Description

[0001] The present invention relates to a gas insulated switchgear,

The present invention relates to a gas insulated switchgear, and more particularly, to a gas insulated switchgear having a compact configuration that meets various requirements of a user and can reduce the generation of driving force and metallic foreign matter by individualizing the operation of the disconnecting switch and the grounding switch.

Generally, the gas-insulated switchgear is provided with a cut-off portion by forming a constant internal space inside the case, and filling the internal space with an insulating gas such as SF ₆ , which is an inert gas excellent in dielectric strength, .

Such a gas insulated switchgear includes a circuit breaker (CB) that functions to open or close a load in a transmission, distribution system or an electric circuit, or to interrupt a current (load current) when an accident such as a grounding or a short circuit occurs, A grounding switch for removing the residual voltage and current remaining in the switching device for maintenance inspection of the gas insulated switchgear and a ground contact switch for disconnecting the power supply part from the power supply for checking and repairing the device, And a disconnecting device which must have the capability of opening and closing the charging current or the loop current of the line or the bus line.

Further, the opening and closing operation of the disconnecting switch is performed when the circuit breaker or other switch is in a disconnected state, that is, when the switch is in a no-load current state, and is used for circuit isolation or connection change for checking a line or the like.

Also, a method of implementing a grounding switch and a disconnector in a single assembly is called a 3-position switchgear or a 3-way switchgear and implements a mechanical interlock between a grounding switch and a disconnecting switch .

In the conventional gas insulated switchgear with three-position switchgear, a lever, a link, and a disconnector-grounding switch mover are connected to a rotating shaft inside the enclosure by a pin to simultaneously move the disconnector-grounding switch mover during operation. And the rotation of the lever is converted into a rectilinear motion of the mover, and the force always acts at a constant angle with respect to the moving direction of the mover due to the rotation of the lever.

Therefore, by simultaneously driving the mover-to-ground contactor's mover, even if only the operation of either the disconnector side or the earthing switch side is required, the mover is driven at the same time, so that the driving force also increases with unnecessary movement, Thereby increasing the possibility of occurrence of an insulation accident.

 Openings 210 corresponding to the disconnectors DS and the grounding switches ES may be formed on both sides of the main body 200, respectively. Here, the disconnector DS and the grounding switch ES side opening 210 may be arranged at various angles? Depending on the structure within a range that does not cause interference with the operation of the device.

The driving gear 300 is mounted on the shaft 310 so as to be rotatable in the main body 200 in the form of a pinion gear and an external manipulator for transmitting driving force to the shaft 310 Not shown).

That is, the driving gear 300 is selectively moved in either direction so as to be positioned in either the disconnector DS, the earthing switch ES direction, or the neutral position (disconnecting all the contacts) by the driving force of the external manipulator Rotate.

In other words, the rotation direction of the driving gear 300 is determined by the operation of the external manipulator, and the rotation is selectively performed to the disconnector DS side or the earthing switch ES side by the determined rotation direction.

Of course, when disconnecting both the disconnecting device DS and the grounding switch ES, the driving gear 300 is rotated to the neutral position where no connection is made. 7, the first driven gear 400 is installed on the shaft 310 so as to be engaged with the drive gear 300. The first driven gear 400 is rotatably supported by the main body 200, Side opening portion 210 of the disconnecting device (DS) side. The first driven gear 400 rotates in a direction opposite to the rotation direction of the drive gear 300 because it has the form of a pinion gear.

The first rack gear 420 is meshed with the first driven gear 400 and moves in one direction along the rotation direction of the first driven gear 400, Connected or disconnected. In other words, it is connected to or disconnected from the contact of the isolator DS via the isolator (DS) side opening 210.

Here, the first rack gear 420 and the second rack gear 520 are assembled to the disconnector DS or the disconnecting mover 600 of the earthing switch ES and the grounding mover 700, respectively desirable.

 On the other hand, the second driven gear 500 is provided with a shaft 310 to be engaged and rotated at the side of the earthing switch ES with respect to the driving gear 300. The second driven gear 500 is connected to the earthing switch ES- (210).

The first rack gear 420 and the second rack gear 520 described above can be arranged at various angles (?) According to the structure so that they do not interfere with each other. For example, when the first rack gear 420 is installed vertically, the second rack gear 520 may be installed horizontally.

The first driving gear 300 may include a first guide member 320 formed between the first driven gear 400 and the second driven gear 500 and having a circumferential surface with a radius of rotation.

The first rack gear 420 and the second rack gear 520 described above are disposed so that one end of each of the first rack gear 420 and the second rack gear 520 is separated from the contacts of the disconnector DS and the earthing switch ES when the driving gear 300 is in the neutral position. .

At this time, it is preferable that both ends of the first guide member 320 in the rotational direction (longitudinal direction) are closely contacted with the inner circumferential surfaces of the second guide member 410 and the third guide member 510.

The actuating device 100 of the present invention described above drives only one disconnector DS and one earthing switch ES and the other is fixed so that the disconnector DS driving device and the earthing switch ES driving device It can be driven independently. In addition, it is possible to maintain the neutral position where the connection between the disconnecting switch DS and the earthing switch ES can be disconnected, and all three positions can be driven by one actuator.

As a result, it is possible to drive both the isolator (DS), the earthing switch (ES), or the neutral position with a single actuator, the structure is simple, the rotary motion of the lever is changed to linear motion by the gear, ) Side and the disconnector (DS) side, it is possible to reduce the number of operation and reduce the generation of metal foreign matter, prevent the accident of the high voltage circuit breaker, and improve the quality.
