[0040] The mounting plate 10 is fixedly mounted at the inner center of the frame 1 , a circuit breaker is fixedly mounted on the mounting plate 10 , and the mechanical operating handle 7 is connected to the circuit breaker.

[0041] A primary plug-in 11 is fixedly installed at the lower left end of the rear wall of the frame 1, and the primary plug-in 11 is arranged through the lower left side of the rear wall of the frame 1;

[0042] A one-time outlet plug-in 12 is fixedly installed at the lower right end of the rear wall of the frame 1, and the one-time outlet plug-in 12 is arranged through the lower right side of the rear wall of the frame 1;

[0043] A secondary plug-in 13 is fixedly installed above the primary output plug-in 12 .

[0044] A closing and opening relay 14 is fixedly installed on the right end of the position relay 6;

[0045] A door lock 16 is fixedly installed at the center of the right side of the front wall of the door panel 2.

[0046] Rollers 15 are rotatably connected to the left and right sides of the frame 1 .

[0047] Working principle: Frame 1 has four positions, working position, experimental position, separation position and removal position;

[0048] The primary plug-in 11 and the secondary plug-in 13 of the frame 1 are both in a plug-in connection state. In this position, the frame 1 is locked by the propulsion mechanism 4 or the interlocking mechanism, but the circuit breaker in the frame 1 can be opened and closed;

[0049] There is a mechanical interlock when the frame 1 moves. This interlock mechanism sets an interlock procedure for the opening and closing of the circuit breaker and the movement of the frame 1. The interlock mechanism requires that the frame 1 can only be moved when the circuit breaker is in the open state, that is, the frame 1 can only be moved out when the circuit breaker is disconnected from the power supply;

[0050] The incoming and outgoing wires of frame 1 use connectors of the same specification with different numbers of pieces according to the current size. The structure of frame 1 is closely related to the performance of electrical interlocking. Frame 1 cannot be pulled out in the closed state, and frame 1 cannot be closed in the pulled-out position. After frame 1 is pulled out, the primary part is completely blocked by the insulating parts and cannot be touched by hand. A padlock is placed on the operating mechanical operating handle 7, thereby ensuring the strictness of the operation and the personal safety of the operator;

[0051] The frame 1 is assembled by splicing to form drawer units with different structures and functions, and has standardized modules such as protection function, operation function, conversion function, control function, adjustment function, measurement function and indication;

[0052] By rotating the mechanical operating handle 7, the circuit breaker is powered off, and then the user closes the door panel 2 and locks it through the door lock 16. By pressing the button 17, the position relay 6 is in the separated position, and the frame 1 is inserted into the device, and the primary input plug-in 11, the primary output plug-in 12 and the secondary plug-in 13 are connected to the device respectively, and the frame 1 is completely pushed into the device. The button 17 is released, so that the position relay 6 is in the working position, and the mechanical operating handle 7 is rotated to power on the circuit breaker, and the frame 1 is locked. Then, the closing and opening relay 14 is closed, so that the primary input plug-in 11, the primary output plug-in 12 and the secondary plug-in 13 are locked with the device, and secondary protection is performed to prevent the frame 1 from being separated from the device due to misoperation, which may cause danger;

[0053] After the use of the frame 1 is completed, first, the circuit breaker is powered off by rotating the mechanical operating handle 7. At the same time, the user presses the button 17 to push the propulsion mechanism 4, so that the position relay 6 changes to a separated state, and then the closing and opening relay 14 is opened, so that the primary input plug-in 11, the primary output plug-in 12 and the secondary plug-in 13 are separated from the equipment. At this time, the user can pull the handle 5 to pull out the frame 1.

[0054] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
