| PURPOSE: To equalize the voltage on each zinc oxide element by using the zinc element which can be used at an electric field higher than the conventional electric field by a specified number of times, and providing a lightening arresters having the discharge voltage, higher than that of a standard lightening arrester by specified %, in the vicinity of the opening end of a gas insulated switchgear. CONSTITUTION: For lightening arresters B1 and B2, zinc oxide elements, made of new composition that can be used in the electric field higher than the electric field used in standard lightening arresters A1 and A2 by about 1.5 times, are used. Therefore, the length of the lightening arrester B1 and B2 can be made shorter than the length of the lightening arresters A1 and A2 by 1/1.5 or less. Furthermore, the discharge voltage is made 10-30% higher. Therefore, the energy, absorbed by the lightening arresters B1 and B2 for the short-time overvoltage is less than that of the lightening arresters A1 and A2, and the size can be made compact. As a result, the voltages on the respective zinc oxide elements can be more equalized since the length of the lightening arrester B1 is shorter than the conventional value, and the transformer station, wherein insulation coordination is balanced as a whole and the reliability is high, is obtained. | ||||||

| A MEMS actuator is provided that produces significant forces and displacements while consumming a reasonable amount of power. The MEMS actuator includes a microelectronic substrate, spaced apart supports on the substrate and a metallic arched beam extending between the spaced apart supports. The MEMS actuator also includes a heater for heating the arched beam to cause futher arching of the beam. In order to effectively transfer heat from the heater to the metallic arched beam, the metallic arched beam extends over and is spaced, albeit slightly, from the heater. As such, the MEMS actuator effectively converts the heat generated by the heater into mechanical motion of the metallic arched beam. A family of other MEMS devices, such as relays, switching arrays and valves, are also provided that include one or more MEMS actuators in order to take advantage of its efficient operating characteristics. In addition, a method of fabricating a MEMS actuator is further provided. | ||||||

Dem Gegenkontaktsystem sind Abreißkontakte (146, 205) zugeordnet, die mit einer Lichtbogenlöscheinrichtung (219) versehen sind. Die Abreißkontakte werden von der Bewegung der Hilfsschienen gesteuert und sie schalten Potentialdifferenzen zwischen dem Gegenkontakt und den Scherenkontakten ab, so daß die Entstehung eines Lichtbogens zwischen den Scherenkontakten und dem Gegenkontakt verhindert wird. Zur Vermeidung von Überschlägen im Bereich der Abreißkontakte aufgrund kapazitiver Verschiebungsströme ist parallel zu den Abreißkontakten (146, 205) ein Bypaß-Weg (300, 301, 302) geschaltet, in dem vorzugsweise eine Funkenstrecke (300) eingeschaltet ist. Diese Funkenstrecke entspricht bei Auftreten einer bestimmten Potentialdifferenz an, so daß ein Potentialausgleich zwischen den einzelnen Bauelementen erreicht wird. |
