Description
Technical Field
[0001] This application relates to the field of circuit breakers, and more particularly to an outdoor pole-mounted circuit breaker detection device. Background Technology
[0002] Pole-mounted circuit breaker testing refers to a series of tests and inspections performed on pole-mounted circuit breakers to ensure their performance meets requirements and thus guarantees the stable operation of the power system. These tests include mechanical characteristic testing, electrical performance testing, visual inspection of the pole-mounted circuit breaker, and inspection of the operating mechanism. Pole-mounted circuit breaker testing is a comprehensive testing and inspection task designed to ensure the circuit breaker's performance meets requirements and thus guarantees the stable operation of the power system. During testing, operations must be strictly carried out in accordance with relevant standards and specifications to ensure the accuracy and reliability of the test results. Temperature rise testing is required during circuit breaker testing to detect the maximum temperature of each connection terminal.
[0003] Currently, when performing temperature rise detection on outdoor pole-mounted circuit breakers, several temperature sensors need to be manually fixed to the input and output terminals of the circuit breaker using cable ties. Since there are many input and output terminals on outdoor pole-mounted circuit breakers, a lot of time is required to install the temperature sensors. At the same time, the external connection wires of the temperature sensors are exposed and lapped on the surface of the outdoor pole sensor, which reduces safety. Summary of the Invention
[0004] To address the cumbersome operation of temperature rise detection, this application provides an outdoor pole-mounted circuit breaker detection device.
[0005] The outdoor pole-mounted circuit breaker detection device provided in this application adopts the following technical solution:
[0006] An outdoor pole-mounted circuit breaker detection device includes an integrated housing and a temperature measuring mechanism one and a temperature measuring mechanism two respectively disposed on both sides of the integrated housing and used to connect to the input or output end of the circuit breaker. The temperature measuring mechanism one and the temperature measuring mechanism two have the same structural dimensions.
[0007] The temperature measuring mechanism includes an adjustment mechanism for adjusting the position of the outer casing;
[0008] The upper end of the inner cavity of the outer shell is slidably provided with an input connector that is snapped into an external connection terminal and used for power transmission. The two sides of the middle part of the inner cavity of the outer shell are rotatably provided with arc-shaped plates for driving the longitudinal movement of the input connector. One end of the two arc-shaped plates facing each other is fixed with a clamping block that abuts against the tapered surface of the lower end of the input connector.
[0009] Under normal circumstances, the input connector is located inside the housing;
[0010] Both ends of the lower side of the inner cavity of the outer shell are slidably provided with clamping plates for holding the input or output end of the circuit breaker. A metal strip for conducting electricity is embedded and fixed in one end of the two clamping plates facing each other. A conductive copper strip is fixed between one side of the upper end of the two metal strips and the lower end of the input connector.
[0011] The upper end of the metal strip is provided with a temperature sensor for measuring the temperature of the metal strip and the input or output end. The cable of each temperature sensor passes through the outer shell and the integrated shell and is fixed to the hub inside the integrated shell. The upper end of the integrated shell is fixed with an output interface that is fixed to the output end of the hub.
[0012] By adopting the above technical solution, the metal strip is connected to the input or output terminal of the circuit breaker, so that the test current of the external power supply device is transmitted to the copper busbar through the input connector and then to the input terminal of the circuit breaker through the metal strip. At the same time, the connection between the metal strip and the input terminal of the circuit breaker will generate heat. The temperature sensor detects the temperature and transmits it to the hub through the cable. Then, it is transmitted to the computer for processing and temperature display through the output interface and external wires. The detection device can use existing products. The cable of the temperature sensor can be integrated with the first and second connecting rods and then through the hub and the output interface to avoid the cable tangling causing insulation damage and affecting electrical safety.
[0013] Preferably, the temperature measuring mechanism further includes transverse grooves formed at both ends of the inner wall of the outer shell, and a square rod slidably disposed between the two opposite transverse grooves and fixed through the middle of the connecting plate. A tension spring is fixed to one end of each square rod on the same side and one end of the transverse groove. The lower end of the connecting plate is fixed to one side of the upper end of the clamping plate.
[0014] By adopting the above technical solution, the transverse groove can guide and limit the movement of the square rod. The connecting plate can push the arc-shaped plate, and the tension spring can restore the two clamping plates to their original positions when no force is applied, thus enabling the next use.
[0015] Preferably, both ends of the inner wall of the outer shell are movably connected to round rods that are fixed through the middle of the arc-shaped plate;
[0016] Under normal conditions, the lower end of the arc-shaped plate abuts against the surface of the connecting plate, thereby causing the input connector to move synchronously with the connecting plate.
