Title:
OPENING/CLOSING OPERATION APPARATUS FOR MULTIPLE TYPES OF CIRCUIT BREAKER, AND FAULT DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/127160
Kind Code:
A1
Abstract:
The present invention relates to an opening/closing operation apparatus for multiple types of circuit breaker, and a fault detection method. The entire apparatus has a box structure and can output five control signals and five voltage signals, and therefore can control five circuit breakers at the same time. The apparatus is internally configured with a transformer, a rectifier, a high-power DC-DC converter, a PLC, an A/D analog-to-digital converter, five direct-current sensors and transmitters, five alternating-current sensors and transmitters, and various opening/closing relays. A panel comprises a liquid crystal touch screen, a circuit breaker control signal output terminal, a circuit breaker electric motor power source output terminal, a detection input terminal, an emergency stop button, an audible and visual alarm indicator, a manual opening/closing button, a voltmeter, an ammeter, a miniature circuit breaker, five groups of opening indicator lamps, five groups of closing indicator lamps, five groups of control signal indicator lamps, etc. Parameter setting, signal display, etc. can be implemented by means of the touch screen. By means of the apparatus, the operation test time is changed from daytime to all day, and the number of allocated operators is reduced.
