[0002] A pole-mounted isolating switch is an electrical device installed on a pole or concrete pier, and is mainly used to isolate the line in the distribution network. It does not carry load current, but is only used to separate the live part from the dead part to ensure the personal safety of maintenance personnel when inspecting, repairing or replacing other equipment. The main features of the pole-mounted isolating switch include: simple structure: compared with circuit breakers or load switches, the pole-mounted isolating switch has a simpler structure and usually does not have complex operating mechanisms and protective devices; easy installation and maintenance: due to its simple structure, installation and maintenance are relatively convenient and quick; outdoor use: designed for outdoor use, with good waterproof, dustproof and corrosion resistance, and can work stably in harsh natural environments; manual operation: most pole-mounted isolating switches are manually operated, which is convenient for on-site operators to directly control;

The top ends of the two groups of vertical frame bodies 74 are vertically connected to the horizontal frame body 73, and the top surface of the horizontal frame body 73 is vertically symmetrically provided with a vertical tooth plate 731, which is engaged with the inner side of the swing gear 721. One end of the spring rod 75 is connected to the vertical frame body 74, and the other end is connected to the inner wall of the detection box 3.

[0082] In the above scheme:

[0083] 1. The water in the water tank is sprayed out to the switch on the column through the swing pipe and the spray pipe;

[0086] In the third state, the second driving rod 95 drives the pushing assembly 94 and the abutting inclined block 93 to move back and forth, the pushing assembly 94 drives the moving column 222 to move back and forth horizontally, the abutting inclined block 93 abuts against the matching inclined block 741 back and forth, causing the vertical tooth plate 731 to rise and fall, thereby driving the spray pipe 71 to swing back and forth to spray water.

[0087] In the above scheme: the second driving rod can drive the pushing component to move back and forth, the pushing component drives the movable sleeve to move along the central axis rod, and the pushing component can push the movable column to move back and forth to realize the reciprocating opening and closing test of the switch on the column. At the same time, the movable sleeve will also drive the resistance inclined block to move, and the resistance inclined block reciprocates and resists the matching inclined block to realize synchronous swinging spraying, without the need to set up a separate swinging driving structure.
