[0015] A leakage detection method for high and low voltage complete electrical equipment, applied to the leakage detection device for the above-mentioned high and low voltage complete electrical equipment, comprises the following operating steps: S1: Install the working components of the high and low voltage complete electrical equipment body on the mounting seat through the mounting groove, and install the top of the coil on the outer wall of the working components; S2: When leakage occurs in the working components of the high and low voltage complete electrical equipment body, the coil will give magnetism to the iron core to form an electromagnet. At this time, the iron core will absorb the magnetic block, so that the iron core can absorb the bottom of the detection component. At this time, the detection component will rotate at the fixed frame. The top of the rotating detection component will contact and squeeze the connecting rod through the pulley, so that the connecting rod can drive the warning component to extend out of the inner cavity of the high and low voltage complete electrical equipment body. With the help of the warning tape on the side of the warning component, the staff can be warned of leakage. When the warning component extends out of the inner cavity of the high and low voltage complete electrical equipment body, the leakage detection work of the high and low voltage complete electrical equipment body is also completed; S3: When the warning component extends out of the inner cavity of the high and low voltage complete electrical equipment body, the spring will retract the positioning block into the inner cavity of the high and low voltage complete electrical equipment body through the slider. At this time, the positioning block will fit on one end of the warning component, so as to limit the warning component; S4: When the detection component rotates, its top will drive the mounting seat to move in the direction of the warning component, so that the insulating panel can be driven to separate from the outer wall of the high and low voltage complete electrical equipment body. At this time, the working components installed in the inner cavity of the mounting groove can be exposed to the outside. The staff can then perform maintenance on the working components and can also determine whether the high and low voltage complete electrical equipment body is powered off. When the mounting seat moves, its two sides will move on the outer wall of the guide column through the movable groove, and at the same time, it will drive the limit slider to move on the outer wall of the movable block; S5: In normal state, the rack is set on the right side of the insulating panel. When the leakage detection accuracy of the high and low voltage complete electrical equipment body needs to be improved, the leakage detector is installed on the rack, and the handle is moved left and right to drive the adjustment block to move left and right in the inner cavity of the adjustment slot. At this time, the adjustment block will drive the connecting frame and the leakage detector to move left and right through the gear. After moving to the corresponding working component, the handle is turned to drive the gear to rotate so that it meshes with the rack. At this time, the height of the leakage detector can be adjusted, and the leakage detector is powered on through an external cable. At this time, the leakage detector can detect the leakage of the working component at the corresponding position, thereby improving the detection accuracy; S6: When the leakage of the high and low voltage electrical equipment is resolved, remove the leakage detector and external cables. After the iron core loses its magnetism, pull the handle outward so that the positioning block can be separated from the outer wall of the warning component. At this time, the first fixing rod will shrink the warning component through the shrinking block, so that the warning component can be reset. The reset warning component can also assist the mounting base and the insulating panel to be reset, thereby completing the overall leakage detection work.

[0016] Beneficial Effects Compared with the prior art, the present invention provides a leakage detection device and method for high and low voltage complete electrical equipment, which has the following beneficial effects: 1. The leakage detection device and method of the high and low voltage complete electrical equipment, through the set coil and iron core, when the high and low voltage complete electrical equipment body has leakage, the iron core will be energized to generate a magnetic electromagnet, so that the detection component that drives the magnetic block can be adsorbed, and after the detection component moves, the connecting rod can be driven to move, so that the warning component can move to the outer wall of the high and low voltage complete electrical equipment body. This structure can not only complete the leakage detection of the high and low voltage complete electrical equipment body, but also can warn the staff in conjunction with the set warning tape.

[0017] 2. The leakage detection device and method of the high and low voltage complete electrical equipment, through the arranged positioning block, will be attached to the side of the warning component in normal state. When the warning component moves to the outside of the high and low voltage complete electrical equipment body, the arranged spring can retract the positioning block into the inner cavity of the high and low voltage complete electrical equipment body. At this time, the positioning block can be attached to the outer wall of the warning component, so as to limit the warning component, thereby preventing the warning component from being reset, and at the same time avoiding the phenomenon of the warning component being reset due to the cessation of leakage. When the high and low voltage complete electrical equipment body is subsequently maintained and inspected, its safety can be effectively improved.

[0018] 3. The leakage detection device and method of the high and low voltage complete electrical equipment, after solving the leakage of the high and low voltage complete electrical equipment body, pull the handle outward to allow the positioning block to retract into the inner cavity of the first through groove, and then reset the warning component by the arranged contraction spring, so that the warning component can be retracted into the inner cavity of the high and low voltage complete electrical equipment body again, and at the same time can assist in resetting the detection component, and through the arranged pulley, when the detection component contacts the connecting rod, the friction can be reduced, thereby improving the movement efficiency of the detection component and the connecting rod.

