Trolley 1.The framework of trolley is bent and welded by the high-grade sheet steel. The trolley can be divided into the trolley of circuit breaker, separation trolley, trolley of voltage transformer and trolley of lightning arrester and so on according to the purpose. Trolley of same specification can be interchangeable. .The pushing device of trolley consists of leading screw nut pushing mechanism, overrunning clutch and interlocking mechanism and so on. The leading screw nut pushing mechanism can operate easily to make the trolley move between the testing position and working position. The elf-locking property of leading screw nut can be utilized to lock the trolley at the working position reliably and prevent the accident from play of trolley due to action of

electrical force. The overrunning clutch will enable the operating shaft to separate from the lead screw automatically and the operating shaft runs idly when the trolley moves back to the testing position and advances to the working position, and thus avoid damage to the construction.

The guide rail is installed at the bottom of circuit breaker compartment to function as the correct guidance for the smooth operation of trolley between the testing position and working position. The valve is installed in front of the contact box. The upper and lower valve opens automatically during the process that the trolley moves to the working position from the testing position. When the trolley moves oppositely, the valve closes automatically to form the effective separation. The upper and lower valve can be locked while overhauling so that it can ensure that the maintainer will not contact the charged body. The trolley can be operated when the cabinet door is closed. The emergency switching-off operating hole is installed at the door face for manual switching off. The position where the trolley is located at and on/off position indicator of circuit breaker as well as energy-storage state of switching-on spring can be observed through the observation window on the door.

.There are operating button with obvious prompting sign or KK changeover switch and prompting sign on the analog drawing board from the client (e.g. red/green drawing) on the door of relay instrument compartment. They are cooperated to prevent the circuit breaker from wrong switching on and off.

2. 断路器手车只有处在试验或工作位置时断路器才能进行分合闸 操作,而且断路器只有处在分闸位置时手车才能从实验位置推向工 作位置 ,或者从工作位置退到实验位置 ,从而可靠的防止带负荷分 合隔离插头.
The switching-on/off operation of circuit breaker can be done only when the trolley of circuit breaker is located at the testing position or working position. Moreover, the trolley can be pushed to the working position from the testing position or returned back to the testing position from the working position only when the circuit breaker is located at the switching-off position. Thus, it prevents switching on and off isolating contact with charge.

手车只有在实验位置接地开关才能进行合闸操作,防止带电合隔离开

关.
3.The switching-on operation of grounding switch can be done only when the trolley is located at the testing position to prevent switching on the grounding switch with charge.

接地开关处于合闸状态,手车不能推到工作位置,防止带接地开关 合闸.
4.When the grounding switch is located at the switching-on state, the trolley cannot be entered into the working position to prevent switching on the grounding switch.

接地开关不合则开关柜后门开不了;反之,后门不关则接地开关不 能分闸,从而防止误入带电间隔.
5.The rear door of switch cabinet cannot be opened if the grounding switch does not switch on. On the other hand, the grounding switch cannot switch off if the rear door is not closed. Thus, it can be prevented that the charged compartment is entered wrongly.

不装接地开关的断路器柜,母线分段柜和母线设备柜等还需要相 应的电磁锁(或程序锁)配合完成全部防误功能.
6.For the circuit breaker cabinet and subsection cabinet of bus as well as bus contact cabinet and so on without installation of grounding switch, the corresponding electromagnetic lock (or program lock) is needed to cooperate and finish all mistake-prevention functions.

手车只有在试验位置二次插件才能插入或拔出,手车在工作位置 二次插件被锁定拔不出.
7.The secondary plug-in unit can be inserted in or plugged out only when the trolley is located at the testing position. The secondary plug-in unit is locked at the working position and it cannot be plugged out if the trolley is located at the working position.

between the trolley and cabinet body.

2. 电缆室内单独设有 5X40(mm2)接地铜排,此铜排能贯穿整个排列与 柜体接触良好,供直接接地元件使用,从而使整个柜都处于良好的 接地状态之中.
.The 5×40(mm2) copper grounding bar is installed in the cable compartment individually. This copper bar can be through the whole arrangement and contacts with the cabinet body well. It is provided to the direct grounding element for its use. Thus, the whole cabinet is located at the good grounding state.

