[0021] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0022] Please refer to Figures 1 to 4 A method for quickly replacing a high-voltage capacitor comprises the following steps:

[0023] S1. Obtain and determine the deployment information 1 of the climbing personnel, capacitor loading personnel and the lifting and moving trolley for each area to be repaired that contains a preset number of capacitor racks 3;

[0024] S2, determine whether the location information of the point to be replaced sent by the climbing personnel in the area to be repaired is received, if so, execute step S3, otherwise, determine again;

[0025] S3. Determine whether the trolley standby information sent by the capacitor loader in the area to be repaired after placing the high-voltage capacitor 4 on the liftable movable trolley 1 is received. If so, control the liftable movable trolley 1 to transport the high-voltage capacitor 4 to the point to be replaced. Otherwise, make another judgment.

[0026] From the above description, it can be seen that the beneficial effects of the present invention are: planning the area to be repaired within the occupied area of ​​the high-voltage capacitor group 4, and when carrying out the repair and replacement operations, assigning climbing personnel, capacitor loading personnel and a liftable mobile trolley 1 to each area to be repaired, relying on the cooperation between the climbing personnel, the main controller and the capacitor loading personnel, the high-voltage capacitor 4 is transported to a fixed point by the liftable mobile trolley 1 to assist in completing the replacement operation of the high-voltage capacitor 4, and the automated handling process can effectively reduce the difficulty of repair and replacement of the high-voltage capacitor group 4. When facing the replacement operation of high-voltage capacitors 4 at multiple points, the replacement efficiency of the high-voltage capacitor 4 is improved, saving labor costs.

[0027] Furthermore, the allocation information 1 for determining the climbing personnel, capacitor loading personnel and liftable mobile vehicle is specifically:

[0028] The numbering information of the capacitor racks 3 included in the area to be repaired and the numbering information of the liftable movable trolley 1 are sent to the climbing personnel and the capacitor loading personnel.

[0029] As can be seen from the above description, by sending the serial number information of the capacitor rack 3 and the liftable mobile trolley 1 online to the climbing personnel and capacitor loading personnel, automatic task allocation is achieved and the convenience of inspection and maintenance is improved.

[0030] Furthermore, the controlling of the liftable movable trolley 1 to transport the high-voltage capacitor 4 to the location to be replaced specifically includes:

[0031] According to the position information of the point to be replaced, the number information of the capacitor rack 3 to which the point to be replaced belongs and the layer number and horizontal position of the point to be replaced in the capacitor rack 3 are obtained;

[0032] According to the number information of the capacitor rack 3 and the correspondence between the horizontal position and the plane moving point of the liftable movable trolley 1, the plane moving point corresponding to the point to be replaced is obtained;

[0033] The liftable movable trolley 1 is controlled to move to the plane moving point corresponding to the point to be replaced, and the high-voltage capacitor 4 is lifted to a height corresponding to the number of layers.

[0034] As can be seen from the above description, the position of each high-voltage capacitor 4 on the capacitor rack 3 is accurately located through the numbering information, number of layers and horizontal orientation of the capacitor rack 3, and a corresponding relationship is established between the numbering information and horizontal orientation of the capacitor rack 3 and the plane moving point of the liftable movable trolley 1. After the climbers find the high-voltage capacitor 4 that needs to be replaced, the position of the feedback device is accurately fed back, so that the movable lifting trolley can accurately deliver the new high-voltage capacitor 4 to the corresponding plane moving point.

[0035] Furthermore, the control of the liftable movable trolley 1 to move to the plane moving point corresponding to the point to be replaced is specifically:

[0036] The liftable trolley 1 is controlled to slide on the transport guide rails 2 passing through all the capacitor racks 3 in the area to be repaired until it reaches the plane movement point.

[0037] From the above description, it can be seen that by laying the transport rails 2, the moving path of the liftable mobile cart 1 can be effectively restricted, and at the same time, it is convenient to customize the plane moving points on the transport rails 2 to achieve precise delivery.

[0038] Furthermore, the step of raising the high-voltage capacitor 4 to a height corresponding to the number of layers is as follows:

[0039] The lifting and moving trolley 1 is controlled to move the loading platform 11 carrying the high-voltage capacitor 4 upward on the lifting guide rail 12 until it reaches the height corresponding to the number of layers.

[0040] From the above description, it can be seen that the lifting guide rail 12 is used to lift the loading platform 11 carrying the high-voltage capacitor 4, and the lifting process is stable and the climbing height is easy to control.

[0041] Furthermore, if yes, executing step S3 also includes:

[0042] The capacitor distribution device is controlled to transport the high-voltage capacitor 4 to the area to be repaired corresponding to the point to be replaced.

[0043] From the above description, it can be seen that the capacitor distribution device is controlled to allocate high-voltage capacitors 4 to each area to be repaired, and cooperates with the operation process of the liftable movable vehicle 1 to improve the degree of automation of the replacement of the high-voltage capacitors 4 and improve the operation efficiency.

[0044] Furthermore, it also includes:

[0045] S4. Receive and determine whether the replacement completion information sent by the climber contains the new location information of the point to be replaced. If so, control the liftable movable vehicle 1 to move to the point to be replaced.

[0046] From the above description, it can be seen that after delivering the high-voltage capacitor 4 at a point to be replaced, it can be quickly moved to a new point to be replaced, and the replaced high-voltage capacitor 4 can be transported away, and then a new high-voltage capacitor 4 can be delivered, thereby realizing the connection operation between multiple point replacements and improving work efficiency.

[0050] From the above description, it can be seen that the beneficial effects of the present invention are: planning the area to be repaired within the occupied area of ​​the high-voltage capacitor group 4, and when carrying out the repair and replacement operations, assigning climbing personnel, capacitor loading personnel and a liftable mobile trolley 1 to each area to be repaired, relying on the cooperation between the climbing personnel, the main controller and the capacitor loading personnel, the high-voltage capacitor 4 is transported to a fixed point by the liftable mobile trolley 1 to assist in completing the replacement operation of the high-voltage capacitor 4, and the automated handling process can effectively reduce the difficulty of repair and replacement of the high-voltage capacitor group 4. When facing the replacement operation of high-voltage capacitors 4 at multiple points, the replacement efficiency of the high-voltage capacitor 4 is improved, saving labor costs.

[0051] Further, it also includes a capacitor distribution device;

[0052] The capacitor distribution device is provided with distribution openings corresponding one to one with the transport guide rails 2 .

[0054] Furthermore, the liftable mobile trolley 1 includes a movable base 13, a lifting guide rail 12 and a loading platform 11;

[0055] The movable base 13 is slidably disposed on the transport guide rail 2 , the lifting guide rail 12 is disposed on the movable base 13 , and the loading platform 11 is liftably disposed on the lifting guide rail 12 .
