Abstract
The utility model discloses a mechanical interlock device, which comprises a rotating shaft, an interlocking lever, an interlocking rod, a guide sleeve, a spring, a drive plate and a supporting plate; wherein the interlocking lever is connected with a cabinet body by the rotating shaft and the guide sleeve is fixed on the cabinet body; the spring is arranged underneath the cabinet body; the interlocking rod is arranged in the guide sleeve and can slide freely. When the left cabinet is to close, the drive plate is pressed down; therefore the propulsive operating shaft of the right cabinet is locked by the interlocking lever in order to stop the right cabinet to close. The utility model has the advantages of simple structure, steady and reliable operation; meanwhile the device can avoid the misoperation that the two electricity supplies supply power simultaneously.
Description
The utility model relates to the mechanical interlocks between a kind of adjacent two switch cubicles.
Interlock between adjacent two switch cubicles adopts electrical interlock now, electrical equipment interlock complex structure, its effect must be converted into mechanical action by the electrical equipment action, because the unsteadiness of electric elements, therefore the fault point is many, occur unreliable phenomenon easily, particularly under the situation of secondary power supply dead electricity, the electrical equipment interlocking is ineffective, at this moment the misoperation that the two-way power supply send electricity simultaneously may take place, and causes whole electrical system operation disorderly.
The purpose of this utility model be to provide a kind of simple in structure, stable operation is reliable, the mechanical interlocks that the two-way power supply send electric misoperation simultaneously can not take place.
The purpose of this utility model is achieved like this, this mechanical interlocks, comprise cabinet, a left side, circuit breaker is housed, a left side in the right cabinet, right two cabinet breakers are controlled by mechanical interlocks, and mechanical interlocks is by rotating shaft, linking lever, blocking lever, fairlead, spring, support plate is formed, and linking lever connects with cabinet by rotating shaft, the linking lever two ends are connected to support plate, fairlead is fixed on the cabinet, and spring is housed respectively below, and blocking lever places in the fairlead, can be free to slide, support plate connects with the linking lever two ends, has a circular hole in the support plate, and insert in it the blocking lever lower end.When left cabinet breaker is switched on closing operation, depress drive plate, by linking lever will be on the right cabinet blocking lever item the right cabinet forward operation axle of locking, make the right cabinet breaker closing operation of can't switching on.As the right cabinet breaker closing operation of switching on, must earlier left and right two cabinets be fallen back on reset mode, again that left cabinet forward operation shaft lock is fixed, make the left cabinet breaker closing operation of can't switching on.
Because this mechanical interlocks adopts linking lever, blocking lever to carry out mechanical interlocking, makes left and right two cabinet breakers can not enter the service position simultaneously, simple in structure, stable operation is reliable, the two-way power supply can not take place send electric misoperation simultaneously.
The utility model is described in further detail below in conjunction with accompanying drawing
Fig. 1 is the mechanical interlocks structural representation between adjacent two switch cubicles
Fig. 2 is the mechanical interlocks side-looking structural representation of handcart-type left-handed opening cabinet
Fig. 3 is linking lever, drive plate, support plate connection diagram
With reference to Fig. 1, Fig. 2, Fig. 3, this mechanical interlocks, comprise a left side, right cabinet 2,14, circuit breaker is housed in the cabinet, a left side, right two cabinet breakers are controlled by mechanical interlocks, mechanical interlocks is by rotating shaft 17, linking lever 18, blocking lever 7,12, fairlead 5,10, spring 4,13, support plate 3,15 form, linking lever 18 is by rotating shaft 17 and cabinet 2,14 connect, linking lever 18 two ends are connected to support plate 3,15, fairlead 5,10 are separately fixed at cabinet 2, on 14, spring 4 is housed respectively below, 13, blocking lever 7,12 place fairlead 5 respectively, in 10, can be free to slide, drive plate 8,9 respectively by rotating shaft 1, rotating shaft 16 is connected with linking lever 18, and is rotatable, when linking lever 18 two ends move up and down, keep drive plate 8,9 plumbness, support plate 3,15 are connected support plate 3 with linking lever 18 two ends, have a circular hole 20 in 15, blocking lever 7, insert in it 12 lower ends, circular hole 20 diameters are greater than blocking lever 7,12 diameters, make blocking lever 7,12 have move place within it, when support plate 3,15 when moving up and down, and keeps blocking lever 7,12 is vertical, blocking lever 7, there is a projection 21 in 12 stage casings, are subjected to support plate 3,15 support.When left and right switch cubicle 2,14 is in the inoperative position, mechanical interlocks is in reset mode, linking lever 18 is in poised state under the effect of spring 4,13, when left cabinet 2 circuit breakers are switched on closing operation, handcart 19 shaken enter the service position, depress drive plate 8 simultaneously, spring 4 stretches, by linking lever 18 right cabinet 14 blocking levers 12 tops are gone up the right cabinet forward operation axle 11 of locking and compressed spring 13, make right cabinet 14 can't enter the service position, the right cabinet 14 circuit breakers closing operation of can't switching on.As the right cabinet 14 circuit breakers closing operation of switching on, must earlier left and right two cabinets be fallen back on reset mode, again with left cabinet forward operation axle 6 lockings, make the left cabinet 2 circuit breakers closing operation of can't switching on.
The utility model is applicable to the mechanical interlocking between adjacent two switch cubicles.
