Abstract
The utility model discloses a mechanical interlocking mechanism of an intelligent withdrawable switchgear, wherein a sliding plate (6) and a sector plate (8) are sleeved on a grounding switch operation shaft (7) in penetrating mode, a long circular hole capable of sliding vertically is arranged in the middle of the sliding plate (6), a roller (9) is fixed on the lower face of the sliding plate (6), a connection plate (5) is connected with the upper end of the sliding plate (6), the connection plate (5) is connected with a rocker arm (3) fixed on the left side of a shaft (4), a rocker arm (3) is further fixed on the right side of the shaft (4), and the right side rocker arm (3) is connected with a baffle (1) arranged on the grounding switch operation shaft (7) through a connection plate (2). By means of the mechanical interlocking mechanism, states of a manual mode and a power-driven mode are integrated, interlocking acted by the intelligent withdrawable switchgear under the manual mode can be acted under the power-driven mode, and the intelligent withdrawable switchgear can meet requirements under the two operation modes.
Description
Technical field
The utility model relates to a kind of interlocked operation mechanism of electric power withdraw-type switch cabinet.
Background technology
Withdraw-type switch cabinet is a mesolow electrical power distribution system indoor complete set of equipments commonly used.In rated voltage 3-35kV three-phase alternating current system, be widely used especially.Along with the proposition of intelligent grid notion, intelligent switch cubicle also becomes each switch cubicle producer development product of being eager.Because intelligent switch cubicle has electronic and manual two kinds of operator schemes, but in electric model, can not reach the requirement that " five is anti-" interlocks, so the interlocking in the original switch cubicle is no longer suitable in two kinds of patterns.
Summary of the invention
The purpose of the utility model is to provide a kind of makes intelligent withdraw-type switch cabinet can both reach the mechanical interlocking of " five is anti-" requirement down during operation at electronic and manual mode, makes the barrier propterty of intelligent switch cubicle more reliable.
The technical scheme that the utility model adopts is: a kind of intelligent withdraw-type switch cabinet mechanical interlock mechanism, it is characterized in that one slide plate and a fanning strip being arranged at earthed switch operating axis upper sleeve through, and slotted hole is arranged in the middle of the slide plate; Can slide up and down; Be fixed with a roller below the slide plate, the slide plate upper end is connected with a connecting plate, and connecting plate is connected with the connecting lever that is fixed on the axle left side; The axle right side also is fixed with a connecting lever, and the right side connecting lever is connected on the baffle plate of earthed switch operating axis through another connecting plate.
Under electric model, motor drives earthed switch operating axis rotates, and fanning strip is pushed down the roller pressed downward; Slide plate is to lower slider; The pulling connecting lever is downward, and connecting lever is depressed the baffle plate of earthed switch operating axis, and the state when closing a floodgate with completion earthed switch under the manual mode is identical.
Under manual mode; By operating personnel the baffle plate of earthed switch operating axis is depressed; Baffle plate drives connecting lever and through transmission slide plate is depressed; After operating personnel put earthed switch operation in place, the roller that fanning strip withstands below the slide plate made slide plate be in following position, and to close a floodgate be that state is identical to the completion earthed switch under this moment and the electric model.
The intelligent withdraw-type switch cabinet mechanical interlock mechanism that the utility model provides; Make intelligent withdraw-type switch cabinet under electronic and manual mode, can both realize the function of " earthed switch can not close a floodgate circuit breaker in the service position " and " earthed switch closing position circuit breaker can not by test position to the service position "; Unified the arriving together of state with manual mode and two kinds of patterns of electric model; The interlocking that makes intelligent withdraw-type switch cabinet under manual mode, can play effect can play effect equally under electric model, intelligent withdraw-type switch cabinet can both be met the demands under two kinds of operator schemes.
Description of drawings
Fig. 1 is the structural representation of the intelligent withdraw-type switch cabinet mechanical interlock mechanism of the utility model earthed switch when the separating brake position;
Fig. 2 is the structural representation of the intelligent withdraw-type switch cabinet mechanical interlock mechanism of the utility model earthed switch when closing position.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1, earthed switch operating axis baffle plate 2, connecting plate 3, connecting lever 4, axle 5, connecting plate 6, slide plate 7, earthed switch operating axis 8, fanning strip 9, roller
Shown in accompanying drawing, the intelligent withdraw-type switch cabinet mechanical interlock mechanism of the utility model is at earthed switch operating axis 7 upper sleeve throughs slide plate 6 and fanning strip 8 to be arranged, and slotted hole is arranged in the middle of the slide plate 6; Can slide up and down, be fixed with roller 9 below the slide plate 6, slide plate 6 upper ends are connected with connecting plate 5; Axle 4 two ends are fixed with two connecting levers 3; Left side connecting lever 3 cooperates with connecting plate 5, and right side connecting lever 3 cooperates with connecting plate 2, and connecting plate 2 lower ends are connected with earthed switch operating axis baffle plate 1.
During operate in manual mode, the operator presses earthed switch operating axis baffle plate 1, rotates earthed switch operating axis 7 with the earthed switch operating grip; After operation is accomplished; Fanning strip 8 is pushed down roller 9 in the interlocking device, and slide plate 6 can not up move, through the effect of axle 4 and connecting lever 3; Earthed switch operating axis baffle plate can not be moved up, as shown in Figure 2.
During the electric model operation, motor drives earthed switch operating axis 7 rotates, and fanning strip 8 drives slide plate 6 and moves down to down-pressure roller 9, through axle 4 and connecting lever 3, and the ground switching manipulation of crimping downwards axle bumper plate 1, after operation is accomplished, as shown in Figure 2.
