[0002] With socioeconomic development and improved living standards, electricity users are using a growing variety of devices, and their load characteristics are becoming increasingly complex.

When the present invention is used, the magnetic shield first shields part of the electromagnetic interference. When the magnetic field of the electromagnetic interference reaches the square rubber ring, the hydroxyl iron powder particles will be magnetized under the action of the magnetic field, offsetting part of the external magnetic field. The square rubber ring uses rubber material as a matrix, which helps to improve the overall anti-electromagnetic interference performance. Move the pull plate downward, drive the connecting plate and the limit rod downward through the pull rod, and then pull one end of the tooth tie bar to tighten the tooth tie bar, and tightly attach the square rubber ring to the connection of the load monitor body shell to increase the tightness, which is conducive to improving the anti-electromagnetic interference effect and reducing the impact on data acquisition accuracy.

[0015] Preferably, a handle is fixedly mounted on the top of the monitor body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the outer magnetic shielding of the box and the outer magnetic shielding of the cover primarily protect against high-frequency electromagnetic interference and are made of materials such as copper or aluminum. Metal materials have excellent reflection and conduction properties for high-frequency electromagnetic interference, reflecting or directing it toward the ground, preventing it from entering the load monitor. The middle magnetic shielding of the box and the cover is used to shield electromagnetic interference in the mid-frequency range and is made of ferrite. Ferrite has excellent electromagnetic shielding properties in the mid-frequency range and can convert electromagnetic interference energy into heat through its own magnetic losses, thereby reducing electromagnetic interference in the mid-frequency range. The inner magnetic shielding of the box and the cover, located near the load monitor, primarily blocks low-frequency electromagnetic interference and is made of high-permeability Permalloy. Permalloy has high magnetic permeability in the low-frequency range and effectively directs low-frequency magnetic fields around the load monitor, reducing the impact of low-frequency interference on internal electronic components. The optimized magnetic shielding more effectively shields electromagnetic interference of different frequencies, significantly reducing interference to the electronic components within the load monitor. In a complex electromagnetic environment, the deviation of the collected data will be significantly reduced, which will improve the accuracy and reliability of the load data and provide more reliable data support for subsequent power distribution optimization, fault location and other tasks. Reducing the impact of electromagnetic interference on the device will help improve the stability and service life of the load monitor itself. When electronic components operate in a stable electromagnetic environment, the probability of failure can be reduced, reducing equipment damage and maintenance costs caused by electromagnetic interference, and ensuring the smooth progress of low-voltage power inspection work. The magnetic isolation plate is made of aluminum film and covers the top of the control panel, which is conducive to good reflection and conduction of electromagnetic interference at the position of the control panel. For higher-frequency electromagnetic interference, the aluminum film can reflect it away, reducing interference entering the interior of the equipment.

[0017] 2. In the present invention, the mounting rails are provided on both sides of the interior of the anti-interference mechanism, and the sliding blocks are provided on both sides of the exterior of the load monitor mechanism. During installation, the sliding blocks are slid into the interior of the mounting rails. During the sliding process, the guide strips and the guide grooves cooperate to achieve a guiding effect, which is conducive to improving the stability during sliding. During the sliding process, the handles are pinched by fingers to make the sliding blocks slide toward each other inside the mounting tube. At the same time, the telescopic rod and the spring member are compressed to achieve the withdrawal of the fixing pin. When the sliding block is completely slid into the interior of the mounting rails, the fingers are released, and the elastic action of the spring member drives the telescopic rod to extend, thereby pushing the sliding block to extend toward both ends inside the mounting tube. The fixing pins are inserted into the fixing holes on the mounting rails and the sliding blocks, thereby achieving a rapid limiting effect, which is conducive to ensuring stability after installation. The side support blocks are distributed at the four corners, which is conducive to providing lateral support for the load monitor mechanism, further improving stability. The positioning seat is provided at the inner top of the anti-interference mechanism. During installation, the positioning seat is docked with the positioning pin for positioning, which is conducive to ensuring accurate installation effect, thereby improving installation accuracy and ensuring stable use in the later stage.

