Function
2.1
Disconnector
2/106
Electrical isolation of parts of networks High-voltage disconnectors are used for the electrical isolation of electrical high-voltage networks. When switched off, they form a visible isolation distance. High-voltage disconnectors are switched under no-load conditions. Small capacitive or inductive currents, of the kind that occur during the discharge of disconnected overhead-line or cable sections, are controlled. Outdoor installation and formation of groups The type SGF two column rotary disconnector described in these service instructions is a single - pole disconnector for outdoor installation. Two or three poles can be coupled to form a group. Standards The type SGF two-column rotary disconnector conforms to the following standards : IEC 62271-102 (2001-12) & IEC 62271-1 (2007-10)
DIN/VDE 0670 Part 2/Oct 1991 and Part 1 000/Aug 1984
2.2
Earthing Switch Earthing and short-circuiting In order to earth and short-circuit switched-off parts of plant, it is possible to mount one or two earthing switches per pole.
2.3
Variants Selection of variant of client The type SGF two-column rotary disconnector is available in a wide range of variants. These service instructions are valid for all variants. The information on the different variants is structured in such a way that a clear distinction can be made.

Mode of Operation
5.1
General The type SGF two-column rotary disconnector has separate operating mechanisms for the disconnector and the earthing switch. Prevention of automatic operating or closing When the equipments switched on or off, a dead-center position is passed through just before the end positions are reached. This prevents the automatic opening or closing of the disconnector or earthing switch as a result of : Short-circuit
External influence : (e.g. storm or earthquake)
5.2
Disconnector
Figure 5 : Mode of operation of type SGF two-column rotary disconnector (example : 3-pole in parallel arrangement)
Operating mechanism :The operating mechanism (75) of the disconnector tr ansfers the operating energy via the operating rod (37) to the rotary pedestal (70). The diagonal rod (68) connects the two rotary pedestals of each pole. Consequently, both pole halves are moved simultaneous ly. The support insulators (201) transfer the torque to the two current-path halves (5, contact side) and (6, 0 finger side). These pass through an angle of rotation of 90 during switching. Current transfer :During switching-on, the counter-contact (67) glides between the contact fingers (66). This establishes the connection between the two current-path halves. The current is transferred via tulip-type contacts in the rotary heads (284) to the high-voltage terminals (17). Mechanical coupling inside a disconnector group :Via the coupling rods (15), the movement of the operated pole is transferred simultaneously to the other poles of a disconnector group.
1HDB050016-YN

Earthing Switch
Figure 6 : Mode of operation of earthing switch (example : 3-pole in parallel arrangement)
Operating mechanism :The operating mechanism (77) of the earthing switch transfers the operating energy via the operating rod (71) to the earthing-switch shaft (337). The tubular contact arm (23) swivels up (ON) or down (OFF). During switching-on, the contact fingers (20) glide over the earthing contact (18). In the ON end position, they are in preloaded contact against the stop. Earthing connection :The earthing connection (79) connects the tubular contact arm (23) to the earthed sectional-steel base frame (221) of the disconnector. 5.4
Interlocking The disconnector and the earthing switch can be interlocked according to the following principle : •
Disconnector only ON when earthing switch OFF
•
Earthing switch only ON when disconnector OFF
Interlocking is mechanical and/or electrical, depending on the version
Note : Mechanical interlocks between disconnector and earthing switch are fitted at the factory. Retrofitting is not possible.

Shipping and Storage
8.1
Shipping
13/106
The equipment is shipped on pallets, or in boxes . Note : After unpacking, check all supplied equipment immediately for shipping damage. Report shipping damage without delay to the forwarding agency. 8.2
Storage Caution : In the case of inappropriate storage of the individual components, there is the risk of ingress of water. For this reason, disconnector parts and operating mechanisms must always be stored in the mounting position. It is advisable to leave all assemblies in the shipping packing until the start of mounting in order to protect against contamination and damage. Special Note : Operating mechanisms are supplied in packed condition. This protects the operating mechanisms against corrosion within a limited time and in a dry atmosphere. It is advisable not to open this packing until just before the start of mounting. Caution : In the case of lengthy storage and/or a damp atmosphere , there may be undesired formation of condensation in the operating mechanisms. If the shipping time and storage time together amount to more than 6 months or if operating mechanisms are stored in a damp atmosphere, the special packing must be removed immediately and the electrical heating of the operating mechanis ms must be started. Before doing this, remove bags with desiccative from the operating mechanisms !