[0017] By adopting the above technical solution, the rotating arrangement of the round rod and the outer shell can make the arc plate rotate.
[0018] Preferably, the metal strip has an arc-shaped opening on one side of the tension spring for clamping the cylindrical output end or input end, and a rectangular groove for clamping the strip-shaped output end or input end is opened in the middle of the metal strip in the transverse direction. The upper end of the metal strip is fixed with a plug for fixing the temperature sensor.
[0019] By adopting the above technical solutions, the arc-shaped opening can be connected to the cylindrical input or output end, the rectangular groove can be connected to the plate-shaped input or output end, making the connection more stable, and the plug-in socket facilitates the maintenance of the temperature sensor.
[0020] Preferably, a side spring is fixed between one end of the arc-shaped plate near the clamping block and the inner wall of the outer shell, the side spring is inclined, and a handle is fixed on one side of the two clamping plates facing away from each other.
[0021] By adopting the above technical solution, the side spring can always be in contact with the surface of the connecting plate. The tilted side spring can prevent irregular deformation and damage. The side spring is compressed in the direction of rotation of the arc plate. The pull plate facilitates the connection between the clamping plate and the plate-shaped input or output end.
[0022] Preferably, longitudinal grooves are provided on both sides of the inner cavity of the outer shell at positions corresponding to the input connector, and a limiting rod that is fixedly connected to both sides of the input connector is slidably arranged in the longitudinal groove.
[0023] When the limit rod abuts against the bottom of the longitudinal groove, the input connector is located inside the outer casing.
[0024] By adopting the above technical solution, the longitudinal groove plays a guiding and limiting role for the limiting rod.
[0025] Preferably, a cover plate is fixedly provided at the upper end of the outer shell, and the cover plate has an irregular groove for the limiting rod and the input connector to pass through.
[0026] By adopting the above technical solution, the cover plate can protect the input connector, and the irregular groove will not interfere with the input connector being moved out of the housing, and will not affect the normal use of the device.
[0027] Preferably, the adjustment mechanism includes a connecting column inserted into a mounting hole fixed on the surface of the integrated shell. The lower end of the mounting hole has a through hole communicating with the outside. A countersunk bolt threaded to the connecting column is movably inserted into the through hole. A connecting rod is rotatably provided at one end of the connecting column through the bolt. The connecting rod has a damping feel when the connecting column rotates.
[0028] By adopting the above technical solution, the testing personnel can install the connecting column 2201 according to actual needs. The connecting column can be installed and fixed by the countersunk bolts, which is convenient for use and maintenance.
[0029] Preferably, a second connecting rod is rotatably mounted at one end of the first connecting rod via a bolt, and the second connecting rod has a damping feel when rotating at one end of the first connecting rod. A third connecting rod is rotatably mounted at one end of the second connecting rod via a fastening bolt, and the third connecting rod has a damping feel when rotating at one end of the second connecting rod. A long groove is provided at one end of the third connecting rod for the rod portion of the fastening bolt to pass through.
[0030] By adopting the above technical solution, the fastening bolts and bolts can provide damping between connecting rod one, connecting rod two and connecting rod three, which facilitates the use of the device.
[0031] Preferably, one end of the connecting rod three is fixed with a universal ball, and the movable end of the universal ball is fixed with a connecting shaft that is fixed to one side of the outer shell.
[0032] By adopting the above technical solution, and since the universal ball also has damping, the coupling is fixed only to a small part of the steel ball of the universal ball, thereby increasing the rotation angle of the coupling and enabling fine adjustment.
[0033] In summary, this application includes at least one of the following beneficial technical effects:
[0034] 1. The temperature measuring mechanism can be connected to the input or output of the circuit breaker, and can also be used to connect to the external test power supply.

[0050] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.
[0051] This application discloses an outdoor pole-mounted circuit breaker detection device.
[0052] Reference Figure 1 An outdoor pole-mounted circuit breaker detection device includes an integrated housing 100 and temperature measuring mechanism 200 and temperature measuring mechanism 300 respectively disposed on both sides of the integrated housing 100 for connection to the input or output end of the circuit breaker. Temperature measuring mechanism 200 and temperature measuring mechanism 300 have the same structure and can be arbitrarily connected to the input or output end of the circuit breaker. Temperature measuring mechanism 200 and temperature measuring mechanism 300 have the same structural dimensions.
