a. When setting the level, open the handle. After adjusting the level, close the handle
to the slot.
b. After the check is complete, tighten the protective cover for the level switch.
8. There is no packing residue on the transformer surface, and there is no foreign matter in
the transformer room.
9. Check the external air insulation distance. Whether the air insulation distance between
different voltage grade bushing and bushing to ground conforms to relevant standard.
10. The oil leak port of the transformer room is not blocked.
11. The screen door of the transformer room is closed and locked.
7.2.4 LV Cabinet
1. Disconnector are turned off.
2. The copper bar is not deformed, and no foreign matter is on the copper bar.
3. Measure the ground resistance of Circuit breaker in and out of the copper bar; in the
system that neutral point of the transformer is not grounded, the input & output wiring to
grounding resistance should be M Ω level; In the neutral point grounding system,
outgoing wiring copper bar resistance shall be M Ω level and phase to phase resistance
shall be M Ω level. (need to disconnect the auxiliary circuit breaker, or phase to phase
resistance is generally 0 Ω ).
4. Measure the fuse resistance. Resistances of three phases shall be small and the value
is similar.
5. Lightning protection status indicates green.
6. Pull the current terminal chip to the open position and measure the resistance at both
ends of the fracture. The value of three-phase resistance should be small and close.
After the measurement, restore the current terminal to the connected position and
tighten it. The standby current loop shall be shorted and grounded.
7. Apart the grounding yellow green wire of the secondary circuit and measure secondary
loop to the ground resistance and resistance should be M Ω level. Recover the
grounding wire and the resistance shall be 0 Ω.
8. The installation bolt of input cable has been tightened, and the cable is not loose after
pulling.
9. The cable inlet hole has been sealed.
10. Each component is intact.
11. Clear all foreign matter in the switchgear, such as tools and remaining materials.
