Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, in one embodiment, the circuit breaker actuator performance detection apparatus may include a high voltage circuit breaker actuator 101, a controller 102, a power supply 103, an electromagnetic damping device 104, and a rubber damping device 105. An output shaft 1041 of the electromagnetic damping device 104 is connected with the high-voltage circuit breaker operating mechanism 104, and the other end of the electromagnetic damping device 104 is connected with the rubber damping device 105; the rubber damping device 105 is fixed relative to the bearing mechanism; the input end of the controller 102 is connected with the high-voltage circuit breaker operating mechanism 101, and the output end is connected with the power supply 103; the power supply 103 is used for supplying power to the electromagnetic damping device 104.
When the high-voltage circuit breaker operating mechanism 101 starts switching off or switching on, the controller 102 is triggered to output a power supply signal to the power supply 103; the power supply 103 supplies power to the electromagnetic damping device 104 according to the power supply signal; the electromagnetic damping device 104 and the rubber damping device 105 are used for eliminating power consumed in the process of opening or closing the high-voltage circuit breaker operating mechanism 101. The bearing mechanism is a mechanism for fixing the performance detection device of the circuit breaker operating mechanism, and can be, for example, the ground, a base fixed on the ground, and the like.
According to the performance detection device of the circuit breaker operating mechanism, when the high-voltage circuit breaker operating mechanism 101 starts opening or closing, the controller 102 is triggered, the controller 102 controls the power supply 103 to be electrified by the electromagnetic damping device 104, the output power of the power supply 103 is controlled by the controller 102, the output power of the power supply 103 corresponds to the power consumed when the circuit breaker opens or closes, after the opening or closing is finished, the power supply of the electromagnetic damping device 104 is cut off, and the residual energy of the opening or closing is absorbed by the rubber damping device 105, so that the action of simulating the high-voltage circuit breaker can be realized, power training teaching is carried out, and the safety is high.
In one embodiment, the output shaft 1041 of the electromagnetic damping device 104 may be connected to the output shaft of the high voltage circuit breaker actuator or to a transmission. Wherein, the connection mode can adopt rigid connection, such as adopting shaft pin or metal flange connection; the connection may also be a flexible connection, for example with a damping device.
In one embodiment, the power supply 103 provides electric energy with a preset power to the electromagnetic damping device 104 according to the power supply signal, where the preset power is the same as the power consumed by the high-voltage circuit breaker operating mechanism 101 when opening or closing is started. The preset power may be obtained by a preliminary test. The preset power is used for simulating energy consumption elements (mainly referring to a circuit breaker body) in the circuit breaker, and the purpose that the preset power is the same as the power consumed when opening or closing is started is mainly to ensure that various performance parameters of the circuit breaker operating mechanism are not changed. The circuit breaker operating mechanism of the present embodiment may have the same structure as a general circuit breaker operating mechanism.
As an implementation manner, the power supply 103 may provide the electromagnetic damping device 104 with electric energy of a preset power by adjusting the magnitude of the supply current. In addition, the power supply 103 may also provide the electromagnetic damping device 104 with electric energy of a preset power by adjusting the magnitude of the power supply voltage.
When the high-voltage circuit breaker operating mechanism 101 starts switching off or finishes starting switching on, the controller 102 controls the power supply 103 to stop supplying power to the electromagnetic damping device 104; the residual energy of the high-voltage circuit breaker operating mechanism 101 after the opening or closing is started is completely absorbed by the rubber damping device 104, so that the damage caused by the vibration caused by the opening and closing of the circuit breaker can be greatly reduced.
Referring to FIG. 1, in one embodiment, the rubber damping device 105 may include a base 1051 and a rubber layer 1052. The base 1051 is fixed relative to the carrying mechanism; a rubber layer 1052 is disposed on the base 1051 and interferes with the electromagnetic damping device 104. Specifically, the rubber layer 1052 may be adhered to the base 1051, or may be disposed on the base 1051 in other ways that will be apparent to those skilled in the art, without limitation. The residual energy after the high-voltage circuit breaker operating mechanism 101 starts opening or starts closing is absorbed by the rubber layer 1052 of the rubber damping device 104, so that the damage caused by the vibration caused by the opening and closing of the circuit breaker is greatly reduced.
The rubber layer 1052 may be a multi-layer structure, and the layers are bonded together to form the rubber layer 1052. Of course, the rubber layer 1052 may have a single-layer structure, which is not limited thereto. The rubber layer 1052 may be based on the residual energy that needs to be absorbed.
Optionally, the performance detection device of the circuit breaker operating mechanism may further include a status indicator light. The state indicator lamp is connected with a control power supply loop of the high-voltage circuit breaker operating mechanism 101 and used for displaying the switching-on state and the switching-off state of the high-voltage circuit breaker operating mechanism 101, so that the current state of the high-voltage circuit breaker operating mechanism 101 can be conveniently and clearly known, and teaching is facilitated.
The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present invention, and are intended to be included within the scope of the present invention.
