening, opening-closing, opening-closing-opening process time of each break: one opening time, one closing time, two closing times, short-circuit time, no current time value. Bounce: closing bounce time, number of bounces, bounce process, bounce waveform of each break; rebound amplitude of opening of each break. Speed: just opening, just closing speed, maximum speed, time-travel characteristic curve. Travel: total travel, opening distance, overtravel, overshoot travel, rebound amplitude. Current: opening and closing current value of opening and closing coils, current waveform. Action voltage: The machine provides a DC30 ~ 250V/10A digital adjustable circuit breaker action power supply, automatically completes the circuit breaker low voltage action test, and measures the circuit breaker action voltage value. 2. Features It is suitable for mechanical characteristic tests of all types of SF6 switches, GIS combination electrical appliances, vacuum switches, and oil switches produced at home and abroad. With super strong anti-interference ability, it can easily test and accurately measure even when the bypass bus of the 500KV substation is energized. Universal speed sensor (optional), linear travel speed sensor, and rotary speed sensor are extremely convenient and simple to install. After the switch is actuated once, all the data of the switch mechanical characteristic test and the corresponding waveform map are obtained. The host can store on-site test data, and the real-time clock in the machine is convenient for archiving and saving the test date and time. The host has a large screen, wide temperature, vertical perspective, background light LCD, and all Chinese displays all data and maps. The LCD contrast is electronically adjusted and power-off memory. Chinese menu operation is easy to use. The instrument has a built-in printer to quickly print all data and maps at any time.
