产品型号及其含义 Product model and its meaning

结构特点及工作原理 Structural characteristics and working principle

产品外形结构见图1、图2，安装尺寸如图3所示。本环网柜是以空气为绝缘介质的，主要配装ZFN □ -10/630型真空负荷开关，主要方案有进线柜和出

线柜等。

1. 进线柜方案

柜内主回路有一台ZFN□-10/630 型真空负荷开关，它配装有隔离刀、酌情还配装接地刀所组成，三者共装在一个机架上，并互有联锁。因此可实现接

通母线、隔离、接地三个工位的操作，柜内还可灵活配装CT、PT等元件。

 2. 出线柜方案

柜内主回路有一台ZFN □-10/630型真空负荷开关和带撞击器的熔断器(有隔离开关的作用)及接地刀所组成，也可实现三工位操作，柜内还可灵活配

装 CT/PT和ZNO避雷器等元件，因此有时可省去计量柜。进、出线柜均配有与接地开关联锁的绝缘防护隔板，柜内各开关与隔板及柜门间采用机械联锁，并

达到“五防”要求，柜体外壳防护等级为IP2X。

The outline structure of the product is referred to as diagram 1 and diagram 2; the installation dimension is referred to as diagram3. This ring network type cabinet makes air as the

insulating medium,mainly assembled with ZFN □ -10/630 type vacuum load switch. And there are two cabinet schemes - incoming cabinet and outgoing cabinet.

1. Incoming cabinet scheme

There is a ZFN □ -10/630 type vacuum load switch on the main circuit inside the cabinet with isolating knife, and grounding knife conditionally. The three of them are all installed in one machine stand and there are interlocks among them, so that it is realized to connect the operation of three working stations of bus, isolation and grounding. Inside the cabinet the components such as CT, PY are available.

2.Outgoing cabinet scheme

ZFN □ -10/630 type vacuum load switch, fuse with striker (used as isolating switch) and grounding knife on the main circuit inside the cabinet, and the three working stations operation can be realized. Inside the cabinet the components such as CT/PT and ZNO arrester are available, so the metering cabinet can be omitted. Inside the incoming cabinet and outgoing cabinet, there is insulating protecting baffle interlocked with grounding switch. And inside the cabinets ,the mechanical interlocks are adopted between each switch and baffle  as well as the cabinet door with the requirement of “five-prevention” and IP2X of the protection degree of the cabinet enclosure.

吊运、安装、调试和熔断器的更换 Hoisting, installation, commissioning and replacement of fuse

1. 吊运

吊运前按规定进行开箱前的检查。柜体吊运时按作业标记要求，小心轻放、防震等。

2. 安装

开箱后，检查柜体及柜内元件是否完好，动作是否正常，是否受潮等，在确认无误后，方可进行安装。

3. 调试

如发现柜内元件达不到其技术要求或联锁不到位时，需按下列过程调试：

(1) 对负荷开关和接地或隔离开关，可通过调节拉杆长度和变换拉杆与操作杆角度和位置来达到技术要求。

(2) 若有联锁不到位时，可微调相应的操作拉杆长度来改变联锁孔的位置，使联锁到位。

4. 更换熔断器

必须严格按停电顺序操作，将负荷开关分闸，然后打开熔断器到隔离位置，并将接地开关合上，在插入绝缘防护隔板后，柜门方可打开，才能进行更换熔断器。

1. Handling

Before handling, undertake check before opening the cabinet according to the regulations. When the cabinet is handling delivered, it’s a must to operate according to the operation marking demands.

Handle with care and without shake.

2. Installing

After opening the cabinet, check whether the cabinet body and the components inside are good, whether theyworknormally, and whether they are moistened. Only after definite confirmation can the installation be undertaken.

3. Debugging

It’s necessary to have a debugging according to the following steps if the components inside the cabinet don’t meet the technical requirements or the interlocks don’t locate well:

(1) For the load switch, grounding switch or isolating switch, you can make them meet the technical demands by adjusting the drag rod length, changing the angle and position of drag rod and operating rod.

(2) If there is any interlock that doesn’t locate well, you can make it locate by fine adjusting relevant operating rod length to change the position of interlock hole.

4. Fuse replacing

It must operate strictly according to the sequence ofpoweroff. First, turn off the load switch, turn on the fuse tothe isolatingpositionandthenturnonthegrounding switch. Only after plugging the insulating protecting baffle can the cabinet door be opened and can the fuse be replaced.

使用与故障处理 Use and troubleshooting

1. 使用

请务必严格按照下列步骤操作，否则易造成损害。

(1) 负荷开关的操作顺序

a 合闸：当负荷开关处于分闸状态时，将操作手柄插入负荷开关操作孔内顺时针转动(约180度)，使其合闸。

b 分断当负荷开关处于合闸状态时，可由手动脱扣按钮或脱扣电磁铁操作使负荷开关分闸，对配有带撞击器的熔断器的负荷开关，熔断器熔断后，其撞击器也可使负荷开关分闸。

(2) 停电操作顺序

a将负荷开关分闸，使它与隔离和接地开关之间的联锁解除。

b 将操作手柄插入隔离和接地开关操作孔内，按顺时针方向转动(约90度)，隔离刀被打开。

c 再按顺时针方向转动(约90度)后，接地开关快速闭合。

d 插入绝缘隔板，使门联锁解除。

e 开门检修。

(3) 送电操作顺序

a 关闭柜门。

b 抽出绝缘隔板，柜门锁住。

c将操作手柄插入隔离和接地开关操作孔内，逆时针转动( 约90度)，使接地开关分断。

d 对负荷开关进行操作，合闸送电。

2. 故障处理

环网柜在工作过程中，如果出现紧固件松动，机械部分润滑不良，真空灭弧室真空度下降等故障，在停电后采用紧固、加润滑剂、打耐压等方法来检查和消除以上故障。

1. Operation

Please operate strictly according to the following steps, otherwise some damage may be caused.

(1) Operating sequence of load switch

a. Switch-on: When the load switch stays on, plug the operating handle into the operating hole of the load switch and turn it clockwise (about 180° ) to make it stay on.

b. Switch-off: When the load switch stays on, manually operate the tripping button or the tripping electromagnet to make the load switch stay off. For the load switch with fuse striker, after the fuse is fused, the striker can make the load switch stay off.

Operating sequence of power off

d. Plug the insulating baffle to unlock the door interlock.

e. Open the door and maintain.

(3) Operating sequence of power transmission

a. Close the cabinet door.

b. Extract the insulating baffle and lock the cabinet door.

c. Plug the operating handle into the operating hole of the isolating and grounding switches and turn it anticlockwise (about 90° ) to turn off the grounding switch.

d.Operate the load switch and turn it on to transmit the power.

2. Fault treatment

During the operation of the ring network type cabinet, if there is any fault,such asloose fasteners, bad lubrication of mechanical parts and reduced vacuum degree in the vacuum interrupter, etc. After the power off, check and remove the faults by fastening, adding lubricant and adding withstand voltage, etc.