[0019] 4. The leakage detection device and method of the high and low voltage complete electrical equipment, after detecting leakage, the detection component also drives the mounting seat to move, so that the working component and the insulating panel installed in the inner cavity of the mounting groove can be directly moved out of the inner cavity of the high and low voltage complete electrical equipment body, so that when leakage occurs in the high and low voltage complete electrical equipment body, not only can the detection result be directly observed, but it is also convenient for the staff to directly maintain it, and moving the mounting seat to the outside can further improve the warning effect when leakage occurs. After the leakage situation is handled, the detection component can also drive the mounting seat and the insulating panel to reset.

[0020] 5. The leakage detection device and method of the high and low voltage complete electrical equipment can move left and right through the opening of the adjustment slot, and can drive the gear to rotate by rotating the set handle, so that the gear can mesh with the rack, so that the height of the leakage detector can be adjusted by the rack. When the working components of the high and low voltage complete electrical equipment body are subjected to leakage detection, the leakage detector can improve the accuracy of the leakage detection and effectively improve the safety during the detection. The dustproof belt can cover the adjustment slot at all times, which can effectively prevent dust and debris from entering the inner cavity of the high and low voltage complete electrical equipment body.

A first fixing rod 21 is installed in the inner cavity, and a contraction spring 22 is wound around the outer wall of the first fixing rod 21. One end of the contraction spring 22 is installed in the inner cavity of the high and low voltage complete electrical equipment body 1, and the other end of the contraction spring 22 is installed on the outer wall of the contraction block 20. The contraction block 20 is movably connected in the inner cavity of the high and low voltage complete electrical equipment body 1 and sleeved on the outer wall of the first fixing rod 21. The elastic force of the contraction spring 22 is less than the suction force of the iron core 11 and the magnetic block 15 after the electromagnet is formed.

By means of the dustproof belt 33, the adjustment slot 34 can be covered at all times, which can effectively prevent dust and debris from entering the inner cavity of the high and low voltage complete electrical equipment body 1.

[0027] A leakage detection method for high and low voltage complete electrical equipment, applied to the leakage detection device for the above-mentioned high and low voltage complete electrical equipment, comprises the following operating steps: S1: Install the working component of the high and low voltage complete electrical equipment body 1 on the mounting seat 4 through the mounting groove 5, and install the top of the coil 12 on the outer wall of the working component; S2: When leakage occurs in the working components of the high and low voltage complete electrical equipment body 1, the coil 12 will give magnetism to the iron core 11, thereby forming an electromagnet. At this time, the iron core 11 will absorb the magnetic block 15, so that the iron core 11 can absorb the bottom of the detection component 14. At this time, the detection component 14 will rotate at the fixed frame 13. The top of the rotated detection component 14 will contact and squeeze the connecting rod 18 through the pulley 19, so that the connecting rod 18 can drive the warning component 16 to extend out of the inner cavity of the high and low voltage complete electrical equipment body 1. The warning tape 17 on the side of the warning component 16 can be used to warn the staff of leakage. When the warning component 16 extends out of the inner cavity of the high and low voltage complete electrical equipment body 1, the leakage detection work of the high and low voltage complete electrical equipment body 1 is also completed; S3: When the warning component 16 extends out of the inner cavity of the high and low voltage complete electrical equipment body 1, the spring 31 will retract the positioning block 27 into the inner cavity of the high and low voltage complete electrical equipment body 1 through the slider 29. At this time, the positioning block 27 will fit on one end of the warning component 16, so as to limit the warning component 16; S4: When the detection component 14 rotates, its top will drive the mounting seat 4 to move in the direction of the warning component 16, so as to drive the insulating panel 3 to separate from the outer wall of the high and low voltage complete electrical equipment body 1. At this time, the working components installed in the inner cavity of the mounting groove 5 can be exposed to the outside. The staff can then perform maintenance on the working components and can also determine whether the high and low voltage complete electrical equipment body 1 is powered off. When the mounting seat 4 is moving, its two sides will move on the outer wall of the guide column 9 through the movable groove 6, and at the same time, it will drive the limit slider 7 to move on the outer wall of the movable block 8; S5: In normal state, the rack 40 is arranged on the right side of the insulating panel 3. When the leakage detection accuracy of the high and low voltage complete electrical equipment body 1 needs to be improved, the leakage detector 41 is installed on the rack 40, and the handle 35 is moved left and right to drive the adjustment block 36 to move left and right in the inner cavity of the adjustment slot 34. At this time, the adjustment block 36 drives the connecting frame 38 and the leakage detector 41 to move left and right through the gear 37. When it moves to the corresponding working component, the handle 35 is turned to drive the gear 37 to rotate so that it meshes with the rack 40. At this time, the height of the leakage detector 41 can be adjusted, and the leakage detector 41 is powered on through the external cable 42. At this time, the leakage detector 41 can detect the leakage of the working component at the corresponding position, thereby improving the detection accuracy; S6: When the leakage of the high and low voltage complete electrical equipment body 1 is solved, the leakage detector 41 and the external cable 42 are removed. After the iron core 11 loses its magnetism, the pull handle 32 is pulled outward so that the positioning block 27 can be separated from the outer wall of the warning component 16. At this time, the first fixing rod 21 will shrink the warning component 16 through the shrinking block 20, so that the warning component 16 can be reset. The reset warning component 16 can also assist the mounting seat 4 and the insulating panel 3 to be reset, thereby completing the overall leakage detection work.

