Description

Technical Field

[0001] This utility model belongs to the field of storage cabinet technology, specifically a power quality interference source tolerance testing device. Background Technology

[0002] A power quality interference source tolerance test device is a device used to evaluate the tolerance of electrical equipment or systems to various power quality interference sources. A common power quality interference source tolerance test device is a power quality analyzer.

[0003] Power quality analyzers can detect various power quality parameters such as voltage, current, frequency, harmonic voltage content, and three-phase voltage imbalance. They can accurately measure electrical parameters, display vector diagrams of the measured voltage and current, and analyze the correctness of metering equipment wiring. They can measure and analyze the AC power quality from the public power grid to the user end, including frequency deviation, voltage deviation, voltage fluctuation, flicker, permissible three-phase voltage imbalance, and grid harmonics.

[0004] When not in use, the power quality analyzer is separate from its data detection cable, leaving the data interface exposed. Prolonged exposure can lead to oxidation of the data interface surface and increased contact resistance, resulting in severe signal attenuation during data transmission, causing data loss, bit errors, and ultimately affecting the accuracy of the power quality analyzer's measurement and analysis. Furthermore, dust and other impurities can easily enter the exposed data interface, accumulating inside and affecting its appearance. This not only detracts from the interface's cleanliness but also hinders proper contact between the interface and the cable, leading to poor connection.

[0005] Therefore, this utility model provides a power quality interference source tolerance testing device. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A power quality interference source tolerance testing device of this utility model includes a power quality analyzer. A data interface is provided on the top of the power quality analyzer. A fixing sleeve is fixedly installed on the side of the power quality analyzer near the data interface, covering the data interface. Two symmetrically arranged baffles are provided inside the fixing sleeve. An arc-shaped fixing block is fixedly installed on the side of the baffles away from the data interface. Several rubber guide posts are rotatably connected to the arc-shaped surface of the fixing block. Two symmetrically arranged sliding rods are slidably connected inside the fixing sleeve. A spring is fixedly installed between the sliding rods and the fixing sleeve, and one end of the sliding rod is fixedly connected to the fixing block.

[0008] Furthermore, two symmetrically arranged elastic balls are fixedly installed inside the fixed sleeve, and an air outlet pipe connected to the inside is fixedly installed on one side of each elastic ball.

[0009] Furthermore, two arc-shaped auxiliary plates are fixedly installed on one side of the fixing block, and a pressure plate is fixedly installed between the two auxiliary plates.

[0010] Furthermore, the fixed sleeve has an internal groove that communicates with the outside, and a filter frame is fixedly installed in the groove.

[0011] Furthermore, a rotating rod is rotatably connected inside the filter frame via a torsion spring, and several balls made of flexible material are rotatably connected to the surface of the rotating rod.

[0012] Furthermore, a horn-shaped guide ring is fixedly installed at the end of the fixed sleeve away from the power quality analyzer, and several guide balls are wedged at the end of the guide ring away from the fixed sleeve.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The power quality interference source tolerance testing device of this utility model moves the data detection line towards the data interface. A flared guide ring and several guide balls quickly guide the data detection line into a fixed ring, facilitating rapid alignment of the data detection line with the data interface. As the data detection line continues to extend into the fixed ring, one end of the line contacts several guide posts on an arc-shaped fixed block, squeezing and pushing two fixed blocks and two baffles to slide away from each other. Supported by a sliding rod, the fixed blocks and baffles slide and compress a spring, allowing the end of the data detection line to quickly insert into the data interface. When the data interface is no longer in use and the data detection line is pulled out, the baffles and fixed blocks quickly reset under the action of the sliding rod and spring, thus closing the data interface for protection. This designed structure achieves rapid closure and protection of the data interface, reducing the time the data interface is exposed, thereby reducing surface oxidation and increased contact resistance, and minimizing the entry of dust and impurities into the data interface, thus reducing the occurrence of poor contact with the data detection line.

[0015] 2. The power quality interference source tolerance testing device of this utility model, when the data detection line enters the fixed sleeve, squeezes the rotating rod, causing the rotating rod to carry several balls that impact the filter frame, thereby vibrating the filter frame and ensuring the permeability of the filter frame pores. As the data detection line continues to move and squeezes the fixed block, the fixed block, along with the auxiliary plate and pressure plate, squeezes the elastic balls, causing the gas inside the elastic ring to blow towards the port of the data detection line, thereby pre-cleaning the data detection line and reducing the impact of internal dust and impurities when the data detection line is connected to the data interface. At the same time, the blown-off impurities will fall out of the fixed sleeve through the filter frame in the through groove. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5As shown in the embodiment of this utility model, a power quality interference source tolerance testing device includes a power quality analyzer 1, with a data interface 2 on the top of the power quality analyzer 1. A fixing sleeve 3 is fixedly installed on the side of the power quality analyzer 1 near the data interface 2, covering the data interface 2. Inside the fixing sleeve 3, there are two symmetrically arranged baffles 4. An arc-shaped fixing block 5 is fixedly installed on the side of the baffles 4 away from the data interface 2. Several rubber guide posts 6 are rotatably connected to the arc-shaped surface of the fixing block 5. Inside the fixing sleeve 3, there are two symmetrically arranged sliding rods 7. A spring 8 is fixedly installed between the sliding rods 7 and the fixing sleeve 3, and one end of the sliding rod 7 is fixedly connected to the fixing block 5. A trumpet-shaped guide ring 17 is fixedly installed on the end of the fixing sleeve 3 away from the power quality analyzer 1, and several guide balls 18 are wedged on the end of the guide ring 17 away from the fixing sleeve 3.

