Switch for gas insulated switchgear Full Description BACKGROUND: This invention relates to a switch for a gas insulated switchgear (GIS) and in particular relates to a GIS switch It can act as a disconnector switch and earthing switch with one © operation to improve operation efficiency and increase space utilization Gas insulation switchgear (GIS) switch includes in particular devices such as ccircuit breaker earthing switch a )| ¢ disconnector switch ¢ current transformer ; main bus bare etc.; An earthing a circuit mechanical switching device 0 is for the purpose of switching with earthing switch and said earthing switch of time in the designated time period current flow The current sshort cirouit, such as a normal short circuit, an abnormal condition, and the aforementioned disconnecting switch is merely a switching device used to disconnect the switching switch of a charged circuit. .charged circuit Yo etc.; “moving contact and fixed contact through a contact such as a fixed contact

Ja that allows current to flow in this way. And on any contact system and the contact system is not one of its functions Lill (GIS), the transfer switch for a gas insulated switchgear switches to ground and disconnects at the same time; And on that; There is a related problem

© drawback of inconvenient operation that occurs with .separately operating and also; As each key has a specific operating function; They take up a huge void.

General description of the invention

This invention solves the aforementioned problems as it aims to operate the disconnector switch and the earthing switch by a single operation so that a transfer switch is prepared for a gas insulated switchgear (GIS) ) which improves operation and increases -space-saving

01 In order to achieve the aforementioned objective, this invention includes the following configuration. A switch for a gas insulated switchgear (GIS) switchgear of this invention includes:

housing And the switch unit conversion unit between the contact of the switch connected to the earth

switch contact 0 and the contactor switch contacte Joaldll which is inside said housing; It allows selective contact with back-to-back shuttling between the grounded transfer switch contact and the disconnected transfer switch contact;

It is preferable that the aforementioned switch unit include: say a body prepared inside the housing ¢ a contact bar installed in said body and an axially sliding ‘axially’

with a selection bar ¢ embedded at one end of said contact bar”; For sliding ¢contact bar and ground contact bar protruding above said contact bar. It is preferable that the aforementioned contact bar be placed parallel to the contact hole of the disconnector switch contact. It is preferable that the aforementioned earthing bar 1 be placed parallel to the hole Earth switch contact. das preferably »; That the aforementioned earthing switch is in contact with the contact of the disconnector switch contact during ascending .Yo and according to this present invention; The disconnector switch and the earthing switch are operated by a single operation, which has the effect of improving the operating process and increasing the space-saving. 1 BRIEF EXPLANATION OF DRAWINGS Figure 1 is a transfer switch cross-section of a gas insulated switchgear (GIS) switchgear of the present invention. Figure ¥ is a perspective view of the switch unit shown in Figure 1. 70 Figures FF and; They are two operational figures showing the operation status of a bypass switch of a gas insulated switchgear (GIS) switchgear box according to this invention.

C Lad follows; Preferred embodiments of this invention will be explained in detail with reference to the accompanying drawings. The embodiments of this invention can be modified in its various forms; The scope of this invention should not be limited to the embodiments explained later. and such embodiments are herein prepared for the particular interpretation of this invention to persons with ordinary experience in the art. and on © it; The shape of each component shown in the drawings can be oversimplified for clarity. As shown in Figure 1; the switch of a gas insulated switchgear (GIS) box (01) of this invention includes the housing “(VY +) housing (VY) switch unit and earthing switch contact 0 (+¥ 1)” disconnector switch contact (001) and earthing switch (Yo +) earthing switch (111) housing. A cylindrical shape where both axial sides ¢ are opened and a supporting member (111) is fixed on one side of an axial central part Yo switch unit mentioned (+VY) comprising a (YY) body affixed to one side of said support member (111) and a ¢(1Y£) contact bar affixed to the body; and a test rod (17) selection bar for sliding the contact bar (VY £) contact bar to the left and right of the body; and the aforementioned body (111) is cylindrical in order that the second guide slot is 00 (17) second guide It passes axially through it, and while it is in contact with the aforementioned second guide hole (771), the first guide hole (177) is formed so that it passes vertically with respect to the second guide hole (VY).

-- said contact bar (VV) having a shape corresponding to the shape of the second pilot hole (11); and a vertical bar (VY0) extending on one side over a couter surface and the ground contact bar earthing bar constructed to extend and protrude on one side of the vertical rod end (VY0) and on the outer surface; pin axis (VY) oe formed laterally protruding vertical (ila) with the vertical rod cling L(V YO) the vertical rod (1Y0) can be parallel to the axis of the screw but preferably to be biased to one side. In the said selector rod o(V YA) an insulator, a pin guide hole (175) 0 is formed in the form of a slit: 16; rotates around an axis (1"8a). Earthing switch contact (011) is in the form of a rod; a hole (11) is formed so that it passes through the lower part. The contact of the said disconnector switch contact (060) is supported by a support rod (V €)) supporting bar A contact hole (07) is formed at V0 on one side of the body and a Transfer Switch Ground (VEY) contact is formed at a position where it meets the contact hole (VEY) at the right corner . Said earth transfer switch (104) consists of a contact rod (VO) inserted and moved through the body (101) and in connection with the contact relation of this invention” at one side above the housing “Yo” where the support rod is fitted; the orifice 171 leads to the housing ¢ and a VY earthing switch contact is inserted such that the eda of the upper end protrudes outwards.

Cull at (VY) earthing switch contact opposite (VEY) and at that time; The contact hole (161) is to be toward the inserted earthing switch (161). F) Contact bar The lower part of the housing is connected to the lower surface of the housing so that it is vertical with the installed disconnector switch contact. (171) A switch unit associated with the supporting member (111) 0. At that time, it is required to pay attention to the (YY) switch unit so that the earthing bar (177) is directed towards the ¢(VY+) earthing switch contact and the (VY £) contact bar is directed towards the -(Y £Y) contact hole and at the same time; the switch unit 171 switch contact and pin axis (VY€) protruding in one side of the body (1,1) after inserting the contact rod (VYY) axis Vo to protrude the vertical rod (VY) at the guide hole First (177) first guide hole The selection bar is placed into the (YY) pin guide hole in the pin (77" 1), which protrudes to the side of the body; so that the contact bar can slide axially according to the angle of the test rod 0 at the selection and at that time; While it is not illustrated in the drawings; It is generally known that when one side of the body; There is a slot (not shown) in which the input and guide pin axis (VYV) are formed.
