Abstract
The utility model discloses a mid-arrangement type interlocking device of a dual power switch cabinet. The technical scheme is that a locking round disc is connected with a pull rod and a crank arm on a rotating shaft through the pull rod and an adjusting nut, the rotating shaft is fixedly installed on a bending plate of a middle separation plate, and the crank arm fixed on the other side of the rotating shaft is connected with a handcart interlocking device on a mid-arrangement guide rail through the pull rod to form the interlocking device. The interlocking device is easy to manufacture, convenient to install, simple to operate and reliable in interlocking.
Description
Technical field
The utility model relates to a kind of novel interlock of electrical power distribution system switch cubicle.
Background technology
In electrical power distribution system, need a kind of duplicate supply to switch cabinet and control motor or other equipment; A kind of novel switched cabinet that needs double-throw disconnecting switch and handcart type breaker to be used is wherein just arranged; In order to realize this novel switched cabinet " five anti-" interlocking; And realize that isolating switch and circuit breaker according to correct operating sequence operation, just need a kind of novel interlock.
The utility model content
The purpose of the utility model is exactly to design a kind of novel interlock, realizes this novel switched cabinet " five anti-" interlocking.
The technical scheme of the utility model interlock is: the locking disk links to each other with connecting lever in the rotating shaft through pull bar, adjusting nut and pull bar; Rotating shaft is fixed on the bent plate that is installed in median septum; The fixing connecting lever of rotating shaft opposite side is connected with handcart interlock on the mid-cabinet guide rail through pull bar, and this has just constituted this novel interlock.
The operation principle of the utility model interlock is: when the operation double-throw disconnecting switch; Need get to the disjunction locked position of coupler to the locking disk, and along with the rotation of locking disk handle, pull bar, adjusting nut and pull bar also drive connecting lever thereupon and rotate; Thereby drive the handcart interlock on the mid-cabinet guide rail through rotating shaft drive connecting lever, pull bar; Handcart can not be advanced, still in test position, thus can not operating breaker when realizing disconnecting switch operation; Work as circuit breaker cart; When test position is advanced to the service position; The handcart interlock drives connecting lever through pull bar and rotates, and connecting lever drives connecting lever through rotating shaft, through pull bar, adjusting nut and pull bar; Thereby make the locking disk can not get to the disjunction locked position of coupler, can not disconnecting switch operation when the service position thereby be implemented in circuit breaker.The utility model interlock is made simple and easy, easy for installation, simple to operate, and interlocking is reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model interlock;
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1, locking disk 2, pull bar 3, adjusting nut 4, pull bar 5, median septum 6, bent plate 7, connecting lever 8, connecting lever 9, pull bar 10, handcart interlock 11, rotating shaft
Shown in accompanying drawing; The technical scheme of the utility model interlock is: locking disk 1 links to each other with connecting lever 7 in the rotating shaft 11 through pull bar 2, adjusting nut 3 and pull bar 4; Rotating shaft 11 is fixed on the bent plate 6 that is installed in median septum 5; The fixing connecting lever 8 of rotating shaft 11 opposite sides is connected with handcart interlock 10 on the mid-cabinet guide rail through pull bar 9, and this has just constituted this novel interlock.
The operation principle of the utility model interlock is: when the operation double-throw disconnecting switch; Need get to the disjunction locked position of coupler to locking disk 1, and along with the rotation of locking disk handle, pull bar 2, adjusting nut 3 and pull bar 4 also drive connecting lever 7 thereupon and rotate; Thereby drive the handcart interlock 10 on connecting lever 8, the mid-cabinet guide rail of pull bar 9 drives through rotating shaft 11; Handcart can not be advanced, still in test position, thus can not operating breaker when realizing disconnecting switch operation; Work as circuit breaker cart; When test position is advanced to the service position; Handcart interlock 10 drives connecting lever 8 through pull bar 9 and rotates, and connecting lever 8 drives connecting lever 7 through rotating shaft 11, through pull bar 2, adjusting nut 3 and pull bar 4; Thereby make locking disk 1 can not get to the disjunction locked position of coupler, can not disconnecting switch operation when the service position thereby be implemented in circuit breaker.The utility model interlock is made simple and easy, easy for installation, simple to operate, and interlocking is reliable.
