The electric braking technology of high voltage switch electric operating mechanism is an important application of technology

but has not received enough attention. Therefore

the paper expounds the working principle of electric braking technology system and its technical characteristics

summarizes the common problems appeared in the engineering application and screening method

and carries out the tests for the prototype with brake parameter by using the Lab VIEW software. By analysis:the braking energy

turning the motor into his dynamo

the braking energy to make electric complete parking within 0.3 s. According to the different braking of motor circuit power supply category select:permanent magnet DC motor for DC power supply

using single resistance braking way; Series motor is single-phase AC power

adopts double resistance braking method. In the same brake circuit

motor circuit input DC power than the input AC power produced by the short braking distance and braking circuit is simple

reliable

better braking effect.
