Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to a high-altitude primary and secondary fusion pole-mounted circuit breaker. Background Art

[0002] The primary and secondary integrated pole-mounted circuit breaker integrates the functions of the primary equipment (equipment directly involved in the transmission of electric energy) and the secondary equipment (equipment used for monitoring, protection and control) in the power system into a single device; this design aims to improve the operational efficiency, reliability and intelligence level of the power system; the pole-mounted circuit breaker refers to the circuit breaker installed and operated on the utility pole. The current installation method is to fix the circuit breaker box on a simple tooling platform, but in actual use, it is mostly suspended in the air on the utility pole. It is inevitable that the utility pole is easily hit by external human forces, which will transmit the force to the fixed position of the pole-mounted circuit breaker at the top of the utility pole, causing a certain degree of damage to the pole-mounted circuit breaker.

[0003] After searching, a new type of primary and secondary fusion pole-mounted circuit breaker disclosed in the prior art (Announcement No.: CN111883381A) records that "the bottom of the connecting mechanism is fixedly connected to the top of the bracket mechanism; the bottom of the reset mechanism is fixedly connected to a position inside the connecting mechanism; the connecting mechanism includes a fixed support frame, a groove A, and a socket A. The top of the fixed support frame is provided with a groove A, and four sockets A are symmetrically provided on the left and right sides of the bottom end surface of the fixed support frame; the top of the reset mechanism is fixedly connected to a position inside the base plate mechanism; the base plate mechanism is slidably connected to a position above the inside of the connecting mechanism; the bottom of the circuit breaker device is fixedly connected to the top of the base plate mechanism." When the electric pole is hit by external force, the weight of the circuit breaker device as a whole will fall, and the fixed frame will slide downward, The spring in the reset mechanism is squeezed so that the force acting on the circuit breaker is buffered to a certain extent. Finally, the spring resets the circuit breaker at the upper end, so that the circuit breaker returns to its original shape, thereby preventing the circuit breaker fixed on the utility pole from being damaged by external force, which affects the normal service life of the equipment. However, there is a lack of corresponding guiding structure between the connecting mechanism and the base plate mechanism of the circuit breaker, so that when the circuit breaker is installed in a high-altitude area, the strong wind in the high-altitude area will blow the short-circuit device and the base plate mechanism to shake, thereby increasing the probability of deformation, damage or even breakage of the circuit breaker connection. At the same time, the reset mechanism of the circuit breaker is directly exposed to the external environment, which makes it easy for foreign objects to be stuck in the spring and connecting mechanism of the reset mechanism, thereby affecting the buffering effect of the short-circuit device and reducing the stability of the short-circuit device during use.
