Technical Field
[0001] The present invention relates to the technical field of circuit breakers, and more particularly to a primary-secondary fusion pole-mounted circuit breaker. Background Art
[0002] The primary and secondary integrated pole-mounted circuit breaker is a highly integrated power equipment. It deeply integrates the traditional primary equipment (mainly performing functions such as power transmission and circuit separation and combination) and the secondary equipment (used for measurement, protection, control, communication, etc.). In one equipment unit, it contains both the circuit breaker body (primary equipment part) and the secondary equipment parts such as intelligent control, measurement, protection and communication, realizing the intelligent management and protection of distribution lines.
[0003] As the key connection part for the conversion of the circuit state of the primary and secondary fusion column-mounted circuit breaker, the isolating knife switch is mainly composed of moving contacts, static contacts, insulators, operating mechanisms and other parts. From the appearance, the isolating knife usually has a structure similar to a knife switch. The moving contact can be opened and closed with the static contact under the drive of the operating mechanism. The insulator is used to support the conductive part of the isolating knife to ensure its insulation with other parts.
[0004] The modernization of power grids in Northwest my country is being promoted. The integrated primary and secondary pole-mounted circuit breakers can realize intelligent monitoring and control of power grids. They can collect power grid operation data in real time, such as voltage, current, power and other parameters, and transmit these data to the control center to realize remote monitoring and fault diagnosis, which is crucial to improving the intelligence level of power grids in Northwest China.
[0005] There are large deserts such as the Taklimakan Desert and the Gurbantunggut Desert in the northwest of my country. These deserts provide abundant sources of sand and dust, which are easily blown up and transported to surrounding areas, causing dust to easily accumulate on the isolating switches of the primary and secondary fusion pole-mounted circuit breakers in the surrounding areas. The dust may contain conductive substances, which will form a weak conductive channel after accumulating on the surface of the isolating switches. In a high-voltage environment, it is easy to reduce the resistance of the insulating part of the isolating switches, which reduces the insulation strength of the isolating switches between phases or to the ground, increases the risk of electrical breakdown, and may cause short-circuit faults. In addition, after the dust covers the isolating switches, the heat generated by the current flowing through the isolating switches is easy to accumulate and difficult to dissipate, causing the temperature of the isolating switches to rise, which may affect the use of the isolating switches and shorten the service life of the isolating switches. In view of this, we propose a primary and secondary fusion pole-mounted circuit breaker. Summary of the invention

[0017] A method for using a primary-secondary fusion pole-mounted circuit breaker, comprising the following steps:
[0018] S1. During the wind direction adjustment process, the isolation knife gate is brushed and dusted. There are many strong winds in the northwest region. When strong winds blow, the wind vane of the wind vane is blown by the wind force, so that the wind vane rotates until it is consistent with the wind direction. During the rotation of the wind vane, the wind vane and the wind block are driven to rotate. At the same time, the conical column of the wind vane drives the wind hood and the circular ring plate to rotate around the circular sliding channel of the side wall of the bellows. During the rotation of the circular ring plate, the tooth groove on its bottom surface drives the meshing gear 1 to rotate, and the gear 1 drives the coaxially connected gear 2 to rotate. The gear 2 drives the gear 3 to rotate through the toothed belt, and further drives the coaxially connected gear 4 to rotate. The gear 5, gear 6, gear 7 and gear 8 are driven to rotate by the gear 4. The gear 6 and gear 8 drive the rotating frame to rotate. During the rotation of the rotating frame, the flexible brush on its side wall brushes and dusts the outer wall of the isolation knife gate, effectively removing the dust accumulated on the side wall of the isolation knife gate;
[0019] S2. After the wind direction adjustment is completed, the isolation knife gate is subjected to centralized dust blowing operation. When the wind vane's wind direction plate rotates to be consistent with the wind force and direction, it stops moving, and the flexible brush of the rotating frame stops brushing and cleaning the outer wall of the isolation knife gate. At this time, the air guide channel of the induced draft hood and the air block will be connected to the air inlet channel of the side wall of the ventilation box. The induced draft hood faces the direction of the wind force, and the wind force is blown into the air inlet channel of the side wall of the wind box through the induced draft hood. The wind flows from the larger channel to the smaller channel, which will increase the flow rate, so that the wind force quickly flows from the air inlet channel into the air guide channel, and flows to the inner cavity of the three ventilation ducts at the bottom through the air guide channel, and finally blows out from the air outlets of the three air outlet ducts. The wind force is concentratedly blown to the outer surface of the isolation knife gate, effectively blowing away the dust on the surface of the isolation knife gate;
