Mounting mechanism and mounting method for pole-mounted circuit breaker

Abstract

The invention discloses a mounting mechanism and a mounting method for a pole-mounted circuit breaker. The mounting mechanism comprises a pole, a mounting bracket and an oblique support. The pole is fixedly provided with a reversing wheel above the mounting bracket. The end of the mounting bracket, away from the pole, is hinged with a pre-mounting frame. One end of the pre-mounting frame, away from the mounting bracket, is connected with a pulling cord. The pulling cord is winded on the reversing wheel and extends to the ground. The mounting bracket is provided with a mounting slot for accommodating the pre-mounting frame. When the pre-mounting frame is turned into the mounting slot, the lower surface of the pre-mounting frame is flushed with the upper surface of the mounting frame. The upper surface of the pre-mounting frame is detachably connected with a pulley device. The middle part of the pre-mounting frame is hollowed out. The pulley device includes a cable, and the cable passesthrough the pre-mounting frame from the middle part of the pre-mounting frame and is connected to the pulley device. A construction frame is further connected between the pole and the mounting frame under the mounting bracket, and the construction frame includes a crossbar extending horizontally from the pole to the end of the mounting bracket away from the pole. In a mounting process of the mounting mechanism, a circuit breaker is not easily impacted and damaged, and the installation position of the pole-mounted circuit breaker is convenient to adjust.

Description

technical field [0001] The invention relates to the technical field of electric power engineering installation, in particular to an installation mechanism and an installation method of a pole-mounted circuit breaker. Background technique [0002] The pole-mounted circuit breaker is an outdoor circuit breaker installed and used on the pole. With the advancement of the national grid reconstruction project, a large number of pole-mounted circuit breakers need to be installed. [0003] In the prior art, the Chinese patent document with the authorization announcement CN206205553U discloses a new type of circuit breaker mounting bracket on a pole, including a horizontal support bar, the support bar is fixed on the pole, and the pole is below the support bar A hoop is fixed, and a diagonal support is connected between the hoop and the support cross bar. [0004] At present, the circuit breaker on the pole is mainly fixed by the installation bracket similar to the above; figure 1 ...

AI Technical Summary

Problems solved by technology

[0005] The existing installation methods mainly have the following problems: 1. When the circuit breaker 4 on the pole is not installed later, there may be no fixed point suitable for the installation of the pulley block 6 on the pole 1, and the cross arm 7 needs to be installed separately for the pulley block 6. to install

2. When the mounting bracket 2 is located directly below the cross arm 7, the upward moving track of the pole-mounted circuit breaker 4 is blocked by the mounting bracket 2, and the cable 5 needs to be artificially moved to displace the pole-mounted circuit breaker 4 and the mounting bracket 2. Until the pole-mounted circuit breaker 4 is lifted above the installation bracket 2, and then readjust the installation position of the pole-mounted circuit breaker 4, the pole-mounted circuit breaker 4 is easy to shake during this process, and it is easy to cause collision damage

3. When the orthographic projection of the installation bracket 2 and the cross arm 7 is misaligned, although the process of lifting the circuit breaker 4 on the pole to the top of the installation bracket 2 will not be blocked by the installation bracket 2, the circuit breaker 4 on the pole is not located at this time. Right above the installation bracket 2, the pole-mounted circuit breaker 4 needs to be moved to the installation bracket 2 for fixing, the adjustment angle is large, and there is a problem of difficulty in adjustment
