Pantograph disconnectors type GSSB

General

The pantograph disconnector consists of three poles. Each pole con­sists of one support insulator, one rotating insulator, the pantograph mechanism and a counter contact.

Insulators

The disconnectors can be equipped with insulators in accordance with IEC, ANSI or DIN specifications.

Pantograph mechanizm

The pantograph mechanism is installed on the support insulator and transfers the move­ment of the rotating insulator to the arms of the pantograph disconnector. The mechanism is housed in an aluminium enclosure, protecting it again­st pollution and ice. The springs that compensate the weight of the pantograph arms are also installed in this housing. Each pantograph is equipped with four aluminium arms to ensure a rigid construc­tion with a very high short circuit rating.
The main contacts are made of copper, with a silver plated surface. The counter contact is a horizontal copper bar, silver-plated, which has to be connected to the busbar system.

Earthing switch

Hapam pantograph disconnectors may be equipped with earthing switches. The earthing switch consists of an Aluminum tube, provided with silver-plated contacts at both ends.

Drive mechanism

The disconnectors and/or earthing switches can be single-pole or three-pole operated by means of a motor-operated drive mechanism or a manual-operated drive mechanism.
In case only one drive mechanism is used for three-pole operation, the poles are interconnected by means of adjustable coupling rods. The drive mechanism also houses the auxiliary contacts for position indication.

Testing

The disconnectors and earthing switches are designed and tested in accordance with latest IEC specifications. Hapam main­tains a q­uality assurance system according to ISO 9001, certified by DEKRA (previously known as KEMA).

Installation

The disconnectors and earthing switches are pre-assembled and ad­justed in our works as complete as possible. The construction is designed so that all disconnectors can be instal­led and adjusted at site very easily, without the need of any special tools. Hapam provides clear installation instructions and assembly drawings.

Maintenance

The disconnectors and earthing switches supplied by Hapam are d­esigned so as to ensure that they are virtually maintenance free. However, to warrant a long and trouble-free service period, we advise that a visual inspection of the contacts and bearing points be carried out at regular intervals.
