CLAIM OF PRIORITY [0001] This application claims priority from Japanese application serial No. 2004-237382, filed on Aug. 17, 2004, the content of which is hereby incorporated by reference into this application. FIELD OF THE INVENTION [0002] The present invention relates to a fully vacuum insulated type vacuum switchgear, and more particularly to a technology for space saving and improving assembly of a vacuum insulated switchgear. RELATED ART [0003] Vacuum switchgears are used in power transmission lines, which are called metal-clad type switchgears. The switchgears as disclosed in patent document No. 1 comprise a metal box which accommodates vacuum circuit breakers for interrupting load current or failure current. The metal-clad type switchgear are provided with a disconnector and an earth switch for securing safety of operators at the time of inspection and/or maintenance of the load, detectors for line voltage or current, protection relays, etc. [0004] Though there various types of insulation systems for vacuum switchgears, in fully vacuum insulated switchgears, an earthed vacuum container encloses a plurality of switches, such as a circuit breaker, a disconnecting switch, a load break switch and/or earthing switch, so that the vacuum switch portion is remarkably downsized. Patent Document No. 1: Japanese Patent Laid-Open 2000-268686 [0005] The plural switches are enclosed in a single vacuum container to downsize the switchgear; in order to downsize the vacuum switchgear system, driving mechanisms for driving the respective switches should be downsized. [0006] As the switchgear is downsized, operation efficiency of assembly and inspection and/or maintenance decreases, in general. Accordingly, switchgears that do not hinder the operation efficiency or assembly efficiency are desired. SUMMARY OF THE INVENTION [0007] The present invention aims at saving installment area of the vacuum switchgear by downsizing it, without decreasing efficiency of assembly and maintenance operation. [0008] A vacuum insulated switchgear of the present invention comprises a plurality of vacuum insulated switchgear modules; each comprising, [0009] a vacuum container; [0010] a vacuum insulated switch having a movable contact connected to a movable electrode and a fixed contact connected to a fixed electrode for interrupting and closing current; [0011] an operating rod connected to the movable electrode and connected to a magnetic drive mechanism; and [0012] a connecting mechanism for operating the operating rod; the vacuum container, wherein the magnetic drive mechanism and the connecting mechanism are aligned on a straight line, wherein the magnet drive mechanism has a shape of a rectangular parallelopiped shape. BRIEF DESCRIPTION OF THE DRAWINGS [0013] FIG. 1 is a side cross sectional view of an inside structure of a vacuum insulated switchgear of one embodiment according to the present invention. [0014] FIG. 2 is a single line-wiring skeleton of the vacuum insulated switchgear of the first embodiment shown in FIG. 1. [0015] FIG. 3 is a front view of the vacuum insulated switchgear of the first embodiment shown in FIG. 1. [0016] FIG. 4 is a side view of the inner structure of the first embodiment. [0017] FIG. 5 is a top view of the magnet drive unit for explaining the operation mechanism. [0018] FIG. 6 is a cross sectional view of an electro-magnet for explaining the structure of the electro-magnet. [0019] FIG. 7 is a diagrammatic view of an electro-magnet for explaining the operation. [0020] FIG. 8 is a diagrammatic view of another example of the electro-magnet for explaining the operation. [0021] FIG. 9 is a diagrammatic view of a further example of the electro-magnet for explaining the operation. [0022] FIG. 10 is a top view of a connecting unit for switch contacts of a part of the three phase vacuum insulated switchgears. Continue reading...
