Gas insulated metal enclosed switchgear

产品的结构特点/Structural features of the product

● 柜体
柜体由2mm敷铝锌板折弯后组装而成，起支撑主气箱并对开关柜操作机构，外部元件进行防护的作用。柜体前面板上有—次方案模拟图、开关状态指
示、操作孔等。
● 气箱
气箱为3mm 304不锈钢板焊接，内装有开关设备的一次带电部件，气箱采用焊接机器人焊接，通过等压抽真空和氦检漏技术，保证产品的密封性。箱 体上
装有密度继电器以观测箱体内气体压力，箱体还装有防爆膜片，当发生内部电弧故障时，防爆膜片破裂，释放故障气体，保证用户最小损失。
● 负荷开关/接地开关
负荷开关分为二工位（合闸-分闸）和三工位（合闸-分闸—接地）两种结构。
接地开关：接地开关和负荷开关之间实现联动操作，设置有机械联锁，确保安全操作。
真空断路器／隔离开关：断路器方案分为V方案和CB方案，V方案为隔离开关和断路器为一体式结构，断路器位于母线侧;CB方案为真空断路器及其
操作机构为独立单元,断路器位于电缆侧。
● 操动机构
三工位负荷开关操动机构：
○T型：“合”、“分”、“接地”均为手动操作，用于电缆进出线柜；
○TR型：与T型类似，不同之处在于手动合闸操作中已对弹簧进行储能以备分闸，可由旋钮、分闸线圈、熔断器或继电器来控制分闸,用于组合电器。
○TM型：与T型类似,增加了电动。“合”、“分”操作。
○TRM型：与TR型类似，增加了电动“台”、“分”操作。
真空开关，真空断路器柜的三工位隔离开关操动机构：
○T1型：配在V方案断路器柜上。
○T2型：配在CB方案断路器柜上。
真空开关，真空断路器撰动机构：
○ 真空开关，真空断路器操动机构句适用于断路器柜V方案和CB方案;
● 熔断器
在F柜中，熔断器先安装在熔断器支座上,然后再插入熔断器绝缘筒中。
三个品字形分布的熔断器绝缘筒位于气箱内并与气箱很好的密封。当熔断器支座插入绝缘筒后，绝缘筒与外界隔离，能够保证不受外界污秽的影响，熔
断器任意—相熔断都能引起撞针触发，带动快速联动机构实现负荷开关分闸。

● Cabinet
The cabinet is assembled by bending 2mm aluminum-zinc plate, which supports the main air box and protects the operating mechanism and external
components of the switchgear. The front panel of the cabinet has a simulation plan and switch status.
Show, operate holes, etc.
● Air box
The gas box is welded with 3mm 304 stainless steel plate, and has one live parts of the switchgear. The gas box is welded by welding robot, and the sealing
of the product is ensured by equal pressure vacuuming and helium leak detection technology. The box is equipped with a density relay to observe the gas
pressure inside the box. The box is also equipped with an explosion-proof diaphragm. When an internal arc fault occurs, the explosion-proof diaphragm
ruptures and releases the faulty gas to ensure the user's minimum loss.
● Load switch / grounding switch
The load switch is divided into two structures: the two-position (closed-opening) and the three-station (closing-opening-grounding) structure.
Grounding switch: The interlocking operation between the grounding switch and the load switch is provided with mechanical interlock to ensure safe
operation.
Vacuum circuit breaker/isolation switch: The circuit breaker scheme is divided into V scheme and CB scheme. The V scheme is an integrated structure of
the isolating switch and the circuit breaker, the circuit breaker is located on the busbar side; the CB scheme is a vacuum circuit breaker and
The operating mechanism is a separate unit and the circuit breaker is located on the cable side.
● Operating mechanism
Three-station load switch operating mechanism:
○T type: “combination”, “minute” and “grounding” are all manual operation, used for cable entry and exit cabinets;
○ TR type: similar to the T type, the difference is that the spring has been stored in the manual closing operation for the opening, and can be controlled by
the knob, the opening coil, the fuse or the relay for the combination of electrical appliances.
○TM type: Similar to the T type, electric is added. "合", "分" operation.
○TRM type: Similar to the TR type, the electric "stage" and "minute" operations are added.
Vacuum switch, three-station isolation switch operating mechanism of vacuum circuit breaker cabinet:
○T1 type: It is equipped with the V scheme breaker cabinet.
○T2 type: It is equipped with CB scheme breaker cabinet.
Vacuum switch, vacuum circuit breaker writing mechanism:
○ Vacuum switch, vacuum circuit breaker operating mechanism sentence applies to circuit breaker cabinet V scheme and CB scheme;
● Fuse
In the F cabinet, the fuse is first mounted on the fuse holder and then inserted into the fuse insulation barrel.
The fuse-insulated cylinders of the three-shaped distribution are located in the air box and are well sealed to the air box. When the fuse holder is inserted
into the insulation tube, the insulation tube is isolated from the outside to ensure that it is not affected by external contamination.
Arbitrary break-phase fuse can cause the trigger to trigger, and drive the quick linkage mechanism to realize the load switch opening.
