I. Overview
The CJM2 electric operating mechanism can be used for 72.5-145kV gas insulated metal enclosed switchgear (GIS) to operate the device of the three position isolation/grounding switch in GIS switchgear. (That is, one three position mechanism can achieve the opening and closing functions of the isolation switch in GIS, as well as the opening and closing functions of the grounding switch in GIS.)

2�� Principle
This mechanism uses an electric motor to rotate, which drives the lead screw to rotate through a cylindrical gear pair. The dial wheel is turned counterclockwise by the dial pin on the screw rod nut in the lead screw pair (when the dial wheel rotates, it disengages from the dial pin on the lead screw nut). The dial wheel directly drives the main shaft and the gears on the main shaft to rotate, and the gears are in contact with the output gears of the three station mechanism, thereby achieving accurate opening and closing of the isolation and grounding switch. The institution has both manual and electric operation functions.

4. Working principle and structure
The CX-6 mechanism is driven by an electric motor and transmits torque to the output shaft through gears, worm gears, and worm gears. During installation, it is connected to an isolation switch through a steel pipe for opening and closing. It mainly consists of an electric motor, a mechanical reduction transmission system, an electrical control system, and a casing.
The electric motor is a three-phase AC asynchronous motor: the electrical control system includes automatic switches, remote/stop/local switching switches, manual electric interlocking devices, opening and closing buttons, contactors, travel switches, etc.
The box is made of steel plate or stainless steel plate to provide support and protection. For ease of installation and maintenance, one door is opened on the front and one door is opened on the side.
The operating procedure for the CX-6 mechanism is as follows.
4.2.1 Electric operation
Set the interlocking device on the panel to the electric locking position, set the local remote control switch to the appropriate position, and close the power switch to connect the power supply. When it is necessary to open the circuit, press the opening button to connect the control coil of the opening contactor, so that the motor circuit is connected. When the electric drive approaches the opening point position, the limit switch will act to cut off the power supply to the control coil of the opening contactor, reset the opening contactor, and cut off the power supply to the motor. The mechanical limit device will limit the mechanism to the accurate opening position.
When closing, press the closing button, and the electric motor drives the deceleration device to drive the isolation switch and grounding switch connected to the spindle to achieve closing. The operating principle is the same as opening.
During the opening and closing process, if there is a need to stop halfway or if there is an abnormal situation, the control power can be cut off by pressing the stop button. The lower part of the main shaft of the mechanism is equipped with 8 pairs of auxiliary switches (4 normally open, 4 normally closed) for interlocking and signal indication
This institution is suitable for remote control system devices, realizing remote control, and can also be operated locally in front of the electric motor mechanism. For this purpose, there are remote/stop/local switches When the mechanism is adjusted or repaired, it can be moved to the local position and operated in front of the mechanism (at this time, the remote power has been cut off). When the mechanism is moved to the remote position, the opening and closing buttons do not work and can only be remotely controlled
The mechanism equipped with a heater, when it is necessary to increase the temperature inside the box to dispel humid air and prevent electrical components from getting damp, can close the heater switch and put the heater into operation Turn on the heater switch after completing the work

[Electric operating mechanism]CJ11A-G series maintenance free electric motor operating mechanism

2026-6-16 14:06:21

Overview of CJ11A-G series maintenance free electric motor operating mechanism
At present, there are inevitable defects in the mechanisms used for high-voltage isolating switches in China, such as an open transmission structure that requires regular lubrication or maintenance, poor environmental adaptability, low protection level, loud noise during operation, and short service life. To solve these problems, our factory organized scientific research efforts to develop the CJ11A-G series maintenance free electric motor operating mechanism. The mechanical deceleration part of this mechanism adopts a fully enclosed structure for maintenance free operation to replace the traditional open structure. Its maintenance free, high reliability, and strong interchangeability make it the preferred product to replace traditional mechanisms.

2. Environmental conditions for use
2.1 Same as the high-voltage isolation switch and grounding switch provided.
The voltage variation range of the power supply is 85% to 110% of the rated voltage.
3. Structure and Performance Characteristics
3.1 CJ11A-G series maintenance free electric motor operating mechanism (hereinafter referred to as CJ11A-G mechanism), driven by an AC motor, is used to operate high-voltage isolation switches and grounding switches through a fully enclosed gear and worm gear reduction part. It can be remotely controlled, electrically controlled locally, or manually operated using a handle. Manual and electric interlocking devices are installed inside the box to achieve electrical interlocking between manual and electric operations.
The core components of the CJ11A-G mechanism (gears and worm gear reduction parts) are sealed in a high-quality aluminum alloy box as a whole, which is not affected by the external environment. The transmission of the mechanism is smooth, noiseless, does not require any lubricating grease, and completely achieves maintenance free operation. Due to the use of high-quality aluminum alloy materials for both the casing and motor housing, the mechanism is lightweight, has good heat dissipation performance, and excellent corrosion resistance.
3.3 In order to meet the requirements of various installation scenarios and installation methods, as well as the need for users to replace old mechanisms, the CJ11A-G mechanism considers different installation methods, rotation angles, and center height requirements, and can almost be matched with various series of high-voltage isolation switches. After attaching various mounting plate accessories to the operating mechanism, the installation size is exactly the same as that of the old model mechanism (such as CJ2, CJ5, CJ6, etc.), and no adjustment is required when replacing the old mechanism.
