The handle 50 in the leakage trip mechanism 40 can be used as a leakage indication, and is rotatably fixed to the first shaft 74 on the third outer casing 3. The spring 49 of the handle 50 is placed on the handle 50. The spring 49 has two arms and one arm. Acting on the handle 50, an arm acts on the outer casing 3 to function to reset the handle 50.

The handle 50 passes the U-shaped rod 51 to make the buckle 52 and the jumper 56 at the first trip surface 75 and the second trip surface 76. The latches are rotated, so that the movable link 54 rotates counterclockwise against the large torque of the torsion spring 70, and the striker 81 of the lower portion of the link 54 strikes the upper portion 80 of the reset lever 61, causing the reset lever 61 and the elastic spring 60 to rotate clockwise. The push rod 79 on the electromagnetic release 63 is pressed back to the initial position to complete the reset of the electromagnetic release 63; meanwhile, an arm 90 of the jumper 56 drives an arm 91 of the trip lever 59 to make the trip lever 59 Turn counterclockwise and reset.

当完成上述动作后，漏电脱扣机构 40处于合闸位置，见图 9a-9c。当互感器 62检测到漏电流时 , 互感器 62向电磁脱扣器 63发出动作信号，使电磁脱扣器 63上的推杆 79弹出，从而打击弹性簧片 60下端 83，打击力由簧片 60传到与之接触的脱扣杆 59上的凸起部分 41，使脱扣杆 59顺时针旋转，脱扣杆 59的上端 91打击到跳扣 56的下端 90 , 跳扣 56 受到逆时针的力后，第一脱扣面（上部脱扣面） 75随即与锁扣 52的第二脱扣面 76分离，漏电脱扣机构 40完成脱扣，在漏电脱扣机构 40脱扣的同时，连杆 54的折弯处 82会打击第九轴 65 , 第九轴 65和断路器的第一过电流保护极和第二过电流保护极的第一操作机构和第二操作机构的脱扣杆相连，从而使断路器脱扣。 When the above actions are completed, the leakage trip mechanism 40 is in the closing position, see Figures 9a-9c. When the transformer 62 detects a leakage current, the transformer 62 sends an action signal to the electromagnetic release 63 to cause the push rod 79 on the electromagnetic release 63 to eject, thereby striking the lower end 83 of the elastic spring 60, and the striking force is reed. 60 is transmitted to the raised portion 41 of the trip lever 59 in contact therewith, causing the trip lever 59 to rotate clockwise, the upper end 91 of the trip lever 59 hits the lower end 90 of the jumper 56, and the jumper 56 is counterclockwise After the force, the first trip surface (the upper trip surface) 75 is separated from the second trip surface 76 of the latch 52, and the leakage trip mechanism 40 completes the trip, and the trip unit 34 is tripped while the trip unit 40 is tripping. The bend 82 of the rod 54 strikes the ninth shaft 65, and the ninth shaft 65 is connected to the first overcurrent guard of the circuit breaker and the first operating mechanism of the second overcurrent protector and the trip lever of the second operating mechanism , thereby causing the circuit breaker to trip.

图 9a-9c中由于电磁脱扣器 63上的推杆 79弹出是瞬时的，在瞬间与手柄相连的 U型杆 51 来不及动作，因此与 U型杆 51相连的锁扣 52均处于暂时静止状态，而跳扣 56受到脱扣杆 59的冲力而发生逆时针转动。 In Figures 9a-9c, since the push rod 79 on the electromagnetic trip unit 63 is instantaneously popped, the U-shaped rod 51 connected to the handle is inaccessible in an instant, so that the lock 52 connected to the U-shaped rod 51 is temporarily stationary. And the jumper 56 is rotated counterclockwise by the impulse of the trip lever 59.

图 3a中的 38表示测试按扭 55位于上端面 101和侧面 108处。扭簧 57被固定在外壳 3上的轴 58上，其一臂 68穿过外壳 3与第二过电流保护极 7的第二接线端（进线端） 26在电气上相连。试验电阻 19被固定在第一过电流保护极 6内（见图 5 ) , 试验电阻 19的一引脚穿过外壳 2 , 在外壳 3的中上部、区域 28 (第一短路瞬动保护装置 28 ) 和手柄 50 (漏电指示手柄）之间的半孔型槽 66上固定（见图 7 ) 。试验电阻 19的另一引脚与第一过电流保护极 6的第一短路瞬动保护装置 28中的线圈 46在电气上相连，线圈 46通过软线 44从互感器 62 中穿出（第二短路瞬动保护装置 34以及线圈 47和软线 45的结构类似 ) , 与第一过电流保护极 6的第一接线端（出线端） 24点焊在一起。扭簧 57的另一臂 67与试验电阻 19 的一引脚在 69位置处形成一断口。 38 in Fig. 3a indicates that the test button 55 is located at the upper end surface 101 and the side surface 108. The torsion spring 57 is fixed to the shaft 58 on the outer casing 3, and an arm 68 thereof is electrically connected through the outer casing 3 to the second terminal (incoming end) 26 of the second overcurrent protection electrode 7. The test resistor 19 is fixed in the first overcurrent guard 6 (see FIG. 5), and a pin of the test resistor 19 passes through the outer casing 2, in the upper middle portion of the outer casing 3, the region 28 (the first short circuit instantaneous protection device 28) ) Fix it on the half-hole groove 66 between the handle 50 (leakage indicating handle) (see Figure 7). The other pin of the test resistor 19 is electrically connected to the coil 46 in the first short-circuit protection device 28 of the first overcurrent guard 6, and the coil 46 passes through the cord 44 from the transformer 62 (second The short circuit momentary protection device 34 and the coil 47 and the cord 45 are similar in structure, and are soldered to the first terminal (outlet end) 24 of the first overcurrent protection electrode 6. The other arm 67 of the torsion spring 57 forms a break at the 69 position with a pin of the test resistor 19.

当测试按鈕 55被按下时，测试按鈕下部的压柱使扭簧 57 的一臂 67 被按下，与放置在半孔型槽 66中的试验电阻 19的引脚相接触，使测试回路 22导通，形成测试漏电流，从而使漏电脱扣机构脱扣 40，断路器断开。 When the test button 55 is pressed, the press post at the lower portion of the test button causes an arm 67 of the torsion spring 57 to be pressed to come into contact with the pin of the test resistor 19 placed in the half-hole groove 66, so that the test circuit 22 is made Turning on, a test leakage current is formed, so that the leakage trip mechanism trips 40, and the circuit breaker is disconnected.

压簧 53紧紧箍在测试按扭 55的圆柱上，当漏电机构处于合闸状态时，压簧 53下部悬空；当漏电机构处于分闸状态时，压簧 53在跳扣 56上右侧的平台 77处对跳扣 56产生一个 £小的顺时针方向的复位力。图 10中漏电脱扣机构处于脱扣状态。其中的各个部件与图 8a-8c以及图 9a-9c中描述的类似，此处不再重复说明。 The compression spring 53 is tightly hung on the cylinder of the test button 55. When the leakage mechanism is in the closing state, the lower portion of the compression spring 53 is suspended; when the leakage mechanism is in the open state, the compression spring 53 is on the right side of the jumper 56. The platform 77 produces a small clockwise restoring force to the jumper 56. In Figure 10, the leakage trip mechanism is in a tripped state. The various components therein are similar to those described in Figures 8a-8c and Figures 9a-9c and will not be repeated here.
