LOAD-BREAK SWITCHES

LOAD BREAK SWITCHES COMBINED WITH DISCONNECTORS AND FAST EARTHING SWITCHES, 560_SERIES – 561_SERIES – 562_SERIES

DESCRIPTION

Load break switches combined with disconnectors and fast earthing switches series EDJAN_560, EDJAN_561 and EDJAN_562 are designed for MV(1,5-7,2kV) electro-energetical mining applications. Apparatuses for indoor switchgears series EDJAN_563, 564, 565 for voltage 12, 17.5 and 24 kV are being developed. Offered apparatuses are compliant with relevant standards, and they introduce many patent protected innovations. Edjan Load break switch design proved its reliability over many years of exploitation in heavy conditions of coal mines, where e.g. it is a part of longwall shearers power supply units.

Load break switch combined with disconnector and fast earthing switch comprise all features of apparatuses that they consist of.

Special versions of apparatuses can be equipped with integral electric drive.

Load break switches dedicated to longwall shearers are equipped in MV fuse bases for auxiliary transformers protection. Additionally they may be equipped also in MV auxiliary contacts required for circuit’s resistance examination. Mechanical interlocks ensure safety during this examination and when switching from test to work position.

FEATURES & BENEFITS
Load break switches inegrated with disconnectors and fast earthing switches EDJAN comprise of following advantages:

• increase of occupational safety by elimination of the risk of improper connecting performance – applied internal locking system prevents the short circuit activation of the earthing switch if the load break switch is in conduction state;
• combination of three devices in one compact unit gives the construction resistant to shocks and vibrations;
• application of patented load break switch contacts solutions allowed to achieve ability to switch high power;
• special, patented design of the support plates enables the movement of contacts inside the apparatus, what results in significant reduction of overall dimensions in comparison with known constructions;
• single lever to operate the integrated apparatus;
• …

DISCONNECTORS

DISCONNECTORS COMBINED WITH FAST EARTHING SWITCHES, 530_SERIES

DESCRIPTION

Disconnectors combined with fast earthing switches EDJAN 530 SERIES are available in two versions:

1. Standard;
2. Three-position.

They are designed for electro-energetical mining applications or MV indoor switchgears (3,6 – 24 kV). All apparatuses have appropriate certificates to prove the conformity to relevant standards and their innovativeness is protected by many patents.

Fast earthing switches EDJAN have the highest class “B”, which within the meaning of standards means that they do not require the maintenance of the main contacts for the expected service life and only slight maintenance of remaining parts.

FEATURES & BENEFITS

Disconnectors combined with fast earthing switches EDJAN are characterised by original design that stands out by:

• moving contacts are blocked in position of conduction as well as in position of earthing;
• special design of moving and fixed contacts allows to achieve very high voltage-current performance;
• apparatus fixed contacts are made in special technology to ensure high reliability and parameters stability;
• construction of earthing switches allows contacts position identification from 5 directions;
• disconnectors combined with fast earthing switches are available with optional low-voltage auxiliary contacts to indicate operating position;
• …

FAST EARTHING SWITCHES

FAST EARTHING SWITCHES 570_SERIES, 500_SERIES, 520_SERIES

DESCRIPTION

Fast earthing switches EDJAN are designed for electro-energetical mining applications or MV indoor switchgears (3,6 – 24 kV). All apparatuses have appropriate certificates to prove the conformity to relevant standards and their innovativeness is protected by many patents.

Fast earthing switches EDJAN have the highest class “B”, which within the meaning of standards means that they do not require the maintenance of the main contacts for the expected service life and only slight of remaining parts.

Any direction of the drive shaft is available for those apparatusses.

FEATURES & BENEFITS

Fast earthing switches EDJAN are characterised by original design that stands out by:

• moving contacts are blocked while in operation;
• fixed contacts are constrained accurately to supporting dielectric plates that are permanently bound to the base of earthing switch;
• drive elements are enclosed inside rectangular profiles
• The apparatuses may be equipped with the driving gear, that allows drive transmission in any direction in relation to the base;
• special design of moving and fixed contacts allows to achieve very high voltage-current performance;
• construction of earthing switches allows contacts position identification from 4 directions;
• fast earthing switches are available with optional low-voltage auxiliary contacts indicating status of the apparatus;