[0025] When using the power quality analyzer 1, the data detection cable needs to be connected to the data interface 2. First, place the power quality analyzer 1 horizontally. Then, move the data detection cable towards the data interface 2. The flared guide ring 17 and several guide balls 18 quickly guide the data detection cable into the fixing ring, facilitating rapid alignment of the data detection cable with the data interface 2. As the data detection cable continues to extend into the fixing ring, one end of the cable contacts several guide posts 6 on the arc-shaped fixing block 5, squeezing and pushing the two fixing blocks 5 and two baffles 4 to slide away from each other. Supported by the slide rod 7, the fixing blocks 5 and baffles 4 slide and compress the spring 8, allowing the end of the data detection cable to quickly insert into the data interface 2. When the data interface 2 is no longer in use and the data detection cable is pulled out, the baffles 4 and fixing blocks 5 quickly reset under the action of the slide rod 7 and spring 8, thus closing the data interface 2 for protection.

[0026] The structure designed above enables rapid closure and protection of the data interface 2, reducing the time the data interface 2 is exposed to the outside, thereby reducing surface oxidation and increased contact resistance of the data interface 2. At the same time, it reduces the entry of dust and impurities into the data interface 2, thereby reducing the occurrence of poor contact with the data detection line.

[0027] Two symmetrically arranged elastic balls 9 are fixedly installed inside the fixed sleeve 3. An air outlet pipe 10 connected to the inside is fixedly installed on one side of the elastic ball 9. Two arc-shaped auxiliary plates 12 are fixedly installed on one side of the fixed block 5. A pressure plate 11 is fixedly installed between the two auxiliary plates 12.

[0028] Specifically, the fixed sleeve 3 has a through groove 13 that communicates with the outside. A filter frame 14 is fixedly installed in the through groove 13. A rotating rod 15 is rotatably connected to the filter frame 14 through a torsion spring. Several flexible ball bearings 16 are rotatably connected to the surface of the rotating rod 15.

[0029] During operation, when the data detection line enters the fixed sleeve 3, it squeezes the rotating rod 15, causing the rotating rod 15 to carry several balls 16 to impact the filter frame 14, thus vibrating the filter frame 14 and ensuring the permeability of the filter frame 14's pores. As the data detection line continues to move and squeezes the fixed block 5, the fixed block 5, along with the auxiliary plate 12 and pressure plate 11, squeezes the elastic ball 9, causing the air inside the elastic ring to blow towards the port of the data detection line, thereby pre-cleaning the data detection line and reducing the impact of internal dust and impurities when the data detection line is connected to the data interface 2. At the same time, the blown-off impurities will fall out of the fixed sleeve 3 through the filter frame 14 in the through groove 13.

[0030] Working Principle: When using the power quality analyzer 1, the data detection cable needs to be connected to the data interface 2. First, place the power quality analyzer 1 horizontally. Then, move the data detection cable towards the data interface 2. The flared guide ring 17 and several guide balls 18 quickly guide the data detection cable into the fixed ring, facilitating its alignment with the data interface 2. As the data detection cable continues to extend into the fixed ring, one end contacts several guide posts 6 on the arc-shaped fixed block 5, squeezing and pushing the two fixed blocks 5 and two baffles 4 to slide away from each other. Supported by the slide rod 7, the fixed blocks 5 and baffles 4 slide and compress the spring 8, allowing the end of the data detection cable to quickly insert into the data interface 2. When the data interface 2 is no longer in use and the data detection cable is pulled out, the baffles 4 and fixed blocks 5 quickly reset under the action of the slide rod 7 and spring 8, thus closing the data interface 2 for protection.

[0031] When the data detection line enters the fixed sleeve 3, it squeezes the rotating rod 15, causing the rotating rod 15 to carry several balls 16 to impact the filter frame 14, thereby causing the filter frame 14 to vibrate and ensuring the permeability of the filter frame 14's pores. As the data detection line continues to move and squeezes the fixed block 5, the fixed block 5, along with the auxiliary plate 12 and pressure plate 11, squeezes the elastic ball 9, causing the air inside the elastic ring to blow towards the port of the data detection line, thus achieving pre-cleaning of the data detection line.
