Description

Technical Field

[0002] A current transformer is an instrument that converts high voltage and large current into low voltage and small current. It is mainly used to ensure the safe and economical operation of the power system and to monitor and measure the operation of power equipment. It is based on the principle of electromagnetic induction and realizes current measurement through the transformation of primary winding and secondary winding. The switch cabinet can provide protection, metering and monitoring functions for the current sensor, which is convenient for staff to monitor and maintain.

[0003] Due to the narrow internal space of the switch cabinet and the heavy weight of the current transformer, the staff needs to cooperate with the disassembly and assembly tools to complete the installation or disassembly of the current transformer. The existing Chinese public patent document: CN205265111U discloses a lifting device, which is configured to limit the rotation of the rotating frame by abutting the first fixed part of the rotating frame against the cabinet body of the switch cabinet, rotating the rocker, and moving the supporting bracket to the bottom of the current transformer to be disassembled so that it supports the current transformer, and disassembling the fasteners connecting the current transformer and the switch cabinet. At this time, the current transformer is completely placed on the supporting bracket, and the supporting bracket is moved downward to remove the current transformer from the switch cabinet. Although it can provide support for the bottom of the current transformer, after the supporting bracket receives the disassembled current transformer, due to the relatively narrow internal space of the switch cabinet, the supporting bracket is difficult to move downward, and the entire lifting device needs to be pulled outward to remove the current transformer, and the disassembly efficiency is low.

When the pull block 14 moves to the hole position in the middle of the current transformer, the rebound force of the coil spring 16 can be used to rotate and reset the pull block 14 and contact the baffle 15, so that the bearing plate 6 can contact the bottom of the current transformer. At the same time, the bearing plate 6 drives the screw 10 The gear 11 on the rack plate 12 moves along the outside of the rack plate 12, so that the gear 11 drives the screw 10 to rotate, and the screw 10 drives the clamping plate 8 to move downward through the moving block 9. The bottom of the clamping plate 8 contacts the top of the current transformer, thereby clamping and positioning the current transformer, which is convenient for the staff to remove the bolts of the current loop transformer. After the disassembly is completed, the pull rod 4 is pulled to drive the bearing plate 6 to move back, and the bearing plate 6 drives the pull block 14 to press against the inner side of the current transformer, so that the current transformer can be pulled out of the switch cabinet, which is suitable for narrow switch cabinets, thereby achieving the effect of quick disassembly.

[0033] The cleaning mechanism includes a pressing plate 17 fixedly mounted on the side of the moving block 9 away from the clamping plate 8, a positioning plate 18 fixedly mounted on the side of the support plate 7 away from the bearing plate 6, a telescopic air bag 19 fixedly mounted between the positioning plate 18 and the pressing plate 17, an exhaust nozzle 20 fixedly mounted on the side of the support plate 7 close to the bearing plate 6, the exhaust nozzle 20 is located below the sliding cavity of the support plate 7, and the exhaust nozzle 20 is connected to the telescopic air bag 19 through two air pipes, so that when the telescopic air bag 19 is compressed, the exhaust nozzle 20 can spray dust to the outer side of the current transformer through the air pipe, and the clamping plate Two symmetrically distributed pressure strips 21 are arranged at the bottom of the clamping plate 8, and a cavity is opened at the bottom of the clamping plate 8 for the pressure strip 21 to limit the sliding movement.

[0035] Working principle: First, the staff adjusts the height of the telescopic bracket 1 so that the top of the bearing plate 6 is on the same horizontal line as the bottom of the current transformer to be disassembled. Then, the staff pushes the two pull rods 4 to move in the direction of the switch cabinet. The pull rod 4 drives the bearing plate 6 to be inserted into the switch cabinet through the mounting plate 5. The bearing plate 6 drives the pull block 14 to contact the outer side of the current transformer, so that the pull block 14 is rotated and retracted into the inner side of the bearing plate 6. At the same time, the pull block 14 contracts the two coil springs 16 inside the two bearing plates 6 through the rotating rod 13. When the pull block 14 moves to the hole position in the middle of the current transformer, the rebound force of the coil spring 16 is used to drive the rotating rod 13 to rotate, so that the rotating rod 13 drives the pull block 14 to contact the baffle 15. At the same time, the bearing plate 6 drives the gear 11 on the screw 10 to move along the outer side of the rack plate 12, so that the gear 11 drives the screw 10 to rotate.

After the disassembly is completed, the current transformer falls on the top of the supporting plate 6, and the staff pulls the pull rod 4 to move the supporting plate 6 toward the outside of the switch cabinet. The supporting plate 6 drives the pull block 14 to move synchronously, so that the pull block 14 is against the inner side of the current transformer, and the current transformer is pulled out of the switch cabinet. It is suitable for narrow switch cabinets, thereby achieving the effect of fast and smooth disassembly, and improving the safety of disassembly of the current transformer.

Then, the staff releases the pull plate 29, and uses the rebound force of the spring 2 36 to pull the slide plate 27 to reset, and inserts the rod 28 into the slot at the corresponding position to lock the mounting disk 3, which is convenient for the staff to disassemble the tilted current transformer. After the disassembly is completed, the staff pulls the pull plate 29 again, and can use the rebound force of the arc spring 26 to return the mounting disk 3 to its original position, thereby achieving the effect of improving the convenience of disassembly of the current transformer.
