Abstract:

A Polish SME from Upper Silesia developed a new kind of electric switch. Using a manual manipulator, the switch realises remote and local on/off switching of currents up to 4000A (in electrical networks of up to 1000V), remote switch-off and mechanical interlocking after it. Lack of voltage precludes switch-on. The company is looking for partners for co-operation.

Description:

A Polish SME from Upper Silesia developed a new kind of electric switch with 3 small vacuum chambers with operating contacts, situated coaxially on isolated traverse connected with inductive-dynamical power transmission and a manual manipulator. Extinguishing vacuum chambers are encased with an insulating cylindrical shield, which fulfils ecological safety requirements. A line displacement sensor shows the position of contacts in extinguishing vacuum chambers. Axial functioning of movable contacts is performed by a power transmission system as a consequence of the movement of a disk made of conducting material, under the influence of pulse magnetic pool in the spiral coil circuit or by the manual manipulator. The position of open contacts is blocked by voltage release. High electro-dynamic endurance of current lines is achieved by the forces of atmospheric pressure.

Innovative Aspects:
- Coaxial displacement of power transmission, and contacts in extinguishing vacuum chambers connected by inductive-dynamical drive and a manual manipulator in a cylindrical housing
- Switching-off interlock and sensory demonstration of the contacts position in extinguishing vacuum chambers
- Remote on/off switching of electrical circuit by inductive-dynamical power transmission
- Local on-off by manual manipulator with mechanical interlock of remote switch-off

Main Advantages:
- Remote and local control by inductive-dynamical drive and electric circuits connection by manual manipulator with mechanical interlock of remote switch-off and switch-on interlock in case of no voltage.
- Small dimensions.
- Free work position.
- Energy-saving pulse power transmission.
- Little power losses at transfer operation.
- Ecologically safe, tremor and stroke resistant.
- High durability.
