c. As shown in Figure 16, move the handle from the vertical
position to horizontal position, and maintain and withdraw the
locking plug and the fuse horizontally. Handle with care, to
avoid any damage to the fuse cylinder;
d. Check the silicone rubber sleeves for any damage, and the
contact button on the locking plug for any permanent
deformation;
e. Remove the blown fuse;
f. Insert the fuse into the insulation cylinder, clear and clean the
silicon rubber surface with alcohol cotton paper. Then apply
silicon grease evenly on the surface of the silicon rubber, and
press down the top pin of the locking plug;
g. Insert the fuse into the insulation cylinder horizontally, ensuring
the inner side of the fuse has good contact with the contact
button inside the insulation cylinder. Push the locking plug
slightly to make the handle's notch clutch onto the pin of the
cabinet. Then press the handle from the horizontal position to
vertical position (see Figure 18), to complete the installation of
the fuse.
THE FUSE SHALL BE SELECTED ACCORDING TO THE FUSE SELECTION
TABLE. IN THE THREEPHASE POWER GRID, EVEN IF ONLY ONE-PHASE
FUSE TAKES ACTION, ALSO REPLACE THE OTHER TWO-PHASE FUSES.
WHEN REPLACING, MAKE SURE THAT THE FUSE IS COOLED!

7. Cabinet connection and installation

Cooper series ring main units can make two different switchgears
connected together with a bus connector. The process does not
involve the process of SF6 gas. This connector consists of silicone
rubber plug-ins and contact buttons, installed between the two
bus insulators (bus exit) on the side of the switchgear, with
electric field distribution controlled by the semiconductor layer,
with contact buttons to carry current, to make adjacent switchgear
buses to connect in the electric circuit and have the joints
insulated. First, insert three bus connectors into the corresponding
bus insulators of one switchgear, and draw the adjacent
switchgear closer to it. During closing up, the bus connector shall
be aligned towards the center of the bus insulator, connect and
tighten these two switchgear cabinets with bolts.

8. Inspection and cleaning after installation

• To check the data on the nameplate;
• To check the control circuit line and voltage;
• Gas pressure indication (red/green);
• To remove the dust on the equipment due to installation;
• To remove instructions, leaflets and data no longer needed;
• To check all the fastening pieces for looseness, and remove the
tools and parts no longer needed on the installation site;
• To check the wirings on the installation site;
• To check the effectiveness of the interlocks.
