Abstract
The invention relates to a 220kV switch open-phase protection teaching and training device. A hard insulating plate serves as a control loop panel which is provided with a terminal board, an A-phase auxiliary switch, a B-phase auxiliary switch, a C-phase auxiliary switch, a time relay, a middle relay and an indicating lamp. An electrical element is arranged on the hard insulating plate according to the actual position of a 220kV switch control loop, and wiring is carried out according to the wiring mode of the 220kV switch control loop. A normally-open contact of the A-phase auxiliary switch, a normally-open contact of the B-phase auxiliary switch and a normally-open contact of the C-phase auxiliary switch are arranged at the switching-closing positions of all phases of a breaker. One end of an open contact of the time relay and one end of an open contact of the middle relay are connected with a positive pole of a power source. The other ends of the open contacts are connected with the indicating lamp connected with a negative pole of the power source. The teaching and training device can simulate the actual operation state of open-phase protection of a 220kV switch and is mainly applied to teaching, training and practicing of substation maintenance personnel in the power transformation field; principle study, operation practice, trouble removal drill and the like can be provided for the maintenance personnel, the quality of the maintenance is improved, the maintenance efficiency of the maintenance personnel is improved, and the reliability of power supply is improved.
