Problems solved by technology

The completion time of this process is about 70-100ms. During this period, there will be a period of "voltage sag" in the system voltage, which will cause the low-voltage protection of the internal equipment of the system to operate and cause a large-scale equipment power outage, which will bring huge losses to the enterprise. economic loss

Abstract

The invention provides an adaptive smart synchronous high-speed switching device. The amplitude, phase angle and zero-crossing point during short circuit can be calculated through current and voltage parameters when a sampling system is short-circuited. Balanced dynamic control of coil driving magnetic flux during a moving transient process is realized, the opening speed of the switch is adjusted automatically according to the short circuit state to satisfy requirements of different short circuit states on opening time. A Rogowski coil on a vacuum circuit breaker explosion chamber mounting base conducts sampling, monitoring and controlling of a current loop, and smart control and phase-splitting control of the switch and synchronous switching are realized.

Description

technical field [0001] The invention relates to the technical field of switching equipment, in particular to an adaptive intelligent synchronous high-speed switching device. Background technique [0002] At present, the opening time of the traditional vacuum switch is 30-50ms, and the closing time is 40-60ms. In order for the switch to operate accurately when the line fails, it must be equipped with a special microcomputer comprehensive protection device (referred to as comprehensive protection device). ), through comprehensive protection sampling current and voltage signals and making judgments to send action signals, so that the vacuum switch completes the opening or closing command and process. The completion time of this process is about 70-100ms. During this period, there will be a period of "voltage sag" in the system voltage, which will cause the low-voltage protection of the internal equipment of the system to operate and cause a large-scale equipment power outage, w...
