Detailed Description
The technical solution of the present invention will be further described with reference to the accompanying drawings and the detailed description.
The utility model discloses a five-prevention program locking structure of an air-filled cabinet grounding switch, which comprises a fixed plate 5, wherein a program lock 1 and an interlocking piece 2 are arranged on the fixed plate 5; the interlocking piece 2 is movably connected with the middle door interlocking piece 4 through a hexagonal rod 7; the connecting end of the hexagonal rod 7 is provided with a bowl-shaped plate part 3 and a fish-shaped stop piece 6. Wherein, the front and back of the bolt of the program lock 1 support against the gap of the interlocking piece 2. The interlocking member 2 is fixed to the fixing plate 5 by a copper ring with a self-tapping screw. The bowl-shaped plate 3 is provided with a notched portion. The fish-shaped stop piece 6 is provided with a fish head and a fish tail.
When the interlocking device is used, the interlocking piece 2 is fixed on the fixing plate 5 through a copper ring by using a self-tapping screw so as to be capable of freely sliding, then the program lock 1 is installed on the fixing plate, the front and the back of a bolt of the program lock 1 are abutted against the notch of the interlocking piece 2, and the program lock 1 is operated by using a key so as to drive the interlocking piece 2 to slide back and forth. This part is mounted on the operating mechanism.
Under the condition that the program lock 1 drives the interlocking piece 2 to retract, the fishtail of the fish-shaped stop piece 6 faces the program lock 1 and is arranged on the operating mechanism grounding operating hexagonal rod 7, at the moment, the fishtail of the fish-shaped stop piece 6 abuts against the interlocking piece 2, then the bowl-shaped plate lack piece 3 is arranged, and then the rest parts of the operating mechanism are arranged.
When the grounding switch is in a separated state, the gap of the bowl-shaped plate lack part 3 faces the program lock 1, the tail part of the fish-shaped stop piece 6 faces the program lock 1, the fish tail of the fish-shaped stop piece 6 abuts against the interlocking piece 2, at the moment, the program lock 1 cannot rotate, a key of the program lock 1 cannot be taken down, the program lock on the transformer mesh door cannot be operated, the middle door interlocking piece 4 cannot move towards the direction of the program lock 1 under the action of the bowl-shaped plate lack part 3, and at the moment, the grounding operation hole handle can be inserted into the grounding operation hole to control the grounding hexagonal rod 7 of the operation mechanism to rotate to close the grounding switch;
when the grounding switch is in a closed state, the bowl-shaped plate lacking part 3 and the fish-shaped stopping piece 6 rotate under the action of the grounding hexagonal rod 7 of the operating mechanism, at the moment, the gap of the bowl-shaped plate lacking part 3 faces back to the procedure lock 1, and the fish head of the fish-shaped stopping piece 6 faces towards the procedure lock 1.
Through the five-prevention program locking structure, the problem that the interval between the transformer chambers is controlled when the grounding switch of the charging cabinet is in a grounding state can be solved, the danger caused by opening the door of the transformer chamber when the switch is in a charged state is prevented, and the safety and reliability of the whole box transformer substation system are improved.
