摘要： The present invention provides a circuit breaker, a circuit breaker overtravel adjustment method and a power system. The circuit breaker comprises an arc extinguishing structure, a moving contact, and a static contact. The circuit breaker further comprises: a driving assembly is connected to the moving contact, and the moving contact is driven to make contact with or separate from the static contact. The driving assembly has an accommodating cavity. A contact pressure spring is provided within the accommodating cavity and abuts between the moving contact and the driving assembly, and is used to apply a force to the moving contact toward the static contact when the circuit breaker is in a closed state. A detection assembly comprises a pressure detector and a distance sensor. The pressure detector is disposed between the contact pressure spring and the driving assembly, and measures the pressure value of the contact pressure spring when the moving contact and the static contact tightly abut. The distance sensor is used to detect the measure distance between the moving contact and the distance sensor so as to determine the overtravel between the moving contact and the static contact according to the pressure value and the detection distance. The circuit breaker has higher reliability.

摘要： The invention relates to a control unit (7) for a medium voltage switching apparatus (1).
The control unit is characterised in that said control unit (7) is adapted to carry out a diagnostic method (100) to check operating conditions of one or more components of said electric poles (2).
The diagnostic method (100) comprises the following steps:
- basing on a selected ideal position curve (C IP ), obtaining (101) one or more first curves (C Iv , C IT ) indicative of an ideal behaviour of said switching apparatus, during an opening manoeuvre or closing manoeuvre of the switching apparatus;
- basing on detection signals (P F , v F , T F ) provided by a closed-loop control arrangement (72) of said control unit, calculating (102) one or more second curves (C Av , C AT ) indicative of an actual behaviour of said switching apparatus, during an opening manoeuvre or closing manoeuvre of said switching apparatus;
- carrying out (103) a comparison procedure (150) among said first and second curves (C Iv , C IT , C Av , C AT ).-

摘要： Embodiments of the present disclosure provide a load switch. The load switch comprises: a wireless transmission circuit configured to generate a first control signal in response to a control command signal from a remote device; a control circuit coupled to the wireless transmission circuit and configured to generate a second control signal in response to a reception of the first control signal from the wireless transmission circuit; a switching circuit coupled to the control circuit and comprising a relay arranged in a circuit, the switching circuit being configured to control a state of the circuit by controlling the contacts of the relay in response to a reception of the second control signal. The load switch achieves intelligent wireless control with the same size as a conventional common contactor. In addition, the load switch can monitor and acquire the information about the states of the circuit and the contacts, and voltage and current of the circuit, so that the user can understand various information of the circuit and the load switch in time. This improves both user experience and safety of electricity.
