As shown in fig. 1-5, an outdoor intelligent switch with multiple sequential conduction of isolating switches comprises a switch shell, a solid-sealed pole 1, an isolating switch operating mechanism 2 and a spring operating mechanism 3, wherein the isolating switch operating mechanism 2 and the spring operating mechanism 3 are arranged in the switch shell, and a conductive loop of a driving device is switched on and conducted;
the solid-sealed pole 1 comprises a pole shell 11, three cavities and a connecting busbar 15 are respectively arranged in the pole shell 11, an isolating switch unit 12, an electric sensor unit 17 and a circuit breaker unit 13 are respectively arranged in the three cavities, and the isolating switch unit 12 drives up and down movement to implement closing and opening actions through an isolating switch operating mechanism 2; the breaker unit 13 is connected with the spring operating mechanism 3 through a breaker insulation pull rod 131 to implement closing and opening actions; the connection busbar 15 is connected to the disconnector unit 12 and the circuit breaker unit 13, respectively.
An insulating transparent observation window 111 is provided on the outer side of the pole housing 11 near the upper portion of the isolating switch unit 12, so as to observe the connection state of the isolating switch unit 12 through the insulating transparent observation window 111.
The isolating switch unit 12 comprises an isolating contact arm assembly, an upper isolating sleeve 14 and a lower isolating contact sleeve 16, the upper isolating sleeve 14 is arranged at the upper part of the pole shell 11, the lower isolating contact sleeve 16 is arranged at the middle part of the pole shell 11, and the upper isolating sleeve 14 is communicated with the connecting busbar 15; the purpose of the present invention is to provide the upper isolation sleeve 14 and the lower isolation contact sleeve 16 to enable the isolation switch unit 12 to gradually abut against the upper isolation sleeve 14 in stages, so that an operator can fully understand whether the isolation switch unit 12 abuts against the upper isolation sleeve 14 to form a current switch-on in terms of operation behavior and sensory feel, and can observe the abutting state of the isolation switch unit 12 against the upper isolation sleeve 14 through the insulating transparent observation window 111, and when the upper end of the isolation switch unit 12 abuts against the upper isolation sleeve 14, the middle part of the isolation switch unit 12 abuts against the lower isolation contact sleeve 16 to form a current communication.
The middle part of the inner side of the upper isolation sleeve 14 is provided with a protruding connecting piece, the isolation contact arm assembly comprises an isolation contact arm body 121 and an isolation switch insulation pull rod 122, the isolation contact arm body 121 is connected with the isolation switch operating mechanism 2 through the isolation switch insulation pull rod 122, the isolation contact arm body 121 is connected with the isolation switch insulation pull rod 122 through a pivot hinge, a second spring contact finger 124 and a first spring contact finger 123 are respectively arranged on the upper part and the lower part of the outer side of the isolation contact arm body 121, and a third spring contact finger 125 is also arranged at the corresponding part of the upper part of the inner side of the isolation contact arm body 121 and the second spring contact finger 124; the purpose of this arrangement is to form a three-point connection with the first spring contact finger 123, the second spring contact finger 124, and the third spring contact finger 125, since the three spring contact fingers are all spring-loaded and the springs have a certain deformability, when the isolation contact arm body 121 is placed in the pole housing 11, the isolation contact arm body 121 can form an interference fit inside the pole housing 11 through the first spring contact finger 123 and the second spring contact finger 124, and when in current communication, the pole housing 11 is electrically conductive, so that the first spring contact finger 123 is in contact with the inner wall of the pole housing 11 whenever the isolation contact arm body 121 slides into the pole housing 11, and when the isolation contact arm body 121 moves up, the third spring contact finger 125 is in preference to the second spring contact finger 124 being in contact with the raised connection of the upper isolation sleeve 14, and then allowing the second spring contact finger 124 to be in current communication until the upper end of the isolation contact arm body 121 is fixed against the surface of the upper isolation sleeve 14. Based on this, when the current needs to be switched off, the isolating switch unit 12 can be adjusted to move down and separate the second spring contact finger 124 and the third spring contact finger 125 from the state of being propped against the upper isolating sleeve 14, and when the current is switched on, the isolating switch unit 12 is lifted and the second spring contact finger 124 and the third spring contact finger 125 respectively prop against the inner side of the upper isolating sleeve 14 and the outer side of the protruding connecting piece. The specific current switching-on and switching-off structure can be referred to figures 4 and 5;
