Abstract

The invention discloses a bypass quick-switching switch and an uninterrupted power operation method thereof. The invention relates to electric power overhaul equipment, in particular to a bypass quick-switching switch and a bypass uninterrupted power operation method. An on-line monitoring system for bypass uninterruptible operation realizes the quick access and unperceptible switching of a bypasssystem, improves the uninterruptible operation level, and improves the power supply reliability. A circuit breaker module which is electrically connected with the intelligent controller module through a cable is included; the circuit breaker module comprises a main loop, a three-phase current transformer, an incoming line side three-phase voltage sensor, an outgoing line side three-phase voltagesensor, a spring operating mechanism, a switch position signal module and a current and voltage secondary protection module. A limiting shaft II rotates through an opening linear driving mechanism torelease an opening swing plate. The switch has the characteristics of convenient installation and long plugging service life.

Description

technical field [0001] The invention relates to electric power maintenance equipment, in particular to a bypass quick-cut switch and a bypass non-stop operation method. Background technique [0002] With the rapid development of urban construction and the intensification of new construction and renovation of distribution networks, people have higher and higher requirements for less power outages or even no power outages during planned maintenance and emergency repairs. At present, there are few breaking switches for the overhead lines of the distribution network in various cities. When the overhead lines are overhauled or repaired, it usually requires a power outage of the entire line, or a sudden operation failure of the cable line, and it takes a long time to find the fault point and repair it. ; In addition, the city's key power-consuming units, or major events, etc. require high power supply reliability. [0003] At present, the maintenance and replacement of power dist...