[0020] S3. The dust blowing operation and the brushing and dust cleaning operation are performed alternately. When the direction of the wind changes, the wind vane will readjust the angle according to the wind direction and rotate, thereby driving the rotating frame to rotate again, so that the flexible brush on its side wall will brush and dust the outer wall of the isolation knife gate. After the wind vane completes the wind direction alignment operation, the wind is re-directed into the air inlet channel and the air guide channel through the air induced draft hood, and finally blown out from the air outlets of the three air outlet ducts to blow away the dust on the surface of the isolation knife gate. By alternating the dust blowing operation and the brushing and dust cleaning operation according to the change of wind direction, the dust on the outer surface of the isolation knife gate is effectively cleaned.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] 1. The present invention is designed with wind collecting components and pollution cleaning components suitable for the windy climate of the northwest region, and can use natural wind power to complete the dust blowing operation and brushing and dust cleaning operation of the isolation knife switch, and can perform alternating brushing and dust blowing operations according to the change of wind direction, so as to avoid the accumulation of a large amount of dust on the outer surface of the isolation knife switch, and ensure that the outer surface of the isolation knife switch can always be kept in a relatively clean state during long-term use, thereby solving the problem that the isolation knife switch of the primary and secondary fusion column circuit breaker in the northwest region is prone to dust accumulation, and when the dust covers the isolation knife switch, the device is prone to short-circuit faults and affects the use effect of the isolation knife switch.
[0023] 2. The present invention designs a wind direction adjusting component and a wind receiving component so that no matter which direction the wind blows from, the wind vane of the wind direction adjusting component can be rotated and adjusted to align the wind direction, and then the wind is received by the bellows of the wind receiving component to utilize the wind, which has strong flexibility and practicality.
[0024] 3. In the present invention, when the wind blows the weather vane, the wind vane rotates until it is consistent with the wind direction. During the rotation of the wind vane, the wind vane and the wind block are driven to rotate. At the same time, the conical column of the wind vane drives the wind hood and the circular ring plate to rotate around the circular sliding channel of the side wall of the wind box. During the rotation of the circular ring plate, the tooth groove on the bottom surface drives the meshing gear 1 to rotate, the gear 1 drives the coaxially connected gear 2 to rotate, the gear 2 drives the gear 3 to rotate through the toothed belt, and further drives the coaxially connected gear 4 to rotate, and the gear 5, gear 6, and gear 7 are driven by the gear 4. Wheel seven and gear eight rotate, and gear six and gear eight drive the rotating frame to rotate. During the rotation of the rotating frame, the flexible brush on the side wall brushes and cleans the outer wall of the isolation knife gate, effectively removing the dust accumulated on the side wall of the isolation knife gate, ensuring that when the wind direction changes, the wind direction plate rotates, the rotating frame can drive the flexible brush to rotate and brush and clean the outer wall of the isolation knife gate, so that the dust accumulated on the outer surface of the isolation knife gate can be removed in large quantities, and the dust remaining on the outer surface of the isolation knife gate becomes loose, thereby improving the cleaning effect of the subsequent dust blowing operation.
[0025] 4. The present invention also drives the induced draft hood and the circular ring plate to rotate around the circular sliding channel of the side wall of the wind box through the conical column of the wind vane. The induced draft hood and the wind block's air guide channel are connected to the air inlet channel of the side wall of the wind box. The induced draft hood faces the direction of the wind force, and the wind force blows into the air inlet channel of the side wall of the wind box through the induced draft hood. By designing the inner cavity of the induced draft hood to be a large outer and small inner structure, the aperture of the air inlet channel is designed to decrease from the outside to the inside, so that the wind is blown into the air inlet channel through the induced draft hood when the air volume remains unchanged. It will flow from the larger channel to the smaller channel, increasing the wind flow rate. When the wind speed becomes faster, the dust blowing effect can be improved, and it will flow through the air guide channel to the inner cavity of the three-air duct at the bottom, and finally blown out from the air outlets of the three air outlet ducts. The wind force is concentrated to blow to the outer surface of the isolation knife switch, effectively blowing away the dust on the surface of the isolation knife switch, and using the induced draft hood to increase the amount of wind received, further increase the air volume circulating in the air inlet channel, increase the air volume and wind speed at the air outlet of the air outlet duct, and improve the cleaning effect of dust blowing.
