Description

Technical Field

[0001] This invention relates to the field of bypass uninterrupted power operation technology, specifically to a lifting and conveying device for a bypass switch. Background Technology

[0002] Actively carrying out uninterrupted bypass operations in distribution networks to achieve completely uninterrupted maintenance of distribution lines is a development goal of distribution network construction. The most important aspect of implementing bypass operations is the correct arrangement of bypass cables and equipment. When temporarily fixing bypass switches on poles, it is necessary to first adjust the metal chain of the bypass switch fixing hardware to a suitable length according to the pole diameter, wrap the chain around the pole, tighten the nut, and then lift the bypass switch to a safe height using a small hoist of an insulated bucket truck or manually before hanging it on the fixing hardware. The fixing must ensure that the bypass switch does not wobble or slip. This work is labor-intensive, time-consuming, and requires high installation skills, making it difficult for non-professionals to complete correctly. If the bypass switch is fixed on the bracket of the bypass switch truck or placed on the ground, it may cause unauthorized personnel to accidentally operate the switch or accidentally unplug the connector, leading to power outages or electric shock accidents, posing significant safety hazards. In addition, the height of the switch may not meet the requirements for operating the switch with an insulated operating rod, which also poses safety hazards to high-voltage equipment and workers.

The lower terminal of the normally closed point KA13-2 of intermediate relay 13 KA13 is connected to the negative terminal of power supply B.Its working principle is as follows: power supply B provides power to the entire system, switch QF controls the power supply of the entire system, A1 is the wireless receiver, SB is the emergency stop button of control system 4, SA1 is used to select between wired and wireless control modes, SA2 is the single-action wired control switch of the lifting system, SA3 is the single-action wired control switch of the horizontal sliding system 3, and SA4 is the wired linkage control switch, which can perform one-button operation on the entire bypass switch lifting device.

[0013] The specific control method of this invention is described in detail below: S1 Wired Control Mode: When the wired / wireless selection switch SA1 is in wired control mode, the lifting device will operate via the bypass switches SA2, SA3, and SA4.

[0014] In this invention, SA2 is a single-action wired control switch for the lifting system, which can jog to control the lifting mechanism's raising and lowering. When the normally open contact one of the lifting control switch SA2 is closed, the coil of intermediate relay 10 KA10 is energized, and the normally open contact two of intermediate relay 10 KA10 KA10-2 is closed, causing the motor M1 of the lifting push rod 21 to move in the forward direction, and the lifting mechanism 22 to rise. When the normally open contact two of the lifting control switch SA2 is closed, the coil of intermediate relay 11 KA11 is energized, and the normally open contact two of intermediate relay 11 KA11 KA11-2 is closed, causing the motor M1 of the lifting push rod 21 to move in the reverse direction, and the lifting mechanism 22 to fall.

[0015] SA3 is a single-action wired control switch for the horizontal sliding system 3, which can jog the extension and retraction of the upper platform 33. When the normally open contact one of the horizontal control switch SA3 is closed, the coil of intermediate relay twelve KA12 is energized, the normally open contact two of intermediate relay twelve KA12 KA12 KA12-2 is closed, the motor M2 of the horizontal push rod 31 moves in the forward direction, and the upper platform 33 slides outward; when the normally open contact two of the horizontal control switch SA3 is closed, the coil of intermediate relay thirteen KA13 is energized, the normally open contact two of intermediate relay thirteen KA13 KA13-2 is closed, the motor M2 of the horizontal push rod 31 moves in the reverse direction, and the upper platform 33 retracts.

[0016] SA4 is a wired linkage control switch. When the normally open contact of the one-button control switch SA4 is closed, the coils of intermediate relays KA3, KA5, and KA7 are energized. The normally open contacts KA3-1 and KA3-2 of intermediate relay KA3 are engaged, as are the normally open contacts KA5-1 and KA5-2 of intermediate relay KA5. This causes the motor M1 of the lifting push rod 21 to move forward, and the lifting mechanism 22 to rise. When it reaches the highest position, the normally open contact of position sensor 23 closes, energizing the coil of intermediate relay KA1 and engaging its normally open contact. At this time, the motor M2 of the horizontal push rod 31 is energized, pushing the upper platform 33 out until it automatically stops at the farthest point. At this point, the one-button control bypass lifting device has reached the working position. When the normally open contact 2 of the one-button control switch SA4 closes, the coils of intermediate relays KA4, KA6, and KA8 are energized. The normally open contacts KA4-1 and KA4-2 of intermediate relay KA4 and KA6-1 and KA6-2 of intermediate relay KA6 are engaged, causing the horizontal push rod 31 motor M2 to reverse, and the upper platform 33 to retract. When retracted to the fully retracted position, the normally open contact of position sensor 35 closes, the coil of intermediate relay KA2 is energized, and its normally open contact is engaged. At this time, the lifting push rod 21 motor M1 is energized, controlling the lifting mechanism to descend until it automatically stops at the lowest point. At this point, the one-button control bypass lifting device has reached the retraction position.

[0017] S2 Wireless Control Mode: When the wired / wireless selector switch SA1 is in wireless control mode, the corresponding command is sent through the wireless remote control, the wireless receiver A1 receives the command, and sends control commands through the output points O1-O6 of A1, replacing the wired control switches SA2, SA3 and SA4. The control principle is the same as the wired control method.
