Description

Technical Field

[0001] The present invention relates to the technical field of insulation testing of electric energy meters, in particular to an insulation testing device for a single-phase intelligent electric energy meter. Background Art

[0002] Smart electricity meters are composed of measurement units, data processing units, communication units, etc., and have functions such as electricity metering, data processing, real-time monitoring, automatic control, and information interaction. Smart electricity meters can be divided into single-phase meters and three-phase meters according to user types, and can be divided into local meters and remote meters according to different payment methods. Single-phase meters, as the name suggests, are electricity meters used by ordinary users to measure 220V electricity. Three-phase meters are electricity meters used to measure 380V electricity used in industry. Local meters are electricity meters that can be paid by IC cards at the user's side. Remote meters are generally not installed within the user's range, and users need to go to the power supply bureau to pay.

[0003] Smart energy meters need to undergo insulation performance tests before use to ensure their stability during operation.

[0004] Upon investigation, a Chinese invention patent discloses an insulation test device for a single-phase smart electricity meter (publication number: CN116773871B). The device comprises a base plate and an electricity meter. A test device is mounted on one end of the base plate, equipped with a probe for performing insulation tests on the meter. A first slot is defined at the top of the base plate, and a second slot is defined in the center of the base plate, connected to the center of the first slot. An adjustment mechanism slides symmetrically within the first slot, equipped with a clamping mechanism for moving and securing the meter. A drive mechanism slides within the second slot, and the drive and adjustment mechanisms are connected by a pull-cord transmission. To perform an insulation test on the meter, the meter is placed on the base plate and slid relative to the test device. The crossbar and meter cooperate to enable the adjustment mechanism to move the clamping mechanism relative to the meter, clamping the meter and automatically centering the meter to align with the probe.

[0005] Although the above patent places the electric energy meter on the bottom plate and slides it relative to the direction of the test device through the arrangement of the bottom plate and the cross plate, the adjustment mechanism drives the clamping mechanism to move relative to the electric energy meter through the cooperation of the cross plate and the electric energy meter, and completes the clamping of the electric energy meter. It can also automatically center the electric energy meter and align it with the position of the probe, avoiding deformation of the probe due to accidental excessive force by personnel, which will affect the next test;

[0006] However, during the insulation test of the single-phase smart electricity meter, a protective cover needs to be installed at the connection between the probe and the single-phase smart electricity meter to avoid accidental touch during the test and causing danger. However, after long-term use, dust will adhere to the inside of the protective cover. When the probe is connected to the single-phase smart electricity meter, the dust follows the probe into the inside of the single-phase smart electricity meter, thereby affecting the insulation test of the single-phase smart electricity meter, causing deviations in the results of the insulation test of the single-phase smart electricity meter, and affecting the subsequent judgment of the insulation performance of the single-phase smart electricity meter.

[0007] Therefore, the present invention provides an insulation testing device for a single-phase smart electric energy meter to solve the above problems. Summary of the Invention

[0023] (3) Beneficial effects

[0024] Based on the setting of the cleaning mechanism and the single-phase electric energy meter and other structures, the single-phase electric energy meter is clamped by the mutual cooperation of the tightening spring and the installation box, and a driving motor and a threaded rod are used to make the installation box drive the airbag and the single-phase electric energy meter to be inserted into the interior of the hollow box, so that the airbag fits with the isolation plate, so that the isolation plate squeezes the airbag and causes the airbag to deform, and the gas in the airbag is sprayed into the interior of the hollow box through the nozzle to clean the interior of the hollow box and the surface of the probe, so that the cleaned dust is discharged into the collection tank through the one-way valve, so that during the insulation test of the single-phase electric energy meter, the dust of the probe and the hollow box are cleaned at the same time, so as to prevent dust from following the probe into the single-phase electric energy meter and affecting the result of its insulation test, thereby improving the accuracy of the insulation test result of the single-phase electric energy meter;

[0025] Through the cooperation between the vibration motor and the carrying plate, after the insulation test of the single-phase electricity meter is completed, the single-phase electricity meter is separated from the probe, and the vibration motor is started, so that its output end drives the carrying plate and the probe to vibrate, so that the oxidized debris on the surface of the probe falls into the inside of the hollow box. When the insulation test of other single-phase electricity meters is performed, the single-phase electricity meter is slid inside the hollow box, thereby pushing the oxidized debris to move to the through groove, so that the oxidized debris falls into the collection box, thereby not only preventing the oxidized debris from adhering to the probe surface and affecting the subsequent insulation test of the single-phase electricity meter, but also the oxidized debris can be cleaned and collected during the test of the single-phase electricity meter, making the insulation test device of the single-phase smart electricity meter more convenient to use;

[0026] Based on the mutual cooperation of the cleaning mechanism and the testing mechanism, when an abnormality occurs during the insulation test of the single-phase electricity meter, the electric push rod is automatically started to separate from the mounting rod. The mounting rod and the push plate are no longer limited. Through the elastic force of the spring assembly, the mounting rod drives the bearing plate and the probe to slide on the support rod, so that the probe is quickly separated from the single-phase electricity meter, and the high-voltage output is immediately cut off, avoiding personal injury and equipment damage caused by untimely disconnection of the probe from the single-phase electricity meter;

[0027] The movable plate is limited by the mutual cooperation of the pushing plate and the rotating plate, so that when the single-phase electric energy meter is inserted into the hollow box, the movable plate fits tightly against the single-phase electric energy meter to avoid the single-phase electric energy meter being inserted too deeply and causing damage to the probe and the connection of the single-phase electric energy meter. When the pushing rod follows the movement of the mounting rod, the rotating plate pushes the movable plate to move, so that the movable plate applies a pushing force to the single-phase electric energy meter, thereby causing the arc-shaped elastic plate to deform, and the single-phase electric energy meter follows the arc-shaped elastic plate to move backward, thereby accelerating the speed at which the single-phase electric energy meter is separated from the probe.

