Other four sections of buses are carried out normal ground, route selection monitoring, during ground connection arc-extinction device compensation of ground produce earth current；
(3) 10KV mono-section and tri-sections of partition runnings of 10KV, 10KV tetra-sections, 10KV two-stage nitration bus paired running
1XH, 3XH, 4XH put into operation, and 2XH also transports or exits；1XX with 1XH coordinates operation, 3XX with 3XH coordinates operation, 2XX and 4XX
Coordinate operation with 4XH, 92 bus connection switch position contacts are to closing position, and loop turns on, and auxiliary reclay JJ3 starts, respectively to four sections
Bus carries out normal ground, route selection monitoring, the earth current that during ground connection, arc-extinction device compensation of ground produces；
(4) mono-section of partition running of 10KV, 10KV two-stage nitration, 10KV tri-sections, tetra-sections of bus paired runnings of 10KV
1XH, 2XH put into operation, and 3XH, 4XH also transport or exit；1XX with 1XH coordinates operation, and 2XX, 3XX and 4XX coordinate fortune with 2XH
OK, 1#, 2# bus connection switch position contact is to closing position, and loop turns on, and auxiliary reclay JJ2 starts, 92 bus connection switch position contacts
To closing position, loop turns on, and auxiliary reclay JJ3 starts, and four sections of buses carries out normal ground, route selection monitoring respectively, during ground connection
The earth current that arc-extinction device compensation of ground produces；
(5) 10KV mono-section, 10KV two-stage nitration partition running, 10KV tri-sections, tetra-sections of bus paired runnings of 10KV
1XH, 2XH, 3XH put into operation, and 4XH also transports or exits；1XX with 1XH coordinates operation, 2XX with 2XH coordinates operation, 3XX and 4XX
Coordinate operation with 3XH, 1#, 2# bus connection switch position contact is to closing position, and loop turns on, and auxiliary reclay JJ2 starts, the most right
Four sections of buses carry out normal ground, route selection monitoring, the earth current that during ground connection, arc-extinction device compensation of ground produces.