[0053] The temperature measuring mechanism 1 200 and temperature measuring mechanism 2 300 are designed to facilitate the installation of temperature sensor 2111 by testing personnel to perform temperature rise testing on the circuit breaker. At the same time, the cable 205 connected to the terminal of temperature sensor 2111 can be fixed to the surface of cover plate 201, connecting rod 2203 and connecting rod 1 2202 respectively by clips. In addition, the middle part of cable 205 is set as a torsion spring, so that it can deform when the adjustment mechanism 2200 is activated, thus avoiding damage to cable 205 due to pulling.
[0054] Except for the metal strip 208, tension spring 2109, side spring 2107, bolt, fastening bolt 2206, copper female tape 2110, and input connector 2105, which are made of metal, all other components of this device are made of highly insulating and high-temperature resistant plastic. The specific materials can be set according to the requirements of pressure resistance and heat resistance.
[0055] Reference Figures 1-3The temperature measuring mechanism 200 includes an adjustment mechanism 2200 for adjusting the position of the housing 203. The adjustment mechanism 2200 includes a connecting post 2201 inserted into the mounting holes 101 fixed on the surface of the integrated housing 100. The mounting holes 101 are arrayed on the surface of the integrated housing 100, and the number of mounting holes 101 can be set according to the number of input and output terminals of the circuit breaker. A through hole 102 is provided at the lower end of the mounting hole 101, which communicates with the outside and the mounting hole 101. A countersunk bolt 103 is movably inserted into the through hole 102, and the threaded end of the countersunk bolt 103 is connected to the connecting post 2201. 1. The screw is fixed with the head of the countersunk bolt 103 flush with the surface of the integrated shell 100. One end of the connecting column 2201 is connected to a connecting rod 2202 via a bolt. The connecting rod 2202 provides a damping sensation when the connecting column 2201 rotates. The two ends of the connecting column 2201 deform under the tightening of the bolt, increasing the friction with the surface of the connecting rod 2202 and generating a damping sensation, which can fix the connecting rod 2202 in a certain position. One end of the connecting rod 2202 is connected to a connecting rod 2203 via a bolt. The connecting rod 2203 provides a damping sensation when the connecting rod 2202 rotates. When the bolt is tightened, it will compress and deform the two ends of the first connecting rod 2202, thereby increasing the friction between it and the second connecting rod 2203 to achieve a damping sensation. A third connecting rod 2204 is rotatably mounted at one end of the second connecting rod 2203 via a fastening bolt 2206. The fastening bolt 2206 consists of a threaded bolt and a nut. The third connecting rod 2204 provides a damping sensation when rotating at one end of the second connecting rod 2203. This damping sensation is obtained by the fastening bolt 2206 compressing both sides of the second connecting rod 2203, thereby increasing the friction between the second connecting rod 2203 and the third connecting rod 2204. The third connecting rod 2204 has a [feature / feature] located at one end of the second connecting rod 2203. The long groove 2205 through which the rod of the fastening bolt 2206 passes is provided. The smooth surface of the semi-threaded bolt is located inside the long groove 2205. The connecting rod 2203 is provided with a movable groove at one end of the connecting rod 3 2204 for the connecting rod 3 2204 to be inserted. The length of the movable groove is the same as the length of the long groove 2205. One end of the connecting rod 3 2204 is fixed to the ball seat of the universal ball 2207. The universal ball 2207 is composed of a steel ball and a ball seat. The universal ball 2207 is an existing structure and will not be described in detail. One end of the steel ball of the universal ball 2207 is fixed with a connecting shaft 2208. The connecting shaft 2208 is fixed to one side of the outer shell 203.
[0056] The inspector can install the connecting post 2201 according to the number of input and output terminals of the outdoor pole circuit breaker. When the user inserts the connecting post 2201 into the mounting hole 101, at the same time, the through hole 102 is aligned with the threaded hole on the surface of the connecting post 2201. Then, the countersunk bolt 103 is rotated with a tool to connect and fix the integrated housing 100 to multiple connecting posts 2201. The inspector can manually move the connecting rod 1 2202 left and right at one end of the connecting post 2201 to adjust the position of the housing 203. Alternatively, the inspector can move the connecting rod 2203 up and down at one end of the connecting rod 1 2202 to adjust the position of the housing 203.
[0057] When the length of connecting rod 2204 needs to be changed, the fastening bolt 2206 can be loosened first and the connecting rod 2204 can be moved to allow the long groove 2205 to slide on the surface of the semi-threaded bolt. Then, the fastening bolt 2206 can be tightened with a tool to achieve damping or fix the connecting rod 2204 in a specified position. If there is a slight difference between the housing 203 and the input or output end of the circuit breaker, the fastening bolt 2206 can be adjusted to connect the metal strip 208 of the housing 203 to the input or output end of the circuit breaker. Next, the testing personnel can manually pry open the outer shell 203, thereby moving the connecting shaft 2208. The connecting shaft 2208 causes the steel ball of the universal ball 2207 to rotate freely within the ball seat, thereby achieving precise adjustment of the position of the outer shell 203 and thus achieving precise plug-in installation. Through this adjustment structure, each connecting joint has a damping effect, so it can be shaped according to the needs of the testing personnel. The integrated shell 100 can be supported and suspended to avoid contact with the circuit breaker, or it can be made to contact the circuit breaker as needed.
