HUGHES MOTOR DRIVESDESCRIPTION
Hughes EOA motor drive series is designed and manufactured in Sweden and introduces a wide range of motor operation mechanisms for full remote control of disconnectors and earth switches for different applications. Information on Hughes disconnectors is here.
The EOA motor drive types:
- Rocking type. This type of motor drives is designed for disconnectors with vertical motion;
- Rotating or torsional type. This type of motor operating drives can be connected to most existing disconnectors with horizontal motion control rod;
- Motor drive with auto sectionalizing function. This type of motor operating drives is designed for automatic sectionalising and for manual remote control of disconnectors;
The EOA motor drive model range:
- EOA500 universal motor drive for disconnectors in electrical distribution networks and railways;
- EOA501 universal motor drive for disconnectors in electrical distribution networks with wider cabinet for large / solar batteries;
- EOA600 motor drive for railway disconnectors;
- EOA650 motor drive for tram disconnectors;
- EOA700 motor drive for rotary disconnectors in railway and high voltage applications;
- EOA501TVS motor drive with autosectionalizing functions for disconnectors in electrical distribution networks;
The EOA motor drive includes:
- External cabinet made of non-magnetic stainless steel (compulsory);
- EOA motor mechanism (compulsory);
- Built in components (compulsory and optional);
- External accessories (optional);
HUGHES MOTOR DRIVEADVANTAGES
The EOA motor drive of the latest generation has the following advantages:
- Complete solution from a pole to SCADA system;
- Low maintenance. Hughes products are built to remain in operation for more than 30 years without major maintenance due to the highest quality materials used in the construction.
- Easy installation and compatible with most disconnectors;
- Multiple power options: voltage transformer, insulation transformer or solar panel;
- External cabinet (1) of highest quality stainless steel is available in many sizes. The use of stainless steel in accordance with DIN50049 / 3.1B, thanks to its non-magnetic properties, completely eliminates the occurrence of any kind of corrosion, including electrochemical corrosion over the entire life of the cabinet;
- Special double roof (2) prevents the accumulation of the water / snow on the cabinet and protects from overheating of the internal cabinet in hot climates;
- Padlock facility handle (3) protects from unauthorized access;
- Protection lips (4) preventing accumulation of the water drops under that cabinet;
- Rugged pole mounting brackets (5) for different pole types;
- Door alarm switch (6) activates when the door is opened and sends the signal to the SCADA system. This feature notifies about access to the cabinet;
- Local operation panel (7) with indicators;
- Connector (8) for remote control antenna;
- Multiple cable glands (9) in the bottom of the cabinet;
- Different motor mechanism principles with exact fit for its purpose;
