Problems solved by technology

However, the existing fault simulation device has a single function and can simulate simple types of fault waveforms. In fact, the actual situation on site is complex, not only a single cable fault, but also connectors, T connectors or X-type connectors on the cable. Therefore, the development and design of a fault simulation device that can comprehensively simulate the fault types of power cables has become an urgent problem to be solved by the training centers of various power companies.

Abstract

The invention relates to the technical field of high voltage power cable fault simulating devices and especially a smart cable fault simulating device. The device includes a simulation high voltage cable, a fault simulator, an automatic transfer switch, a smart control center and a display. The smart control center controls the automatic transfer switch automatically and combines the simulation high voltage cable with the fault simulator so as to form different simulation waveforms and the different simulation waveforms are displayed by the display. By adopting the above structure, different cable faults can be set without setting a cable fault complex field, and cable fault locating training efficiency can be improved. Compared with the prior art, cable faults can be simulated accuratelyin a comprehensive manner. The device has advantages of setting convenience, simple operation and the like.

Description

technical field [0001] The invention relates to the technical field of high-voltage power cable fault simulation equipment, in particular to an intelligent cable fault simulation device. Background technique [0002] With the acceleration of urbanization, the scale of cities is getting bigger and bigger, people's demand for electricity is increasing year by year; the requirements of human environment are improving. In the past, overhead line power transmission not only failed to keep up with the development needs, but also will be replaced by cable line power transmission. In this way, the maintenance work of power cables is greatly increased, and the popularization and training of power cable fault detection personnel is a difficult problem. In order to make the training work smoothly, a power cable fault simulation device is needed to simulate various types of faults. However, the existing fault simulation device has a single function and can simulate simple types of fau...
