再次利用手动拐臂置断路器各极本体于分闸位置将撬杆插在手动拐臂并安装在一

Use the manual arm again to place each pole body of the circuit breaker in the opening position. <br>Insert the pry bar into the manual arm and install it on the transmission shaft of the one-pole circuit breaker body. The opening and closing of each pole body of the circuit breaker should be able to close and close smoothly. Open the circuit breaker without obvious sticking. After passing the test, place the circuit breaker in the lowest open position. <br>Install the transmission arm, pin shaft and the manual pry bar provided, and then perform the slow closing operation. Use a multimeter to monitor whether the circuit breaker of each pole is turned on. When it is turned on, measure the corresponding distance and make a record. Calculation of contact travel of circuit breaker. <br>Use the manual arm again to place each pole body of the circuit breaker at the bottom position of the circuit breaker. Install the transmission arm according to the marked point position and connect it to the joint of the buffer. Rotate the adjustment joint by hand to pre-tighten it, and then use a wrench to turn it 1 turn. , and finally tighten the nuts at both ends of the adjustment joint to restore the outer rain cover. <br>Install the opening and closing indicator board correctly.

Re-use the manual crank arm to position the circuit breaker poles at the opening position<br>Insert the pry bar into the manual crank arm and install it on the transmission shaft of the one pole circuit breaker body. When opening and closing the circuit breaker bodies at each pole, they should be able to smoothly close and open without obvious jamming. After passing the test, place the circuit breaker in the fully open position.<br>Install the transmission crank arm, pin shaft, and the manual lever provided with the machine, and then perform a slow closing operation. Use a multimeter to monitor whether each pole of the circuit breaker is connected, measure the corresponding distance when connected, and keep a record for calculating the contact stroke of the circuit breaker.<br>Once again, use the manual lever arm to position the circuit breaker at the bottom of the opening position. Install the transmission lever arm according to the marked position and connect it to the joint of the buffer. Rotate the adjustment joint by hand to pre tighten it, then use a wrench to turn it for 1 turn. Finally, tighten the nuts at both ends of the adjustment joint and restore the outer rain cover.<br>Install the opening and closing indicator correctly.

Once again, the manual crank arm is used to place each pole body of the circuit breaker in the opening position.<br> Insert the pry bar into the manual crank arm and install it on the transmission shaft of a pole breaker body, and open and close each pole body of the circuit breaker, which should be able to switch on and off smoothly without obvious jamming. After passing the test, put the circuit breaker in the switch-off position.<br> Install the transmission crank arm, pin shaft and manual pry bar provided randomly, and then carry out slow closing operation. Monitor whether the circuit breakers of each pole are connected with a multimeter, measure the corresponding distance when connected and make records for the calculation of the contact stroke of the circuit breakers.<br> Once again, use the manual crank arm to place each pole body of the circuit breaker in the switch-off bottom position, install the transmission crank arm according to the marked position and connect it with the joint of the buffer, rotate the adjusting joint by hand to preload it, then turn it with a wrench for one turn, and finally tighten the nuts at both ends of the adjusting joint to restore the outer rain cover.<br> Install the opening and closing signs correctly.