八 泄压装置 pressure relief device 在断路器式,母线道和电缆室设有泄压通道,各泄压盖板的一端用 金属螺栓固定 ,另一端用塑料螺栓固定 ,当故障时 ,内部高压气体能容 易地将泄压盖板冲开释放压力,以确保操作人员和开关设备安全.

The pressure relief devices are equipped on the top of the circuit breaker compartment, busbar compartment and cable compartment. In case fault arcing is occurred inside these three compartments, the special sealing ring seals the front door completely, and along with the increase of the gas pressure inside the compartment , the top mounted pressure relief metal cover plate will open automatically to release pressure and the high temperature gas to ensure operator and switchgear in safe condition. 九 电压显示装置 charge indicator 开关柜装设有监视一次回路带电状态的带电显示装置 ,该装置不 但可以显示高压回路带电状态,而且可以与电磁锁配合实现强制闭锁 手柄,从而提高产品的防护性能.

The charge indicator is in talled in the switchgear to monitor the operation of the primary circuit. it consists of high sensor and indicator which are connected together by external wiring. This device is used to monitor whether the high-voltage circuit is in live. And it also can be equipped with electrical magnetic lock to ensure the front and back door not be opened when there are power on. So that operators don’t make such mistakes as close earthing switchgear in live or access the compartments in live. 十 防凝露措施 condensation and corrosion prevention 为了防止在高温度或温度变化较大的气候环境中产生凝露而带 来的危害,可在断路器室和电缆室分别装设加热器, To prevent switchgear form undesirable condensation due to high humidity or big change in climate condition, heaters could be added inside switchgear which can be controlled by humiture probe.

十一 操作程序 operation procedures 制作 KYN61-40.5 型金属封闭开关设备设计有保证开关柜各部分 操作程序正确性的联锁,但操作人员对该型开关柜各部分的操作仍应 严格按照有关操作规程和本《说明书》中的要求进行 ,不应在操作受 阻时不加分析地进行操作,可能容易造成设备损坏甚至引起事故. Operator must operate the switchgear in accordance with the related operating procedures and this technical document. Any optional

当手车在试验位置后即将二次插件插好,此时对断路器进行操 作试验 ,若还要继续操作 ,首先必须将所有的柜门关闭并确认断路 器处于分闸状态 , 然后打开推进机构操作孔挡析插入操作摇把 , 并 以顺进针方向转动,使手车向前移动,直至超越离合器 ,起作用使操 作轴空转,此时主回路已接通,手车已处于工作位置(热备用状态),可 通过控制回路对其进行和分闸操作. 若将手车从工作位置退出时,则以逆时针方向转动摇把,手车 向后移动 , 直至超越离合器起作用使操作轴空转 , 手车便退至试验 位置,此时主回路已断开,活门已关闭(处于冷备用状态).
After the withdrawable circuit breaker is moved inside the compartment by transfer truck and the withdrawable circuit breaker is in sconnected/testing position, first insert the secondary plug of the auxiliary circuit to put withdrawable circuit breaker into ready operating status. With power connected, the testing position indicator on the low voltage compartment will light, and at that time, an electrical operating test could be made without connection of the main circuit. For further operation, it must close all compartment doors, insert the keys to lock the doors and confirm the circuit breaker at its opening condition . Then insert the hand crank into the operating hole of the middle panel to turn it clockwise till the crank is obstructed obviously and hear a clear switchover sound of the auxiliary switch. In the meantime, the service position indicator on the low voltage compartment will light and then remove the hand crank. At this time, the main circuit is connected with power and the withdrawable circuit breaker is at its service position, operator can open or close the withdrawable circuit breaker via control circuit. To withdraw the withdrawable circuit breaker from its service position, it should first confirm the withdrawable circuit breaker at its opening state , insert withdrawable the circuit breaker hand crank and turn the hand crank anticlockwise till the crank is obstructed obviously and hear a clear switchover sound of the auxiliary switch. At that time, the withdrawable circuit breaker returns back its testing position, the main circuit is open completely and the shutters are closed.

3. 手 车 退 出 柜 外 ; Take the withdrawable circuit breaker out of the
compartment:
