The actuating element, motor drive, energy storage mechanism, and auxiliary switch are all integrated into the actuation housing.

[0070] It should be noted that the connection components include a control plug, an actuation plug, and a secondary cable. The control plug is located on the outside of the control mechanism, and the actuation plug is located on the outside of the actuation mechanism 8. The control plug is connected to the actuation plug via the secondary cable.

[0071] In this embodiment of the invention, the connection assembly includes a control plug, an actuation plug, and a secondary cable. The control plug is fixedly installed on the outside of the control mechanism, and the actuation plug is fixedly installed on the outside of the actuation mechanism 8. The control plug is connected to the actuation plug via the secondary cable. Both the control plug and the actuation plug are aviation plugs.

[0072] It is worth mentioning that the secondary cable is encased in a cable corrugated tube to prevent water ingress, moisture, and external damage.

[0073] See Figure 1 As shown, the condition monitoring system includes a controller 2, a condition monitoring component, an input interface, and a control interface. The controller 2 is connected to the condition monitoring component via the input interface. The condition monitoring component is used to monitor the condition data of the disconnecting switch in real time and sends the monitoring data to the controller 2. The condition monitoring data includes gas insulation parameters, mechanical characteristic parameters, and current parameters. The controller 2 is connected to the motor associated with the disconnecting switch via the control interface.

[0074] In this embodiment of the invention, the condition monitoring system includes a controller 2, a condition monitoring component, an input interface, and a control interface. The condition monitoring component includes a gas sensor, a temperature sensor, and a heater AC current sensor. The controller 2 is connected to the gas sensor, temperature sensor, and heater AC current sensor via the input interface. The condition monitoring component is used to monitor the condition data of the disconnect switch in real time and sends the condition monitoring data to the controller 2.

Each input interface can connect to 1–8 sensors, and each disconnect switch can connect to a maximum of 10 input interfaces. The controller 2 is connected to the motor associated with the disconnect switch via the control interface.

[0075] It should be noted that controller 2 includes a data receiving module, a first analysis module, and a second analysis module. The data receiving module is used to receive real-time switch operating torque data, switch operating angle data, gas insulation parameters, mechanical characteristic parameters, and current parameters. The first analysis module is used to control the activation and deactivation of the audible and visual alarm 3 based on preset standard switch threshold data, gas insulation parameters, mechanical characteristic parameters, and current parameters. The standard switch threshold data includes standard gas threshold ranges, standard mechanical characteristic threshold ranges, and standard current threshold ranges.

[0076] The second analysis module is used to control the start and stop of the audible and visual alarm 3 based on preset standard action threshold data, switch action torque data, and switch action angle data.

[0077] In this embodiment of the invention, the controller 2 includes a data receiving module, a first analysis module, and a second analysis module. The data receiving module receives in real-time switch operating torque data, switch operating angle data, gas insulation parameters, mechanical characteristic parameters, and current parameters. The first analysis module controls the activation and deactivation of the audible and visual alarm 3 based on preset standard switch threshold data, gas insulation parameters, mechanical characteristic parameters, and current parameters. The standard switch threshold data includes standard gas threshold ranges, standard mechanical characteristic threshold ranges, and standard current threshold ranges. The second analysis module controls the activation and deactivation of the audible and visual alarm 3 based on preset standard operating threshold data, switch operating torque data, and switch operating angle data. The first analysis module, the data receiving module, and the second analysis module are communicatively connected.

[0078] It should be noted that the first analysis module includes a first analysis submodule, a second analysis submodule, and a third analysis submodule. The first analysis submodule is used to determine whether the gas insulation parameter is within the standard gas threshold range. When the gas insulation parameter is not within the standard gas threshold range, it controls the audible and visual alarm 3 to activate. The second analysis submodule, when the gas insulation parameter is within the standard gas threshold range, determines whether the mechanical characteristic parameter is within the standard mechanical characteristic threshold range. When the mechanical characteristic parameter is not within the standard mechanical characteristic threshold range, it controls the audible and visual alarm 3 to activate. The third analysis submodule, when the mechanical characteristic parameter is within the standard mechanical characteristic threshold range, determines whether the current parameter is within the standard current threshold range. When the current parameter is not within the standard current threshold range, it controls the audible and visual alarm 3 to activate.

[0079] In this embodiment of the invention, the controller 2 includes a data receiving module, a first analysis module, and a second analysis module. The first analysis submodule is used to determine whether the gas insulation parameter is within the standard gas threshold range. When the gas insulation parameter is not within the standard gas threshold range, it controls the audible and visual alarm 3 to activate and broadcast a voice prompt indicating that the gas insulation parameter is unqualified. The second analysis submodule is used to determine whether the mechanical characteristic parameter is within the standard mechanical characteristic threshold range when the gas insulation parameter is within the standard gas threshold range. When the mechanical characteristic parameter is not within the standard mechanical characteristic threshold range, it controls the audible and visual alarm 3 to activate and broadcast a voice prompt indicating that the isolating switch is faulty. The third analysis submodule is used to determine whether the current parameter is within the standard current threshold range when the mechanical characteristic parameter is within the standard mechanical characteristic threshold range. When the current parameter is not within the standard current threshold range, it controls the audible and visual alarm 3 to activate and broadcast a voice prompt indicating that the isolating switch is overcurrent or undercurrent based on the magnitude of the current parameter.

[0080] It should be noted that the second analysis module includes a fourth analysis submodule, a fifth analysis submodule, and a sixth analysis submodule. The fourth analysis submodule is used to determine whether the rotation angle of the switch action angle data is consistent with the standard rotation angle in the preset standard action threshold data. When the rotation angle is inconsistent with the standard rotation angle, the audible and visual alarm 3 is activated.

[0081] The fifth analysis submodule is used to determine whether the curve characteristic parameters of the switch action angle data are consistent with the standard curve characteristic parameters when the rotation angle is consistent with the standard vibration angle.

[0082] When the curve characteristic parameters are inconsistent with the standard curve characteristic parameters, the closed region constructed by the corner curve of the curve characteristic parameters and the standard corner curve of the standard curve characteristic parameters is determined as the target region. The target region is differentiated to obtain the corresponding corner correlation coefficient. The sixth analysis submodule is used to determine whether the corner correlation coefficient is within a preset correlation coefficient threshold range. When the corner correlation coefficient is not within the correlation coefficient threshold range, the audible and visual alarm 3 is activated. When the corner correlation coefficient is within the correlation coefficient threshold range, the audible and visual alarm 3 is activated based on a comparison between the switch action torque data and the standard torque threshold in the standard action threshold data.

[0083] In this embodiment of the invention, the second analysis module includes a fourth analysis submodule, a fifth analysis submodule, and a sixth analysis submodule. The fourth analysis submodule is used to determine whether the rotation angle of the switch action angle data is consistent with the standard rotation angle in the preset standard action threshold data. When the rotation angle is inconsistent with the standard rotation angle, the audible and visual alarm 3 is activated, and a voice prompt is given indicating that the isolating switch action is not in place. The fifth analysis submodule is used to determine whether the curve characteristic parameters of the switch action angle data are consistent with the standard curve characteristic parameters when the rotation angle is consistent with the standard vibration angle. When the curve characteristic parameters are consistent with the standard curve characteristic parameters, the isolating switch is normal. When the curve characteristic parameters are inconsistent with the standard curve characteristic parameters, the operating torque and rotation angle curve of the isolating switch are analyzed, and the closed region constructed by the rotation angle curve of the curve characteristic parameters and the standard rotation angle curve of the standard curve characteristic parameters is determined as the target region. The target region is differentiated to obtain the corresponding rotation angle correlation coefficient. (The fifth analysis submodule is also used to divide the target area into a contact-finger contact area and a contact-finger pre-contact area according to the disconnecting switch's operation period. The contact-finger contact area and the contact-finger pre-contact area are then differentiated to obtain the contact-finger contact correlation coefficient and the contact-finger pre-contact correlation coefficient, respectively.) The sixth analysis submodule is used to determine whether the corner correlation coefficient is within a preset correlation coefficient threshold range. (The sixth analysis submodule is also used to determine whether the contact-finger contact correlation coefficient is within a preset first correlation coefficient threshold range, and whether the contact-finger pre-contact correlation coefficient is within a preset second correlation coefficient threshold range.) When any of the corner correlation coefficient, the contact-finger contact correlation coefficient, or the contact-finger pre-contact correlation coefficient is not within a threshold range (the threshold range includes the correlation coefficient threshold range, the first correlation coefficient threshold range, and the second correlation coefficient threshold range), the audible and visual alarm 3 is activated, and a voice prompt indicates that the disconnecting switch operation is incomplete. When the corner correlation coefficient is within a correlation coefficient threshold range, the comparison result between the switch operation torque data and the standard torque threshold in the standard operation threshold data determines whether to activate the audible and visual alarm 3.

