They are mainly used to monitor parameters such as power grid frequency, harmonics, voltage fluctuations, and flicker in real time. There are two common types: portable testers, used for on-site testing and diagnosis, and online monitors, which support remote data transmission and long-term recording.

[0003] However, the common installation method for online power quality monitoring devices on the market is to install them on the door of the power cabinet, drill a hole and embed them into the door for fixation. This is convenient for operation and viewing, but after wiring, repeated opening and closing of the cabinet door will cause the wiring to be pulled. Prolonged pulling or excessive pulling force can easily cause the wiring to come loose, leading to electrical safety issues. Utility Model Content

An adjusting screw is rotatably installed on both ends of the fixing plate. A threaded tube is threadedly connected to one end of the adjusting screw. Two threaded tubes at the same height are welded to both ends of the movable pull plate. A flexible rubber plate is glued to one end of the movable pull plate. Two flexible rubber plates are glued to the top and bottom ends of the clamping frame, respectively. The clamping frame has guide openings at both the top and bottom. The two guide openings are slidably engaged with the two ends of the clamping rod. Limit screws are installed at both ends of the clamping rod through screw holes.

[0008] According to the above technical solution, a heat dissipation assembly is installed at the other end of the main body of the detector, and the heat dissipation assembly includes a flow guide ring; A flow guide ring is fitted onto the end of the detector body away from the fixed plate. A fan box is welded to the top of the flow guide ring, and a fan is embedded inside the fan box. An exhaust pipe is installed at one end of the fan box, and an air inlet pipe is connected to the bottom of the flow guide ring. Filters are installed at one end of both the exhaust pipe and the air inlet pipe. Thermally conductive copper sheets are evenly welded to both sides of the flow guide ring near the detector body.

[0009] According to the above technical solution, the thermally conductive copper sheet is attached to the side of the main body of the detector, and one end of the thermally conductive copper sheet is aligned with the end of the main body of the detector.

Equipped with a wiring limit component, the connecting wire to be connected is passed through the gap between the clamping rods. The clamping rods are pulled and slid along the guide opening until the anti-slip rubber strip on the side of the clamping rod clamps the connecting wire. The end of the limit screw presses against the top of the guide opening to fix the clamping rod. Finally, the adjusting screw is rotated, and the threaded tube is pulled along the adjusting screw to move the movable pull plate closer to the fixed plate. During this process, the distance between the main body of the detector and the clamping frame is shortened, the connecting wire between the main body of the detector and the clamping frame is bent, and the flexible rubber plate is tightened.

A fixing plate 201 is installed on the top and bottom surfaces of one end of the main body 1 of the detector. An adjusting screw 202 is rotatably installed through both ends of the fixing plate 201. A threaded tube 203 is threadedly connected to one end of the adjusting screw 202. Two threaded tubes 203 at the same height are welded to both ends of the movable pull plate 204. A flexible rubber plate 205 is glued to one end of the movable pull plate 204. The fixing plate 201, the movable pull plate 204 and the flexible rubber plate 205 are all the same length. The fixing plate 201, the movable pull plate 204 and the flexible rubber plate 205 are all flush with the side of the main body 1 of the detector, so that the flexible rubber plate 205 can deform and buffer the impact of pulling. The two flexible rubber plates 205 are glued to the top and bottom ends of the clamping frame 206 respectively. The clamping frame 206 has guide openings 207 at both the top and bottom. The two guide openings 207 are slidably engaged with the two ends of the clamping rod 208. There are several clamping rods 208, which are parallel to each other to facilitate clamping the connecting wire. Limit screws 209 are installed at both ends of the clamping rod 208 through screw holes. Anti-slip strips 210 are glued to both sides of the clamping rod 208.

[0017] The other end of the main body 1 of the detector is equipped with a heat transfer assembly 3, which includes a guide ring 301, a fan box 302, a fan 303, an exhaust pipe 304, an inlet pipe 305, a filter screen 306, and a thermally conductive copper sheet 307. A flow guide ring 301 is fitted onto the end of the main body 1 of the detector away from the fixed plate 201. A fan box 302 is welded to the top of the flow guide ring 301, and a fan 303 is embedded inside the fan box 302. An exhaust pipe 304 is installed at one end of the fan box 302. The input end of the fan 303 is electrically connected to the output end of the external power supply. Air outlet holes are evenly opened on the outside of the fan 303, and the air outlet holes are connected to the exhaust pipe 304 to ensure the normal operation of the fan 303. An air inlet pipe 305 is connected to the bottom end of the flow guide ring 301. A filter screen 306 is installed at one end of both the exhaust pipe 304 and the air inlet pipe 305. Thermally conductive copper sheets 307 are evenly welded to both sides of the flow guide ring 301 near the main body 1 of the detector. The thermally conductive copper sheets 307 are attached to the side of the main body 1 of the detector, and one end of the thermally conductive copper sheets 307 is aligned with the end of the main body 1 of the detector to improve the efficiency of heat transfer.

[0018] The working principle and usage process of this utility model are as follows: The main body 1 of the detector is embedded in the door of the power cabinet, and the connecting wire to be connected is passed through the gap between the clamping rods 208. Then, the clamping rods 208 are pulled and slid along the guide port 207 until the anti-slip rubber strip 210 on the side of the clamping rods 208 clamps the connecting wire. Next, the limiting screw 209 is rotated, and the end of the limiting screw 209 presses against the top of the guide port 207 to fix the clamping rods 208 and prevent them from sliding freely, thus fixing the connecting wire. Finally, the adjusting screw 202 is rotated, and the threaded tube 203 is pulled along the adjusting screw 202 to slide, and the movable pull plate 204 is moved closer to the fixed plate 201. During this process, the distance between the main body 1 of the detector and the clamping frame 206 is shortened, the connecting wire between the main body 1 of the detector and the clamping frame 206 is bent, and the flexible rubber plate 205 is tightened. When the cabinet door is opened, if the pulling amplitude is large, the connecting wire may be pulled. The bent connecting wire between the main body 1 of the detector and the clamp 206 will be reset, and the flexible rubber plate 205 will deform and lengthen to buffer the impact force of the cabinet door opening, prevent the wiring position from loosening, prevent the connecting wire from falling off, and ensure the integrity of the wiring. If the temperature of the detector body 1 rises after prolonged use, the fan 303 will be activated, reducing the air pressure inside the fan box 302. The fan 303 will drive the airflow through the guide ring 301. The air enters through the air inlet pipe 305, flows upward along the guide ring 301 to the fan box 302, and is then discharged through the exhaust pipe 304. During this process, the heat from the detector body 1 will be transferred to the flowing air through the heat-conducting copper sheet 307, carrying the heat out and dissipating it to the outside, thereby reducing the temperature of the equipment. Furthermore, the air only flows outside the detector body 1 and will not enter the power cabinet, thus avoiding affecting other electrical equipment. The cooling is effective and safe. The main body of the detector can be selected as model APView400.
