Fig. 1 and fig. 2 are respectively a front side and a side structure schematic diagram of a 35Kv cubical switchboard valve interlocking device that the embodiment of the utility model provides.
In the figure:
1. the driving device comprises a driving lever, a left driving lever, a right driving lever, an upper valve, a lower valve, a right driving lever, a left guide rod, a right guide rod, a left guide rod, a right.
Detailed Description
Embodiments of the present invention will be described in further detail below. Details not described in the embodiments of the present invention belong to the prior art known to those skilled in the art.
The utility model discloses a 35Kv cubical switchboard valve interlocking device, the concrete implementation mode of its preferred is:
the four-bar linkage type automatic opening and closing device comprises a driving lever, an upper valve, a lower valve and a four-bar linkage mechanism, wherein the upper valve and the lower valve are respectively arranged on an upper guide rod and a lower guide rod, and the driving lever is respectively connected with the upper valve and the lower valve through the four-bar linkage mechanism.
The four-bar linkage mechanism comprises a first driving plate, a second driving plate, a third driving plate, a fourth driving plate and two support fixing points;
the lower end of the first driving plate is hinged with the driving lever, the upper end of the first driving plate is hinged with the middle of the second driving plate, the rear end of the second driving plate is hinged with one support fixing point, and the front end of the second driving plate is hinged with the lower valve;
the lower end of the driving plate III is hinged to the middle of the driving plate II, the upper end of the driving plate III is hinged to the rear end of the driving plate IV, the middle of the driving plate IV is hinged to the other support fixing point, and the front end of the driving plate IV is hinged to the upper valve.
The two sets of driving levers and the four-bar linkage mechanism are respectively arranged on two sides of the 35Kv switch cabinet valve interlocking device, one set of driving levers is connected with the left sides of the upper valve and the lower valve, and the other set of driving levers is connected with the right sides of the upper valve and the lower valve.
The utility model discloses a 35Kv cubical switchboard valve interlocking device, the switch board is safer when using and overhauing, can prevent that artificial error and maloperation from causing the loss for personnel's property. The interlocking design is the supplement and the perfection of five-prevention interlocking of the power distribution cabinet, and the practical requirements are met.
The specific embodiment is as follows:
as shown in fig. 1 and 2, the 35Kv switch cabinet valve interlocking device drives the upper and lower valves through a four-bar principle and a guide rod on the basis of the existing power distribution cabinet, so that the upper and lower valves are convenient to open and close, have accurate stroke positioning and small resistance and are not easy to damage and deform.
The linkage mainly comprises a left driving lever, a right driving lever, an upper valve, a lower valve, an upper guide rod, a lower guide rod, a driving plate and a support.
The working principle is as follows:
the 35kV breaker is pushed into the cabinet, the valve pressing devices on the left side and the right side of the bottom plate of the handcart of the breaker press the left upper part and the right upper part of a driving lever of the valve interlocking device of the 35kV switch cabinet, the circuit breaker presses the valve device to act on the driving lever of the valve in a consistent way by shaking the circuit breaker to move forwards continuously, so that the driving plate moves downwards, the second driving plate (utilizing a fixed point of the bracket) moves downwards and drives the lower valve to move downwards through the lower guide rod until the lower valve is opened, the driving plate III moves downwards while the driving plate II moves downwards, the driving plate IV (by utilizing a bracket fixing point) moves upwards to drive the upper valve to move upwards through the upper guide rod until the upper valve is opened, the whole movement enables the valve driving plate to move up and down through a certain angle by a lever principle, thereby driving the upper and lower valves to move under the limit of the upper and lower guide rods, and finally opening or closing the valves up and down.
When the breaker is pulled out of the cabinet, the valve moves in a linked reverse direction, and finally the valve is closed to block the charged part in the cabinet, so that the safety is ensured.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are all covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
