Since the outdoor pole-mounted circuit breaker has a large number of input terminals and output terminals, it takes a lot of time to install the temperature sensor. At the same time, the external connection wires of the temperature sensor are exposed and overlapped on the surface of the outdoor pole sensor, resulting in reduced safety. Summary of the invention

[0050] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0051] The embodiment of the present 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 shell 100 and a temperature measuring mechanism 200 and a second temperature measuring mechanism 300 respectively arranged on both sides of the integrated shell 100 and used to be connected to the input end or output end of the circuit breaker. The temperature measuring mechanism 200 and the second temperature measuring mechanism 300 have the same structure and can be connected to the input end or output end of the circuit breaker at will. The temperature measuring mechanism 200 and the second temperature measuring mechanism 300 have exactly the same structural size.

[0053] The setting of temperature measuring mechanism 1 200 and temperature measuring mechanism 2 300 is convenient for the inspector to install the temperature sensor 2111 to implement the temperature rise test of the circuit breaker. At the same time, the cable 205 connected to the terminal of the temperature sensor 2111 can be fixed on the surface of the cover plate 201, the second connecting rod 2203 and the first connecting rod 2202 by buckles. At the same time, the middle part of the cable 205 is set to be in the shape of a torsion spring, so that it can be deformed when the adjustment mechanism 2200 is actuated, thereby avoiding damage to the cable 205 caused by pulling.

[0054] Except for the metal strip 208, tension spring 2109, side spring 2107, bolts, fastening bolts 2206, copper mother tape 2110, and input connector 2105, which are made of metal, the rest are made of high-insulation and high-temperature resistant plastic materials. The specific material can be set according to the requirements of pressure resistance and heat resistance.

[0055] Reference Figure 1-Figure 3The temperature measuring mechanism 200 includes an adjusting mechanism 2200 for adjusting the position of the outer shell 203. The adjusting mechanism 2200 includes a connecting column 2201 inserted and fixed inside the mounting hole 101 on the surface of the integrated shell 100. The mounting holes 101 are arranged in an array on the surface of the integrated shell 100, and the number of the mounting holes 101 can be set according to the number of input terminals and output terminals of the circuit breaker. A through hole 102 is provided at the lower end of the mounting hole 101. The through hole 102 is connected to the outside and the mounting hole 101. A countersunk bolt 103 is movably inserted inside the through hole 102. The threaded end of the countersunk bolt 103 is connected to the connecting column 220. 1 is fixed by thread, and the head end face of the countersunk bolt 103 is flush with the surface of the integrated shell 100, one end of the connecting column 2201 is provided with a connecting rod 2202 by bolt rotation, and the connecting rod 2202 has a damping feeling when one end of the connecting column 2201 rotates, and both ends of the connecting column 2201 will deform under the tightening of the bolt to increase the friction with the surface of the connecting rod 2202 to generate a damping feeling so that the connecting rod 2202 can be fixed at a certain position, and one end of the connecting rod 2202 is provided with a connecting rod 2203 by bolt rotation, and the connecting rod 2203 has a damping feeling when one end of the connecting rod 2202 rotates When the bolts are tightened, the two ends of the connecting rod 1 2202 will be squeezed and deformed, thereby increasing the friction between the connecting rod 2203 and the connecting rod 2 to achieve a damping feeling. One end of the connecting rod 2203 is rotated by the fastening bolt 2206 and is provided with a connecting rod 3 2204. The fastening bolt 2206 is composed of a half-thread bolt and a nut. When the connecting rod 3 2204 rotates at one end of the connecting rod 2203, there is a damping feeling. The damping feeling is obtained by the fastening bolt 2206 squeezing the two sides of the connecting rod 2203, thereby increasing the friction between the connecting rod 2203 and the connecting rod 3 2204. The connecting rod 3 2204 is provided at one end of the connecting rod 2203. A long groove 2205 is provided for the rod of the fastening bolt 2206 to pass through, and the smooth surface of the half-thread bolt is located inside the long groove 2205. The connecting rod 2203 is located at one end of the connecting rod 3 2204 and is provided with a movable groove for the connecting rod 3 2204 to be plugged in. 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, a ball seat and other structures. The universal ball 2207 is an existing structure and will not be described in detail. A connecting shaft 2208 is fixed to one end of the steel ball of the universal ball 2207, and the connecting shaft 2208 is fixed to one side of the outer shell 203.

[0056] The inspector can install the connecting column 2201 according to the number of input terminals and output terminals of the outdoor column circuit breaker. When the user inserts the connecting column 2201 into the mounting hole 101, the through hole 102 is aligned with the threaded hole on the surface of the connecting column 2201. Then, the countersunk bolt 103 is rotated by a tool to connect and fix the integrated shell 100 with the multiple connecting columns 2201. The inspector manually moves the connecting rod 1 2202 to move it left and right at one end of the connecting column 2201, thereby adjusting the position of the outer shell 203. The user can also move the connecting rod 2203 to rotate it up and down at one end of the connecting rod 1 2202, and the position of the outer shell 203 can also be adjusted.

