Description

Technical Field

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

[0002] A pole-mounted circuit breaker is a circuit breaker installed and operated on an electric pole. A circuit breaker is a switching device that can close, carry and disconnect currents under normal circuit conditions, and can close, carry and disconnect currents under abnormal circuit conditions (including short-circuit conditions) within a specified time. Usually, the circuit breaker terminals and outgoing terminals are made of copper metal sheets, which are directly connected to overhead lines and cables, and then the surface is covered with an insulating sleeve for insulation protection to prevent rainwater from dripping in.

[0003] The existing metal sheets are directly connected to the overhead lines and cables, which are in an overhead state and are prone to swinging and becoming unstable due to external factors, thereby reducing the reliability of the equipment. For example, the utility model patent with the authorization announcement number CN219626569U discloses an insulating connection device for a pole-mounted circuit breaker. As a prior art, although the device realizes the clamping and fixing of cables of different sizes to prevent the cables from being unstable due to swinging, it still has certain use defects. The device clamps the cables by moving the movable clamp block and keeping the fixed clamp block stationary. Therefore, when the cables are of different sizes, although they can be clamped and fixed, there will be some deviation in the position after clamping and fixing, that is, the clamping effect is not to clamp the cables in the center, and the upper arc plate is connected with the lower arc plate, and there is no seal between the upper arc plate and the outer surface of the insulating mounting cover, and there is even a gap. Rainwater may flow into the through hole on rainy days and damage the internal equipment. For this reason, we design an insulating connection device for a pole-mounted circuit breaker to solve the above technical problems. Utility Model Content

[0004] The utility model aims to provide an insulation connection device for a pole-mounted circuit breaker to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] As a further preferred solution of the utility model: the driven pulley A and the driving pulley A are connected via a first synchronous belt transmission, and the driven pulley B and the driving pulley B are connected via a second synchronous belt transmission.

[0011] As a further preferred solution of the utility model: the first lifting block, the second lifting block and the third lifting block located on the same side of the through hole are all located at the same horizontal height.

[0012] As a further preferred solution of the utility model: the knob is connected to the driving pulley A via a rotating shaft, and the outer surface of the knob is provided with anti-slip grooves.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: when the device is used, the anti-slip pattern is provided to facilitate the staff to turn the knob, and then drive the active pulley A to rotate through the rotating shaft, and then drive the first rotating rod to rotate together with the first threaded rod. At the same time, the driven pulley A and the driven pulley B can be driven to rotate through the first synchronous belt and the second synchronous belt, and then the second threaded rod and the third threaded rod can be driven to rotate, so the lifting blocks located on the upper and lower sides can be driven to approach or move away from each other, that is, the clamping arc plates on the upper and lower sides of the control through hole can be driven to approach each other, and cables of different sizes can be clamped and fixed, thereby ensuring the stability when the cable is installed and connected, preventing the cable from being loosely connected due to swinging, and thus improving the reliability of the equipment.
