[0002] A current transformer is an instrument that converts a large primary current into a small secondary current based on the principle of electromagnetic induction. Before a current transformer is put into use, its waterproof performance is usually tested to reduce the probability of a safety accident caused by water seeping into the current transformer when it is put into use.

[0003] For example, the patent with application number CN202011033489.4 discloses a current transformer detection device.

[0015] 2. The present invention manually presses down the push rod to drive the sleeve plate and the wiping roller to descend along the two guide rods. During the descent, the circumferential outer wall of the wiping roller rubs against the inner side of the glass window to rotate, so that the water droplets on the inner side of the glass window are cleaned by the rotation of the wiping roller, and the glass window is wiped clean to make the glass window clear, thereby avoiding the situation where too many water droplets are sprayed on the inner side of the glass window, resulting in the staff being unable to observe the detection status of the current transformer through the glass window.

[0016] 3. The present invention drives the carrier rod and the transmission rack to descend through the pressure plate. When they descend to a certain position, the transmission rack meshes with the transmission gear, causing the transmission gear to start rotating, thereby driving the slide plate, two sets of clamping plates and two test wires to rise, so that the two sets of clamping plates quickly pull the two test wires upward, directly disconnecting the two test wires from the current transformer, thereby avoiding the current transformer from continuing to be energized after water enters it, causing a safety accident.

[0032] like Figure 5 As shown: a transmission rack 5 is slidably installed on the rear side of the top of the top plate 4; the transmission rack 5 includes: a carrier rod 501, which is arranged at the middle of the top of the transmission rack 5, and the carrier rod 501 is a cylindrical rod-shaped structure; a pressure plate 502, which is arranged at the top of the carrier rod 501, and the pressure plate 502 is a rectangular structure, and two springs are arranged between the bottom of the pressure plate 502 and the top of the top plate 4. By pressing the pressure plate 502 downward, the carrier rod 501 and the transmission rack 5 are driven to descend.

Compared with manually pressing the push rod 702 to complete the cleaning work, it saves time and effort. At the same time, completing the cleaning work by the cylinder also makes the device more automated.

[0036] Working principle: When in use, first place the current transformer between the two clamping plates 201, then rotate the threaded rod 301 to make the two guide blocks 302 use the opposite direction of their threads to drive the two sliding columns 2 and the two clamping plates 201 to move relative to each other, so that the two clamping plates 201 clamp the current transformer, and then connect the two test wires to the current transformer by passing them through the two through holes and the two top grooves 406 in turn. At the same time, the four clamping plates 407 will clamp and fix the two test wires respectively under the action of the spring push, thus completing the loading and connection work, and then drive the two water storage cylinders 601, the two shaft tubes 6 and the two spraying discs 602 to rotate through the motor and the pulley, so that the two spraying discs 602 will spray water evenly on the current transformer through the two groups of spraying grooves and the two groups of spraying holes under the action of centrifugal force during rotation, thereby creating a humid external environment and testing the waterproof performance of the current transformer. Then, the push rod 702 is pressed down manually to drive the sleeve plate 701 and the wiping roller 704 to descend along the two guide rods 7. During the descent, the circumferential outer wall of the wiping roller 704 rotates due to friction with the inner side of the glass window, so that the wiping roller 704 cleans the water droplets on the inner side of the glass window, thereby ensuring the clarity of the glass window, making it convenient for the staff to clearly observe the condition of the current transformer being tested through the glass window. When the staff observes that water has seeped into the current transformer, the pressing plate 502 is pressed down manually to drive the carrier rod 501 and the transmission rack 5 to descend. When it descends to a certain position, the transmission rack 5 engages with the transmission gear 404 to rotate the transmission gear 404, thereby driving the slide plate 403, the two sets of clamping plates 407 and the two test wires to rise, and then the two test wires are pulled upward, so that the test wires are no longer in contact with the current transformer, effectively reducing the probability of safety hazards.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