[0057] When the length of the connecting rod 3 2204 needs to be changed, the fastening bolt 2206 can be loosened first and the connecting rod 3 2204 can be pushed to move so that the long groove 2205 slides on the surface of the half-thread bolt, and then the fastening bolt 2206 can be locked by a tool to achieve damping or fix the connecting rod 3 2204 in a specified position. If the outer shell 203 is a little short of the input end or the output end of the circuit breaker, the fastening bolt 2206 can be adjusted to connect the metal strip 208 of the outer shell 203 to the input end or the output end of the circuit breaker. Then, the inspector can use his hands to pry the outer shell 203 to drive the connecting shaft 2208 to move. The connecting shaft 2208 drives the steel ball of the universal ball 2207 to rotate freely in the ball seat, thereby realizing the precise adjustment of the position of the outer shell 203, and then realizing precise plug-in installation. Through the adjustment structure, each connecting joint has a damping effect, so it can be shaped according to the needs of the inspector. The integrated shell 100 can be supported and suspended in the air to avoid contact with the circuit breaker, or the integrated shell 100 can be made to contact the circuit breaker as needed.

[0058] Reference Figure 4-Figure 6 The temperature measuring mechanism 200 also includes transverse grooves 2108 opened at both ends of the inner wall of the outer shell 203. The transverse grooves 2108 are set to be symmetrical in pairs, and the transverse grooves 2108 are set to be rectangular. A square rod 209 is slidably set between two opposite transverse grooves 2108. One half of the square rod 209 is fixed through the middle of the connecting plate 2112. A tension spring 2109 is fixed to the surface of 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 clamps 206 are always tightly attached. The lower end of the connecting plate 2112 is fixedly connected to one side of the upper end of the clamp 206 and is set in an "L" shape. The lower ends of the two clamps 206 close to each other are chamfered to facilitate the insertion of the input and output ends of the circuit breaker.

[0059] When the cylindrical input end of the circuit breaker is inserted between the clamps 206, it will be inserted between the arc-shaped openings 207 of the metal strips 208. Then, the inspector presses the two sides of the outer shell 203 with his hands to push the cylindrical input end toward the two metal strips 208, thereby pushing the two clamps 206 away from each other. The clamps 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 Figure 4-Figure 6 The upper end of the inner cavity of the outer shell 203 is slidably provided with an input connector 2105 that is connected to the external connection terminal and is used to transmit power. The structure of the input connector 2105 is as follows: Figure 5 As shown, it can be connected to a sleeve-shaped plug or to a plate-shaped connector by bolts. A longitudinal groove 2104 is provided on both sides of the inner cavity of the outer shell 203 at positions corresponding to the middle of the input connector 2105. A limit rod 2106 is longitudinally slidably arranged inside the longitudinal groove 2104. One end of the limit rod 2106 is fixedly connected to both sides of the input connector 2105. 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 to achieve a protective effect. When the limit rod 2106 abuts against the top of the longitudinal groove 2104, the input connector 2105 is moved out of the outer shell 203 to protrude and can be connected to the outer shell 203. The outer shell 203 is connected to the interface connecting terminal, and arc plates 2103 are rotatably arranged on both sides of the middle part of the inner cavity of the outer shell 203. The arc plates 2103 are used to drive the input connector 2105 to move longitudinally. Round rods 2100 are movably penetrated at both ends of the middle part of the inner wall of the outer shell 203, and one half of the round rod 2100 is fixedly penetrated and fixed to the middle part of the arc plate 2103. Under normal conditions, the end of the lower end of the arc plate 2103 abuts against the surface of the connecting plate 2112, and a clamping block 2114 is fixed on the facing ends of the two arc plates 2103. A conical surface 2113 is arranged at the lower end of the input connector 2105 for abutment, and the clamping block 2114 abuts against the conical surface 2113, and the contact surface between the clamping block 2114 and the conical surface 2113 is set to an arc shape to achieve better fitting and sliding.

[0061] When the connecting plate 2112 moves toward the outside, it will push 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 will be pushed to move upward, thereby moving the connecting end of the input connector 2105 out of the outer shell 203, and can be connected to the external connection terminal to realize power transmission.

[0062] Normally, the input connector 2105 is located inside the outer shell 203, and the input connector 2105 can be protected from damage when not in use.

