According to the scheme, the linkage lock connected with the circuit breaker is arranged, so that the drawer cannot be taken out when the main loop is a passage, and further, safety accidents such as electric shock are avoided. Simultaneously, through setting up the bus-bar cabinet and realizing acting as go-between in the top at the main cabinet body, avoid the electricity distribution room electric wire to influence in a jumble staff and maintain and pass. Through the other end of the main cabinet body is provided with the cable chamber, the operation before the cabinet is realized, and the cable is pulled behind the cabinet, so that the maintenance is more convenient. And the low-voltage draw-out type switch cabinet is convenient and quick to assemble by adopting a modular design.
According to a preferable scheme, an insulating steel plate is arranged between every two adjacent drawers, and the insulating steel plates are matched with the inner wall of the main cabinet body to form a drawer chamber.
According to the scheme, the insulating steel plates separate the drawers, so that the short circuit phenomenon is avoided.
One preferred scheme is, the interlocking lock includes electro-magnet and vertical connecting rod, the electro-magnet with the cooperation is inhaled to vertical connecting rod magnetism, the electro-magnet sets up the top of vertical connecting rod, the electro-magnet with the circuit breaker is established ties, vertical connecting rod runs through all the drawer room, be provided with a plurality of lock posts on the vertical connecting rod, it is a plurality of all be equipped with on the lateral wall of drawer with the locked groove of lock post looks adaptation, the opening of locked groove is down, works as when the circuit breaker is in the access state, vertical connecting rod receives the magnetic force attraction upward movement of electro-magnet, the lock post gets into in the locked groove.
According to the scheme, the electromagnet is used as a power source of the vertical connecting rod, when the circuit breaker is in a closed state, the electromagnet generates magnetic force to drive the vertical connecting rod to move upwards, so that the lock cylinder enters the lock groove to lock the drawer, and accidents are prevented.
Preferably, the locking groove is in an inverted right-angled trapezoid shape, and a right-angled end of the locking groove is far away from the cable chamber.
It can be seen from the above scheme that through adopting the design of the inverted right trapezoid, when the breaker is in the passage and the drawer is pulled, the lock column is forced to move upwards under the action of the inclined plane end of the right trapezoid, so that the breaker is better blocked, and the drawer can be pulled out when the breaker is in the passage.
One preferred scheme is that a limiting sliding groove matched with the vertical connecting rod is arranged on the main cabinet body.
According to the scheme, the vertical connecting rod is guided by the limiting sliding groove, so that the vertical connecting rod can run more accurately and more stably
According to a preferable scheme, a damping cushion block matched with the end part of the vertical connecting rod is arranged at the bottom of the main cabinet body, and a buffer glue is arranged between the electromagnet and the vertical connecting rod.
According to the scheme, the vibration generated by the movement of the vertical connecting rod is reduced by arranging the damping cushion block and the buffer glue, so that the damage caused by collision is further reduced, and the service life of the vertical connecting rod is prolonged.
One preferred scheme is that the bus cabinet is fixedly connected with the main cabinet body through bolts.
According to the scheme, the phenomena of deformation, stress concentration, easy rusting and the like caused by welding are avoided by adopting the bolt for connecting and fixing.