Mounting, General The type SGF two-column rotary disconnector can be mounted in two positions Horizontal (standard)
Vertical (must be expressly specified when ordering and is only possible for rated voltage < 170 kV)
Note : For vertical mounting of the disconnector, you require the additionally supplied documents. Should the documents not have been supplied, pl ease send for them. Our address and telefax no. are given on the left. The internal parts of the operating mechanisms (e.g. alarm switches and contractors) are not resistant to outdoor climates. For this reason, they must be protect ed against moisture during mounting. 9.1
Tools and Materials Lifting tackle The lifting tackle for lifting the disconnector poles must have a lifting capacity of at least 500 kg. Special tools and material In addition to the standard tools, the following special tools and materials are required for mounting.
Brass-wire brush or treatment of copper surface
Steel-wire brush for treatment of aluminium surfaces
Steel-wire brush for treatment of zinc surfaces
Contact grease Molykote DC55
Cleaning agent for silver faced surfaces (Volatile inorganic solution like acetone, carbon tetrachloride or equivalent)

Mounting of Disconnector Note : If you suspect shipping damage, check the spacing dimensions of the contact Figure (66) Figure 66.
The disconnector pole can be mounted either on the supporting structure or in front of the supporting structure. If mounting in front of the supporting structure, first lift the completely mounted disconnector pole onto the supporting structure and then align and tighten it there. Note : Remember that the materials for fixing the disconnector bases (2) on the supporting structure are not included in the scope of supply. Caution : T he transportation angles (328) Figure 13 must be mounted in place and may under no circumstances be removed during this mounting phase.
Caution : The diagonal rods (68) Figure 13 have been adjusted at the factory for the precise engagement of the main contacts. The adjustment may only be changed by ABB-trained specialist erectors.

Mounting of Operating Mechanism for Disconnector Note : The mounting side of the operating mechanism is apparent from the position of the disconnector operating lever (69) Figure 18.The pole on which the operating mechanism is mounted can be freely selected. In the case of mechanical interlocking, however, the operating mechanism must always be mounted on the pole with the interlocking segments.
Note : Make sure that the operating mechanism is in the ON position (as-delivered state). If the operating mechanism is in the OFF position, set it to the ON positi on using the emergency hand crank (39) Caution : In the case of a motor-operated mechanism, test operations may only be carried out using the emergency hand crank (39). Do not use a drill. 11.1

Direct Mounting Note : Make sure that the operating mechanism is in the ON position (as-delivered state). If the operating mechanism is in the OFF position, set it to the ON position using the emergenc y hand crank (39). Caution : In case of motor-operated mechanism, test operations may operations may only be carried out using the emergency hand crank (39). Do not use a drill. Note : Make sure that the disconnector poles is in the OFF position before mounting the operating mechanism. Mounting steps : 1.
Unpack operating mechanism (77)
2.
Tighten operating mechanism to disconnector base (2)

•
Separate mounting if measurement m3 = 6 ... 12 m
•
Separate mounting laterally offset with measurement m1 (max. 4 m)
Note : Make sure that the operating mechanism is in the ON position (as-delivered state). If the operating mechanism is in the OFF position, set it to the ON positi on using the emergency hand crank (39). The disconnector pole must be in the OFF position. Note : If a manual operating mechanism is envisaged for the earthing switch, ensure when mounting that there is sufficient clearance for the operating lever (367) of the operating mechanism Figure 38.