[0058] Reference Figures 4-6 The temperature measuring mechanism 200 also includes transverse grooves 2108 formed at both ends of the inner wall of the outer casing 203. The transverse grooves 2108 are arranged symmetrically in pairs and are rectangular. A square rod 209 is slidably arranged between the two opposite transverse grooves 2108. Half of the square rod 209 is fixed through the middle of the connecting plate 2112. A tension spring 2109 is fixed to one end of the same side of each square rod 209 and one end of the transverse groove 2108. Under the action of the tension spring 2109, the two clamping plates 206 are always tightly attached. The lower end of the connecting plate 2112 is fixed to one side of the upper end of the clamping plate 206 and is arranged in an "L" shape. The lower ends of the two clamping plates 206 on the side closest to each other are provided with chamfers to facilitate the insertion of the input and output terminals of the circuit breaker.
[0059] When the input terminal of the circuit breaker column is inserted between the clamping plates 206, it will be inserted between the arc-shaped openings 207 of the metal strip 208. Then, the tester presses the two sides of the outer shell 203 with his hand to push the column input terminal against the two metal strips 208 to both sides, thereby pushing the two clamping plates 206 away from each other. The clamping plates 206 drive the connecting plate 2112 and the square rod 209 to move. The square rod 209 moves in the transverse groove 2108 and pulls the tension spring 2109 to deform.
[0060] Reference Figures 4-6 An input connector 2105, which is slidably disposed at the upper end of the inner cavity of the outer casing 203 and is used for connecting to external terminals and transmitting power, is described below. Figure 5 As shown, it can be connected to a sleeve-shaped plug or a plate-shaped connector via bolts. Longitudinal grooves 2104 are formed on both sides of the inner cavity of the outer shell 203, corresponding to the middle of the input connector 2105. A limit rod 2106 is longitudinally slidably installed inside the longitudinal groove 2104. One end of the limit rod 2106 is fixedly connected to both sides of the input connector 2105, and the end face of the limit rod 2106 away from the input connector 2105 is flush with the surface of the outer shell 203. When the limit rod 2106 abuts against the bottom of the longitudinal groove 2104, the input connector 2105 is located inside the outer shell 203, thus achieving a protective effect. When the limit rod 2106 abuts against the top of the longitudinal groove 2104, the input connector 2105 moves out of the outer shell 203, protruding and allowing it to connect with the outer shell. The interface is connected to the terminal block. Arc-shaped plates 2103 are rotatably arranged on both sides of the inner cavity of the outer shell 203. The arc-shaped plates 2103 are used to drive the input connector 2105 to move longitudinally. Round rods 2100 are movably inserted through both ends of the inner wall of the outer shell 203. Half of the round rods 2100 are fixed through the middle of the arc-shaped plates 2103. Under normal conditions, the lower end of the arc-shaped plates 2103 abuts against the surface of the connecting plate 2112. Clamping blocks 2114 are fixed at the opposite ends of the two arc-shaped plates 2103. The lower end of the input connector 2105 is provided with a conical surface 2113 that abuts against it. The clamping blocks 2114 abut against the conical surface 2113, and the contact surface between the clamping blocks 2114 and the conical surface 2113 is set to be arc-shaped to achieve better contact and sliding.
[0061] When the connecting plate 2112 moves outward, it pushes the arc plate 2103 to rotate around the round rod 2100. At the same time, the end of the arc plate 2103 slides on the surface of the connecting plate 2112, and the other end of the arc plate 2103 pushes the clamping block 2114 to move downward while sliding on the surface of the conical surface 2113. When the two clamping blocks 2114 approach each other, the input connector 2105 is pushed upward, thereby causing the connecting end of the input connector 2105 to move out of the outer casing 203, so that it can be connected to the external connection terminal to realize the transmission of electricity.
[0062] Under normal circumstances, the input connector 2105 is located inside the housing 203, and can be protected from damage when not in use.
