Description

Technical Field

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

[0002] Pole-mounted circuit breakers refer to circuit breakers installed and operated on electric poles. With the rapid development of my country's economy and the continuous increase in power supply, especially the increasing dependence of various customers on electricity, in order to improve the power supply reliability of the power grid, pole-mounted circuit breakers are often used in the connection, segmentation and branch lines of the power grid to improve the power supply reliability of the power grid. Therefore, how to install pole-mounted circuit breakers on electric poles more reliably and adapt to the needs of various customers has become a very important issue.

[0003] In the related art, the pole-mounted circuit breaker is fixed on the pole by welding a simple bracket into a profile steel structure. Such a bracket has poor flexibility and cannot meet customer needs. The fixed installation position of such a bracket is usually at a certain height from the ground. When the bracket is fixedly installed, the installation position of the pole-mounted circuit breaker is also fixed and cannot be moved. In case the height of the bracket fixing position is not suitable, the position of the bracket needs to be adjusted again in a high-altitude environment, which is cumbersome to operate and increases the risk factor. For this reason, we design a fixing device for the pole-mounted circuit breaker to solve the above technical problems. Utility Model Content

[0010] As a further preferred solution of the utility model: the fastening bolt is located directly above the vertical sliding groove adjacent to it.

[0011] Compared with the prior art, the beneficial effect of the utility model is that when the device is used, the two installation frames are fixedly installed through the cooperation connection of multiple mounting bolts and fastening nuts, as well as the action of two upper clamping arc plates and two lower clamping arc plates. Then, according to actual installation requirements, the height of the fixing plate can be adjusted.

When it moves to a suitable position, the fastening bolts are screwed, and the multiple fastening bolts are connected and cooperated with the respective corresponding screw holes to fix the position of the fixing plate at this time, and then the circuit breaker and related equipment are installed on the fixing plate. Therefore, the height of the device can be adjusted again after it is fixed at the initial height position, which greatly reduces the danger of high-altitude operations. In addition, through the cooperation of the indicator block and the scale line, it is convenient to know the specific adjusted height of the circuit breaker and related equipment.