[0026] 5. The present invention also arranges air blocks at the output ends of multiple air inlet channels. When the air guide channel of the air block is connected to the air inlet channel, the circumferential outer wall of the air block will block the output ends of the remaining air inlet channels to prevent wind from flowing between the multiple air inlet channels, thereby reducing the air volume entering the three air outlet pipes, ensuring the stability of the air volume in the air outlet pipes, and further improving the dust blowing effect.

[0055] S1. Wind direction adjustment process: The isolation knife gate 104 is brushed and dusted. There are many strong winds in the northwest region. When strong winds blow, the wind vane 22043 of the wind vane 2204 is blown by the wind force, so that the wind vane 22043 rotates until it is consistent with the wind direction. During the rotation of the wind vane 22043, the wind vane 2204 and the wind block 2201 are driven to rotate. At the same time, the conical column 22041 of the wind vane 2204 drives the air hood 2209 and the circular plate 2212 to rotate around the circular sliding channel of the side wall of the wind box 2104. During the rotation of the circular plate 2212, the tooth grooves 22121 on the bottom surface thereof are The meshing gear 1 302 is driven to rotate, the gear 1 302 drives the coaxially connected gear 2 303 to rotate, the gear 2 303 drives the coaxially connected gear 304 to rotate through the toothed belt 305, and further drives the coaxially connected gear 4 306 to rotate, and the gear 4 306 drives the gear 5 307, the gear 6 308, the gear 7 309 and the gear 8 310 to rotate, the gear 6 308 and the gear 8 310 drive the rotating frame 313 to rotate, and during the rotation of the rotating frame 313, the flexible brush 316 on the side wall thereof brushes and cleans the outer wall of the isolation knife gate 104, and effectively removes the dust accumulated on the side wall of the isolation knife gate 104;
[0056] S2. After the wind direction adjustment is completed, the isolation knife gate 104 is subjected to centralized dust blowing operation. When the wind vane 2204 wind direction plate 22043 rotates to be consistent with the wind direction, it stops moving, and the flexible brush 316 of the rotating frame 313 stops brushing and cleaning the outer wall of the isolation knife gate 104. At this time, the air hood 2209 and the air guide channel 22011 of the air block 2201 are connected to the air inlet channel 21041 of the side wall of the ventilation box 2104. The air hood 2209 is facing the direction of the wind, and the wind passage 22011 of the air block 2201 is connected to the air inlet channel 21041 of the side wall of the ventilation box 2104. The air hood 2209 is facing the direction of the wind. The wind is blown into the air inlet channel 21041 on the side wall of the wind box 2104 through the induced draft hood 2209. The wind flows from the larger channel to the smaller channel, which increases the flow rate, so that the wind force quickly flows from the air inlet channel 21041 into the air guide channel 22011, and flows to the inner cavity of the three ventilation pipes 2206 at the bottom through the air guide channel 22011, and finally blows out from the air outlets of the three air outlet pipes 2207. The wind force is concentrated and blown to the outer surface of the isolation knife gate 104, effectively blowing away the dust on the outer surface of the isolation knife gate 104;
[0057] S3. The dust blowing operation and the brushing and dust cleaning operation are performed alternately. When the direction of the wind changes, the wind vane 2204 will readjust the angle according to the wind direction and rotate, thereby driving the rotating frame 313 to rotate again, so that the flexible brush 316 on its side wall performs a brushing and dust cleaning operation on the outer wall of the isolation knife gate 104. After the wind vane 2204 completes the wind direction alignment operation, the wind is re-directed into the air inlet channel 21041 and the air guide channel 22011 through the air duct 2209, and finally blown out from the air outlets of the three air outlet pipes 2207 to blow away the dust on the surface of the isolation knife gate 104. By alternating the dust blowing operation and the brushing and dust cleaning operation according to the change of wind direction, the dust on the outer surface of the isolation knife gate 104 is effectively cleaned.
