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.
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.
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.
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.
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.
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.

Mount with drawable circuit breaker into the panel: Before moving the withdrawable circuit breaker into the compartment, it is necessary to check the withdrawable circuit breker wheather in good condition, wheather any part or sundries are left inside the mechanism box and compartment. Put the withdrawable circuit breaker on the transfer truck and lock it well. Push the transfer truck up to the fornt of the switchgear and lift it to a proper height. Insert the front positioning lock plate of the transfer truck into the slot of the compartment partition and lock the transfer truck and the compartment body together. Open the locking hook of the withdrawable circuit breaker and push it into the compartment smoothly and steadily and lock it well. After the locking of withdrawable circuit breaker and compartment body is confirmed, unlock and disconnect the transfer truck from the compartment body and move it away.
Operation of the withdrawable circuit breaker inside the compartment:
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.
