| 20080257865 | Gas circuit breaker - A gas circuit breaker includes a grounded tank corresponding to each one of the plurality of phases, a bushing, an upper housing, and a lower housing, those mounted on a base that is supported by a frame. The grounded tank and the upper housing are located on a plane. The lower housing is connected to the grounded tank with a connecting unit such that the lower housing can be moved from a first position for operation lower than the plane to a second position for transportation substantially on the plane. | 10-23-2008 |
| 20090166332 | Gas-insulated switchgear apparatus and gas filter device - A gas tank is hermetically filled with an insulating gas. A gas filling opening is provided on the gas tank, which includes a flange at its end. A gas filter device is fixed to the gas flange of the gas filling opening. The gas filter device includes a gas filter formed with a porous insulating material having pores with a diameter in a range from tens of micrometers to hundreds of micrometers. The gas filter has stability against the insulating gas and a decomposition product of the insulating gas. | 07-02-2009 |
| 20120138573 | PLUG-IN PRIMARY POWER CONNECTIONS OF TWO MODULES OF A GAS-INSULATED HIGH-VOLTAGE SWITCHGEAR ASSEMBLY - A gas-insulated switchgear assembly having a first module and a second module, which each have a gas area, which is in the form of a pressure vessel, is filled with an insulating gas and has at least two phase conductors. The first module is connected to the second module such that the first gas area and the second gas area are hydraulically separated from one another by an insulating body, while the phase conductors in the first module are electrically connected to the phase conductors at the same electrical potential in the second module. The at least two phase conductors in the first module can be electrically connected to the at least two phase conductors at the same electrical potential in the second module, in each case via a detachable plug connection. | 06-07-2012 |

| 20130032575 | METAL-ENCAPSULATED, GAS-INSULATED, COMBINED SWITCH DISCONNECTOR AND EARTHING SWITCH - An exemplary switch having a housing that includes one contact bolt per phase. Each contact bolt moving along a longitudinal axis. In a first position on the axis, the contact bolt connects two active parts to one another. In a second position on the axis, the contact bolt is connected to a fixed earthing contact piece. A drive motor actuates the contact bolts via a drive spindle. The lines of movement of each contact bolt all phases lie in a common plane, wherein each contact bolt is driven by one insulating spindle, which is aligned with the line of movement. The drive spindle lies in the plane of the lines of movement and runs perpendicular to the insulating spindles and is coupled to each insulating spindle via a respective deflecting gear mechanism. The deflecting gear mechanism for the drive of the contact bolts is accommodated in the earthing contact pieces. | 02-07-2013 |
| 20130161290 | GAS CIRCUIT BREAKER - A gas circuit breaker comprising: a sealed tank; two breaking sections disposed in the sealed tank; a bracket to support movable parts of the breaking sections while enabling switching operation of the movable parts; an insulation cylinder to support the bracket through an electric field relaxation shield; an insulated operating rod disposed in the insulation cylinder movably in the axial direction and an end thereof is connected to an actuator; and a link mechanism connected to other end of the insulated rod and transmits drive force from the actuator to the movable parts of the breaking sections, wherein the electric field relaxation shield is provided with out-side groove and in-side groove on the insulation cylinder respectively, and the out-side groove and in-side groove are formed openings at the link mechanism side respectively, and end of the in-side groove is extended to near the outer surrounding of the insulated operating rod. | 06-27-2013 |
| 20140231391 | SWITCHGEAR OPERATING MECHANISM AND SWITCHGEAR - A switchgear and an operating mechanism thereof which stably maintain a spring force by a shutoff spring, and reduce an opening time. The operating mechanism includes a main lever that rotates upon receiving the spring force by a shutoff spring released in a transition to a shutoff condition to move a movable contact apart from an opposing contact, and the main lever is linked with a sub lever fixed to a sub shaft rotatable around its shaft. The sub shaft is fixed with a latch lever with a roller attached to the tip thereof. The latch lever is prevented from rotating by a latch present on a movement trajectory of the roller. A weight is pushed against the latch in a separable manner, and the weight is pushed by an actuator to allow the latch to rotate, thereby being retracted from the movement trajectory of the roller. | 08-21-2014 |
| 20150136739 | Gas Circuit Breaker - The gas circuit breaker is made up of a fixed contact, a movable contact, a sealed tank having the fixed contact and the movable contact therein, an operating mechanism for driving the movable contact, and a mechanism unit for housing a link mechanism for connecting the operating mechanism with the movable contact . The operating mechanism is made up of an opening spring and a closing spring, cases for covering respective peripheries of those elastic bodies, a control mechanism for holding and freeing the driving force of the elastic body, and a link mechanism for conveying the driving force of the elastic body to the movable contact. The opening spring is laterally disposed in the axial direction between the link mechanism and the control mechanism. An integral flange is provided on an opening spring case and a closing spring case. | 05-21-2015 |
