Isolation disconnecting link electric operating mechanism training device

Abstract

The invention discloses an isolation disconnecting link electric operating mechanism training device, which comprises a background computer and a training cabinet, wherein the training cabinet is provided with a fault simulator, an isolation disconnecting link, an isolation disconnecting link operation mechanism and an isolation disconnecting link control loop connected with the training cabinet in a controlling manner, wherein the fault simulator comprises a group of fault setting relays and a relay control circuit connected with the fault setting relays in a controlling manner; the fault simulator is connected with the background computer through a communication line; and the contact of each fault simulator is respectively connected in a control branch circuit needing to simulate the fault in the isolation disconnecting link control loop in a series manner or a parallel manner. The isolation disconnecting link electric operating mechanism training device comprises the same circuit structure, logic relation and external presentation as a secondary control loop of a true electric operating mechanism isolation disconnecting link; and with the adoption of the isolation disconnecting link electric operating mechanism training device, a primary wire connection part does not exist, and the operation mechanism and a control loop and the like are remained, and the fault simulator which is in communication connection with the background computer is increased.

Description

technical field [0001] The invention relates to training equipment for an electric operating mechanism of an isolated knife switch in the electric power industry, in particular to a training device for an electric operating mechanism of an isolated knife switch. Background technique [0002] Once the isolation switch in the substation is put into operation, the isolation switch is not allowed to be operated casually, and once a fault occurs, it is difficult to reproduce the fault. [0003] The secondary equipment and its circuits in the power system realize the monitoring, control, adjustment and protection of the primary equipment, and can reflect the operating conditions of the primary equipment. When the primary equipment is abnormal or fails, it can quickly send a signal and quickly remove the fault. equipment. Therefore, the secondary equipment and its circuits are an important guarantee for the safe, stable and economical operation of the power system, and are an indi...

AI Technical Summary

Problems solved by technology

However, the existing simulation equipment is only a small simulation system, which is very different from the real system equipment. It is impossible to deeply understand the performance indicators, technical parameters, and the cooperation and interrelationship between the systems and other equipment.

The training method using this small simulation equipment is highly theoretical but lacks practical training, which makes the training effect not good

If you go to the site for training, the personal safety of the trainees cannot be guaranteed, and the on-site equipment may be damaged

[0006] Since there is no relatively mature training device for the electric operating mechanism of the isolation knife switch, it is difficult to carry out relevant training