[0063] Reference Figures 4-6 Both ends of the lower side of the inner cavity of the outer casing 203 are slidably equipped with clamping plates 206 for holding the input or output end of the circuit breaker. A conductive metal strip 208 is embedded and fixed at one end of each clamping plate 206 facing each other. The metal strip 208 is made of copper. The specific installation structure of the clamping plates 206 and the metal strip 208 is shown in the attached diagram. Figure 6 The metal strip 208 is located on one side of the tension spring 2109 and has an arc-shaped opening 207 for clamping the cylindrical output or input end. The two arc-shaped openings 207 can be spliced into a circle. The metal strip 208 has a rectangular groove 2102 in the middle of its transverse direction for clamping the strip-shaped output or input end. One end of the clamping plate 206 is also provided with a rectangular groove 2102. The upper end of the metal strip 208 is fixed with a plug-in seat 2101. The mounting end of the plug-in seat 2101 is fixed with the mounting end of the temperature sensor 2111, and the detection end of the temperature sensor 2111 abuts against the metal strip 208 to realize temperature measurement. A conductive copper mother strip 2110 is fixed between one side of the upper end of the two metal strips 208 and the lower end of the input connector 2105. The copper mother strip 2110 is provided with redundant length so that it will not be pulled when the metal strips 208 move to both sides or the input connector 2105 moves upward.
[0064] The metal strip 208 can make the circuit conduction by contacting the input or output end of the circuit breaker. The arc-shaped opening 207 can wrap the cylindrical input or output end to achieve better contact and avoid poor contact. The rectangular slot 2102 can be used to insert the plate-shaped input or output end into the rectangular slot 2102 to achieve firm fixation and avoid loosening that would lead to poor contact. As the circuit breaker is powered on, the temperature at the connection between its input end and the connection between its output end will rise. The temperature rise will be detected by the temperature sensor 2111 and transmitted through the cable 205.
[0065] Reference Figures 4-7 The upper end of the metal strip 208 is provided with a temperature sensor 2111 for measuring the temperature of the metal strip 208 and the input or output end. The cable 205 of each temperature sensor 2111 passes through the outer shell 203 and the integrated shell 100 respectively and is fixed to the hub 104 inside the integrated shell 100. The upper end of the integrated shell 100 is fixed with an output interface 400 that is fixed to the output end of the hub 104.
[0066] Temperature sensor 2111 can detect the temperature at the connection points of each input and output terminal, and then evaluate it through a computer to achieve the detection effect. Each cable 205 is fixedly connected to the input terminal of hub 104, and the temperature detected by each temperature sensor 2111 is transmitted through the output main interface 400. The external main cable is connected to the output main interface 400. This setting can centrally organize the cables 205 of multiple temperature sensors 2111, making the device neater and thus achieving electrical safety.
[0067] Reference Figure 4 , Figure 5 A side spring 2107 is fixed between one end of the arc plate 2103 near the clamping block 2114 and the inner wall of the outer shell 203. The side spring 2107 is inclined. A handle 204 is fixed on one side of the two clamping plates 206 opposite to each other.
[0068] When the curved plate 2103 rotates, it pulls the side spring 2107. Under the reaction force of the side spring 2107, one end of the curved plate 2103 can always be in contact with the connecting plate 2112 to prevent the curved plate 2103 from shaking. It should be noted that under normal conditions, the two clamps 2114 will not squeeze the input connector 2105. At the same time, when storing the device, the conical surface 2113 should always face downward. When fixing the plate-shaped input or output end, the user can pull the handle 204 to separate the two clamps 206, thereby realizing the installation and making the operation more convenient.
[0069] Reference Figure 1 The upper end of the outer shell 203 is fused to the lower end of the cover plate 201. The cover plate 201 has a shaped groove 202 for the limit rod 2106 and the input connector 2105 to pass through.
[0070] The implementation principle of the outdoor pole-mounted circuit breaker detection device in this application embodiment is as follows:
[0071] The testing personnel connected each temperature measuring device 200 to the input terminal of the circuit breaker, and the temperature measuring device 300 to the output terminal of the circuit breaker, taking the cylindrical input and output terminals as an example.
[0072] First, the cylindrical input end is inserted between the two arc-shaped openings 207. During insertion, the clamping plate 206 is pushed, which in turn moves the connecting plate 2112 and the square rod 209. The connecting plate 2112 pushes the arc-shaped plate 2103 to rotate, which in turn squeezes the conical surface 2113 of the input connector 2105 through the clamping block 2114, thereby moving the input connector 2105 out of the outer casing 203 so that it can be connected to the external connection terminal. The current flows through the input connector 2105 to the copper female strip 2110, then to the metal strip 208, and finally to the input end of the circuit breaker. The cable 205 inside the circuit breaker allows current to flow from the output terminal of the circuit breaker. The circuit breaker usually has three input terminals and three output terminals.
