Problems solved by technology

[0003] The operating mechanisms of circuit breakers and isolating switches that are usually visible are mostly equipment in operation on site. Electric maintenance personnel's access to equipment is limited by whether they have on-site work, and there are few opportunities for training.
At the same time, there is a risk of reducing the reliability and durability of the equipment and even causing equipment failure when performing defect elimination exercises on the field equipment.
In addition, there are occasional opportunities to use the spare parts of the operating mechanism for training, but the equipment used for training is often of a single model, and it is difficult to solve the training problem of many types of equipment on site

Abstract

The invention relates to a universal elimination simulation method for the simulation of electrical control circuits of substation equipment, drawing a simplified diagram of the control circuit and printing it on paper; setting the paper on a universal board, and simplifying the The terminals of each component in the figure are aligned with the hole; use the analog multimeter to contact the hole to identify the component corresponding to the hole currently tested, and display the power parameter of the component on the analog multimeter. The invention can simulate various control loops that need to be tested, so that the training of maintenance personnel is more convenient.

Description

technical field [0001] The invention relates to the field of electric equipment testing, in particular to a universal defect-eliminating simulation method for electrical control circuits of substation equipment. Background technique [0002] Circuit breakers and disconnectors are important components of power systems. Modern circuit breakers and isolating switches are all operated by electrical control, and the failure of the electrical control operating mechanism mainly occurs in the control loop. Therefore, eliminating control loop defects is an important skill for electric power maintenance personnel to solve circuit breaker and isolating switch faults, and it is also the focus and difficulty of substation maintenance work. At present, electric power maintenance personnel mainly use physical equipment to practice this skill, and there is a lack of a convenient and low-cost practice device. [0003] The operating mechanisms of circuit breakers and isolating switches that...
