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

Embodiment Construction

[0015] The present invention will be described in further detail below with reference to the accompanying drawings.

[0016] like figure 1 The shown simulation training system for load circuit breaker training includes a three-phase four-wire controlled voltage source, and the output of the voltage source is sequentially connected with leakage current, overload protection device (integrated protection board in the figure), isolation transformer, Each phase ammeter and isolating switch,

[0017] The simulation system of the present invention simulates a three-phase four-wire low-voltage power grid power supply system whose neutral point is directly grounded, and adopts the TN-C protection method, that is, the system adopts zero-connection protection inside the system, and the neutral line and the protection line are integrated. The leakage protector (I?n≥30mA, time ≤0.1S) simulates to realize safety protection; when a short circuit is caused by misoperation, the leakage protec...

Abstract

The invention relates to a simulated training system of a load breaker, comprising a three-phase four-wire program control voltage source, wherein the output of the voltage source is connected with a leakage current, an overload protection device, an isolation transformer, ammeters of all phases and an isolation switch in turn. The output end of the isolation switch is connected with a simulated load circuit, the simulated load circuit comprises a current relay controller and a three-phase four-wire load breaker, and the input end of the three-phase four-wire load breaker is correspondingly connected with the isolation switch. By using the system, the requirement on the training and the verification of related equipment can be met, trainees can study the use of the related equipment in a realer environment, and acquaint operation processes and protection, thereby facilitating system verification work and training assessment.

Description

technical field [0001] The invention relates to a simulation training system for training electricians, in particular to a training system for simulating subscriber line load and implementing protection when the tripping protection state is reached. Background technique [0002] In the middle and grassroots power distribution stations (substations) of the power system, there are power inspectors, power distribution operation and maintenance workers (on-duty workers in the substation), power distribution test and maintenance workers, rural power distribution operators, and relays. In order to ensure the safe and stable operation of the substation (station), technical training is required for protection workers, DC equipment maintenance workers, substation commissioning and maintenance workers, and electrical measuring instrument workers. [0003] Generally speaking, the training must first give theoretical explanations (explanation, pictures, multimedia teaching), and then ca...