[0062] The sliding groove 409 is used for sliding guidance of the sliding block 410;

[0063] The threaded rod 411 is used to drive the sliding block 410 and the mounting box 401 to move on the upper surface of the support base 201;

One end of the support rods 301 is fixedly connected to a spring assembly 302. One end of the spring assembly 302 is fixedly connected to a mounting rod 303 that is slidably sleeved on the surface of the support rod 301. One end of the mounting rod 303 is fixedly connected to a connecting block 304. The lower surface of the connecting block 304 is fixedly connected to a supporting plate 305.

[0074] The support rod 301 is used to support the mounting rod 303 and the spring assembly 302;

[0075] Among them, the spring assembly 302 is used to drive the installation rod 303 to move;

[0076] The connecting block 304 is used to drive the carrying plate 305 to move through the mounting rod 303;

[0077] The test mechanism 3 also includes probes 306 in a rectangular array fixedly connected to one side of the carrier plate 305 and corresponding to the single-phase electric energy meter 5. Both sides of the surface of the mounting rod 303 are plugged with electric push rods 307 fixedly connected to the hollow box 405. The surface of the mounting rod 303 is fixedly connected to a push plate 308 corresponding to the electric push rods 307. The surface of the mounting rod 303 is affixed to a rotating plate 309 rotatably connected to the interior of the hollow box 405 via a rotating shaft.

[0078] Wherein, the probe 306 is used to connect to the single-phase electric energy meter 5;

[0079] Among them, the electric push rod 307 is used to limit the installation rod 303;

[0080] The pushing plate 308 is used to push the rotating plate 309 to rotate inside the hollow box 405;

[0081] Specifically, when the single-phase electric energy meter 5 is plugged into the test space, the probe 306 is plugged into the single-phase electric energy meter 5, and the power supply component 203 supplies power to the probe 306 to perform an insulation test on the single-phase electric energy meter 5;

[0082] The testing mechanism 3 also includes a movable plate 310 slidably connected to the hollow box 405 and in contact with the rotating plate 309. The movable plate 310 corresponds to the single-phase electric energy meter 5. The two edges of the other side of the supporting plate 305 are fixedly connected to guide rods slidably connected to the hollow box 405. The outer arc surface of the mounting rod 303 is fixedly connected to a vibration motor 311 whose output end is fixedly connected to the supporting plate 305.

[0083] The movable plate 310 is used to limit and push the single-phase electric energy meter 5;

[0084] Wherein, the guide rod is used to guide the carrying plate 305;

[0085] The vibration motor 311 is used to drive the supporting plate 305 to vibrate;

[0086] Specifically, after the insulation test of the single-phase electric energy meter 5 is completed, the single-phase electric energy meter 5 is reset following the installation box 401 based on the driving motor 413 and the threaded rod 411, so that the single-phase electric energy meter 5 is separated from the probe 306, and the vibration motor 311 is started, so that its output end drives the supporting plate 305 to vibrate, and drives the probe 306 to vibrate synchronously, so as to clean the oxidized debris on the surface of the probe 306, so that the oxidized debris falls into the test space, thereby preventing the oxidized debris from affecting other single-phase electric energy meters 5 during subsequent insulation tests;

[0087] When performing insulation testing on other single-phase electric energy meters 5, the single-phase electric energy meter 5 is slid inside the hollow box 405, thereby pushing the oxidized debris to move to the through slot 202, causing the oxidized debris to fall into the collection box 103, thereby preventing the oxidized debris from adhering to the surface of the probe 306 and affecting the subsequent insulation testing of the single-phase electric energy meter 5. The oxidized debris can also be cleaned and collected during the testing of the single-phase electric energy meter 5, making the insulation testing device of the single-phase smart electric energy meter more convenient to use;

[0088] Specifically, when an abnormality occurs during the insulation test of the single-phase electric energy meter 5, the electric push rod 307 is activated so that it no longer limits the mounting rod 303. As a result, the elastic force of the spring assembly 302 causes the mounting rod 303 to slide on the support rod 301, driving the carrier plate 305 and the probe 306 to slide synchronously, so that the probe 306 is separated from the single-phase electric energy meter 5, and the high-voltage output is immediately cut off, thereby avoiding personal injury and equipment damage caused by the untimely disconnection of the probe 306 from the single-phase electric energy meter 5.

[0089] At the same time, during the movement of the mounting rod 303, the pushing plate 308 is also driven to move, so that the pushing plate 308 drives the rotating plate 309 to rotate in the test space, so that one side of the rotating plate 309 pushes the moving plate 310 to move, so that the moving plate 310 applies a pushing force to the single-phase electric energy meter 5, thereby causing the arc-shaped elastic plate 412 to deform, and the single-phase electric energy meter 5 moves backward following the arc-shaped elastic plate 412, thereby accelerating the speed of the single-phase electric energy meter 5 being separated from the probe 306, and further accelerating the efficiency of cutting off the high-voltage output;

[0090] The interior of the hollow box 405 is provided with a receiving groove 6 based on the isolation plate 406. The receiving groove 6 is connected to the hollow box 405 via a one-way valve 408. The lower surface of the support base 201 is in contact with the support box 102, and the collection box 103 is in contact with the lower surface of the support base 201. The inner bottom wall of the hollow box 405 is provided with a path array with connecting grooves corresponding to the sliding grooves 409.

[0091] The receiving tank 6 is used to collect dust and gas discharged from the one-way valve 408;

[0092] The connecting groove is used to prevent the hollow box 405 from causing movement obstruction to the movement of the installation box 401 .

[0093] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
