Abstract: In a metal clad switch for high voltage comprising cooperating contacts to close and to open the circuit, of which one of said contacts is a bushing contact, the provision of a movable metal disc in the cavity of said bushing contact, said disc being forced by a spring in a position, in which it lies flush with the edge of said cavity, when the switch is in its open condition in order to eliminate the unfavourable influence of the edge of said cavity on the electric field set up in the switch when the latter is alive.

Abstract: In a cylindrical capacitor having a gaseous dielectricum the relation between the coefficient of expansion of the material of the inner cylinder of the capacitor and the gas pressure, which is held steady, being such as to make the capacity of the capacitor substantially independent of temperature variations within the operational temperature range of the capacitor.

Abstract: The metal envelope of a gas insulated switch plant is divided into a number of detachably interconnected compartments which are separated from each other in gastight manner and insulating gas is supplied to these compartments. Some of the compartments are of such small volumes that the heat generated by a short circuit therein, for example, might cause a pressure rise of the insulating gas which is sufficient to rupture the compartment. A conduit is provided between each of these small compartments and another compartment which is itself of large enough volume, or which is cumulatively with the first compartment of large enough volume, so as to prevent such destructive pressure rise. Each such conduit is normally blocked or substantially blocked by a rupturable diaphragm which breaks, in response to the inception of a destructive pressure rise, to allow full flow communication between the two compartments so connected.

Abstract: A circuit-breaker is provided with relatively movable contacts and an actuating rod is attached to one of the contacts to effect separation of the contacts and opening of the circuit-breaker. The contact assembly is housed within an outer chamber which is subjected to insulating gas under high pressure and the contact assembly forms an inner chamber which, when the contacts are closed, is isolated from the outer chamber and which is vented to a pressure lower than the pressure in the outer chamber. A small net force acts on the movable contact to which the actuating rod is attached to maintain the contacts in closed condition. When the contacts are closed, the pressure differential existing between the outer and inner chambers is used in substantially balancing fashion and additional means is provided for cooperating with this differential pressure effect to establish the small net force serving to maintain the contacts in closed condition. When the contacts are open the pressure differential disappears and full pressure balance is effected so that both upon initial opening and continued opening movement as effected by the actuating rod, the actuating rod is subjected to very little mechanical stress. The opening of the contacts opens a valve formed between separable contacts and communicating the inner chamber with the outer chamber and allowing the insulating or extinguishing gas to rush past the contacts and axially through at least one of them for extinguishing the arc produced by opening of the contacts.
