Detailed Description
Referring to fig. 1 to 4, a specific structure of a preferred embodiment of the present invention is shown, including a disconnecting switch 20 and a VD4 breaker 30 disposed in a switch cabinet 10.
The isolating switch 20 is provided with a locking mechanism handle 21, and a fulcrum 40, a first interlocking rod 51, a second interlocking rod 52 and a third interlocking rod 53 are arranged in the switch cabinet 10; the first interlocking rod 51 is arranged on the handle 21 of the locking mechanism and is driven by the handle 21 of the locking mechanism to move up and down; the second interlock rod 52 passes through the fulcrum 40, and both ends of the second interlock rod 52 are respectively connected with the first interlock rod 51 and the third interlock rod 53, and the third interlock rod 53 is connected with the VD4 circuit breaker 30.
In this embodiment, an interlocking hook plate 54 is welded to a lower end of the first interlocking lever 51, and one end of the second interlocking lever 52 is mounted on the interlocking hook plate 54 and the other end thereof is hinged to a lower end of the third interlocking lever 53. Also, the second interlock lever 52 has an L-shape.
Detailed description the working principle of the present embodiment is as follows:
as shown in fig. 2, when the handle 21 of the locking mechanism is rotated to the opening/closing state, the first interlocking rod 51 is pulled upwards, the interlocking hook plate 54 on the first interlocking rod 51 pulls the second interlocking rod 52 upwards, the second interlocking rod 52 presses the third interlocking rod 53 through the fulcrum 40, the third interlocking rod 53 pulls down to trigger the switch of the VD4 circuit breaker 30 to open, so that the VD4 circuit breaker 30 is locked in the opening state and cannot be closed, and at this time, the circuit no-load opening/closing disconnecting switch can be ensured.
As shown in fig. 3, when the handle 21 of the locking mechanism is rotated to the working state, the first interlocking rod 51 moves downwards, the interlocking hook plate 54 on the first interlocking rod 51 moves downwards, the pulling on the second interlocking rod 52 is cancelled, the VD4 circuit breaker 30 opening interlocking plate resets, the opening locking of the VD4 circuit breaker 30 is released, and at this time, the VD4 circuit breaker 30 can be operated to open and close normally.
As shown in fig. 4, when the handle 21 of the locking mechanism is rotated to the maintenance state, and when the disconnecting switch 20 is in the closing state, due to the effect of the locking mechanism, the handle 21 of the locking mechanism cannot be rotated to the maintenance state, the handle 21 of the locking mechanism needs to be rotated to the breaking and locking state first, the logic sequence ensures that the VD4 breaker 30 is opened, at this time, the opening disconnecting switch 20 can be operated, the equipment in the cabinet is not charged, the safe maintenance can be performed, the handle 21 of the locking mechanism is rotated to the maintenance state, and the equipment can be opened for maintenance.
The utility model discloses a design key is: the VD4 circuit breaker and the isolating switch are mutually interlocked by arranging the fulcrum, the first interlocking rod, the second interlocking rod and the third interlocking rod in a matching way, so that the isolating switch is ensured to operate without load, and the personal safety of operators is effectively guaranteed.
The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