[0018] 3. In the present invention, the outer frame facilitates the connection and installation of the shock-absorbing spring piece and the buffer damping rod, and cooperates with the inner frame for further connection to provide an effective and stable connection, which is beneficial to provide effective buffering and shock absorption effect for the load monitoring instrument mechanism. At the same time, the shock-absorbing spring piece can provide a certain supporting force while providing buffering and shock absorption, ensuring stability, avoiding shaking, and providing effective shock absorption protection for the load monitoring instrument mechanism.

[0023] In this embodiment, the load monitor mechanism 1 is arranged inside the anti-interference mechanism 3, so that the anti-interference mechanism 3 can provide anti-electromagnetic interference protection when the load monitor mechanism 1 is running. The control panel 2 is arranged on the load monitor mechanism 1 to facilitate the provision of control operations.

[0024] The outer magnetic shielding cover 302 of the box and the outer magnetic shielding cover 308 of the cover are primarily designed to address high-frequency electromagnetic interference and are made of materials such as copper or aluminum. Metal materials have excellent reflection and conduction properties for high-frequency electromagnetic interference, reflecting or directing it to the ground, preventing it from entering the load monitor body. The middle magnetic shielding cover 303 of the box and the middle magnetic shielding cover 309 of the cover are used to shield electromagnetic interference in the mid-frequency band and are made of ferrite.

The inner magnetic shielding cover 304 of the box and the inner magnetic shielding cover 310 of the cover are located near the load monitor body and primarily block low-frequency electromagnetic interference. They are made of high-permeability Permalloy. Permalloy has high magnetic permeability in the low-frequency band and can effectively guide low-frequency magnetic fields, causing them to bypass the load monitor body and reduce the impact of low-frequency interference on internal electronic components. The optimized magnetic shield can more effectively shield electromagnetic interference of different frequencies, greatly reducing the interference to the electronic components inside the load monitor body. In a complex electromagnetic environment, the deviation of the collected data will be significantly reduced, which improves the accuracy and reliability of the load data and provides more reliable data support for subsequent power distribution optimization, fault location and other tasks. Reducing the impact of electromagnetic interference on the device helps to improve the stability and service life of the load monitor body. When electronic components work in a stable electromagnetic environment, the probability of failure can be reduced, equipment damage and maintenance costs caused by electromagnetic interference can be reduced, and the smooth progress of low-voltage electricity inspection work can be ensured. The magnetic shielding plate 311 is made of aluminum film and covers the top of the control panel 2, which is conducive to good reflection and conduction of electromagnetic interference at the position of the control panel 2. For electromagnetic interference with higher frequencies, the aluminum film can reflect it away, reducing interference entering the interior of the equipment.

[0025] The mounting rails 401 are arranged on both sides of the interior of the anti-interference mechanism 3, and the sliding blocks 410 are arranged on both sides of the exterior of the load monitor mechanism 1.

During the sliding process, the guiding effect is achieved by the cooperation of the guide strips 402 and the guide grooves 412, which is beneficial to improving the stability during sliding. During the sliding process, the handles 408 are pinched by the fingers to make the sliding blocks 407 slide toward each other inside the mounting tube 403. At the same time, the telescopic rod 405 and the spring member 406 are compressed to realize the extraction of the fixing pin 409. When the sliding block 410 is completely slid into the interior of the mounting rail 401, the fingers are released, and the elastic action of the spring member 406 is realized. It drives the telescopic rod 405 to extend, and then pushes the sliding block 407 to extend to both ends inside the mounting tube 403, and is inserted into the fixing hole 411 on the mounting rail 401 and the sliding block 410 through the fixing pin 409, thereby realizing a rapid limiting effect, which is beneficial to ensuring stability after installation. The side support blocks 413 are distributed at the four corners, which is beneficial to provide lateral support for the load monitor mechanism 1, further improving stability. The positioning seat 414 is provided at the inner top of the anti-interference mechanism 3, and the docking positioning with the positioning pin 415 during installation is beneficial to ensuring accurate installation effect, thereby improving installation accuracy and ensuring stable use in the later stage.

[0030] In the present invention, when the low-voltage power inspection and load identification device is in use, the load monitor mechanism 1 is first positioned within the anti-interference mechanism 3. The anti-interference mechanism 3 provides electromagnetic interference protection during operation. The control panel 2 is positioned on the load monitor mechanism 1 to facilitate control operations. The shock-absorbing seat 6 is positioned at the outer bottom of the anti-interference mechanism 3 to provide effective buffering protection during placement through its own damping.