[0063] Reference Figure 4-Figure 6 , clamping plates 206 for clamping the input or output end of the circuit breaker are slidably arranged at both ends of the lower side of the inner cavity of the outer shell 203, and metal strips 208 for conducting electricity are embedded and fixed at the ends facing each other of the two clamping plates 206. The metal strips 208 are made of copper. The specific installation structure of the clamping plates 206 and the metal strips 208 is shown in the attached Figure 6 The metal strip 208 is provided with an arc-shaped opening 207 for clamping the cylindrical output end or input end on one side of the tension spring 2109, and the two arc-shaped openings 207 can be spliced ​​into a circle. A rectangular groove 2102 for clamping the strip-shaped output end or input end is provided in the middle of the metal strip 208, and a rectangular groove 2102 is also provided at one end of the clamping plate 206. A socket 2101 is fixedly provided at the upper end of the metal strip 208, and the mounting end of the socket 2101 is fixed to the mounting end of the temperature sensor 2111, and the detection end of the temperature sensor 2111 abuts against the metal strip 208 to measure the temperature. A conductive copper mother tape 2110 is fixedly provided between one side of the upper ends of the two metal strips 208 and the lower end of the input connector 2105. The copper mother tape 2110 is provided with a redundant length, and no pulling will occur when the two sides of the metal strip 208 move and the input connector 2105 moves upward.

[0064] The metal strip 208 contacts the input or output of the circuit breaker to achieve circuit conduction. The arc-shaped opening 207 can wrap the cylindrical input or output to achieve better contact and avoid poor contact. The setting of the rectangular groove 2102 can insert the plate-shaped input or output into the rectangular groove 2102, thereby achieving firm fixation and avoiding looseness that causes poor contact. As the circuit breaker is powered on, the temperature of the input connection and the output connection will rise, and the increased temperature will be detected by the temperature sensor 2111 and transmitted through the cable 205.

[0065] Reference Figure 4-Figure 7 A temperature sensor 2111 for measuring the temperature of the metal strip 208 and the input end or the output end is provided at the upper end of one of the metal strips 208. 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 fixedly provided with an output main interface 400 fixedly connected to the output end of the hub 104.

[0066] The temperature sensor 2111 can detect the temperature of the connection points of each input end and output end, and then evaluate it through a computer to achieve the detection effect. Each cable 205 is fixedly connected to the input end of the 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 more tidy and thus achieving electrical safety.

[0067] Reference Figure 4 , Figure 5 A side spring 2107 is fixedly arranged between one end of the arc plate 2103 adjacent to the clamping block 2114 and the inner wall of the outer shell 203 . The side spring 2107 is arranged obliquely. A pull handle 204 is fixedly arranged on the opposite side of the two clamping plates 206 .

[0068] The arc plate 2103 will pull the side spring 2107 when rotating. Under the reaction force of the side spring 2107, one end of the arc plate 2103 can always be in contact with the connecting plate 2112 to prevent the arc plate 2103 from shaking. It should be noted that under normal circumstances, the two clamping blocks 2114 will not cause compression to the input connector 2105. At the same time, when storing the device, the conical surface 2113 needs to be always facing downward. When fixing the plate-shaped input end or output end, the user can pull the handle 204 to drive the two clamping plates 206 to separate, thereby realizing installation and making the operation more convenient.

[0069] Reference Figure 1 The upper end of the outer shell 203 is welded to the lower end of the cover plate 201, and the cover plate 201 is provided with a special-shaped groove 202 for the limit rod 2106 and the input connector 2105 to pass through.

[0070] The implementation principle of an outdoor pole-mounted circuit breaker detection device in the embodiment of the present application is:

[0071] The inspector connects each temperature measuring mechanism 1 200 to the input end of the circuit breaker, and connects each temperature measuring mechanism 2 300 to the output end of the circuit breaker, taking the columnar input end and output end as an example.

[0072] First, insert the cylindrical input end between the two arc-shaped openings 207. During the insertion process, the clamping plate 206 will be pushed, thereby driving the connecting plate 2112 and the square rod 209 to move. The connecting plate 2112 will push the arc-shaped plate 2103 to rotate, and then squeeze the conical surface 2113 on the surface of the input connector 2105 through the clamping block 2114, so that the input connector 2105 moves out of the outer shell 203 and can be connected to the external connection end. The current flows through the input connector 2105 to the copper mother tape 2110, then flows to the metal strip 208 and then to the input end of the circuit breaker. The cable 205 passing through the inside of the circuit breaker allows the current to flow from the output end of the circuit breaker. The circuit breaker usually has three input ends and output ends. The connecting wires of the three output ends are connected to the external load. During the installation process, the inspection personnel will adjust the angle of the universal ball 2207, the angle of the connecting rod three 2204 and the connecting rod two 2203, the angle of the connecting rod two 2203 and the connecting rod one 2202, and the angle of the connecting rod one 2202 and the connecting column 2201 in real time. By adjusting the setting of the mechanism 2200, the device can be installed on most outdoor column circuit breakers, thereby realizing detection and increasing the practicality of the device.

[0073] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
