Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of circuit breakers, in particular to a primary and secondary fusion integrated complete set of pole-mounted circuit breaker convenient to install. BACKGROUND

[0002] The primary and secondary fusion integrated pole-mounted circuit breaker refers to the fusion of primary equipment (such as the circuit breaker body) and secondary equipment (such as measurement, control, protection, etc.), forming a set of standardized installation on the pole circuit breaker equipment. The pole-mounted circuit breaker is essentially a high-voltage switch installed on a power pole for outdoor distribution lines with arc extinguishing devices, which can quickly cut off the current and extinguish the arc when the circuit fails, ensuring the safety of the line. The bottom end of the primary and secondary fusion integrated complete set of pole-mounted circuit breaker is usually provided with a support plate, which can be conveniently fixed on the power pole with bolts.

[0003] By integrating advanced power electronic component manufacturing technology, modern pole-mounted circuit breakers achieve precise current detection and intelligent tripping control, greatly improving the level of power distribution automation. To ensure the normal use of the pole-mounted circuit breaker, the staff will regularly climb the pole to maintain it. The pole-mounted circuit breaker usually has an operating handle and an energy storage handle. During maintenance of the pole-mounted circuit breaker, the operating handle is usually used to place it in the tripping state. If the pole-mounted circuit breaker is under maintenance, accidental contact with the operating handle will cause it to close, and the pole-mounted circuit breaker will instantly connect the high-voltage line, causing the worker who is touching the live part to be directly electrocuted, endangering life. If the operating mechanism is in the uncharged state during maintenance, accidental contact with the energy storage handle will cause the operating mechanism to complete the charging. At this time, if the locking device of the operating mechanism fails and the worker accidentally touches the operating handle, the energy storage release may directly drive the circuit breaker to close or open, causing the same risk of electric shock and short circuit as accidental contact with the operating handle.

[0026] Working principle: firstly, the mounting base 7 is fixed on one side of the mechanism box 1 and above the two transmission shafts 2, before the maintenance of the pole-mounted circuit breaker integrated with the precise power electronic component manufacturing technology, the pole-mounted circuit breaker is in the open state by means of the operation handle 3, and it is also necessary to ensure that the pole-mounted circuit breaker is in the non-energy storage state, before the maintenance of the pole-mounted circuit breaker, the operation handle 3 and the energy storage handle 4 are respectively limited, so as to avoid the situation that the operation handle 3 and the energy storage handle 4 are mistakenly touched during the maintenance; The default state of the operation handle 3 when not in use is horizontally arranged, when the operation handle 3 is limited, the limit rod one 9 is rotated towards the operation handle 3, under the action of the transmission rod 10 on one side of the limit rod one 9, the receiving plate 11 slides along the two guide rods one 12 and presses the two springs one 13, under the action of the receiving plate 11, the other limit rod one 9 and the transmission rod 10 synchronously act, the two limit rods one 9 are simultaneously rotated and approach each other, with the rotation of the limit rod one 9, the two rotary shafts one 8 are synchronously rotated and drive the corresponding clamping grooves one 14 to synchronously rotate, when the two limit rods one 9 are rotated to the limit position, the two limit rods one 9 at this time are in contact with the operation handle 3, the operation handle 3 is limited, at the same time, the four clamping grooves one 14 are respectively matched with the ends of the two clamping plates one 15, under the action of the multiple springs two 17, the ends of the two clamping plates one 15 are respectively inserted into the corresponding clamping grooves one 14, so as to fix the position of the two rotary shafts one 8; under the action of the first limiting mechanism, the position of the operation handle 3 is limited, so as to avoid that the operation handle 3 is mistakenly touched by the staff during the maintenance of the pole-mounted circuit breaker, which makes the pole-mounted circuit breaker close and endangers the life of the staff; The default state of the energy storage handle 4 is inclined when not in use. When the energy storage handle 4 is limited, the limiting rod three 20 is first rotated, the limiting rod three 20 drives the rotating shaft two 18 to rotate synchronously, the spring three 21 at the bottom of the limiting rod three 20 is stretched under force, the clamping grooves two 22 at both ends of the rotating shaft two 18 rotate synchronously, when the two clamping grooves two 22 correspond to the two clamping plates two 23, the two clamping plates two 23 move towards the rotating shaft two 18 under the elastic force of the corresponding spring four 25, one end of the two clamping plates two 23 is inserted into the corresponding clamping groove two 22, the limiting rod three 20 is fixed, and under the action of the limiting rod two 19, the energy storage handle 4 is limited. During the process of limiting the energy storage handle 4 by the limiting rod three 20, the connecting rod 29 rotates synchronously with the limiting rod three 20, the limiting shaft 30 at the end of the connecting rod 29 away from the limiting rod three 20 acts on the connecting groove 28 at the bottom, the connecting block 26 pulls the limiting rod two 19 to move downwards synchronously, the spring five 27 at the top of the connecting block 26 is stretched under force, the limiting rod two 19 is close to the limiting rod three 20, and the energy storage handle 4 is fixed in position. Under the action of the auxiliary assembly, the limiting rod two 19 can move slightly in the vertical direction. When the energy storage handle 4 is rotated to store energy in the mechanism box 1, the energy storage handle 4 will touch the limiting rod two 19, at this time, the limiting rod two 19 drives the connecting block 26 to move synchronously, and the spring five 27 is pressed under force, so as to avoid the rigid contact between the energy storage handle 4 and the limiting rod two 19. After the maintenance work is completed, the threaded rod 32 is rotated, the adjusting plate 33 moves downwards under the action of the two guide rods four 34, and the four push plates 35 move downwards synchronously, the four push plates 35 act on the corresponding clamping plate one 15 and clamping plate two 23 respectively, so that the two clamping plate one 15 is separated from the corresponding clamping groove one 14, the two clamping plate two 23 is separated from the corresponding clamping groove two 22, and the two limiting rod one 9, limiting rod two 19 and limiting rod three 20 are reset.
