Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a production and detection device for a pole-mounted circuit breaker. Background Art

[0002] In the power system, pole-mounted circuit breakers are key equipment to ensure the safe and stable operation of the distribution network. Their quality and performance are directly related to the reliability of power supply. In the production process of pole-mounted circuit breakers, it is very important to conduct comprehensive and accurate testing on them.

[0003] The existing production and testing of pole-mounted circuit breakers faces many challenges. On the one hand, the pole-mounted circuit breaker needs to be operated through the energy storage handle and the closing handle during actual operation, but it is difficult to simulate these operations in the production and testing process. Since different operators have different control over the operating force and frequency, it is difficult to ensure the consistency of operation, which greatly affects the accuracy and reliability of the test results. For example, when detecting the mechanical structure response of the circuit breaker, differences in human operation may lead to misjudgments on whether the circuit breaker is stuck or refuses to move.

[0004] On the other hand, pole-mounted circuit breakers come in a variety of models, and the positions and sizes of the energy storage handles and closing handles of each model are different. This makes it difficult for the detection device to adapt to pole-mounted circuit breakers of different models and installation locations, limiting its versatility and applicability, and making it impossible to carry out detection work efficiently.

[0005] In view of this, there is an urgent need for a pole-mounted circuit breaker production and testing device to solve the above-mentioned technical problems such as operation simulation, position adaptation, and detection accuracy, and to improve the quality and efficiency of pole-mounted circuit breaker production and testing. Utility Model Content

[0028] Furthermore, the clamping block is rotatably arranged on the rod body.

[0029] Furthermore, a release groove is provided on the outer periphery of the column, and the release groove is communicated with the ball groove.

[0030] Beneficial effects of the utility model:

[0031] (1) The base is provided with a slot, in which the card strip of the drive assembly can be slidably disposed, and connected to the fixing seat by bolts, so that the position of the drive assembly can be adjusted on the base. This makes it convenient for the operator to flexibly adjust the position of the drive assembly according to the different positions of the energy storage handle and closing handle of the pole-mounted circuit breaker, so as to accurately operate the corresponding handle, thereby improving the adaptability of the detection device to pole-mounted circuit breakers of different specifications or installation methods.

[0046] The utility model is further described in detail below with reference to the accompanying drawings.

[0047] A pole-mounted circuit breaker production and detection device comprises a base 1, a pole-mounted circuit breaker 3 is fixedly arranged on the upper end of the base 1 by bolts, and a plurality of connection holes are arranged on the upper end of the base 1 to connect pole-mounted circuit breakers 3 of different sizes. The pole-mounted circuit breaker 3 is provided with a pullable energy storage handle 301 and a closing handle 302.

[0048] In actual operation, when the pole-mounted circuit breaker 3 needs to be closed, the energy storage handle 301 needs to be pulled several times until the pointer reaches the energy storage state. Then the closing handle 302 is pulled down, and the pointer points to "closed" to indicate that the circuit has been closed.

[0049] In order to realize the above operations, a plurality of position-adjustable driving components 2 are provided on the base 1 , and the energy storage handle 301 and the closing handle 302 are pulled down by the driving components 2 .

[0050] The outer periphery of the base 1 is provided with a horizontal slot 101, which is a T-slot. The driving assembly 2 includes a fixed seat 202, on which a cylinder 201 is fixedly arranged, and a telescopic rod of the cylinder 201 is vertically upward. A clip 203 is slidably embedded in the slot 101, and the clip 203 is connected to the fixed seat 202 by bolts. Tightening the bolts can fix the position of the clip 203 and the fixed seat 202 on the base 1.

[0051] This can facilitate the operator to flexibly adjust the position of the drive assembly 2 according to the different positions of the energy storage handle 301 and the closing handle 302 of the pole-mounted circuit breaker 3, so as to accurately operate the corresponding handle, thereby improving the adaptability of the detection device to pole-mounted circuit breakers 3 of different specifications or installation methods.

[0052] The driving assembly 2 includes a connecting column 204, which is arranged at the telescopic end of the cylinder 201. The connecting column 204 is threadedly connected to the telescopic end of the cylinder 201. In order to facilitate the twisting of the connecting column 204, the outer periphery of the connecting column 204 adopts a regular hexagonal prism shape. The connecting rod 205 is swingably arranged on the connecting column 204; the clamping block 206 is rotatably arranged on the connecting rod 205. A detachable bayonet 207 is arranged on the clamping block 206. The pull ring of the energy storage handle 301 and the closing handle 302 is located between the clamping block 206 and the bayonet 207. Thereby, the cylinder 201 can pull the energy storage handle 301 and the closing handle 302. In addition, the connecting column 204 is threadedly connected to the telescopic end of the cylinder 201, the connecting rod 205 is swingably arranged on the connecting column 204, and the block 206 is rotatably arranged on the connecting rod 205, so that the position and angle of the block 206 can be adjusted, thereby matching the energy storage handle 301 and the closing handle 302 or other operating components at different positions and angles.

[0053] This design allows the operator to control the movement of the connecting column 204 through the cylinder 201, thereby driving the connecting rod 205 and the block 206 to move, and can more flexibly realize operations such as pulling down the energy storage handle 301 and the closing handle 302, making the operation process more convenient and efficient.

[0054] In order to realize that the connecting rod 205 can be swingably arranged on the connecting column 204, a ball connection is adopted between the connecting rod 205 and the connecting column 204. In a specific implementation, the connecting column 204 includes a column 2041, and the column 2041 is arranged at the telescopic end of the cylinder 201. The rear end of the column 2041 is provided with a threaded hole, and the threaded hole is threadedly connected with the telescopic end of the cylinder 201. The ball groove 2042 is provided at the front end of the column 2041. The connecting rod 205 includes a ball head 2051, and the ball head 2051 is movably embedded in the ball groove 2042. The rod body 2052 is arranged on the ball head 2051, and the rod body 2052 can swing relative to the column 2041. The block 206 is rotatably arranged on the rod body 2052.

[0055] The outer circumference of the column 2041 is provided with six release grooves 2043 . The release grooves 2043 are located at the upper end of the column 2041 . The release grooves 2043 are communicated with the ball grooves 2042 .

[0056] When the pulling force of the cylinder 201 is too large, the ball head 2051 can cause the ball groove 2042 to deform outward, and the release groove 2043 can cause the ball head 2051 to escape from the ball groove 2042, thereby preventing the energy storage handle 301 and the closing handle 302 from being damaged due to the overload of pulling force.

[0057] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
