ABB ZX0 Manual For Installation And Operation

Manual for installation and operation HB 600/05 en
ZX0 - block design
Gas-insulated medium voltage switchgear
Your safety first - always!
That‘s why our instruction manual begins with these recommendations:
− Operate the switchgear as prescribed for its intended purpose.
− Ensure that the technical data on the name plate and in the specification are not exceeded during operation of the switch­gear.
− With the aim of a smooth installation sequence and ensuring a high quality standard, have installation at site performed by specially trained personnel or managed and supervised by the ABB Service Department.
− Ensure that installation, operation and maintenance are only performed by specialist electricians familiar with this manual.
− Comply in full with the legally recognized standards (IEC / DIN VDE), the connection conditions of the local electrical utility and the applicable safety at work regulations.
− Follow the instructions in the documentation when performing any work on switching devices and switchgear.
− Keep all documentation accessible to all persons concerned with installation, operation and maintenance.
− The user’s personnel bear unlimited responsibility in all matters affecting safety at work and the correct handling of the switchgear in accordance with EN 50110 and national regulations.
− Always observe the five safety rules set out in EN 50110 on establishing and securing the off-circuit condition at the place of work for the duration of work on the switchgear. Gas-insulated switchgear are notable for maximum safety, as the circuit­breaker performs the earthing switch function in conjunction with the three position disconnector. The sequence of safety rules therefore deviates from that proposed in the standard as follows:
Isolate,
Check the off-circuit condition,
Earth and short-circuit,
Secure to prevent reconnection,
Cover or guard off adjacent live parts.
If you have any further questions on this manual, the members of our field organization will be pleased to provide the required infor­mation.

Note on safety
The internal arc classification to IEC 62271-200 confirms a tested degree of operator protection. The information on accessibility of the
switchgear as required by IEC 62271-200 can be found on the type plates of the panels. The coding is as follows (exemplary):
IAC AFLR 31,5 kA 1 sec
Duration of fault current Level of fault current Successfully tested accessibility of the area behind the switchgear (R – rear, only with pressure
relief duct and enclosed cable termination compartment)) Successfully tested accessibility of the area to the side of the switchgear (L - lateral) Successfully tested accessibility of the area in front of the switchgear (F- front) Switchgear installed in closed rooms with access restricted to authorised personnel Internal arc classification
The operator of the switchgear must prevent access by personnel to non-arc classified areas, for instance by issuing instructions.
Within the ratings stated on the type plate, the switchgear is safe for operating personnel in accordance with IEC 62271-200 when all system components are completely and properly installed.
Commissioning, servicing and extension work require special attention with regard to safety (see also IEC 62271-20 0 ).
Operator safety in accordance with IEC 62271-200 assumes that the conditions stipulated by us are complied with (see also Technical Catalogue TK 500).
The IAC qualification relies on a system consisting of at least three panels.
1)
At a room height of at least 2400 mm and a short-circuit current ≤ 21 kA (only possible with wall installation), the length of the switchgear system
must be at least 1600 mm.

1. Despatch and storage
The possible packaging methods are as follows:
− No packaging
1.1 Condition on delivery
− The panels have been assembled into system blocks ready for operation.
− The panel blocks have been routine tested to IEC 62271-
200.
− The busbar sockets are sealed with plastic film to protect them during transport.
The busbar sockets are not shockproof in this transport condition. Do not operate the switchgear
with sealed busbar sockets (e.g. on extendable end panels). Close off unused busbar sockets with shockproof blanking plugs (see section 2.3.3).
− In normal cases, the gas compartments have been filled
with sulphur hexafluoride (SF6) insulating gas to the rated filling pressure. When airfreighted, however, the panel blocks are delivered with reduced pressure.
− If delivered by airfreight, increase the pressure to the rated filling pressure before installing the panels (see instruction manual HB 605 E for the procedure to be adopted).
− Packaged in plastic sheeting
− Packaged in plastic sheeting and surrounded by protective cardboard
− Heat sealed in plastic sheeting with drying agent enclosed
− Packaged in aluminium foil in transport crate with drying agent enclosed
1.4 Handling
− The transport units are the panel blocks.
− Always handle the panel blocks in the upright position.
− Take account of the weight of the transport units when selecting the handling equipment.
Due to the high centre of gravity of the panel blocks, there is a risk that the transport units may tip over! Take all precautions to protect personnel and the materials
transported.
Only ever handle the panel blocks by
− The installation material and accessories and the docu­mentation are packaged separately from the panel blocks.
1.2 Delivery
Check the consignment for completeness and freedom from dam­age. Document any transport damage found on the waybill and inform us of it immediately. Take photographs of the damage.
1.3 Packaging
The panel blocks have been prepared for transport by the agreed
method and for the desired duration of any interim storage re­quired. Details of the length of preservation and the storage loca­tion (indoors or outdoors) can be found in the order documents. If the panel blocks are packaged, they are mounted on a pallet and secured to prevent them from slipping.
− fork lift truck,
− trolley jack,
− crane, or
− hydraulic lift trolley.
1.4.1 Handling by fork lift truck or trolley jack
The panel block must be standing on a pallet. The pallet must rest fully on the forks of the truck or jack. The high centre of gravity means there is a high risk of tipping.
Avoid jerky motions.
10 | Manual ZX0 HB 600 en - Revision 05
1.4.2 Handling by crane
− The methods of handling by crane differ, depending on the width of the panel blocks. Up to a block width of 1 m, there are lugs on the top of the panel modules for fastening of the suspension ropes (figure 1.4.2.1), and from a width of 1.2 m upwards there are transport crossbeams with lugs for fastening of the suspension ropes located at the bottom (figure 1.4.2.2).
− Attach suspension ropes of a sufficient load bearing capac­ity (see section 10, Technical data, for the panel weights) to the lugs with shackles (figure 1.4.2.1). The ABB scope of supply does not include suspension ropes and shackles.

Standard foundation frames are delivered to site completely pre­assembled.
Installation principle:
The foundation frames are bolted together at the front and rear.
Vertical alignment is effected by jacking screws. Brackets are
used to fasten the frames to the floor. The foundation frames are finally embedded in the floor topping to provide their load bearing capacity.
Detailed description of installation (Fig. 2.2.2.1)
- Position the foundation frame sections in the correct loca-
tions on the concrete floor.
- Align the foundation frame vertically with the four screws
(1), taking account of any deviation in floor level in the direction of the foundation frames which are still to be laid.
- Fasten the brackets (2) of the foundation frame to the
floor, using one knock-in anchor (5) and one screw (3) with dished washer (4) for each bracket.
- Slide a slot rod (6) into the front slot of the front section and, if the rear sections of the two frames to be connected are aligned (i.e. have the same depth) a slot rod into the rear slot of the rear section. Tighten the grub screws in the slot rods.
- Place the following foundation frame in the correct position on the floor, allowing the inserted slot rods to slide into the sections of the frame to be installed. Bolt the foundation frames together with two M 8 x 100 cheese head screws (7) and nuts and washers. Tighten the grub screws in the slot rods.
- Align the foundation frame vertically as described above and fasten it to the floor.
- Install the following foundation frames in the same way.
