Split-phase breaker hydraulic operation mechanism training device

Abstract

The invention discloses a split-phase breaker hydraulic operation mechanism training device, which comprises a background computer and a training cabinet connected with the background computer, wherein the training cabinet is internally provided with a fault simulator, a split-phase breaker, a split-phase breaker operating mechanism and a split-phase breaker 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 corresponding touch point of each fault setting relay is respectively connected in a control branch circuit needing to simulate the fault in the split-phase breaker control loop through a series manner or a parallel manner. The split-phase breaker hydraulic operation mechanism training device comprises the same circuit structure, logic relation and external presentation as a secondary control loop of a true hydraulic operation mechanism breaker; and with the adoption of the split-phase breaker hydraulic operation mechanism training device, a primary wire connection part does not exist, 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 a phase-splitting circuit breaker of a hydraulic operating mechanism in the electric power industry, in particular to a training device for a hydraulic operating mechanism of a phase-splitting circuit breaker. Background technique [0002] Once the circuit breaker in the substation is put into operation, the circuit breaker is not allowed to be operated casually. Once a fault occurs, it is difficult to reproduce the fault. 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 i...

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

[0005] Since there is no relatively mature training device for the hydraulic operating mechanism of the split-phase circuit breaker, it is difficult to carry out relevant training