[0084] It is worth mentioning that the determination of whether to activate the audible and visual alarm 3 is based on the comparison between the switch action torque data and the standard torque threshold in the standard action threshold data. Specifically, the switch action torque data includes the extreme torque change, the average torque change, the torque change amplitude before switch action, and the torque change amplitude after switch action. If any of the following conditions are met: the extreme torque change exceeds a preset over-limit threshold, the average torque change exceeds a preset first change amplitude threshold, the torque change amplitude before switch action exceeds a preset second change amplitude threshold, or the torque change amplitude after switch action exceeds a preset third change amplitude threshold, then the audible and visual alarm 3 is activated, and a voice prompt is given indicating that the isolating switch action is incomplete.

[0085] See Figure 1 As shown, the controller 2 is equipped with an anti-accidental touch component 4. The anti-accidental touch component 4 is snap-fitted to the controller 2.

[0086] In this embodiment of the invention, the controller 2 is equipped with an anti-accidental touch component 4. It is fixed to the controller 2 by a snap-fit ​​and automatically locks when rotated to a fixed position.

[0087] It should be noted that the status monitoring system is connected to the audible and visual alarm 3.

[0088] In this embodiment of the invention, the status monitoring system is communicatively connected to the audible and visual alarm 3.

[0089] It is worth mentioning that controller 2 is snapped onto the guide rail inside the mechanism box 1. Controller 2 can indicate seven states of the disconnect switch through color changes: power supply, fault, open, closed, remote, local, manual, and emergency stop. Controller 2 also has remote and local knobs to switch between remote and local control modes of the disconnect switch. Controller 2 also has open, closed, local, and remote buttons, each operating independently. These buttons are connected to the chip's input interface. Pressing the open or closed button allows for intelligent control of the disconnect switch's opening and closing. The controller 2 panel has indicator lights, knobs, and a digital display. The digital display is used to display controller 2 fault codes, with five fault display functions: ERR1: Three-phase phase sequence error; ERR2: Overcurrent in the motor during opening / closing operation; ERR3: Timeout during opening / closing operation; ERR4: No interlocking signal detected during opening / closing operation; ERR5: Simultaneous detection of open and closed positions during opening / closing operation.

[0090] In this embodiment of the invention, the modular device of the disconnector mechanism box includes a control mechanism, an actuation mechanism, an audible and visual alarm, a mechanism box, a status monitoring system, and an action monitoring component. The mechanism box is fixedly installed at the bottom of the disconnector frame and connected to the disconnector via a drive shaft. The control mechanism and the actuation mechanism are installed inside the mechanism box, and the control mechanism is connected to the actuation mechanism via a connecting component. The action monitoring component is mounted on the main shaft operating rod of the disconnector and is used to collect the action data of the disconnector in real time and send it to the status monitoring system. The audible and visual alarm is fixedly installed on the top of the mechanism box, and the status monitoring system is mounted on the actuation mechanism. The status monitoring system is used to respond to monitoring commands, collect the operating condition data of the disconnector in real time, and control the start and stop of the audible and visual alarm based on the operating condition data and the action data. This solves the technical problem that existing disconnector mechanism boxes are unable to determine whether the operating force of the disconnector is within the normal torque range, thus triggering an alarm signal prematurely and reducing the reliability of the disconnector mechanism box operation. This application sets up a motion monitoring component on the main shaft of the disconnector switch, which enables an early warning for the disconnector switch when the operating force exceeds the normal torque range. At the same time, when defects or malfunctions occur in the control mechanism or action mechanism, the disconnector switch mechanism box can be repaired simply by plugging and unplugging the connecting component and replacing it with a new spare control mechanism or action mechanism, thereby improving the reliability of the disconnector switch mechanism box operation.
