Embodiment 1

[0021] Such as Figure 1-3 As shown, an emergency opening and closing manipulator capable of remotely operating a circuit breaker includes a DC power supply 1, a signal receiving controller 2, and an electric motor 3 that are electrically connected in sequence, and also includes a remote controller that matches the signal receiving controller 2. The motor 3 is connected with a speed reducer 4, the output shaft of the speed reducer 4 is provided with an electromagnetic clutch 5, and the electromagnetic clutch 5 is provided with a handle splint, and the signal receiving controller 2 is connected with the electromagnetic clutch 5 signal. When the present invention is used, the handle splint tightens the operating handle of the circuit breaker, and the remote controller can send the electric motor 3 forward rotation and reverse rotation command signals, and after the signal receiving controller 2 receives, demodulates, and decodes, the electric motor 3 is controlled to rotate Afte...

Embodiment 2

[0023] The difference between this embodiment and Embodiment 1 is that the signal receiving controller 2 includes a signal amplification circuit, a demodulation circuit, and a decoding circuit sequentially connected by signals, and the forward rotation and reverse rotation of the handle splint are realized through the electromagnetic clutch 5 .

Embodiment 3

[0025] The difference between this embodiment and Embodiment 1 is that two distance sensors are provided on the adjustable bracket, and the distance sensors are connected to the signal receiving controller 2 with signals. When the operating handle of the circuit breaker is at the limit position of forward rotation and the limit position of reverse rotation, the two distance sensors are respectively triggered by the first splint 11, and the signal receiving controller 2 controls the handle splint to stop rotating.

Abstract

The invention relates to the technical field of power equipment, and solves the problem of inconvenience in operation when a circuit breaker cannot be remotely controlled in the prior art. An emergency switching-on and switching-off manipulator capable of remotely controlling and operating a circuit breaker comprises a direct-current power supply, a signal receiving controller and an electric motor which are electrically connected in sequence, and further comprises a remote controller matched with the signal receiving controller, a speed reducer is connected to the electric motor, an electromagnetic clutch is arranged on an output shaft of the speed reducer, and a handle clamping plate is arranged on the electromagnetic clutch. And the signal receiving controller is in signal connection with the electromagnetic clutch. When the manipulator is used, the handle clamping plate tightens an operation handle of the circuit breaker, the remote controller can send out forward rotation and reverse rotation instruction signals of the electric motor, the forward rotation and reverse rotation instruction signals are received, demodulated and decoded by the signal receiving controller to control the electric motor to rotate, the electric motor drives the handle clamping plate to rotate after being decelerated by the speed reducer, and operation on the circuit breaker is achieved.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to an emergency opening and closing manipulator capable of remotely operating a circuit breaker. Background technique [0002] The existing substation circuit breaker can be operated by remote control, but when the motor machine crashes or the network fails, the circuit breaker cannot be remotely controlled, resulting in delay and shutdown, which will lead to serious economic losses. When the circuit breaker cannot be operated by remote control, there are usually the following three processing methods: one is to manually operate the emergency opening device of the circuit breaker on site, which is likely to cause personal injury accidents; Remote control operation, this method takes a long time, delays the power transmission time, and has negative effects; the third is to stop the upper-level bus to isolate the fault circuit breaker. Although this method avoids the risk o...