A leakage detection method for high and low voltage complete electrical equipment, applied to the leakage detection device for the above-mentioned high and low voltage complete electrical equipment, characterized in that: The steps include: S1: installing the working component of the high- and low-voltage complete electrical equipment body (1) on the mounting seat (4) through the mounting groove (5), and installing the top of the coil (12) on the outer wall of the working component; S2: When leakage occurs in the working components of the high- and low-voltage complete electrical equipment body (1), the coil (12) will impart magnetism to the iron core (11), thereby forming an electromagnet. At this time, the iron core (11) will attract the magnetic block (15), so that the iron core (11) can attract the bottom of the detection component (14). At this time, the detection component (14) will rotate at the fixed frame (13). The top of the rotated detection component (14) will contact and squeeze the connecting rod (18) through the pulley (19), so that the connecting rod (18) can drive the warning component (16) to extend out of the inner cavity of the high- and low-voltage complete electrical equipment body (1). In combination with the warning tape (17) on the side of the warning component (16), the staff can be warned of leakage. When the warning component (16) extends out of the inner cavity of the high- and low-voltage complete electrical equipment body (1), the leakage detection work of the high- and low-voltage complete electrical equipment body (1) is also completed; S3: When the warning component (16) extends out of the inner cavity of the high-low voltage complete electrical equipment body (1), the spring (31) retracts the positioning block (27) into the inner cavity of the high-low voltage complete electrical equipment body (1) via the slider (29). At this time, the positioning block (27) fits against one end of the warning component (16), thereby limiting the warning component (16); S4: When the detection component (14) rotates, its top will drive the mounting seat (4) to move in the direction of the warning component (16), thereby driving the insulating panel (3) to separate from the outer wall of the high-low voltage complete electrical equipment body (1). At this time, the working components installed in the inner cavity of the mounting groove (5) can be exposed to the outside, and the staff can then perform maintenance on the working components. At the same time, it can also be determined whether the high-low voltage complete electrical equipment body (1) is powered off. When the mounting seat (4) moves, its two sides will move on the outer wall of the guide column (9) through the movable groove (6), and at the same time, it will drive the limit slider (7) to move on the outer wall of the movable block (8); S5: In normal state, the rack (40) is arranged on the right side of the insulating panel (3). When the leakage detection accuracy of the high and low voltage complete electrical equipment body (1) needs to be improved, the leakage detector (41) is installed on the rack (40), and the rotating handle (35) is moved left and right to drive the adjustment block (36) to move left and right in the inner cavity of the adjustment slot (34). At this time, the adjustment block (36) drives the connecting frame (38) and the leakage detector (41) to move left and right through the gear (37). After moving to the corresponding working component, the rotating handle (35) is rotated to drive the gear (37) to rotate so that it meshes with the rack (40). At this time, the height of the leakage detector (41) can be adjusted, and the leakage detector (41) is energized through the external cable (42). At this time, the leakage detector (41) can detect the leakage of the working component at the corresponding position, thereby improving the detection accuracy; S6: After the leakage of the high and low voltage complete electrical equipment body (1) is resolved, the leakage detector (41) and the external cable (42) are removed. After the iron core (11) loses its magnetism, the pull handle (32) is pulled outward so that the positioning block (27) can be separated from the outer wall of the warning component (16). At this time, the first fixing rod (21) will shrink the warning component (16) through the shrinking block (20) so that the warning component (16) can be reset. After the reset, the warning component (16) can also assist the mounting seat (4) and the insulating panel (3) to be reset, thereby completing the overall leakage detection work.
