Description

Technical Field

[0001] The present invention relates to the technical field of integrated power distribution measuring and controlling instruments, and in particular to an integrated power distribution measuring and controlling instrument. Background Art

[0002] The power distribution integrated measurement and control instrument adopts AC sampling technology. It is a new type of power distribution measurement and control equipment integrating data acquisition, communication, reactive power compensation and power grid parameter analysis. It is suitable for the detection and reactive power compensation controller of AC 0.4KV, 50Hz low-voltage power distribution system. The power distribution integrated measurement and control instrument needs to be installed outside the power distribution facility during installation to facilitate the monitoring of substations or distribution stations.

[0003] In some suburban wind power plants or solar power stations, since the equipment is widely distributed and outdoors, the corresponding power distribution integrated measurement and control instrument will be directly installed in the external environment through the mounting bracket. However, the power distribution integrated measurement and control instrument is easily affected by the external environment during use. For example, in rainy weather, there is a certain gap at the connection of the shell of the power distribution integrated measurement and control instrument. The shell connection is sealed by snapping, which leads to certain limitations in the sealing effect of the power distribution integrated measurement and control instrument. Rainwater can easily penetrate into the internal of the power distribution integrated measurement and control instrument through the gap between the shells, causing damage to the internal electrical components of the power distribution integrated measurement and control instrument, affecting the normal operation of the power distribution integrated measurement and control instrument, and reducing the use effect of the power distribution integrated measurement and control instrument. To this end, we propose a power distribution integrated measurement and control instrument.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing power distribution integrated measurement and control instruments on the market, and even if they can be solved, they need to be solved through external tools, which makes it impossible to achieve the desired effect.

The inner wall of the connecting frame 2103 and the inner wall of the second connecting frame 2104 are both provided with a diverter groove 2106, two first drainage grooves 2115 and two second drainage grooves 2116, the interior of each diverter groove 2106 is respectively connected with the interior of the two first drainage grooves 2115 and the interior of the two second drainage grooves 2116, the inner wall of the first connecting frame 2103 and the inner wall of the second connecting frame 2104 are both fixedly connected with a first sealing sheet 2107 and a second sealing sheet 2108, and the side surfaces of the two first sealing sheets 2107 that are close to each other are connected. The two second sealing sheets 2108 are in contact with each other, and the sides close to each other are in contact. By setting the drainage sealing unit 21, the water penetrating through the gap of the power distribution integrated measurement and control instrument can be effectively drained, and the waterproof effect of the power distribution integrated measurement and control instrument is further increased, and the comprehensive sealing effect of the power distribution integrated measurement and control instrument is achieved. The infiltrated rainwater can be drained through the diversion groove 2106, and the rainwater is effectively discharged through the first drainage groove 2115 and the second drainage groove 2116, thereby reducing the influence of external rainwater on the power distribution integrated measurement and control instrument and increasing its use effect;

The front of the fixed plate 314 and the back of the movable plate 313 are in contact with the outer surface of the TPU waterproof membrane coil 312. One end of each conical clamping column 315 penetrates the TPU waterproof membrane coil 312 and is clamped with the inside of the fixed plate 314. The right side of the pulling plate 311 is fixedly connected with three positioning rings 316. The inner wall of each positioning ring 316 is fixedly connected with three telescopic cylinders 318. One end of each telescopic cylinder 318 is fixedly connected with a trapezoidal clamping head 320. Each trapezoidal clamping head 320 is fixedly connected with the inner wall of each positioning ring 316. The outer surface of the shaped clamp 320 is fixedly connected with the inner wall of the positioning ring 316 by a rubber spring 317. By setting the isolation mechanism 3, the drainage sealing unit 21 and the dehumidification unit 22 can be cooperated to further increase the sealing and waterproof effect of the power distribution integrated measurement and control instrument, which is convenient for operating the power distribution integrated measurement and control instrument in rainy weather. By sealing and waterproofing the display screen of the power distribution integrated measurement and control instrument, the rainproof effect of the power distribution integrated measurement and control instrument can be increased without affecting the normal operation of the power distribution integrated measurement and control instrument, preventing rainwater from entering the interior through the display screen of the power distribution integrated measurement and control instrument, causing damage to electrical components;

[0049] The specific implementation method of this embodiment is as follows: when the display screen of the power distribution integrated measurement and control instrument needs to be waterproofed, the TPU waterproof membrane coil 312 is clamped onto the positioning rod 307 in advance, and then the plug-in rod 305 is clamped into the inside of the TPU waterproof membrane coil 312 through the sealing cover 301, and then the TPU waterproof membrane coil 312 is stretched to the right side of the power distribution integrated measurement and control instrument through the right side opening of the placement box 302 and the strip opening 306.

The trapezoidal clamping head 320 is squeezed inwardly by the force of the first conical block 309. The trapezoidal clamping head 320 squeezes the rubber spring 317 inwardly through the squeezing force and moves inwardly through the telescopic cylinder 318. When passing through the first conical block 309, the position at this time In the middle of the first conical block 309 and the second conical block 310, there is no squeezing force. The trapezoidal clamping head 320 is directly pushed by the elastic force of the rubber spring 317, so that it directly contacts the surface of the clamping column 308. At this time, it is limited by the first conical block 309, and the positioning ring 316 is effectively fixed on the clamping column 308. The TPU waterproof membrane coil 312 is directly attached to the display screen to protect the power distribution integrated measurement and control instrument from rain, so that the staff can operate the display screen in rainy weather, effectively increasing the sealing effect. When the use is completed and the pulling plate 311 needs to be pulled to the left, the pulling plate 311 is directly pulled to the right, and the pulling plate 311 continues to squeeze the trapezoidal clamping head 320. The trapezoidal clamping head 320 directly passes through the second conical block 3 10 reaches the right side of the second conical block 310, at which time the trapezoidal clamping head 320 is in contact with the outer conical surface of the second conical block 310, and the pulling plate 311 is directly pulled to the left, and the trapezoidal clamping head 320 directly drives the second conical block 310 to move to the left. When the second conical block 310 contacts the right side of the first conical block 309, the first conical block 309 and the second conical block 310 form a cone. At this time, the trapezoidal clamping head 320 can slide out directly through the second conical block 310 and the first conical block 309, and then open the movable plate 313, and tear off the used TPU waterproof membrane coil 312 along the perforated line on the TPU waterproof membrane coil 312. When it is used again, continue to repeat the above steps, which is effective for using the power distribution integrated measurement and control instrument in rainy weather.
