Problems solved by technology
[0003] During the use of the switchgear, the running status of the chassis may be abnormal. For example, the running track of the chassis may be blocked, causing the chassis to not run smoothly, or even the chassis may be stuck, causing the motor to burn or the cabinet to be damaged. body structure deformation
[0004] At present, it is usually judged whether the chassis vehicle is running abnormally according to the operating status of the switchgear. Since the minor abnormal operating conditions of the chassis vehicle will not affect the operating status of the switchgear, it is impossible to detect the abnormal operation of the chassis vehicle in time. The smaller abnormal operating conditions will gradually develop into larger abnormal operating conditions, which will eventually lead to changes in the operating status of the switchgear. Safety accidents and economic losses

Embodiment Construction
[0176] As mentioned above, there is currently no special inspection on the operating status of the chassis vehicle. Only after the switchgear is abnormal will the chassis vehicle be detected to determine whether the operation failure of the chassis vehicle causes the abnormal operation of the switchgear. , but when the chassis vehicle has minor abnormal operation conditions such as track blockage, it will not affect the normal operation of the switchgear, so it is impossible to detect the abnormal operation of the chassis vehicle in time, and when the abnormal operation of the chassis vehicle is found, it usually has already caused more serious consequences.
[0177] In the embodiment of the present invention, the target motor is used to drive the chassis car to run. When the chassis car runs abnormally, the input current of the target motor will change accordingly due to the change of the running resistance of the chassis car. Therefore, when the chassis car runs In the proce...

The invention provides a switch cabinet chassis truck operation state detection method and device, and relates to the technical field of electric power engineering. The switch cabinet chassis truck operation state detection method comprises the steps of: acquiring operation current data of a target motor, wherein the target motor is used for driving one chassis truck in one switch cabinet to operate, and the operation current data is used for representing an input current of the target motor in the process of driving the chassis truck to operate; and according to the operation current data andstandard current data, determining an operation state of the chassis truck, wherein the standard current data is used for representing an input current of the target motor in the process that the chassis trunk normally operates. According to the scheme, the operation abnormality of the chassis truck can be timely found.
Description
technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a method, a device and a computer-readable medium for detecting the running state of a switch cabinet chassis vehicle. Background technique [0002] Switchgear (Switchgear) is an electrical device mainly used in power systems to switch, control and protect electrical equipment during power generation, transmission, distribution and power conversion. The components in the switch cabinet mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. Inside the switch cabinet, the static contact of the circuit breaker is set in the cabinet, the pole of the circuit breaker is located on the chassis, the moving contact of the circuit breaker is located on the pole, there is an arc extinguishing chamber inside the pole, and the chassis is on the motor. Under the driving, the pole can be driven to run...
