[0001] The present invention relates to the technical field of miniature circuit breakers, and in particular to an intelligent miniature circuit breaker with a remote control function. Background Art

[0002] Miniature circuit breakers are the most widely used terminal protection devices in building electrical terminal distribution devices. They are used for short circuit, overload, overvoltage and other protection of single-phase and three-phase circuits below 125A. They include single-pole 1P, two-pole 2P, three-pole 3P and four-pole 4P. Circuit breakers can connect, carry and disconnect currents under normal circuit conditions, and can also connect, carry a certain time and disconnect currents under specified abnormal circuit conditions. With the continuous development of society, the application of miniature circuit breakers is increasing, and the types of miniature circuit breakers are also increasing. However, some miniature circuit breakers are tripping. After the gate is turned off, it is reset manually. Due to the high installation position of the miniature circuit breaker, the operation is inconvenient, and the remote intelligent control automatic operation cannot be well performed.

When the device is used, when the installation position of the device is narrow and inconvenient to connect to the external circuit, the position of the miniature circuit breaker 1 can be adjusted to a degree that is convenient for wiring. The operation is simple and convenient. The upper and lower ends of the miniature circuit breaker 1 are provided with sealing devices 4. The sealing device 4 includes a bracket 401. The upper and lower ends of the outer side of the miniature circuit breaker 1 are slidably connected with the bracket 401. The inner left end of the bracket 401 is close to the center line of the miniature circuit breaker 1.

When using the device, when the connecting line is connected, the connecting end of the device connecting line can be sealed, thereby avoiding the phenomenon of rapid oxidation of the connecting end of the connecting line and ensuring the normal connection of the device.

[0028] Working process: All electrical appliances in the device are powered by the battery 202. When using the device, first clamp the bracket 401 at the upper and lower ends of the miniature circuit breaker 1, so that the limit shaft 402 and the positioning rod 403 both pass through the bracket 401, and then rotate the positioning rod 403 to make it rotate ninety degrees. At this time, under the action of the inclined surface on the outside of the positioning rod 403, the positioning rod 403 will compress the fifth spring 405, and the fixed shaft 404 will continue to slide with the positioning rod 403. When the positioning rod 403 completes the rotation, under the elastic force of the fifth spring 405, the bracket 401 is stably installed. After installation, cover the fixed cover 201 on the left end of the outside of the miniature circuit breaker 1 so that it is limited by the limit block 210. In the process of continuously pushing the fixed cover 201 to the right, the bottom The limiting block 210 will continuously contact the first card block 211, and the first card block 211 will continuously compress the second spring 213. When the first card block 211 is reset to the inner side of the limiting block 210 at the bottom, the installation of the intelligent control mechanism is completed. When it needs to be removed, it is only necessary to pull the pull rod 212 downward, and the intelligent control mechanism can be removed by pulling the left. The operation is simple and convenient. After completing the above operations, when installing the device, the device is limited to the track of the positioning mechanism through the fixing seat 301. At this time, the top right side of the fixing seat 301 is first hung on the positioning track, and then the bottom of the device is pressed. At this time, the fixing block 307 will first compress the fourth spring 306. When the fixing block 307 is reset again under the recovery of the elastic force of the fourth spring 306, at this time After the device is installed, when the installation position of the miniature circuit breaker 1 is relatively narrow, when connecting the top, first press the miniature circuit breaker 1 so that the pressure block 303 pushes the positioning block 304. At this time, the positioning block 304 will compress the third spring 305. When the positioning block 304 is completely retracted into the fixing seat 301, pull the miniature circuit breaker 1 downward. At this time, the fixing sleeve 302 will slide downward in the fixing seat 301. When it slides to the point where it is convenient to connect the connecting wire at the top, the connecting wire is inserted into the connecting hole at the top of the miniature circuit breaker 1 through the bracket 401, and then the connecting wire is connected. After the connection is completed, reset the miniature circuit breaker 1. Because the upper and lower right sides of the fixing sleeve 302 are inclined, the positioning block 304 will not affect the sliding of the fixing sleeve 302, and directly push The miniature circuit breaker 1 can be reset. After resetting, the same operation as above is performed to push the miniature circuit breaker 1 upward to connect the connecting wire at the bottom. After the connection is completed, the second threaded shaft 408 is rotated. At this time, the connecting block 406 will drive the rubber sealing block 407 to seal the wiring port, thereby avoiding the phenomenon of rapid aging at the wiring point. When the sealing setting of the wiring hole is completed, the device can be used by starting the device through the controller 203. When the device trips, the operating lever on the left side of the miniature circuit breaker 1 will rotate downward to trigger the control switch 209. At this time, the controller 203 will upload an alarm signal to the control terminal, so as to facilitate the first time to determine the tripping fault. After the repair is completed, the controller 203 is controlled by the remote control terminal.Thus, the control motor 204 drives the first threaded shaft 205 to rotate clockwise, and at this time, the slider 206 drives the support block 208 to reset the operating rod of the miniature circuit breaker 1 upward. When the support block 208 contacts the miniature circuit breaker 1, the support block 208 will continuously compress and reset the first spring 207, and the support block 208 will continuously slide with the slider 206. When the operating rod of the miniature circuit breaker 1 is reset, the control motor 204 rotates counterclockwise to reset the control switch 209.

[0029] Embodiment 2:

[0030] The same parts as those in Example 1 will not be repeated in Example 2. The difference is as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The present invention provides a technical solution: a second clamping block 214 is slidably connected to the bottom inner end of the limit block 210 at the bottom, and the second clamping block 214 penetrates the fixed cover 201, and the second clamping block 214 is slidably connected to the fixed cover 201. An electric telescopic rod 215 is fixedly connected to the bottom inner end of the second clamping block 214, and the bottom end of the electric telescopic rod 215 is fixedly connected to the fixed cover 201. When a tripping phenomenon occurs during the use of the device, the occurrence of the tripping fault can be determined in time, and it can be automatically reset remotely after maintenance, thereby realizing remote intelligent control of the device and ensuring the safety of the operator. Moreover, when the remote intelligent control mechanism is installed and disassembled, the automatic operation is very convenient.

[0031] Working process: when installing the intelligent control mechanism, when the fixed cover 201 is limited at the left end of the outer side of the miniature circuit breaker 1 by the limit block 210, the electric telescopic rod 215 is extended by the controller 203. At this time, the second card block 214 will be inserted upward into the limit block 210 at the bottom, thereby completing the automatic connection when the intelligent control mechanism is installed. When the intelligent control mechanism needs to be removed, it only needs to control the electric telescopic rod 215 to retract and remove it to the left. The operation is simple and convenient.
